take ownership 24-Jul-01 0:43 24-Jul-01 0:43  I want take ownership of a file from a process running as administrator, but the administrator dont have any permit in the file. I can do this from the explorer (file property, security, advanced, owner) but with win32 security API i cant do it. With SetSecurityInfo or SetNamedSecurityInfo the result is error because i dont have permits. If i can do it from windows explorer, why not from security API? thanks in advance Mario Changing title bar in SDI mode ...

Tomasz Sowinski -- http://www.shooltz.com Problem with CWinApp::Run. 24-Jul-01 0:13 24-Jul-01 0:13  Hi All, I have Overridden the CwinApp::Run function in my code and I have called some of the functions which does my desired work.There is no problem with these functions as they execute properly. But when the control tries come out of the CwinApp::Run function it enters the MFC code and crashes there. The main problem is in the File "WinHand.cpp" (Within Visual Studio). In that file the following function gives the problem. void CHandleMap::DeleteTemp() { if (this == NULL) return; POSITION pos = m_temporaryMap.GetStartPosition(); while (pos != NULL) { HANDLE h; // just used for asserts CObject* pTemp; m_temporaryMap.GetNextAssoc(pos, (LPVOID&)h, (void*&)pTemp); // zero out the handles ASSERT(m_nHandles == 1 || m_nHandles == 2); HANDLE* ph = (HANDLE*)((BYTE*)pTemp + m_nOffset); // after CObject ASSERT(ph[0] == h || ph[0] == NULL); ph[0] = NULL; if (m_nHandles == 2) { ASSERT(ph[1] == h || ph[1] == NULL); ph[1] = NULL; } delete pTemp; // virtual destructor does the right thing } m_temporaryMap.RemoveAll(); // free up dictionary links etc } In the above function there is a line which says ASSERT(ph[0] == h || ph[0] == NULL); It is crashing at this particular. I am not able to understand why exactly it is giving this problem. Does anyone have any idea about the problem. Any help is hugely appreciated. TIA Srinidhi. Re: Problem with CWinApp::Run.

Tomasz Sowinski -- http://www.shooltz.com Re: Problem with CWinApp::Run. 24-Jul-01 2:46 24-Jul-01 2:46  Hi, Thanks for your response. Here I have pasted the code. m_pMagicControl is my main UI class which puts up a complex UI. int CMAGICOPTApp::Run() { // TODO: Add your specialized code here and/or call the base class if (theApp.m_pMagicControl->Open()) { theApp.m_pMagicControl->ShowUI(TRUE, theApp.GetMainWnd()); } return CWinApp::Run(); } Could you smell something?? TIA srinidhi Re: Problem with CWinApp::Run. Tomasz Sowinski24-Jul-01 2:54 Tomasz Sowinski 24-Jul-01 2:54  Could you smell something?? Not exactly. I think you should ensure that it's a 'magic control' that causes the crash. What happens when you comment out the ShowUI call? Tomasz Sowinski -- http://www.shooltz.com Re: Problem with CWinApp::Run. 24-Jul-01 9:52 24-Jul-01 9:52  HI, Thanks for your interest, I traced the problem for sometime. So this is the result I got from it. Now, I dont override CWinApp::Run(). I moved all the UI initialization to InitInstance (). Now, the application gets initialized properly, but it crashes inside CMenu::DeleteTempMap(). Do you why this happend? TIA Regards Srinidhi mcisendcommand() & sampling rate? zecodela23-Jul-01 23:25 zecodela 23-Jul-01 23:25  hi all, can anyone tell any command should be used for setting sampling rate for recording? regards, jim THIS ? Gérald Mercet23-Jul-01 22:38 Gérald Mercet 23-Jul-01 22:38  I would like to know if someone could answer me to simple problem: We suppose that we create a class MyClass where there are methods(method1(), method2()...) where one have to use another method of MyClass. For example, suppose that method1 need of method2 in its implementation, how could i do that? thanks in advance gerald Re: THIS ? Christian Graus23-Jul-01 23:01 Christian Graus 23-Jul-01 23:01  I don't understand ? You want to call method1() from inside method2() ? What's the problem ? Just do it. If you mean from another instance of the class, make the method static and you'll only have one instance of the method across all classes.

Gerry23-Jul-01 23:13 Gerry 23-Jul-01 23:13  Yes, you can do that....You need to decide if the methods are public or private! Gerry. Re: THIS ? Gérald Mercet23-Jul-01 23:23 Gérald Mercet 23-Jul-01 23:23  thanks for your help Re: THIS ? Christian Graus23-Jul-01 23:16 Christian Graus 23-Jul-01 23:16  Absolutely. You could also go return method1(); at the end of method2 if you wanted to. It's completely available to you.

Gérald Mercet23-Jul-01 23:24 Gérald Mercet 23-Jul-01 23:24  thanks for your help! how pointers work? 23-Jul-01 22:07 23-Jul-01 22:07  This Visual C++ is rather strange to me and I like to know about pointers... I´ve been working with Visual C++ only a two months and now this hole thing is just banging the head in the wall... So how these pointers are used? Meaning that where you construct the pointers and when you use them? There were before a question, where somebody disclaim a working with directories etc. And there is pointer pListoBox-> How you generate this kind of pointer in the code? Here is code which I copy / pasted earlier discussion (This code is written Carlos Antollini): while(haveFile) { havefile = finder.FindNextfile(); if(finder.GetFileName().Find(".") == -1 && !finder.IsDirectory()) pListBox->AddString(((LPCTSTR)finder.GetFileTitle()); } Re: how pointers work? Gerry23-Jul-01 22:52 Gerry 23-Jul-01 22:52  Pointers can be used anywhere in the programs you write. These are to save memory on startup and are faster to access and easier passed between methods. We can allocate memory, use the resources, & deallocate the memory, keeping our system in good shape. So, if we had. someFunction() { CListBox myListBox //Allocate memory on stack. myListBox.AddString(""); //Call method. }//Object destroyed on exit (out of scope). or we could have someFunction() { CListBox* pListBox = new CListBox; //Allocate memory on stack. pListBox->AddString(""); //Call method. delete pListBox; //Destroy memory, give the system back the memory on the heap. } We can easily pass our pointers to other functions, saving time, no overhead in copying objects, copy by reference or copy by value, value is slower. Hope this helps a bit....The best way to get experience with pointers is to use. Gerry. Re: how pointers work? 23-Jul-01 23:23 23-Jul-01 23:23  I think you can go read "A Beginner's Guide to Pointers" which written by Andrew Peace. You can find this article in this site, it is quite helpful. http://www.codeproject.com/cpp/pointers.asp Hope this can help you... Re: how pointers work? 23-Jul-01 23:39 23-Jul-01 23:39  Thanks for advises! I go and look that article... And thanks very much of that code before, it clears also this thing much!
