Dim newRow As DataRow = Dataset.Tables("TableName").NewRow newRow("COLUMN_NAME") = Binded Control Value DataSet.Tables("TableName").Rows.Add(newRow)

I am creating an Excel add-in written in VB.NET. I would like to bind KeyDown and KeyUp events to the spreadsheet to record when the user presses and releases the arrow keys while navigating the spreadsheetIdeally, these events would be built into Excel alongside the native SheetActivate and SheetSelectionChange events, for example. Alas, they are not.

Visual Basic Project - Student Check In Form using an Access database backend This form needs to draw information from an Access database containg tables for STUDENT, INSTRUCTOR, and SECTION. These all need to have primary keys and ids. When (the user) clicks on the drop down box that displays all the sections:
{Table Tennis 1, Table Tennis 2, Table Tennis 3, Billiards 1, Billiards 2, Billiards 3}This should populate the listbox or datagrid from the STUDENT table with the Students that have the same SECTIONID as the SECTION selected in the drop down menu above.
After the Student list has been populated (the user) clicks on a student name in the listbox/datagrid and this inserts that student into the CHECKEDIN table that has a datagrid/listbox associated with it.
This is a great project to practice connecting a database to Visual Studio 2008 .net and playing with the data that has been pulled in. You could use SQL instead of Access.
I thought i am doing fine with my project..The access level is fine.. when i login as "ADMIN". I can change the password.. But for other users, if i click save nothing happens but if i click it again it will save(In my savebutton event the txtbox is cleared if saved)
Here is the code for my login(this is the access level part)
If reader.Read Then
Dim access As String = reader.Item("Position").ToString
Select Case access
Case "ADMINISTRATOR"
Me.Hide()
[CODE]...
AND THIS THE change PASSWORD PART
Private Sub UserPasswordUpdate()
Try
Using _connce = New SqlCeConnection("Data Source=" & _dbAlumniTracking)
_connce.Open()

In c# you can auto property a value with different level of access for the get and set . . . e.g.
public String myString
{
get;

I have a login page, which a user will have to enter username, password and accesslevel. Accesslevel is either 1 or 2. 1 for admin and 2 for users who are restricted from using certain functions. I have this module set up so that I can make use of the accesslevel throughout the forms that I have.

So I have this program which I can use to drag files in it and do something with it, and when I run it as administrator, it doesn't let me drag the files in at all, but when I run it normally it does. Is there a reason behind this? And how would I go about fixing it?

I have created a simple program which uses a two tier structure of SQL Tables.At the top level, one record holds the date of the activities and linked to it using its primary key as a foreign key, three subordinate tables hold time stamped records.The issue I have been unable to solve is that before adding any of the lower level records for a given date, a newly added top level record must be saved to the database.Doing this manually is simple - but can I rely on my users to remember to do this before they start plugging in the lower level data?I thought not, so I am looking to save the top level automatically.I've failed miserably but I refuse to believe that it's not possible.
View 14 RepliesI'm using VS 2010, and I did a project using VB and a database in Access. The problem is that when I try to put that "application" on other computers, sometimes, is not working. I thought it can be because on these computers they don't have access, but on one computer, is running another app which is using Access and there is no Access installed. How can I check if my application requires Access to be installed or not?
Here is a example of how I did the connection:
Public AccessOLEDBConnString= "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" & myfullpath & ";Jet OLEDB:Database Password=password"

View 1 RepliesI have a form with a button that brings up a different form. In some versions of this program (don't ask), the second form is shown non-modally, but in my version it is shown modally. The point of that last statement is that the second form can be either modal or non-modal, so an answer needs to handle either one, but the modal option is more valuable.If form 2 throws an exception that is not handled, the exception is caught somewhere on Form1, though the exact place that it is caught is largely dependent on where the exception was thrown from. The question is this: I need a means to trap all exceptions raised on Form2 or anything called from Form2 such that no exception EVER propagates out of Form2 to be caught in Form1. The reason for this is that Form2 HAS to perform some cleanup for reasons that I have zero control over. That cleanup doesn not absolutely require user input, but it would be good to have some.Is there any event that is fired if a form is exited due to a call stack unwinding as an unhandled exception propagates up the stack?
