VB 6: Comment puis-je exécuter une .le fichier bat, mais attendre jusqu'à ce que sa fait courir avant de passer?

Vous aurez besoin d'utiliser l'API Win32 appels à ShellExecuteEx et WaitForSingleObject sur le handle de processus renvoyé de ShellExecuteEx dans le SHELLEXECUTEINFO structure. C'est un vieux code que j'ai tiré d'un projet. C'est en travaillant à 100%, mais je ne peut pas avoir inclus toutes les dépendances. Vous devriez être en mesure de modifier vos exigences:

      Type SHELLEXECUTEINFO
cbSize As Long
fMask As Long
hwnd As Long
lpVerb As String
lpFile As String
lpParameters As String
lpDirectory As String
nShow As Long
hInstApp As Long
'  Optional fields'
lpIDList As Long
lpClass As String
hkeyClass As Long
dwHotKey As Long
hIcon As Long
hProcess As Long
End Type
Public Declare Function ShellExecuteEx Lib "shell32.dll" 
(lpExecInfo As SHELLEXECUTEINFO) As Long
Public Declare Function apiShellExecute Lib "shell32.dll" _
Alias "ShellExecuteA" _
(ByVal hwnd As Long, _
ByVal lpOperation As String, _
ByVal lpFile As String, _
ByVal lpParameters As String, _
ByVal lpDirectory As String, _
ByVal nShowCmd As Long) _
As Long
Declare Function WaitForSingleObject Lib "kernel32" 
(ByVal hHandle As Long, ByVal dwMilliseconds As Long) As Long
Public Const SEE_MASK_NOCLOSEPROCESS As Long = &H40
Public Const SEE_MASK_FLAG_DDEWAIT As Long = &H100
'***App Window Constants***'
Public Const WIN_NORMAL = 1         'Open Normal'
Public Const WIN_MAX = 2            'Open Maximized'
Public Const WIN_MIN = 3            'Open Minimized'
'***Error Codes***'
Private Const ERROR_SUCCESS = 32&
Private Const ERROR_NO_ASSOC = 31&
Private Const ERROR_OUT_OF_MEM = 0&
Private Const ERROR_FILE_NOT_FOUND = 2&
Private Const ERROR_PATH_NOT_FOUND = 3&
Private Const ERROR_BAD_FORMAT = 11&
' Returns 'True' if file was opened ...'
Public Function fHandleFile(ByVal stFile As String, _
ByVal lShowHow As Long, _
ByRef stRet As String, _
Optional ByVal bWaitForClose As Boolean = False) As Boolean
On Error GoTo err_Handler
Dim lRet As Long
Dim ret As Long
Dim lngProcessHandle As Long
Dim varTaskID As Variant
Dim shInfo As SHELLEXECUTEINFO
Dim retval As Long
'First try ShellExecute'
With shInfo
.cbSize = LenB(shInfo)
.lpFile = stFile
.nShow = lShowHow
If bWaitForClose Then
.fMask = SEE_MASK_FLAG_DDEWAIT + SEE_MASK_NOCLOSEPROCESS
End If
.lpVerb = "open"
End With
Call ShellExecuteEx(shInfo)
lRet = shInfo.hInstApp
If lRet > ERROR_SUCCESS And bWaitForClose = True Then
lngProcessHandle = shInfo.hProcess
Do
retval = WaitForSingleObject(lngProcessHandle, 0)
DoEvents
Loop Until retval <> 258
ret = CloseHandle(lngProcessHandle)
End If
fHandleFile = (lRet > 0)
exit_handler:
Exit Function
err_Handler:
RaiseError Err.Number, Err.Source, Err.Description
End Function
