Re: Learning Visual C++ Christian Graus24-Mar-01 0:30 Christian Graus 24-Mar-01 0:30  Buy MFC Unleashed from SAMS. C++ Unleashed is also a good read, and Visual C++ Unleashed is all right, but I don't own it, because by the time I saw it I was past it ( no, I do not work for the publisher ;0) The MFC Answer Book by Eugene Kain is a must, it answers about 60% of the questions you have been asking, and a lot you're likely to. VC++ MFC Extensions by Example is similar, but a lot of the answers in that book are just plain ugly ways of doing things. However, it *does* answer things Eugene's book does not. The best book I bought recently would be 'Mastering Algorythms in C' by Kyle Loudon, or 'Windows Graphics Programming' by Feng Yuan, both thorough in there coverage of their respective areas. Basically, I'm saying you should get over to FatBrain and break out the plastic. And make sure you don't think you can *master* C++, all you can do is join us all on the journey.... And of course, keep asking questions ;0) Christian The content of this post is not necessarily the opinion of my yadda yadda yadda. To understand recursion, we must first understand recursion.

I want this program I am making to allow the people who are hosted to connect to my FTP but not go above the folder they have been assigned. This Xceed thingy has a liscence on it and I dont even know how to set it up. If you know of an easier way or another way of making an FTP client like this, please reply to this message. Or if you know how to set up this Xceed thing, please...I require your assistance!

Manfred Ramosch23-Mar-01 6:17 Manfred Ramosch 23-Mar-01 6:17  Does anybody know how to retrieve a WIN-message that indicates the scrollbar of a Listbox having been scrolled up or down? I have a modeless dialog with 6 listboxes (side by side) that get the V-Scrollbar automatically when there are more Items to display than the LBs can show at once. All lists do always have the same lenght due to the behaviour of my data. What I want is to keep the LBs synchron - I mean that the TOPINDEX is the same in all my boxes. Even when I move the scrollbar I wanna keep them in sync. That works fine with the LBN_SELCHANGE for every box: void CMyClass::OnSelchangeList01() { int iResult; iResult = m_List01.GetCurSel(); m_List01.SetCurSel(iResult); m_List02.SetCurSel(iResult); m_List03.SetCurSel(iResult); m_List04.SetCurSel(iResult); m_List05.SetCurSel(iResult); m_List06.SetCurSel(iResult); iResult = m_List01.GetTopIndex(); m_List01.SetTopIndex(); m_List02.SetTopIndex(); m_List03.SetTopIndex(); m_List04.SetTopIndex(); m_List05.SetTopIndex(); m_List06.SetTopIndex(); } The same I do for OnSelchangeList02(); OnSelchangeList03(); OnSelchangeList04(); OnSelchangeList05(); OnSelchangeList06(); I can select whatever I want in whatever LB - with the mouse or the arrow-keys. The TopIndex of every LB is the same and the selected items (highlighted) appear side by side. So far so good - ONLY after moving the vertical scrollbar the LBs are out of sync because I cannot get any message of the scrollbar showing me that the visual state of the LB has changed and though giving me the possibility to use the SetTopIndex()-function like above in the LBN_SELCHANGE message handler of my LBs... I tried it with CWnd::OnVScroll() but I couldn't find a way to retrieve a notification from my Listbox-scrollbars out of this function... All those nice SB_BOTTOM, SB_TOP, SB_THUMBTRACK - and I cannot access them...... So any Ideas out there...? Manfred --- Programming is knowing... Re: CListBox and Scrollbar...

I really need help! win95 exe's jump to win2000 - (Painful) Gerry23-Mar-01 5:40 Gerry 23-Mar-01 5:40  We have win95 exe's written in c++ & mfc...these work well on win95, but keep blowing up with "Abnormal Terminations" on win2000. How best can I migrate my VC5 & MFC code to Win2000 ????? Would a win2000 dev pc with devStudio install & a recompile do any good? Cheers Gerry. Re: win95 exe's jump to win2000 - (Painful) Kannan Kalyanaraman23-Mar-01 18:55 Kannan Kalyanaraman 23-Mar-01 18:55  I'm not expert in these things, but let me share my experience. From my personal experience, you need to work it(compile ... devet.. testing) on a nt or 2k machine. The problem is most of the code would work without a hickup in 95/98 but almost always will end up blowin up in NT / 2K. Most of the problem could be to do with uninitialized memory (in my case that was the problem) so while do the debugging in NT/2K machine ... you have more chances of spotting the bug.

This might be because you're relying on the way Win95 returns or processes data, which is different under NT. Or it might simply be because NT and Win95 create different kinds of call stacks and therefore exposes a bug that just happened to work under 9x. In any case, you should debug on the platform you're trying to target. Getting the original URL of a Temp. Internet File 23-Mar-01 5:11 23-Mar-01 5:11  Hi, Is there a way to get the original URL of a file stored under the "Temporary Internet Files" folder (I am looking for the value of the column "Internet Address", as displayed in Windows Explorer). Thanks, J. AfxBeginThread and EndThread Vickie23-Mar-01 4:25 Vickie 23-Mar-01 4:25  Dear all, I'm writting a MFC program that enables the user to enter the URL, and then press "Start" button to start downloading the html from that URL. So I have create a WorkerThread to handle the downloading process so that the user can press "Stop" button to terminate the downloading process. After successful or unsuccessful downloading of html, it should call a Text-to-speech function to speak to the user about the status of download. However, the text-to-speech function cannot work when there is another thread running. I have tried to create another thread to call the TTS function, but it failed too. My question is :where does the thread return when it finished?? Is there anyother method to call my TTS() function when the thread is finished? Here is my program: // myappdlg.cpp static UINT workerthreadcontrol ( void * pRTclass ) void myappdlg.OnStart() { downloadHTML(); } void downloadHTML() { ..... CWinThread* pWorkerThread; pWorkerThread = AfxBeginThread ( workerthreadcontrol, this, THREAD_PRIORITY_NORMAL, 0, CREATE_SUSPENDED ); m_Startbtn.EnableWindow( False ); m_Stopbtn.EnableWindow( True ); pWorkerThread->ResumeThread(); ..... } UINT workerthreadcontrol( void * pRTclass ) { myappdlg pDlg = (myappdlg*) pRTclass; pDlg->WorkerThreadProcess(); return 0; } void WorkerThreadProcess() { doing downloading......... } // Where should I put this function??? void TTS( LPCTSTR Text ) { Speak out Text..... } Thanks a lot for your help.... Best Regards, Vickie Re: AfxBeginThread and EndThread Michael Dunn23-Mar-01 15:45 Michael Dunn 23-Mar-01 15:45  If I understand, your problem is you need to know exactly when the worker thread has quit? Right before the return in the thread function, post a message (WM_APP would do) to your dialog to tell the UI thread that the worker thread is done. --Mike-- http://home.inreach.com/mdunn/ The preferred snack of 4 out of 5 Lounge readers. URGENT: Convert CHAR dimension into BSTR 23-Mar-01 3:58 23-Mar-01 3:58  Hi everybody: How could I convert a CHAR dimension into a BSTR??? I have: BSTR *alt; CHAR Msg[200]; Thanks in advance: Javier Re: URGENT: Convert CHAR dimension into BSTR Gerry23-Mar-01 5:57 Gerry 23-Mar-01 5:57  You could use wcscpy or BString, CString...I think..... Gerry. Re: URGENT: Convert CHAR dimension into BSTR 23-Mar-01 9:21 23-Mar-01 9:21  To finish up your example: _bstr_t *alt; //this is changed a bit char Msg[200]; strcpy(Msg, (char*)(*alt)); //to go from _bstr_t to char[] alt = new _bstr_t(Msg); //to go from char[] to _bstr_t _bstr_t wraps up the BSTR data type
