I have a problem. I'm working on this advanced web browser with my friend, and we made a favorites feature. So, it works and all that, but, after I close the executable file, it doesn't save anything!
Ex:Starting Up, adding Google as new favorites, then closing the browser. Starting up again, 1 hour later, but there's no Google Here's what I put for saving the favorites (please do not steal the code Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click

Option Strict On
''' <summary>
''' The TreeViewDataAccess class allows the nodes within a TreeView to be

I have managed to create a connection to the database and am able to save information to it from my form, the form contains 22 textboxes, a save and another exit button. I have set the form to retrieve data in the form_load. I have used the "UPDATE" SQL command on the save button and it does save the data on all 22 textboxes (all textboxes are linked to their separate columns). But only one record will be needed that is why I did not use the "INSERT" command.
The problem arises when I click the save button, all (19) textboxes are saved but when I retrieve the text (by reloading the form), each of the 20, 21, 22 textboxes (only) the text of the 20th textbox keeps on moving tho the next textbox e.g. 20>21>22>20>21>22 is interchanged amongst themselves.

I have a datagridview which has columns which are bounded and unbounded. My problem is when the user enters several rows in the dgv, only the data found in last row is saved in the access table. For example, if the user enters 2 rows of data, when he clicks the save button, there are 2 rows saved in the access table but both rows contain the data of the last row in the dgv. Below is the code of the save button.
Private Sub btn_Save_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btn_Save.Click
For Each dr As DataGridViewRow In dgv_RMS.Rows

I am trying to use the Tag property of a control to save it's value so I can reuse the new value when the program runs again.[code]I am trying to use this like the projects settings property where you can save your settings and they will come back when the program runs again. (my.settings.save) Perhaps the Tag property won't work like this. Maybe I just don't understand it.

I want to make a button that opens a program. Just for the sake of this post, we'll call the program Notepad.I want the users of my program to open Notepad, but not everyone saves Notepad in the same location. Is it possible to save a value (and the text in the TextBox) so the user doesn't have to retype it every time the program loads?

I want to save my preferences for a program. I just want to know how to do it, since I cant get how to save this file at my documents, because every computer has a different name and username, but using the My.User.Name returns 'USERNAME-PC-USERNAME' which doesn't work. For example, I want the program to create this text file 'CPreferences' at 'C:Users'username'Documents'. And then when the program is re-opened it will automatically load this file into itself, the file will basically contain 2 lines:

I need an advice in resolving a little problem. I need to save 3 queries at the same time in my code.[code...]
This works fine but, my problem is I need to be able to stop any of the three procedures from executing if there is a problem with any one of them. Please note that these are three different stored procedures saving to different tables.
At the minute, if there is a problem, the procedure with the problem will fail to execute while the others will. I need to stop all of them from executing.

I have written all that is required at this point and have published the program. I thought that global variables were saved when the program terminated but, as I found out, they aren't. If anyone has any way of making the variables keep their values between uses of the program I would be very grateful as if the program is being run for the first time some global variables need to be set straight away (I have done this code). The variable types are: one boolean and a few strings.
