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'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.

View 3 RepliesI have a form which when button1 is pressed creates and displays a new form. From this form a user has the choice yes or no buttons. Each button has its own handler and script it executes. If yes is clicked i want to run the script and then close both forms. I used me.close() and that only closes the orriginal form and leaves the dynamically created on open. If I place a call to form2.close() in the yes handler sub I get an error that it is not declared. How can i close this second form?
View 4 RepliesIn my program it detects if there is more than one monitor connected. It then creates a form on each monitor screen and you just click on the screen that you want the program to run on.
Here's where I'm having a problem. Everything works great, but when I load my MAIN form how would I call those programmatically created forms? I can't just do frmYou.close.
Here's the code I use to create the forms.
Public myScreen As New Point
Public ScreenReady As Boolean = False
Public sX As Integer'holds screen x width

I'm going through All-In-One Code Framework Coding Standards document and one of the recommendations is to add a file header comment at the start of every human-created code file. This is the first time I've seen such a recommendation and to me it's just an unnecessary and ugly clutter but I'm wondering if someone could explain why M$ recommends this?

I have a dbf file. I saved it as a csv file and can open it in excel.
But i cannot open it in VB.net using programming and OLEDB connection.
If i copy all these content, paste it in a new excel sheet and then save it as csv file. My VB.net program reads it absolutely fine.
Any idea what might be wrong in saving the file directly from dbf to csv using excel?

I am trying to add text to an already created file on vb.net. When I run the program there are no errors and it writes everything to my liking, but currently when it goes to save, it makes me create an entirely new text file with any name I choose to give it. What I need to do is for it to automatically get added onto the end of an already created text file without deleting any other part of the file, which we will call "data.txt." Here is the code I already have
Imports System.IO
Public Class Frmadd
Const FILE_NAME As String = "data.txt"

I have an aspx page in VB that fills a pdf with data from a web form.I'm using iTextSharp for this and I have no problem with this.This is the second time I've created anything for pdf's and I'm using the code from the first script.The first script wrote the filled in pdf to a directory on the server where one person could access those via another aspx page. I wrote that code probably a year ago.Now, instead of having the filled in pdf sit on the sever, I have to email it, which I was successful at doing.The only issue left is to delete the filled in pdf from the directory.I tried to use file.delete(), but I got an error stating the the file was being used by another process.how to stop the process in order to be able to delete the file.[code]

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")

I have written VB.Net code that will read a users outlook inbox and searches for messages that contain a particular string in the subject line and then move those emails to another folder in outlook.Recently I have had to create a small app that does the same thing except it saves the emails in the .MSG format and places them on the network drive.What I can't figure out is how do I get the outlook object to see the network drive after the fact.
After the emails are saved in the MSG format on the network, I have to create another application that will reside on users computers that will use their outlook to read these files again.I can easily attach to an existing outlook folder and read what is in it but the network drive path is not an outlook folder and never will be.
Edit: I figured out how to save as new, now all I need to do is save an already created text file.
