I created a custom control and add it to a form programatically.
The user can add and move them all over the form.
The problem is when I want to clear the form of my user control I don't know how.
I created an array of my control called ctlCorkNotes
Say I create ctlCorkNotes(1) and now I want to delete it.
How do I do this so it is gone and would have to recreate it to show up again?

I have a DataGridView and i binded its datasource to the datatable.Now i want to edit and delete the data from the datagridview in this way:I did this in asp.net and now i want to do the same in the vb.net.What i want to do is that each dataGridView row will contain two link button called edit and delete(in the above figure they are the imagebuttons of asp.net),when i will click the edit link button then it will change to update and cancel link buttons and the contents of that particular row will be shown in textboxes so that the row can be edited by the user.

I found out there are ways to Select, Insert, and Update Excel file by using OLEDB. But the limitation is that we can not delete a record.My idea is to delete row (instead of record). The question is how to programmatically delete row in excel, by id selected?I want to delete the row where id = 3. I can grab the id, but have no idea how to delete the row which contains the id 3.

I am having some issues with an application written in VB.net.
As part of a routine, an sqlce database gets backed up before the routine then if an error occurred gets restored. I am using system.io methods copy and delete.
I have released all the objects (connections, commands, datareaders) asscociated with the sqlce database by disposing them if they are not nothing. I also do a GC.COLLECT however when my delete command runs, an error message says it is open by another process. The PROCEXP.exe process explorer tool says it is attached to 4 undefined processes. After a while in debug mode, these clear and I am able to delete the file. However this is not acceptable as my program cannot "wait around" until they are released! I was under the impression that object.dispose forced an immediate disposal rather than waiting for the garbage collector to clean up (if you were just to use object=nothing), but still there appears to be a finite time before these objects are released.
My question is, is there an alternative way of checking (programatically in vb) for what is holding open an sqlce database (or in fact any other file for that matter) then killing these processes?

I have a DataGridView that I'm trying to populate using a For loop:
Dim serverName As String = SQLServerName + "" + Instance
Dim server As Server = New Server(serverName)
Dim Datatable1 As New DataTable
For Each database As Database In server.Databases
Dim row As DataRow = Datatable1.NewRow
[Code]...
The DGV has been designed with the designer (columns, layout etc). Using the above the DGV does not populate. I was using a ListView for this but I need images in a subitem so have switched to using a DGV.

For my application i'm trying to generate a datagridview with a comboboxcolumn in it. This combobox I wanna fill with some data from a table in my database.I've figured out how to add items to the combobox but I can't assign a value to it. The combobox is suposed to fill with product name items, and the value should be the weight of the product, so later on i can calculate the total weight.But now it's just displaying the product name, and the value is also the product name.

I am using Visual Basic 10/I have 2 datagridview tables. The main datagridview can be edited by the user; adding/removing rows, changing data in text/combo columns, sort, etc. 2 columns from the second datagridview are a carbon copy of 2 columns from the main datagridview. I have achieved this by binding both datagridviews to a dataset. So that when I edit the main datagridview the effects are automatically replicated in the second datagridview.
Before I bound the datagridviews to the dataset I had a fully functional system to save the content of the datagridview to a text file and read it back in. This has now stopped working with the error message 'Can't edit a bound datagridview programmatically'.

I have a unbound datagridview for which i want to add a new row at the bottom when a user selects a value in the 2nd column of a 9 column DGV. The issue is that i have a default value (0.00) programmically entered into the last row once this 2nd column value is entered. When i call DGV.rows.add() it places the new row at teh top, but when the user enters or changes the last coulmn value then a new row is added at the bottom. I want my programmically added row to be at the bottom and have not found a way of doing this.
PS. What is the logic behind this different behavior on adding rows?

If have a textbox that is used to search a datagrid when a user types into it. This seems to be working properly, as the correct row is highlighted when text is entered. However, something isn't quite triggering properly because if I try to get the selected row, using dgSchedule.CurrentCell.RowIndex, it always comes up with whatever the last row that was physically clicked on, rather than the row that is actually highlighted.[code]...

how to connect a SQL Table to a DataGridView that was previously created programmatically. Basically, at run-time the user names and creates several empty SQL Tables and DataGridViews. After that the user selects from a combobox the name of the SQL Table and DataGridView that they want to import data into, then clicks a button named "Import"...after clicking "Import" the user navigates to an Excel file, chooses a worksheet, clicks a "Continue" button and then the code successfully connects to the Excel import file and SQLBulkCopies the data to the SQL Table...next I need the imported data in the SQL Table update to the DataGridView...this is the part I can't figure out.
The challenge is the datagridview isn't hard coded it was created and named programmatically at runtime. So now the user selects the name of the SQL Table the data resides in and the name of the DataGridView from the combobox "moduletableCB" and I need the code to update the datagridview.

How do you change the column type in a datagridview programmatically? I have several tables that I want to allow the user to update using the same form. Depending on the table, I need to change the column type to a checkbox instead of text. Following is the code that I run (just exchanging the table name and column #). Everything works well as long as I don't try to change the column type.

Here's what I have so far
Code:
If item.IsSetLargeImage() Then
Dim largeImage As Image = item.LargeImage
If largeImage.IsSetURL() Then
