How to convert CString into LPTSTR ?

CString csStr = "Hello";
LPTSTR lpStr = csStr.GetBuffer( 0 );
csStr.ReleaseBuffer();

Getting Local Application Path in XP & Vista

typedef HRESULT (WINAPI * SHGetKnownFolderPathFn)(REFKNOWNFOLDERID rfid, DWORD dwFlags, HANDLE hToken,PWSTR *ppszPath);

PWSTR pszPath[1];
SHGetKnownFolderPathFn shGetKnownFolrPth = NULL ;

HINSTANCE hins = LoadLibrary(”Shell32.dll”);

if(hins != NULL)
{

shGetKnownFolrPth = (SHGetKnownFolderPathFn)::GetProcAddress(hins,”SHGetKnownFolderPath”);

if( shGetKnownFolrPth != NULL)
{
shGetKnownFolrPth(FOLDERID_LocalAppDataLow,0,NULL,pszPath);
CString csData=pszPath[0]; // converting from wchar to ANSI.
}
}





int GetCurrentUserLocalLowAppPath(LPTSTR szProfileDir,int dirlen )
{

memset(szProfileDir,0,dirlen);

if(IsWinXP() == TRUE)
{
GetCurrentUserAppPath( szProfileDir, dirlen );
}
else if(IsVista() == TRUE)
{
PWSTR pszPath[1];
SHGetKnownFolderPath(NULL,FOLDERID_LocalAppDataLow,0,NULL,pszPath);
//copying the pszPath to szProfileDir array
}
return 1;

MFC code to get the Path of Appliction and DLL

//MFC code to get the Path of  Appliction
CString GetExePath ()
{
   TCHAR szPath[_MAX_PATH];
   szPath[0] = '\0';

   GetModuleFileName( NULL, szPath, sizeof(szPath) );

   CString csPath(szPath);

   int nPos = csPath.ReverseFind('\\');
   if ( nPos != -1)
   {
       csPath = csPath.Left(nPos+1);
   }
   else
   {
       csPath = "";
   }

   return csPath ;

}


//MFC code to get the Path of  DLL if it is loaded from different path
#include <atlbase.h>
CString GetDLLPath ()
{
   TCHAR szPath[_MAX_PATH];
   szPath[0] = '\0';

   GetModuleFileName((HINSTANCE)&__ImageBase, szPath, sizeof(szPath) );

   CString csPath(szPath);
