Hi
I keep getting the error description of "Invalid Number of
Paramters" when I try to re-open / execute my save DTS package that
contains a custom task which work fine when I first start my dts
package. I also get this from an example custom task which I download
from Microsoft site (which uses the UI). I come across this problem
before when writing customs task VB6 which was I had read only
properties but none of my .Net custom tasks do. Has anyone easy come
across this problem and be able to solve it ?

Do you implement CustomTaskUI or not ?

If you don't you need to work around the fact that ToString is getting
exposed as a COM method, since it is a method on System.Object which is
where every object derives from.

Workaround for that problem is to override ToString like this:

<ComVisible(False)> _
Public Overrides Function ToString() As String
Return MyBase.ToString()
End Function

Sorry your are using C#

// prevent ToString from getting exposed as a COM method
// not required if CustomTaskUI is implemented,
// added for completeness of the sample
//
[ComVisible(false)]
override public string ToString()
{
return base.ToString();
}
