Visual Studio 2008 - Creating DLL

hi,
I have insatlled Visual Studio 2008.How can i create DLL in Project type Visual C++.Since I have not much worked with VS2008, I would be grateful for help

Steps to Create Your DLL

• Create a Win32 Dynamic Link Library project, adding a *. cpp and a *. h file.
• In the *. cpp file, create a class instantiated from the CWinApp file.
• In the *. h file (here it is SourceFile.h), define the functions to be used. Also specify the dllexport value for the _declspec function.
• Then compile the DLL.
• Create a normal Win32 Application with a *. cpp file and a *. h file.
• In the *. h file, (here it is AppHeader.h), declare the function with the dllimport value of _declspec

In the *. cpp file, use the function.

Code:

---

# Include "AFXWIN.H"
  # Include "AppHeader.h"

  class MainFrame: public CFrameWnd
  (
      public:

          Mainframe ()
          (
              CreateProcess (0, "Trial");
          )

          OnLButtonDown void (UINT nFlags, CPoint point)
          (
              int res;
              char str [5];
              res = Calc (998, 226);
              sprintf (str, "% d", res);
              MessageBox (str);
          )

          DECLARE_MESSAGE_MAP ()
  );

In the Link tab of the "Project-> Settings" dialog, go to the text box labeled "Object / Library Modules" and specify the path of the DLL file. Then copy the compiled DLL file to your current appliation path directory and run the program.

If you want to create a "managed" (i.e. CLR-based) DLL to be used from C#, I think that you should choose "Class Library" (under Visual C++ / CLR node in the "Project types" tree). This class library will export "managed" (CLR-based) classes, i.e. it will have an object-oriented structure (with classes, methods, etc.)
You can create these classes using C++/CLI extensions to C++ language, and you can use these classes in other .NET languages, including C# and VB.NET.

I had a similar project on the page seen, but this looks promising. Thanks you.
