Oh I'm sorry.
I'm getting error at readrtf () function.
I think I'm passing the wrong information to readrtf().. especially parameter one. Mapirtf.cpp explain about readrtf() defination as follow: but I dont' know where to get Profile name..

<br />

In the example of readrtf() provided by microsoft, http://support.microsoft.com/?kbid=172038[^] get the session, mapi message and the logon then readrtf(). I'd tried to get the session of as follow, but doesnt' work.. I dont' know how to covert that vb example code (from 172038) to c++.

<br />
<br />
	CoInitialize(NULL);<br />
_ApplicationPtr pApp;	<br />
		hr=pApp.CreateInstance(__uuidof(Application));<br />
		if (FAILED(hr))<br />
		{<br />
			MessageBox("Unable to instantiate Outlook.","Outlook Error",MB_OK);<br />
			return;<br />
		}<br />
		<br />
		pNS = pApp->GetNamespace(_bstr_t("MAPI"));<br />
		_NameSpacePtr session = pApp->GetNamespace(_bstr_t("MAPI.Session"));<br />
<br />
<br />

thanks for your reply David.

I also have another question
I tried to include mapix.h and mapiutil.h to my project so I can call
MAPIInitialize() and LPMAPISESSION session memeber functions.
However, when I run the application.. I got error saying
WCHAR: is redefiniation; different basic types. error is in "MAPIDef.h"
what am I missing again? do I need to support the unicode? if so how can I do that?
I tried to add

#ifundef UNICODE
#define _UNICODE

to stdafx.h but I still get the same error.
What can I do to get the rtf message body of email?

Thanks

Where to place code to be ran immediately after all mfc contruction is completed.

I'm messing with the status bar of my MFC SDI app to change the message from 'ready' to 'working' while doing a lengthy computation using the setup linked below. I've got everything working except that intially there is no value for the default status text. I've tried calling StatusBarMessage() from the constructor and OnCreate events, but in both cases it causes a null reference exception because the GUI components haven't been created yet. Where should I move the initialization call to.

Which pane of the status bar are you attempting to change?

The left most that normally displays "Ready" or a description of the current menu/toolbar item.

I solved my problem by calling the init code in InitializeInstance. *duh*

I also 'handled' WM_SETMESSAGESTRING in one of my MFC apps, and in that case I could set the message to anything I wanted, and also avoid messages I did not want to appear in the status bar that the framework might have posted automatically.
Oh, I also remember I did this because the message text was not in pane 0 of my staus bar, it was in the right-most pane instead of the left-most pane.

Newlines in my Edit Box

I'm trying to make an edit box that will involve more complicated entry than just one line. In fact, sometimes I want to prefill my edit box from a file. I've already set the multiline property, and the 'want return' property, so it appears to be working properly when typing into it, but if I load in information from a file, the newline characters get changed into a funny vertical blackened box. How can I get the edit box to format them properly, turning the newline character into an actual newline?

Use \r\n instead.

\r = carriage return

edit controls apparently refuse to honor new lines (\n) and require CR/LF pairs.

I've added several items to my menus at designtime; thier Enabled properties are true, and their grayed properties are false; but at runtime they're grayed out and inactive. Is there something I need to do to activate them?

Problem fixed. I had my handlers set for ON_UPDATE_COMMAND_UI instead of ON_COMMAND. Been too long since I've done anything with mfc obviously.

Hi.

How could I know when Windows is closing.
Because I have a program always loading and I want to trap the Window's closing, to show a message box.

You may override the WM_NCDESTROY message handler like this

void CyourDlg::OnNcDestroy()
{
	MessageBox("Dialog is going to be closed...");

	CDialog::OnNcDestroy();
	
}
