Hi,
I have one question related to the visualstylebackcolor property of buttons. When I put one button directly on the form and set that property to false , it works fine but when I put the same button in panel it show a button like its visualstylebackcolor property is true even if the property window is showing it false. 
How to solve this problem ?
Thanks,
Dan

Does anybody know a way to dump the password hashes of the Windows Operating System (Primarily Windows XP, but compatibility would be good)?
Also is there anyway to access the HKLM root on a limited account, I badly need to know to get my program to work correctly.

There isn't one. The hash only works one way. You cannot reverse the hash to get the password out. The only way to figure out what it is is to hash a test password and compare that hash to the stored hash. If it's a match, you found the password. Considering the shear number of number, character and letter combinations, you're looking at testing billions of passwords to guess the correct ones.
There are tools out there that do just this. Google for "L0ftcrack".

No. The registry's HKEY_LOCAL_MACHINE key requires admin permissions to get write access to it.

Use Linux to make a copy of the C:\WINDOWS\system32\config\sam file then use lOphtcrack.
You might could use impersonation[^] to access the registry.

No there isn't, hashes are one way. The purpose of a secured cryptographic hash is to make it be something that cannot be worked backwards into the original password.

Hiii
I send a sample of code that use the Access Database (Test.mdb from C and that contain Table1 ( "Prodct" and "Supplier") fields.
Dim myConnection As New OleDbConnection()
dim oDataAdapter as dataAdapter
Dim oDataTable as DataTable
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
myconnection=new oledbconnection("Provider=Microsoft.Jet.OLEDB.4.0; Data Source=C:\Test.Mdb")
oDataAdapter = New OleDbDataAdapter("Select * From Table1", myConnection)
oDataTable=New DataTable
oDataAdapter.Fill(oDataTable)
ListBox1.DataSource = oDataTable
ListBox1.ValueMember = "product"
end sub
Private Sub ListBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ListBox1.SelectedIndexChanged
dim sProduct as string=ListBox1.SelectedItem.ToString()
if not isNothing (sproduct) then
oDataAdapter = New OleDbDataAdapter("Select Supplier From Table1 where Product=" & sProduct & ", myConnection)
oDataTable=New DataTable
oDataAdapter.Fill(oDataTable)
ListBox2.DataSource = oDataTable
ListBox2.ValueMember = "Supplier"
end if
End Sub
may be it helps you.
Thanx

Hi,
You need to implment the parent-child relationship between the two tables to get the desired results. You may try the following code snippet:
---------------------------------------------------------------------------------------------------
BEGIN CODE
Dim dc As OleDbConnection
Dim connstr As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source = C:\Nwind.mdb;"
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim da As OleDbDataAdapter
Dim dt As DataTable
Dim dv As DataView
dc = New OleDbConnection(connstr)
da = New OleDbDataAdapter("Select * from Products", dc)
dt = New DataTable
da.Fill(dt)
dv = New DataView(dt)
Me.ListBox1.DataSource = dv
End Sub
Private Sub ListBox1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ListBox1.SelectedIndexChanged
Dim SupplierIDString = Me.C1Combo1.Columns("SupplierID").Text.ToString()
Dim da As OleDbDataAdapter
Dim dt As DataTable
Dim dv As DataView
dc = New OleDbConnection(connstr)
da = New OleDbDataAdapter("Select * from Supplier where SupplierID = '" + SupplierID+ "'", dc)
dt = New DataTable
da.Fill(dt)
dv = New DataView(dt)
Me.ListBox2.DataSource = dv
End Sub
END CODE
---------------------------------------------------------------------------------------------------
Hope this helps .

When I build my project, the debug version builds fine but the release version does not. No files appear in the Release folder within the bin directory, although, the file path set in the project settings is correct.
Any ideas?
|
|
|
|
|
Are you getting errors when you build in release mode? If so, what errors are you getting?
In the project settings, are you sure you are looking at the Release configuration when checking the build output path?
Without more info, it's hard to know what to suggest. But maybe this will help you think of another option to try.

hi,
can anyone help me how to make this code little easier
Dim a1,a2,a3,a4,a5,a6,a7 as byte
a1 = Convert.ToByte(ListBox3.Items(0))
a2 = Convert.ToByte(ListBox3.Items(1))
a3 = Convert.ToByte(ListBox3.Items(2))
a4 = Convert.ToByte(ListBox3.Items(3))
a5 = Convert.ToByte(ListBox3.Items(4))
a6 = Convert.ToByte(ListBox3.Items(5))
a7 = Convert.ToByte(ListBox3.Items(6))
i'm now have confusing about array..
please anyone can guide me if have more than 7 statement..

Make it an array of 7 items, called a, then assign them in a loop.

Arrays are zero based, so the index gets different from your current names:
Dim a(6) as Byte
For i As Integer = 0 to 6
a(i) = Convert.ToByte(ListBox3.Items(i))
Next
Despite everything, the person most likely to be fooling you next is yourself.

Yeah, I'd have done that, but I was pretty sure my VB would not compile...

Why do you think that?

Because if I did it off the top of my head, I don't know VB that well. I am about to 5 you BTW, I can't believe how many good answers get 1 votes now.
