Sep 11, 2008I'd like to use WinRAR's dll file to compress files in vb.net.Is there any way this can be done? The only one I found was using the unrar.dll to uncompress files. Also, I'd like to know how to implement WinZIP's dlls to compress files as the zipfldr.dll does not achieve very high levels of compression and encryption.

Compressing RTF For Database?
Aug 22, 2011I 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.
C# - Worth Compressing The ViewState?
Nov 16, 2010I 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?
CGZIPLibrary.dll Not Compressing Files?

View 1 RepliesCompressing A Stream Rather Than A File?
Apr 3, 2010I'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 Multiple Sub Folders?
Oct 26, 2011I'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.
View 1 RepliesCompressing Sql Server Data Across Vpn?
Aug 16, 2009compressing 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
Compressing A Database To A Single File?
Jun 4, 2010In 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?

View 2 RepliesVS 2005 - Compressing A Dataset Converted To XML Using The GZipStream Class Added In 2.0
Mar 25, 2009I am compressing a dataset converted to XML using the GZipStream class added in 2.0. There are a few things bothering me about this. Here's the code I am using to decompress the XML file:
Using inFile As New System.IO.FileStream(flnm, IO.FileMode.Open, IO.FileAccess.Read, IO.FileShare.Read)
Dim zStrm As New System.IO.Compression.GZipStream(inFile, IO.Compression.CompressionMode.Decompress)
Dim buff(999) As Byte
[CODE]...
This seems inordinately awkward, as I am taking the stream, reading it out into byte buffers, then writing those byte buffers to a memory stream that is then passed to the dataset.ReadXml() method. The reason for this seems to have to do with what is happening in the line colored red. That line is adding a closing > onto the end of the stream. Without that, ReadXml complains about an unclosed dataset. I found out that the > was missing by writing the stream into a string and pasting the string into WordPad. Without that missing >, it appears that I wouldn't need to be using that memory stream at all, and could simply pass in the GZipStream to ReadXML, but as far as I can tell, it's impossible to look at the GZipStream to be sure that the > is not there, and it may be impossible to add it (I haven't tried).
So why is the > missing? Here's the code used to create the file that is being read into the filestream in the above
VB Using ms As New System.IO.FileStream(flnm, IO.FileMode.OpenOrCreate, IO.FileAccess.Write, IO.FileShare.Write)
Dim zStrm As New System.IO.Compression.GZipStream(ms, IO.Compression.CompressionMode.Compress)
ds.WriteXml(zStrm, XmlWriteMode.WriteSchema)
End Using
The real kicker to all of this is that while I was dissecting the first chunk of code, I added a line to check for cnt<1000. My intention was to see the last buffer that was being written into the memory stream to see whether the final > was actually there, or not. To my surprise, I reached the cnt<1000 twice. That means that one read did not read a full 1000 bytes, but read only 675. The next three or four reads were a full 1000 bytes, then the final read was just a few hundred bytes. It is my understanding that Read will return a full buffer if there are that many bytes left to read, and there were, so why did it return only a partial buffer? That suggests that there might be a hole in my XML, though with a half meg file, it's a bit much to read through it looking for something missing. However, the XML that was returned was turned into a dataset that I then merged into some existing data using code that has been working with uncompressed XML files, and I got an error that I should never have received. That may indicate that the XML was, in fact, missing something, though I will have to study the matter further to figure out whether or not that is the case. My major question has to do with the missing '>' at the very end of the file.

View 6 RepliesCommand Line Strings - Make The Program Close If The -1 String Is Sent With The Program
Feb 25, 2010If e.CommandLine.Count > 0 Then
Dim IncomingCommand As String = e.CommandLine.Item(0).ToString
If IncomingCommand.Substring(0, 2) = "-1" Then
form1.close()
End If
End If
I am trying to make the program close if the -1 string is sent with the program. See my installer allows for me to run certain programs before it actually installs, but it doesn't shut down copies of the program itself. So I have a next startup instance set to shut the program down if the -1 is received. But if the program is not running it starts up instead. This is not desired. form1.close doesn't work. e.cancel = true doesn't work, etc etc. What can I do to make the program not start during this instance.
