I have a listbox that loads all text files in a set folder on form load. From those files in the list box, I want to permanently delete a file from my pc, thru a button that I'll eventually add a yes/no msgbox before deletion. Just to click on a file in the listbox, then the delete button and delete the file.

View 6 RepliesI'm currently trying to delete data from a dataset/datasource/database using visual basic. So here is the run down: I've built a program that can add, delete, and modify customer information from an Access database and I just got the add function working. Meaning, I can now add customers to the database and it is sticking to the database. I re-ran the program and even restarted the computer the computer and the data is in the database. This works fine. However, now I want to get the delete button working but I'm not sure why it isn't deleting some of the fake entries I made just to test out the add feature.Here is the code I am using:
Dim delCompany As UMD3.CompaniesRow
delCompany = UMD3.Companies.FindByCompany (NOT SURE WHAT GOES HERE)
delCompany.Delete ()

[VB 2008 express edition] i am doing a application data grid view bound data from MS access (.mdb) as my dataset. the dataset have 5 tables, each table consist of ID, Items, Rates, And Amount, i face some problem here:
a) cannot delete row from the table, (using binding navigator but error)
b) how can make a opendialog to load the .mdb file dataset table in to the datagridview?
c) how do i save table in the datagridview into the MS Access file ?
This is the strangest thing, I can not figure out why this is happening. When I delete a radio button from my form which is used to filter data in a database Form_Load stops working.My project consists of a database and a web browser. The database has a search filter options.[code]For some reason it didnt load my settings on start up. I made a button which displayed True/False in a text box to check if it was saved in my settings, it was, it just didnt want to load. So I deleted it and everything broke! Nothing in the code is referenced to the RadioButton or its code.
Have I done something wrong or is VB just messing with me? There is obviously a bunch of more code, I just posted what I think is relevant to the issue. If you feel something is missing, tell me and Ill post it. ied to change the RadioButton with a CheckBox, and I changed the code from "Me.ExampleTableAdapter.FilterHide..." to "Me.Example TableAdapter. Fill...", which is the same as in Form_Load. It works if it starts checked. If I remove this code or delete the CheckBox nothing works even though the same code is in Form_Load. If I start off with the CheckBox in an Unchecked state nothing loads, if I check it everything except the Browser works for some reason.
1.) I dragged my detail view over to the form window to create a bindingnavigator, fields, etc.When I press save on the form, the database is temporairly saved.However, if I save my visual basic project, I lose all the changes I have made to my database.Is there a specific save command that updates the access file permanently?The default command added by dragging over the dataset does not work.
2. My database is accessed with the following string:[code]However, doesn't this mean that the database MUST be placed in that specific folder on any PC? Is there a way to simply build the database into the compile so the program automatically generates the database when installed on anyones computer?
3.) This might be fixed by fixing the previous two issues, but if I compile my program and try to install it, I get an error message "Could not download the application.The application is missing required files."

The insertion part of the form works great. But my problem is in the form load part......If i leave a field blank(Null),then perform Save operation,close the form after successful insertion and then reopen the form,then it retains the previous values during the form load......This is only in case where i leave a field blank in the previous data entry in the database.......But if i enter values in all fields then form load is working great.
