Connection Question 6-Oct-01 10:10 6-Oct-01 10:10  Excuse me that I post question in this forum, but I didn't find an answer for it. Does anybody know how to connect two PCs with Window 200 via cros-over cable. 10x, Re: Connection Question Shadi Al-Kahwaji7-Oct-01 0:32 Shadi Al-Kahwaji 7-Oct-01 0:32  Hi, I do know, you need the following: HW 1. Eithernet card on the two PCs 2. Cross Cable ( make sure that what you have is a cross cable) SW 1. Create a new LAN Connection on the first PC, and give it a dummy IP address, for example 10.10.0.1. 2. Create a new LAN Connection on the second PC, and give it a dummy IP address, this time you have to use the same presvious IP except the last number, for example 10.10.0.2. 3. Add the same user name and password on both PCs. 4. Share a folder on the PC that you want to access. Note: You have to restart both PCs after you change the IP addresses, and make sure that you don't login to any domain, you just login to the Local Machine. Enjoy , ShadiK. Shadi Al-Kahwaji How to create modal windows? Pipe6-Oct-01 5:09 Pipe 6-Oct-01 5:09  Hi there! I know that this could be done with the DialogBox(...) macro and the DialogBoxParam(...) function. However, does anybody know a solution to make windows created via CreateWindow[Ex](...) modal?

Do you want to bypass the main message loop or your goal is just to disable one window when other is active? Tomasz Sowinski -- http://www.shooltz.com Re: How to create modal windows? Pipe8-Oct-01 6:51 Pipe 8-Oct-01 6:51  the second one ... I have an application that at a certain moment could consist of dozens of windows that allow the user to manipulate many things at once. The Dialog is to choose a folder from the local drives to extract some items to. While the user chooses I want all those other windows to be inaccesible. Since the application supports DLL's that are not neccessarily mine I'm not alwas able to say how many windows are to be disabled. Thats why I need a thread-modal Extract-To dialog ... Do you know any workarounds or good solutions to this? many thanks for incoming advice ... --------------------------------------------------- - Pipe - Re: How to create modal windows? Tomasz Sowinski8-Oct-01 7:18 Tomasz Sowinski 8-Oct-01 7:18  You basically have two options now: 1) find out all windows (EnumThreadWindows) in the thread and disable them (EnableWindow(hwnd, FALSE)). The only non-disabled window will behave like modal dialog 2) control the thread's message queue. Monitor all input messages (WM_KEYxxx, WM_LBUTTONDOWN, etc) messages and don't dispatch them if they are addressed to window you want to disable. Personally, I'd try version 1.

Fazlul Kabir8-Oct-01 7:12 Fazlul Kabir 8-Oct-01 7:12  Hey Pipe: See MSDN for these two functions: ::RunModalLoop and ::EndModalLoop MFC uses these two functions to make dialogs modal. You may want to look MFC's implementation in CDialog::DoModal() also. \\vc98\mfc\src\dlgcore.cpp // Fazlul Get RadVC today!

Tomasz Sowinski -- http://www.shooltz.com Re: How to create modal windows? Fazlul Kabir8-Oct-01 14:18 Fazlul Kabir 8-Oct-01 14:18  Oh, I thought the windows he was playing with were derived from CWnd. Nevertheless, he can probably copy and paste thse two functions to his project (can be found in \\mfc\src\wincore.cpp.) They are actually not that big and not that difficult to understand either. The ::RunModalLoop() implements an infinite loop that continuously checks windows message queue by calling ::PeekMessage(..). If it finds EndLoop() is called, then it breaks the loop. I believe WTL takes a similar approach to implement Windows modality too. // Fazlul Get RadVC today!

How can i make the image still visible even if it is overlapped ? I tried changing the mode but it does not work ? Parag Re: bitmap image problem Christian Graus6-Oct-01 10:00 Christian Graus 6-Oct-01 10:00  The background of which image ? How are they stored ? How are they being shown ? Is it erased on screen, or in memory ? What mode are you changing ? Christian As I learn the innermost secrets of the around me, they reward me in many ways to keep quiet.

Oracle and ADO Mr_Byte5-Oct-01 23:19 Mr_Byte 5-Oct-01 23:19  I need to access oracle through my VC++ program can I use ADO? if I can is there is any code or tutorial to explain that or any other ideas Thanks MR.Byte Re: Oracle and ADO Michael P Butler6-Oct-01 7:02 Michael P Butler 6-Oct-01 7:02  I'm currently using ADO to access an Oracle database with VC++. Have you used ADO before? What are you trying to do? It is pretty much standard ADO stuff apart from a few gotchas with the Oracle stored procedures. Michael Re: Oracle and ADO Mr_Byte6-Oct-01 7:14 Mr_Byte 6-Oct-01 7:14  I read about it ,but I didn't realy need it before thats why I ask for help MR.Byte Re: Oracle and ADO Michael P Butler6-Oct-01 7:24 Michael P Butler 6-Oct-01 7:24  I access my oracle database via an odbc connection using ADO. A good starting point for ADO is http://www.codeproject.com/database/caaadoclass1.asp This is the connection string I use for my oracle ADO connection object. sConnect = _T(" DRIVER={Microsoft ODBC for Oracle}; SERVER=servername; UID=user; PWD=password"); One additional thing, make sure you've got the latest version of MDAC installed. hope this helps, Michael Re: Oracle and ADO Mr_Byte6-Oct-01 8:16 Mr_Byte 6-Oct-01 8:16  Thanks MR.Byte Exit When Enter Key is Pressed 5-Oct-01 21:50 5-Oct-01 21:50  i'm a beginner in visual c++,i would like to know how can i prevent my application from Exiting when Enter Key is pressed at start-up. Re: Exit When Enter Key is Pressed Derek Lakin5-Oct-01 23:08 Derek Lakin 5-Oct-01 23:08  Assuming your application is a dialog-based application, then pressing the enter key has the effect of pressing the default button, whichi by default is the OK button, which will cause your button to exit. If you don't want it to exit, either don't press enter, or change which button is the default one. If I'm way off then let us know a bit more about the nature of your application and I'm sure we can help Derek Lakin. Salamander Software Ltd. Re: Exit When Enter Key is Pressed 7-Oct-01 15:59 7-Oct-01 15:59  derek, its a dialog-based application,i removed the OK button and placed the Exit function inside the Menu. Re: Exit When Enter Key is Pressed | mProject |6-Oct-01 0:10 | mProject | 6-Oct-01 0:10  There is one another solution. You can override OnOK function. Simply add function: void CYourDialog::OnOK() { } And your problem disappearing... -------------------------------------------------- Say Whatever You Know.

You might check in OnOK if return has been pressed, so it works only by pressing the button, but it's just as easy not to make it the default button.

I use "SendMessage" in View class and catch the message with its handler in Doc class. But it does not work. But when I I use "SendMessage" in View class and catch the message with its handler in View class, it works perfectly. How to catch the message in Doc class? Thanks. Maer Re: user defined message Michael Dunn5-Oct-01 21:31 Michael Dunn 5-Oct-01 21:31  My MFC's a bit rusty, but I believe documents can only handle WM_COMMAND messages. A document isn't a window, so you can't send it arbitrary messages. A doc can handle WM_COMMAND, but only because MFC handles the message routing itself. As an aside, you should define your own messages as WM_APP+x, not WM_USER+x, because some common controls use WM_USER. No control uses WM_APP so you are guaranteed not to run into any conflicts. --Mike-- http://home.inreach.com/mdunn/ "Listen you footwarriors, can you hold down a bit with the firing?
