Message Box

Anonymous

In part of my program, I made it give a "yes, no, cancel" MessageBox to the user, and it does that. But the text in it make it span all the way from one end of the screen to the other, making it look ugly. How do I tell it to go to the next line after the first line exceeds a certain length?

Just insert line breaks ("\n"), in your display string. If the length of your string varies, then you might want to write a simple funtion that breaks up your input string for you before passing it on to the messagebox

Yeah, my text varies. Guess I will have to write a splitting function then, was wondering if there was already one included in MFC. Thanks.

//! @param  strString   The string to be wrapped.
//! @param  nWrap       Wrap margin.
//! @param  lines       Collection of wrapped lines.

You could create a dialog in the ressource dialog editor, with 2 buttons and 1 Editbox. Press Strg+W and the Classwizzard will come up, here you can add variables linked to the Editfield or functions that operate when buttons are pressed and more. If you set up all fine you can include the dialogclass in your app, write the sentense you want to the variable in your dialogclass,say mydialog.DoModal();, react on buttons, and have a good time. No more than 10 minutes on it all.

It can be generically applied to any kind of message box.
Less internationalization required.
Takes less than 10 minutes to implement. :)

Might want to add some handling for strings that do not use correct spacing (i.e. do not have a single space after a comma, colon, etc.). Wrapping can also be done right after a hyphen. Peace! -=- James

If you think it costs a lot to do it right, just wait until you find out how much it costs to do it wrong!

Good point. I'll genericize it and will post an article soon. Thanks! /ravi My new year's resolution: 2048 x 1536 Home | Articles | Freeware | Music ravib@ravib.com
