VS 2008 - Possible To Rename / Overwrite Temp Image File?
Nov 10, 2010
Right now I upload a temp image file, delete the original, and then rename the temp to the original. Is there any way to rename without deleting first? I am doing this in a loop for a webcam program and when I delete the image, it shows a broken image if it is being veiwed right then. I wish I could allow it to overwrite when calling the rename. FYI, I have to upload a temp image first because if I upload the original, it will show as a broken image or partial at timed when being viewed.

Am trying to copy contents of file temp.fxl to temp.seq. I want them to look exactly them. I don't want to copy the file though. I use the following code
Dim fs As New FileStream("c:\fxlate\output\temp.fxl", FileMode.Open, FileAccess.Read)
Dim s As New StreamReader(fs)
[Code].....
With such simple code, the last line in temp.seq is truncated as attached and the size of the file is smaller than temp.fxl. See attached files. What do I need to do on the above code. Is VB.NET failing to write 1024 characters on one line.

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?

I am helping a friend convert files from floppy to CD. The files are in WordPerfect for DOS (8.3)format. she named the files as follows: name.month eg; Baker.jan. if there were more than 1 "Baker" files in the same month she named them baker1.jan,Baker2.jan etc... She then copied them to floppies and when one got full she started another. The problem is I have multiple instances of the same filename on different disks so when I copy to my HD windows asks if I want to overwrite the files. I have been writing the names down and renaming them manually. Is there any way to automate this process? I would need to perform the following:
1. Check if floppy filename exists on HD already
2. if it doesn't, copy to HD
3. if it does, is it the same file or different file with the same name (file size has been a good indicator so far)
4.If it's the same =>ignore and go to next file on disk
5. if different, rename then copy to HD then go to next file
6. repeat until all files have been copied
I have 300+ disks to do this with and it is very time consuming.

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 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)

The following code for installing log messages has worked on Windows 7 and XP, until I came across an XP machine where someone had deleted the Temp file under Documents and Settings/ComputerName/. Is there a safer location to install a log file?Path.GetTempPath doesn't seem to be the best idea.
Public Sub appendLog(ByVal message As [String])
Dim format As String = "MM/dd/yyyy HH:mm:ss.fff"
System.IO.File.AppendAllText(System.IO.Path. Combine(System.IO.Path.GetTempPath
, "Log.txt"), vbLf + " " + DateTime.Now.ToString(format, CultureInfo.InvariantCulture) + " " + message)

I am trying to create an MDB as a temp file to save some tables and query them. After creating, I can't delete it ... Even before it is actually used. The process cannot access the file because it is being used by another process.
Dim mdbFileName As String = System.IO.Path.GetTempFileName
Dim objClassType As Type = Type.GetTypeFromProgID("ADOX.Catalog")
Dim obj As Object = Activator.CreateInstance(objClassType)
obj.[GetType]().InvokeMember("Create", System.Reflection.BindingFlags.InvokeMethod, Nothing, obj, New Object() {"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & mdbFileName & ";"})
[Code] .....
This MDB (after all operations) is huge (+200 Mb) and needs to be deleted.
