what...?
I never asked any one to do my assignment....???? It could be a part of assignment but not the whole assignment...??????? But it is not any assignment...i am just startin teaching myself IP...so its a step1. Yeh but to get started i read this question somewhere...
I did find this info myself aswell...d only reason i put this up was bcos i was not sure of the different methods ...later i found out that bilinear interpolation is one of d complex method...so to make sure i ws right i put up a question here......And its always better to take some pre info before you start working over any new area and thats wt i did.. I am starting up with Image processing , speech processing and stuff...And i guess its right to ask some one experienced like urself....who could push me to the right direction....I mostly work over C#.net and recently only i started with MFC n all...
Anyway from next time i would mention what all info my google friend gave me and in what area i am confused...
Thanks for replying to my post...Problem solved.....

does anyone know how to copy data from one listbox(several columns) to another one?
Thanks In Advance;

If this is .NET, then the listboxes have an Items property. If it's not .NET, you'r in the wrong forum

This is the C++/CLI forum. Try the Visual C++ forum, but first try doing a little research. You should ask a question which explains what you've tried. The fstream class is the best way to read a file, and you can read a file word by word with it.

I have declared :friend ostream& operator<<(ostream& out,Complex& c);
but why the error says:

"The C++ / CLI is for managed and mixed-mode C++ programming only " says the sticky post at the top of the forum. If you read that post, you'll see that it's for exactly what the name says - managed C++ and C++/CLI. This is C++ that uses the .NET framework. The visual C++ forum is for straight C++ questions.

Hi,
in C# it's possible to get a handle to a process by doing:
Process[] p = Process.GetProcesses();
and checking each process in 'p' to find a specific one by its using 'ProcessName' property.
Does someone now how to that in C++ to search for a specific process ?
Thanks a lot !
Pat.

In managed C++ you do it the same - it's the same .NET Process class.

Assuming that you mean in standard C++, you're in the wrong forum.

One of my co-workers has had an interesting problem with an application that does lots of text processing. The text processing takes a long time to complete once kicked off (it runs on several gigs of data).
When doing a basic UI for it he set a button on a form that would start this long process (didn't use a background worker, its running in the UI's thread). At this point when watching the processes memory usage it was increasing very fast (around 3 MB's per second).
Then an interesting observation was made ... if a message box was shown after the initial processing had started, the memory usage would go down to a normal level and then for the rest of the processing it would hold solid.
The only way that makes sense to me is if the garbage collector wasn't actually freeing the memory for some reason, until the message box appeared. My guess is that this has something to do with the fact that the processing was being hosted in the UI's thread and not in a worker thread.
We created a console application to do the same processing and it has a stable amount of memory use for the entire time it takes to run.
Has anybody here seen anything else like this where UI threads cause garbage collection not to clean things up ... or at least have an idea of what the main cause of this problem is?

after creating the new dialog (IDD_GET_PROFILE) and build the project i am getting the error
as
ID of the new dialog is not defined.
and if i click on the error it is pointing the
enum { IDD = IDD_GET_PROFILE };
in the .h file of the project.
the id is defined automatically in the resource.h file
where else we need to define the ID?
how to solve the problem?

This question should be on the C++/MFC board, not the managed C++ board.
The compiler needs to know what the value of IDD_GET_PROFILE is at the point of the enum
declaration. The resource editor usually puts these in resource.h so make sure you've included
that file somewhere before you try to use IDD_GET_PROFILE.

My code caused an _CrtIsValidHeapPointer Assertion failure. Microsoft has a solution( Initialization of native global objects requires CRT (C RunTime) startup routine).
This Solution requires
1. Set Linker\Advanced\Entry Point to "" (empty string)
2. Set Linker\System\Subsystem to Not Set
It allows the application and Form to run but an annoying console window appears.
I need help removing this console window or a better way than Microsoft's solution.
Please Help. Thanks.

It seems to me that should be set to /SUBSYTEM:WINDOWS. Don't know if that'll work though

If you set it to Windows the CRC is not loaded. I tryed.

Did setting it to WINDOWS automatically change the Linker\Advanced\Entry Point setting?
For a forms app, the Linker\Advanced\Entry Point setting is "main" and the Linker/System/Subsystem is WINDOWS.
For a Win32 app, Linker\Advanced\Entry Point is WinMainCRTStartup (or wWinMainCRTStartup for
unicode) and the Linker/System/Subsystem is WINDOWS.
So, it seems to me, you need Linker\Advanced\Entry Point set to WinMainCRTStartup (or
WinMainCRTStartup), the Linker/System/Subsystem set to WINDOWS, and change your "main" to
"_tWinMain" (or whatever the appropriate WinMain prototype is these days ) ...
WinMainCRTStartup will call a "WinMain", not "main".

Changing the entry point to WinMain did not work but Changing it to the following removed the console window.
int APIENTRY _tWinMain(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPTSTR lpCmdLine,
int nCmdShow)
{
Thanks for the tips.

Cool!

I said change to WinMainCRTStartup, not WinMain. 
That's probably what entry point is being used if your _tWinMain() is getting called.

Hi all,
I have a component dll compiled as /clr (mixed), I cannot put a break point in any module,
could anyone suspect how to debug it?
Notice that:
The startup project is written in C# and it enables debugging for unmanaged code.
In the build configuration for the sicky dll:
Debugging/Attach property is set to true.
Linker/Debugging/Generate Debug Info property is set to true.
Linker/Debugging/Generate program databse file --> (the same name of the dll).pdb
The optimisation options are set to default.
Regards,
HZ

Hello,
Using this macro: _ASSERT_EXPR couses a compilation error at VS2005 compiler.
Do you know any other macro which can replace this one?
At crtdbg.h:
/* Asserts */
/* We use !! below to ensure that any overloaded operators used to evaluate expr do not end up at operator || */
#define _ASSERT_EXPR(expr, msg) \
(void) ((!!(expr)) || \
(1 != _CrtDbgReportW(_CRT_ASSERT, _CRT_WIDE(__FILE__), __LINE__, NULL, msg)) || \
(_CrtDbgBreak(), 0))
Thanks a lot!
