It is Independence Day today in the US, and we’re in Washington, D.C. imageto see us some awesome fireworks!

Since today is July, 4th, and we are on Day 4 I figured it would be good to do a VSTT that dealt with numbers. The best one I know is how to display line numbers in Visual Studio:

Display Line Numbers:

Go to the Tools menu, then click on the Options… menu item. Find the Text Editor item in the list on the left. Then I recommend choosing All Languages. Next find and check the Line Numbers checkbox in the Display section on the right.

The image to the right will take you to a full size image if you want to see this in more detail.

imageOne of the best features most Internet browsers have is the ability to navigate backwards, and forwards, through your history of Web site pages you have visited. Don’t you wish you had this feature in Visual Studio? Well, you do. Here’s how you do it.

One option is to go to Visual Studio’s View menu and choose either Navigate Forward or Navigate Backward. An even more handy method is to use the following keyboard shortcuts:

Ctrl + – and Ctrl + Shift + –.

One cool thing about the way Visual Studio does this is that it will navigate backwards through different parts of Visual Studio, everything from forms you’ve open to code you’ve worked, and more.

Oh, the humanity! How I hate it when I get “The terminal server has exceeded the maximum number of allowed connections.”

image

Page Brooks and I were just talking about how it only happens to you when you are in a bit of a hurry, and need to get something done ASAP. You are allowed two remote terminal sessions.

The problem usually isn’t that there are too many people logged in. The problem is almost always that people disconnected from their without ending their session or logging out. So terminal services thinks the connection is still active, but just idle.

One option is to use the Computer Management Console, and choose Action, Connect to another computer…, Services and Applications, and then go to Terminal Services Manager and log off or disconnect the sessions.

I found out about a more powerful command line version that was able to work for me. I think the above didn’t work because our servers are virtualized.

  1. run the following from a command prompt: query session /server:servername
  2. Next run the following: reset session [ID] /server:servername

Ah, it just works. So much better now. Me and our servers are friends again.

imageIt happens all the time. You’re working in Visual Studio, and you need to work with an object that is in a namespace you haven’t declared yet. For example, you need to create a WebRequest in the System.Net namespace.

You have a few choices, some easy and some hard: You could add a using or import statement at the top of the class file as in “using System.NET”. You could fully qualify the object as in “System.Net.WebRequest”. You could try to click that tiny, tiny little red rectangle that will open the Smart Tag. You could type “CTRL + SHIFT + F10”. Or you could take the easy road and simply enter “Ctrl + .”.

“Ctrl + .” Rocks! Try it, you’ll love it!

With most things there are two ways to learn them: the easy way, and the hard way. Visual Studio 2008 is know exception. One option, the hard way, is to spend all of your precious time learning and memorizing hundreds of Visual Studio shortcut key combinations.

Quick, what is the shortcut to perform an incremental search, or to convert selected text to lower case, or to comment a selection of code? Everyone one of these has a handy shortcut key combination. Do you know them all? If not, did you know Visual Studio has a feature you can enable so that it will show you, or maybe I should say teach you, the shortcut keys for most commonly accessed menu and toolbar items?

It is called “Show shortcut keys in Screen Tips”. You have to enable “Show Screen Tips on toolbars” for this feature to work. Both items are located on the same screen for easy access.

Here’s what you need to do:

  • In Visual Studio go to Tools, and then Customize….
  • This will open the Customize dialog where you will now need to check both the “Show shortcut keys in Screen Tips” and “Show Screen Tips on toolbars” checkboxes.

From now on when you use Visual Studio it will display shortcut key combinations on menus and toolbar tooltips whenever you use them.

If you’ll click on the included image, you will see a larger more detailed screenshot of the areas discussed.

imageI’ve committed myself to taking the knowledge I have learned, over the years, and sharing it more with others. Last month I did 30 Days of .NET Windows Mobile Applications, and this month I intend to do 31 Days of Visual Studio 2008 Tips & Tricks.

The material will come from a presentation I have given many times at different code camps and user groups. One of the goals of the series is to start a “conversation” with my readers. I want to share some of my best tips and tricks for Visual Studio, and in return I hope you’ll share some of yours with us as well.

Another goal I have is for the information to be quick and easy to “digest” and as worthwhile as possible. Give me a few minutes every day this month, and I bet I’ll make a difference in how productive you are every day.

 

Here’s the introduction from my Visual Studio 2008 Tips & Tricks presentation to set the stage:

“Visual Studio .NET is filled with hundreds of features that make our lives as developers more efficient. The number of features that Visual Studio .NET contains is immense. The Visual Studio .NET Tips and Tricks presentation is a compilation of my favorite, and most popular, tips and tricks for this great IDE. Developers who are unaware of these timesaving features miss out on opportunities to increase their programming productivity and effectiveness. This Visual Studio .NET Tips and Tricks presentation is meant to explain how to use Visual Studio .NET more effectively.”

image And there you have it: 30 .NET Windows Mobile Applications in 30 Days!

I really liked yesterday’s application, Community Megaphone Reader. I think it was because it was a Windows Mobile mashup application. And we can look forward to many more of these types of applications to come our way.

 

image

Trippr

You’ve probably already figured out what this application does. That’s right it takes your current GPS position and pulls back pictures that are geotagged for the area you are in. So while you are riding down the road you can flickrscan for photos taken near you, possibly as close as the block you are on.

Really cool idea I think. I’ll probably hook this up to the dashboard of my car and just let it run while I drive around. It should be lots of fun to just see what I see.

The UI is basic sterile white, but I wanted the photos to be the star of the show so I went with the one uber true neutral color.

Control are very simple: Update, Menu, GPS, GPS Start, GPS Stop, About, and Exit. Update is the main feature. Any time it is pressed new photos are downloaded.

Again for this project we looked to the GPS Intermediate Driver Reference, it has served us well these 30 days and I really highly recommend it. If you need to do a Windows Mobile GPS application use this and you are almost done.

Another great API I found is the Flickr.Net API. If you need to connect to Flickr in .NET or .NET Compact Framework this is great. It does all the heavy lifting for you! I was up and running in minutes!

“The Flickr.Net API is a .Net Library for accessing the Flickr API. Written entirely in C# it can be accessed from with any .Net language in .Net Framework 1.1, .Net Framework 2.0, .Net Compact Framework 2.0 and Mono.”

Update Method

   1: if (gpsPosition == null || !gpsPosition.LatitudeValid || !gpsPosition.LongitudeValid)
   2:      return;
   3:  
   4:  double minimumLongitude = gpsPosition.Longitude - 1;
   5:  double minimumLatitude = gpsPosition.Latitude - 1;
   6:  double maximumLongitude = gpsPosition.Longitude + 1;
   7:  double maximumLatitude = gpsPosition.Latitude + 1;
   8:  
   9:  string apikey = "get_your_own_flickr_key";
  10:  Flickr flickr = new Flickr(apikey);
  11:  
  12:  PhotoSearchOptions options = new PhotoSearchOptions();
  13:  options.BoundaryBox = new BoundaryBox(minimumLongitude, minimumLatitude, maximumLongitude, maximumLatitude);
  14:  options.Extras |= PhotoSearchExtras.Geo;
  15:  options.PerPage = 10;
  16:  options.SortOrder = PhotoSearchSortOrder.InterestingnessAsc;
  17:  
  18:  Photos photos = flickr.PhotosSearch(options); 
  19:  StringBuilder stringBuilder = new StringBuilder();
  20:  
  21:  foreach(Photo photo in photos.PhotoCollection)
  22:      stringBuilder.AppendFormat(@"<img src=""{0}"" style=""border: 1px black solid; padding: 0px; margin: 1px"" />", photo.ThumbnailUrl);
  23:  
  24:  webBrowser.DocumentText = stringBuilder.ToString();

Possibilities:

Obviously this needs an auto-update feature and settings for those of use who will use it on the road. If I click on a picture I’d love to see a larger view of it as well. and a details listing telling me more about the photo would be great.

imageWe only have one more day left in our 30 days of .NET [Windows Mobile Applications]. Where do we go from here?

I’m really happy with the 30 Days of .NET so I do think I will continue that in one format or another for some time. It’s been a blast. And everyone knows my passion for Windows Mobile programming so we keep finding way to work that in there as well.

I haven’t quite decided what I’ll do for next month but I’m sure it’ll only get better as we move forward.

There have been a lot of request for applications that haven’t made it on deck yet, and obviously they aren’t all going to get done tomorrow. But I think I’ll be able to throw in some Bonus Day of .NET or Return of Day of .NET and knock some of them out over time.

My goal is to take all the existing content and clean it up some and make more through and detailed learning materials to really help beginners take off with Windows Mobile.

Hope you’ll join me on the road ahead…

Only One Day Left…

Not too long ago Page Brooks and myself made the three and a half hour drive from Florence, SC to Greensboro, NC to attend the Ineta Carolina Community Leadership Summit '08. This was a great event and there we meet a lot of the local Ineta user group leaders. We also meet Andrew Duthie, aka DEvHammer. One issue that rose to the top of things we wanted to work on improving at the leadership summit was awareness of events that are occurring in the local regional area. That’s when Andrew told everyone about the project he has been working on: Community Megaphone.

I love have information at my fingertips, so I decided to write a tie-in application:

image

image

Community Megaphone Reader

Basically, this application connects to the Community Megaphone RSS feed and pulls down event data. Then it takes your current GPS position and calculates your distance from each event. Finally, it takes all the events and sorts then so you can find the event that is the closest to you. This is a great application for the traveling .NET geek. Where ever you are you can find great .NET events to attend.

The UI is paying homage to Andrew’s Community Megaphone site. I tried to match the basic colors to keep it familiar. The hyperlinks are active and will take you the event’s page on Community Megaphone. The menu only has a few options: Refresh, About, and Exit.

An application like this is really exciting, because it is tying the world of mobile together with the world wide web.

These types of mashup applications will contitue to take of for years.

LoadRss Method

   1: public static DataSet LoadRss(string requestUriString)
   2: {
   3:     HttpWebRequest feed = HttpWebRequest.Create(requestUriString) as HttpWebRequest;
   4:     StreamReader streamReader = new StreamReader(feed.GetResponse().GetResponseStream());
   5:  
   6:     string rssXml = streamReader.ReadToEnd();
   7:     rssXml = rssXml.Replace(@"<?xml version=""1.0"" encoding=""utf-8""?>", string.Empty);
   8:  
   9:     StringReader stringReader = new StringReader(rssXml);
  10:  
  11:     DataSet dataSet = new DataSet();
  12:     dataSet.ReadXml(stringReader);
  13:  
  14:     return dataSet;
  15: }

 

GetEvents Method

   1: public static List<Item> GetEvents(DataSet dataSet, GpsPosition gpsPosition)
   2: {
   3:     List<Item> items = new List<Item>();
   4:  
   5:     foreach (DataRow dataRow in dataSet.Tables["item"].Rows)
   6:     {
   7:         Item item = new Item();
   8:         item.Title = (string)dataRow["title"];
   9:         item.Description = (string)dataRow["description"];
  10:         item.Link = (string)dataRow["link"];
  11:         item.PublishDate = DateTime.Parse((string)dataRow["pubDate"]);
  12:         item.Latitude = Double.Parse((string)dataRow["lat"]);
  13:         item.Longitude = Double.Parse((string)dataRow["long"]);
  14:  
  15:         if(gpsPosition.LatitudeValid && gpsPosition.LongitudeValid)
  16:             item.Distance = GeoCodeCalc.CalcDistance(gpsPosition.Latitude, gpsPosition.Longitude, item.Latitude, item.Longitude);
  17:  
  18:         items.Add(item);
  19:     }
  20:  
  21:     items.Sort(delegate(Item item1, Item item2)
  22:     {
  23:         return item1.Distance.CompareTo(item2.Distance);
  24:     });
  25:  
  26:     return items;
  27: }

Display Events Method

   1: public static string DisplayEvents(List<Item> events)
   2: {
   3:     StringBuilder stringBuilder = new StringBuilder();
   4:  
   5:     foreach (Item item in events)
   6:     {
   7:         stringBuilder.Append(@"<span style=""color: #FFFFFF;font-weight:bold;"">");
   8:         stringBuilder.AppendFormat(@"<a href=""{0}"" style=""color: #DBB94F;"">{1}</a><br/><br/>", item.Link, item.Title);
   9:         stringBuilder.AppendFormat(@"{0}<br/><br/>", item.Description);
  10:         stringBuilder.AppendFormat(@"<b>Distance: <span style=""color: #DBB94F;"">{0} miles</span></b><br/>", item.Distance.ToString("0.00"));
  11:         // stringBuilder.AppendFormat(@"<b>{0}</b><br/>", item.PublishDate);
  12:         // stringBuilder.AppendFormat(@"{0}<br/>", item.Latitude);
  13:         // stringBuilder.AppendFormat(@"{0}<br/>", item.Longitude);
  14:         stringBuilder.AppendFormat(@"<br/><br/>");
  15:         stringBuilder.Append(@"</span>");
  16:     }
  17:  
  18:     return stringBuilder.ToString();
  19: }

Possibilities:

Andrew recently added iCalendar file support to Community Megaphone. This would be a great feature to add to a Windows Mobile application, and it is totally doable. The HTML could be a little more fancy maybe even use a few 16x16 fonts for a little personality.

Only 2 Days Left…

Today’s application is CallBlock. It is designed to watch incoming calls, and check and see if they match any on the block phone numbers list. If they do match then the phone is “blocked”.

 

image

CallBlock

The first thing you should notice is the flashy logo at the top of the form. I create this logo with an online 3D logo generator. The one simple touch adds a lot of professional polish to the application. I really like red and white so I didn’t change the background color this time. But I am starting to wish I had. It seems a little “blah” to me now.

Next we have our phone number input text box. The user enters the phone number here, and presses the Block menu item to add it to the block number list below. On the main menu we also have options to Unblock, and Unblock All. And we have our almost universal About and Exit menu items.

There are two main pieces to this application. One part is the State and Notification Broker code to give us an event to catch incoming phone calls.

I actually got myself painted into a corner, I assumed you could just programmatically ignore of phone call but it isn’t that simple. Fortunately, a good friend of mine, Lou Vega, came up with a very slick workaround for this. And that is the second part which is the keybd_event method that allows us to send keypresses to the OS to Ignore the phone call.

CallBlock Core Code

   1: const int KEYEVENTF_KEYDOWN = 0x0;
   2: const int KEYEVENTF_KEYUP = 0x2;
   3:  
   4: [DllImport("coredll.dll", EntryPoint = "keybd_event", SetLastError = true)]
   5: internal static extern void keybd_event(byte bVk, byte bScan, int dwFlags, int dwExtraInfo);
   6:  
   7: SystemState phoneIncomingCall = new SystemState(SystemProperty.PhoneIncomingCall);
   8: private void frmMain_Load(object sender, EventArgs e)
   9: {
  10:     phoneIncomingCall.Changed += new ChangeEventHandler(phoneIncomingCall_Changed);
  11: }
  12:  
  13: void phoneIncomingCall_Changed(object sender, ChangeEventArgs args)
  14: {
  15:     string phoneNumber = RemoveText(SystemState.PhoneIncomingCallerNumber);
  16:  
  17:     if(listBoxBlockedNumbers.Items.Contains(phoneNumber))
  18:     {
  19:         keybd_event(115, 0, KEYEVENTF_KEYDOWN, 0);
  20:         keybd_event(115, 0, KEYEVENTF_KEYUP, 0);
  21:     }
  22: }

 

Possibilities:

It would be easy to add support for blocking SMS text messages as well. We’ve done all the code for this already in previous applications. Also the application could really use a persistent data store to remember number to block in case the user closes the application. It would be nice to allow user formatting of entered phone numbers for increased readability.

So Page Brooks was talking with me earlier this week and he had a great idea for another Windows Mobile application. He wants an application that will repeat alerts for missed phones and text messages. I have to admit this is something I could use myself. So I figured I take a crack at it today, since it would make for a fun, simple, Friday app.

 

image

Repeatr

I decided to change up the naming format and play of the popular Web 2.0 naming conventions giving us the name: Repeatr. I have to admit, it is kind of catchy.

I searched for “Web 2.0 Logo Creator” and pretty much went with the first one I saw. This gave me a pretty slick logo in less than 5 minutes. I also decided to make the background a “tooltip” yellow, which I think looks really good.

Other than that everything is rather straight forward. We have checkboxes allowing the user to choose what events we will monitor. And we have a menu with a couple options, namely About and Exit. There is a “Clear Alerts” menu item, as well, that allows users to acknowledge they have responded to the alert(s).

The application allows user to select the number of minutes between alerts up to 60 minutes.

Of course we are using the State and Notification Broker to make all this happen. Using it means we hardly have to write any code ourselves!

State and Notification Broker setup code

   1: SystemState phoneMissedCalls = new SystemState(SystemProperty.PhoneMissedCalls);
   2: SystemState messagingSmsUnread = new SystemState(SystemProperty.MessagingSmsUnread);
   3: SystemState messagingTotalEmailUnread = new SystemState(SystemProperty.MessagingTotalEmailUnread);
   4: SystemState messagingVoiceMailTotalUnread = new SystemState(SystemProperty.MessagingVoiceMailTotalUnread);
   5:  
   6: private void frmMain_Load(object sender, EventArgs e)
   7: {
   8:     phoneMissedCalls.Changed += new ChangeEventHandler(phoneMissedCalls_Changed);
   9:     messagingSmsUnread.Changed += new ChangeEventHandler(messagingSmsUnread_Changed);
  10:     messagingTotalEmailUnread.Changed += new ChangeEventHandler(messagingTotalEmailUnread_Changed);
  11:     messagingVoiceMailTotalUnread.Changed += new ChangeEventHandler(messagingVoiceMailTotalUnread_Changed);
  12: }

 

The way we alert a user to having missed a monitored event is by playing a sounds which is easy to do.

   1: [DllImport("aygshell.dll")]
   2: static extern uint SndPlaySync(string pszSoundFile, uint dwFlags);
   3:  
   4: void PlaySound()
   5: {
   6:     string path;
   7:     path = Path.GetDirectoryName(Assembly.GetExecutingAssembly().GetName().CodeBase);
   8:  
   9:     SndPlaySync(Path.Combine(path, "alert.wma"), 0);
  10: }

Other than a little plumbing to make everything work together that is basically the entire app in a nutshell.

Possibilities:

This is a pretty spiffy application. But software can always be better. An option to allow the phone to vibrate would be great. Another option to allow the user to select the alert sound would be nice too.

4 Days left…

Today on twitter, Glen Gordon was telling me that Brendon Schwartz had an idea for today’s application:

glengordon @cjcraft here's an idea for a mobile app that @brendonschwartz will like - record $ spent during the day and where it was spent (with GPS) about 13 hours ago from Witty in reply to CJCraft

It’s a really good idea. Probably a better idea than we will be able to do it tonight, but we are all about taking the first small steps to accomplishing great things.

 

image

GeoCash

I love the name, it is a play on GeoCaching. Somehow it adds a lot of “buzz” to the application already.

The application is designed to be easy for the user to use and understand. The user only needs to enter the amount they spent along with a note, and then simply press log and it will be added to the GeoCash log.

We are using our own NumericTextBox to be sure the user doesn’t enter in any invalid amounts spent. We have another standard TextBox for the note input. Below this we have the log information. This is done using a WebBrowser control, and setting its DocumentText property.

The main reason to use the WebBrowser control is to be able to do a little better text formatting. This allowed us to easily markup our text in bold and color.

 

HTML formatted output:

   1: sb.AppendFormat(@"<b>Date:</b> {0}", DateTime.Now).Append("<br/>");
   2: sb.AppendFormat(@"<b>Amount:</b> <span style=""color:red"">{0:c}</span>", decimal.Parse(textBoxAmountSpent.Text)).Append("<br/>");
   3: sb.AppendFormat(@"<b>Note:</b> {0}", textBoxNote.Text).Append("<br/>");

Possibilities:

I love this app. It has so many cool possibilities. You could easily save this information to a text file or sent it as an email. I think this is perfect data to do a mashup on for example create a heatmap etc for it so you can see the “dangerous” side of town you need to avoid taking your money into from now on. Open-mouthed

5 Days Left…

So when you are talking Windows Mobile Applications you are usually talking about a cell phone device. We have looked at text messages using SMS, but one thing we haven’t look at so far is programmatically making phone calls. Today we will take a look at creating our own phone dialer application. It’s easier than you think!

I think the UI is pretty nice, not the best, but good overall. It is bright and clean. I found a web site that allowed me to create buttons in a snap and used it for the numbers. At the top of the screen, I added a label to display the number to dial. The menu only has a few options: Dial, Menu, Clear, About, and Exit.

Since we only allow users to enter numbers using our custom buttons, we don’t have to worry about anyone entering invalid characters.

So how much code did we as Windows Mobile application developers have to write to actually dial a number? See for yourself.

   1: private void Dial()
   2: {
   3:     new Phone().Talk(labelPhoneNumber.Text);
   4: }

Possibilities:

I think this has the potential to be an absolutely great application. One thing I think would be cool is if the application supported skinning. In a way it does, since I decided to leave the image resources as external files to the executable. So a user could edit any of the files themselves. Another great enhancement would be to have mousedown images for each button to give a nice “animated” touch to the application. What about quick soft sounds for when each button is pressed?
