Does anyone know how can I do that...

char szCurrentDir[MAX_PATH];
::GetCurrentDirectory(MAX_PATH,szCurrentDir);//returns current directory

But I need to POST some variables at the same time along with their values

CString str;
long count = addIns.GetCount(); //powerpoint addins
for(int i=0;i<count;i++)>
{
    //Here I have to use Item(..) as mentioned above.
    VARIANT var;
    var.vt = VT_I4;
    var.lVal = i;
    LPDISPATCH lpDisp = TheInterface->Item( &var );

How do I convert integer or long to VARIANT* type in C++?

CComVariant varTemp (lMyLongVariable);
HRESULT hr = SomeFunction (&varTemp, other, parameters, here);

CString MakeHexText (BYTE *byIn, UINT nCount)
{
   CString strReturn, strByte;
   for (UINT n = 0; n < nCount; n++)
   {
       strByte.Format (_T("%02x"), byIn [n]);
       strReturn += strByte;
   }
   return strReturn;
