How can I override CPropertySheet::RemovePage(int nPage) in a derived class? mfc_surfer1-Dec-03 21:35 mfc_surfer 1-Dec-03 21:35  I have a CPropertySheet derived class; I need to implement the CPropertySheet::RemovePage(int nPage) Would you tell me how I can do that? Re: How can I override CPropertySheet::RemovePage(int nPage) in a derived class? Kene1-Dec-03 22:19 Kene 1-Dec-03 22:19  I will like to believe u probably need to do some things before removing the page. Try implementing these 2 mtds: void CMyPropertySheet::RemovePage(CPropertyPage *pPage) { //do ur stuff... //...... //finally, call the parent mtd... CPropertySheet::RemovePage(pPage); } void CMyPropertySheet::RemovePage(int nPage ) { //do ur stuff... //...... //finally, call the parent mtd... CPropertySheet::RemovePage(nPage ); } Goodluck!

Re: How can I override CPropertySheet::RemovePage(int nPage) in a derived class? mfc_surfer1-Dec-03 22:39 mfc_surfer 1-Dec-03 22:39  Thanks for the reply! I've done the same but the problem is that it throws an exception, I think it's due to another code I've put in the caller method. How Can I pass a dynamic message from a parent class to its derived class? mfc_surfer1-Dec-03 21:31 mfc_surfer 1-Dec-03 21:31  I have 3 classes that are derived from each other as: class A class B: public Class A class C: public class B I've used a dynamic message in class A which resizes the controls on it. I want to resize the controls on classes B and C as well and I've put BEGIN_DYNAMIC_MAP() ... END_DYNAMIC_MAP() on them but the controls are not resized in classes B and C. Could you help me? Re: How Can I pass a dynamic message from a parent class to its derived class? Kene2-Dec-03 0:31 Kene 2-Dec-03 0:31  I don't know about.. BEGIN_DYNAMIC_MAP() ... END_DYNAMIC_MAP() I think it should be similar to BEGIN/END_MESSAGE_MAP. I'll also assume ur classes (i.e A,B,C) can recieve messages. MFC docs says " if a message can't be matched in a derived class's message map, the framework also searches the message map of its immediate base class". So check to ensure u have something like these... //for class B BEGIN_MESSAGE_MAP(B, A) //.. END_MESSAGE_MAP //for class C BEGIN_MESSAGE_MAP(C, B) //.. END_MESSAGE_MAP search MFC doc for more details goodluck! What would life be without programmers and salesmen? Re: How Can I pass a dynamic message from a parent class to its derived class? mfc_surfer2-Dec-03 0:54 mfc_surfer 2-Dec-03 0:54  yes BEGIN/END _DYNAMIC_MAP()is something like BEGIN/END_MESSAGE_MAP that has been defined in a class that my A class is derived from that. By the way, I do have //for class B BEGIN_MESSAGE_MAP(B, A) //.. END_MESSAGE_MAP //for class C BEGIN_MESSAGE_MAP(C, B) //.. END_MESSAGE_MAP but nothing happens when resizing the classes B and C, and I couldn't find anything useful in MFC docs except what you have mentioned Re: How Can I pass a dynamic message from a parent class to its derived class? Kene2-Dec-03 2:11 Kene 2-Dec-03 2:11  You can try calling a virtual mtd (e.g doresize) from ur class A message handler. Remember to implement the mtd in B and C. OR.. If class A is a CWnd kind-of (which I feel it is), then implement the usaul MFC's overidables like 'OnSize' e.t.c. good luck! What would life be without programmers and salesmen? plzzz help! Re: How Can I pass a dynamic message from a parent class to its derived class? mfc_surfer4-Dec-03 0:30 mfc_surfer 4-Dec-03 0:30  I've implmented OnSize() in child classes and the page itself is resized but the controls are not I'm using this code to resize the controls and it works in the parent class: BEGIN_DYNAMIC_MAP(CPropPageTabular,CPropPageItemize) DYNAMIC_MAP_ENTRY(IDC_STATIC_REP_OPTIONS, mdResize, mdResize) ... END_DYNAMIC_MAP() Re: plzzz help! Re: How Can I pass a dynamic message from a parent class to its derived class? Kene5-Dec-03 3:50 Kene 5-Dec-03 3:50  Can I see the details of ur OnSize implementation?

I need to get index of recordset from my database, but do not know how to do it. If anyone can help me, please, leave your answer here. Thanks in advance, bilas mailt:keeper_@km.ru Re: how to get index from database(MS ACCESS) David Crow2-Dec-03 10:01 David Crow 2-Dec-03 10:01  You did not indicate whether you were using MFC or not, but if so, CDaoRecordset::GetCurrentIndex() and CDaoRecordset::GetAbsolutePosition() come to mind. Five birds are sitting on a fence. Three of them decide to fly off. How many are left? bi-directional scrolling in CADORecordset bilas1-Dec-03 19:51 bilas 1-Dec-03 19:51  I want to have a recordset with bi-directional scrolling, but when I connected to my database like following: >CString strConnection=_T("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=module.mdb"); >if(m_db.Open(strConnection)) >{ > m_rec=CADORecordset(&m_db); > if(m_rec.Open(_T("main"), CADORecordset::openTable)) > MessageBox("Table 'main' is opened "); >} following operation: >m_rec.MoveFirst(); has no effect(does not works). But using class CRecordset it works: >m_rec.Open("SELECT * FROM main", CRecordset::dynaset); What a mistake I made using CADORecordset? Thanks in advance, bilas. mailto:: keeper_@km.ru Multithread CAsyncSocket problem?? dddv1-Dec-03 18:48 dddv 1-Dec-03 18:48  I write one multithread program to download file using CAsyncSocket. I got one problem. Can anyone help me out? I derive my thread class from CWinThread. In thread class I new one CAsyncSocket instance. and create and connect it when It is one thread, it can work normally.when it is 2 threads it can work normally at most. but when thread numbers is large, they will cause exception. at the same time,for per thread, when socket OnConnect arise, it return WSAEADDRINUSE error. I found another problem. when I debug 2 thread. during socket Create call. the socket in the first thread can create normal, but the socket in the second thread, It will cause assert . It means the the m_hSocket has been in socket map. I didn't know why this happen. I think socket map should be thread local. thanks Re: Multithread CAsyncSocket problem?? dddv2-Dec-03 0:38 dddv 2-Dec-03 0:38  I have read this article before. But I didn't want to pass handle between thread, I generate one CAsyncSocket instance for per thread, and do owner job in thread, I didn't detach,attach handle from one thread to another I didn't know if it is possible. Re: Multithread CAsyncSocket problem?? Moak2-Dec-03 0:56 Moak 2-Dec-03 0:56  CAsyncSocket is probaly not what you want to use with multiple threads, but you can use this class to connect multiple sockets (download multiple files) in ONE thread... it works nearly unblocking. Well, with multi threaded networking (if you REALLY need it that hardcore) you might have to use the "naked" socket API... see http://www.ecst.csuchico.edu/~beej/guide/net/ ... or any other API that Microsoft provides (see MFC articles in Code Project). Hope it helps, Moak Re: Multithread CAsyncSocket problem?? dddv2-Dec-03 4:38 dddv 2-Dec-03 4:38  Can you explain why not using CAsyncSocket for per thread? I cannot figure out Re: Multithread CAsyncSocket problem?? Moak2-Dec-03 5:03 Moak 2-Dec-03 5:03  it was not designed for that purpose. it serves as asynchronous networking class: unblocking network access with events when a operation (like connect/read/write) has finished. in theory you could use it in multiple threads, but as far as I remember Microsoft's implementation was not multi thread safe (you get an assert with some functions in a debug build if you still try). Perhaps rethink your network strategy, perhaps you can go single threaded and use CAsynSocket within one thread context (simple application code). However, the class is not very perfect it has some problems with DNS lookups (they block).

Re: If anyone wants too... bilas1-Dec-03 19:50 bilas 1-Dec-03 19:50  try the MSDN library or any other help documents.
