Have you ever wanted to push a variable onto a form without using atag? Property functions let you create custom properties for forms or classmodels. Use PropertySet, PropertyGet, and PropertyLet statements to manipulatecustom properties. For example, you want to send a key value to a form so that the keyis there in time for an SQL query to use it in a condition. Include a variabledeclaration for the property as a form-level variable:

 Private msKey as String

Then add two procedures for PropertySet and PropertyLet for the form:

 Public Property Let GetKey(vNewValue)	msKey = vNewValueEnd PropertyPublic Property Get GetKey()	GetKey = msKeyEnd Property

You can now set the property from elsewhere by using:

 Form1.GetKey = "David"

In your form, use the variable you declared for any usage in your code.Property Procedures can be a bit more complex. But, the point is that theVB4 has become much more adaptable to your needs. Customize it to fit.
