I suspect the mask will be fastest. If you make the mask a DIBSection it will be fastest of all, you'll have access to the underlying bits without having to call GetPixel in a DC.

When you're in the leftmost pane of the Visual C++ IDE, with the ClassWizard, FileView, ResourceView... is there a keyboard shortcut to switch between the three? I'm really big on keyboardability but have never found a way to switch between these tabs without wasting my time grabbing the mouse.
Thanks.

Hey Guys
I was wondering if someone could tell me the function that allows you to browse through the available drives and folders on yourcomputer and select which one to use.
Cheers

Merry Christmas Everyone ![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)
I hope someone can help me. I was wondering if there is an easy way to draw a line where the pixels alternate colour, I want to draw a grid over a bitmap the same way that the resource editor does, with alternating dark and light gray pixels. If I create a pen with the PS_DOT style, the dots and spaces are 4 pixels in length, and that looks like crap. Right now I am using the SetROP2() function with the R2_NOT flag. It looks good if the bitmap has light colours, but not if the bitmap has dark colours. I guess I could draw the lines one pixel at a time, but I am hoping there is an easier way. If any one knows, I would appreciate hearing from you. Thanks.

You can create a pattern brush and then use that one pixel wide to generate a line.

Hi.
Conventionally speaking, do you declare and initialize variables at the beginning of a function or loop or right before usage.
For example:
int main()
{
char temp;
cin >> temp;
cout << "1234... & " << temp;
cin >> temp;
cout << temp;
int x;
cin >> x;
cout << temp << " & " << x;
return 0;
}
The arbitrary code above depicts declaration of variables right before usage (int x).
Which way is most convention is arguably better?
Thanks,
Kuphryn

Thanks!
As of today, I have begun to declare variable when:
1) there is something to initialize it with
int x = ...functure return, something added/subtract, etc, to other variables
2) right before its usage
int x = 3;
cout << x;
The only time I declare a variable at the top:
int x = 0;
is when it will be referenced to.
function(int &aboveX)
cout << aboveX;
So aboveX is a reference to x.
I began learning and practicing C++ about four months ago. I find something really interesting. I find that when you first learn C++ in college and reading beginner C++ books, the professor and author typically recommend declaring variables right at the top. They make it like it is imperative that we do that or the program may not work. Now, I feel that the programmer is in control of the program and that he/she can declare variables wherever is appropriate. As I mentioned, I feel it is much easier to recognize variable when the program declare them accord to the examples above.

He folks!
I created a dialog based application and made it to a service. Not a big deal.
The service has a icon in the system tray.
If you click on the item, the dialog window pops up, so that the user can see some information about the current status of the service.
In that dialog window, i created a property sheet with two property pages in it. As fare i do NOT create that property stuff, everything works fine, but with the property stuff AND when the user loggs out, i always got a runtime error!!!!
WHY???
By the way, when i just start the service and then terminate it again, by the windows nt control manager, everything goes well, also!!??
Thanx in advance

He!
It's me again!
So far i found out, that the problem is neither placed in the property sheet
nor in the property pages BUT in the CListCtl, which is placed in one of my
property pages!!!!
When i take the CListCtrl out of my page, everything works fine.
So does anyone know what i shall do with that list control???
Greetings
Normen

Hello All,
Is it possible to do network programming with Standard C++ only and nothing else. I know you can do it with MFC, but is it possible with only Standard C++?
See, Java has built in networking capablities without using any third party libraries.

You can use Winsock or regular sockets.

Hello, the codegurus around the world.;)
When you use the standard C++ code with socket,
the code depends on OS library.
1) Windows -> WinSock or WinInet (FTP, HTTP)
2) Linux and Unix -> Berkley socket library.
3) Mac maybe has some library.
So, I don't think that we can write the socket code compatible with all OS
by C++.
Please, don't send me your email about your questions directly.
Have a nice day!
