Bonjour

Je travaille avec Excel 2003

J'ecris une macro qui lance un programme externe (avec la commande Shell).
Le programme effectue une tache, puis termine son execution.
La macro a besoin de savoir quand ce programme a termine

Comment faire pour tester si le programme est toujours en cours d'execution ?

Merci de votre aide

Jerome

Bonjour,

Il existe une API qui te permet de faire ca sans trop d'effort

Tout d'abord tu copies ce code dans un module

Code :

    End With
    If ShellExecuteEx(lpShellExInfo) Then
        Do While WaitForSingleObject(lpShellExInfo.hProcess, vnTimeOut) = WAIT_TIMEOUT
            DoEvents
        Loop
        GetExitCodeProcess lpShellExInfo.hProcess, ShellWait
        CloseHandle lpShellExInfo.hProcess
    Else
        ShellWait = vbError
    End If
End Function

Et tu utilises en appelant la fonction

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

ShellWait "toto.exe"
