error with parameters when inserting data in oracle - vb.net

Question

good afternoon,
I've been wanting to insert into oracle for several hours but I have a message that refers to the
parameters, I'm testing with a table with only 2 columns to test, but I can't find the problem.
Please appreciate any help.
error code: ORA-01036: INVALID NUMBER / VARIABLE
***The connection to the database is correct.
***Try the insert without the ID column, with the same result.

You are using SQLSERVER syntax for parameters "#" but in Oracle it's different, you have to use ":"
