I execute a stored procedure out of VB4.
In this stored procedure there is a SELECT FROM statement.
The problem is that I wanna use the sp to select from different tables. So there is my question:

Can I supply the tablename as a varible?
for example:

sp_get
@tablename char(25)

SELECT * FROM @tablename

No you can't use a parameter for the table name.  A stored procedure is compiled to present an optimized query plan, based upon the tables involved and the columns access/filtered.

The best you can do is to create multiple differently named stored procedures (name them based upon table target table name), and then use a variable name to substitute the procedure name that works with the table you desire at run time.

Yes you can use tablename as a parameter.

CREATE PROCEDURE testt @tabname varchar(30)
AS
DECLARE @sql VARCHAR(100)
SELECT @sql="SELECT * FROM "+@tabname
EXEC(@sql)
