Smells like linq here... or what?
UPDATE: By saying fastest way, i mean the Fastest execution time.

View 3 RepliesThe code below displays a thumbnail of each image in a specific server directory and when I click on the image it pops up a nice full sized picture. It works perfectly.
I would however, like to be able to delete an image. I first thought I could have a button at the bottom of the page with a checkbox next to each image, giving it a uniqueID as per the filename but as they are dynamically created I couldn't figure how to handle the Click Event on the button for a randomly named Checkbox ID. Then I tried adding a button next to each item and then tried an OnClick & OnServerClick to call a Sub but this didn't work either.

I am going to need to create a windows form for work that we can connect to a database table, select a directory and move files from the directory that are in the table and move to another folder. The directory will have sub directories that I need to search for the file name and move. I would like to have the table hold the file name (or path) and move all files that are in the database. There might be 20 files or 1000. Depends on the client we are processing for.

I have a SQL Server table with a list of files (path + filename), and a folder with multiple layers and files in each layer. I'm looking for a way to reconcile the two without having to process the list twice. Currently, I'm doing this:
For Each f as FileInfo In FileListFromDatabase
If f.Exists is False, mark it as deleted in the database
Next
[Code]....
Is there a better way to do this? I'd like to avoid converting all the matching files (of which most will be) to FileInfo objects twice. Since I'm a T-SQL developer first, I'm picturing something like an OUTER JOIN of the two lists where they don't match. Something LINQ-ish?

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?

View 9 RepliesI 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.

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:

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.

Why are my new (moved to) text files deleting after the move?
If TextBox1.Text = "* DISPLAY SCROLL 10 *" Then
Dim D10A As StreamReader = File.OpenText("LINE 3 UNITS.txt")
D10A.Close()
[code]....
the file "line 3 units.txt" contains 3 choices. what I need to do is write one of these selections to the new file "line 3 units new.txt" then recognize the contents of this file to control a boolean statement.
Dim W As String = (D10B)
If W.ToLower.Contains("load") Then
LIN3LD = True
[code]....
I end up with 2 known problems.
1) The new text files delete
2) if the file doesn't delete (for whatever reason) the CONTAIN statement doesn't recognize either "load" or "speed"
