Getting at values in a list box

Question

Hi All Simple question I have up loaded information to a list box using the below code List drivers = GetDriverInfo(); foreach (SignedDriver driver in drivers) listBox1.Items.Add(driver.DeviceName++driver.DriverDate++driver.DriverVersion); this displays the data I want to check DeviceName & DriverVersion against some values however I can be sure of the exact location (on my PC it's 29 for the correct entry in the collection) however I can't garuntee it on another (Other PC's Netbooks Tablets etc.) so I want to be dynamic private void button6_Click(object sender EventArgs e) { int index = -1; //USB Serial Converter 2.8.24.0 index = listBox1.FindString(2.8.24.0); MessageBox.Show(index =  + index.ToString()); } while I know there are multiple enteries with this in the messagebox gives -1 not the at least 2 I was expecting. I having been fighting the code too long today! Glenn

Well the FindString() method finds the index of the first item in the ListBox which begins with the string passed to the method. It looks to me like 2.8.24.0 is a version number rather than a device name in which case the method won't find it and return -1.

Thanks for that a nights sleep and I solved it at home got to work read your reply and thought why didn't I didn't get it! Thanks Glenn My solution: int index = -1; //USB Serial Converter20120410000000.******+***2.8.24.0 index = listBox1.FindString(USB Serial Converter20120410000000.******+***2.8.24.0); MessageBox.Show(index =  + index.ToString()++listBox1.Items[20].ToString());
