Hello,
When you define in some function a critical section you define a critical section block or variable ?
I will explain - when some thread get to this Critical section and the Critical section is lock - so this thread will go sleep until this Critical section will be unlock and the event will be called to rise up.
But my problem (or my bad understanding) is about the block of the critical section - i think that the critical section is only to block thread and make the thread sleep and have no direct connection to the block - but some other thought is that the critical section is define only on block.
Can someone explain the main idea of the critical section in this case ?
Thanks on any help.

Why? What part did you not understand?

Maybe not directly, but you can easily infer the answer.

A critical section is a block of code (that can contain variables).

I'm not sure I follow..
A CRITICAL_SECTION variable is an opaque object which holds a lock state. It's not a handle to anything, like mutexes are (they are kernel objects). I'm not sure what you mean by block, but I'm going to assume it's a body of code such as { ... } . A critical section is not automatically associated with such a block. The state of the critical section object is determined by the Enter/Leave functions, and can span over any number of blocks.

A critical section is a small section of code that requires exclusive access to some shared resource before the code can execute. To protect that section of code we need to encapsulate that code in EnterCriticalSection and LeaveCriticalSection function call.
Better avoid using 'block' terminology.

In MFC-speak that would be a CCriticalSection object along with a CSingleLock object.

Does anyone know of a way to take an existing VC project and clone it to another directory with a new name. The project file would be re-named, along with the cpp files.
Captain, I must protest, I am NOT a merry man.

Did menually before, by renaming source files and modifying these project files:
.dsw
.dsp
.rc
These files can be opened and changed in any text editor.
- It's easier to make than to correct a mistake.

vc provides one method.
build new project, select "Custom AppWizard",input new project name.ok
show "Custom AppWizard - Step 1 of 2", select "an existing Project",
next, show "Custom AppWizard - Step 2 of 2",
now notice select yourself project (*.dsp),finish.
build...
now it will bring "*.awx" and "*.pdb". then copy they to
vc install directory common\msdev98\template.
now you build new project, use "AppWizard", you find new item.

Terms:
Ext: Computer which to which I can connect using telnet.
Local: My personal computer.
MyApp: Application which runs on Local.
Problem:
I would like to control an application on Ext. using MyApp running on Local. One way I can think of doing this is to open a command console, CC1 on Local, and telnet into Ext. If I then redirect the input/output from MyApp (running in a second command console, CC2) to CC1, I can accomplish this task. The windows utilities GetStdHandle and WriteConsole look like they could be useful here. I am familiar with C but new to windows programming,
so I don't know if this strategy is a good approach, or perhaps there may be a much better way to accomplish this task (TCPIP server?)
Any suggestions would be appreciated.
Thanks.

Have you considered Remote Procedure Call (RPC)? There's also Remote Execute (REXEC).

I did not consider RPC, and think this might be a good solution. Am studying this.

Good to hear people still use RPC (which is much simpler than COM!)

Have you tried Rent-A-Coder? That site handles work-for-hire, and might even help out with homework.

Ok, you want C++ this time?
void main()
{
Cout << "I'm trying to cheat on my homework, but am too stupid to avoid being caught.";

i am currently trying to make my program copy or move itself into my "programs to test " folder, by itself. I have been fooling around with trying ot use the shellexecute to move it but have found it easiest to use a Code to do it. My MAIN problem is that in order to make the program move itself, i need it'd current file path (i.e. c:\\Documents and Settings\\Droz\\My Documents\\Program.exe)
I have been trying to use GetFilePath, GetSystemDirectory and GetFullFilePath and still have not been able to make it work.
Breaking it down, i need the program to be able to know and be able to print out to the user its current location.
Thank you for any help. Happy programing.

This is the closest form i could find. i am sure it will be very similar
Would love any suggestions on the coding;P
