Hi,
The problem is I did it in a function, so the object(control) is out of
the scope. Here is the case:
In my form load event, I call a function to load all controls
programmingly, then in other function, I want to use these controls. For example,
private sub Form_Load(...)
...
LoadControl
end sub
private sub LoadControl
dim aButton as new button
aButton.name="MyButton"
aButton.text="OK"
'add other properties here
me.Controls.Add(aButton)
...
end sub
private sub MyFunction
...
'todo: need set Backcolor=blue to the button with name of "MyButton"
end sub
How can I get the proper button handler?
thanks
william
The simplest approach is to declare your control variables at the form
scope, not the LoadControl scope. You can then access the variables from any
method in the form class.
Your only other approach is to loop through the controls in the form's
controls collection, looking for the control that matches the criteria you
want to match, then setting the BackColor of that control. This is a very
bad option, though, since you would be looping through every time you wanted
to change a property of a control. Better to just declare the variables at
the form's scope.
