Alright, im trying to load a text file into a list box using a delimiter(sp?)I have 2 list box's lstFirstName and LstLastName I have the code to load it into a list box
r = New IO.StreamReader("c:\test.txt")
While (r.Peek() > -1)
lstFirstName.Items.Add(r.ReadLine)
End While
r.Close()
And at the moment this will just load the whole list box, how can I use a delimiter to split it up?So John Doe in the text pad will show up as lstFirstName: John lstLastName: Doe Sorry if im not all that clear, if you dont understand I will try to explain it clearer.

I'm trying to Load data from a Text file, which is "," Delimited into 6 List Boxes.. Want a FileOpenDialog Box so that the user Can chose which Office Id txt File they wont to load into the List Boxes.How it works is;
-The user Enters an Office ID (e.g HH33)
-The user fills out the rest of the program, the data is then generated into the 6 list Boxes
-User then clicks Save to File button.
-The program creates a Text file with the name coming from the Office Id, so if the user enters HH33, the text file is created with name HH33.txt.
-All Data entered by the user under the office name HH33 will be added to the Text File..[code]
Here is the code for my program. We are making a membership list and it needs to load with just the names in the txt file that is in the debug bin. The txt file is set up in one column and holds the member name and the next line is member number and so on. Information is read into an "array of structures" and the display is supposed to be ONLY the names in the listbox on load. This is my problem. I had it displaying all th txt file info and I just need the names. I tried what you will see in the code but it is not working and my book is less then helpful when it comes to examples and/or knowledge on the subject. Though it could be too many hours spent trying to get it to work.
Imports System.IO
Public Class frmMemberList
Structure Members
Dim member As String
Dim number As Integer
End Structure

I need to load a large txt file that is in a fixed width format. There are over 45K lines, so speed is important.I need to load one of the fields into a dropdown box and have another field (label) display the text of another field in the related line.I could import the file to an access db if needed, but would rather not as i also want the txt file to update from a link on a regular bases. So having it in a DB would be more work to process that part.[code]

I've been literally googling for an hour now trying to find how to save variable settings to a file.I'm writing an application and I'm using alot of changeable variables. I want to be able to save these to a file so they can be loaded at application startup. I don't feel like using the regestry since I hate to write unimportant things to the registry.I remembered that I found a good example with simple code of how to do this with xml, but I can't seem to find the example now.
View 10 RepliesI am looking for a way to save and load the values of all my controls present in my form.My form has around 100 controls spread over 7 tabs. The controls include (Multiline) TextBoxes (Strings), NumericUpDowns (Integers, Decimals) and Checkboxes (Booleans). If the user clicks the save button a "Save File" dialog should appear allowing the user to specify the directory and the filename of the save file.All the values of the controls should then be written to that file.If the user clicks the load button an "Open File" should appear where the user can pick a previously saved save file. All the controls should then adopt the values found in the save file.I have implemented Application Settings in my form, and now when I click save, it saves the control values through My.Settings.Save(). If I click load it loads them.However, my project requires that multiple save files can be made to reflect multiple configurations. As I understand Application Settings only allow for a single .config file in the Application Data folder.So how can I code a save/load routine to save/load different configurations?

Before I begin I would like to mention that I am not a noob in VB, it's just I've never had to do anything this complex before. Basically what I want is to have a program that you can load a txt file in, have it copy key words, and paste it in a textbox so I can use it later on. So in this text file, there is a bunch of info, but I am only needing a certain part. Here is an example of a text file (actually a .dat file, but is easily read):

My intention is, to input a text file name and location in textbox1 and the button loads the text file in textbox2.
I've been staring at my code for a few hours, and cannot think of the next part.For my final I need to make a hangman program Pretty much I have a button to load a .txt, a label, a multiline textbox(which will be hidden later), and a normal textbox. I need the program to load the txt file, and randomly select a word. Then have the program put a " - " for every letter in that word The program loads the txt file,to the multiline textbox,but I don't know what to put next. EDIT:After looking at my book i noticed it shows how to make a hangman program, but without loading a text file. So, all I need is the code that will make it select a word randomly from the list, and i think I can do the rest..
