Why don't you use ICMP (Internet Control Message Protocol ) for checking remote host connectivity?!
Reading the output of another process is awkward for that purpose.

You can use socket, as well.

You can download ping implementation from

Goodluck,

how to set the file association for extention

Hi all,
I used FindExecute() to check whether the user given filename ( eg. c:\abc.ttp ) has an associated file/application (.exe file) to open/print with.

How can I set or tell the OS system to open/print this extention ( eg- .ttp ) to open/print with this associate application ( eg- notepad.exe )??

Like setting register key in register table.. but I want to done in programmatically.
I was trying RegOpenKey, RegCloseKey, RegCreateKey but dont really know how to use them.

Can someone kind enough to give me sample code of how to use those functions please if they are the right functions to use for setting associate files for given file extention?

thanks

thanks but that wasn't what i wanted.
I found the way to set the associate file without showing openwith window.
ways to do it is I used system command,"ASSOC", to set the associate file for particular file.

I just started trying to use Doc/View to create an application. My MFC book has an example that doesn't really have any practical applications. I want to create a text editor, and have created good ones with Win32, but I don't understand how to do it in MFC. Where do I put the code in for the Edit Field?

The easiest way is to use a CEditView as your view class. You can also use a CFormView and base your view class on a dialog template which would contain an edit control.

Hidden Processes

How can I hide a Windows Process from Windows Task List. This means that process should not appear in task bar, systems tray or in Task Manager Process's List, even Task Manager Process Count or Threads Count should not show a new Process or Threads running. How can I do this?? Another opposite problem is that, How can I find such Processes/Threads running on my System??? Please any experts do reply and keep the solution very simple.

The only way to hide a process from the task manager is to... exit the process!
In other words: No way

Being able to do so would be a security compromise. I don't think it is possible

I dont know if it is possible to hide from task manager of NT/XP, but it is certainly possible to make the app hidden when you use CTRL+ALT+DEL in 9x/ME.
I am also looking for such code. I've seen some apps doing this.

I think it is possible by making a service of your application.
MSDN can provide you with the details of how to make a service of your application.

Don't think you are, know you are...

The process view applet which is part of the Visual Studio install (optional in VS7, optional but installs by default in VS6, I think.)

Thanks,
The problem I'm actually having is that I don't know how to reference the listbox that I have created with the dialog editor.

For example:

CListBox* myList;

myList->AddString( str );

Do you know What code I need to use so that myList refers to the listbox that I have created in ID_MYDIALOG? Does this make sense?

Thanks in advance

Thanks Dave,
For some reason I can't add any member variables, the "variables" menu item is grayed out when I right click on a control in the dialog editor! It's ok coz I found an easier way of doing it using:

SendDlgItemMessage(hDlg, ID_MYLIST, LB_ADDSTRING, 0, (LPARAM)"Hi there!");

Thanks for the help,
Paddy.

in FindExecutable(fname,path,result) what is "result" set to?

I would suggest in your declaration should set
LPTSTR result = NULL;

then you would easily see what is going on

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
