vc Resource item display can't be access & is disable

I use VC and I'd like to load a bitmap file on my user Dialogue. But when I choose the picture item and add it into my Dialogue. I found that the picture item can't be access by its property. I can only show the bitmap by adding a bitmap item and I can开发者_JS百科 not use the picture item. why? Could have anyone else tell me how to enable the picture item in my Dialogue , so that I can edit the picture item 's property??

Lovely everybody, I found my soloution, And Now I can show different Bitmap in my Dialogue without use any source code. Here is the Website that I found the problem:
