Location on a bitmap

[Bob Houle]

Using PB/DLL...

I have a large bitmap that takes up the whole
window and displays a map of the USA.

How can I have my program respond when the user
left-clicks on a particular state...say 'Arizona'?

Would I have to create 'hidden' bitmaps, or buttons?

You can take coordinates from WM_LBUTTONDOWN message.

But I guess that you have a scanned map.
If so, to recognize a state, you need to have a table (x, y, state).
Because I am doubt that you can prepare similar table, alone, what I can suggest - to color each state (incl. title) by unique RGB and to analyze a color by GetPixel.

Note, that with this approach some states can have the same color for eyes -
for example, RGB(0, 0, 128) and RGB(0, 0, 129)
