Setting Properties At Run-Time

By now you know how to set a componentproperty before running your program (=at "Design Time"),Now we will learn how to do that during program's Run-Time.

To change a property, use the following syntax:
TheControlName.ThePropertyName = TheNewPropertyValue

For example, suppose we have Command Button With the name "Command1", and we want toset its Caption property to be "Hello".To do that, we will use the following code:
Command1.Caption = "Hello"

To test it, simply copy the line above to yourCommand1 Click event, run the program and click the button at run-time.

Note that the Hello is inside quotes becauseit's a String.You can assign a variable value to a property:
Dim MyVar As String
MyVar = "Hello"
Command1.Caption = MyVar

This code will do exactly the same as the code line above it.Note that MyVar is without quotes, because it's variable.
And how do you set a Form caption property at run-time?
exactly the same:

Form1.Caption = "Hello"
