Title: Access Violation in comctl32.dll
Post by: John H. on August 05, 2009, 02:53:23 AM
I have Qimage v2009.267 running on Win XP SP3 with 1.5GB of ram.  When I right click on a directory in the folder window I get the following error message:

Access violation at address 5D098019 in module comctl32.dll.  Write of address 00000000.

When I click OK the Windows right-click menu shows.  Is this a Qimage or Windows dll issue.  It does not happen within Windows Explorer.

Thanks.
John

That is strictly a Windows error as right clicking on a folder calls the standard browse-for-folder context dialog.  Your comctl32.dll may be corrupted, you may have a virus, or your virus scanning software may be preventing the popup.  You'll likely get the same error in any other program that allows you to browse for folders.  You won't see the behavior in Explorer because Explorer doesn't browse for folders: it browses for files and folders.

I'm was leaning towards the corrupted file also.  However, I've tried a half dozen other programs that display a folder window such as Qimage and have no issues.  I'll keep digging.  Something somewhere isn't playing nice.

Because they display folders does not mean they are folder browsing windows.  You have to find an application that uses the browse-for-folder dialog (where you can pick folders only: no files) and one that also allows the full context menu on right click.  I can't find any.  IE has a simple browse for folder dialog but right click does nothing: no context menu hooked up.  FireFox looks like it has one: click tools, then on the main tab click "Downloads", "Save Files To" and click "Browse".  That browse for folder window appears to have a right click context menu.  See if that one works.  Of course, even if it does, it doesn't really prove anything.  The browse-for-folder dialogs have quite a number of options that can be used as does the context menu.  Qimage may be using different options that invoke the bug on your system.
