im wanna go down the csv route. i am using the CArchive as follows CFile f; char strFilter[] = { "csv Files (*.csv)|*.csv|All Files (*.*)|*.*||" }; CFileDialog FileDlg(FALSE, ".csv", NULL, 0, strFilter); if( FileDlg.DoModal() == IDOK ) { f.Open(FileDlg.GetFileName(), CFile::modeCreate | CFile::modeWrite); CArchive ar(&f, CArchive::store); ar<< m_Make << m_Model << m_Year << m_Mileage << m_Owner; ar.Close(); } else return; f.Close(); the above is coming out in one cell with a rectangular box after each string how do i get ride of those retangular boxes and have a string in a seperate cell thanks

how did you write the data out thou, i see there is CArchive but doesnt appear to do much!!

im using VC++6 MFC, i want to create and save some data out to a file such as a csv file or even better a excel file. I know of CFileDialog to bring up a save dialog but how do i pump out data in a csv or excel format thanks

thanks all, enablewindow works perfect, dont know why i didnt think of that!! i was trying to the the EN_******** to use with a sendmessage!!

i was wondering how do you grey-out / disable the date time picker, is there a flag that can be changed say using a send message? i have my date time picker as a CDateTimeCtrl type

i am scanning alot of hosts with this app, waiting 2mins for every host would take for ever to scan the network, hence i use the thread timeout of 3secs i just read about _endthread and it appears to work so far. is this a proper solution?

i think i have that working now. A kind of related problem i have is with the code below. This is a part of the code the thread executes, if sucessful all is ok. this thread has a timeout of 3secs. A problem is that the ConnectServer call below takes 2minutes to complete if it cant connect. when this happens the below messagebox pops ups and then the program crashes. is it crashing because the code wants to "return" but there is nothing to return to as the thread has been already killed?? How can i modify it so that it wont crash. A message box doesnt have to be displayed either. many thanks hres = pLoc_test->ConnectServer( _bstr_t(L"\\\\"+strIP1+"\\root\\cimv2"), // Object path of WMI namespace NULL, // User name. NULL = current user NULL, // User password. NULL = current 0, // Locale. NULL indicates current WBEM_FLAG_CONNECT_USE_MAX_WAIT, // Security flags 0, // Authority 0, // Context object &pSvc_test // pointer to IWbemServices proxy ); if (FAILED(hres)) { char error_msg[64]; sprintf(error_msg, "wmi_test: Could not connect. Error code = 0x%x", hres); MessageBox(error_msg , "Error" , MB_ICONERROR | MB_OK); pLoc_test->Release(); return; }

so i use the following to delete a thread from outside?? Does "delete pThread" call ExitThread?? switch(WaitForSingleObject(pThread->m_hThread, 3000)) { case WAIT_TIMEOUT: { delete pThread; break; } case WAIT_OBJECT_0: { // thread has terminated on its own break; } }

sorry, i dont understand, example please thanks

what command do i use to kill the thread thou from outside the thread?

i have a thread that calls the following CoInitializeEx() CoInitializeSecurity() CoCreateInstance() ConnectServer() if the thread isnt successful in 3secs (using WaitForSingleObject(pThread->m_hThread, 3000)) it is closed. what is the best way of killing a thread from outside the thread, i am using TerminateThread() but i dont think this is the best way?? it appears thou that the calls in the thread are not being killed off because if i go to start the thread again CoInitializeSecurity() throws up an error saying that it cant initialize security. so iam assuming it is saying this because the thread wasnt killed off right plz help

so will i get away with using CoInitializeEx() with COINIT_MULTITRHEADED and not having to use marshalling?

hi i have a vc++6 MFC app. in my main i start a thread that connects to the wmi of a host, it uses IWbemLocator *pLoc IWbemServices *pSvc back in the main, once the thread has finished connecting to the wmi of the host, it is queryied but the two global variables above are "empty", this is because you cannot use COM interfaces on multiple threads and each thread must initialize COM itself and onyl use local COM objects afaik. so i think marshalling will have to be used but i dont know where to start on how to implement it please help

thx, that worked can explain why thou?

ok this is what i have.. static UINT CScanDlg::ThreadProc(LPVOID pParam); delcared in the header file AfxBeginThread(ThreadProc,NULL,THREAD_PRIORITY_NORMAL,0,0,NULL); UINT CScanDlg::ThreadProc(LPVOID pParam) { if(wmi(strIP1)) return 0; else return 1; } i get the following error CScanDlg::wmi' : illegal call of non-static member function

thx for the replys i am having trouble implementing AfxBeginThread() void CScanDlg::OnButtonScan() { AfxBeginThread(ThreadProc); } UINT CScanDlg::ThreadProc(LPVOID pParam) { if(wmi(strIP1)) return 0; else return 1; } what is wrong above, sorry about these questions but this is new to me
