Hi Dave,
Thanks for your reply. Your response seemed to suggest on using limited SQL accounts if I read it correctly. Is there any reason you didn't mention Active Directory accounts and groups ??
I appreciate this topic is massive. I'd appreciate if you knew of any good resources (online or book based) that covered this topic well from all view points.
I need a balance between security and functionality. I really want to limit the customers a contractor can see to just them, and if I have numerous contractors it's too hard to use numerous hard coded accounts.

Possible, but a PITA to administer. Imagine a company with 10,000 users...

There's a couple of ways of doing this. Either your app checks a directory group for membership in some kind of "Contrator" group, or if SQL Windows Integrated security is turned on, SQL Server security can be setup to use that group instead of an SQL User Account.
Any of the SQL Server Security books would cover this. Just go to Amazon and search for "SQL Server Security". Believe it or not, the SQL Server Programming books don't get into this stuff very deep at all.

I sure wouldn't want to do that. 10,000+ users, yikes

I have! 30,000 desktops and 300,000+ users.

I already mentioned this is a cross post of his. I kind of got snapped at about Active Directory and he didn't even mention using it.

Dear friends,
I have a problem that i want to depackage a computer package.
Situation is as under.
i have following tables
1. Casing (CasingID, Model, Status, Notes)
2. Motherboard (MotherboardID, Model, Status, Notes)
3. Keyboard (KeyboardID, Model, Status, Notes)
4. Mouse (MouseID, Model, Status, Notes)
5. Status (StatusID, Status)
(values) 1, Packaged
2, Available
3, Damaged
etc.etc.etc....
6. Package (CasingID, MotherboardID, KeyboardID, MouseID)
now i have a form (PACKAGE FORM) on which there is a listview with following columns
ITEMID ITEM-TYPE SPECS
1 Keyborad multimedia...
2 Motherboard 16-bit architecture...
3 Mouse wirless....
4 Keyboard non multimedia...
5 Casing ATX power supply...
OK, now try to understand care fully that before saving a package, A function (i have written to change the status which checks every time in the packge) moves table to table and changes the status of items to "PACKAGED". this function is working properly.
Problem is that when i reload the package to remove some items from the package
then how i can keep in mind that what items are removed from the package because i have to again change their status to "AVAILABLE"
i have two solutions already with me
1. when ever i remove some item from listview, then immediately change the status in the reference table
2. Add an array to the project which save my removed items and in the end a fuction should go to all the reference tables to change the status
have you any other shortest solution for that.... please

Guys, I badly need your help on this. My thesis drives me nuts with this program. I have encountered a few here and there errors with our proposed system. I'll be enumerating them here. I really need help here, since the pre-defense will be on the 28th of the month...
BTW, just for info, I am a ComSci student
My program is on SQL coding and uses VB .NET 2003
As for database, I use Microsoft Access
Errors
* When I try to add user information, I generate this error
Data type mismatch in criteria expression
Simply put, it's when I try to add values to the database for student
information like student number, last name, course, etc.
* I see this error when I code this
Dim f3dg1 as List
Well, the f3dg1 is user defined, i just referred to it as mnemonics to form3
which has a datagrid. What the error in here is the keyword List, which VB "doesn't seem to recognize"
* Ok, here's the last. Here is the program segment for my datagrid.
I can't display column headers in my datagrid (gave me countless sleepless nights... duh) which is why my query (well, actually just a masterlist) don't work.
Try
Dim f As New List
Dim ja As OleDbDataAdapter
Dim ds As DataSet
Dim dv As DataView
Dim dg As New DataGrid
Dim str As String
Dim t As New DataGridTableStyle
Dim d As DataRow
Dim f3dgc1 As DataGridTextBoxColumn
Dim f3dgc2 As DataGridTextBoxColumn
Dim f3dgc3 As DataGridTextBoxColumn
f.f3p1.Controls.Clear()
f.f3p1.Controls.Add(dg)
openconn()
str = "Select * from books"
f.show()
ja = New OleDbDataAdapter(str, dbconn)
f.f3p1.controls.add(dg)
dg.Height = 584
dg.Width = 320
ds = New DataSet
ds.Clear()
ja.Fill(ds, "books")
dg.TableStyles.Add(t)
t.MappingName = "books"
f3dgc1.MappingName = "bookid"
f3dgc1.HeaderText = "Book ID"
f3dgc1.Width = "100"
f3dgc2.MappingName = "bname"
f3dgc2.HeaderText = "Book Name"
f3dgc2.Width = "300"
f3dgc3.MappingName = "aname"
f3dgc3.HeaderText = "Author Name"
f3dgc3.Width = "200"
If Me.BindingContext(ds, "books").Count > 0 Then
With dg
.Dock = DockStyle.Fill
.DataSource = ds
.DataMember = "books"
.Refresh()
End With
Else
f.close()
dg.Visible = False
MsgBox("no record found", MsgBoxStyle.Exclamation)
End If
dg.Refresh()
dg.DataSource = ds
dg.DataMember = "books"
dg.ReadOnly = True
closeconn()
Catch ex As Exception
MsgBox(ex.Message)
End Try
I can send you the program as a whole if you want, if these confuses you.
Please, I don't want to see a grade of 5.0 on my thesis subject 
Hoping for quick responses.

What data is the database expecting and what are you trying to put in there. You may want to show the database table structure along with your code you provided

You've got a ton of problems with this code. I'd rewrite it to simplify it, but you have to do it yourself. If anyone else rewrote the code and you turned it in, the coding style would suddenly change and you'd get put under a microscope for cheating.

We can't answer this question because you've supplied no information on the structure of the database or the code that is used to add this to the database. From the error, you tried to do something like put a number into a field expecting a string of characters.

What is "List"?? From your code, "List" better be the name of a form you created in your project. It's also a very bad name to use because in .NET 2.0 (VS 2005), List is now a collection class.

You do NOT have to create three seperate variables for TextBoxColumns. You would actually be better off putting in the code to setup the DGV in a seperate method. And your current variable names suck, badly. A CompSci student writing a thesis paper should already know the meaning of 'self documenting code' and how it applies to variable names.

Hello,
You may use the following VB Script to record audio:
Dim rec
Set rec = CreateObject("AudioCtl.AudioRecord.1")
'Select sound device 0
rec.DeviceIndex = 0
'Set output file
rec.SetOutputFileName "1.mp3"
'Start record with given parameters, record mp3 audio
rec.StartRecord 2, 11025
'Record for 10 secs
WScript.Sleep 10000
'Stop Record
rec.StopRecord
Thanks,
James

Hi,
I thought you might be interested in this[^] article, from the Coding4Fun blog

Guys how can i get my computer name using visual basic 6.. thnkz..
|
|
|
|
|
use this api
Private Declare Function GetComputerName Lib "kernel32" Alias "GetComputerNameA" (ByVal lpBuffer As String, nSize As Long) As Long
|
|
|
|
|
Or you can use the Windows Scripting Host to get it.
Dim WshNetwork As Object
Set WshNetwork = CreateObject("WScript.WshNetwork")
MsgBox WshNetwork.ComputerName

I did try and search for a meaning, but what does the # do on statements like:-
V = 10000#
Andy.
|
|
|
|
|
The appended character specifies that the literal value should be treated as a certain datatype instead of the type that's infered by the number. For example, 10000# says that the number should be treated as a Double type instead of an Integer. 10000@ should be treated as a Decimal type. The documentation on it (VB.NET) is here[^].
