I believe you would have to subscribe to MSDN for that? An alternative is to download the platform SDK, it comes with help files on the Win32 APIs that's pretty much all you need.

The Microsoft Print Dialog appears and I can change the number of copies to something other than 1 but I will only get 1 copy. I thought the number of copies behavior was determined by the Print Dialog box. Do I need to set somthing up to enable multiple copies? Buck Buck Create Visual Studio Win32 Project Programmatically iddqd51510-Jul-07 10:11 iddqd515 10-Jul-07 10:11  I wanted to create a number of Visual Studio projects with the same settings and add various files to them. They're going to be native C++ Win32 projects. Unfortunately I don't see how to do this... http://msdn2.microsoft.com/en-us/library/ms228767(VS.80).aspx includes details on how to do this for C# and VB.NET projects but not VC++ (although I don't really understand the OnConnection method in the examples). As I understand it VC++ uses a different project template structure from those two languages. I couldn't find any more details beyond that though. I dug around in the Visual Studio directory for awhile looking for analogous files for C++ project templates but couldn't find anything but wizards (not the zips and other files I need). It seems like if I could just get past the hurdle of creating the project files I could get this working. Does anyone know if this is even possible? I was going to just create my own template type so I could easily find the directory and files but then I found out VC++ doesn't even support the 'Export template...' option in the file menu. Re: Create Visual Studio Win32 Project Programmatically Perspx10-Jul-07 11:12 Perspx 10-Jul-07 11:12  I'm not sure I don't really use VS much (I find it much slower than other C/C++ compilers ) If you can't do it from VS, you could write an application to do this.. You could just have a basic dialog box with some settings in it, and then a number of template project files (just ordinary .txt files or something) which are copied to the chosen directory when all of the settings have been set.. This method would also allow for more flexibility.. Hope this helps! --PerspX "Nowadays, security guys break the Mac every single day.

There is one unintuitive consequence of this implementation: Process IDs under Windows NT are actually handles into a dummy system table—that is, a table that does not associate its handles with any objects. If you create a process and store its ID away, then after termination of the process, the ID may be recycled for other types of global objects. You therefore cannot use process IDs to uniquely identify processes. This article mentiones that the only kernel objects are drivers or something that are invisible to application. How does it stand correct when compared to mutexex, semaphores etc which it assigns to as Executive objects Re: Handles to objects DevMentor.org10-Jul-07 10:30 DevMentor.org 10-Jul-07 10:30  you might want to get your hands on a copy of "Programing Application for MS Windows" by Jeffrey Ritcher! You seem to be asking a lot of similar question on this board and this book would definitely help you, it talks about about keneral objects and handles and describes what pseudo handles are, etc.... you might also want to look at DuplicateHandle( ) API on MSDN you get an idea of handles and their properties for a lack of a better work.

If you use Win32 API commands they are stored in a DLL somewhere (kernel32.dll for the DeleteFile() API), which are packaged with Windows anyway.. hence you save space and make the program more efficient --PerspX "Nowadays, security guys break the Mac every single day.

Re: Delete file Perspx11-Jul-07 5:37 Perspx 11-Jul-07 5:37  Well, yes, dynamically linking to msvcrt.dll would solve this problem but otherwise the linker links the CRT functions into the executable (i believe anyway :p).. --PerspX "Nowadays, security guys break the Mac every single day.

What kind of coding mistakes cause unexpected exits? TBC_DEV10-Jul-07 9:28 TBC_DEV 10-Jul-07 9:28  I have a C++ dll (native using MFC), it is used from a few different applications. It works much of the time and has no memory issues that Purify can see. But the dll sometimes exits for no reason. No error is reported, it is not a crash or lockup. Since the Dll exits, it causes the application that uses it to exit too. Having no error reported, closing the forms, and being intermitant makes this difficult to debug. Any advise about what to look for in the code that typically causes this type of behaviour (other than forgetting to return)? Yes, the debugger could help but I have not been able to reproduce on a development PC yet. TBC Re: What kind of coding mistakes cause unexpected exits? Perspx10-Jul-07 9:36 Perspx 10-Jul-07 9:36  Sorry if this is pretty unhelpful but you could (and this would be PRETTY laborious) open a file stream and write data to it when certain tasks are performed in the DLL and also (if you can) write a message to the file when the DLL exits to determine what has happened.. I'm pretty sure it's not a memory buffer overload.. This would result in the application crashing, not just exiting.. However I'm not certain so a memory issue could be the problem. Sorry I can't be of more help, but I don't have any of the source code to see for myself.. Hope this helps! --PerspX "Nowadays, security guys break the Mac every single day.
