I'm writing a program for my job in which we are keeping track of employees usage of food at work. The form in question interacts with an access database to a binded control with labels and textboxes. This form I'm working on is the user view which doesn't allow them to input their username, I have the user name saved to a variable but it will not display when I the add a new record. I tried many things but I'm just getting frustrated.
Is there away to add data to a row that is not displayed on the screen in a textbox for the user to see? There are 3 different "cells" (textboxes) I want to be filled in by other code without the users knowledge.
I'm currently using MSAccess 2010 and Visual Studio.net 2010
I want to see if anyone has used one table that has a primary key (not displayed) in the DataGridView. Then use a text box on the same form to call and group what if viewed in the DataGridView table. I want to group the displayed data of the DataGridView by the primary key of both tables.
I have a datagridview with 3 displayed columns and 10 columns overall. If I run the program the gridview start with the first column visible and displayed. Now i want to scroll with the vertical scroll bar.
If i click on the "right" button of the scroll bar my DataGridView1.Scroll - event says: DataGridView1.Columns(0).Displayed=True DataGridView1.FirstDisplayedScrollingColumnIndex = 1
So this means "yes, the first Column is displayed but the first displayed Column is the second one!"
This doesn't make sense to me. Is there another opionion to this Problem, or is this just a small bug?
I use Visual Studio 2008 Pro (Visual Basic) with .NET Framework 3.5.
I am workinng on an aopplication using the DataGridView.My intent is that the DataGridView is displayed with four columns, the user clicks on a row in any column and the complete record for the selected item is displayed and the DataGridViewis no longer in view.
The code to do this is in the event "dgvCollections_CellContentClick" and the function works exactly as I want it to.The problem is that when I want to sort by a specific column I click on the column header and not only does it sort , it calls the 'CellContentClick' event and the details form is displayed, which I do not want to happen.Is there a way around this problem other then using the "dgvCollections_CellContentDoubleClick" event to select the detail? This was what I did as I sterted this project and I found that the double click was very sensitive and often did not work. The single click is much better for the eventual user.

I am using a DateTimePicker to allow the user to select dates between which, info from a database is selected and displayed in a DataGridView.This works fine exept that the dates selected by the DateTimePicker seem to bring back results in US date format!
If I do a debug.print (DateTime1.text), the date is in UK format i.e 11/05/2009 but when these variables are used in a Select statement, the dates returned seem to be in US format e.g. selecting dates between 01/04/2009 and 7/05/2009 selects dates between 04/01/2009 and 05/07/2009 when the results are displayed in the DataGridView!

When a user clicks the + button on the binding navigator, I want to set the displayed item of acombobox to the value displayed in a label. The combobox is bound to a field in the table.

This is are the parts of my system where my problem occurs: - Search Button - List Box1 - TotalTextbox - Button - SQL Database with a Column named "Amount" and it only contains numbers Datatype is System.String
So, basically a user clicks the Search button and searches for a data in the SQL Database, and the result of the search displays in different Listboxes including the "Amount" Column from the database, which has it's own Listbox named "Listbox1". the Listbox is now filled with numbers.
Goal: The goal is to get the Sum of all the "Numbers" Displayed in the Listbox1, and the Total is then Displayed into a Textbox via using Click event or automatically.
The Code:
Dim sum As Double For x As Integer = 0 To ListBox1.Items.Count - 1 sum += CDbl(ListBox1.Items(x)) Next TotalTextBox.Text = sum.ToString
And i got this Error: Conversion from type 'DataRowView' to type 'Double' is not valid.
I ended up with this..
Dim sum As Double For x As Integer = 0 To ListBox1.Items.Count - 1 sum += Val(ListBox1.Items.Item(x).ToString) Next TotalTextBox.Text = sum.ToString
But the values are not adding up, the total is always at 0. i've been searching for hours now from the net to a better way of doing this.
Here's a quick Flow on what im trying to accomplish here. Record from Database -----Displays on---> Listbox1 -----User Clicks--> Button1 ----Displays Total sum on----> Textbox1

I have a question about binding the datasource (MS Access database) to a listbox in a VB form. I have created a listbox and in the datasources explorer I have my datasource say SampleDS. I have several columns inside my datasource, say name, age, address in it. If I select name and drag to the listobx in the form, only the entries in the name column will be displayed in the listbox.
I want to know how to filter the name based on criteria. For example, how do I display names whose age >25?
