How to create .dll and .lib files in a single build in VS2005. Is there any need to include some files for that ? Please help me.

What's your problem exactly ? Where are you stuck ?
You need to create a dll project (New Project -> 'Visual C++' -> 'Win32' -> 'Win32 PRoject'). Click next and you'll be able to select DLL as application type.
The library file will be generated automatically once you have at least one exported function.

Hi. Thanks for the reply.
My problem is i am creating a new project in VS2005 from the existing project of VC6.0. It is not able to create the .lib automatically with the dll. I have checked all the settings of the project but could not get success.
So i wanted to know whether any new thing has to be done in VS2005 while converting the old project to create dll ?

Do you have at least one exported function ( one that is starting with __declspec(dllexport) ) ?
Did you use the conversion wizard to convert from the VC6 project to the VS2005 project ?
|

Yes i have the following function with __declspec()
#define SS_NOTHROW __declspec(nothrow)
and yes. i have used the option File -> New -> Project from ExistingCode... option while creating

First that's not a function and second, this macro doesn't even export a function.
Just to make a test, add this piece of code to one of your header file:
int __declspec(dllexport) Test()
{
return 42;
}

You need to export at least one function so that the lib file will be generated. In your case, if no lib file is generated, it means that no function has been exported. So, it means that your dll is useless  (a dll that doesn't export anything is completely useless). If you need to add this function to have a lib file generated, then I think you have a problem.

Hi
I want to ask that is that possible to display a picture with jpeg format in visual c++?If it is possible how can I do that?
Thanks

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.

JPEG format is the compressed file format. Please refer details here[^].

Yes you can use of CImage class for show bmp,jpg,gif,png and also use of GDI+ after load use of WM_ERASEBKGND for show it
|
|

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));
m_Image.Detach();

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.
Best Regards,

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.
