Radio Button crashes program when clicked!?!!

[mao_03]

Hi all,

I want to replace normal buttons by radio buttons. So far it works fine. But when i click the damned radio button the program hangs no error no nothing, it just hangs.
The methods called on click do nothing by now!

What i want to do is select one of tree options with those radio buttons and therefor i have first to lock them against each other (only one can be selected) and then change a variable. any ideas on how to do that??

Does MFC have a class for radio buttons such as CButton for normal buttons??

10x for the help

I'm not sure why your program would be crashing, but here is a link to a page that shows you how to add radio buttons to a dialog box:

http://msdn.microsoft.com/library/de...Dialog_Box.asp

If this doesn't bring you to the right page then enter Radio Buttons into the search box and click on the link for Grouping Radio Buttons on a Dialog Box.

I hope this helps.

I can't tell why your program hangs, 'cause you provide too few details.

Does MFC have a class for radio buttons such as CButton for normal buttons??

Yes! It's called.......CButton . Serious, now: Use the GetCheck() / SetCheck() member functions to see whether the radio is selected ot not.

Ok, i get a notification when the button is clicked:

afx-messagemap:

on_button_clicked(idc_radio_button_clicked, onradiobuttonclicked)
...

then when implementing the onradiobuttonclicked the function is empty (until the stops hanging !)

if i got you right, i could in this onradiobuttonclicked() function use the getcheck to see if it is checked or not. But since with the empty function the program hangs i expect it to hang too when i use getchecked.

Tricky?
