what is the error message?

[no name] 17-Mar-12 2:15am

sorry my script there is less

private void button1_Click(object sender, EventArgs e)
{
String user = textBox1.Text;
String pass = textBox2.Text;
String status = comboBox1.Text;
WMSDService cf = new WMSDService();
String hasil = cf.checkStatusUser(user, pass, status);
if ((hasil == user) && (hasil == pass) && (hasil == status))
{
Form2 st = new Form2();
st.Show();
}
else {
MessageBox.Show("error");
}
}

while in the press the button, it should show form2. but it appears "messagebox: error". Can you help me?

Your code is checking to make sure hasil is the same as user, pass, and status. Is that right?
