• Visual C# running two thread

  Hi. I need a sample code for running two threads simultaniously that each of threads fill own progress bar Here is a little self-explaining example: private void button1_Click( object sender, System.EventArgs e) { Thread thread1 = new Thread( new ThreadStart(FillProgressBar1)); Thread thread2 = new Thread( new ThreadStart(FillProgressBar2)); thread1.Start(); thread2.Start(); } private void FillProgressBar1() { while ( progressBar1.Value < progressBar1.Maximum ) { progressBar1.Value++; Thread.Sleep( 100 ); } } private void FillProgressBar2() { while ( progressBar2.Value < progressBar2.Maximum ) { ...Show All

• SQL Server ODBC & Multi-threading

  I'm working on a C# (2005) app that requires shooting a large number of queries via Odbc, wait until the last one is done and then compute an overall result. Since the queries are not interdependent, I would like to get them to run concurrently on multiple threads. I did manage to get several queries run on different threads but the response time for the same query varies dramatically when another query is running concurently (even on a different ODBC connection). All is as if something was queing those queries regardless of the threads and/or the connection objects being used. Basically when I run a very simple query q1 (thread 1 c ...Show All

• Visual C# Printing 'this' form...

  OK, I surrender... What I want to do is simply print the form (actually, the tabPage) that's currently active, just the way it looks on the screen. I've gotten into a lot of circular logic with DrawToBitmap and ...Bounds( ) and I'm sure there must be an easier way. If anyone can show me how to do this with a few lines of code, I'd be eteranlly grateful... Thanks in advance for any and all help! John F. There's a great example with code for printing the form here, in case anyone else has the some question: http://whidbey.msdn.microsoft.com/library/default.asp url=/library/en-us/dv_csexpresscon/html/831ef528-7 ...Show All

• Windows Forms LIB's in a Windows Form?

  Hi folks, I'm just wondering if it's possible to add a LIB to a Windows Form project I want to add Shlwapi.h, shlwapi.lib so that I can access the useful functions: PathAddBackslash PathIsDirectory PathRemoveFileSpec PathRemoveBackslash PathFileExists PathFindFileName etc....

• Visual C# Jagged Array and GetType()

  Hi all, I see something odd when I call GetType() on a jagged array where one of the sub-arrays is multi-dimensional. Please look at this code and think about what you expect it to produce: int[][,] x = new int[3][,]; Console.WriteLine(x.GetType()); It's just that the CLR type name uses a different ordering. If you ildasm your code, you'll see that ordering is the same as the one produced by GetType. In a way, it makes more sense the CLR way. If you think of it as: Array of... Multidimensional arrays of... Int32 Then the most strictly logical orderings would be [][,]int or (as the CLR uses it) int[,][], depending on whether you w ...Show All
