VBA - shell

[jammiedude]

Hello, if anyone can help with this I would much appreciate it.

I am writing a macro within vba for excel, and i have successfully managed to use the shell command to call my batch file but, how would i program the rest of the macro to carry on when the batch file has finished?

The batch file currently has a pause at the bottom, but i removed this and the batch file just ended when finished would i be able to somehow use vba to check to see if the batch file is still running or something?

Thanks

using DOEVENTS just might help you .

Hello, many thanks for the reply i managed to find a function on the net, that was able to lock into a loop until the process was finished. which is:

Option Explicit

      Private Type STARTUPINFO
         cb As Long
         lpReserved As String
         lpDesktop As String
         lpTitle As String
         dwX As Long
         dwY As Long
         dwXSize As Long
         dwYSize As Long
         dwXCountChars As Long
         dwYCountChars As Long
         dwFillAttribute As Long
         dwFlags As Long
         wShowWindow As Integer
         cbReserved2 As Integer
         lpReserved2 As Long
         hStdInput As Long
         hStdOutput As Long
         hStdError As Long
      End Type

      Private Type PROCESS_INFORMATION
         hProcess As Long
         hThread As Long
         dwProcessID As Long
         dwThreadID As Long
      End Type

      Private Declare Function WaitForSingleObject Lib "kernel32" (ByVal _
         hHandle As Long, ByVal dwMilliseconds As Long) As Long

      Private Declare Function CreateProcessA Lib "kernel32" (ByVal _
         lpApplicationName As Long, ByVal lpCommandLine As String, ByVal _
         lpProcessAttributes As Long, ByVal lpThreadAttributes As Long, _
         ByVal bInheritHandles As Long, ByVal dwCreationFlags As Long, _
         ByVal lpEnvironment As Long, ByVal lpCurrentDirectory As Long, _
         lpStartupInfo As STARTUPINFO, lpProcessInformation As _
         PROCESS_INFORMATION) As Long

      Private Declare Function CloseHandle Lib "kernel32" (ByVal _
         hObject As Long) As Long

      Private Const NORMAL_PRIORITY_CLASS = &H20&
      Private Const INFINITE = -1&

    Public Sub ExecCmd(cmdline$)
         Dim proc As PROCESS_INFORMATION
         Dim start As STARTUPINFO
         Dim ReturnValue As Integer

         ' Initialize the STARTUPINFO structure:
         start.cb = Len(start)

         ' Start the shelled application:
         ReturnValue = CreateProcessA(0&, cmdline$, 0&, 0&, 1&, _
            NORMAL_PRIORITY_CLASS, 0&, 0&, start, proc)

         ' Wait for the shelled application to finish:
         Do
            ReturnValue = WaitForSingleObject(proc.hProcess, 0)
            DoEvents
            Loop Until ReturnValue <> 258

         ReturnValue = CloseHandle(proc.hProcess)
      End Sub

Then all you do is call cmdline$ " " and pass the batch file location in the commas.

Many thanks!
