Hi,

I always get stuck when I try to do readlines. I am writing a program that is suppose to open a file when you click on open file, then the file that it opens should read the first part and do a item add to a combo box. Any help would be appreciated. If you need more info please let me know.

Thanks,

Rachel

System.IO.File.ReadAllLines("./myfile.ext")[0]

Thank you

Yes, I understand it could be done this way...but how would I do it if I don't know the name of the file? The user has to pick the file and when they hit "Ok" the file should be read.

You'd need to use an open file dialog box.

MSDN have an excellent tutorial video series on this sort of stuff. Go to this URL:

http://msdn2.microsoft.com/en-us/vstudio/aa700732.aspx

and then scroll down to the bottom of the page. From memory, dialog controls are covered in Lesson 4.

Regards,

Matt. I

Right. I am using an open dialog box. But once the file is opened I don't know how to read the file to put the first part of the text into a combo box. The code should read the text line by line and put only the first part into a combo box so that when the arrow is selected you should see a choice of 100, 200, 300, etc...

I'll go to the link. I have tried these tutorials, but they do not go into great detail. I hope this one does.

Thanks,

Rachel

The other thing that you could benefit from is probably getting a good book. There are loads around and if you want detail are probably much better than most tutorials on the internet.

Instead of hard coding the filename (System.IO.File.ReadAllLines("./myfile.ext")[0]) just use the dialog's filename property after displaying it. E.g.
