Nix avait expliqué comment déclencher un programme DOS (Rubrique Shell : Envoyer une commande DOS). Voici la même chose, mais en beaucoup plus compliqué (et un peu plus puissant...).
Créez un fichier format texte, mettez le code dedans puis renommez le fichier en Form1.frm Ouvrez form1.frm avec VB 5 ou VB 6, sous 95 ou 98 (devrait pas avoir de problème en NT)... et cliquez.
Trouvez à quoi ca sert et me prévenir....
Source / Exemple :
VERSION 5.00
Begin VB.Form Form1
Caption = "Form1"
ClientHeight = 975
ClientLeft = 60
ClientTop = 345
ClientWidth = 3585
LinkTopic = "Form1"
ScaleHeight = 975
ScaleWidth = 3585
StartUpPosition = 3 'Windows Default
Begin VB.CommandButton Command1
Caption = "C'est parti !"
Height = 495
Left = 1200
TabIndex = 0
Top = 240
Width = 1215
End
End
Attribute VB_Name = "Form1"
Attribute VB_GlobalNameSpace = False
Attribute VB_Creatable = False
Attribute VB_PredeclaredId = True
Attribute VB_Exposed = False
Option Explicit
Private Declare Function AllocConsole Lib "kernel32" () As Long
Private Declare Function GetStdHandle Lib "kernel32" (ByVal nStdHandle As Long) As Long
Private Declare Function WriteConsole Lib "kernel32" Alias "WriteConsoleA" (ByVal hConsoleOutput As Long, ByVal lpBuffer As String, ByVal nNumberOfCharsToWrite As Long, lpNumberOfCharsWritten As Long, lpReserved As Any) As Long
Private Declare Function CloseHandle Lib "kernel32" (ByVal hObject As Long) As Long
Private Declare Function FreeConsole Lib "kernel32" () As Long
Private Const STD_OUTPUT_HANDLE = -11&
Private hConsole As Long
Private Sub Command1_Click()
'*** Pour lancer un application appelée Text.exe ou test.bat, par exemple
Dim app_name As String
Dim txt As String
Dim num_written As Long
app_name = App.Path
If Right$(app_name, 1) <> "\" Then app_name = app_name & "\"
app_name = app_name & "test.bat"
txt = "Alors, on y va ?" & vbCrLf
WriteConsole hConsole, txt, Len(txt), num_written, vbNullString
'enlever le commentaire à la suite pour lancer l'application....
'Shell app_name
End Sub
Private Sub Form_Load()
Dim txt As String
Dim num_written As Long
If AllocConsole() Then
hConsole = GetStdHandle(STD_OUTPUT_HANDLE)
If hConsole = 0 Then MsgBox "Impossible d'allouer STDOUT"
' Par sécurité, pour les neuneus....
txt = "***********************************************" & vbCrLf & _
"* Attention, fermer l'appli VB en premier *" & vbCrLf & _
"***********************************************" & vbCrLf
WriteConsole hConsole, txt, Len(txt), num_written, vbNullString
' Rend l'appli visible, au premier plan....
Me.Show
SetFocus
Else
MsgBox "Impossible d'allouer STDOUT"
End If
End Sub
Private Sub Form_Unload(Cancel As Integer)
CloseHandle hConsole
FreeConsole
End Sub
Conclusion :
Créez un fichier format texte, mettez le code dedans puis renommez le fichier en Form1.frm Ouvrez form1.frm avec VB 5 ou VB 6, sous 95 ou 98 (devrait pas avoir de problème en NT)... et cliquez.
