MFC Multiple windows (pages) Jens Christiansen2-Sep-04 1:40 Jens Christiansen 2-Sep-04 1:40  Hi, could someone help me ! I would like to create multiple windows (or pages) when creating my mainframe in my Windows MFC project. How do I do that ? With regards Jens Christiansen Re: MFC Multiple windows (pages) RChin2-Sep-04 1:47 RChin 2-Sep-04 1:47  If you're talking about creating multiple views of your document, you can always use the splitter control. Check out the MSDN documentation[^] that has a couple sample code on this.

VikramS Re: MFC Multiple windows (pages) Jens Christiansen2-Sep-04 8:56 Jens Christiansen 2-Sep-04 8:56  This is working, but then I don't go through my MainFrame which is controlling my toolbars and menu's. So would it be possible to create the windows (pages) and control then in the MainFrame ?

So I'm basically messing around trying to get this device installed manually, before I add it to the setup script. I have a problem though... After my latest attempt, I get this error message in the device properties box: "This device is not working properly because Windows cannot load the drivers required for this device. (Code 31)" Does anyone know if there's a log somwhere or somthing which I can use to find out what exactly went wrong?

Don't try it, just do it! Precompiler Directive Anonymous2-Sep-04 1:12 Anonymous 2-Sep-04 1:12  Hi What are the advantages/disadvantages of using #define or pany precompiler directives? Thanks in adavnce Ram Re: Precompiler Directive Joel Holdsworth2-Sep-04 1:39 Joel Holdsworth 2-Sep-04 1:39  The precomiler is both a blessing and a curse. It can really help you work round obstacles, but it can often have problems with compatibility with other compilers. The main statments like #define, #ifdef, #ifndef, #endif and so on will work on any compiler. Others like #pragma once will only work on MSVC. #define is useful in defining constants, and in activating and deactivating sections of code. However if you plan to use #define for constants, it's always better to use a global C constant instead: const unsigned int MyValue = 100; Because the syntax checker can dig you out of problems this way. Also, try and avoid macros - use inline functions instead because again you may end up with crazy inexplicable compiler errors. Joel Holdsworth Re: Precompiler Directive Henry miller2-Sep-04 3:21 Henry miller 2-Sep-04 3:21  The main advantage is with proper use of the precompiler directives you can win the Internation Obfuscated C code contest The other time you will see it is in header files, to make sure that the header isn't accidently included twice. The rule is if there is a way to do what you want without using the precompiler do it, but sometimes you don't have a choice. If you don't know what the IOCCC is, check it out when you are prepared to be confused. Good programs will enjoy it, for the joke, the chance to learn some really stupid code, and to test the knowledge of C.

How do I use VC++ 6.0 to detect the interrupt and do the necessary processing? Is there any examples or articles that I can refer to? Thanks. S1189216G Re: Interrupt in VC++ RadioShark2-Sep-04 8:00 RadioShark 2-Sep-04 8:00  Hi, Use SDK coming with your card. Otherwise, you should write own Windows driver using DDK. Windows API doesn't allow working with the interruptes directly. Sincerely Yours, RadioShark Re: Interrupt in VC++ Puah2-Sep-04 14:43 Puah 2-Sep-04 14:43  To RadioShark, Thanks for your reply. Any examples, links or article that I can go to? Can I use C code interrupt handler? If yes, how should be done? S1189216G Re: Interrupt in VC++ RadioShark2-Sep-04 18:28 RadioShark 2-Sep-04 18:28  Working with the interruptes and IOports directly is allowed in MSDOS. So, you can use C or C++ for MSDOS. In MS Windows, you should write own driver. You will find the examples of driver in DDK.

I need to distinguish between a restart and a shutdown. Is there a way to do so? Thanx in advance. Best regards, Andrea
