Doesn't anybody know? CBEM_SETIMAGELIST and SendMessage problems

[dubae524]

I guess I need to be more descriptive. I am using mainly the SendMessage API function and the CBEM_SETIMAGELIST constant in order to attach an ImageList to my API-created ComboBoxEx (aka "ImageCombo") control. Here are the declarations:


Declare Function SendMessage Lib "user32" Alias "SendMessageA" _
(ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, _
lParam As Any) As Long

WM_USER = &H400
CBEM_SETIMAGELIST = (WM_USER + 1)

ImgList is the ImageList, and CmboEx is the ComboBoxEx (aka "ImageCombo") handler. Here is the code:


SendMessage CmboEx, CBEM_SETIMAGELIST, 0, ImgList

Can somebody please tell me what I am doing wrong? I am just having a hard time figuring it out!

Doesn't anybody know how to answer my question?

Is ImgList an ImageList from the Common Controls OCX, or one that you created through the API?
If you created it with the API then I don't see a problem with your code, but if it's from the OCX, you'll need to do this:
SendMessage CmboEx, CBEM_SETIMAGELIST, 0, ByVal ImgList.hImageList

Hope this helps :rolleyes:

Oh wait, one more thing that I just noticed:
You said that CBEM_SETIMAGELIST = (WM_USER + 1)... Well, it should be WM_USER + 2.
Oh well :rolleyes:
