File Overwrite - Downloading The Updated Version Of The File Running
Nov 8, 2010I 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 The problem I am getting though, is when the version is outdated, the file will go to download the new .exe and it gets and error saying "File already exists"

Overwrite A Specific File?
Jan 16, 2011I 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.

View 2 RepliesLocked File When Compiling ?
Oct 25, 2010I have been using VB2005 for many years on 2 PCs. Over the last month I have been getting an error when I try to run the project from the IDE:
Error 1 Unable to copy file "objx86DebugBackup.exe" to "binx86DebugBackup.exe". The process cannot access the file 'binx86DebugBackup.exe' because it is being used by another process.
C:WindowsMicrosoft.NETFrameworkv2.0.50727Microsoft.Common.targets 2324 9 Backup
My questions:
1. What has changed?
2. One thread I found suggested that it is a bug, but if true is this something that has been introduced recently (I'm not aware up updating VB2005 unless it happened as part of the general updates).
3. How do I get it back to where it was?
The file is actually locked by my own process, no other application can be using it. I've even tried it with a few line noddy program. I always have to come right out of the IDE, wait a couple of minutes and then go back in - a total productivity killer.

View 1 Replies.net - Overwrite A File That Is Currently Opened By Another User
May 4, 2011I 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.

View 1 RepliesOverwrite /update A File That Is Currently Being Served By IIS?
Feb 21, 2012My 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]...

View 1 RepliesOverwrite A File Using A Buffered Filestream?
May 19, 2012Here'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.

System.Exception: Transaction (Process ID xx) was deadlocked on lock resources with another process and has been chosen as the deadlock victim.
I suspect this
Dim webc As New WebClient
webc.DownloadFile(remotexml, targetxml)

Then i am using the targetxml right after that:
Dim xmldoc As New XmlDocument
xmldoc.Load(targetxml)

It seems that xml file is locked by the first process (WebClient).

.net - Exclusive Access To Text File, To Read And Overwrite It?
Oct 20, 2010I'd like to open a text file and not allow any other processes to write to it. I understand I can do this with the following FileStream:Dim fs As New FileStream(_FilePath, FileMode.Open, FileAccess.ReadWrite, FileShare.Read)
Once I have access like this I need to read all of the lines (I will use a StreamReader(fs)) and then I will need to write to the file (I will use a StreamWriter(fs)).
The problem here is that the StreamWriter won't allow me to set the append mode to false (so I can overwrite all text in the file) when I use the filestream as a parameter instead of the file path. So all text written with the StreamWriter is appended onto the text which I don't want. If I use a StreamWriter with the file path (which will let me set append to false) as the parameter instead of the filestream it will be locked out because of the FileStream FileShare. How can I still have exclusive access to read and write to the file but still be able to overwrite the existing text (append mode false)?
