I figured that, but having checked the Win32 functions, MFC reference, and run-time reference and finding nothing, I gave up. I should have just looked in MSDN[^], though actually finding anything there is often a challenge.

I'm trying to retrieve information through software about the system's chipset. Things like the brand, model#, revision# etc...
Would somebody be able to point me in the right direction? 
Thanks heaps!

Hey all
Just wondering if anyone knows of an "easy" way to get the computer's HOST name? (The host name of the computer that is running the application?)
Thanks!

I've been reading a handy book I bought a while ago, but never got around to opening, called Microsoft Windows 2000 API SuperBible. It obviously was never a best seller, as I got it for $15 on the discount shelf, but it's full of thousands of API descriptions and examples in C++. Neat stuff I can get into real mischief with, like BlockInput(TRUE) and ExitWindowsEx(EWX_FORCE, NULL). It even identifies which OS versions (Win2K or Win9x) each call applies to, and points out usage differences if they exist.
Now that WinXP is the OS of the week, to what extent does XP add to, or invalidate the Win32 API that was current as of Win2K?

Hi!
I think it maybe a question difficult to answer. But I hope there are some people share the same experience with me will give me some hint.
I find one dll project very weird.
There are some functions in the dll to be export. They are declare with _declspec(dllexport).
But some function(about 5%) can't be find in the generated dll. (I used ultraedit to search for the name in the dll binary)
I finally find out it have some relation to its parameter. for example
int funcNoUse(long lRegionID)
{
return 0;
}
will be ok, it's generated in the dll.
But if i change it to
int funcNoUse(long lRegionID, long nPoints, float* pY, LPCTSTR szFlags, int makeCopy)
{
return 0;
}
it will not exist in the dll.
I really don't know what's up. I have test it on two computer one with VS7 and another with VS7.1 have the same result.
any idea?

Sounds like you be being a victim of "Name mangling". This is something the C++ compiler does so that overloaded functions with the same name but different parameters can be properly resolved by the linker. You can force the compiler to turn of "Name mangling" for a specific function by using extern "C" in the function declaration.
extern "C" int funcNoUse(long lRegionID, long nPoints, float* pY, LPCTSTR szFlags, int makeCopy)

Message digest is something similar to digital signature. I would like to insert it in my mp3 id3 tag. There is an extended header that has variable length in id3 tag. How can I add message digest in the extended header using visual c++?
|
|
|
|
|
what ? say that again ?
AFAIK, you can pretty much insert anything in an mp3 ID3v2 tag. have a look at http://www.id3lib.org[^] for more info on id3 tags.

I have 3 checkboxes, if i put 1st one under group, does that mean that i can only select one box at any one time, just like in radio buttons? Also, for radio buttons, are they assigned button1 = -1, button 2=0, button3=1 and so forth? cause i need to use if else statements for the different buttons.

No. Check boxes are completely independent.

No. They start from 0 (button 1=0, button 2=1 etc...)

I have a very primitive question on C++.
If I want include a library I use #include
say, #include <iostream> , iostream header file all I/O functions are declared.
But Including a Standard C++ header does not introduce any library names into the current namespace. For that we have to use
using namespace std;
What does this mean? Does it mean in namespace std all the functions in standard library files are defined and that's why we need that?

Yes.
Having the using statement means that you don't have to qualify each individual std name e.g. std::cout << "Hello world" << std::endl

hi 'binayak',
so, to help you, i would say that the C++ standard includes some classes and functions into the std namespace.
In fact, be careful to the diference between the folowing directives :
<font style="color:green;">
<font style="color:blue;">#include</font> <iostream>
<font style="color:green;">
<font style="color:blue;">#include</font> <iostream.h>
so, if you use std:: and you don't want to call it each time you want a function defined inside (for example cout << "Hello world !" instead of std::cout << "Hello world !") you'd prefer the command line
<font style="color:blue;">using namespace</font> std;
Clearly, it tells to the compiler that it will have to look inside the std:: to find the called function.
you could also do this if you don't want all the standard namespace to be used implicitly :
<font style="color:blue;">#include</font> <iostream>
<font style="color:blue;">void</font> main (<font style="color:blue;">void</font>) {
<font style="color:blue;">using</font> std::cout; <font style="color:green;">
cout << "Hello world !";
}
hope that's more clear now

No. The iostream.h library is only the Microsoft fake of STL iostream and now is obsolete.
so, if you use std:: and you don't want to call it each time you want a function defined inside (for example printf("Hello world !") instead of std::printf("Hello world !")) you'd prefer the command line
printf is a function from stdio.h, not iostream.

We have an application running on Windows 2000 that uses shell commands to write to the CD (VC++ 6.0). We are now running on Windows XP and the shell commands no longer appear to work for XP. Is there any simple way to write to the CD from our application without using a 3rd party product?
Thanks! rwaca

i get the handle of a textbox in an opened window using the function
EnumChildWindows(,,)..
after i obtained the handle of this textbox i want to set a specific
string in this textbox.
"HINT" : the function SetWindowText(,) isn't a valid to this task(why?)
more--->
the opened window has a textbox ,a button ,a label;
and when i used the spy++ program of Microsoft tools to get the caption
to each of them after using SetWindowtext(,),i observed that:
the caption of the label is same as the value appears on it<the
caption="" and="" value="" appears="" are="" equal="" to="" each="" other="" the="" string
posted="" by="" setwindowtext()=""> ,BUT
the caption of the textbox isn't the same as the value appears on it
<the value="" is="" nothing="" but="" the="" caption="" equal="" to="" string="" posted="" by=""
setwindowtext()="" function="">then i want an API function to set the value of the textbox not the
caption..
thank you very much for any help..

SetWindowText() should work if it's a standard CEdit control (which happens to be derived from CWnd). It's possible that the control is handling the WM_SETTEXT message in a custom manner.

I have a dialog box with a numeric edit control, and I would like to know how to get the control to allow the '-' character so you can input negative numbers as well as positive ones.
Can anyone help,
