    <p>I got a problem with this function i use to retrieve the product key from my computer.</p> <pre><code> Public Function GetProductKey(ByVal KeyPath As String, ByVal ValueName As String) As String Dim HexBuf As Object = My.Computer.Registry.GetValue(KeyPath, ValueName, 0) If HexBuf Is Nothing Then Return "N/A" Dim tmp As String = String.Empty For l As Integer = LBound(CType(HexBuf, Array)) To UBound(CType(HexBuf, Array)) tmp = tmp &amp; " " &amp; Hex(CByte(AscW(HexBuf.ToString(1)))) Next Dim StartOffset As Integer = 52 Dim EndOffset As Integer = 67 Dim Digits(24) As String Digits(0) = "B" : Digits(1) = "C" : Digits(2) = "D" : Digits(3) = "F" Digits(4) = "G" : Digits(5) = "H" : Digits(6) = "J" : Digits(7) = "K" Digits(8) = "M" : Digits(9) = "P" : Digits(10) = "Q" : Digits(11) = "R" Digits(12) = "T" : Digits(13) = "V" : Digits(14) = "W" : Digits(15) = "X" Digits(16) = "Y" : Digits(17) = "2" : Digits(18) = "3" : Digits(19) = "4" Digits(20) = "6" : Digits(21) = "7" : Digits(22) = "8" : Digits(23) = "9" Dim dLen As Integer = 29 Dim sLen As Integer = 15 Dim HexDigitalPID(15) As String Dim Des(30) As String Dim tmp2 As String = String.Empty Dim notbuffer As Array = CType(HexBuf, Array) For i = StartOffset To EndOffset HexDigitalPID(i - StartOffset) = notbuffer.GetValue(i).ToString tmp2 = tmp2 &amp; " " &amp; Hex(HexDigitalPID(i - StartOffset)) Next Dim KEYSTRING As String = String.Empty For i As Integer = dLen - 1 To 0 Step -1 If ((i + 1) Mod 6) = 0 Then Des(i) = "-" KEYSTRING = KEYSTRING &amp; "-" Else Dim HN As Integer = 0 For N As Integer = (sLen - 1) To 0 Step -1 Dim Value As Integer = CInt(CLng((HN * 2 ^ 8)) Or CLng(HexDigitalPID(N))) HexDigitalPID(N) = (Value \ 24).ToString HN = (Value Mod 24) Next Des(i) = Digits(HN) KEYSTRING = KEYSTRING &amp; Digits(HN) End If Next Return StrReverse(KEYSTRING) End Function </code></pre> <p>This works well if i compile using x64 or AnyCPU architecture, but if i put x86 (which is what i want) it throws me this error: <a href="http://i.imgur.com/Kfpa7mh.png" rel="nofollow">http://i.imgur.com/Kfpa7mh.png</a></p> <p>It says: "Cannot associate the object type System.Int32 to System.Array" I can't figure out the problem, i can't do a for Next with that arguments? Why this works with x64 and AnyCPU (Still x64 since i got a 64-bit OS) and not x86?</p> <p>Thanks.</p>

    1. COA 32-bit process is redirected to HKLM\Software\Wow6432Node. Which doesn't have the key you are looking for so you now get the default value you pass. 0, an Integer. Compile to AnyCPU or use RegistryKey.OpenBaseKey()

    2. COOh okay, i never stumbled upon regedit calls being redirected, good to know, the thing is, without Compiling to AnyCPU i don't have much choice because i'm not compiling with framework 4.0 + (Which is what that function requires, i'm using 3.0. I'm already searching to find a way without changing the framework too... Thank you.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
