If the program is service, you can find with IsServiceRunning API.
If it is Window/Dialog Exe, you can do it with FindWindowEx API. Read how to use FindWindowEx API.

Be careful when using FindWindowEx(). It has the potential to cause a deadlock situation.

I have to create a class which parse a char

This class must contain a function which return the position when it was made a change of bytes. For example if in char I have 0 0 0 1 0, the function must to return 4. If I have 0 0 0 0 0 0 1 1 1 1, the function must to return 6. Bytes are loaded from a file.txt. I want a solution, if it possible in next 2 days.

Thanks,

How would you do this on paper?

1) Read the first byte, and store it in a variable.
2) Read next byte.
3) If it matches the first byte, increment counter. Go to 2.
4) If it doesn't match the first byte, stop.

I'm curious why

0 0 0 1 0

should return 4, but

0 0 0 0 0 0 1 1 1 1

should return 6...

Good luck with that Smile | :)

How do I create a virtual serial port?

How do I create a virtual serial port (e.g. COM9)?

Is building a kernel mode device driver the only way or can I create something in user mode that my applications can open and interact with as if it was a standard serial port?

Thanks
Alec

I want to display a dialog in a MDI application whenever there are no more documents(or dialogs) open.
Is there a message that i can intercept when everything is closed?

You can enumerate the number of child frames open at any give time by using EnumChildWindows. In your particular case, you can check on close of child window (the message is WM_CLOSE) that how many windows are open. If they are 0, u can show the dialog.

It's already been done here[^]

You would be having the id of the control when creating it. Use GetDlgItemText.
virtual BOOL Create(
DWORD dwStyle,
const RECT& rect,
CWnd* pParentWnd,
UINT nID
);

Somethings seem HARD to do, until we know how to do them.

Either this article
http://www.codeproject.com/listctrl/listctrldemo.asp[^]
or this one

http://www.codeproject.com/listctrl/xlistctrl.asp[^]
might help you.

And for the dynamic editbox, you specified an ID for that when created. use that ID and

GetDlgItem(ID)->GetWindowText();
