Sort Items Before Being Written To A Text File?
Apr 18, 2012
Let me preface this by saying that I'm very much a novice coder. I'm currently working on a small project to practice with Visual Basic and have experienced some issues during my save and load process using text files. I think I can solve the issue by changing the way my text file is initially saved. I want to see if I can sort the items and change the order in which they are written to the text file based of the value in one of the lines.[code]....

How can I improve this bit below to make the items in the TreeView to sort faster or something totally different to sort them easier?

I tried to write a text written in my textbox to file.(a .txt). I scanned it to see if it contained any illegal characters, the program said that it did not. However, when I went to save it it said that the program performed an illegal operation.
System.Runtime.InteropServices.COMException was unhandled Message: Exception from HRESULT: 0x800A0005 (CTL_E_ILLEGALFUNCTIONCALL).
It created the text file but did not write the content of the textbox to the file.I can save the text in Microsoft word without a problem. Is there something wrong with the encoding for the textbox and how do I set the encoding for the characters so I can write it to a text file.

i am trying to create a program which will get data from the .txt file. I got to stage where program gets me the information from the .txt but i would like it to be sorted.
Here is sample of text in .txt
01:13:11 Setting up 01:13:11 Loading level 01:13:12 Now accepting input on 25565 01:13:13 Level saved! Load: 0/16
I want it to take a new line after the time so it would look like this.
01:13:11 Setting up
01:13:11 Loading level
01:13:12 Now accepting input on 25565
01:13:13 Level saved! Load: 0/16
The code in visual basic that i use now for inputing the text file.
Dim FILE_NAME As String = "C:Documents and SettingsAdministratorDesktopmcserver.TXT"
Dim objReader As New System.IO.StreamReader(FILE_NAME)
TextBox2.Text = objReader.ReadToEnd
objReader.Close()
Why do i need it ? This is a log from command promt, this app will be for a game server.

I have a text document that contains a bunch of data sets. However before each data set there is a number surrounded by brackets. I need to go instance by instance of brackets and pull the number between the brackets and the lines after the brackets until the next bracket. Here is an example of the text file that contains the data. I know how to read from a text document, do substring, do contain function, etc... I just am extremely stumped on how to do this. Here is an example of a couple entries of the text document...
[4188]
LongName=
ShortName=
LauncherDirKey=
[Code]....
Notice how different sections have a different amount of lines therefore a reading a fixed number of lines is not an option.

I have a simple text file containing a list of names that I wish to sort. I was hoping for something simple like:
System.IO.File.ReadAllText("MyFile.txt")
System.IO.File.Sort("MyFile.txt")
System.IO.File.WriteAllText("MyFile.txt")
or something like that. Didn't want to actually write a bubblesort/quicksort routine myself.
I would imagine the routine would just rewrite the final file or would I have to make a new file and copy the contents back to the original?

I add strings (items) dynamically to a ToolStripItemCollection by:
Dim onClickHandler As System.EventHandler = New System.EventHandler(AddressOf Symbol_Click)
Dim item As New ToolStripMenuItem(newSymbol, Nothing, onClickHandler)
SomeToolStripMenuItem.DropDownItems.Add(item)
So the items are not added in one go, but one-by-one based on external triggers throughout the program session. I would like to sort the drop-down-list every time I add a new item. What are my options to achieve that?

I am trying to sort a treeview, base nodes, which is the first base set you see before you click any + sign's I am trying to sort by alphabetical order, but, for the nodes inside each + view of the tree's I want to sort by number order, the number is currently set to the tag as text version of the number. Anyways, for the nodes in the + view's I need it to be able to skip over numbers if not every number in sequential order is there, so if number 4 is missing for example, still sort 1,2,3,5,6. My full code is pretty big but just retrieving items to display is random & I just add items as they come in, now they don't come fast or even when your not expecting new things to appear so it should not matter how it works really as it wont be updating as they are using the treeview.

I have a question about efficient implementation. Lets say I have two arrays:
One array is all possible items in a house: Table, Chair, TV, Fireplace, Bed
The other is an array of items in a particular house: Table, TV, Bed
I also have two list boxes:
1. listbox for items in the house - the "HAS" list box
2. listbox items not in the house - the "NEEDS" list box
I need to list the items already in the house in the "HAS" list box as well as the items that are NOT in the house in the "NEEDS" list box. It seems to me that nested "For each" loops would be a start to solving this problem but I am not exactly sure which case needs to be nested.

I have a program that can save to a .txt file.The issue is I need it to be done in a tab delimited way.Basically:
TextHere<Tab>TextHere<Tab>TextHere<NextLine>
TextHere<Tab>TextHere<Tab>TextHere<NextLine>
I have this so far, but all it does is put the TextBox1.Text next to TextBox2.Text
Code:
SaveFileDialog1.Filter = "Text files (*.txt)|*.txt|All files (*.*)|*.*"
Dim FileWriter As StreamWriter
Dim results As DialogResult
