CComBSTR Memory Leak Anders Molin15-Oct-01 0:57 Anders Molin 15-Oct-01 0:57  I have a problem with CComBSTR's. I create them using new, work with them a bit, pass them to a COM interface with string->Detach(), and after that I delete them with delete. Every string leaks 8 bytes Can anyone tell me why? - Anders Money talks, but all mine ever says is "Goodbye!" Re: CComBSTR Memory Leak Michael Dunn15-Oct-01 8:59 Michael Dunn 15-Oct-01 8:59  Once you call Detach(), the CComBSTR object no longer manages the string, so the leak you're seeing is probably the contents of the string. Pass the string as (*string) which will call CComBSTR::operator BSTR to do the conversion. --Mike-- http://home.inreach.com/mdunn/ "The Earth is doomed." -- Rupert Giles your with and Re: CComBSTR Memory Leak Anders Molin15-Oct-01 9:50 Anders Molin 15-Oct-01 9:50  Nope, it's exactly 8 bytes for each string, no matter how long they are... If I call Copy() it the same I'll try the (*string) tomorrow at work... - Anders Money talks, but all mine ever says is "Goodbye!" How to allow the user to choose language and... Joan M15-Oct-01 0:46 Joan M 15-Oct-01 0:46  Hello, I'm trying to make my last program easier and more powerful, in order to do this I would like to allow the user to choose the language that the program use, there's only a problem: I don't have any idea of how to begin... what should I know? the other thing I would like to do is to prepare the same program to work with and without touch screens, then I would like to be capable to redimensionate some controls in order to allow the fingers work as the mouse pointer. Should I create two kinds of dialog for each window? (one for the touch and the other for the normal screen?). As always thank you very much. Re: How to allow the user to choose language and...

My question is how would I go about doing this? Do they use a SplitterWnd to split the left and right panes? and if so is the toolbar on the lef just a custom view that draws icons vertically? I want to change the pane on the right depending on what is clicked on the menu in the left pane. ie if you click the hierarchy icon then a tree view will appear in the right pane and if you click the users icon then a list view will appear on the right. I am thinking of making it an SDI app and just swapping the views depending on the users selections. Does this make sense to do it this way? i found an article that outlined how to make an outlook style menu on codeguru http://www.codeguru.com/menu/contentmenu.shtml but this uses a dialog resource to shape the menu. Im guessing outlook uses a custome view which is what i will have to implement i guess. Unless anyone knows of an easier way.. Thanks for any help Ash Re: Can someone put me on the right track? Rob Caldecott15-Oct-01 3:27 Rob Caldecott 15-Oct-01 3:27  I implemented an Outlook UI using the popular BCG library - dead easy and there is also an "Outlook SDI" sample that ships with the source. Visit http://www.bcgsoft.com for more info. Basically, you start with a splitter window, split vertically into two panes, with the Outlook bar view on the left. The right hand pane contains another splitter window which is split horizontally allowing a "list" view and a "preview" view.

Daniel Visan14-Oct-01 23:00 Daniel Visan 14-Oct-01 23:00  You only have to look in MSDN at CString::CString , CString::GetBuffer , CString::ReleaseBuffer 1)LPCSTR->CString CString constructor---CString::CString( LPCSTR lpsz ); 2)CString->LPTSTR LPTSTR GetBuffer( int nMinBufLength ); Make sure you understand the ReleaseBuffer method.

Daniel Visan14-Oct-01 21:45 Daniel Visan 14-Oct-01 21:45  Is there anybody knows how to find the names of the shared files and folders on a remote computer like "network neighborhood" does? "FindFirstFile" function doesnt seem to work. Maybe the path i use is not correct or it doesnt work at all on the subject. Ex: FindFirstFile("\\Comp_name\\fold_name\\*.*" ,.....) PS: And more... Im very curios to find out how "network neighborhood" manages to obtain those shared files and folders? What's the mechanism it use? Thank you. Re: How to find out remote files?

Daniel Visan14-Oct-01 22:01 Daniel Visan 14-Oct-01 22:01  FindFirstFile(\\\\Comp_name\\fold_name\\*.*" ,.....). I still dont get how this function works... Re: Sorry, stupid question... NormDroid14-Oct-01 22:12 NormDroid 14-Oct-01 22:12  FindFirstFile returns a handle, so one's code would look like this... (a snipped from my production code) WIN32_FIND_DATA fd; CString sQualifier = sPath; sQualifier += _T("\\*.*"); HANDLE hFindFile = FindFirstFile(sQualifier, &fd); BOOL bBool = hFindFile == INVALID_HANDLE_VALUE ? FALSE : TRUE; if (!bBool) return FALSE; int i=0; while (bBool) { if (!(fd.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY)) { listFiles.insert(FileList::value_type(fd.cFileName, fd)); i++; } bBool = FindNextFile(hFindFile, &fd); } Norm Almond Chief Technical Architect FS Walker Hughes Limited Re: You missunderstood me. My fault. Daniel Visan14-Oct-01 23:27 Daniel Visan 14-Oct-01 23:27  I knew all the things you tell me.Thanx, anyway.In fact wanted to ask something else... I meant how does a function on my computer like FindFirstFile managed to find out the shared resource on a remote computer? From where that function collects theese informations? What network protocol theese function use? Why do i ask all theese questions? Just because i want to write a project... I want collect from my LAN how many information i can. All theese informations i want to monitorize on my computer. If i write a socket based client on every computer and a server on my computer then the problem is solved. BUT, I WANT TO WRITE A SINGLE APPLICATION ON MY COMPUTER IN ORDER TO GATHER INFORMATION FROM ALL COMPUTER IN MY NETWORK, ABOUT:IP ADDRESS, PROCESSES, MAC ADDRESS, FREE SPACE ON HARDDRIVES, AND MANY MANY OTHERS. Of course, i make use of SNMP (MIBII) BUT ONLY LOCAL. I dont know how to access SNMP information on remote computer. I hope i wasnt boring and i made myself clear. Re: You missunderstood me. My fault. markkuk15-Oct-01 0:41 markkuk 15-Oct-01 0:41  I think the Windows Networking (WNet) functions could be what you need. See the Platform SDK docs under Networking and Directory Services/Network Management. Re: You missunderstood me. My fault. Daniel Visan15-Oct-01 1:01 Daniel Visan 15-Oct-01 1:01  WNet is exactly what i was thinking about! i discovered WNet looking at "Computers enumeration" article. Now that you told me about WNet i have more trust in it. I have to say my WNet knowledge is zero. Did you actualy use WNet on your projects? Do you know some articles except MSDN ones? Thank you a lot! A serious problem on the subject now... Daniel Visan14-Oct-01 22:38 Daniel Visan 14-Oct-01 22:38  FindFirstFile("\\Comp_name\\fold_name\\*.*",... ) works fine. But FindFirstFile("\\Comp_name\\*.*,...) doesnt return anything... Then i started the "Command Prompt" and type "dir \\comp_name" and i got the following message:" The share name was not found" !!!!! i also mention that in Command prompt the following works fine: "dir \\comp_name\\fold_name" !!!! If i type in Command prompt "NET VIEW \\comp_name" i get exactly what i want. Try yourself if you think i'm jocking. So, how do i find out the parent directories on a remote computer (in my application, of course)? Thank you... again: ATL 14-Oct-01 21:21 14-Oct-01 21:21  I created by Wizard ATL COM DLL that import my MFC extention DLL(from type: base Dialog) in my ATL. Please check my steps (describes below) and tell me if I miss something. (because I dont success create instance of it from client program) ------------------------------------------------------------------------ 1. I opened project: ATL COM Wizard. [DLL] [MFC Support] 2. I inserted to the library that created the file : MyMfcDll.dll and attached to the ATL project the files : MyMfcDll.h , MyMfcDll.lib 3. I Added by wizard ATL class [MyClass] [single] [dual] 4. I added by wizard method [ShowMfcDialog] to IMyClass and fill it so : ___________________________________________ #include "MyMfcDll.h" STDMETHODIMP CMyClass::ShowMfcDialog() { AFX_MANAGE_STATE(AfxGetStaticModuleState()) CMyDialog dlg; //from the imported dll dlg.DoModal(); return S_OK; } ______________________________________________ and that's all ! What is missing ? I will be greatful if you will help me ! ATL - Addition to the question 14-Oct-01 22:27 14-Oct-01 22:27  HI !

Why no one answer me ? 15-Oct-01 0:28 15-Oct-01 0:28  Re: ATL - Addition to the question Michael P Butler15-Oct-01 1:27 Michael P Butler 15-Oct-01 1:27  Is this the same machine that you compiled the ATL dll on. If not, then have you registered the dll. regsvr32 <dll filename> Michael
