I've been developing a arcade game, and as every good arcade game, it has an incorporated scoreboard so that players can see who scored better. My problem is that everytime it enters a new scoreline, it deletes all the previous lines in the text file. The code I've been using is the following:

I have a very large text file about 4 million lines that I would like to separate into several small text files based on the strings contained in the first column of the text file. I want to open the large text file, choose the lines that apply, create a new text file with a name that has a number at the end of which will match up with the value in the first column of the text file. I want to then copy the applicable lines to the new small text file, save and close it. I'm not sure how to go about doing this after opening the large text file and using the readline method. What if the folder does not exist? Do we have to create it? I want this procedure to be general, as there could be up to 25 million lines in the text file.

This question is a little more in depth than the typical append and save. I'm needing to append multiple controls text to 1 file. Basically what I have is:User inputs name in TextBox1 User inputs Service Type from selected list in ComboBox1 User checks of any or all CheckedListBox fields that apply. Now, all together, there are actually between 4 to 6 different checkedlistboxes.What I am wanting to do is when the user clicks the Submit button (Button1), at the bottom, it will write a text file of TextBox1.Text,omboBox1.SelectedItem.ToString, and all the checkedlistbox items.Now there is a small thing I may have to start another question on. For every checked item in a checked list box, I would like to writ

View 2 RepliesI want to append a text file with items from a listbox. I tried to search for a code to do that, but couldn't find anything(most likely I don't know what I am looking for). But I wrote this code and got it to work, but after looking at the code, it looks sloppy and I'm sure could have bugs I didn't catch....my question is, is there a better code than the one I made, or will my code work fine. I am eager to write code correctly, not just get the code to work.

I am trying to create a textfile if it doesn't exist or append text to it if exists in vb.net.
For some reason, though it is creating the text file I am getting error saying process cannot access file.

I am trying to append a new line to a text file. Sometimes it posts to a new line (like I want it to) and sometimes it appends to the current line, consequently screwing up my read. I even put VbNewLine in the code.
Here is the snippet:

outputline2 = equip & "," & value
Dim myfile2 = File.AppendText("equiped.txt")
myfile2.WriteLine(outputline2, vbNewLine)
myfile2.Close()

I need to create a timer that sets the time from an existing text file. The time format in the text file is 00:00:00 (hours,minutes, seconds). An excerpt from one of my text files looks like ClockSet = "00:49:05"
Also, if possible, when the timer reaches 2 minutes I would like the backcolor to flash between red and green.
