Re: Passing a pointer to a char-array Chris Losinger21-Aug-02 4:20 Chris Losinger 21-Aug-02 4:20  can you use a CStringArray, or a vector of CStrings? Though the cough, hough and hiccough so unsought would plough me through, enough that I o'er life's dark lough my thorough course pursue. --Stuart Kidd image effects! Re: Passing a pointer to a char-array fheyn21-Aug-02 4:31 fheyn 21-Aug-02 4:31  thanks for the reply. the char-array items come from SQLBindCol(....) which wants type char. since the database-table is about 40 fields large, I use the char array. After getting all the items filled, I could of course write then to a CString-array but that looks as bad to me as what I've right now. there should be a way to access the array be incrementing the pointer one step at a time.

Re: Passing a pointer to a char-array fheyn21-Aug-02 4:50 fheyn 21-Aug-02 4:50  Great ! almost correct, but it must be cArrayType[20] and now it works like I want it to. thanks Re: Passing a pointer to a char-array Ravi Bhavnani21-Aug-02 5:05 Ravi Bhavnani 21-Aug-02 5:05  Sorry, I assumed you knew what I meant. Try this: typedef char MyArrayType [50]; // MyArrayType is a custom type MyArrayType myArray [20]; // the array /ravi Let's put "civil" back in "civilization" http://www.ravib.com ravib@ravib.com ressource.dll error Mike Mc21-Aug-02 3:15 Mike Mc 21-Aug-02 3:15  All- I just joined this site, because when I get error messages I am often pointed to it during a search. But, I am a virgin when it comes to code. I am getting an error "cannot initialize ressource.dll". I have not installed anything but have lost most of my right-click menu and that error will appear ONCE during every DIFFERENT action. For example: Drag & Drop error, click close and Drag & Drop works without a problem. But, if I get that error with another action AFTER Drag & Drop, then it will reappear the next time I try to drag & Drop. I do not have ressource.dll on my system and wouldn't know what program it belongs to. I want to "ease" my way into being able to do simple debugging and I hope this will be the place. Thanks in advance Mike Mc Re: ressource.dll error Mike Mc21-Aug-02 8:22 Mike Mc 21-Aug-02 8:22  Problem Solved. I had a shell compression program called Iceows (formerly ARJ Folder). I had disabled the commands and that was what caused ALL of my problems. But, here's the kicker. The error was "Cannot Initialize ressource.dll" and this program doesn't install it. Now, I should be able to just uninstall the p[rogram completely. Then I can lurk and learn. My 4th system and I cannot keep up with the latest codes. Mike Mc F1 invoke WinHelp, which I don't want it to lucy21-Aug-02 3:07 lucy 21-Aug-02 3:07  I got a sample Dialog based MFC program. I made some modifications to it, one of them is: when F1 is pressed, show the HTML help file. But when I run it, after the HTML help file was shown, a message box pop up with caption of "Windows Help", and the message itself is: "Cannot find the S:\TRANSFER\lwang\Antialiasing\Debug\ASIST3D.HLP file. Do you want to try to find this file yourself? Yes No". It seemed to me that the default function for accelerator key "F1" is still being invoked somewhere in the program. How can I get rid of it? Thank you very much for any hint! Re: F1 invoke WinHelp, which I don't want it to -Dy21-Aug-02 3:13 -Dy 21-Aug-02 3:13  Have you checked the message map? Probably that - unless that's how you made your mod? Dylan Kenneally London, UK Re: F1 invoke WinHelp, which I don't want it to lucy21-Aug-02 3:39 lucy 21-Aug-02 3:39  hmm, there is a default function for ID_HELP in the App class. Getting rid of that line solves this problem. Thanks! Re: F1 invoke WinHelp, which I don't want it to Tomasz Sowinski21-Aug-02 3:22 Tomasz Sowinski 21-Aug-02 3:22  MFC translates F1 into ID_HELP command. You're invoking Html help in response to what event? Tomasz Sowinski -- http://www.shooltz.com "Yields falsehood when preceded by its quotation" yields falsehood when preceded by its quotation. Re: F1 invoke WinHelp, which I don't want it to lucy21-Aug-02 3:34 lucy 21-Aug-02 3:34  Thanks for the fast response. I'm invoking Html Help in response to menu item File->Keys. And I assign F1 as the accelerator key to this menu item. I add the following lines to my dialog cpp in its message map declaration: ON_COMMAND(ID_HELP, OnFileKeys) And remove the line for ID_HELP in the App class. Thus solved the problem. Thank you very much again! RasDial Anonymous21-Aug-02 3:07 Anonymous 21-Aug-02 3:07  is it possible to use the RASDial Function without knowing the szEntryName + password + username, and just connect with the default settings to redial a lost Modem connection . thanks Re: RasDial Victor Vogelpoel21-Aug-02 5:13 Victor Vogelpoel 21-Aug-02 5:13  You can download a free RasDial class at Dundas. Works for me... http://www.dundas.com/products/downloads/register.asp?ProdID=4[^] or go to the dundas site, then to downloads and then to TCP/IP downloads. VictorV CSocket -> not thread-safe ? Niko Tanghe21-Aug-02 3:07 Niko Tanghe 21-Aug-02 3:07  According to my experiences and some sources on the net the MFC class CSocket does not seem to be very thread-safe. Creating the sockets (listen sockets & accepted sockets) in the main-thread and using them in another thread gives troubles... So I tried to create all sockets in the thread function. After calling AfxSocketInit() in the thread function (I don't know if this is correct ...) Everything seems to be fine, But the virtual functions OnAccept(), OnReceive(), ... are not called. The attach/detach trick is not an option, because both mainthread and other thread use the sockets. How should I handle this problem ? Any help appreciated. Greetings, Niko Re: CSocket -> not thread-safe ? Rob Caldecott21-Aug-02 3:54 Rob Caldecott 21-Aug-02 3:54  Why can you not use Attach/Detach? I use this in a multi-threaded socket app. e.g. I have a thread that uses a socket that listens on a port. When an incoming connection arrives it creates a new thread and passes the thread the socket handle: void CListenSocket::OnAccept(int nErrorCode) { CSocket socket; Accept(socket); CAcceptThread* pThread = (CAcceptThread*)AfxBeginThread( RUNTIME_CLASS(CAcceptThread), THREAD_PRIORITY_NORMAL, 0, CREATE_SUSPENDED); pThread->m_hSocket = socket.Detach(); pThread->ResumeThread(); } BOOL CAcceptThread::InitInstance() { m_pSocket = new CServiceClientSocket; m_pSocket->Attach(m_hSocket); } Faith. Believing in something you *know* isn't true. Re: CSocket -> not thread-safe ? Niko Tanghe21-Aug-02 5:51 Niko Tanghe 21-Aug-02 5:51  We don't want to use many thread, because there will be some 10.000 connections on that server. The accepted connection is added to a pool. 1 thread polls all connections and performs some actions on the sockets. On the same time the main thread is also able to do some interaction on some sockets. I guess using attach/detach everytime when needed wouldn't be good idea.

Re: Debug Application Jason Henderson21-Aug-02 3:30 Jason Henderson 21-Aug-02 3:30  1) Copy Dependency Walker (Depends.exe) to a floppy. 2) Find out his OS version. 3) Go to a computer with that OS and your application installed. 4) Copy Depends.exe to that machine and run it. 5) Open the app that caused the error (MyApp.exe caused an invalild page fault...) in depends 6) In the bottom panel, find the base address of the module the error occured in 7) In calc.exe, subtract the base address from the memory address of the error 8) Sort column 2 row 2 panel in depends by the Entry Point column 9) Find the closest match to your calculated result in #7 in the entry point column 10)This address should correspond with the function your error occured in (look in the function column) Its not perfect, but it works most of the time.
