Close A File In .net?
Feb 15, 2011
I have created a windows service that update a database(FOXPRO->MYSQL) every one hour. I fill the database from foxpro into a dataset and then write an xml file then load it to mysql database. It is a success every start of a service, the problem is every next run I am receiving an error --> The process cannot access the file 'D:\CivilStatus.xml' because it is being used by another process. To resolve this problem I stop the service and then restart again manually. What I want is the service will automatically run every an hour without restarting it manually. Here is the part of my code:
Dim XMLFilePath As String = "D:\CivilStatus.xml" 'Path of my xml document
If File.Exists(XMLFilePath) Then
My.Computer.FileSystem.DeleteFile("D:\CivilStatus.xml")
[code]....

I'm currently in the process of building a text editor type program, and have run into a brick wall. I haven't done VB in years, so I may just need a little reminder on some things. I have coded everything so far as far as opening files, saving them, changing fonts, colors, etc. However, I'm looking to add a Close button to my menu strip that will just close the currently opened file, and not the entire program, while also ask the user if he/she would like to save before closing the file, and then if they select yes, it will show the save dialog, and if not, it will go ahead and close the currently opened item.

In my code I have
IO.File.Create("C: ext.txt")
then I try to
IO.File.Delete("C: ext.txt")
How do I close the file that was created?
I have done something like this for writing to files but not creating files.
Dim infile As IO.StreamReader = IO.File.OpenText(path)
infile.close()

I have created a CMS-system and I am using it on different homepages. To manage updates quick and easy I made a administration-system for uploading the updates on all homepages on the same time. As long as I only have to overwrite the old files everything is going fine, but there are some few files on every homepage containing some different constants.
For that purpose I made this code:
Open the new file to be copied from my default cms-system:
Dim fs as new FileStream("D:WEBLOCALUSERmysite.dkskabelondefault.aspx",FileMode.OpenOrCreate)
Dim objReader as new StreamReader(fs)
Dim strFile as string = objReader.ReadToEnd
objReader.close()
[Code] .....
Sometimes first file is updated successfully, but for the next file I got this error:'D:WEBLOCALUSERmysite.dkskabelonempdefault.aspx' because it is being used by another process. I tried to close and dispose everything possible, but still the file is in use for minutes.

In a program I'm working on, I want a "Loading..." dialog to close when it can't log in to a site using the username and password provided by the user. Basically, I have the code set up right because the function it is supposed to carry out when that occurs does work, but for some reason it ends up in some really weird stuff happening. In the Loading form, I have it set to do "Form1.Show()" and then "Me.Close()", assuming it would simply show the login form and then close the Loading form. However, when this happens, the Loading form closes, and then for only an instant Form1 shows, and then the Loading form shows and Form1 closes. This happens forever until I stop the debugging, and I can't seem to figure out why. Am I using the wrong method? What exactly does Me.Close() do anyways? All I want to do is close the form and open another

I should mention that I'm mainly concerned with Random files.Which is the best method?
1.) Open file, manipulate data and immediatly close the file. (Which means doing this alot everytime data needs to be read, edited, deleted, or saved)
(2.) Open the file when the app starts and let it open for data manipulation until it's time to close the app at which time the file would be closed.
I was always taught option 1. The main reason at the time was to cut down on the chance for data corruption in the file or an outright loss of the file due to outside circumstances like power failure.

Dim XLApp As New Application
Dim WkBook As Workbook = XLApp.Workbooks.Open("C:Book1.xls")
Dim Sheet As Worksheet = CType(WkBook.Sheets(1), Worksheet)

Its been requested that my project has a way to limit number of users logged in at one time. I have that figured out but there is a problem. What I have done is that when a user logins in the application creates a .usr file in a directory on the network. If the number of users (value in the database) is less than the number of .usr files another user can log in, otherwise they can not(the file gets deleted at logout or application close). Now the problem is I need to create a way that if the .usr file get deleted the application will close. Is there a way to keep a watch on file and if it gets removed close the application.

sometimes, when I use Form.close() when debugging my program, although the form is closed, the application is still running. I noticed this behaviour when using the msgbox function.

1. I'm not sure if this goes here or on the ASP board, as it's a hybrid of both. If this is the wrong place I apologize in advance.
2. It's my understanding that this isn't a problem in IE7, but my company is on IE6 with no current plans to upgrade.
So I have some code running client-side via 3rd party software. It opens an IE window and shoots a request to a server-side ASP page like this[code]...
I've tried using Javascript to close the browser, but I can't reset the ContentType. I tried CloseMainWindow after I call the ASP page, but that threw all sorts of errors. I imagine I could use a timer but the process varies from a few seconds to five minutes.

Okay in my program I have users select options and then it writes text to a file. When the user restarts the program, I want it to read from the file and search for specific text like "User is a senior,False." At this point if the file has this text, I would like the program to read from a line in the program.
