I have an Edit control for hex input, and I'd like draw it with spaces between every two characters (the user doesn't actually type any spaces):
43 4F 44 45 50 52 4F 4A ... etc
I'd rather not use SetWindowText to shove the spaces directly into the text, since I'd have to have special handling for editing, cutting, pasting, undo, validate and all.
Is it possible to do the formatting at display time instead? I looked through the MFC source and I didn't see any CEdit draw methods that I could override.

Look in the CEdit section here, there are several masked edit classes if memory serves.
|
|
|

The masked edit classes keep the literals within the data, and so they have to have special processing for all edit and cursor functions. I could adapt one of these useful classes to insert that space every two characters, but it seems like overkill. 
I'd like to keep the text data the way the user enters it, and mess only with how it would get displayed. My idea is to grab the draw method for CEdit and override it with a function that formats a copy of the text right there, and displays it. I like minimal added logic.
Problem is, I don't have any idea where the CEdit control is drawing itself. I looked in the MFC sources and I can't find anything like CEdit::OnPaint(). Can anyone offer any clues on this?

Mabe you can handle EN_UPDATE and reset the text in the control to have every third letter a blank?
|

That's an idea I can try. Not as clean as I hoped, but if it does the job, I'll use it.

Hello fellas
Which GDI+ class lets you open a bmp file and draw it on your CView derived class? And will it take care of painting or do we have to keep re-rendering it in the OnDraw?
Regards,
Nish
p.s. I went through the GDI/GDI+ sections on CP. Haven't been able to find what I wanted

Ha! Straight from MSDN:
Image image(L"Grapes.jpg");
graphics.DrawImage(&image, 60, 10);
Go and do likewise...

Ok, more browsing through MSDN - try skipping the whole "new" thing, & using Bitmap::FromFile() to produce the Bitmap*.

I suppose... If you really *want* to. But memory leaks help keep your computer healthy by ensuring the swap file gets plenty of exercise, right?

Yeah, but I have VS.NET which takes care of leaking more than enough memory to keep the swap file in good health

Head over to http://www.codeproject.com/printing/[^] and read it. That'll give you a start, at least. The really hard bit will be HTML - i wish you luck with that, it could end up being quite a bit of work.

Does anyone know how to make a combobox sort data dynamically? Is there a CBS_SORT and if there is, how do I call it (note that I'm not creating the combobox dynamically)?
Thanks,
~ Selevercin
