Convert String To Object Or Function

I do not know if this is possible in VBA, but I am hoping it is as it will make my life much easier.

Is it possible to say have a TextBox and a CommandButton, that does the following?


Public Sub Execute()

Dim ObjectName As String
Dim Object As Object

ObjectName = txtObject.Text
Set Object = ObjectName

Object.Execute

End Sub

Or to take it a step further:


Public Sub Execute()

Dim ObjectName As String
Dim FunctionName As String
Dim Object As Object

ObjectName = txtObject.Text
FunctionName = txtFunction.Text
Set Object = ObjectName

Object.FunctionName

End Sub

Are there any inbuilt functions that will create/reference an object based on a string containing the name of the object or function?
