VBA problem in running .bat file

[sophannaly]

Hi,

I do have problem with running .bat file in vba. The problem is if I run .bat file directly(not via vba), I will get the correct result. If I run in debug mode, I will get the correct result as directly run .bat file too. But if I run it from vba, then I will get the incorrect result. Below is my code about how I call my bat file and its function:

FileName = CurrentProject.Path & "\Request_Budget_Expenditure\Request_Budget_Expenditure_run.bat"
        Call WaitResponse.ShellWait(FileName, 1)

Function definition:

'This module is about run .bat file and then wait for program to finish running
 
Private Const STARTF_USESHOWWINDOW& = &H1
Private Const NORMAL_PRIORITY_CLASS = &H20&
Private Const INFINITE = -1&
 
 
Private Type STARTUPINFO
    cb As Long
    lpReserved As String
    lpDesktop As String
    lpTitle As String
    dwX As Long
    dwY As Long

    lpStartupInfo As STARTUPINFO, lpProcessInformation As _
    PROCESS_INFORMATION) As Long
 
Private Declare Function CloseHandle Lib "kernel32" (ByVal _
    hObject As Long) As Long
 
 
' To run .bat file and until that program finish running
 
Public Sub ShellWait(Pathname As String, Optional WindowStyle As Long)
    Dim proc As PROCESS_INFORMATION
    Dim start As STARTUPINFO
    Dim ret As Long
    ' Initialize the STARTUPINFO structure:
    With start
        .cb = Len(start)
        If Not IsMissing(WindowStyle) Then
            .dwFlags = STARTF_USESHOWWINDOW
            .wShowWindow = WindowStyle
        End If
    End With
    ' Start the shelled application:
    ret& = CreateProcessA(0&, Pathname, 0&, 0&, 1&, _
            NORMAL_PRIORITY_CLASS, 0&, 0&, start, proc)
    ' Wait for the shelled application to finish:
    ret& = WaitForSingleObject(proc.hProcess, INFINITE)
    ret& = CloseHandle(proc.hProcess)
End Sub
'***************** Code End ****************
 
 
 
 
 

I already tested it many times, and I just have no idea why the same program but different result between run in debug mode and run mode.
Please tell me how do solve about this problem.

Best regards,

Hi,

I found solution but i'm not sure is it like that but it works for me. I think this problem is about running speed update to table and upload these data to remote DB via bat file.So I have please a pop up message between these two functions as

strSQL = "UPDATE request_expenditure SET revision=" & old_revision
        db.Execute strSQL, dbFailOnError
 
        MsgBox db.RecordsAffected & " record(s) affected."
 
        FileName = CurrentProject.Path & "\Request_Budget_Expenditure\Request_Budget_Expenditure_run.bat"
        'Call ShellWait(FileName)
        Call waitfiletorun.ShellWait(FileName)
