I'm able to create and use dll in C++ using VS 2008 express edition successfully.But problem is
I don't want to copy the DLL to the executabe's folder. My lib setup is perfect. If coping the dll to executable's dir then it's working fine.But I want to setup path for dll/ something like this in the project settings to avoid copying the dll somemany times.(Just by providingg the dll path it should work)
Or else you r having any other idea is also appriciated.
FYI: Don't want to use LoadLibrary().

The studio allows you to put executable in one folder and the dlls in another folder - it will work for the debug session - you need to set the output dll folder as the working directory for the executable.
Your executable will find its dlls if they are in the same folder or the dlls are somewhere in the PATH folders (system settings).
>> I wat my dlls will be in separate DLLs dir
For your exe to locate the DLL it has to comply with one of the following search path requirements...

Search Path Used by Windows to Locate a DLL
With both implicit and explicit linking, Windows first searches for "known DLLs", such as Kernel32.dll and User32.dll. Windows then searches for the DLLs in the following sequence:
- The directory where the executable module for the current process is located.
- The current directory.
- The Windows system directory. The GetSystemDirectory function retrieves the path of this directory.
- The Windows directory. The GetWindowsDirectory function retrieves the path of this directory.
- The directories listed in the PATH environment variable.

In the Debugging section of the project properties, there is a section called Environment, which you can use to configure the runtime environment for the application being debugged. You should be able to add the path to your DLL there using something like PATH=%PATH;<DLL Path> (although I have never tried this myself)

Create a Standard DLL with VC++

The .DEF file explicitly identifies the exported functions, even if the compiler can do it in a "hidden" sort of way for you automatically. All DLL programs must habe a DllMain, even if some underlying foundation class (or whatever) will provide one for you in a "hidden" sort of way. The reasons for doing something in an open, obvious way are the same as the reasons for understanding that there are not little people magically living inside of the television set.

You can set the same folder for the "Output Directory" for the executable and the DLL projects - page General. On Debugging page you can set also the "Working Directory".
If you have the executable and the DLL in one solution, you can set "Project Dependencies": executable depends on the DLL.
In the project settings of the executable, in the linker section, on the Input page you can set "Additional Dependencies" - for example, if your DLL has name MyLib.DLL, in this dependencies field you need to set MyLib.lib</A>. In the same Linker secyion on General page "Additional Dependencies Directory" allows to set a folder where all lib-files are located. In this case, it should be the output directory.
