How cand I include a bitmap in my custom component (if is possible)?

Question

I am writing a component (a button) which needs a bitmap to be displayed on it. I don't want to make an ImageList property and the user assigns an image. I want that button to have only the image chosen by me.

I tried to include the bitmap in a resource file but when I try to access it I get "Resource not found" error message. This is what I've done:

myres.rc

FIXED BMP "fixed.bmp"

I compiled the resource file with: brcc32 myres.rc

Then I included it in my component unit...

implementation
{$R .\resources\myres.res}

And access it with...

MyComponent.Glyph.LoadFromResourceName(HInstance,'FIXED');
// MyComponent = class(TSpeedButton)

Edit1: I deleted the {$R .\resources\myres.res} directive and I loaded the resource from menu Project -> Resources and it's working, both with HInstance or FindClassHInstance(MyComponent).

Using a resource editor I found that when I load the resource from the menu the resource appears with the name "FIXED" as it should, but when I load the resource compiled with brcc32 it appears with the name "0". It seems that brcc32 doesn't set the name correctly.

But I don't want to load it from menu, I want it to be loaded automatically with the component.

Edit2: Remy Lebeau is correct. I was using a wrong BMP format (the file starts with 'BM6' characters instead 'BM8' like Photoshop produce it, and it works).

Change BMP to BITMAP in your RC file, and change HInstance to FindClassHInstance() in your code:

FIXED BITMAP "fixed.bmp"

Glyph.LoadFromResourceName(FindClassHInstance(MyComponent), 'FIXED');
