I would create an accelorator, which would disable the esc key and let you give other key combos functions.

I am sorry
I don't understand "and let you give other key combos functions"
What's that meaning?
Can you tell me?

He means that using an accelerator, you can make other key-combinations perform other operations, as well as preventing the dialog from closing. However, Toni78's solution is the best and easiest one.

In the psapi.lib, the function getProcessMemoryInfo() returns a PROCESS_MEMORY_COUNTERS struct.I urgently want to know whether PROCESS_MEMORY_COUNTERS.WorkingSetSize can directly indicate the size of memory a process currently occupies.If it can, the value returned is KB,OR B? If it cannot, how can I get the size of memory a process currently occupies?
I am in emergency and long for any help!Thanks!

WorkingSetSize should be the size of the process that is loaded in RAM in bytes.

I want to add a bitmap as a background to the main Window of SDI document. Can anybody help me what to do? I am really in emergency. I will really appreciate help.

Draw the bitmap first in your OnDraw method of your view. Then, draw the rest of your view. You may have to pDC->SetBkMode(TRANSPARENT) to prevent your drawing from hiding the bitmap.
onwards and upwards...

Can u please provide me the code . I am really not an expert in VC++. That will be really helpful.

I'm trying to make a Help app that is linked to an already funtioning C++ program. The problem I seem to have is that if I change the text of AfxCore.rtf it has an error pop-up when I load the workspace. I have no experience with making a Help app and I'm the one assigned to figure it out. I'f anybody knows what goes on in MSVC++ when it comes to making a Help app, then please help me. The MSDN tutorial is horrid, I can't make heads or tails of it.

Have a look at this website [^] and if that doesn't help, run a search on google on help file tutorials. That's how I learned how to write help file. Hopefully, it will work for you too. It is not difficult at all. You just have to learn what kind of symbols to insert when you create footnotes.
I have a few tutorials and if you can't find anything, give me your email address and I will email them to you. But I have to go through my CDs and find them first.

I am reading "Windows Graphics Programming", by Feng Yuan, and in the beginning he writes his own custom Window class to demonstrate a number of code techniques. It's C++, and looks a lot like the classic style of Petzold (I'm sure many of you are familiar with Petzold). Anyway, he writes two Windows Procedures for his class, one virtual and one static, (this is kind of confusing) so that the Windows system will dispatch messages to the correct message handler (he subclasses his child windows from this class).
Anyway, forget all that, my question is about something else entirely. In his header file for this custom window class, he lists the usual function calls you would make: the two Windows Procedures, constructor(void), destructor, Create, RegisterClass, and sets up the default message loop. Then, and this is what I don't understand, he does this:
BOOL ShowWindow(int nCmdShow) const<br />
{<br />
return ::ShowWindow(m_hWnd, nCmdShow); <br />
}<br />
<br />
BOOL UpdateWindow(void) const<br />
{ <br />
return ::UpdateWindow(m_hWnd);<br />
}<br />
What exactly do those return statements do?
Oh, sorry, m_hWnd is the handle to the Window(type HWND). In his constructor, he does this:
KWindow(void)
{<br />
m_hWnd = NULL; <br />
}

I assume this isn't MFC related code. He is wrapping global Windows API functions as functions within his class. The :: in ::ShowWindow() means call the global function, not one in a class. By wrapping these functions he doesn't need to a) use ::FuncName everywhere and b) doesn't need to pass m_hWnd as the wrapped function does this for him.
Hope that helps.

Neville,
Thanks for the response. And, yes, it is non-MFC code.
The ShowWindow and UpdateWindow calls are standard Win32 functions, I recognize the same calls from Petzold.
But, what I don't understand is: Why return anything? Typically, when creating a window, you just write the same code as above, but without a return statement. I'm thinking that he intends to make the two variables (the HWND and the int type) available for some other potential action, I don't know what.
I realize that it's an insignificant issue, but, his return statements are often of this style (and he never returns a this*). Weird.

Hi NB,
From the ShowWindow() docs:
Return Values
If the window was previously visible, the return value is nonzero.
If the window was previously hidden, the return value is zero.
And for UpdateWindow()
Return Values
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero.
Windows NT: To get extended error information, callGetLastError.
So returning the same value as the wrapped function makes perfect sense to me.

2 questions about VC++:
first, when I close VC++ and then reopen an MFC project in VC++, my resources file is gone...where did it go. I clicked on the .dsw to open my workspace but the resource folder doesn't even show up.
second, I get the following message in my debug window:
"fatal error LNK1104: cannot open file "nafxcwd.lib""
It appears that my library is not linked properly, no? How do I remedy this problem?
tanks much, Dave

From Michael Dunn's C++ Forum FAQ:
2.8: Why do I get an unresolved external on nafxcw.lib or uafxcw.lib? (top)
The files nafx*.lib and uafx*.lib are the static LIB versions of MFC. The files beginning with "n" are the ANSI version, and the files beginning with "u" are the Unicode version. By default, only the ANSI files are installed on your hard drive. If the linker cannot find these LIB files, copy them from your Visual C++ CD to your <vcdir>\vc98\mfc\lib directory.
If those files are not on your CD, then you have an edition of Visual C++ that does not support static linking to MFC. You will need to change your project settings to use the DLL version of MFC. Click Project->Settings and go the General tab. In the Microsoft Foundation Classes combo box, select Use MFC in a Shared DLL.

In MFC, the function AfxGetInstanceHandle returns the instance handle to the dll you are currently in... What is the equivalent win32 API call? I can't seem to find it, but there must be a way... I need it for SetWindowsHookEx parameter inside a dll...
|

I don't think there is one for that. MFC plays a trick by saving the DLL handled at DLLMain, and gives it back to you.
I expect that you need to save the handle somewhere at DLLMain?

Hi.
I am working on a project that features socks v4 and socks v5 communication over winsock. I am using raw winsock. I need to know the format of packages coming and going to a socks server. Here are reference I have read and techniques I have tested.
http://www.faqs.org/rfcs/rfc1928.html
http://jonathanclark.com/diary/firewalls/
Please look over those websites. As you can see, socks server communicate requires a very specific format. In C++, we generally use a structure.
Anyways, I can send packages to the socks server, however, the data that it sends back does not make any sense.
In sum, I need someone who has successful worked with socks using raw winsock to give me an example of how to *interpret* data from the sock server during negotiation.
Thanks,
Kuphryn
