hi, I used the following code to GRAY the "Mute all" check box,but it is not working.Is there any other method. HWND hwnd1=::FindWindow(NULL,"Volume Control"); HWND hwnd=::GetDlgItem(hwnd1,0x3e8); ::EnableWindow(hwnd,FALSE);

Your code snippet worked fine for me.

No. What you have will work.

hi, I am using Windows XP machine.Which system are you using.May be it does not work on XP system.

hi, It worked for me also ,but it works only when the "Volume Control" window is opened and then you execute the code snippet.What should happen is that even when the "Volume Control" window is closed and then you excute the code snippet,it should work.

Of course. What else would you expect? The Mute all checkbox does not exist otherwise.

Lots of luck to you. It's impossible to manipulate a window/control that does not exist.

hi, ok then is there a way to GRAY the volume control icon in the task bar.

[David Crow]

Why would you even consider doing this? Do you not think that the user would be somewhat annoyed that they could not change the volume on their computer? How friendly would that be?

Just because it is a requirement does not make it a good idea. Please explain what you are doing and maybe we could could come up with an alternative solution that is more practical.

I just made eight posts to this thread. Don't you think I would have helped if I could? Do you think that I am purposely withholding information?

hi, In our project there is an option to Control the Volume of audio of the system,so when the user does control the volume through our software,he should not be allowed to go and change the volume through the system.
