View 1 RepliesI'm creating an open-source web browser in VB.NET Express 2008 and I've created a User Setting named History to save a collection of strings for the browsing history. However, when I try to load the history form at runtime, only the first item (of the three I added) shows up in the listbox. Below are both examples of code I have tried to use to accomplish this task.
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
ListBox1.DataSource = My.Settings.History

how can i save load a listbox? [code]
View 2 RepliesI've got a problem, I'm making a program that gives you the choice to add items to a listbox, these items are text. When the form loads, i need it to load text from a file into a listbox. For every line I need it to add that text to the listbox. My problem is when it loads, there's an extra line, but that's only after I close the form and open it again. The reason it happens when the form unloads is because the listbox items are saved on form unload. Now, I believe the problem is my code to save the items:
Dim Env As String = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments)
For Each item In Form1.TP1.Items
Dim Save As New SaveFileDialog()

Where, ";" is the Delimiter and data is just one line only. "A" has to load in TextBox and "Cat,.....,Bird" has to load in ListBox, one line per animal.I've already read the text file and load "A" into text box. But couldn't figure out how to load rest of the data into list box.

How do I save the Dictionary and other variables in one single file, which can only be read by my program itself?
I have a set of labels that contain number values that need to be saved into a txt file and recalled from a text file by a button click event.
Ive been searching these fourms for days trying to find the answer to the save / load data problem. From what I understand, XML should be used to do this. But no matter how much I read I cant make sense out of how to solve this issue. I just need a simple and quick fix that dosen't have to use XML[code]...
I have created a program in Visual basic 2010, the program contains many different objects e.g. datagridview, textbox, buttons, graphs etc, which can all be modified by the user. The user can also select a file using 'SaveFileDialog'.
Is there a way to save all the properties associated with each object to this file and later load the program back to exactly the same state it was saved in, after the user has selected saved file using 'LoadFileDialog'? Preferably in binary.
I can do this the hard way in ASC11 format by interrogating objects user editable properties and saving them. I would rather not use this method as it will require a lot of code and any future program changes will require a lot of extra work.

View 14 RepliesI have a tool connected to access database. It retrieves the database based on certain input conditions from 4 textboxes, 1 list box. The data from database comes to a datagridview. I have to enter certain values in a particular column in datagridview and continue with my calculations.At this stage I wan to save my file with the data I have entered so far. Is there a way i can save this data into another file (for example say " SAMPLE"), so that when I open the SAMPLE file from my tool it should display all the values I have saved in the respective controls.

View 7 RepliesI have a form with a listbox that when the form is opened I need it to display info from a file. I don't know what would be easier to work with Excel or a txt file, but it is in this format:

999-555-8618[code].......
I would like it to populate the list box when the form is loaded, but if I have to use a button to tell it to load that is fine also.On the same form I have 4 textboxes that ask for each of the above items (name, DOB, Level, PH#) and a button that when pushed I want it to save it to the same file where the above info was pulled from in the same format.The Show Contacts button doesn't have to be used if it is not needed.
This problem seams to be in other forms without any concrete solutions. I figured id post it here since i am running into the same problem and i am sure you have at well at some point (if not then you will soon...lol). The problem is this error is appearing when i open a form in designer mode.
