Hi ,

Can we call a Shell Script through BO? If so can anyone please tell me how that can be done.

Thanks

here is a snippet of code that we use to execute a shell script. We call the process from within our code as follows:

StartProcess “C:\MyBatchFile.bat”, True



Public Type PROCESS_INFORMATION
    hProcess    As Long
    hThread     As Long
    dwProcessID As Long
    dwThreadID  As Long
End Type
Public Type STARTUPINFO
    cb              As Long
    lpReserved      As Long
    lpDesktop       As Long
    lpTitle         As Long
    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
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

Public Sub StartProcess(CommandLine As String, Optional Hide As Boolean = False)
    Const STARTF_USESHOWWINDOW As Long = &H1
    Const SW_HIDE As Long = 0
    
    
    Dim proc As PROCESS_INFORMATION
    Dim Start As STARTUPINFO

    'Initialize the STARTUPINFO structure:
    Start.cb = Len(Start)
    If Hide Then
        Start.dwFlags = STARTF_USESHOWWINDOW
        Start.wShowWindow = SW_HIDE
    End If
    'Start the shelled application:
    CreateProcessA 0&, CommandLine, 0&, 0&, 1&, _
        NORMAL_PRIORITY_CLASS, 0&, 0&, Start, proc

End Sub

Let me know if you run into any runtime errors, as I simply cut and pasted from a much larger process, so I might have inadvertently left something out.
