Mixing
Taskbar notification glow
I have a TCP Chat application. When a new message arrives, I want to make the taskbar glow until the user opens the form again (in case it wasn't focus/activated).
An example of what I mean:
http://puu.sh/4z01n.png
How can I make it glow like that?
Thanks!
If you still don't understand what I mean.. The image I provided is what appears ON the icon i nthe taskbar when something "glows". Meaning there is a notifcation. That's what I want to acheive.

You need some interoperability to achieve this,first of all add System.Runtime.InteropServices namespace to your class,the in you class define this function at the beginning,
[DllImport("user32.dll")]
static extern bool FlashWindow(IntPtr hwnd, bool FlashStatus);
It is an API function and it's description says, The FlashWindow function flashes the specified window once..Then add a Timer to your class(drag-drop it from the toolbox,set its interval to 500 Milliseconds).Then assuming Form1 is the window you want to flash,use the following code to achieve this;
private void Form1_Activated(object sender, EventArgs e)
{
timer1.Stop();//Stop the timer to stop flashing.
}
private void Form1_Deactivate(object sender, EventArgs e)
{
timer1.Start();//Start timer if window loses focus.
}
private void timer1_Tick(object sender, EventArgs e)
{
FlashWindow(this.Handle, true);//Flash the window untill it gets focused.
}
Well,call timer1.Start(); when a new message arrives.A sample just in case if you need.
Hope this helps you.

For some reason, it's still flashing evne though I am focusing the window. Do I have to set the Focused proeprty or something?..

You can use an extension method that will Flash the window until it receives focus, without using a timer.
Just call
form.FlashNotification();
public static class ExtensionMethods
{
[DllImport("user32.dll", CallingConvention = CallingConvention.StdCall)]
[return: MarshalAs(UnmanagedType.Bool)]
private static extern bool FlashWindowEx(ref FLASHWINFO pwfi);
private const uint FLASHW_ALL = 3;
private const uint FLASHW_TIMERNOFG = 12;
[StructLayout(LayoutKind.Sequential)]
private struct FLASHWINFO
{
public uint cbSize;
public IntPtr hwnd;
public uint dwFlags;
public uint uCount;
public uint dwTimeout;
}
public static bool FlashNotification(this Form form)
{
IntPtr hWnd = form.Handle;
FLASHWINFO fInfo = new FLASHWINFO();
fInfo.cbSize = Convert.ToUInt32(Marshal.SizeOf(fInfo));
fInfo.hwnd = hWnd;
fInfo.dwFlags = FLASHW_ALL | FLASHW_TIMERNOFG;
fInfo.uCount = uint.MaxValue;
fInfo.dwTimeout = 0;
return FlashWindowEx(ref fInfo);
}
}
}

You can use an extension method that will Flash the window until it receives focus, without using a timer.
Just call
form.FlashNotification();
public static class ExtensionMethods
{
[DllImport("user32.dll", CallingConvention = CallingConvention.StdCall)]
[return: MarshalAs(UnmanagedType.Bool)]
private static extern bool FlashWindowEx(ref FLASHWINFO pwfi);
private const uint FLASHW_ALL = 3;
private const uint FLASHW_TIMERNOFG = 12;
[StructLayout(LayoutKind.Sequential)]
private struct FLASHWINFO
{
public uint cbSize;
public IntPtr hwnd;
public uint dwFlags;
public uint uCount;
public uint dwTimeout;
}
public static bool FlashNotification(this Form form)
{
IntPtr hWnd = form.Handle;
FLASHWINFO fInfo = new FLASHWINFO();
fInfo.cbSize = Convert.ToUInt32(Marshal.SizeOf(fInfo));
fInfo.hwnd = hWnd;
fInfo.dwFlags = FLASHW_ALL | FLASHW_TIMERNOFG;
fInfo.uCount = uint.MaxValue;
fInfo.dwTimeout = 0;
return FlashWindowEx(ref fInfo);
}
}
}
