ListView Data Save Into Text File
Jun 9, 2011
I have a question because in my I.O.File. I use this to save the data in the listview in a c: est.txt but the problem is that it only save one data and every time I click the save the previous data that I save is deleted and it change the new one that I save. And also when I click the remove in the listview it will also delete the data that save in the c: est.txt and the format should like this
First name | lastname | address |
rae alanah new york
john smith los angeles
Here the code that I did...
Dim myFile As String = "C: est.txt" '//file location
System.IO.File.WriteAllText(myFile, TextBox1.Text & " " & ComboBox1.Text & " " & TextBox4.Text & " " & ComboBox2.Text & " " & TextBox3.Text & " " & TextBox2.Text & " " & TextBox5.Text)
Or you can also create new code base on ur understanding. This is the first time I use the I.O file or file stream in vb.net because my crystal report does not detect my database that's why I need to do this.

I save data from datagridview to text file. I also load the same data from text file into datagridview for edit and update the same thing to text file. Let say this text file i called as Drill.txt. I have another text file called header.txt which need to match its value with the value of Drill.txt file then overwrite value from Drill.txt to header.txt. Now i want to make my Drill.txt in encrypted format to prevent anyone to open that file and modify out of program. They only can modify it through the program

I'm using Visual Basic Express 2008 and I need to upload and sort two data text files (notepad) in a listview box. It doesn't have to be a listview box I chose that because it has nice options for columns. Anyway I've got the code set up to open the dialog box and allow the upload of multiple files. I've also got it set up to show separate columns, movie titles and box office amounts, titles in one file box office amount in the other. What I nee sorting the data once it's uploaded so the movie titles show in one column and the box office amounts show in another. Currently everything is showing in the left most column. I'd like to be able to represent the data seperately also so I can format the dollar amounts into currency. Here's what I've got so far:
Private Sub LoadButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles LoadButton.Click
Dim DialogBoxResults As System.Windows.Forms.OpenFileDialog
[code].....

I'd like to save data to a text file on a remote server I have. There are no security issues here, just the method.
Dim FILE_NAME As String = "123.456.789.012/variables.txt"
If System.IO.File.Exists(FILE_NAME) = True Then
Dim objWriter As New System.IO.StreamWriter(FILE_NAME)
[Code].....
I know it's not the most secure way of doing things, but the end data has to be in the txt format, otherwise I'd have used MySQL.

I have a standard form that you can enter data into.I want to take that data that is entered, and save it to a text file once I click the submit button at the bottom of the form. The form could have up to 500 entries into the form.

i am currently working on an Application Manager that basically will free up my desktop of all my shortcuts by adding them to a program, or in my case, the listview object. Basically, so far i have set up a toolbar on top with a few options that will add listview objects, listview groups, remove those, and some other help and support things.
What i want to do is allow the user to add a listview object, which will be an application shortcut- they can choose the name, the icon, descriptions, whatever. (In essence, i am basically moving the desktop style of shortcuts into an application, where you can categorize and organize these shortcuts).
The questions i have are: 1. Is the listview object a good option for what i am trying to accomplish? 2. I saw that you can import imagelists, but how can i incorporate that to include icon pictures selected when a user adds an application? 3. How do you save listview data? 4. Anyone have a good strategy on how to approach this project? 5. Do i/Should i make an 'application' class that handles all the application information rather than using direct listview methods?
