Here is my code in VC++, but it still doesn't work!

CString Oid,strOid;
char Result[255];
DartSnmp::ISnmpVariablesPtr Variables = pManager->Message->Variables;
  DartSnmp::ISnmpVariablesPtr MibVars = pManager->Mib->Variables;
DartSnmp::ISnmpVariablePtr Variable;
DartSnmp::ISnmpTableRowPtr TableRow;
DartSnmp::ISnmpTablePtr Table;

if(txtQuery.GetWindowTextLength() == 0)
  {
  ShowErrorMessage("Enter variable name");
return;
  }
  
  
CString strQuery;
txtQuery.GetWindowText(strQuery);
txtOIDqry.SetWindowText(Oid);


pManager->Message->Reset();
  AddVariable(strQuery);
//Variable = Variables->GetNext(_bsrt_t(strQuery));
//AddVariable(Variable);
pManager->Send();

Oid = (char *)MibVars->GetOIDFromName(_bstr_t(strQuery));

//Table = Variables->GetTable(_bstr_t(Oid));
//strOid = Oid + ".1";
TableRow = Variables->GetTableRow(_bstr_t(Oid));

COleVariant vi;
vi.vt = VT_INT;
vi.iVal = 5;
try{
Variable = TableRow->Item(vi);//Some problem is here
}catch(_com_error e)
{
ShowErrorMessage(e.HelpContext(), (char *)e.Description());  
}
strOid = Oid;
Oid += ".0";
if (strcmp(Oid,".0")==0){ShowErrorMessage("Truy van nay khong co trong csdl");}
else {
txtOIDqry.SetWindowText(Oid);

txtResult.SetWindowText(Variables->Item((COleVariant)Oid)->Value);
//sprintf(Result,"L:%s",TableRow->RowIndex);
//sprintf(Result,"L:%d",Variables->Item();
//txtCount.SetWindowText((CString) Result);
txtCount.SetWindowText(TableRow->RowIndex);
//txtCount.SetWindowText(Variable->Value);
if(txtResult.GetWindowTextLength() == 0)
  {
  ShowErrorMessage("Not found any value!");
return;
  }

UpdateData(FALSE);
}
//ReadTabe();
//ShowErrorMessage((char *)(Variables->Item((COleVariant)Oid)->Value));


Could anyone help me or give me example code, plzzz.

I think you posted this in the wromg forum. You appear to be using the SNMP Tool, not PowerTCP Pro. That being the case, the sample agent and manager both have excellent examples of how to manipulate tables.
