[VB6] XP/Vista/Win7 Manifest Creator

[LaVolpe]

Jonney, what is in the resfile is not a manifest, not really. A manifest file will have a RT_MANIFEST resource type. That text in the res file is a CUSTOM resource type. It might as well be an email or ini file. Even though it is a manifest, it will never effect a compiled application. One cannot just throw a manifest in a CUSTOM resource and have Windows recognize it as a true manifest. To read CUSTOM resource file entries or any resource entries, really, one simply needs to process all the resource types. The project I wrote only messes with RT_MANIFEST resource types.

Try creating a test project, one command button, adding that resfile & appropriate Startup code to the project and compiling it. The compiled project will not be themed if themes are active. Now add a manifest via this project, recompile, & it will be themed; your updated resfile will have 2 manifests in it: 1 that is a true manifest and one that is simply a custom, text resource.

The bottom line is that the code is fine. If the ReadFile API fails, it should set resDataL to zero, else it will set it to how many bytes were read. Anything <> 4, in this case, is considered failure.
