Mark,

How about changing form's caption in Resize event. If form minimized, use one caption, if restored, restore your original caption.

>>Mark their is a show tips in the forms property list that if you set it to true, you can then select the txtbox or the lable and in its property list there is a property for tool tip text. You can put what ever you want there.

>I am aware of all that. But there is no ToolTipText property in a form. I would like to provide more info in a Top Level Form tooltip than what the caption provides. I am doing some very lengthy processing, so I minimize the app and show a percentage complete in the caption so this shows in the Windows Taskbar. I have minimal area to display a status when the app is minimized to the Taskbar. I would like to stuff more progress/status info into the tooltip so when you hover over the app button on the taskbar, the user can see progress. Much like a tooltip on an item in the system tray.
