GetOlePicture???... Help!!!
Hi there,
I am TRYING to write a DLL in D3 for use in a Visual Basic application.
what I want to do is load a Jpeg from disk and export it it to the Picture
Property of a VB pictureBox. For this I have done the following.. I load
the Jpeg in the dll and convert it to a bitmap.
Then I assign that bitmap to a var'ed IpictureDisp like this:
GetOlePicture(bitmap,Ipicturedisp);
and then use that Ipicturedisp for a return of the function. This compiles
without any errors. So then I go to VB and do the following:
Picture.picture=myfunction(somejpegfile)
This blows up every time with a GPF. I have put a showmessage in my
function and have determined that everything seems okay until I actually
assign the IpictureDisp to the return value.
Does anyone have an example of the GetOlePicture's usage, of if not.. a
suggestion on how to go about exporting a graphic from Delphi to VB?
Thanks in advance..
Dave
