Get Data of win back with GetBitmapBits and create bitmap from it with SetBitmapBits .
then save bitmap to file .
Then read the bitmap with CBitmap::LoadBitmap and display it in win .

Hi,
I am using this kinds of TextOut in my application to display some text.
pDC.TextOut(110,145,"ON ");
pDC.TextOut(175,282,(CString)sTime ).......
..........
But if i chnaged my system resolution,totally the texts are displayed very closely with out any space and text are goes to top.My resolution is 800/600 pixels,I coded my application with this resolution.When i changed resolution to 1024/786 pixels then it dislays closely that is its get compressed.

your problem is when you change resolution from 800 to 1024,yes or no?

Ask a problem,about template:)

I feel rather than hardcoding the values make it relative to the value you get from :-

int GetSystemMetrics(<br />
  int nIndex<br />
);

int GetDeviceCaps(<br />
  HDC hdc,     // handle to DC<br />
  int nIndex   // index of capability<br />
);

<<<<<<<<<class.h>>>>>>>>
#pragma once
template <class t=""> class Tem
{
public:
T rxg(T a);
};

<<<<<<<<<class.cpp>>>>>>>>
#include "stdafx.h"
#include "class.h"

When you make a class template you need to globaly define the object type you are using in the class.h there are other ways to solve this also :-
Look for class template instantiation.

In some case, I would like my application to hide its dialog as soon as my application start. I post message "WM_HIDEWINDOW" to the main dialog self in OnInitDialog, but there is a flash in screen before the dialog was realy hidden. Is there any other good idea to prevent or reduce the flash?

Nothing impossible, Nothing sure
