Restricting the amount of chars in a textbox.

[JpEgy]

I'm making a simple calculator in VC++.net (i don't compile .NET code though). What would be the best way to do this?

Best way to make a calculator or best way to restrict the EditBox?

[JpEgy]

The editbox yes. I made the dialog and the textbox in the Visual C++ IDE, so it's not plain API.

Anyone?

Hmmm, I thought someone would have answered this by now. The answer's actually pretty simple:

 SendMessage(GetDlgItem(hWnd, IDC_TEXT), EM_SETLIMITTEXT, (WPARAM) size, 0); 

Simply replace hWnd, IDC_TEXT, and size with the parameters that you want.

Because it's no function, it's a message. You better search the edit box reference of MSN.
