MessageDlg, showmessage - both crash after 2.0 update?!

[JernejL]

This is on win32, and was working fine until i updated lazarus to 2.0, the project was converted from delphi in past, if that matters.

I cannot explain this, it stopped working only in 1 project, and not in others..

What kind of image are you loading/streaming? Make sure that it is in correct format (as in the stream).

[JernejL]

That image is loaded via vampyre library on my side and is not the cause of any issues, the crash happens in dialogs functions, and regardless from where i call them.
 
A simple call to showmessage('test') causes that crash - anywhere from my app.
 

[JernejL]

For the record, this was caused by not including dialogs and messages unit at correct place and / or order. As for why this broke after updating lazarus - i have no idea.
 

[ASBzone]

What version of Lazarus were you running before, and what was the order that had to be changed with the units?
