I'm using FindFirstFile to get a list of directories.

In the past I've used it as shown below with VS2005.  In this new project I'm getting a C2664 error because it wants the first parameter to be type LPCWSTR and that a const char*.

I can just cast it to a LPCWSTR but does anybody know why this error is showing up?  

Thanks.


      WIN32_FIND_DATA FindFile;
      HANDLE hFind = INVALID_HANDLE_VALUE;

        string myDir = "C:\\Temp\\*";

         hFind = FindFirstFile(myDir.c_str(), &FindFile);  

This results in the following:
error C2664: 'FindFirstFileW' : cannot convert parameter 1 from 'const char *' to 'LPCWSTR'
