Simple: Under the green bar at the top of the codeproject page is a input filed labeled "Search".
Just enter "jpeg" in that field and press "Return".
Et voila!
You get any number of articles about reading, decoding and displaying jpeg pictures. Try out a few solutions and produce your personal blend.

Failure is not an option - it's built right in.

Is better you see a short code

#include atlImage.h
CImage m_Image;
m_Image.Load(filename);
m_Image.BitBlt(dc.m_hDC,CRect(0,0,640,480),CPoint(0,0));
//in the end use of 
m_Image.Detach();

Part of button image becomes invisible after click

There is a button with image. When I click the button, the dotted lines denoting the focus of a button is coming and
part image becomes invisible and if I click somewhere else in the dialog then also part of image is not becoming visible.
The code is as follows:

CButton *cb = ((CButton*)GetDlgItem(IDC_BUTTON2));<br />
bmpForBtn = CreateMappedBitmap(AfxGetInstanceHandle(),IDB_BITMAP1,0,&clrMap,1); <br />
cb->SetBitmap(bmpForBtn); <br />

Any ideas would be greatly appreciable.

That code looks ok . You have not given the details of clrMap. At which point you are calling this ?? (and hope you may checked the property bitmap of the button in resource editor to true, if not do it. )

If u can Dream... U can do it

Is there any reson for using this API ? Its documentation says, Creates a bitmap for use in a toolbar.

I've been using VC++ 6 and office 2003 for a long time without any problem.
But when I install office 2007, my VC++ 6.0 cannot open file or add file to existing project, but it's still able to open workspace, create new project, compile, run, ... do everything else perfectly !!! But any time I choose File/Open or Project/Add to project/Files then visual C shutdown immediately without saying anything !!! It just closes like it was killed !
Uninstall office 2007 and things go back to normal.

Have any one suffered the same situation ??

Try to include Winbase.h in your source file.

Did you see MSDN
To compile an application that uses this function, define the _WIN32_WINNT macro as 0x0400 or later

Define _WIN32_WINNT accordingly, make sure, you have latest platform SDK installed.

You are using very old header files. You need to download the latest SDK.
