Botón de Minimizar en UserForm
Quiero agregar el botón de Minimizar a mi formulario, he intentado usar el siguiente código pero me causa errores en las macros que anteriormente tenia (error de compilación, no se ha definido la variable). Pero si no le pongo el código para el botón minimizar todo funciona bien.
¿Qué puedo corregir?
Este es código que uso actualmente para minimizar :
Option Explicit Private Declare PtrSafe Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As Long Private Declare PtrSafe Function DrawMenuBar Lib "user32" (ByVal hWnd As Long) As Long Private Declare PtrSafe Function SetWindowLong Lib "user32" Alias "SetWindowLongA" (ByVal hWnd As Long, ByVal nIndex As Long, ByVal dwNewLong As Long) As Long Private Declare PtrSafe Function GetWindowLong Lib "user32" Alias "GetWindowLongA" (ByVal hWnd As Long, ByVal nIndex As Long) As Long Private Const WS_MINIMIZEBOX As Long = &H20000 Private Const WS_MAXIMIZEBOX As Long = &H10000 Private Const GWL_STYLE As Long = (-16) Private Sub UserForm_Initialize() Dim lngMyHandle As Long, lngCurrentStyle As Long, lngNewStyle As Long If Application.Version < 9 Then lngMyHandle = FindWindow("THUNDERXFRAME", Me.Caption) Else lngMyHandle = FindWindow("THUNDERDFRAME", Me.Caption) End If lngCurrentStyle = GetWindowLong(lngMyHandle, GWL_STYLE) lngNewStyle = lngCurrentStyle Or WS_MINIMIZEBOX Or WS_MAXIMIZEBOX SetWindowLong lngMyHandle, GWL_STYLE, lngNewStyle End Sub
