ei masters... how to use the whatsthishelp?! in the property....
To use "what is this?" help in property tag, you must have your own help-file (helpFile.HLP) and link it to project by set App.HelpFile = App.Path & "\helpFile.HLP"
When you create your-own help file, you have choice to select helpID (a number in Long-Integer) for each content. As soon as you link the help file to your project, set WhatsThisHelpID = helpID (was created in helpfile).
Easiest way to make a help file is using "Help WorkShop" (a untility from Visual Studio). If you install a full version of Microsoft Visual Studio, you will see Help WorkShop from StartMenu/Microsoft Visual Studio/Visual Studio Tools/Help WorkShop.
