I have a bunch of radio buttons and when I click on them the button gets marked and all that. However, if I use the keyboard, they are hilited even more. A dotted rectangle encompasses the text. If I then use the mouse to click other buttons, the dotted rectangle follows.

How do I get that dotted (or dashed) rectangle to appear around the desired radio button without user intervention? I have tried "SetFocus()" and that doesn't work. Neither does sending a BM_CLICK message. Would I have to send a WM_KEYDOWN, WM_KEYUP arrow-key message sequence to the desired button? Probably the previous button (yuulk)?

What I want to do is guide the user to the proper control after an error. In this case the user composes a radio call that has many components. One of the features of the call is not done and I want to direct the user to the correct control for the fix. Wish I could make it light up!

Thanks,

Brian

You can use Spy++ to see what messages are sent to the control.

If you want to get the user's attention, you could use FlashWindow().

Sam,

All I wanted to do was to bring attention to a control. It has no title bar so the FlashWindow options didn't do anything. However, it would be perfect if it did, because that's just what I want. I bring the keyboard focus to the control but it is not obvious in a almost full screen dialog box with more than 70 controls!

If FlashWindow does not work when there is no title bar then I apologize for wasting your time. However note that a "flash" requires at least two calls. The documentation is not easy to understand; I have had to play with the function a bit to figure it out. To get a flash, we must use a timer to return a window to its original state. If you do two FlashWindow calls without a delay between them then you are not likely to see anything.

Hi,

If you implement the ownerdraw mechanism for your radiobutton control, you can change e.g. the text to bold, or change the color of the text.
