In my project, I need to automate the process of creating a new "incoming" network connection which acts as a server for client connections. We can manually go through this process: "Control Panel" -> "Network Connection" -> "create a new connection" -> Click "next" on the "new connection wizard" dialog -> Choose "set up an advanced connection" -> "connect to another computer" -> choose "Host" ... We can assume that user always select the fixed choice at each step.
Is there scripting tools or Windows API which can automate the above process? Anyboby can give me some hints? Thanks a lot,
-Jeff

I am sure that all the wizard does is set up registry entries. The trick is to figure out which entries, and set them yourself.
I am sorry, but I do not know what the entries are.

Hi,
i need to find out the amount of processor time used by a process.
My Requirement:
i am running 2 programs.
1) The ACTUAL process.
2) a monitor process.
The ACTUAL process goes into an infinite while
loop. it begins to use a 99% of the CPU time.
i need to detect this condition from the monitor
program and kill the ACTUAL program.
please help, its very urgent.
thank you..

Just to add my 2 cents, this sounds like a very BAD solution. You need to figure out what is causing the infinite loop in the first place, and fix it! Doing it your way could cause other problems - resource leaks, for instance, or leave files/data in an unknown state.
An expert is somebody who learns more and more about less and less, until he knows absolutely everything about nothing.

dear navin,
i gave an example....
suppose... a program enters into an infinite
loop... (suppose)...
then, it would surely use the maximum CPU time.
there's is a method by which we can detect the
cpu usage time of a process. i've seen the
method somewhere, but i dont remember it now..
can you help me.... ??
bye

Using the majority of the CPU (e.g., 95%) and an infinite loop are not necessarily the same thing. While an infinite loop does cause the CPU usage to go very high, other operations can also cause the CPU usage to spike. So, if you were simply terminating a process based solely on CPU usage, you may be doing so for the wrong reason. Make sense?

I agree with Navin. Address the infinite loop issue and the need for a separate "monitor" process should go away. Even if you do need an infinite loop (e.g., while (1)), you should still take measures so that it does not consume all of the CPU.

I agree with other two statements.
you want to do an ugly thing 
but look for a class from Paul Maker on CP

I think this can solve your problem.

Hi,
I have dialog based application. If my event handler is in any class other than the main dialog class it never gets called. I would like to move the event handler to my subclass of a control.
Suggestions? What am I doing wrong?
Thanks

some example code so that we can see what happen? I'm not a wizard

Example code probably won't help but I can walk through the steps to reproduce the problem.
I'm using Visual Studio 2003 .Net
- Create new MFC Application, select application type Dialog based.
- In the class view, using the wizard create a new class with a base class of CButton, I called mine MyButton.
- in the main dialog create a new button, right click and "Add Event Handler" choose the Message type: BN_CLICKED and the class as MyButton.
- in the handler OnBnClickedButton1 add MessageBox("hello");
- run application
- click button, nothing happens
however if you added the Event Handler to the main dialog class created by the wizard, then everything works fine. 
Ideas?
Thanks
Hua-Ying

did you put a break point in your handler ?
me think it's the MessageBox that simply doesn't show.

Hmm. I'd say the button press must be notified to the parent of the button, in this case the dialog.
Notice that the event is called "BN_CLICKED". the "N" in "BN_" usually means "notification", in which case, the button's parent is notified.

Use message reflection. See technical note 62 in MSDN. Search for TN062

In the message map for MyButton, add the following:
ON_CONTROL_REFLECT(BN_CLICKED, OnBnClickedButton1) and remove the ON_BN_CLICKED() statement.

What class did you derive from? What event are you wanting to handle?

See my response to Jamie please, that should be enough to completely reproduce the problem.

IIRC, I think you will need to use "reflection" to make this work. There is usualy a weird message handle for classes like button that allows them to trap their own click messages.
In VS 7, and I think VS 6 did it this way too, the message you want to trap in the wizards looks something like:
=BN_CLICKED
And the message map entry will be something like:
ON_CONTROL_REFLECT(BN_CLICKED, OnBnClicked)
Hope this helps.

Thanks for everyone's help!!
For anyone else who's having the same problem, one last thing you must do before this solution will work is to add a variable in you main dialog class so that when it loads your control it will use the subclass for the control instead of the original.
Details: using the class wizard generate a new variable with your subclass type, click the control check box (VS 2003 .Net) so that DDX_Control will update the value.
You can also follow Chris Maunder's great tutorial on subclassing controls:

Straight from MSDN:
WCHAR wszUserName[256];
char *sString = "XYZ";
MultiByteToWideChar(CP_ACP,
0,
sString,
strlen(sString) + 1,
wszUserName,
sizeof(wszUserName) / sizeof(wszUserName[0]));

Hi,
I have several SplitterWnd with dialogbox-based FormView in my application. For a good layout i need the size in pixel of the dialogboxes (generated with the ressourceeditor) as early as possible to arrange the splitter windows.
Please help me!
