Zitat:

Ensuring Your Application Links to ComCtl32.dll If you provide a manifest, but your application does not link to ComCtl32.dll, then it will fail to load - sometimes with no error message!. You need to call at least InitCommonControls before any visual elements are displayed. Sometimes, you don't need to do anything because your application may already link to ComCtl32.dll (for example, if it includes any of the Windows Common Controls provided with Visual Basic), however, to be certain it works it is best to call InitCommonControls prior to displaying any forms. Here is the code you need at the start of your application to ensure you've linked to ComCtl32.dll: Private Type tagInitCommonControlsEx lngSize As Long lngICC As Long End Type Private Declare Function InitCommonControlsEx Lib "comctl32.dll" _ (iccex As tagInitCommonControlsEx) As Boolean Private Const ICC_USEREX_CLASSES = &H200   Public Function InitCommonControlsVB() As Boolean On Error Resume Next Dim iccex As tagInitCommonControlsEx ' Ensure CC available: With iccex .lngSize = LenB(iccex) .lngICC = ICC_USEREX_CLASSES End With InitCommonControlsEx iccex InitCommonControlsVB = (Err.Number = 0) On Error Goto 0 End Function   Public Sub Main() InitCommonControlsVB   ' Start your application here End Sub
