Hi gurus,
Could anyone tell me how to make an IM system that's compatible w Yahoo! Messenger? I am searching for something about its NW protocol, port... So pliz give me some links and/or documents...

Hi, I am looking for some online work/project. I have expriences in C/C++/Windows programming, SQL and ASP for web programming.

Yeah, but I think it's not because it's C written (C++ is C written, too :rolleyes: ), rather WinAPI is designed not only for C++, but also for C, VB... those don't have function overriding

Thanks friends.

Yes, I just wonder wich way is better (faster) for my app, a binary-search algorithm like yours or the database's algorithm? If the two are equal, I guess it's better to use the database's algorithm...

Hi gurus,
If I have a large database, like a dictionary with hundreds of thousand words, and I have 2 ways of organizing data, one is making my own data structure & algorithm, other is using a SQL...

As far as I know, data synchronization is necessary only when there's "write-to-data" action. Read-only data (includes function) does not need to be synchronized.

Hi AlonHes, memory allocated functions are the same, VirtualAlloc just gives you some more low level options.
This code below outlines the layout of a virtual address space (0 - 0x7FFFFFFF), It also...

Hi teleplayr, pliz read more about GetWindowThreadProcessId and GetCurrentThreadId's documentation :D. GetWindowThreadProcessId returns both Process ID and Thread ID of a specific window, while...

Regardless of how many physical memory u have, ur process has about 2GB (on NT/2K/XP) of virtual address space. A memory request first finds if there's any contiguous block of the requested size...

Basically HANDLE is a UINT value, sometime it's a pointer, sometime it's a index... More detail, u have to know what object is. Maybe an article in MSDN - 'Give me a handle, I'll show you an object'...

Win API is just for generic purposes. If u want more, I think you should search for some graphic library, or write one for yourself.

Well, I have 6 years of C experience, too, but it's nothing more than a number. I believe I know all C's syntax (or at least know where to find them ;)), but of course, (C) programming is not that....

I dont know if there's a function like that. How about imitate it by making ur own 'alpha-blitting' function? There're alot of 'alpha-blitting' algorithms on Google.

Your hdcMain is a common DC and there's no guarantee for its attributes between function calls. For your case I think u should use Private DC by specifying the CS_OWNDC window-class style.
Another...

Could anyone tell me the difference between Managed C++ and C#? They're both based on .NET, aren't they, but which one is the heir of our beloved C/C++? And why choose MC++ but not C#?

So in this case what about C/C++? As the technology & internet grow up, peformance and effectiveness become minor, while less development time and platform-independent are more important. Just think...

Yes, it's possible. I remember in the Petzold's "Programming Windows" fifth edition there's a example that's similar to ur situation.

I think u should convert mouse's co-ordinates to client co-ordinates first.

u can also use GetBitmapBits()

There's several ways to do this, here is one (DLL) that works fine on Win9x/NT/2K/XP. The SetMyHook(HWND my_window, HWND subclassed_window) function subclasses the 'subclassed_window' in another...

I think there's some way to subclass another process' window?. Anyway, we can't rely on a thread/process handle to verify if a window is closed. Process can have multiple threads, and thread can have...

U can also subclass that window then intercept its WM_DESTROY message.

I think there's at least one way to do this.
With __cdecl convention, the caller take the responsibility to setup and clear the callee's params. Looking at this in the caller:

@OReubens: We seem to misunderstand each other. Actually, I think there're not so much things to do with this method (as u said). Consider the folowing:
-Get the window under cursor (by...
