I'm having a particular problem that I need to resolve but can't seem to find the answer.
I have a Winform application that does various processes and spawns several threads to do various bits of work. On one of the threads it spawns another thread that in turn uses the Process.Start() method to start a new process (BCP in this case) to upload some data to SQL Server. Now... when I run this app from a console/command-line it works fine and no process gets hung. When it's run from the winform app it hangs on the Process.Start() method and doesn't return albeit the BCP executes and exits normally. I've examined the threads and the thread is in a sleep, wait, or join state. Here's a partial list of the thread call stack: [In a sleep, wait, or join] System.dll!System.Diagnostics.ShellExecuteHelper.ShellExecuteOnSTAThread() + 0x77 bytes System.dll!System.Diagnostics.Process.StartWithShellExecuteEx(System.Diagnostics.ProcessStartInfo startInfo) + 0x2d8 bytes System.dll!System.Diagnostics.Process.Start() + 0x80 bytes ... I do have a Process.WaitForExit() method call after the Process.Start() call but it never exits the Process.Start(). Here's my code that executes the process: Process p = new Process(); p.StartInfo.FileName = "bcp.exe"; p.StartInfo.WindowStyle = ProcessWindowStyle.Hidden; p.StartInfo.Arguments = arguments.ToString(); p.Start(); Any help would be most appreciated.
