Control Icon?

[Vibas]

Hi,

I am playing around with make my own controls and everything is going ok: I has created my controls and registered it succesfully in Windows with Regsvr32. But now, there is a simple question: how can I set my own icon to be showed in the components window, instead that regular one (the four little boxes with a pencil)?

Thanks!

Set the ToolBoxBitmap property of the Usercontrol.

Thanks Bruce, it worked.

I have another doubt: why the icon I draw becomes smaller than the other icons on the component bar?

i can't still figure that out. we are to use 16X15 bitmap, but its always getting smaller than what is there in the box. i increased the bitmap size with no improvement. i guess you'll have to manage that!!

Hi,

I was researching a little and found out that the maximum size accepted is about 15 x 16 pixels. For any unknown reason, the VB native controls can break this barrier.
I had some problem about the icon quality too: the most os time they appeared distorted, and some other times, some colours didn't appears.

After a lot of experiences, I realized that:

1) The icons made in Photoshop or another pro image application don't behavior well, even if you save it as BMP file because they deal with at least a 256 colors pallete. Seems that VB likes icons saved in 16 colors mode. Then, I liked to use the Windows Paintbrush to do that

2) If you use a solid background colour, this color can disappear. I think that VB guess that this is the colour to be the transparent one (???). Anyway, I realized that the problem disappears if you build a margin with 1 pixel round the entire icon, but don't use the same colour of the margin inside the icon, or this color will transparent. For instances, if you draw a red border all over the icon (a square), when you draw something in red colour inside the icon it will be transparent instead red.

Maybe I am beeing confusing???
