Using the InkPicture Control

[akenty]

I have a PowerBuilder 8.0 application which requires capturing a client's signature. How do I copy a signature (drawing) to the clipboard when using the Microsoft InkPicture control? I have placed the OLE control on my window and I am able to scratch a signature into the control, but I am not able to pass the signature to the clipboard. I've gone through the clipboard example in the MS Tablet PC SDK and found the ClipboardCopy command, but I get a Null Object reference when trying to run the following:


ole_1.object.Ink.ClipboardCopy(ls_null,14,1)

arguments are:
ls_null - if null, copies all the ink
14 - .EMF format (found w/ msgbox when running example)
0 - clipboard mode(found w/ msgbox when running example)

Any help would be greatly appreciated.
Thanks in advance
Andy

It looks like your trouble is in the Is_Null statment.

Try replacing it with the word "Nothing", or just leave it blank.

One of these two options should solve your trouble.

Hope this helps!
