 Sarcasm is the lowest form of wit...but the highest form of intelligence . Sorry for the sarcastic tone, just having a giggle. Anyway, I had a look in MSDN and found the Win32_StartupCommand class which may be of some use, though MSDN is very unclear about what it does and how it works. There are a whole host of other things relating to Win32_LoadOrder_blah which may be of some help, I think its a way of accessing services but I am not sure, you may have to look these things up on-line at msdn to get some examples cos there aint any with MSDN 6.0  I may be barking up the wrong tree, but its something you can look at that may be of some help, I hope. Good luck, if I find anything else, or you does, or anybody else does, post it up!

Hello,
Look to the www.logicsoftware.net portfolio
and find there ATL Button. This is my old project.
Ask my friend for more details about it via "contact us".

Hello everyone. I am writing a program which is going to create a new folder inside the current user's My Document folder. How do I find the path to the current user's My Document folder? ie. "c:\my documents" on Win98 or "C:\Documents and Settings\SomeUserName\My Documents" in win2000? And what should my application default to when it goes to create datafiles if run on Win95, since there is no "My Documents" folder in Win95? Default to the application's path? I was told by other developers that an application should default to the My Documents folder when creating a new datafile for the first time (like Word does).

Does anyone know where i can get my hands on a good winsock tutorial? I've read a few so far, but I'm looking for something that gives me a list of functions and explains them to me really. I am trying to write a basic client/server application that will be used in conjunction with a game, so I'd like it to be UDP based please. Thanks in advance for any help!

I have seen some good ones on this site in the past, especially for TCP. Browse around.
Maybe some specific questions will do.
Good luck

Hello, I am trying to improve the speed of a function which heavily using these functions.
template<class T><br />
T min(const valarray<T>& x);
and
INT abs( int n ); in math.h
and
int memcmp( const void *buf1, const void *buf2, size_t count );
Any better functions to be used other than these.
Thank you.

Try using memmove instead of memcpy.
As for abs(), try replacing it with this inline function:
inline int myAbs(int n) {
if (n < 0)
return -n;
else
return n;
}
That would be a lot quicker than a function call. There maybe more to the abs function than that, but I don't know the details.
As for min(), I've never seen that particular version of it before. If you are doing something thats computationally heavy on prepared data, you could sort the data ahead of time and then just pull out the first element, that'd be your min.

<br />
void *p = 0;<br />
DWORD allocadd = 0x500000;<br />
<br />
p = VirtualAlloc((void *)allocadd, 0x1000, MEM_COMMIT , PAGE_READWRITE);<br />
<br />
if (p == 0)<br />
{<br />
DWORD err = GetLastError();<br />
}<br />
This code works fine under Windows XP, but on 2K I get an "ERROR_INVALID_ADDRESS" error. The memory page in question is free, I checked, but I can't allocate it! If I change the desired address to something like 0x502000, it will work. But I need to be able to choose the base address.
Please help!

Hi,
The following example demonstrates how to commit a specific page of reserved addresses from the previous example to a page of memory.
/* Commit memory for 3rd page of addresses. */
lpPage3 = VirtualAlloc (lpBase + (2 * 4096),
4096,
MEM_COMMIT,
PAGE_READWRITE);
Notice that instead of specifying NULL for lpAddress, a specific address is given to indicate exactly which page of reserved addresses becomes committed to memory. Also, this page of memory is initially given PAGE_READWRITE protection instead of PAGE_NOACCESS as in the previous example. The return address from the function is the virtual address of the first pages of
committed addresses.

Hi all, I'm a Visual C++ newbie and I've never really built a GUI app before. Every example I see seems huge with all the menus/windows/etc.
I was wondering how best to organize an application. Would it be ok to create one project for the MDI part of an app and another project for the menu part?
I tried searching for tutorials on this but didn't come up with much. Any help would be greatly appreciated!
Thanks!!

That does not make too much sense. A complete Doc-View application in MFC has only about a handfull of classes (APP, Doc, Frame, View and a few others). To this comes your application logic. You quickly learn what to find where.
Additionally, MFC tries quite hard not to make a difference between a user clicking a button on the screen, selecting a menu entry and typing an accelerator.
You wont do any good by trying to separate these parts.
Who is 'General Failure'? And why is he reading my harddisk?!?

The MFC App wizard will generate you a framework MDI application. This is probably the best place for you to start.

Normally you create multiple projects for a couple of reasons, 1) create libraries or dlls for code reusability 2) separate base class code from higher level derived code and 3) for multi-component based projects such as a database and web app where you want one project to define the database and another to define the web functionality, before linking them together, perhaps via another project. Since a menu is a part of the GUI for the app, it should be defined in the same project, unless you are going to use the exact same menu in all your applications (doubt it) or are creating a generic menu class (which is doubtful since you are a beginner ). If your using MFC, I would create an MDI app from the wizard and using the resource editor (greeny tab on the project view pane) create your menu items in there and read up on MSDN how to handle them when they are clicked, its quite easy really, once you've had a play I'm sure it will all make sense .

Hi,
I can suggest to buy LARGE HDD to download all Internet
to your local computer.
This is Joke, I hope you understand it.
Real solution is in the saving state of your
download. After restoring connection you can
start it from the breakpoint.

Are you using MDI or SDI? If so, check out document-view articles.
Are you using CHTMLView?

I have this simple question about casting... take a look at the code snippet below:
Base * pBase;
Derived * pDerived;
pBase=new Base(1);
//DOWNCAST:
pDerived = dynamic_cast<derived*> (pBase); //Why did it NOT failed? Sure dynamic_cast supports "down-cast" but pBase is pointing to a "IN-complete" object.
//pDerived = (Derived*) pBase; //What's the difference between this sort of simple casting and dynamic_cast? I know that with simple casting, you can't down-cast. Does it mean that with up-cast, simple casting is just as good as dynamic_cast? I have a feeling that dynamic_cast will check at runtime if the object is complete/incomplete (simple casting don't do this) - and is thus safe. Is this the reason why we use dynamic_cast?
pDerived->m_nAge = 10; //Of course, this will crash.
Also, here's C4303 from MSDN:
"C-style cast from 'type1' to 'type2' is deprecated, use static_cast, __try_cast or dynamic_cast... C-style type casting or function-style casting is NOT SUPPORTED when using Managed Extensions for C++...."
>> I don't think it's NOT SUPPORTED - why the documentation states that it's not supported? I just did it in a C++ managed console application and it's just a warning - not error.
Thanks.
