Question

I\'m trying to get a notification to pop up something like these bubbles in an MFC application:

Answer 1

You could just use System.Windows.Forms.ToolTip.

using System.Windows.Forms;

...

ToolTip myTip = new ToolTip; // create tooltip
myTip.IsBaloon = true; // give it a round shape
myTip.SetToolTip( myTool, "You're hovering above myTool." ); // register popup message for 'myTool'
...
myTip.Show(myTool, "Forced modal pop-up.", 1000 ); // display pop up message for 1 sec at 'myTool'
