I want to implement "whats this" functionality as seen in most of windows programs. For example -> When you

right click on desktop and select properties and when u again right click on the properties dialog you get a

pop up menu with "whats this". When i click on that u get a timy description of that part of the dialog. How do

i do that. Can you give me an example program. How do you implement "whats this" in a win32 program using

windows api. Is there any example program on the net with source code using which i can learn to implement it

in my program.

Hello hemanth.balaji

The whats this stuff available in Windows is nothing but the ToolTip that is displayed and after certain time it expires.

Use the tagTOOLINFO struct to fill in the necessary details and use SendMessage function to display the ToolTip at a particular location.
