How to read the names of package variables in custom task

Hi there,
I found a lot posts about package variables. But nothing about how getting access to the
names of the package variables programatically.
Why? - Well I want to create a list of variable names from which the user can choose
one of in a UI of a custom task. That's all... :)
I thought of using the variable dispenser in the Initialize method of the task and then storing the variable names into a property which can be read by the UI through the taskhost.
But it seems that you have to know all your variables by name if you want to use then in a task.
Any idea?
FridtjofIn your IDtsTaskUI.Initialize method, capture the TaskHost. Store it in a field and pass it through to the form within GetView. To get a list of variables in the form, just use the Variables collection that is exposed on the TaskHost.
|||Thanks again Darren,
I got confused by the VarableService which is available from the IServiceProvider in the contructor of the UI form which does not lead to a solution.
I found some sample code in BOL to read out the variable names:
