Searching And Deleting Files (using Wildcards)
Jun 29, 2009
how to even start a code project of this sort but here it goes... I have an external Hard Drive with some music. My itunes makes duplicates of all my songs so this is what i have.
Dance.mp3
Dance 1.mp3
Dance 2.mp3
Dance 3.mp3
Party.mp3
Party 1.mp3
[Code]...
What I want to do is have the program search the files and delete all files that have a duplicate with a number behind it... Now I would use windows search but some of the songs are like 1001.mp3 or 1001 1.mp3... I want it to look like this when i get done (from the above):

I know how to search a text file for a specific line, but what I don't know is then how to delete that line?My text file is set up as such:
021,Donovan,56 Eynesford Crescent,Bexley,SE5 1TR,09/08/1967,13 March 2012,Bronze
062,Fredrikson,6 Freil Road,Gravesend,GR9 TRB,12/06/1995,13 March 2012,Silver
So I know how to search for the 3 character integer at the beginning of each line, but how do I then delete this line?
I'm currently using this code
Imports System.IO
Public Class Form6
Private Sub SearchBtn_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles SearchBtn.Click

I have seen questions like What is the best way to empty a directory?
But i need to know,
what is the fastest way of deleting all the files found within the directory, except any .zip files found.
Smells like linq here... or what?
UPDATE: By saying fastest way, i mean the Fastest execution time.

vb 2008 on Vista: I have a folder called "Documents", and another called "PastDocuments". When the user deletes a client, I copy the contents of Documents into the Past Documents folder. Next, I need to delete the Documents folder, but there are existing files within that folder, so it won't let me delete it. What is the easiest way to delete ALL files within that folder?

I have some code that launches a .bat file. The error comes from within the .bat file, navigating to the specified directory."F/Program Files/ Tversity/Media Server/data/ if i run cmd, then manually navigate to F/program files, i cannot navigate into any other directory within program files. Wierd..if there is an easier option to just use vb.net without launching a .bat that might help please let me know. i know i am not showing any vb.net code, but it just launches a .bat file. i know the forum rules, but i am hoping that someone might know why i can't navigate to my program files. it is not permissions, i am an admin on the local machine no domain.

So I have a program that allows the user to load up some images, which appear in a ListBox. You can click the imported images and they load into a PictureBox. [code]The path is not of a legal form.You can load up the code and see for yourself. Now I need to be able to delete these images from the ListBox. The exception occurs because the image is now null, and can't load.

I'm experiencing a wierd problem deleting some .csv files. Any .csv files named 1.csv, 2.csv, or 3.csv will not delete using delete() method of system.io namespace. if i do any number greater than 3 it works. For example, 4.csv, 5.csv, etc. works fine. 1.xls, 2.xls also is ok. The error it is throwing in my log is 'access to the file is denied.' Nothing is using the file. I even copied a new file into the directory and it does not work. I even created a 1.csv in a totally different directory with no luck. What is going on with this? Has anyone ever experienced this?

I can search all the images with .jpg extension and pass it to the fancybox gallery , The issue is i just want the images of particular productid for instance if a product has 5 images , and they are saved as (productid_imagenumber.jpg) , therefore a product with productid 99 will be saved as 99_1.jpg , 99_2.jpg similarly 99_5.jpg,I can pass the productID but i cant find a away just to get the images of that productID , instead of getting all the images which is done by the function below:
Dim directory As DirectoryInfo = New System.IO.DirectoryInfo("C:Images")
Dim allImages() = directory.GetFiles("*.jpg", SearchOption.AllDirectories)
Dim strContent As String = ""
For Each image As FileInfo In allImages

I'm creating an app that has check boxes that will define a search. The files all reside in one folder. I've looked at some tutorials that use io.directory.getfiles and I can get this to work. But what I think i want to use is: io.path.getfilename because I don't need the path (though I'm about ready to make an exception).
When should I use io.path.getfilename and can I use that method to do a search? I can't figure that out. I would think it would react as io.directory does but I am incorrect.....
Here is the code. Its short becasue I'm just figuring things out first:
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim afiles() As String
[Code]....
The commented out line is what I can't get to work and I'm thinking that is what I need to work.

On a image file (PDF), the OCR has recognised the picture and text. However on Visual Basics, how do you search for a text on this image file? The primary goal is to allow a text search (i.e POxxxxx) on all the image files (PDFs). The returns of the search will be the assciated image files where the text (i.e POxxxxx) is found on.

Each time it runs, a program of mine creates an Excel document and names it using the current date ("Alerts from 29062011.xlsx" for example). The program gets run once a day,every day.The users have requested that I have the program delete the previous days Excel file each time it runs so that they don't take up space. I'm unsure how to do this though since, for example, if it is run on the first day of the month it would have to know

My naming convention for certain files is ------------kill 28 nov 2010.ext Is there a way I can throw an if statement and a few variables together to check each file in a folder and if date.today = variable then delete file? I want to make a program i can schedule to run daily w/task scheduler, I haven't used VB in awhile but just found the disks from school so i figured this was the easiest way to go about it.

I am concatinating a couple of text files and then deleting the individual files. (Not the output file)
The only problem is that I am getting a permission error "Exception from HRESULT: 0x800A0046 (CTL_E_PERMISSIONDENIED)" when I try to delete the files.
I can delete the files using the code below if I do not concatinate the files but as soon as I do I cannot delete them.
To concatinate:
Public Sub MeltText()
Dim SW As New IO.StreamWriter(OutPutFile)
Dim Files As String() = IO.Directory.GetFiles(StartDirectory, "*.txt")
Dim File As String
SW.WriteLine("Sw

I have created a project where I can attach files and I am displaying the name of the file, example:
Mytestfile.doc
mytestfile.txt
Mytestfile.pdf
I have the names being displayed on a listbox, so far everything is working just the way I expected to work.When a file is selected from my opendialogbox, the file gets saved into a folder under my local disk, so far so good.The problem that I am having is deleting the file from the folder.I have added a delete button and I would like to when I click or highlight one of the file names to go into where the file was saved previously and deleted This is the code that I have for the delete funtion:
[CODE Dim sFileName As String = "C:program filesSupport DeskAttachments" & ListBox1.Text
System.IO.File.Delete(sFileName)][/code]
The problem is that if I add the code to the clcik event under the listbox, it works great, but if I add the code to the click event under my delete button, it doesn't work, what I found is that under the path, if I am under the click event from the listbox when it gets to the lisxtbox.text it displays the file name, which is what I whant, but when i tried the code under the click event under my delete button the listbox.text is blank.

I have a series of large files (4GB) that when I delete takes a very long time. This only occurs on a USB drive that I have attached to my PC. If I do the same thing on the internal drive the files delete quickly. It is as if the files are being overwritten before being deleted. I am looking for some guidance or other approaches.

I want a form to search a directory (which i specify in the code) and then list all files with a file exstension that is .amxx .And that's not all, it should list them in a checked listbox.And of course a little + is that it only list the name of the file, not the hole directory + filename. But that feuture i don't really need, just for good looking.I looked into the problem and i tried something with DirectorySearcher but with no success.

I need to scan all files on our solution (aspx, js, ascx, etc). Our solution contains 22 projects all in all. What I need to accomplish is to search for all files which contains "img=" in its content (not filename containing "img") I don't want to do this manually of course (opening and checking files one by one). How I can do this faster.
