ActiveX Barcode Control Produces Invalid Metafile when Initially Called Using Windows 2000 with Service Pack 3
Calling the SaveEnhWMF method of the barcode control in Windows 2000 with Service Pack 3 can create an invalid and completely black image when the metafile is generated for the first time, due in part to a difference in the way the metafile is being initialized.
The pixel width and height of the metafile can be
initialized before saving the image. To do this, call the SetPixelsXY function before calling SaveEnhWMF. Here is an example:
SetPixelsXY 250, 250
where 250 is the height and width in pixels of the image to be saved.
