Oct 18, 2011

I have the following unzip function which works fine if I have only 1 zipped folder..However, how can update it to accomodate a zipped folder within a zipped folder.

Code:Private Sub unzip(ByVal filename As String, ByVal targetdir As String, ByVal overwrite As Boolean, Optional ByVal password As String = "")

Dim source() As Byte = System.IO.File.ReadAllBytes(filePath)
Dim compressed() As Byte = ConvertToByteArray(source)
System.IO.File.WriteAllBytes(destination & name & ".Bak" & ".zip", compressed)

Or using this code :

Public Sub cmdCompressFile(ByVal FileName As String)

'Stream object that reads file contents
Dim streamObj As Stream = New StreamReader(FileName).BaseStream

[CODE]...

Explore A File Folder Or Zipped File?

May 6, 2011

When I right click a file folder, I get an option called Explore on my pop-up menu. It lets me do this for zipped records also. I want to be able to do this programmatically in my Visual Basic program. How do I explore a file folder and expose its contents in a Listbox. How can I do this for a zipped file? If a folder is zipped and contains a list of files in it, can I go into the file and delete the file without having to unzip the folder. Today, I was able to cut files out of a zipped file and paste the individual files somewhere else. Can I do this programmatically?

VS 2010 How To Decompress A Zlib-compressed File

Mar 24, 2012

I would like to decompress/compress text files in zlib format.

Here's what I tried:

- Downloaded zlibwipa.dll from [URL] and tried to add a reference to it but got an error saying it is an invalid assembly.

- Downloaded DotZLib from [URL] but can't get it to work, error message: Unable to load DLL 'zlib.DLL': The specified module could not be found. (Exception from HRESULT: 0x8007007E)

- Looked at this [URL] but couldn't do much with it

This files are textfiles created from flash with ActionScript 3.0, but compressed, using the ByteArray class's compress() method. I know Flash uses zlib algorithm for this, and I would like to open and use this file from vb.net.

I am using something like :

FileOpen(1, OpenMapDialog.FileName, OpenMode.Binary, OpenAccess.ReadWrite)
Dim a() As Byte = {}
FileGet(1, a)

[Code]....

Create And Write To A New Text File From An Existing Text File?

Sep 2, 2009

I have a very large text file about 4 million lines that I would like to separate into several small text files based on the strings contained in the first column of the text file. I want to open the large text file, choose the lines that apply, create a new text file with a name that has a number at the end of which will match up with the value in the first column of the text file. I want to then copy the applicable lines to the new small text file, save and close it. I'm not sure how to go about doing this after opening the large text file and using the readline method. What if the folder does not exist? Do we have to create it? I want this procedure to be general, as there could be up to 25 million lines in the text file.

Write Listbox Text To Text File And Keep Columns Aligned?

Apr 16, 2011

I've got a program which displays data in a listbox in five columns. All are separated using one or more ControlChars.Tab. I want to write these columns to a text file, however, when I do, my columns lose their alignment. I can change alignment so that it displays nicely in text file, but then it is off in list box. Is there a way to get what I see in my listbox to display the same way in a text file - maybe a different way of separating my columns (not using ControlChars.Tab)?

File I/O And Registry :: Write A Text File In XP Versus Win7

Sep 28, 2011

I am using Visual Studio 2008 on Windows XP SP3. User has Windows 7 Pro (32 bit). The IO code below works for me. The read code works for user, but the write code only works for new files. If the user tries to overwrite a current data file, then no data is written to disk. I have done all the usual IO checking (valid file name, etc.) and have excluded it from my same code. In my app, FileSave and FileSaveAs both call WriteDataFile(FullFileName). Any reasons why FIleSave would work on Windows XP, but not on Windows 7 Pro (32 bit)?

Code:
Public Function ReadDataFile(ByVal FullFileName As String) As Integer
' reads a Data file from disk
'
' Format is a text file, with [TAB] seperators and [CR][LF] as line terminators
