Hi Dylan, I wonder if you might be able to shed insight into this. cryptui uses riched20 to display some text, and inserting an icon into a richedit control causes a crash:
Assertion failed: (~para->member.para.nFlags & MEPF_REWRAP), function ME_GetCursorCoordinates, file caret.c, line 183.
If I comment out the assertion, the icon gets displayed, a little offset from where I expected it, but no other crashes appear.
I'm inserting the icon with: IRichEditOle_InsertObject(richEditOle, &reObject); (in cryptui's main.c.)
The call stack isn't all that interesting, so I followed the call flow a little by hand.
IRichEditOle_InsertObject is a wrapper that calls IRichEditOle_fnInsertObject. This calls ME_InsertOLEFromCursor, which calls ME_InternalInsertTextFromCursor. This calls ME_InsertRunAtCursor. ME_InsertRunAtCursor sets the MEPF_REWRAP flag: cursor->pPara->member.para.nFlags |= MEPF_REWRAP; which, I believe, is what leads to the assertion.
Might you shed some insight into what the assertion is protecting against, or better yet how I might avoid it?
If you have any interest in looking at it, I can send you a small .c file with instructions on how to reproduce the crash.
Thanks, --Juan
