Displaying Directories And Contents In ListBox
Aug 29, 2009
Recently I have browsed the web for ways to display a list of files and folders in a list box. I have successfully been able to display files in drive C and get a nurerical value telling how many files were found. However my efforts have been hampered by three distinct problems. I have some experience using batch files and when using them you can state things like "%WINDER%" to go directly to windows folder. I am wondering if there's anything like that used for navigating. And if so could an example be made of it just for clarity?
My second problem is I cant seem to be able to display files and folders. I have been limited to one or the other. That and I cant figure out how to navigate into them to display there contents. The next problem I have is simply having a user interface so you could type a file path or file extention and have the program navigate to it. Is it is possible to click a file path in a list box and chose to delete it. My second last Q how do I display all files and folders including hidden files? And How can I count all files and folders with there contents to dissplay in a listbox.

I am currently creating a little application which will essentially backup my work I do at college. It works by me saving all my work onto a flash drive. When I run the application it will copy all the contents of the flash drive and copying to my college directory and when I'm at home copy to my Dropbox folder. This essentially gives me 4+ areas where my work is saved. Unfortunately, the college computers due to network restrictions and other problems, the use Dropbox on the college machines (I obviously can still access the website).

I'm having a problem when I list .rar-files into a ListBox. I can list .rar-files OK from subdirectories, but what I want to determine if the file is actually the first part of .rar-archive. The new .rar-format packs files like:
Archive.part01.rar
Archive.part02.rar
Archive.part03.rar
...
So I have no idea when I'm listing the first part of the archive or actually listing the other parts.
Function UpdateFiles(ByVal FolderPath As String) As Boolean
'If FolderPath is empty, return false
If FolderPath = "" Then
Return False
End If

I am having a hard time displaying the contents of a text file that i read into an array. I read the text of the text file into an array but then i need to display it but i can't seem to get it. I also need to create a criteria to match whatever letter is entered into the textbox and display the contents of the file only beginning with that letter. I know i have to use a substring to read only the first letter but I can't even display the contents of the file from out of the array. Here is what i have so far.
Dim sr As IO.StreamReader = IO.File.OpenText("CRAYONS.TXT")
Dim color(50) As String
Dim arrynum As Integer

I am having a problem displaying a custom array list I have in my code. (BTW. It is 1am where I am. I have been at this for a long time so I apologize if I don't make a lot of sense).I built an arraylist of objects from a custom class. The arraylist contains 2 columnsdimensions.The first is type string, the second decimal.I am now attempting to take my arraylist and display it in my form. I have tried using a listview and iterating through it, but unsure of how to split the two columns up. I have tried something similar to the following I found in another forum:
Code:
For i As Integer = 0 To arSearchArray.Count - 1
Dim item As String = CType(arSearchArray(i), String)

I'm working on a program that will be a semi-autosubmition in web directories. I need an ideea for my directory list.I want to able to navigate from one directory to other with a "next button". Now I'm using a listbox saved in a text file, but i don't know how to make the selection for "next directory".I'm only able to click on the list. And what I thinking was if it is posible to have a better list, advanced, like a table with more columns like: url, if url is valid, pagerank for example, and maby sort by this filtres.

I'm working on a site that I've inherited that's built with ASP.Net, which I'm only slightly familiar with. One of the pages allows for a link to a document (word or pdf) that, when clicked on, prompts the user to save or open the file, but does not reveal the true path of the file. This way it prevents users from pasting a url to a file - the link is to an aspx file that checks for a valid session, and then retrieves the file.
Anyway, because there's a lot of legacy code, I need to do this with a bunch of static htm files as well, however these files need to be displayed rather than prompting the user to save them, which is what happens now. I tried changing the content type to application/text, application/html, text/html, etc. and that didn't work, then tried adding a response header of content-disposition inline. When I do that, build, and try linking to the file, I get a couple of runtime exceptions:
[FormatException: Input string was not in a correct format.]
Microsoft.VisualBasic.CompilerServices.Conversions.ParseDecimal(String Value, NumberFormatInfo NumberFormat) +206
Microsoft.VisualBasic.CompilerServices.Conversions.ToLong(String Value) +110

Do I have to do something with an htmlwriter object or something? Can't I just have it open a new browser window with the file displaying or does it have to prompt the user if used in this way??

I'm working on a desktop replacement project and was wondering if it possible to have a form which can be docked to the side of the screen that contains all the task tray icons and functions (I would imagine that the functions are held within the task tray/icons themselves as they act as little programs) and would update automatically whenever anything is added.
Also, I'd like it not to have a taskbar entry while running, just having it sit there on the screen until needed.

The above code reads all the files & directories in a selected path. It ignores any hidden folders, like it suppose to. Except it doesn't ignore folders inside of the hidden folders that it finds & I need it to.I can't quite wrap my head around how to make it ignore all folders & files inside of a hidden folder that it find.

The user enters information into a textbox, and if it is present in the litsbox an error message will be displayed, if it is not already in the listbox then it will be added to it.
I save what the user enters as a variable and i am wondering if its possible to check the exact contents of a listbox?

Been trying to figure out how to do this for a while, but I can't seem to find anything that exactly covers what I'm trying to do. I'm really a novice when it comes to vb .net, so this might be staring me in the face and I wouldn't know it.I've got a Motorola MC3090 mobile barcode scanner running Windows CE 5.0 at work. I wrote a small program (in .net 3.5) that allows me to scan barcodes and then get counts for specific barcodes when I type all or part of the barcode into an textbox. That works pretty well for receiving, but I need something that works better for the reverse process (shipping things out).
I have an textbox which accepts the barcodes. When the scanner emulates an enter key press, it adds the code to a listbox and clears the input field. This process loops as many times as my quantity field specifies. There's another textbox which I use to input partial barcodes that I want counts for. It looks for strings in the listbox that match, dumps them into a second hidden listbox, and counts those.
If you're the tl;dr type, here's the short of what I want to do with all of the above. I want to take the contents of the visible listbox, summarize by listing each unique barcode, and have a count of how many of each unique barcode appears in the listbox.

I have a listbox control (in a WinForms application) that lists a bunch of statistics about records selected from a database.
Is there an easy way using VB .NET to take the contents of this listbox and send it all to the printer, or at least have one of those standard windows print dialogs come up, prompting the user for which printer to send the listbox contents to? Doesn't have to be fancy or anything.
