Add resource file by code with Delphi

Question

I have a custom res file "myres.res". In this moment I use it on my application, I have add {$R myres.res} under {$R *.res} line inside my DPR project file and it work very well.

Now I'd like creare a VCL component with a boolean property "UseCustomRes". If I set UseCustomRes=True I'd like add the res file when I compile my project but if I set UseCustomRes=False I don't want use res file when I compile my project.

Is this possible? I don't know if it possible and how it is possible.

Answer 1

Resources are included by the linker based on the existence of special $RESOURCE directives. These directives cannot be switched based on the value of an object instance's property.

So, with the built in tooling there is now way to achieve what you desire. What you will need to do is to add a post-build step that modifies the output file by adding the resource if needed. A good example of a tool which does exactly this is madExcept.
