RichEdit Control

I am trying to create a log so that i can monitor statistics in the program im running.

Ive successfully set up the Richedit control and everything, i was wondering if someone could explain to me how I could actually add data to it, also if someone could explain how i could format the data (change color, size, bold, italics) and how i could save all the data to a .txt file.

I have the file stream code set up:

Code:

---

case LOG_BUTTON_SAVE:
{                                       
    SaveFile(hWnd); //Just an Open Save Dialog Function - Ignore
                                               
    char *Buffer = new char[1000];
                               
    //**saving code goes here**
                                       
    ofstream fout;
                               
    fout.open(FileName, ios::ate);

    fout << Buffer;
                                       
    fout.close();

    if (Buffer)                                   
          delete[] Buffer;                       
break;
}

---

I was wondering which message I would have to send to the Richedit control in order to get its contents into the Buffer i declared in the code above.

Thanks

Here is the reference for the Rich Edit control.
Start with EM_SETTEXTEX Message.

Thanx for the reply Codeplug,

Ive never used MSDN before and I just now realized how valuable it is!

Thanx again

Theres still 1 problem though:

When i try to compile the program MSVC++ says that EM_SETTEXTEX is not defined, ive included the richedit.h header but it wont work

Hmmm, I don't have it either.
Use WM_SETTEXT instead.

i found out you need richedit 3.0 or 4.1 which supposedly comes with windows xp, somehow I dont have it, so im looking around MSDN until I find a download link, ill post the site once I do, in the meantime ill try windows update maybe i missed something

So far ive search all of MSDN and Microsoft.com and found NOTHING, so i tried google instead, apparently the only way to get it is to steal it from the office 2000 resource kit:

Im still looking around, i cant beleive its this hard to download 1 dll which microsoft is supposed to make available on MSDN.

Also WM_SETTEXT cant append strings to the end of the edit control, instead it just sets that text alone, I need a function which will append the text to the end on the rich edit control

You can also use mose the Edit control messages for Richedit controls as well.
Use EM_REPLACESEL to insert text at the caret position.

EM_SETSEL will set the caret posistion.

I've only ever used WM_SETTEXT and EM_REPLACESEL to add text.

I might be mistaken, but I think you can only use EM_SETSEL if you want to place the cursor at a position < 64K on Windows 95/98 machines.
If you want to scroll through a larger piece of text then you should use EM_EXSETSEL.
