The way that I do it is
AllocConsole();
m_hout = GetStdHandle(STD_OUTPUT_HANDLE);
SetConsoleMode(m_hout, ENABLE_PROCESSED_OUTPUT | ENABLE_WRAP_AT_EOL_OUTPUT);
If you say that it is not true that when the child process get deleted, the parent process also get deleted, then I don't understand why my GUI get closed when the user close the console window.

 I am developing VC++ Application using Managed Extensions in visual Studio .NET 2003. I have selected the .NET Console Application Template for this and included the necessary namespaces and dll files. Th problem I am being facing is: OnPaint Event Handler is not working (!unresolved link externals). How do I resolve this? I am pasting the code below.
#include "stdafx.h"
#using <mscorlib.dll>
using namespace System;
//-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
#using <system.dll>
#using <system.drawing.dll>
#using <system.windows.forms.dll>
using namespace System::Windows::Forms;
using namespace System::Drawing;

void OnPaint(PaintEventArgs *e);
private:
//To display graphic file on the we must use Bitmap Class object like:
Bitmap *m_Bitmap;
// Event handlers for the Menu Commands
void OnMnuOpen(Object* sender, EventArgs *e);

};
//Constructor

MainMenu *mnu = new MainMenu();

MenuItem *item = mnu->MenuItems->Add("File");
/*

*/
item->MenuItems->Add("Open",new EventHandler(this,&MyForm::OnMnuOpen));

but I was wondering, why did you select a console application for what it looks a Form based application ?

Does Outlook COM expose it as an interface?

hi David,
Outlook exposes its functionality through many interfaces. the application ID of outlook is outlook.application.u can search it in registry.then u can find out the dll for that. and after that everything is in ur hand.
bye,

I knew this. I was prodding zeeshan to do some research on his own. I'm a big fan of the old "Give a man a fish and you feed him for a day. Teach a man to fish and you feed him for a lifetime." adage.

I am currently doing an application and i am required to save data from edit boxes to a file and load them when need. I am familiar with the C++ , FILE *fp method of file i/o. But is there a proper and simple MFC method for doing file i/o ? (Sample code greatly appreciated =) )
Thanks

See the CFile and CStdioFile classes.

You can also consider persisting data using CArchive in MFC.

Perhaps BeakX could, too!

You can also use fstream.h
To get data from the file make an object of ifstream
and to write data to file, make an object of ofstream
then use these objects just like cout and cin in c++. These are very easy to use.
You can visit msdn.microsoft.com for the help on ifstream and ofstream.
Good Luck.

I belive CStdioFile is one most stable File handlling class MFC have

Hello,
I have the need for a tab control that renders slighly different from the default control provided in the mfc library. I would like for it to display tabs on the left hand side, but with horizontal text. Additionally, I would like to have navigation buttons (up/down), and for each tab to have a close button. Finally, one must be able to add 'pages' dynamically. In short, I would like to have something like :
No navigation needed
___________________________________
| TAB 1 [x] | |
------------| |
| TAB 2 [x] | |
------------| DIALOG 1 |
| TAB 3 [x] | |
------------| |
| |
| |
|______________________|
Navigation needed
___________________________________
| UP BUTTON | |
------------| |
| TAB 4 [x] | |
------------| DIALOG 5 |
| TAB 5 [x] | |
------------| |
| TAB 6 [x] | |
------------| |
|DOWN_BUTTON|______________________|
I dont mind doing the coding myself, but to be honest, I dont know where to start as far as having it render in this manner. Any suggestions or sample code would be greatly appreciated.
Thanks,
