Compressing Multiple Sub Folders?
Oct 26, 2011
I've written a backup utility for one of our applications; this process involves coping sub directories of a specified base folder and an unknown number of folders within folders. I've got the process down to copy the files and directories pretty easily but I want to compress the folder structure to keep the space needed as small as possible.I've found a few utilities that work well for getting the files from the specified base folder but not any of the folders that exist in the specified start directory.The one utility I found required me to recursively search directories for the variably named directories and I am hoping for a simple switch that can be used that says base folder/file and sub directories.

How do you do it? I've looked it up everywhere and failed to find anything. If there is a previous post I missed that discussed this, post it as a comment and forgive me. <scenerio>Friend and I are working on a VB project. We want to export and inport folders of information, and to do so neatly, we wanted to compress the files in the format we made for our program, then be able to decompress it within the program as well. If theres any other way to do this without compression and decompression

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

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.)

I have built a com object in vb with the "Make Assembly COM Visible" that I use from the strange dialect, "Clarioneese." I maintain 2 versions of our main software, so I have 2 folders, one for each version.My COM object works from one of the folders, but not the other. I copied the exposed dll into both. I used regasm on the copy in the nonworking folder, but still, my Clarioneese programs can only work it if run from one folder, and not the other.Working Folder: C:cs46exe (I didn't name this, don't blame it on me)Non working folder: C:cssqlsdkv6 (I inherited this awful folder structure)If I move an exe built by Clarion into the cs46exe folder, the dll works, but not in the v6 folder.I thought I understood how this works, but I guess not. You can't be successful at this unless you're at least 1/2 a bubble off level.

Here is my need for a windows form program. I have a program that creates .xml files with the same name but on different dates. It is broken down by Type/Date/Time/file.xml. The "file.xml" is the same name every time.
What i need is to grab all of these xml files and export them to excel by pulling certain information out of them.
coding for searching through a windows file structure to pull these files out.
There will be something like 30-40 of these files spread throughout different "Type", "Date" and "Time"

I recently designed a web application using VB.Net and tried to copy a folder (containing multiple files) from one disk drive to another but unfortunately I didn't succeed.I tried using a file upload but that is only for single/multiple file selection however I want to select a complete folder instead of multiple files.

I have a directory structure as follows;
ad_folder
--folderA
--folderB
--folderC[code]....
at I do not know the number of or the names of the folders, they can be different in different cases, I only have the root path.how I can display folder contents in VB.net and the code worked but couldn't figure out how to create the arrays and display only folders within folders starting with "ad_".
System.IO.DirectoryInfo and System.IO.FileInfo to be used for getting the folders.A literal control can be used to create javascript arrays in ASP.NET. These js arrays can then be used on the client side.

I'm currently making a program in Visual Basic 2010 for my Course work, and I'm struggling a little as it involves a "log-in system."
The system will save the Users Information in a folder (Called UserInfo.txt) (Address, Password, Email etc..), and the folder name being the username of the User.
When an Admin wants to view or edit a User, I want the Admin to be able to select the User from a drop-down list and when selected, the information of the user loads in and is displayed in the text boxes bellow (on the same form). The Information can then be edited and Saved back to the file of that user selected with a "Save" button.

A couple of questions about the FolderBrowserDialog in VB .NET Express 2005...
1. How can I make it so this control allows selection of multiple folders at a time?
2. It remembers the folder I selected last time (in the same session), and highlights that folder, which is good, but that selected folder appears near the bottom of the window. Is there a way to make it so the previously selected folder appears in the middle of the window (i.e. the scroll bar is further down the window)? See screen shot attached for how it currently looks when the window opens.

I have a list of directories that get files added to by other users on my network.I would like a script (triggered by scheduled task) that would detect if there are files in these folders older than 15 minutes, and send me an email. I am able to run Batch/DOS, Python, Perl, or VBS - I have them all installed on the server. As long as they can be triggered from Scheduled task.
Example:
C:UsersFTPJoeSFromCustomer <files dropped here>
C:UsersFTPMarkFromCustomer <files dropped here>
C:UsersFTPRobbieFromCustomer <files dropped here>
C:UsersFTPTammyFromCustomer <files dropped here>

(Currently using VB.NET 2010 Express) I'm trying to make a program, the main of which is file transfer. I'm trying to create a program that will keep files and folders synchronized across multiple client computers. I'm using a File system watcher to trigger events, and Using a simple System.Net.Sockets UDP client transfer (found via google) to transfer commands between it and itself on other computers.
Here's that code (this just sends from one textbox to another over the internet)
Imports System.Net.Sockets
Imports System.Net
Imports System.Text
Dim udpClient As New UdpClient(1024)
Dim RemoteIpEndPoint As New IPEndPoint(IPAddress.Any, 0)
[Code] .....
By this method, I can rename, move, or delete files. I want to implement file transfer, so that whenever a new file is created, or updated, my program will automatically transfer the file to the other computers and update them there.

I am developing an application where the user saves a chosen RTF file to a SQL Server database. My problem is that if the file contains an image, the binary becomes too big. Although the database has enough space, it's not very nice to use up space you could save....To give an example:
RTF binary with two text lines ("ABC / efg") = 156 Bytes
Same 2 lines + 32 kB image = 2.2MB
I am still confused on which is the best way to solve this. I have thought about creating an "images" table in my database and using a markup to fetch the image when the file is loaded.

I agree that the best way to shorten the ViewState is to disable it on the ASP.Net controls that don't need it. Keeping it small from the beginning is a great habit.I have also heard that it is already compressed (although can be true... there are ways of compressing it even more, has described in this Stack Overflow question).
My question here is not if it should be compressed... is: when should ViewState be compressed?If we have a ViewState of 410 characters it will weight 410 bytes in a page, while a ViewState of 13.843 characters equals 13.5 KB.
13.5KB is a considerable weight already. And if I compress a CSS file that height 10KB, I think it is also worthy compressing a ViewState of 13.5KB, even if that means a little extra "thinking" on the server.
But is 410 bytes of ViewState worth the extra processing on the server?At what point is it worth compressing?

I've downloaded ZLIB.NET from here and the example VB.NET code they provide works fine. It's very short so I'll paste it here for reference:
vb
Public Shared Sub CopyStream(ByRef input As System.IO.Stream, ByRef output As System.IO.Stream)
Dim num1 As Integer
[Code]...
Note that the CopyStream() subroutine is identical. The problem is that although decompressing seems to work fine, compressing does not. If I take a byte stream, compress it and then decompress it using the above code, I get a truncated version of the original stream (as an example, a 360485 byte stream becomes 311518 bytes). The resulting bytes match the original stream up until the point where it's cut off.
The only information I can find about streams being truncated is due to missing stream.Flush() commands but the output stream is flushed in the CopyStream() subroutine.

compressing sql server data (on the fly) from a select statement when accessed across the internet. i.e data is stored in Sql Server Express on a remote computer (1) connected via an Internet VPN. An application on a remote computer (2) on the same VPN sends a select statement to the SQL server machine.The data would then be compressed at computer (1) sent across the VPN and decompressed at computer (2)
The Reason is, broadband speeds are not the greatest in Australia, and it would reduce the size of the data transmitted, resulting in faster response, as the compression/decompression is done at each machine

I have seen lots of examples with a treeview to list folders then display the folders context in a listview.
But what id like is a checked treeview, that not only displays the folder list, but the actually folder contents as well.

I need help with file enumeration. I'm trying to create a program that can list files, folders and sub folders locations in a log file for diagnostic purposes. After it searches it can open notepad and display the results. The problem I'm having is that I'm a beginner and not familiar with file enumeration.

In my contact manager program I have been storing information by reading and writing comma delimited files for each individual contact, and storing notes in a file for each note, and I'm wondering how I could go about shrinking them all into one file effectively. I have attempted using data entry tools in the visual studio toolbox and template class, though I have never quite figured out how to use them. What would be especially convenient is if I could store data as data type IOwner (a class I created) as opposed to strings.
I'd also need to figure out how to tell the program what to do when a file is opened (I've noticed in the properties how to associate a file type with the program though am not sure how to tell it what to do when it's opened).
Edit:
How about rephrasing the question: I have a class IContact with various properties some of them being lists of other class objects. I have a public list of IContact. Can I write Contacts as List(Of IContact) to a file as opposed to a bunch of strings?
Second part of the question: I have associated .cms files with my program. But if a user opens the file, what code should the program run through in an attempt to deal with the file? This file is going to contain data that the program needs to read, how do I tell it to read a file when the program is opened vicariously because the file was opened?

I am need of creating a windows executable that contains a compression of certain other binary files, (executables etc)
It is a basic form with a button, on press of the button, it has to decompress certain binary files( some other executables too) into a certain path, the decompression happens based on some specific conditions and not always., This is the reason I could not use WinZIP to create the EXE.
