File Overwrite - Downloading The Updated Version Of The File Running
Nov 8, 2010
I am trying to download a file off my web server (easy) but the file its downloading is the updated version of the file running. I finally was able to program my automatic update software the program simply downloads a .txt file from my web server, reads it, and if the the version = (new version here) then download. If not, then go to another form. The problem I am getting though, is when the version is outdated, the file will go to download the new .exe and it gets and error saying "File already exists"

I'm with a big problem here. I have a 1.0.0 application that installs an Access Database into the user's machine. I have also a 1.0.1 version that needs to be released, and it has an new database file that i want to be installed overwriting the old file. Unfortunately, if the user does any update to the old file, the 1.0.1 version does not overwrite it anymore, and i did not find in any place how to force this file to be deleted or overwrited after being updated.

I would like my program to overwrite its previous version such that users don't have to uninstall the previous version before installing the new one.
I'm guessing it has something to do with setting Publish Version (Major, Minor, Build, Revision), Assembly Version or File Version.

I'm trying to get a save file dialogue to overwrite a file with the same name.
Private Sub Button6_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button6.Click
If RadioButton16.Checked Then

I keep getting an error saying "Unhandled exception has occurred in your application." Then the next paragraph says "The process cannot access the file 'E:Copy of Release+Fontsob.txt' because it is being used by another process."

How they relate and differ from each? What are the best practices for version control? Is there a primer about publish online? Or a good book?
And is it possible to make ClickOnce and a msi in one solution of VS 2008? If so, is there any conflict or pitfall?
BTW I am using VB if that makes any difference.

How can I save an Excel-file, which I'd edit with VB.NE, to a file, which already exists? Evertime there is a dialog: File already exists. Do you really want to overwrite? YES|NO|Abort
How can I overwrite without this dialog?

In this link there is a text file [URL] . However, using this code, it downloads an empty file. Why ? [vs.net 2005]
Dim Url As String = "http://stooq.com/q/d/l/?s=gc.f&d1=20110602&d2=20120531&i=d" Dim myWebClient As New WebClient() myWebClient.DownloadFile(Url, "c:file.txt")

KB Article Q180366 has a good (and really simple) solution on how to detect when a web page is done loading. However, it is horribly out of date (applies to IE 4.0). Has Microsoft produced an updated version to this solution that works with more recent version of IE like IE 8? Here is the older link: [URL] Seems like everyone has a solution that works sometimes but not one that works all the time.

I am trying to get a text file to be overwritten since it's already there. The thing is, that I'm not trying to overwrite a specific file. In fact, EVERYTHING must have the right name, or my project won't turn out right: http:[url]....However I don't have that problem any more because I solved it. Now my problem is much more simple. Again, I'm NOT trying to overwrite one specific file, so I couldn't say something like,
HTML
RmDir("C:KQQuestion1")
I need a way to overwrite any file name.

I have a couple of files which I have to update periodically through a process written in VB.net . These files are on a server and part of a domain that many users can access. These files should never be written to as they are for reference only. I need to be able to overwrite some of them even if a user has them opened. Is it possible to do this? Presently the files permissions are not set as read-only but I can do this as long as the user under which the process runs will still have permission to overwrite them.
UPDATE: thx for your responses. The files are pdf and are opened by clicking on them from windows file explorer. This also happens when a user simply has the file selected in windows explorer.

My company puts out a monthly newsletter which I host on our internal website. I have a page for the author of the newsletter to upload the latest version. Once the author has uploaded the latest newsletter, he sends a broadcast email to announce the new newsletter. Employees invariably check the new newsletter and send feedback to the author with corrections that need to be made.
Once the author has made the necessary corrections (typically within an hour of sending the broadcast email), he revisits my page and replaces the latest version with the updated newsletter.
Immediately following the replacement (or update, if you will) of the newsletter, anyone attempting to access it gets a 500 - Internal Server Error.
My IT guy who maintains the server cannot delete/rename/move the file because of a permissions error and has to do a lot of convoluted things to get the file deleted (and once the file is deleted, the author of the newsletter can re-upload the corrected copy and it works fine.
My IT guy and I are pretty sure that the problem stems from that I'm trying to replace the file while IIS is actively serving it to users (which I thought of and thought that I had coded against happening).[code]...

Here's the catch - for the program I'm making I would like to avoid creating a copy of the file in its totally unencrypted state (I'm using a modified, quick-and-dirty XOR cipher for that. It's secure enough for my purposes and faster than the stronger encryption). Anyhow, what I would like to do is read a block of data, de/encrypt it (in memory) and then write the changed bytes to the same location they previously would have been within the file.
I've found the problem a little outside my programming abilities, so I was wondering if anybody had a pre-made solution, links to appropriate examples, or an all out explanation.

I have a log file that is open and in use by another program, and I read it's contents with the following:[code]This works for reading the text from the file while it is still in use by the other program, however, immediately after this I need to truncate the text file (without deleting it) so that it is blank again. But the file will still be in use by the other program.[code]But I get the "in use by another application" exception. I've tried looking in StackOverflow and googling but I can't seem to find an answer, and I can't find a way to do this with filestreams either, or I would try to use Dim fs As New FileStream(FullPath, FileMode.Open, FileAccess.Write, FileShare.ReadWrite)

How to read from a line in vb .net, I need to do the following:
change the line in a text file
[Path] = "c: hiscertainpath"
With this line
[Path] = "c: hatother
ewerpath"
These paths will most certainly be different lengths, so I need to either replace what's in the quotes or erase the line completely and enter a new one, but in the same spot, not appended to the end of the document.

Let's say I'm trying to have a program that will check for a version.txt file online, and enable the user to download a new version of my .exe.Here is an example of how i get the new version. I apologize for the old syntax, but i just got out of VB6 and am still learning FileStream, etc. Inetconnection is just a function similar to Webclient.DownloadData.
DABytes = InetConnection(Pathy)
Targetfolder = Application.StartupPath & "DA.exe"
foldera = FreeFile()
