File I/O And Registry :: Save Data Of Objects To File?
Oct 4, 2008I have about 4000 objects of a class, each object with 20 members/variables, integers and strings, total about 80000.
I would like to save these to a file, and read them back into objects when the program starts up.
How would I do this in order to keep track of each variable? I was planning to have each line in the file representing the variables of 1 object. Hence 4000 lines. But basically I'm just looking for the easiest way to save and retrieve this data. Should I first convert the objects to an array of strings?
Save Multiple Objects To Single File
May 13, 2012I am trying to save multiple type of objects to a single file, objects are a custom class that I am able to serializable and another object is a word document that is not being able to serialize via binary. Is there a way to save multiple objects to one file using vb, also would it be possible to save files like how a docx is saved, that is a .zip renamed as docx but get access to inner objects.

Mar 17, 2010I'm using the SaveFileDialog to save listbox info into a text file. The files save fine, but when you go to save the file, if you hit the cancel button, it will overwrite the previous file you saved, because it's name was the same and it seems to save the previous file as the new name for your next file. Is there any way to catch if the user clicks cancel, and then exiting the sub if they did?

View 3 RepliesSave ListBox Lines Into A .txt File?
Jul 17, 2011What im try'ing to do is when a ListBox item is selected and the value has been given with a NumericUpDown box and the ''Add to orderlist'' button is clicked that it saved it to a file called "orders.txt", not at startup but when the first order is made.
Some requirements:
U can't order the same thing twice ( only edit it within the editor ).
The "orders.txt" has to open on a TextBox1 at Form2 ( the text editor ).
And the user can only change the order amount in the edit program.
Example:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
ListBox1.Items.Add("7226218; Hemlock; 22.55; 0")

Save Items In A Listbox To A Text File?
May 27, 2009I've been trying to figure out how to do this correctly for some time now, and I have seen no insight. I'm trying to successfully save all of the items in a listbox without saving items that are not there. What I mean by saving items that are not there is when it saves, it seems that blanks magically appear in the text file.Here is a sample of my current code to save.
[Code]...
I'm not completely sure if it's the loading or the saving that's causing problems, but what would happen is it would add a blank item to the listbox that I do not want.Here's a picture before the listbox is saved, look to the bottom left.Now here is what it looks like after: (notice the red oval)Does any one have any idea what could be wrong?If you want me to attach the text file, just ask.

Listbox, Objects, Inheritance And Polymorphism
Jan 31, 2012I wasn't quite sure how to label this but that should cover it all. I am using Linq to Sql classes to query a SQL Server table. That part is working fine. I'd like to add the records to a listbox and not just text. I can do this and it works. To get it to display something meaningful in the listbox, I have to override the ToString() function.
So, I've taken the base class tblVendor and created a new sub class tblVendorListObject that inherits tblVendor and overrides ToString to return Me.vendorName. I then use a foreach loop to iterate through the records returned by the query. Next, I create a new instance of tblVendorListObject and attempt to assign the current item in the foreach loop to it.
