How can I display a ToolTip arbitrarily whenever a control recieves focus i. e. whenever a control receives focus irrespective of from keyboard or mouse the tooltip should automatically pop up.
Also can I use ToolTip to display informational messages, say for input errors when a user is entering data into a control. For example, if a TextBox is supposed to accept numeric data only, then if the user tries to enter Aphabetic data into it then the message should be displayed in ToolTip rather than MsgBox.
A kind of Baloon Help to be precise.
This is to be done through VB only, API can be used.
