 Black triangle on command button?

Hi Roland,
 I have a command button that opens a pop-up menu when the user clicks
 on it. The Windows-styleguides say that there should be a black triangle
 at the end of the caption of the command button. This will show the user
 that a pop-up menu will open if the user clicks on the button.

 So this is my big question: How can I add such a black triangle to the
 caption of the command button in VB4/32 without using additional OCXes?


 Although I've not tried, I think you could do the following. If your Caption
 does not change quite often, you can create a .bmp with a triangle at the
 end of the caption and then displa that .bmp on the CommandButton.

 Hope this helps,

        However, if you use an Icon for the Triangle, no matter what color they
make their Color Scheme,
you can use transparent colors to extract the Icon over whatever colors you
want and all you need to worry about is that your Icon is in the right

        I would suggest using and extractIcon from an ImageList or just use
DrawIcon API to do the job on the
Paint procedure of your form.... (if the button never gets disabled...)
