Checking Multiple Files At Once?

Jun 14, 2012

Making a system to check for files existing in a network (for our tv address system, pawn shop stuff)Anyway, the command1 checks if d1.txt exists, then d2.txt and fills out the boxes, Instead of 10000 if statements?

Below is example of my current code

Private Sub Command1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Command1.Click
If My.Computer.FileSystem.FileExists(Text1.Text + "d1.txt") Then
d1.Checked = True

[code]....

Basically it's a bunch of check boxes, that check if the corrosponding file exists

Checking For The Existance Of 6 Files?

Feb 14, 2009

I have this code for checking if 1 file exists (binPath is already declared):

Dim filename1 As String = "OpenSim.Grid.UserServer.exe"
Dim U As Boolean = System.IO.File.Exists(binPath + filename1)
If U = False Then[code]....

However, I need to check if another five files exist too. Should I just copy the above code another 5 times, or is there a more efficient way of doing it?

.net - Checking If A Specific Files Is Currently Open?

Jun 15, 2012

I was wondering if it was possible to check if the file "test.txt" is open? and if so then display a message that the file is in use? My biggest problem is that the file can be opened in notepad, word, excel etc. I have some basic coding, which checks if the file is open - what I am trying to do is check if the file is currently open and if its not in use then proceed with the coding, I have the following coding so far.

Dim Process() As Process = System.Diagnostics.Process.GetProcessesByName("notepad")
Dim Process2() As Process = System.Diagnostics.Process.GetProcessesByName("word")
For Each p As Process In Process

Checking Multiple Items In A Check List Box By Variable Values?

Synchronizing - (using A Background Worker) Checking All Of The Files & Subfolders

Jul 17, 2009

Unless someone knows of a way to do this already in windows, what's the best method for (using a background worker) checking all of the files & subfolders in a folder against another folder in an external usb hdd?

I'd like it to copy only the files that's changed since the last backup, and it'd be nice if I could right-click on a folder (which i can easily google this one, it's a common thing) and select my program and it'd pop up a window to get the destination (since the source is known from the windows context menu) and only copy (overwriting the existing files/folders) that've changed since the last backup.

Asp.net - Implement Security Trimming With A Website With Multiple Folders And Multiple Web.config Files?

Jun 18, 2012

I have a website that has highly granulised access and hence requires many web.config files. The problem is I would like to trim the menu so that only certain users will have access to certain folders. I have enabled trimming and setup roles in the sitemap, however when I access the page the menu is not show, as I am authorized to view the default page which is not in a subfolder. When I type the url of a page in sub folder's I have access.

How should I handle this:

A site map for each web.config file - don't know how this will work Removing the sub web.config file to only use a single one

Searching Multiple Files In Multiple Sub-folders

Mar 30, 2010

I'm developing an application to help law enforcement retrieve and analyze logs and other files left by the use of Pidgin (a multi-protocol messenger client). Right now I'm nearly done, but I want to add the ability to search chat logs for user-defined words or phrases and I don't even know where to begin.

Chat logs are stored as html documents in a folder/sub-folder/sub-folder/sub-folder fashion, where each sub-folder can have dozens of sub-folders inside of it, and the final sub-folder can have dozens if not hundreds of chat logs. If anybody could point me in the right direction, I'd be very grateful.

(Also, this is the first program I've written since about 2005, and I'm essentially teaching myself VB as I go. If you'd like to see what I've cobbled together so far, you can find the program here.)

Merge Multiple Excel Files Into One Excel File And It Works For 3 Source Files But Its Not Working If Workbook With Worksheet Count Is > 3?

Aug 18, 2011

I'm trying to copy multiple excel source files into one excel file. My current code is working only for 3 source files..If more than 3 files are there, it doesn't copy the data but creates blank work sheet in the output excel file. Lets say I have a source folder with 5 excel files. Each workbook contains one worksheet with data. It copies upto 3 worksheets along with data into output excel file.

Lets say excel1 contains A as work sheet, excel2 contains B as work sheet ,excel3 contains C as work sheet ,excel4 contains D as work sheet ,excel5 contains E as work sheet .Now my output excel file should look like..OutputExcel with A, B, C, D, E along with respective data.But my current code is giving output as A,B,C worksheets along with respective data but its creating blank sheet1,sheet2 in place of D & E.

Checking For Date Overlap Across Multiple Date Range Objects?

Nov 7, 2011

I have several records in a database that have Start and End Dates

09/15/2011 - 09/30/2011
10/15/2011 - 10/22/2011
11/01/2011 - 11/15/2011

When user stores a record, I need to make sure dates don't overlap.My simple code checks date ranges within a specific record (e.g. user enters 9/16/2011 or 10/21/2011, I throw an exception.)But, on the slim chance a user gets creative (e.g. 10/14/2011 - 10/23/2011 or even 10/14/2011 to 11/16/2011), now they have circumvented my check.BTW, the user could enter 10/14/2011 to 10/23/2011 if they were editing the record that contained values 10/15/2011 - 10/22/2011.So, I'm trying to solve this riddle with a linq query. However, what I have isn't working exactly right.

UPDATE Nevermind about code not working. While trying to provide an example to expand on Miika's repsonse, I found my answer. So, giving credit to Miika for pointing me in the right direction and posting my working code below:

Here's my code:

Downloading Multiple Files Specified In TXT Doc?

Aug 18, 2010

I've come up with a way of downloading multiple files specified in a txt doc held on a web server. The problem is it only downloads files not folders, im using the following from the codebank to download the files currently:

Try
mCurrentFile = GetFileName(URL)
Dim WC As New WebClient
WC.DownloadFile(URL, Location)
RaiseEvent FileDownloadComplete()
Return True
Catch ex As Exception
RaiseEvent FileDownloadFailed(ex)

Can I modify this to allow downloading of folders too or will I have to use a completely different method?

FileSystemWatcher - Multiple Zip Files?

Sep 13, 2010

I am in the process of writing a windows service that will be replacing a vbscript that runs via a scheduled task currently. It currently runs on 350 kiosk machines in 350 different locations.Here is what the vbscript currently does:

1. The machine receives a ZIP file in the RECEIVE directory. Configuration_09122010_1234.zip. This file contains software configuration files that need to be copied to specified folders on the machine and to another machine on the local LAN where this kiosk is located.

2. The zip file is extracted to a folder with the same name as the zip file.Inside the zip file is an instruction file (.txt) and files that are referenced in the instruction file.

3. Opens the instruction file and performs the instructions in the file. Example: (this would copy pricingfile1.dbf to \mymachinecapplication1pricing, and then execute softwaresoftwarepatch1.exe which is located in \mymachinecpatches)

pricingfile1.dbf, \mymachinecapplication1pricing, copy
softwarepatch1.exe, \mymachinecpatches, run

4. Once all of the actions in the instructions file are completed, the folder where the zip file was extracted is deleted and the zip file is renamed to configuration_09122010_1234.zip.applied to show that it was processed by the script. Also, because the script is a scheduled task, this ensures that the file is not applied more than 1 time.

So I have started writing the service using the FileSystemWatcher. Basically I look in the receive folder for any file that looks like Configuration_MMddyyyy_*.zip and unzip it to a folder of the same name.

1. I have been doing some reading about the FileSystemWatcher Created event.I read an article about how the Created event fires as soon as the first byte is written but doesn't necessarily mean that the complete file has arrived at the machine. A post I read involved a .csv file and it mentioned that you try to open the file and catch any errors - if you cannot open the file, it hasn't arrived yet. This makes sense to me but I don't know what the equivalent would be to a zip file. It's not the same as opening a txt or csv file.

2. There are times that we send more than 1 configuration file in the same day, or even, at the same time. Above I mentioned the name was Configuration_<date>_1234.zip. The 1234 is a sequence number, always incremented. The idea is for 1234 to be applied before 1235 and 1236. So if I had 2 files sent *at the same time* and I want them to apply in order, how would I do this? I thought about when I am applying 1 file to stop looking for changes until after the apply process is completed, but then I *think* I would miss any file that arrived while I EnableRaisingEvents = false?

How To Compress Multiple Files Into One

Nov 21, 2010

I want to have a backup feature which takes about 7 txt files and compresses/packs them into one file. Then if required at a later stage I can unpack all 7 files from the packed file. I do not need any compression as such just to make one file from 7, then 7 from from that one, if you understand what I mean. I have read there are some native libraries in .NET Framework 2.0 called DeflateStream and GZipStream. Can these be used?
