ID's ???

Hey!

How can I know when a Ms-DOS Application launch in by the shell command is done? In this example, I want the program PURGE accomplich is job then the will complete the FOR...NEXT instructions.

Ex:

[CODE]
Private sub CmdOk_Click()
for i = 0 to list1.listcount - 1
cmd$ = "PURGE /DATA "+chr$(34)+list1.list(i)+chr$(34)
shell cmd, vbhide
next i
msgbox "Done.", vbinformations
end sub

Try something like this:

Code:

---

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
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
Declare Function CloseHandle Lib "kernel32" (ByVal hObject As Long) As Long
Private Const NORMAL_PRIORITY_CLASS = &H20&
Private Const INFINITE = -1

Public Sub ExecuteCommandLine(p_strCommandLine As String)
    Dim tProcInfo As PROCESS_INFORMATION
    Dim tStartInfo As STARTUPINFO
    Dim lngRet As Long
   
    tStartInfo.cb = Len(start)

    lngRet = CreateProcessA(0&, p_strCommandLine, 0&, 0&, 1&, NORMAL_PRIORITY_CLASS, 0&, 0&, tStartInfo, tProcInfo)

    'Wait while the shelled application is finished
    lngRet = WaitForSingleObject(tProcInfo.hProcess, INFINITE)
    lngRet = CloseHandle(tProcInfo.hProcess)
End Sub

Then you can use this sub routine like this:

Code:

---

Private Sub Command1_Click()
    Dim i As Integer
    Dim strCommandLine As String
   
    For i = 0 To List1.ListCount - 1
        strCommandLine = "PURGE /DATA " + Chr(34) + List1.List(i) + Chr(34)
        ExecuteCommandLine strCommandLine
    Next
    MsgBox "Done.", vbinformations
End Sub
