I made a little console application to help me with remapping client certificates to my webserver. However, when I try to run the application it is giving me an error of:
Unhandled exception at 0x00920309 in CertMapping.exe: 0xC0000005: Access violation reading location 0x00000000.
It's a pretty basic console app:
Imports Microsoft.Web.Administration
Module Module1
Sub main(ByVal cmdArgs() As String)
Dim WebSite As String = Nothing
Dim UserName As String = Nothing
Dim Password As String = Nothing
Dim Base64EncodedCertData As String = Nothing
Dim switch As String, arg As String
For Each Str As String In cmdArgs
switch = Split(Str, ":").First
arg = Split(Str, ":").Last
Select Case switch
Case "/Web"
WebSite = arg
Case "/User"
UserName = arg
Case "/Pwd"
Password = arg
Case "/Cert"
If arg = "mySecretCode" Then
Base64EncodedCertData = "ServerCertGoesHere"
Else
Base64EncodedCertData = arg
End If
End Select

I'm developing small app using visual studio 2013, VB to scan range of IP addresses in same network
my app will take IP's and return
Ping status (True or False)
Computer Name
MAC address
and all OK
my question is if i need to get remote computer windows (xp or 7 or 8 )
using IP address or computer name how i can do that?
Dim osVer As String
osVer = System.Environment.OSVersion.ToString
Finally I used system management as below
(after importing System.Management)
I used two Functions
first one to connect remote Computer then collect data
Private Function tryConnect(SystemName As String)
Try
Dim ComputerConnection As New System.Management.ConnectionOptions
' to add user name and password
'ComputerConnection.Username = "UserName"
'ComputerConnection.Password = "Password"
With ComputerConnection
.Impersonation = System.Management.ImpersonationLevel.Impersonate
.Authentication = System.Management.AuthenticationLevel.Packet
End With
'connect to WMI
MyMgtScope = New System.Management.ManagementScope("\\" & SystemName & "\root\CIMV2", ComputerConnection)
MyMgtScope.Connect()
Return MyMgtScope.IsConnected
Catch ex As Exception
Return False
End Try
End Function

I'm using GeckoFX 29.0 with AutoJSContext and when i launch my app, it gives me the following error :

I understand that i must initialize Xpcom before calling AutoJS but in my code XPcom(xullrunner) is initialize before the Sub named "GeckoFxError"
Sub New()
InitializeComponent()
Gecko.Xpcom.Initialize(Environment.CurrentDirectory + "/xulrunner")

Thanks for your help and i think it's easy to solve but i haven't found any solution in more than one hour
Put your Gecko.Xpcom.Initialize(Environment.CurrentDirectory + "/xulrunner") before calling InitializeComponent() and it should work.
I'm trying to find some code that I can use in vb.net 4.0 to query the our exchange 2013 server. It will be housed on a web server and that server does not have outlook installed on it. Looks like I need to use EWS to do this but I've tried a lot of code snippets and still have not been able to figure this out. The distribution list i'm trying to query is in the public folders/Office Contacts. I've tried examples that use nesting to go through the public folder seen there is no deep traversal but I'm not doing something right there. I am not posting code because i'm not sure it would help. I was hoping someone has already done this and would give me some nuggest of info to get me started.
The examples I've found do not query the distribution list but rather add to it. It's not that I haven't tried... I've got hundreds of lines of code from different places that I've tried and tried to learn from.. but i'm not getting it done. Anyway.. help would be great.
Sorry about not posting any code.. I actually thought I deleted this post.. but i'll post the code that is now working for me. This code does a query to the public folder and then grabs some of the data about each contact in that contact list.

I just got it working so I haven't started to refine it yet.. but hopefully this will help someone else as I didn't find any code that did this
In parseing a web page, the following function works fine when I run it locally:
Public Function GetElement(ByVal IHTMLDOMNode As mshtml.IHTMLDOMNode, ByVal InnerText As String) As mshtml.IHTMLElement
Dim objIHTMLAnchorElement As mshtml.HTMLAnchorElementClass
Dim s As String
s = Microsoft.VisualBasic.Information.TypeName(IHTMLDOMNode)
If s = "HTMLAnchorElementClass" Then
t = GetType(mshtml.HTMLAnchorElementClass)
objIHTMLAnchorElement = Marshal.CreateWrapperOfType(IHTMLDOMNode, t)
If objIHTMLAnchorElement.innerText.Trim() = InnerText Then
Return objIHTMLAnchorElement
End If
End if
' code that loks at child nodes and makes a recursive call
When it is deployed at the web host provider however, the same input results in the string s being "HTMLAnchorElement" instead of "HTMLAnchorElementClass".
If I change the code to
Dim objIHTMLAnchorElement As mshtml.HTMLAnchorElement
Dim s As String
s = Microsoft.VisualBasic.Information.TypeName(IHTMLDOMNode)
If s = "HTMLAnchorElement" Then
t = GetType(mshtml.HTMLAnchorElement)
objIHTMLAnchorElement = Marshal.CreateWrapperOfType(IHTMLDOMNode, t)
If objIHTMLAnchorElement.innerText.Trim() = InnerText Then
Return objIHTMLAnchorElement
End If
End if
I get an "The type must be __ComObject or be derived from __ComObject" error
What may be the cause of this behavior and/or what can I do about it?
Without understanding why (someone please shed light on this), the following works:
Dim objIHTMLAnchorElement As mshtml.HTMLAnchorElement
Dim s As String
s = Microsoft.VisualBasic.Information.TypeName(IHTMLDOMNode)
If s = "HTMLAnchorElement" Then
t = GetType(mshtml.HTMLAnchorElementClass)
objIHTMLAnchorElement = Marshal.CreateWrapperOfType(IHTMLDOMNode, t)
If objIHTMLAnchorElement.innerText.Trim() = InnerText Then
Return objIHTMLAnchorElement
End If

Ok so this works fine in production, qa, and localhost until we moved it to an Azure VM. From the VM we can go use a browser to get to the https://maps.google.com/maps/api/geocode/xml?sensor=false&address= URL. but when another page calls the getgeocode function the results are always blank meaning the rest api call failed in some way.
I don't think its the domain key restrictions because a) im not using a key in this call and b) i set my google api key to any domain to test it.
EDIT: I have tried using another service with the same result. It works in dev and on local machines but not on the Azure VMs. What I do not understand is how the REST apis are accessible via the browser, but return nothing when called from code.
Any ideas?
Explicitly creating a web client and loading that into the xml document has fixed this issue for me.
