RibbonX: Custom Image Callback Sample in VC++

[Devansh]

Hi there,
I am developing a COM outlook addin implementing IRibbonExtensibility
interface in VC++.

My question here is, how do I use "loadImage"/"getImage" tag? I could
not
find any sample code which I could use specially in VC++.

Do I need to include the callback corresponding to loadImage or
getImage also in IDL file with the other callback functions?
If no then how, what and where I am going to write it?
If yes then what I am going to write into it?

In one line my question is, How to attach a custom image to a button
created in Ribbon with VC++?

Kindly help me in this.

Thanks,
Devansh

PS: I am expecting a Sample Code in it.

I don't do C++ so I can't be specific as to that language, but getImage is a
callback the same as getVisible or getEnabled are. You need to supply a
callback function for getImage that provides an IPictureDisp object as the
return value of the callback. For C# the callback signature would look like
this, assuming your XML line had getImage="GetRibbonImage":

public stdole.IPictureDisp GetRibbonImage(Office.IRibbonControl control)
{
// get the image as IPictureDisp, as an example iPic

return iPic;
}

The loadImage callback has a C# signature like this:

public Bitmap LoadImage(string imageName)
{
Assembly assembly = Assembly.GetExecutingAssembly();
Stream stream = assembly.GetManifestResourceStream("your project name
here" & imageName)
return new Bitmap(stream);
}

That is from the example at

Maybe that will help you.
