I dont mean to be rude but I would reccomend looking at the MSDN Docs or the .net Framework SDK.

If you look up System.Windows.Forms namespace in the .net Class reference section you should find the ComboBox class with all the methods and properties all documented in great detail. There are also lots of examples given in the .net SDK docs.

If all that fails and you have no idea then try google. Its all too easy to just ask in a forum. I have been reading this forum for about a year and I think if people read documentation and utlised google more there would be less need to post simple questions. You might take offence at what I have just said. I did not intend any and am only trying to help you become a better programmer.

I tried google and maybe i wasnt searching for the right stuff but i could not find anything useful. I will try the MSDN Docs (i forgot about those). And no you were not rude

crawforddavid2006 · Sep 11th, 2006, 5:03 PM

I can't seem to find anything in the MSDN Docs. Would someone be able to help me?

Comboboxes take single lines. If you want to add each line as a new entry into the combobox, do just that: split the text up (myString.Split('\n')) and add 'em all separately.

ok i tried this but it gives String[] Array in the combo box

[php]
sr1 = new StreamReader("c:\\collection.txt");
string myString = sr1.ReadToEnd();
sr1.Close();
comboBox1.Items.Add(myString.Split('\n'));
[/php]

You have to add them one at a time, I'm afraid.

 csharp Syntax (Toggle Plain Text) 
foreach (string Line in myString.Split('\n'))
{
    comboBox1.Items.Add(Line);
}
foreach (string Line in myString.Split('\n'))
{
    comboBox1.Items.Add(Line);
}

Can't you do the following:

 csharp Syntax (Toggle Plain Text) 
string myString = System.IO.File.ReadAllText("c:\\collection.txt");
comboBox1.Items.AddRange(myString.Split('\n'));
string myString = System.IO.File.ReadAllText("c:\\collection.txt");
comboBox1.Items.AddRange(myString.Split('\n'));

Thanks Jason_Isom. Your suggestion worked.

crawforddavid2006 · Sep 12th, 2006, 2:14 PM

I lied... that is not the end of my problems

. What Jason said does work but it leaves a little rectangle shape after each line. I tried using \b after the \n but it will not accept that. Any Ideas?

The split removes the \n if that's what your splitting on. Is it possible the \n you're getting is an 0x0D 0x0A and you're only removing the 0x0A ?

Here's two suggestions, do a .Trim on all of the elements (which would still require looping) or before the split replace the 0x0D 0x0A's with 0x0A's so that the split on \n works properly.
