Hi. I want to use VB.net to execute a program (*.exe file), wait till it finishes and get the return value the *.exe program returns. Now I did accomplish this using the code bellow however the error code i get the first few tries is correct but then i keep getting 0xCDCDCDCD as the error code. I don't understand why running this code would generate the wrong result after few tries. Please help.
How can i ensure i get the correct exit code
Ps. the *.exe file was writen in c++ and it always returns a positive integer where as 0xCDCDCDCD is negative as a signed integer representation

CODE:
VB
Dim startInfo As New System.Diagnostics.ProcessStartInfo
Dim MyProces As Process

startInfo.FileName = myExeFileName
startInfo.Arguments = myExeArgString
startInfo.CreateNoWindow = True
startInfo.UseShellExecute = True
startInfo.WindowStyle = ProcessWindowStyle.Hidden

MyProces = Process.Start(startInfo)
MyProces.WaitForExit()

If (MyProces.ExitCode <> 0) Then
  MsgBox("0x" + Hex(MyProces.ExitCode()))
End If

The Process class has an ExitCode property. Example here[^].

I think that is what you need. :)
