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.

Dim a() As Byte = {}
FileGet(1, a)

View 1 RepliesI have File Like "Sample.bak" and when I compress it to be "Sample.zip" I lose the file extension inside the zip file I meann when I open the compressed file I find "Sample" without any extension.

System.IO.File.WriteAllBytes(destination & name & ".Bak" & ".zip", compressed)

View 3 RepliesIs it possible (I'm sure it is) to validate a user's credentials against Active Directory without using Directory Services?I'm building a Browser-Based WPF application which requires users to login to and get validated via Active Directory. Since .Net 4.0 (or maybe 3.5) accessing Directory Services from an Application requires the application to be fully trusted. Since IE won't provide full trust to an application if it doesn't have the signing certificate in it's cert store, the application is refused startup permission.
If I don't use Directory Services, then I can leave the application as Partial Trust and validate my user's credentials without having to install a certificate on each user's machine.

View 13 RepliesI have a straight-forward task I'm attempting to accomplish. I have the mechanics down, and need to hammer out the details but I'm stumbling across one small point. :)
This script is supposed to take the files in the local C:Temp directory, and copy them to a selected user's shared directory on the file server.
Protected Sub btnCopy_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnCopy.Click
My.Computer.FileSystem.CopyDirectory("C:Temp", "\MAVERICKVOL1Users" & ddlName.SelectedValue & "DESKTOPRECORDINGS", True)
End Sub
This script does indeed work (and I'm aware I need to create exception handling) but it only copies what contents are on the server's directory of C:Temp rather than the local source directory.
I'm using VB.NET/ASP.NET to achieve this.
How am I able to direct my function to use the local user's directory rather than the remote server?
I am attempting to compare two directory trees. I have the program map the network drive and copy a directory.

View 1 RepliesI am going to need to create a windows form for work that we can connect to a database table, select a directory and move files from the directory that are in the table and move to another folder. The directory will have sub directories that I need to search for the file name and move. I would like to have the table hold the file name (or path) and move all files that are in the database. There might be 20 files or 1000. Depends on the client we are processing for.

Also, on a slightly different topic (I didnt think it was worth starting a new thread for it), I need a program to start during the start up of the computer it is on, am I right in saying I need to create a shortcut (which I think is a .lnk file?) and then put that in the startup folder. I'm doing this in code, but I was wondering what information I need in the shortcut file.
