[Qt-interest] Generating application icons with Windows, Qt 4.7.1 and Visual Studio Addin 1.1.7

[Jason H]

I'm betting you just didn't do a "rebuild all". I get burned by it sometimes. 

Remember "make" isn't perfect - it just uses timestamps, not hashes.

Hi all,
 
I spent most of yesterday going round in circles trying to fix a problem, so 
thought I’d share it (and the solution) with you all.
 
I recently ported my application from building on Windows XP, Qt 4.6.3, to 
Windows 7, Qt 4.7.1.  I noticed recently that the application icon no longer 
appears in Explorer, or while the application is running.
 
I tried *many* things, of which I won’t go in to, but I finally decided to 
compare my vcproj file for the two versions.  And there was a very subtle 
difference.
 
In the qrc file, the *new* version had the following extra lines:
                                                                
<FileConfiguration
                                                                                
Name="Debug|Win32"
                                                                                
>
                                                                                
<Tool
                                                                                               
 Name="VCCLCompilerTool"
                                                                                               
 UsePrecompiledHeader="0"
                                                                                
/>
                                                                
</FileConfiguration>
                                                                
<FileConfiguration
                                                                                
Name="Release|Win32"
                                                                                
>
                                                                                
<Tool
                                                                                               
 Name="VCCLCompilerTool"
                                                                                               
 UsePrecompiledHeader="0"
                                                                                
/>
                                                                
</FileConfiguration>
 
When I removed these, delete the .exe, and re-generate the .exe.  The icon was 
there!
 
To make things even more confusing, if I put the lines back in, delete the .exe 
and re-generate, the icon is still there!  But at least it fixes my problem 
(albeit annoyingly).
 
Luckily I don’t have to re-generate too frequently.  But if anybody has seen a 
similar problem and has a better solution, that’d be great to see!
 
Darryl
