Read A Set Of Names Out Of File And Then Append Them To List Box?

Apr 10, 2012

How would i read a set of names out of a file and then append them to a list box?I am not guaranteed a pair will be on the same line, and not guaranteed that a line would contain a maximum of one pair(i.e., it might have three pairs or it might have one and a half pairs - a first name, last name, and another first name whose matching last name would be on the next line). A line may also be blank.All of this needs to be in a visual basic format.

Read File Names From Directory

Feb 15, 2012

it has been a while since I have asked a question here so I thought now would be a great time to do so. I am creating an application that loops through the file names of a specific directory, in this case, the System32 folder. I want the program to compile a list of the file names and then I want the file names to be displayed on a Timer_Tick event so the name will change on every tick. If anyone could provide a snippet of code to achieve this that would be great. I have been researching and debugging all night with no luck.

List Names From A File?

Feb 14, 2011

how to list names from a file, as you enter (spell) the name. eg if you enter 'b' all 'b' names will appear. If you next enter 'e' then all 'be' names will appear. repeating this until the last letters are entered. eg 'bell' will show all names starting with 'bell'. You can then select from the list the correct name?

Use Relative Paths But Also Read From Full File Names?

Sep 5, 2009

My program has to store files externally to work with. Before now the path was fixed at C:/DSGameMaker, I did the following:

System.IO.File.ReadAllText("C:/DSGameMaker/data.dat")

However I want to let users install the program wherever they want, so I changed that line and others to:

System.IO.File.ReadAllText("data.dat")

Which works great, until you do this:

System.IO.File.ReadAllText("D:/X/Y.Z")

As soon as I put a fixed path into the ReadAllText function it changes the relative path to D:/X. Which means the following function looks inside D:/X instead of the apps directory:

System.IO.File.ReadAllText("data.dat")

And complains that "D:/X/data.dat" is not found.
How can I use relative paths but also read from full file names, for example from an OpenFileDialog, without VB changing my relative path, and breaking it all from then onwards?

Compare List To File Names?

Jan 12, 2011

So in my Textbox I have a list of (folder) names, such as:

Folder1
Folder2
Folder3

I want to compare THAT list to another folder somewhere in someones documents (no specific folder). So let's say we compare it to the 'Arts' folder, which contain these folders inside:

Folder1
Folder2

I want to put all of those folder names in the Art folder into a list. And then I want to compare the folder names in my Textbox to the folder names in the Arts folder, and Folder3 is missing in the Art folder, so I want the textbox to contain:

Folder3

...to tell you that you are missing Folder 3 in your Art folder.

Making A Membership List - Load With Just The Names In The Text File That Is In The Debug Bin

Oct 26, 2009

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

Append An Element To A List?

Dec 15, 2011

I am new to Vb.net so I will need some handholding. I have been searching everywhere but can't find what I need.I'm creating an app that has two forms.Each form has two comboboxes.The comboboxes are populated via a list and the list is populated by reading a text file for each combobox.The second form is called from the main form to modify the entries in the comboboxes. When I select the displaymember in the combobox a value corresponding to that entry is displayed in the text box.Now here is what I need.

I need to be able to append new values to the list so when focus is returned to the main form the new value is present. I'm using a combobox and a textbox on the second form as the import.The combobox is used to either select a present value to be able to modify the value in the textbox, or is used to add a new list element.

VB Code Case Statement - Added A List Box With A List Of Names

Jan 13, 2011

I am used to C like languages such as C#. I added a list box with a list of names. In the code behind I added the below code. When I run the code I am getting the MessageBox but it will state "UserName favorite color is " but does not show the color. I thought it might be misspelled or non-matching names but this is not the issue due to the names being correct.

Read Chunks From A File And Store Them In A List?

Dec 2, 2010

I have a list of files and all of them have a different size. I need to upload them in chunks of 250Kb (or less if it's a small file or if it's the last chunk of a file).What I would like to do is read a bunch of chunks (lets say 15 chunks), in a separate thread, and then store the chunks of data in some sort of list. This list must be available to other threads.

An upload thread (I don't need help with uploading itself) takes the first chunk from the list and marks the chunk as "currently being uploaded". When the chunk has been fully uploaded, then the chunk is removed from the list. A second upload thread takes the next available chunk in the list that has not been set to "currently being uploaded", etc. There are a total of 10 upload threads working at the same time.

As soon as a chunk is removed from the list, then a new chunk of data is read and added to the list.Does anybody know what kind of list I need or how I should do something like this? I don't expect people to write out the code for me, but I have no idea where to start with this.

Array Of Structures Method - Get The File Read And Printed Onto A List Box?

Apr 17, 2012

These are the directions for the assignment.So far I am able to get the file read and printed onto a list box.The book we have for the class does not clearly talk about using the array of structure method with formatting an imported text file.After that I'm pretty much having a bit of trouble with everything else.I know I can figure most of it out but what I'm having a big amount of trouble with is the array of structures that he wants.I know that when I have the file imported that I need to save it temporarily and go through it and at every ":" put it in an array and save that spot and then keep scanning through the file. I know it is going to be a for loop using the index to count through but I'm not sure if how to start it.This is how the text file that he wants sorted out looks.
