- What i am actually trying to do is make
some modifications to the Blender source code
to fix my problems with the buttons and menus being
drawn incorrectly because of driver issues,
but all can be fixed if just the ui goes DX.
PS: The actual 3D window is fine i just want to mix the OpenGL editing with the buttons and menus being drawn with DX

Come on guys. I just need to know if it wont crash my computer with the mix of the two.

 Hi, I am using Visual C++ 6.0 MFC and I have an application where I have a window that allows me to set up some criteria and then click on a print button. 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?

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.

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!

How do I use windbg to find usermode and kernel mode memory leaks.
|
|
|
|

See Toby Opferman's article series here. he'ss really good with using Windbg.

What is the implication of the following from MSDN
Unlike the handles that are maintained by the Win32 USER and GDI subsystem components, handles to native objects under Windows NT are not unique; that is, upon destruction of an object, the corresponding handle may be recycled and will look exactly like the handle to the destroyed object. 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

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.

Hi all, would anyone know what WinAPI you call to delete a file? Or is it standard C++ ? Just curious, thanx in advance!
|
|
|
|

Use the DeleteFile() API see MSDN for the documentation

Heck I will throw in _rmdir( ) which is implemented in the C run-time library and possibly more portable

Note though that adding C run-time commands increases the file size of the executable as these functions actually get compiled into the exe.. 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

Hugh? 
You statically linking too the C runtime libs while dynamically linking to Win32 APIs?!?!. You know the C-RTL also comes in DLL flavours like msvcr80.dll, or msvcrt.dll.
|
|
|
|
|
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)..

In pure c++ or c,there's no such function can delete file,u must use API to do this.

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.

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!

Thanks PerspX for the quick reply. That's what I needed to hear. I thought maybe I was missing another obvious cause of this symptom. File logging was a last resort. It's a fairly complicated dll with only a few public functions. Sorry I can't post any code, but I'm not permitted.

Yeah that's fine it also may help you to sort out any other bugs and even possibly make your coding more efficient

Are you using Threads in your DLL?
Unexplainable phenomenon - The try-catch in main function did not catch exceptions in a dll's thread. The exact same *complete- and silent exit* happened to my app.
It turned out that if a thread in the dll has an AccessViolation, accessing a NULL-element on a primitive-type array or other dangling reference problem, the exception catch of the host-app do not catch the execption in the dll's thread.
I think you should evaluate all array accessing routines and life-span of objects and its pointer contexts. -Or implement a errorlog. But I think by the time you find the faulty pointer or array, you well could've implemented a errorlog.
You should take this problem as a wake-up call for *your code is too complicated*. Debugging Spaghetti is not fun and a errorlog would help.
Hope this helps.

1) What is the difference between handle and pointer in terms of memory. Can my other process(non releated) see a handle/pointer. Lets say if my application has a pointer pointing to some data at at that memory location. Will it be possible for the other application to access that data? How?
2) What will one try to use LoadLibrary which shall load a exe and not execute it?
3) The return value from WinExec, which is a stripped-down version of CreateProcess, is a handle to a Windows NT executive object, whereas an instance handle, the value returned from LoadLibrary, is a virtual pointer.

A handle is an "opaque" data type. You can't make any assumptions about what it is and the
implementation can be changed (in future versions) at any time. A handle could be a pointer, an
index, an atom, etc. A handle is NOT always a pointer.

Each process has its own address space. You could pass a pointer to another process but the
pointer would be useless to the other process. To share memory between processes you could use
something like GlobalAlloc, which allocates memory on the global heap.

You seem to know alot about internal details like that Who cares, both functions are holdovers
from 16-bit Windows.
