I'm Trying to Create a Method that creates a file in an ATL ASP COM using C++.

Here is my code, but no file is created:

STDMETHODIMP CDV::Create_File(BSTR FileName)
{

     ts_out_handle = CreateFile((LPCTSTR)FileName,
          GENERIC_WRITE,
     0,
        NULL,
     CREATE_ALWAYS,
     FILE_ATTRIBUTE_NORMAL,
     NULL);

     if (ts_out_handle == INVALID_HANDLE_VALUE)
     {
          return S_FALSE;
     }

     return S_OK;
}


Thanks

Try to add this code:

...::CreateFile(BSTR FileName) {

USES_CONVERSION;
char *p;
p = OLE2T(FileName);

... CreateFile(p, ...)

If UNICODE in general is OK for you, just use



    ts_out_handle = CreateFileW((LPCTSTR)FileName

Note the capital 'W', it refers to the UNICODE version of 'CreateFile()'
