Hello!
And may be you know also how can I check the button state, is it preessed or unpressed? There is no GetCheck method by CMFCTollBarButton class. So what is the way then?
Thanks a lot in advance.

As far as I know there isn't a way to do it like that, but that's because updating buttons on toolbars is different to buttons on dialog boxes.
To be honest, I'm not really sure I understand what you're trying to do - because you handle the OnUpdate function for that button (which is the only way to set it as checked), you must know the whether the button is checked or not already?

Oh no no, the first question is not mine. So I do not set it checked OnUpdate, I just want to know the state of the button.
But probably the solution is to handle global bool variable in ButtonClick handler.
I also found some method
CMFCToolBarButton::SetRadio <br />
Called by the framework when a button changes its checked state.
BUT
Remarks <br />
The default implementation of this method does nothing. Override this method to perform a custom action when the button changes its checked state.<br />

Please read the guidelines[^] before making another post.
Please use the "code block" option in the formatting pane to post code.
Please post only relevant code, explain your query clearly and pin point what is that you need help with.

Please format your code properly using the "code block" tag, it's almost unreadable. Did you define your static variable in a cpp file ?
|
|
|
|
|
and because two answers are not enough in your case, i'm repeating it to you (to be sure you got it well) :
you are supposed to post formatted relevant code only (not a huge copy/paste of an entiere file) !!!

Very well said. Why do some people think that someone on the internet will have the time to wade through the entire lot of code they post?

Hi All,
Can anybody tell me How to Embed a function in C Structure?
Regards
Sairam
|
|
|
|
|
a C structure is a class in C++.
if you're coding C++, then do it like you do in a regular class.
If you're coding C, no way.
|
|
|
|
|
You may embed a function pointer in a C struct.
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

It never hurts to take a look at the documentation[^] you know.

I'm a beginner in VC++. I would prefer to know how can get a colored text for my check boxes.
