Hi All,
I m fighting against a problem that drove me crazy for long hours, I wanna create a simple prog like Client/Server under linux using C code. I wrote a Server.c and Client.c Files but when i type
$gcc -c Server.c Client.c
$gcc -o Blood *.o
it told me that there is a double declarion of the function main. (i'm using linux)
So could some one tell me how could i test my prog on the same mchine ??? (local) Thank you !!!!
i Need Help so plz !!!

No wonder: While you should build two applications with the Client.c and Server.c, you are actually issuing the commands to build just one app with those files.
BTW there's a Linux forum on CodeProject.

If you want to build just one application using two (or more) source files, then there should be one (and only one) function main.

What about 'man gcc'?
Probably you have to build 2 apps, for instance
gcc -o cliet client.c any_shared_obj.o
gcc -o server server.c any_shared_obj.o

*.o it's only a wildcard way to say 'link with all object files you find'. You get the error because the compiler finds both client.o and server.o (and both have a main function inside). I strongly suggest you to issue the man gcc command.

If you want to run two different processes, then you should build two different programs. Yes, it's possible to start two different processes from a single program in Linux using fork(), but that appears to be way beyond your current skill level.

Hey there, ive got a feeling there wont be an easy answer / solution to this question but if you dont ask you dont get!
I was wondering if there is any way to globally capture mouse overs in windows. Iam not sure if the way ive described this will make much sense to anyone so a quick usecase might help. When a user opens up the start menu and highlights 'my documents', the background colour changes to blue to show you have your mouse hovered over it. Can this event possibly be captured? I imagine capturing mouse overs on the start menu will be different to say catching a highlighted menu option in visual studio. But id really like to know if there is any way of globally detecting when hovering the mouse "highlights" something on the screen in relation.
Any help guys?
Thanks in advance

Have you thought about getting into the address space of the process that creates the window(s) and subclassing the particular window in order to capture the relevant messages?

I had looked into this and it doesnt seem to hard to do providing I learn enough about the win32 API. However the part which seems to vary between applications is capturing the relevant messages. Ive used winspector to look at messages being sent back & forth between windows and there does appear to be any pattern to what happens when something under the cursor changes due to a 'mouse over'. I noticed the startbar (dv3controlhost , syslistview32) calls wm_ncpaint followed by wm_erasebackground when I move between items and the mouse overs activate but this doesnt seem consistance with other applications ive looked at like Adobe Audition. But ive notice Adobde Audition uses alot of custom classes in its contruction......

Hello.
Can someone explain me how to create a C program using Visual Studio 2005?
(I've been trying lots of ways, e.g. creating c++ files, and changing
extension to a c file, but I was getting errors).
Thanks!

Write your program in VC++ seeing as it's an extension to the C language and just write your C code. You can ignore the C++ additions such as object-orientation etc
(or go with Mike's suggestion.)
[Edit]
If you're looking for a good C compiler, I'd recommend Pelles C. It's free, too.

New Visual Studio 2005 projects default to 'compile code as C++'. To change this, go to the project's Property Pages dialog and click the C/C++ folder, Advanced, and change Compile As to 'Compile Code As C (/TC)'.

There's no default way to do that (as far as I know). You'll have to handle that yourself...

I'm trying to verify that a path exists by using either PathFileExists() or GetFileAttributes(), but when a network path like \\SWAP01\slave02\mydirectory doesn't exist because the system isn't on, both functions hang.
In fact, they hang pretty seriously, so much so that I can't kill the process from the debugger OR the task manager. My only option appears to be to log off from the system and log back in.
Any thoughts on how I might better deal with this hang?
