How to read a file that is open by ... craigk16-Jul-02 11:25 craigk 16-Jul-02 11:25  ... another app exclusively? I need to be able to open a file for "reading" that is already opened exclusively by another app, that is writting to that same file. I've used tools that do this, but can't figure out how it is done. Can someone point me in the right direction? Thanks much! craig knutson dakotaknut@yahoo.com craigk DAO in VC++ not working. a3gupta16-Jul-02 11:15 a3gupta 16-Jul-02 11:15  Hello, I will really appreciate any input on the following problems. I am implementing the Database operations using MFC .. and using DAO. The problem is when the program goes to get the data, it just quits. THIS HAPPENS ONLY ON SOME COMPUTERS. It just simply quits! This was happening when I was implementing ODBC in the same program. The screen where it is supposed to display the data, when it goes to the screen .. it just disappears and terminates. My database is in .mdb format. The other problem is that it says "Unrecognized database format" if I write my database in Access 2000. I am wondering if there are some win registry entries that are not being updated or something. Thank you very much for your time and help ! Sincerely, Anjum. Re: DAO in VC++ not working.

Martin Ziacek16-Jul-02 22:33 Martin Ziacek 16-Jul-02 22:33  I am not sure, if this article Q236991 will solve the all your troubles, but at least second one should be rectified. Re: DAO in VC++ not working. Schnemar16-Jul-02 22:35 Schnemar 16-Jul-02 22:35  Hi, I had the same problem with "Unrecognized database format" and I solved it like this: In InitInstance() of my App-Class I put the follwing line: AfxGetModuleState()->m_dwVersion = 0x0601; That was it. For further Information see the follwing Article on MSDN: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnmsj00/html/cpp0100.asp I hope that helps you. MS Modeless Dialog udayGovekar16-Jul-02 10:29 udayGovekar 16-Jul-02 10:29  Hi, My application interacts with the device through RS232 Data sent/Received over the port should be displayed while still programming is communicating with the device. For this I created one modeless dialog class with edit member variable Now Consider one packet tobe sent, contents of this packet should be assigned to the dialog class member variable and it should be updated but when I tried todo so my application is crashing. But if I do with Modal Dialog it is working fine. can anyone please explain me Thanks in advance Uday Re: Modeless Dialog includeh1016-Jul-02 10:56 includeh10 16-Jul-02 10:56  too many about communication. does ur app crash from comm or modeless dialog box? normally, modeless must be global or class member, can not be local as modal one because it returns at once then local modeless dialog box is destoyed. hope hit ur point includeh10 Re: Modeless Dialog udayGovekar16-Jul-02 18:38 udayGovekar 16-Jul-02 18:38  It is crashing at modeless, further I have not created this as local. When communication is happening I wnat to show the data sent/received for which I am using the modeless. If I assign the packet(CString type) to my edit variable(CString type of modeless dialog class), it is getting crashed.When I tried to assign it to the local variable it is not crashing adding a new configuration NickOne16-Jul-02 10:27 NickOne 16-Jul-02 10:27  Hello everybody, I am not sure how hard this is, but I want to add a new configuration based on some #define code. I am trying to follow Paul DiLascia's tutorial on building a File viewer. So this is my question. He adds a code that turns his SDI bitmap loader into an MDI bitmap loader. I want to do this too. He adds a lot of #ifdef _MDI statements that convert the code to MDI. You have to add a new configuration to do this. How do I add a configuration to get this #ifdef _MDI to work? I tried to add a new configuration, but it never runs the code in the #ifdef _MDI, but always goes to the #else statements. I added a AfxmessageBox to make sure, and the message box always says "SDI Compilation" and never "MDI Compilation." How would I go about adding his configuration? Thanks so much, NickOne Re: adding a new configuration Joaquín M López Muñoz16-Jul-02 12:00 Joaquín M López Muñoz 16-Jul-02 12:00  If you already created a new configuration for MDI mode, go to the Project Settings for it and look for the preprocessor section. Add _MDI to the list of predefined macros. Joaquín M López Muñoz Telefónica, Investigación y Desarrollo Re: adding a new configuration NickOne17-Jul-02 8:10 NickOne 17-Jul-02 8:10  Thank you! I appreciate the response. I actually had figured it out after some battling. I am not too familiar with the user interface, so I didn't know this option existed. But you are absolutely correct. Thanks again for helping me out, I always appreciate it very much.

Joaquín M López Muñoz16-Jul-02 12:03 Joaquín M López Muñoz 16-Jul-02 12:03  before i study for hrs, hope u give me one more word: can i do it (should be yes, i guess)? Should be yess. The code needed is nevertheless so little that you'll be better off pasting it into your app and seeing the results. Joaquín M López Muñoz Telefónica, Investigación y Desarrollo C++ socket or java socket, who is better? includeh1016-Jul-02 9:43 includeh10 16-Jul-02 9:43  i tested both c++ and java socket (under windows), got similar results: i.e. max 45 sockets in a single machine (clients and server are in the same PC). i think there is no different between c++ and java socket from efficent, speed or capibility view. do u have different thinking or experieces? includeh10 Re: C++ socket or java socket, who is better? Joaquín M López Muñoz16-Jul-02 10:15 Joaquín M López Muñoz 16-Jul-02 10:15  You are basically right, Java and C++ sockets are mapped to system sockets, so they behave pretty much the same. Joaquín M López Muñoz Telefónica, Investigación y Desarrollo CStatic question Anonymous16-Jul-02 9:33 Anonymous 16-Jul-02 9:33  Suppose, you have a wizard that has bitmap on top of every page. Then, you want to add a title to the bitmap of every page. You don't want to modify the bitmap itself, rather add a text using something like CStatic. How would you do it? I have tried adding a transparent CStatic and it doesn't work. I have played with other options on CStatic and they don't seem to work either. Any ideas? thanks Re: CStatic question Joaquín M López Muñoz16-Jul-02 10:12 Joaquín M López Muñoz 16-Jul-02 10:12  Transparent CStatics aren't really that static. You can use (for instance) Norm Almond's CLabel to have true transparency. Joaquín M López Muñoz Telefónica, Investigación y Desarrollo Help with ActiveMovie 4!! PLEASE!!
