Hello,

While I am able to load PNGs from a file into a toolbar using the "LoadBitmap" method, I would like to achieve the same result by loading the PNGs at runtime from a resource DLL.

LoadBitmapFromResource did not help me at all...

Is there any way of doing this ?

Thanks.

Hi,

How did you use LoadBitmapFromResource ?

Hi Oleg,

I have loaded my PNGs into a .res file as "custom" resources.

The .RC file may look like this:

[...]

IDB_TOOLBAR1 PNG toolbar1.png

IDB_TOOLBAR2 PNG toolbar2.png

I have tried to do something like:

IDB_TOOLBAR1 BITMAP toolbar1.png

IDB_TOOLBAR2 BITMAP toolbar2.png

but RC complains about the PNG not being valid bitmaps.

The .RES file is included into my project.

Then I try to load icons into the command bar by using the following call:

CommandBars.Icons.LoadBitmapFromResource App.hInstance, IDB_TOOLBAR1, Array(.....), xtpImageNormal

(on the final project, App.hInstance should be replaced by a resource only DLL handle)

The toolbar gets populated by buttons with text, but "garbage" instead of icons...

Where do I fail ?

Hi,

Just tried and it works. You need compile application and run exe to see bitmaps. From IDE resources are not loaded.

For png use

IDB_TOOLBAR1 PNG toolbar1.png

Thanks Oleg!

You are right! It works perfectly when compiled.
