im having a problem getting free direct linking file hosting for my updater program to work. im currently trying to use google docs for this but it doesnt support .exe files.what im thinking about doing is zipping it and downloading the zip then unpacking it in the code. anyone have an easy way of doing this or an alternate solution to this problem?
View 1 RepliesOnce again, im stuck, ive searched everywher I do not understand at all the zip extraction libraries
Now what im wanting to do is unzip a file mentioned in a texbox and then a directory mentioned in My.Settings.Directory with a progress bar, with a label that changes text, for example: Unpacking, % unpacked or files that are being unpacked.
I want to unzip files from my program, so i'm using the Shell32 functionality like so:
Module Module1
Sub Main()
Dim sc As New Shell32.Shell
Dim srcDir As Shell32.Folder = sc.NameSpace("zippath")
Dim destDir As Shell32.Folder = sc.NameSpace("destinationpath")
Dim items As Shell32.FolderItems = srcDir.Items()
destDir.CopyHere(items, 256)
End Sub
End Module
This theoretically works, but i'm unzipping an 8Gb compressed file and the dialog that pops up says it will be done in 1day, 19hours. This is ridiculous because when I just right click on the file and decompress it from there, it takes only a couple of minutes! I can't imagine what the problem is! I know that the shell process actually spawns its own thread, so I worried at first that my process was exiting before the thread could spawn and added a Thread.Sleep(1000) after destDir.CopyHere() but it had no effect.

View 5 RepliesI need my program to 'take a peek' into a ZIP file and see if it contains a certain file. I need it to do this many times for a large number of files, so I would prefer it without having to unzip the entire zip-file each time, as that would take far too much time (it's a fairly large zip-file of about 250 MB).Also, I don't need the actual file at all. All I need to know is if it exists inside the zip file.
vb.net
If IO.File.Exists("C:FolderIPFile.zipfolder_in_zipfile.jpg") Then
' "file.jpg" exists inside zip-file!

I have a vbscript that does the following but I want to do it in vb .net and was hoping someone could post some sample code to get me started. The script does the following. Monitors 2 folders specified in a config file. When a zip file is put in the one of the folders it us automatically unzipped to a working folder and then the zip file is renamed to unzipped-<zip>.zip. I am hoping someone could post a visual studio project or code that might help me get started.

Having a slight permission problem with Win 7 I am guessing it will be the same on Vista but work fine on XP (yet to try)But my program is sitting in: C:Program FilesCompanyProgram And its trying to create new files alongside itself in the Program Files area but bombing out which I know is permissions. If I go there to create the file myself it comes up with a UAC prompt and when I hit allow it works fine but obv the program can't do that byiteslf so bombs out.Is there anyway I can over come that without the user having to grant admin rights to the program each time it starts or do I have to write data to another place?

View 1 Repliesin the current project im making i've decided to add in some tools, 1 of which is a renamer based of a renamer app that already exists (called scdtoolz), i want to build my own version of it so i can learn some new things, and build a nice GUI version of it.[code]So what i have managed to determine is that the current app scans the folders contents for the CRC32 Checksum, and renames based of that, since the 456.bin's CRC32 Checksum was 2274F80B, and in the text file 2274F80B is found here 'WWF - Rage in the Cage (T-81015)(U)#2274F80B#'So now i have determined game identification is based of the CRC32 checksums, how would i go about coding a similar ap in vb.net?first i need to make the app scan a folder, but how to return crcchecksum? and then rename if check = XXXX? If MD4 sums are easier/simpler i can use those instead, im lookin at a few hash app sources now, so i think i can see how to get the md5 but not the crc32 yet, or how to rename the 2 files and folder based of the text file.
View 6 RepliesI am trying to create an application that will copy files with a "*.1" extension over to another directory and change the file extension to .tif. The problem is that the *.1 files are located within zip files. Is it possible to copy files out of a zip file without having to extract it? The code I have so far is below. I have only gotten to the point to list all *.zip files found in a specific directory in a listbox. I am really looking to list all *.1 files found within all .zip files in a specific directory. Once they are all listed in the listbox, I will then chose a destination directory, copy them to the destination directory and change the files from a .1 extension to a .TIF extension.

I have a question about the performance possible gains of using XML files in a VB.net 2008 windows form application. I am going to pass an XML file for parsing to an embedded resource file or into the release/debug configuration manager (app.config) file to be parsed by the same QuerySectionHandler. For performace wise, is there a preference of using an embedded resource file over the same xml in a config file?

View 13 Repliessaving required files in vb 2008, zipping it, and sending it in to my teacher via emails. When I finish the program, I hit save as and put it in a new folder. I then zip it up using winzip, send it to my teacher through our school website. When she gets it however, she cannot open it and says I don't have all the required files. I can still open it on my computer, though, and don't know what I'm doing wrong. Any advice would be helpful on what else I'm supposed to do. If it helps the program that I am doing I have to get it from a zip file she sends us, re-modify it a little, re-save it, and send it back.

I recently upgraded from vb.net 2003 to vb 2008. I see that when I "Build" the application all of the program files are generated, must like with vb.net 2003. When I use the ClickOnce publish approach, a set of files are generated including the setup.exe. When I double click on the setup file, the program installs deep down in My Documents. If I navigate to that location there is a complete set of my application files along with some Manifest files and a Manifest folder.
I wish to package my program for installation using INNO Setup Compiler, because it is very flexible and allows me to add information and choices through the installation process. My question is - if I package the "Publish" set of files, should I be including the files that are generated and located in the "Manifest" folder? and if so, do these files need to be located in their own folder as was installed on my computer? Or can I simply add them to all of the program files?

View 3 RepliesI've got a client/server communicating nicely using TCP to send text strings and to parse and act upon the messages at either end, but now I want to be able to send small files. I thought it would be as simple as reading the contents of the file into a buffer and sending that buffer as if it was a message but obviously not. When I retrieve the message at the client end I get "System.Byte[]" so its given me the variable type and not the actual contents of the array I thought I'd passed in!
My Sending code is this :
Public Sub SendFile(ByVal Filename As String)
Dim sw As IO.StreamWriter
Dim fs As IO.FileStream

(NB I did search for this within the forum and found some examples but they just didn't fit very well with the framework of what I'm doing, such as creating a 2nd tcp channel to handle file transfers?
I need to upload a file and rename it. I have found a lot of code that uses the WebRequest for this.
