I am trying to open an excel file and write to it as data becomes availableI can create an instance of excel and write to the selected worksheet once. But, I can't seem to write back to the existing file. I keep on getting a null reference error when I try to send new data to the file.The function I am using will run once, but when it returns to the main form, I lose the values of xlApp and xlWorksheet. It appears that going in to the function makes the original values null.

If you copy the data file to your project, it will be copied to the project's output directory each time you run the application" and the options are (yes , No , Help)
If I choose Yes I will not be able to make the application 'device independent ' since it will not be copied under the bin , and if I choose No , changes won't be applied to the DB

How would you add data source to your combobox from a combobox that is connected to the access atabase?they are both ın the same form of course and the software language ıs Visual Basic. I ve got two comboboxes that I need to connect with eachother combobox1 is showing the "itemsonsell" from the "table_items" table from my access database, the second one should show the "prices" value from "table_items" depending on which "itemsonsell" item is chosen on combobox1,I ve done the solution below,but it didnt seem to be working,it is showing all the "prices" that are under the "table_items" table's "prices" class.

I can't seem to figure this out. I basically am trying to write a class, not a usercontrol, that can show up in the ToolBox. I want it to act similar to how a ContextMenuStrip or BindingSource does, in that there is no UI when you throw in on the Form, it goes down to that bottom part (name?).
1) What do you call those types of components?
2) Why won't this test class that I wrote do the same thing?
vb.net Imports System.Windows.Forms
Imports System.Runtime.InteropServices
<ClassInterfaceAttribute(ClassInterfaceType.AutoDispatch), ComVisibleAttribute(True), _
System.ComponentModel.ToolboxItemAttribute(True), System.ComponentModel.DesignTimeVisible(True)> _
Public Class FilterMenuStrip

If I try to add it to the ToolBox, I get a "There are no components in '<The DLL>' that can be placed on the toolbox."
Could anyone point me the way on how would I be able to add my custom Form template to VS.Net?

I have an application that i have developed which requires me to run a method in one of the classes on a timely basis. Basically, calling the method at an interval.I can do this if there's only a single object, but the number of objects that i have to create depends on the number of entries in a table. I was wondering if it's possible to add timer control dynamically and make the tick even call objects' methods at an interval.

I have a datagridview on form1 but I don't want users adding data using datagridview, instead, I wanna use details view. So I created a form2, dragged and dropped details view on form2. I changed the Addnew on BindingNavigator to None and added a code to the Addnew click event handler to call the form2 out so that I could add data from there. But, when form2 loaded. the textboxes pulled out all the information from datagridview. I did not want that, I wanted all the textboxes to appear empty when it was loaded. so I deleted all the textboxes and added my own textboxes so that they appeared empty when form2 was loaded.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Me.VendorTableAdapter.Insert(TextBox1.Text, TextBox2.Text, TextBox3.Text, TextBox4.Text)
Me.VendorTableAdapter.Fill(Me.VendorDataSet.vendor)
End Sub
I added the above code to allow users to add data into datagridview using data details view.
I'm displaying data from a database in a datagridview, but the player also needs to be able to add new rows, which isn't allowed because the datagridview is data-bound. What is the simplest workaround to this problem?

UPDATE: OK, something's really screwed up. When I inspect the Me object above, it isn't even putting out the kind of object I expect. I think I may need to piece together the solution again.
As a preface, I am brand new to using SQL Server 2005; I know how to use the SELECT, UPDATE, DELETE, and INSERT commands and that's about it. I am also using Express Edition on my local PC (E8400 processor, 8GB of DDR2-800, 2 x 640GB SATA-II HDD in RAID 1)
I have a table that I set up with 8 columns, all are NVARCHAR(Max) and I allow Null. I know in concept what a primary key is, but I don't have one (nor do I know how to set one up).
My VB.NET program that I'm working on is downloading a historical stock price chart from Yahoo, for every single ticker symbol in existence. The first 50,000 rows or so I added was super fast. Then I went to bed, and when I woke up it was still running - but the rate of row additions has slowed waaaaaay down; I noticed this around row 300,000. I always expected the rate of row addition to be constant over time, but obviously this is not so!
From browsing other Stack Overflow questions, I suspect my slow down is related to my piss-poor table setup. If this is the case, where should I begin first to fix this, and are there any good resources I could read up on to get started? I'm hoping this is something simple I can fix [code]....
