This article was previously published under Q78073 SYMPTOMS
If you use the Visual Basic LoadPicture function to load an icon
file (.ICO) into a picture control, and then attempt to copy that
picture control's picture to the Clipboard by using the SetData method,
the following error message is displayed regardless of the format
specified in SetData method:
Invalid Clipboard Format
This error also occurs if you attempt to load an icon file directly onto
the Clipboard by using this code:
ClipBoard.SetData LoadPicture("c:\vb\icons\arrows\arw01rt.ico")
CAUSE
The Microsoft Windows Clipboard in Windows has no CF_ICON format, so
the Clipboard cannot be assigned Icons.
STATUS
This behavior is by design in Microsoft Windows Clipboard.
WORKAROUND
To work around the problem, set the picture control's Autoredraw
property to True (-1) and use the Picture control's Image property in
the SetData method rather than the Picture control's picture property.
'*** This code will fail with the error "Invalid Clipboard Format" ***
Picture1.Picture = LoadPicture("c:\vb\icons\arrows\arw01rt.ico")
Clipboard.SetData Picture1.Picture, 2
'*** This code will avoid the error ***
Picture1.Autoredraw = -1
Picture1.Picture = LoadPicture("c:\vb\icons\arrows\arw01rt.ico")
Clipboard.SetData Picture1.Image, 2
'*** This code will also work ***
Picture1.Picture = LoadPicture("c:\vb\icons\arrows\arw01rt.ico")
Picture1.Picture = Picture1.Image
Clipboard.SetData Picture1.Picture, 2
