Question

I’m writing a small app that needs to be small and run on old systems. That’s why I can’t use .NET.

How can I change the color of the Edit control?

Here’s the .NET code:

textBoxLog.SelectionColor = color;
textBoxLog.AppendText(String.Format(s + "\n", parameters));

Update

Okay, so I managed to place the control on my form. How do I use the EM_SETCHARFORMAT message?

LoadLibrary(TEXT("Riched32.dll"));
CreateWindow("richedit", text, WS_VISIBLE | WS_CHILD | type, left, top, width, height, parent, NULL, NULL, NULL);

Update 2

I solved it. Turned out to be pretty easy:

SendMessage( textBoxLog , EM_SETCHARFORMAT, SCF_SELECTION, (LPARAM)&RedFont);

Where RedFont is

CHARFORMAT cf;
memset( &cf, 0, sizeof cf );
cf.cbSize = sizeof cf;
cf.dwMask = CFM_COLOR;
cf.crTextColor = RGB(255,0,0);
CHARFORMAT RedFont = cf;

Don’t forget to include “richedit.h”

Answer 1

The TextBox class doesn’t have a SelectionColor property. You are using a RichTextBox.

Use a rich edit control in native code, EM_SETCHARFORMAT message.
