I tried this:

if (comboBoxLabNumber.SelectedIndex < 0 | comboBoxProblem.SelectedIndex <0)
{
MessageBox.Show("Please select the lab number and the problem");
}

string LabName = comboBoxLabNumber.SelectedItem.ToString();
string LabNumber = LabName;

string LabProblem = comboBoxProblem.SelectedItem.ToString();
string LabProb = LabProblem;

Yes, it works. However, this message of "Error: Object reference not set to an instance of an objet." still comes out.

I'm blur. Does it mean this way?

if (comboBoxLabNumber.SelectedIndex > -1 | comboBoxProblem.SelectedIndex > -1)
{

}
else
{
MessageBox.Show("Please select an item!");
}

string LabName = comboBoxLabNumber.SelectedItem.ToString();
string LabNumber = LabName;

string LabProblem = comboBoxProblem.SelectedItem.ToString();
string LabProb = LabProblem;

I tried this:

if (comboBoxLabNumber.SelectedIndex > -1 | comboBoxProblem.SelectedIndex > -1)
{
string LabName = comboBoxLabNumber.SelectedItem.ToString();
string LabNumber = LabName;

string LabProblem = comboBoxProblem.SelectedItem.ToString();
string LabProb = LabProblem;
}
else
{
MessageBox.Show("Please select an item!");
}

However, it comes out as error : The name 'LabName' and 'LabProblem' does not exist in the current context.

I've managed to get what I want. This is my code:

using (StreamReader sr = File.OpenText(@"C:\config.txt"))
{

String input;
string[] lines = File.ReadAllLines(@"C:\config.txt");
while ((input = sr.ReadLine()) != null)
{
int i;
// if ((input = sr.ReadLine()) != null)
for (i = 0; i < 2; i++)
{
input = lines[i];
}
}
MessageBox.Show("COM Port is " + lines[0]);
MessageBox.Show("Phone number is " + lines[1]);
}

thatraja, this is what I'm trying to do:

using (StreamReader sr = File.OpenText(@"C:config.txt"))
{
String input;
string[] lines = new string[2];
while ((input = sr.ReadLine()) != null)
{
int i;
if ((input = sr.ReadLine()) != null)
{
for (i = 0; i < 2; i++)
{
input = lines[i];
}
MessageBox.Show("COM Port is " + lines[0]);
MessageBox.Show("Phone number is " + lines[1]);
}
}

}

However, it's not working. MessageBox does not appear the comport and phone number. :-(
My main problem now is how do I assign each line read from the file as a string variable.. Please help.

Thanks.

(btw, from my reading, i still dont quite get the concept of stringbuilder :-( )

thanks thatraja!
