RichEdit OLE callback demo
« on: July 05, 2013, 05:31:23 PM »
Here is simple richedit test with OLE callback for showing pictures too.
Please inform if you find errors.

EDIT: fix pointer passing

Don't know if it is a bug or a feature, that a RETURN inserts a new row.

That's richedit feature.
There is still bug in pointer passing too.

Crashes on exit at 0x74dcc3a8 (Win XP SP3).
The instruction is call [ecx+8], and ecx=0.
Program terminates normally when the call [ecx+8] is disabled (but attention, there is a push eax before).

Otherwise a great demo - thumbs up 8)

Return inserts a paragraph (aka CrLf or \par in RTF speak),
Shift Return inserts a line break (\line in RTF).

However, you can see it only when you save as RTF and then reopen in a plain text editor like Notepad.

That's what I mean: Return should insert a line break (\par in RTF speak) but it inserts a new row.

here is small test program to show rtf code too.
BTW: inside table it insert new table row and outside just new line

Technically, the rich edit control should just advance to the next line then if a character key is pressed then /par else if enter is pressed again /line. The rich edit control is poorly designed not buggy just like the text edit control for notepad has odd behaviors when strings contain certain chars like $.

That's my two non-cents ;-)

Good stuff though and good feedback.
