EResNotFound exception thrown by custom component

mtronixmtronix
in C++ Builder
Hello,
OK, so here is some background. I am upgrading this old program from builder 4. Now, the old program contained custom built components which I can re-build. However, these guys have issues. The components were all made as *.bpl packages which you can later add using Component->add component in the IDE
One of the components has several bitmaps in it. The *.bpl file has a resource file, "rmsctrl.rc" which points to each graphic like this

IDB_LEVEL8 BITMAP "level8.bmp"

and I have picture level8.bmp extracted in my directory.

Now this file has a header that says #include "Resource.h" at the top of it.

Inside Resource.h I have

#define IDB_LEVEL8 1009

So now, the main program makes a call using

FBitmap->LoadFromResourceID((int)HInstance, S_BitmapIndex[FLevel]);

// Draw stuff on canvas
FBitmap->Canvas->StretchDraw(Rect, FBitmap);

// Draw RMS values
DrawElectrodes(FBitmap->Canvas, false);
DrawVectors(FBitmap->Canvas);

The package will build. When I place the package on a form, it even shows the bitmap. However, at runtime, it throws the error EResNotFound exception 'Resource 1009 not found'

Any ideas?

Thanks

    Hi,
    I needed to add a pragma statement to include the resource file in the original component project.

    Hello,
    I found the solution. I needed to add a #pragma "Resource.rc" statement at the top of the package. This let it work.
