Implement the tracker using double variables instead of int/long.
Only do integer conversions when necessary - like when converting to pixels.

Yes, I'm fairly sure that at least someone has.

Hi chaps,
I have a CDialogBar that is most often used as a modeless floating (ie undocked) tool window.
My problem is that I want to intercept when the user clicks the little X in the top right of the title bar to close the dialog. To my surprise, Windows does not send my control WM_CLOSE or WM_SHOWWINDOW. In fact, it does not seem to send any Windows message that I can think of.
Does anybody know what (if any!) message it sends, or how to intercept this action?
Thanks,
Jim

Do you get a WM_SYSCOMMAND message?

I thought of that too - it's kind of on the system menu, perhaps it gets WM_SYSCOMMAND?
Nope.
I also tried WM_DESTROY out of desperation, it didn't get that either. I've drawn a total blank. Surely there must be SOME way to intercept this action?
|

Maybe this is a clue...
"Dialog bars are extensions to a main window and any dialog-bar control-notification messages,
such as BN_CLICKED or EN_CHANGE, will be sent to the parent of the dialog bar, the main
window."
I know it's in the MFC source somewhere....I can't seem to track it down. Maybe after the
caffeine kicks in.

Ah, now there's a new path to try - I'll give that a go next time I look at that dialog again.
Thanks,

SYSCOMMAND .. SC_CLOSE or have a look at this :- http://www.visualcpp.org/?p=39[^]

you can use CStdioFile for storing data in the file!

What is the better way to validate edit control?
Is it on KillFocus of the control or onOk of the dialog??
Is there any other better way?
Suggestions are appreciated.
|
|
|
|
|
Depends if your application must responds to an immediate change to the edit box value; i.e. if something must be refresh with the new value.
|
|
|
|
|
Is it possible to pop up message if the edit box value exceeds the limits on typing the value itself?
|
|
|
|
|
Yes, but why would you want to do this? Just send the control a EM_LIMITTEXT message and be done with it.

That depends on what you mean by validate. I find the best approach to be disabling the OK button until all controls have valid data in them.
If your edit control is for a phone number, there are many ways for the user to input such a number, and you certainly do not want to start complaining to them until you know for sure they are through entering data and it is indeed incorrect.

Thank you david for the suggestion. Yes its good idea to disable Ok button until valid data is entered. I will implement the same way in my project.
The requirement for me is like there are lot of dialogs which contains many edit controls, and i have stored all the minimum,maximum values for edit box in a file, so is it possible to write some generic version for validation check of edit controls, validation here is like if the input entered is greater or less than the maximum,minimum value it has to display a message.

Are you using MFC?
