Setting Picture of cammand button

I have a command button that is set to 'Style=Graphical' and it has the 'Picture' property set to an image on the hard drive. This is Ok, but how do i set the picture manually in the code to something else? Im doing this at the moment bit the compiler doesnt like it.

VB Code:

CommandExit.Picture = "C:\a.bmp"

Do i have to use 'Set' instead or something? Thanx in advance

Use LoadPicture function instead of directly saying the path

Command1.Picture = LoadPicture(FileName, etc, etc ....)

Thanks Techy! Knew it was something like that but wasnt sure of the exact syntax seeing as i havent done it b4. Full marks!
