Goody Gumdrops.
 
Just committed a change to CVS so that icons, bitmaps and cursors created in the standard way are first checked for in the EXE file that loaded Win32::GUI. Now there are some little points of note:
 
1. Doesnt work with PAR (unless you're a sneaky bugger). The reason it doesnt work with PAR is because PAR is just a self-extracting archive that auto-runs a perl interpreter on extraction. If you want to compile-in resources with PAR you'll need to add the resources to whatever interpreter executable it puts inside it's archive (looks like it's par.exe) rather than the exe file actually generated by PAR.
 
2. If I play around with perl2exe-generated executables in ResHacker, they either crash or fail to even start. This might be some sort of "don't you hack me!" protection inside the evaluation version of perl2exe, but it seems odd.
 
3. Not tried it with perlapp, I hope it works with this.
 
4. When adding resources with ResHacker, give the resource the same name as you passed for the filename of new Win32::GUI::Bitmap/Icon/Cursor. For instance, if you're doing new Win32::GUI::Bitmap("two.bmp") then your resource should have the name "TWO.BMP".
 
I had to test this by ResHackering my perl executable. Hopefully someone out there has shelled out for perl2exe full version or perlapp, and if that's the case then please test this on those two tools to see if it works.
 
Feedback please.
 
Steve

I agree with your analysis - I especially like the idea of bitmaps, Icons and cursors to check for resources first, and then to look at the file system (would solve the problem of running in "dev" mode with the perl command line, or running the exe direct).
 
How easy would it to be load other binary objects in from the exe? For example, having other image formats or storable created objects.
 
As for adding resources - I can see the benefits of having a native solution, but it would create massive scope to mess around with the perl exe:) Perhaps the first step is to point to ResHacker, with a step by step guide on how to use it?

I'd find this functionality kinda handy. Loading resources from the exe is very simple, and it would not be too difficult to extend the Win32::GUI::Bitmap, Icon, etc. objects to accept an additional argument that indicates that the resource should be loaded from the exe rather than from a real file on disk (in fact, it would actually be a trivial matter to do this).
 
What is less trivial is getting the resources in there in the first place. While ResHacker lets you do it, it'd be nice to see a Win32::GUI native way of doing it. Microsoft provides functions for adding, deleting and replacing resources in executable files and I propose we either:
 
1. Add this update/add/delete functionality into Win32::GUI so that applications can fiddle with their own resources. This may be an exceptionally bad idea (what exe file will it think it's using when running straight from Perl? We dont want it messing with perl.exe's resources)
 
2. Create a small tool that is distributed with Win32::GUI to pack resources into the exe. I doubt we can re-dist ResHacker with win32::gui and it'd be nice if there was this functionality provided. The Win32::GUI::Bitmap, Icon and Cursor objects could then be modified to first check for a resource identified by the given filename in the current running exe, and if it's not found attempt to use the given filename to load an external file. This seems the best mode of operation to me.

Hi,
 
One the problems I have when I ship my exe is ensuring that all the resources (bitmaps, cursors and config files) are valid when my app starts up. Typically, just including them in a sub directory can cause problems since the user could delete or alter them. The ideal solution would be to package the resources into the exe and extract them at runtime. See:
 
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winui/WinUI/WindowsUserInterface/Resources.asp
 
Adding the resources to the exe is quite straightforward (with reshacker) but I'm not sure how easy it would be to implement these function calls (or even it is possible), would anyone find this kind of functionality useful?
 
Cheers,
