I am an aid in a technology classroom at a middle school. They have 12 computers that must be logged into everyday. The teacher has given me the password to log in the computers for the students, because he doesn't want them to know it. The teacher's computer is linked to the other 12. I was wondering if it is possible to develop a program that has a list of the 12 computers with 2 fields, one for user name and password. These for each computer. You would enter the username and password and it would log in the computer. This would be done from the teacher's computer. It would make it a lot easier than having to go around and log in those computers. [URL]..

I have a VB.Net WinForm Program. I dynamically create panels with controls.Each panel has:
2 Labels
1 DataGridView
1 Button
Everything works fine the first time I create the panels.
Everything gets created, and everything is functional.
If I have to re-create the form, I get rid of the existing panels (and their controls) with this code:
[Code]...
When I re-create the panels, I get the panels and all of their controls except Buttons.When I step through the debugger, I see the buttons being removed, and I see them being created, but they don't appear in the panel

I am writing an application that requires button controls to be created at run time because the amoutn of controls created depends on data retrieved from a database.
I believe I am creating the control properly but I am not capturing the click event.
Code example:

myButton = New Button
myButton.id = "id"

I am looking at creating a Dynamic Menustrip.I have managed to write the code to add subItems to a Item. The root item is called item1 and when the form is run, item1 gets populated by items called subItem[0-5].I am wondering how do I assign an action to a subItem when click? At the moment I want a message box to popup with the subItem's name that has been clicked. I.E If subItem3 is clicked, I want a msgbox to pop up with "subItem3".
code
Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
For j As Integer = 0 To 4
Dim subItem As String = String.Format("subItem{0}", j.ToString())

I am trying to create a dynamic dropdown after a dropdown has been selested (in asp.net vb)
For example: I have a dropdown question that asks: What brand of car do you drive (Toyota, Ford, Honda, Nissan, Chevrolet)
When the brand is selected I want another dropdown to appear under it with new chocies
For example: If Nissan is chosen, the second dropdown will be populated (from the database) with (Altima, Maxima, etc...)
And in some cases I would like a text box to appear, but If I can figure out the dropdown portion, I am sure I can figure out the textbox.

What Im trying to do is create a function that sees how many items Im wanting to add, then add each item to the combo box, without me having to add each item individually. Basically its to save space coding, and make my code easier to follow.
An example of what Ive got is:
Dim option_one As String = "Inches"
Dim option_two As String = "Feet"
Dim option_three As String = "cm"
Dim option_four As String = "mm"
[code]....
So the function would go instead of all those add items, and it would just say Call ItemFunction() or something like that.

I have a SQL database which I'm running a query against to return a list of names - eg using "select names from table"I would like to add all of these names to an array so I can use them later. To do this I would need to use a dynamic array as the number of names returned could be anything.Apart from first running "select count(names) from table", getting a value and then Redim'ing the array on the count is there another method I can use.I've seen there's a dataset row.count? Can I somehow use this?
connection.Open()
reader = command.ExecuteReader()
While reader.Read()

I need to dynamically create some sort of 'table' on my form. It should look like:
PIC1 INTEGER1 TIME1
PIC2 INTEGER2 TIME2
PIC3 INTEGER3 TIME3
On top of that it should look like a table and have gridlines between the 'cells' containing the picture/data, which makes it even more difficult for me. Before, control arrays were quite simple in VB6, but I've been searching for 1,5 hours now and I can't figure out how to do this in VB.NET 2010. Any idea how to tackle this the most efficiently?

I need to create some serial port controlls manually. My program reads through a config file, and it if comes across an entry called COMPORT then I need to create a contol to talk to this port. The entries in the ini file might be
COMPORT=COM1
COMPORT=COM3
COMPORT=COM7
So here is my problem! I'd like to create the variable control name with part of the com port number, so I can always refer back to it.
EG.
Dim strVar as sring = "COM1"
Dim CName+strVar As New System.IO.Ports.SerialPort

Wish you all are doing fine at the start of a new year
I am a beginner developer. I am developing a website. I have few divs which made up dragable boxes enhanced by jquery portlets. see the codes below.(html).
<div class="portlet">
<div class="portlet-header"> Category A </div>
<div class="portlet-content">
[Code]....
I also have a stored procedure from the database developer that return the list of categories. Depending on the user selection, the list of categories can vary.
So i have to dynamically create those Boxes. Each categories returned by the SP should replace Category A, Category B, and so on. As i can't know the number of categories returned by the SP i just hard coded those divs. My question is simply how ? How can i achieve this?
I have to be using VB.net in VS 2010. The database is in SQL server 2008.

I've a DLL assembly reading a variable, "GalleryID", from an XML file. I can't modify the assembly, so I am wondering if I can make the XML element value dynamic? For example, to get this value from a querystring or any other scenario without changing the assembly.[code]This is an ASP.NET website that has multiple users. When a user logs in and open the gallery.aspx page it will show the user's own gallery. This scenario is not working now since the gallery module shows one gallery (Galleryid=2) to all users according to its setting in Settings.xml file. How can I pass galleryid in querystring -- gallery.aspx?galleryid=5 and inject it to Settings.xml file?

I have developed a vb.net app with MS access as back end db.when i installed exe on client's machine, it gives error that it couldn't find the db file on client's machine, even though i have changed the connection string in app.config file after the installation. What i have found out is that when a dataset is created at development time and whatever the address is at that time , that is the address it looks for at client's machine.

I am trying to create an autocomplete textbox using jquery which will be bound to SQL database. I also want to place a dropdownlist on the page so based on initial selection autocomplete textbox will retrieve data from different tables. It's an ASP.NET 2.0 page and code behind is VB.NET. I have AJAX autocomplete working but it matches only first characters and its not as robust as jquery. Can anyone share a sample code that will retrieve search data from SQL and also give me directions on how to make the table name dynamic?
