View 3 RepliesI 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)
View 4 RepliesI have been working on a project in .net. I can now write to a txt file using [code]What I need to do though is instead of writing new lines to the file is replace what is all ready there with new text.
View 1 RepliesHow 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.
I'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)?
I cant seem to figure out how to add text to a text file without overitting all of it. I am using:
Code:
File.WriteAllText
I guess I could read it, copy, and then write it all over. Is there a way to just add text to the end of the current text of a text file?
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

I have spent the past week trying to get my copy of Visual Studio 2010 Professional to work on my Windows 7 Professional 64-bit laptop, with no avail.
Every time I try to create a new form using Visual Basic, an error message saying that Microsoft Resource File To COFF Object Conversion Utility has stopped working, and I cannot even run the new form to see if my coding is correct.
I have managed to find that it has something to do with the cvtres.exe file, but after a solid hour of research, I have found numerous others with a similar problem, but no solutions.
I have done registry scans, reinstalled Visual Studio about 3 times and have done many other suggested fixes that have done nothing but waste my time.
This is the very first time I join this forum, since I have difficult convert vb.net code into windows mobile 6.x vb.net compact frame. I hope someone know how to write coding for compact frame.

I have this Quiz software that lets you create online multiple choice quizzes which are great for studying (I am in grad school and I'm trying to use everything I can to learn). So the Quiz software is great but it only lets you input questions by hand, one by one. I took a look at the .xml file that the quiz program spits out and came up with the idea to try and make a converter so that I can import many questions at once. I was hoping to try and solve this limitation by doing the following:
Take a .doc that say a tutor gives us with a bunch of practice questions, and then take that into Crimson Editor, and then format it so the question is on line 1, the multiple choice answers are on lines 3,4,5, and 6, (for the next question, the question would be on line 11, and the answers on lines 13, 14, 15, and 16, and so on) and then take that saved .txt file into my program, hit the generate button, and it will spit out the .xml file, and then import that into the quiz software to generate the online quiz.
Here is an attached screenshot of my program layout so far:
I figured out how to open a text file by watching simple youtube tutorials, but I don't know how to have it generate the stuff and have it show up in the bottom text box. I know how to do the coding to convert the txt to proper xml code but I don't know how to be able to save the contents of the bottom text window to an xml file.
I'm trying to get a save file dialogue to overwrite a file with the same name.

I am reading a temperature value from a transceiver into the serial port and I want this value to change the value of a label in my Visual Basic Form. This value changes every few seconds. I am using the code below:
Me.dataReceived.Text &= [text]
where dataReceived is the label I am using and [text] is the data I am reading from the serial port. This results in the data being displayed but instead of overwriting the label, it writes the value after each other. (The data is appended). I tried to remove the & before the = but this did not work as nothing showed up.?The code I am using is the following:
'To receive data into the text field
Private Sub SerialPort1_DataReceived(ByVal sender As Object, ByVal e As System.IO.Ports.SerialDataReceivedEventArgs) Handles SerialPort1.DataReceived

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.

FileToCopy = "C:\test.txt"
NewCopy = "C:\NewTest.txt"

View 8 RepliesI 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 RepliesMy 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]...
I am wondering how I can replace a file locked by another application. I am using VB.NET from 2008.

View 1 RepliesHere'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.
