How can I use <DlgRichEdit>Control ?

[vega]

I want to display the content of a specified file in this <DlgRichEdit> control.
Please, show me a example code.

Hi Vega, not sure what you mean by <DlgRichEdit> but I assume that you want to use a RichEdit control on a dialog. In your RES file...

#define IDC_RICHEDIT 1001

CONTROL "RICHED",IDC_RICHEDIT,"RichEdit20A",WS_CHILD+WS_VISIBLE+WS_TABSTOP,30,127,186,152,WS_EX_CLIENTEDGE

Load the appropriate rich edit DLL using LoadLibrary then process the messages for it in your DlgProc, search for RichEdit in the forum, there are over 100 examples and questions.

 vega,

I'm guessing that you are having problems trying to use the DlgRichEdit macro either because you have not loaded the required DLL, or have loaded the DLL for the wrong rich edit version. This is a bare-bones example that can use rich edit version 1 or version 2/3.

And donkey, before you protest the example is assembly code because it directly specifies not just one, but two actual instructions :lol
