التعامل مع برنامج أخر من خلال برنامجي

هذا يعتمد على نوع البرنامج الاخر

يجب استخدام هذه الدالات.. ساضع الكود لاحقا

Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As Long
Private Declare Function FindWindowEx Lib "user32" Alias "FindWindowExA" (ByVal hWnd1 As Long, ByVal hWnd2 As Long, ByVal lpsz1 As String, ByVal lpsz2 As String) As Long
Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long
Private Const WM_GETTEXT = &HD

هذا الكود كما قلت... لكن يجب عليك احضار ال ClassNames للبرنامج اذي تريد التعديل فيه باستخدام SPY++

Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As Long
Private Declare Function FindWindowEx Lib "user32" Alias "FindWindowExA" (ByVal hWnd1 As Long, ByVal hWnd2 As Long, ByVal lpsz1 As String, ByVal lpsz2 As String) As Long
Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal Hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long
Private Const WM_GETTEXT = &HD

Private Sub Form_Load()
Dim Hwnd As Long
Dim TextBox As Long
Dim sText As String
Dim RetVal As Long
Hwnd = FindWindow("ClassName", vbNullString)
If Hwnd <> 0 Then
    TextBox = FindWindowEx(Hwnd, 0&, "TextBoxClassName", vbNullString)
    RetVal = SendMessage(TextBox, WM_GETTEXT, 0, sText)
    MsgBox sText
End If
End Sub
