I have a database along with a dataset. Everything is displayed as a gridview.When I run my program and save my entries, everything works fine. I go through other forms and items are still saved but as soon as I close Visual Studio and restarts the program, the items previously saved are no longer available and nowhere to be found

I have a program where you have three entries, CD name, artist, price and it goes into a listbox and .txt file when closing. I have to have a message box if you enter the same CD name. I have a code to open the .txt file and compare strings but I need to change it to compare only the CD name and not all three entries. Is there a way to do my string compare against my listbox without opening the .txt file?? The program loads the listbox from the .txt file when opening. Private Sub btnAdd_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnAdd.Click' adds CD information to the list box
' declare variables
Dim strName As String
Dim strArtist As String
Dim strPrice As String

I want to set a certain column to true or false automatically based on what value another column has entered. I managed to get this working by myself using the 'SQL Pane' in VB and testing it by using execute sql but I don't know what to do now. I assumed that I could just save it and it would work from there but that's not the case, it dissapears from the SQL Pane if I close the project (even though it worked fine when I ran the project the first time), so where do I put it/what do I do with it in order to get this to work?

View 5 Replieswhat I am trying to do is get a program to load data from a text file with multiple lines in the form "Name, Type, Stocklvl, Price, Location, Reorderlvl" then display it all in a data grid. From where it can be viewed and edited as well as saved back into the original file stock.txt as well as generating a separate file reorder.txt which includes data on what needs to be reordered and the date which updates on program exit. I have chosen to use datagridview something I'm unfamiliar with as I figure It'd probably be the most functional to meet my needs of displaying a lot of data clearly as much as 200 items.
View 22 RepliesFirst time user on here, basically have been teaching myself VB and I enjoy it quite a bit! Basically I have a program now that has the File Drop-Down Menu with Open and Save options. I want to open and save in a .txt format. The open command will need to place the text in TextBox1 ; and the Save command will need to take the text from TextBox2 and save it as a .txt. I have gotten to the point where it will save it to a specified .txt file, but I would like the user to be able to "browse" the computer for where to open from and save files to.

I created a form with 4 textboxes, one date picker, time and combobox. Now the problem I have is that I want to save all the values in these boxes in a folder which depends on what is selected in the combobox.
Source:
vb.net
Private Sub ListBox1_SelectedIndexChanged_1(ByVal sender As System.Object, ByVal e As System.EventArgs)

The idea is that if I select 3 in the combobox, the files has to be saved in the folder 3. This folder is located on a server located in the LAN.

I am working on saving excel objects to a directory of my choosing. I am able to use a folder browser dialog to select the save location and the saveas method within the excel interop and i am able to create a file in the folder i select with the name i choose.

I'm stuck with this problem: How to save what a user does to the program. For instance, in my program, the user can change the text of the button to whatever he/she wants. However, when she/he reopens the program, the button text she/he made doesn't stay there; they have to rename it. I just wanted to know what the code was to save the user's achievements.
