.net - Multiple Notification Icons Appear When Using Multithreading
May 13, 2011
Context: I'm working with a relatively simple winforms application, written in VB.NET on the .NET 3.5 framework in Visual Studio 2010. Issue: The FormLoad event creates two threads when the program is opened. One handles automatic update checking and the other performs a time consuming task syncing files with the internet. These threads are initialized as follows:

I've got a timer which ticks every half a second. It calls a background process which renders text as icons and uses them for notification icons.
Public Shared DISCUS(9) As NotifyIcon
Private Sub BackgroundProcess2_DoWork() Handles BackgroundProcess2.DoWork
Try
For counter As Integer = 0 To My.Computer.FileSystem.Drives.Count - 1
Dim FontColor As Color
[Code] .....
Now for some reason, after a few minutes of the application being active, I get a JIT pop-up that doesn't render any text or buttons. Clicking on it causes the JIT debugger to crash, and I get the Windows "{App} has stopped responding." with error code CLR20R3. I'm not sure what this is all about, but I can provide any other details if needed. I've got everything nested in Try/Catch statements, all with code to write to a crash log but nothing gets written and I still get that error message.

I'm trying to write a very basic program in VS 2008 (VB.NET 2.0) that will help me to quickly set up new servers. One of the things I want the program to do is hide the "Volume" and "Network" system icons. I cannot find where that setting is or a way to programmically change it.

My question is, imagine I have two List(Of T) objects and a subroutine in a multithreaded environment that modifies both of these objects. I don't understand locks very well, so I'm unsure whether I can just do:
SyncLock CType(List1, IList).SyncRoot
List1.Clear()
List2.Clear()

I have one Private sub that runs in a loop. I want the sub to run multiple times at once. For example the program runs, you press start; you run the program again and press start, again and again... the same program doing the job at once. now i just want one program do to it alone. But i would like it to be user defined. exp. run program. type in a text box 10. press start. and it works as if 10 of them work open working on the same thing.

I'm trying to embed 3 icons into a VB .NET exe. After searching for a number of hours, I ended up using this page as a guide. I made a .res file with my icons. But I cannot, for the life of me, find how to to import that .res file into my project using the IDE. The above mentioned guide mentions something about that, but no "Resources" group box is available in the Application tab of the properties Page of the project.
After more searching, it seems that the only way a .res file can be imported is by using the /win32resource compiler switch. I can use that switch only if I use the command line to compile my project. Is there any way I can add that extra compiler switch in the IDE, so that every time I compile, the .res file is automatically imported? I'm using VB in VS 2008.

I've always had to use a program that does this stuff for me, but I'd like to just make my own program that does this. I've already got the individual bitmap images of the 3 sizes (16x16, 32x32 and 48x48) for the icon file and I usually find use some shareware program to create the icon file from the multiple bitmap images for me but I'm wondering if it's possible in .Net to create an icon file (*.ico) that contains multiple physical icons in it.

I'm sick of my EXE files only looking decent in one view in explorer (ie List or Tiles etc) because I can only figure out how to specify one icon file for my projects so it has to be a specific size and if its too big it looks rubbish at smaller sizes in explorer, and vice versa if its too small. So how can I embed more than one icon file and make it automatically select the correct one to display in explorer depending on the view? I believe you can store more than one icon in an ICO file, so do you have to just combine the various size icons into one ICO and then explorer will automatically select the correct sized on? Or is it something you have to do within the VB project?

TortoiseSVN and Dropbox both have Windows shell extensions that make file icons within Windows Explorer show a small icon beside the main one, showing the file's status - has it been synced, etc How can I make my application show icons beside files like that using the Windows API? Or is there some file attribute to do that?

I just had a new, last-minute idea on to take on a task, so I am running to StackExchange for quick help.
What I want to do is execute a series of methods right in a row, each in their own threads. I want the application to wait until all of these threads are completed, after which the program will resume. It also has to use managed threading (thread pool).
What quick examples could you provide to help me along the way? If it's too complex, what things should I know about so that I can Google it on my own?

I have multiple control in the form. 10+ textboxes, 2 comboboxes. These controls will change their back color when get focus. I don't want to use control arrays and I don't want to write in multiple GotFocus/LostFocus. The only idea I have is, checking wheather Me.ActiveControl has changed or not from a timer.

Im using the InstanceCreationEvent of Win32_PrintJobI'm getting some rather unusual results.Sometimes I get notification of the print job and a correct number of pages printed.
