VS 2008 Populate Object With List Of Windows Users Without Changing Datatypes?
Jul 25, 2011PROJECT TYPE: Windows Forms Application
LANGUAGE: Visual Basic
.NET VERSION: 3.5
IDE: Visual Studio 2008
OPTION STRICT: on
OPTION EXPLICIT: ON
I need to populated a ComboBox and a CheckedListBox with a list of the Windows Accounts on the host computer. I also need to the user to be able to apply settings to the users individually. Thirdly, I need to find a way to add a startup registry key in the CURRENT_USER for a different user than the "Current User" (For example: User1 is an Administrator. User2 is a Limited Account [can't modify registry]. User1 needs to add Registry key to User2's "CURRENT_USER". This is a parental control application so the Admin accounts need to be able to access the registry from all users without affecting all users at once. I do not have any code to paste because I still have not the foggiest idea of where to start. I think it probably has something to do with an array (I have no experience with arrays whatsoever) but I am stumped from there. I'm a new, self-taught programmer so I speak idiot at times,
Summary of Questions
1) How do I retrieve a list of Windows Users?
2) How do I populate the objects above with such a list?
3) How do I interact with the items on that list (specific user accounts)?
4) How do I modify another user's CURRENT_USER Registry key?

View 4 RepliesFormat Date In Data Grid View Object Not Set To An Instance Of An Object?
Jan 29, 2012I'm trying to set the format of a column in a datagridview.When I put the format statement in the on load event for the form, it has no effect. When I put it in the cellformatting event I get the "Object reference not set to an instance of an object" error. I checked the column name. What I am doing wrong?
This is the code:Private Sub MeetingTblDataGridView_CellFormatting(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellFormattingEventArgs) Handles MeetingTblDataGridView.CellFormatting
Me.MeetingTblDataGridView.Columns("Starttime").DefaultCellStyle.Format = "HH:mm:ss"
End Sub What I'm trying to do is get rid of the date part of a Date/Time field (stored in an Access database) in a datagridview column.

View 6 RepliesPopulate PDF Document With Data From SQL?
Nov 3, 2009We have a lot of PDF documents and would like to save information filled in by the user in SQL database and then pre-populate the answers in multiple PDFs for printing. We'd also want user to digitally sign the pdf and store the signature in database. Ideally I'd like to create VB project with form that users would fill in and then information should "flow" into existing PDF. Then later I'd setup some reports based on user-filled information. We probably will purchase Adobe LifeCycle software to use with PDF.
View 13 RepliesSQL Data To Populate Graph?
Jun 15, 2009I have created a function to create a string to populate a y axis with data:
Function talktosql() As Double
Dim ConnString As String = "Data Source=MARK-WORKMSSMLBIZ;Initial Catalog=Yahoo_data;Integrated Security=True"
Dim SQLString As String = "SELECT [RDSA.L] FROM yahoo_data.dbo.XLON"
Dim SqlDataAdapter1 As New SqlDataAdapter(SQLString, ConnString)

so it should for example come out like this:
Dim yValues As Double() = {55.62, 45.54, 73.45, 9.73, 88.42, 45.9, 63.6, 85.1, 67.2, 23.6}
I cannot seem to get the data from the function into the right format to populate "yvalues".(the msgbox that I put in at the end in the first code renders the result "0")

Populate An Ado.net Dataset With Only Changes From The Data Source?
Dec 14, 2011I have a simple access database that a log record gets written to a few times an hour.
I'm trying to make a DataGridView that shows that data as it arrives.
My "Solution" is simple;
when a user clicks the view -> read from the database (fill the datatable) -> update the view.
Not what I dreamed of, but functional, if totally sub-optimal.
However, my "solution" is a dud, using fill draws every single record from the database, even if there are already 599 on screen.
Really, I just want fill the datatable once, and add new records as they arrive (or on click if needs be).
Bonus point if you can also explain another way (that isn't called so often) to hide the ID column, and change the header of column 1 (named DateTimeStamp) to TimeStamp.
