Dim rec As Integer
For row = 0 To 46 - 2
For col = row + 1 To 46 - 1
If fileArray(row, 1) > fileArray(col, 1) Then
For rec = 0 To 1
temp(rec) = fileArray(row, rec)
Next
For rec = 0 To 1
fileArray(row, rec) = fileArray(col, rec)
Next
For rec = 0 To 1
fileArray(col, rec) = temp(rec)

Have you tried single stepping through each line to see what isn't working?

What sorting algorithm is it that you are trying to use?

"Just set the PasswordChar property of your TextBox to *. " i would do that but i carnt as i only mad a form that says click here to log in with a button then i put all the code on that so i carnt load up the for for when coding to do that im not realy bother how the code is as long as it works in some way cus this is for college and they dont care what code we use as long as it works

Why are you choosing a difficult way when you can easily do this with the functionality provided by the .NET Framework otherwise you have to adopt a difficult way by using APIs to get the current key pressed store it into a StringBuidler object assign a * to the inputbox for key pressed and repeat the process to get the work done and I think you should have looked at Rule No. 9 before even creating this thread.

It is considered a bad idea to have plaintext passwords embedded right in your code. I hope you plan on using some crypto algorithm.

Hi,
You can simply use the MaskedTextBox from the toolbox. Then set its password char to "*" .

Hi all,
I am working in vb.net and i am using sql server as back end which is stored on the server.
Client can access the database using his user id and password,
but the problem is that with the same login account the user can login from more than one client machine.
:-OI want that if the client has logined using suppose user id A and password A
then he will be not able to login again using the same user id and password from another client machine.
So how can it possible? will i have to maintain session like Asp.net ?
if yes then how can i maintain session using vb.net
Any idea would be appriciated heartly
Thanks with anticipation![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)

Add a field to your user account table that indicates whether the user is currently logged on.
If a user is logging in and the value in this field is false, set it to true.
If a user is logging in and the value in this field is true, disallow the login.
When the user logs out, set the value in this field back to false.

Hi,
I have an array declared as a structure. The structure has about 7 members (variables).
Is there a way to loop through the array and for each member check if it is null?
like this:
for i= 0 to array(index)
for each object array(index)
if is nothing ...
next
next
Thank you!

As Christian said it is not possible, but a handy method is to make a function called GetNulls() in your structure which returns null members. Now search through the array and get nulls.

Hi
I am using VB.2005 Express edition to develop a application. I can define my issue in parts
- What all Grid Controls are available. Is there only one “Data Grid View” grid control ?
- I wanted to use the grid control to display reports, this report is based on query from database, system state, user types and some more things. My issue is that i am not finding any way how to add data to Data Grid control. The only way i am finding is to link the column with some table. Cant i formulate a row on my own and add it in the grid.
- Is there any other control in which i can on my own formulate the data and display, the way we used to do in VB6 in MsFlexGrid or the Grid control
Regards

You create a DataSet and populate that with data from your database by using a DataApapter. You call the Fill method of the DataAdapter to get the data into the DataSet.
Now you can set the DataGridView.DataSource property to be a Table in your DataSet.
Dim ds As DataSet = New DataSet()
Dim cn As SqlConnection ... ' your connection string here.
cn.Open()
Dim cmd As New SqlCommand("SELECT * FROM TABLE",cn)
Dim da As New SqlDataAdapter(cmd)
da.Fill(ds,"tableName")
cn.Close()
Me.DGV.DataSource = ds.Tables("TableName")
The DataGridView is much more powerfull and usefull that the old MSFlexGrid (especially for bound data) and only takes a little patience to master.
Check for these terms in MSDN, Google or on Code Project for heaps of examples.

In this lotto project i am producing 6 nonrepeating random numberswith one procedure. when i call this to make 6 randomnumbers for 54 week it is giving the same numbers
the code is below
Sub randomNumbers(ByVal num As Integer)
Dim randomNum As New Random
Dim i As Integer
For i = 0 To num
rnd = randomNum.Next(1, 46)
If i = 0 Then
Numbers(i) = rnd
Else
For j As Integer = 0 To i - 1
If Numbers(j) = rnd Then
rnd = randomNum.Next(1, 46)
j = 0
Continue For
End If
Next
Numbers(i) = rnd
End If
Next
End Sub
Sub sorting()
Dim temp As Integer
For i As Integer = 0 To Numbers.Length - 2
For j As Integer = i + 1 To Numbers.Length - 1
If Numbers(j) < Numbers(i) Then
temp = Numbers(i)
Numbers(i) = Numbers(j)
Numbers(j) = temp
End If
Next
Next
End Sub
Private Sub bt56_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles bt56.Click
Dim i As Integer
'Dim num(5) As Integer
Dim ctr As Integer = 0
Me.Label1.Text = ""
For i = 1 To 54
Me.randomNumbers(5)
sorting()
For j As Integer = 0 To 5
fiftysixArray(ctr) = Numbers(j)
Numbers(j) = 0
ctr += 1
Next
Next
End Sub

Hi,
if you don't provide an explicit seed a random number generator will use the current time
as a seed, so everytime you create a new Random (within the same millisecond or so) it
will generate the same sequence.
Solution: insert a Thread.Sleep(1000) and/or provide a variable seed somehow
[added] or avoid creating new Randoms all the time (just have a single static one and
keep using it) [/added].
