i get this error in this program.
'dTemp' is not a member of 'Decimal'
'out' is not declared. It may be inaccessible due to its protection level
Comma, ')', or a valid expression continuation expected.
'dTemp' is not declared. It may be inaccessible due to its protection level.

yes the dTemp if from c# but i cant figuer out how to change it so it work in

This line:

Decimal.dTemp = 0

There shouldn't be a dot there; it tells the compiler to look for a member of Decimal called dTemp .

You meant this:

Decimal dTemp = 0

But that's C#... how about:

Dim dTemp As Decimal = 0

thx for the help
