void CSerialRecieveDlg::OnBtnAutosend() { // TODO: Add your control notification handler code here if(!m_ctrlMSCommCOM1.GetPortOpen()) AfxMessageBox("please open the port!"); else { CCreateName Dlg; CString TB_Name; CString mstr; if(Dlg.DoModal()==IDOK) { TB_Name=Dlg.m_TableName; } m_pRecordset->Close(); //// create a new table in SQL mstr.Format("IF NOT EXISTS (SELECT * FROM sysobjects WHERE name = '"); mstr+=TB_Name; mstr+="') CREATE TABLE "; mstr+=TB_Name; mstr+=" (ID INT,FangWei TEXT,FuYang TEXT,QingXie TEXT)"; try { m_pRecordset->Open(mstr.AllocSysString theApp.m_pConnection.GetInterfacePtr(), adOpenDynamic, adLockOptimistic, adCmdText); } catch(_com_error *e) { AfxMessageBox(e->ErrorMessage()); } SetTimer(1,500,NULL); } } when dibug to the end, appear an ERROR about "stackoverflow" what is the problem??

The problem would appear to be that you've posted a C++ question in the SQL forum. Please choose a more appropriate one. Just because you've used the word Recordset in the post doesn't actually make this a database issue. It's still C++.

Deja View - the feeling that you've seen this post before.

excuse me but i have found that when i do nothing to the database in a WM_TIMER function, there is no error, but just if i do something, for example: void CSerialRecieveDlg::OnTimer(UINT nIDEvent){ CString str; CCreateName Dlg; CString TB_Name; TB_Name=Dlg.m_TableName; str.Format("SELECT * FROM "); str+=TB_Name; try { //先关闭已经打开的记录集对象 m_pRecordset->Close(); //根据新的Sql查询语句，重新打开记录集对象 m_pRecordset->Open(str.AllocSysString(), theApp.m_pConnection.GetInterfacePtr(), adOpenDynamic, adLockOptimistic, adCmdText); } catch(_com_error *e) { AfxMessageBox(e->ErrorMessage()); } m_pRecordset->MoveNext(); CDialog::OnTimer(nIDEvent); } there is a runtime error, The problem is that i do not know it is a database problem or a C++ problem??
