I am trying to load a listbox from a text file, I have debugged the routine and have used the "step into", I have the routine in the Form Load section, it shows the names being loaded but will not show in the listbox itself, please please give me some ideas I have been racking my brain for days on this,

i'm trying to load a sequential text file into a listbox, and for some reason it won't move onto the next line? instead i get square characters instead
It appears like:
Where the square characters are, i want it to be an extra line as opposed to just that? here's the
Dim YOUREFILE As String = "C:Documents and SettingsAdministratorMy DocumentsPROJECTFILESYOURSTUDENTSCORES.TXT"
Dim objReader As New System.IO.StreamReader(YOUREFILE)
[CODE]...
Here's what the file looks like:
I would like to know if there is a quicker way to load a text file into a listbox/arraylist than this:
Code:
Dim fileList as New ArrayList
Dim fileReader As New System.IO.StreamReader("textfile.txt")
Do While fileReader.Peek() <> -1
[Code].....
If I need to load several text files into different arraylists, especially if the textfiles have a lot of lines, this process is very slow. Too slow for my current app to work smoothly, actually.
So, is there any faster ways to load a text file into an arraylist? Or if there isn't, is there some quick way to easily access and change data that is on a particular line in a textbox, so that I don't have to load the text file into an arraylist?
I am trying to load the text file to the ListBox Object. But it doesn't work.
' Initialize an instance of the StreamReader object and declare variables
Dim objReader As IO.StreamReader

Dim intFill As Integer

I have a text file in which there is a list which is composed as follows:
3236, Alberto
5894, Peter
7894: Alonso
and so on ...
What I want is loaded into a listbox the numbers to the first semicolon and load the combobox names.
I created a Right-Click Menu option for files. When the user clicks the menu option it will copy all of the file paths to the clipboard.The following function I have will retrieve all of the filepaths to the clipboard. The problem lies in adding the filepaths to the listbox. If I turn single instance application off the result is multiple instance of the application for each filepath. Say for example I selected 2 files and clicked my right-click menu, I wind up with 2 instance of my exe with each file path added to the listbox, 1 in one listbox, the other file path in the second instance listbox.
Public Sub getthepath()
Try
Dim thefilepath As String
[code]....
Is there a way to loop through each file path from the clipboard and add them to the listbox through a loop?Several times I have tried different ideas I had that I thought would do it and I got odd results but never a good result.
I'm attempting to parse a text file containing several Windows paths; I'd like to use regular expressions if possible, and I'm using VB.NET.The file is formatted somewhat like so:

1.In my program I have 2 textboxes.In first textbox user need to put some number.Let's say he put number 10, then in other textbox program need to write numbers from 1 - 10, like this:
1,2,3,4,5,6,7,8,9,10
If he put 20 in first textbox, in second textbox it should be:
1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20
2.I need to do this...Import text file to listbox.Export items in listbox as text file.
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):
[Code]...
# TAG NAME = is saved to a file using the code below but when I load that same file back into a RichTextbox Control using additional code below, I get inconsistent results as I try to parse the text. Has anyone else had this problem?'Save the contents of the RichTextBox into the file.richTextBox.SaveFile(saveFile1.FileName, RichTextBoxStreamType.RichText);'Retrieve contents of File into RichTextBox control Dim logData As String
logData = System.IO.File.ReadAllText(path + "\" + filenname);
I want to load a csv file (A comma delimited text file) into a datatable. I found the OdbcDataAdapter Class which looks perfect, but it says it is supported only in version 1.1 of the .NET Framework.
Is there a better way to import a csv file into a datatable? the first line has the column headers.
I am using Visual Studio 2008, using version 3.5 of the .NET framework

View 3 Repliesin my program i am trying to make it so that when you press a button it opens a "choose file" popup(where the user can choose a text file) then after the user chooses it the program will automatically load each line of the textfile into a listbox.But i have been researching it and the only thing i have been able to find is a file>open thing. So how cold i make it open a "open" dialogue on the press of a button and since i haven't been able to find anything on the open dialogue i haven't looked for anything on the loading each line of it into a listbox?
View 3 RepliesI'm using the SaveFileDialog to save listbox info into a text file. The files save fine, but when you go to save the file, if you hit the cancel button, it will overwrite the previous file you saved, because it's name was the same and it seems to save the previous file as the new name for your next file. Is there any way to catch if the user clicks cancel, and then exiting the sub if they did?
View 2 RepliesHow do I get my info from a .txt from my website to load into my listbox?! Like if I were to do this...
Try
Dim client As New Net.WebClient
client.Credentials = New Net.NetworkCredential("username", "password")
ListBox1.Items.Add(client.DownloadString("ftp:public_html/listboxitems.txt"))
Catch ex As Exception
MsgBox("Error : " + ErrorToString(), MsgBoxStyle.Critical)
End Try
It just adds a straight line of my multi lines that are in the .txt file...
I can't really explain what I'm trying to say but here is an example.
Example:
Created 1 Listbox named Box1
Created 1 Button named Load

I am working on an assignment where I need to have a product list that is loaded into a list box upon the form loading. This is generated from a txt file in the /debug folder upon loading. Now my question is how do I have the product names show up in the list box when there are 3 separate parts to each product. The product, the cost, and the quantity in inventory, and all I want to show up is the product in the listbox, where the rest show up elsewhere.
CODE:
'This procedure loads the data for the array from txt file. As well as loading the Product.txt file into the system when the program loads.
CODE:
I want to load data from a txt in a combobox and a listbox. The txt is composed as follows:

In the combobox I want to load 'NAME " And in the listbox I want to load "ID"
I am starting to learn reading and writing to textfiles. One quick problem. My code here
'Read is the variable that will read the kp.txt file"
Dim read As IO.StreamReader
read = IO.File.OpenText("C:2/kp.txt"[code].....
however when it is read into the listbox those 3 words appear on one line in listbox
How can i make it so that each line of the textfile is placed in each line on the listbox?
I am having problems with copying from one listbox to another and keeping the paths of the files in the listbox's. At the moment i have two listbox's, listbox1 shows the list of files without the directory paths showing. Listbox2 is used to add items from listbox1 which work ok but what i need is to be able to preserve the directory paths to each file. how to do this and have searched high and low for a solution without any luck.
I have worked out one way of doing it but i think there is a better way of doing it as the reverse does not seem to work. So basicly i want listbox1 to list the files without the paths and pass it on to listbox2 so that the files can be copied to temp directory as they are being add to listbox2.
Below is my
[CODE]...................
Routine to add items from listbox1 to listbox2: I have created another listbox3 (which is in bold), which is hidded under listbox1 and holds all the paths to the files and is use to copy the files from there original directory to a new directory.

Routine to add items back to listbox1 and remove them from listbox2. I have created another listbox4 which is hidden under listbox2 which i was trying add the paths from listbox3.

The end result I am looking for is I want to add File Paths to a CheckedListBox. I only want certain file extensions and if a file by the same name but a specific extension exsists allready then I do not want to add those files to the CheckedListBox.
Example: I am only wanting these filetypes in my CheckedListBox (.gif, .tif, .bmp, and .jpg).However if the filetype (.PNG) allready exsists with the same filename (i.e. image. png and image.jpg) I then do NOT want to add that JPG. Only files that do not allready have a PNG with the same name. (I hope I was able to make this clear)
My current code will add the filetypes (.gif, .tif, .bmp and .jpg) to the CheckedListBox. However I do not know how to have the code only add the files that don't have the PNG.Here is my current code:[code].....

Im fooling around with the Windows Media Player control in Visual Studio 11 (Beta) and I'm wondering how to
1. How to get the path to a folder, and then add all the paths of the files in that folder into an ArrayList
2. How can I get the length of the current .mp3 file that's playing in the Windows Media Player control?
I'm trying to write a program that allows you to; 1) open a mp3 or wav file via the user finding the file and copying the file path and pasting it into a text box and, 2) by pressing a button it will play the desired file, and then 3) by pressing another button it will stop playing the file. I've already have this under pat,
Private Sub cmdOne_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdOne.Click
My.Computer.Audio.Play(My.Resources.buzzer, AudioPlayMode.Background)
End Sub
I am working on a project and transferring the whole project back and forth. The thing is I am using a full file path in all my code ("c:/Users/..."), so when I transfer to the other computer the file paths break. Everything I am linking to is in the "bin" folder in my project's folder. How do I have file paths relative to the project folder?
View 2 RepliesI'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..
