                  SqlDataAdapter myCommand = new SqlDataAdapter(SqlStatement, myConnection);
                  return myCommand;
}
// Connection takes in a string that is what you are searching for

public int SqlRowCheck(string SqlQuestion)
            {
                  SqlConnection myConnection = new SqlConnection("");
                  SqlDataAdapter myCommand = new SqlDataAdapter(SqlQuestion,myConnection);
                  DataSet Check = new DataSet();
                  myCommand.Fill(Check,"TABLE NAME");
                  return Convert.ToInt32(Check.Tables["TABLE NAME"].Rows[0][0]);
            }

// this assumes that you are locking with just an int value on the table. Without a better knowledge of how your design is set I can't get a more specific answer

in a function call this.

int Locked = 1;
while(locked != 0)
{
locked = SqlRowCheck(YourSearchString)
// delay can be done if you want.
}

SqlDataAdapter Connection(string SqlStatement);

SqlException is what I think it throws.

so do this.
try{

blah blah blah

}
catch(SqlException error)

then you can catch and handle the exception right there. Your app will know it failed. if it fails have it loop.
