I have lines of text throughout the file that contain paths to other "different" types of files. I am looking to remove any text between "/" markers inclusing the markers themselves. such as "/path/"Everything I have come across list a streamreader and a streamwriter that list two different files and bla bla.

All I would like to do is remove one character from the line of the text file that I am reading, which is the first character and also prevent the program from crashing if no text file is present.Here is the code. Can anyone notice where I am going wrong? I thought the "if" statement would cover the crash but it didn't. Clueless, but sort of have an idea on the character removal.
Private Sub RadioButton_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RadioButton.CheckedChanged
Dim fileReader As System.IO.StreamReader
Dim lineRead As String
If RadioButton.Checked Then

I have this Quiz software that lets you create online multiple choice quizzes which are great for studying (I am in grad school and I'm trying to use everything I can to learn). So the Quiz software is great but it only lets you input questions by hand, one by one. I took a look at the .xml file that the quiz program spits out and came up with the idea to try and make a converter so that I can import many questions at once. I was hoping to try and solve this limitation by doing the following:
Take a .doc that say a tutor gives us with a bunch of practice questions, and then take that into Crimson Editor, and then format it so the question is on line 1, the multiple choice answers are on lines 3,4,5, and 6, (for the next question, the question would be on line 11, and the answers on lines 13, 14, 15, and 16, and so on) and then take that saved .txt file into my program, hit the generate button, and it will spit out the .xml file, and then import that into the quiz software to generate the online quiz.
Here is an attached screenshot of my program layout so far:
I figured out how to open a text file by watching simple youtube tutorials, but I don't know how to have it generate the stuff and have it show up in the bottom text box. I know how to do the coding to convert the txt to proper xml code but I don't know how to be able to save the contents of the bottom text window to an xml file.

Write a program that requests a color as input in a text box and then determines whether or not the color is in the text file. The program should use the Boolean-valued Function procedure IsCrayola that returns the value True if the color in the text box is a Crayola color.
*I am to use a file named Colors.txt

I have two text files. The fields in each text file are separated by a space (" "). Some of the fields in column 1 of file 1 match the fields in column 1 of file 2. However the third column in file 2 is a numeric field. What I wish to do is check every field in file1 against the field in file 2, and if the number is 1 then remove the row from file 2, if the number is > 1, then subtract one from it.
I have the following coding so far.
Dim lines1 As New List(Of String)(IO.File.ReadAllLines("File1"))
Dim lines2 As New List(Of String)(IO.File.ReadAllLines("File2"))
Dim values As New Dictionary(Of String, Integer)()

I know there's ton of examples on the forum but i could not get it to work the way i want.
Sample CSV :-
Unused,172.22.21.2,SD103001
Unused,172.22.21.3,SD103002
Unused,172.22.21.4,SD103003
And what i wana do is change the Unused to Used so basically once this is done it will look like.
Used,172.22.21.2,SD103001
Unused,172.22.21.3,SD103002
Unused,172.22.21.4,SD103003
One thing to mention is i dont want to loop through the whole file and change all the Unused to Used. So basically software fires up opens the file and looks for Unused and changes it to Used and does the rest of the function and shuts down. Next time the software is fired up it goes through and does the same thing.

my program can add new lines and select url's but I can't get the remove button working, I read that (maybe) I have to read all lines and write a new file.
If removename = currentfield Then
Dim removedata As New System.IO.StreamWriter("z:station.list.txt")
removedata.Write(""(currentfield))

It puts the file in the listbox with no errors.
