I am trying to write a program in vb.net which uses AWS's Web Service to change the permissions for a security group in EC2.
I have installed the AWS SDK for .Net.
I found an example of how to do this in C# on http://awsdocs.s3.amazonaws.com/sdk-net/latest/aws-sdk-net-dg.pdf (page 39).
I have managed to translate the code into vb, but I am getting an error concerning the 2nd of the following two lines:
Dim ec2Client As New AmazonEC2Client(credentials, config)
Dim ingressResponse As AuthorizeSecurityGroupIngressResponse = ec2Client.AuthorizeSecurityGroupIngress(ingressRequest)
The error Visual Studio gives for this second line is:
Amazon.EC2.AmazonEC2Client.Friend Function AuthorizeSecurityGroupIngress(request As Amazon.EC2.Model.AuthorizeSecurityGroupIngressRequest) As Amazon.EC2.Model.AuthorizeSecurityGroupIngressResponse' is not accessible in this context because it is 'Friend'.
I have read everything I can find on the topic and have posted this on the AWS forum but nothing is helping me.
All other AWS references within Visual Studio seem fine, so I am beginning to wonder whether this is a bug in the SDK for .NET.
I am desperate for help as I cannot call the AWS web-service without this line.
Any suggestions would be greatly appreciated!
In the line:
Dim ingressResponse As AuthorizeSecurityGroupIngressResponse() = ec2Client.AuthorizeSecurityGroupIngress(ingressRequest)
You are storing the response of AuthorizeSecurityGroupIngress in a function() rather than a variable.
Change AuthorizeSecurityGroupIngressResponse() into AuthorizeSecurityGroupIngressResponse.
I think that it is a bug; however, I have found a way to get around it by using AuthorizeSecurityGroupIngressAsync instead of AuthorizeSecurityGroupIngress:
Dim ec2Client As New AmazonEC2Client(credentials, config)
Dim ingressResponse As System.Threading.Tasks.Task(Of AuthorizeSecurityGroupIngressResponse) = ec2Client.AuthorizeSecurityGroupIngressAsync(ingressRequest)

I have a SharePoint test website (Azure SharePoint farm) which contains several image files and some document templates. I want to download the images to my local drive. I anticipate looping through a list of URLs, e.g. http://mySharePointSite/Sites/Images/Image01.png and downloading each in turn. I've tried URLDownloadToFile which works great if I put the images on a regular website but I'm unable to get past Windows Security with this approach.
I had a go at creating an InternetExplorer.Application Object (late binding) and can view my images but am unable to download them. Was trying ieApp.ExecWB but this throws a Run Time Error that seems insurmountable.
I've also tried WinHTTP.WinHTTPrequest.5.1 (StackOverflow 22051960) but, while that looked promising it returned a short string "???????" instead of an image.
I'm really hoping for a VBA solution and am wondering if Impersonate User might provide options, or if there are other options (excluding using SendKeys). Sadly I'm pushing the limits of my VBA knowledge and could really use some guidance.
Is it possible to download from share point from VBA?
If so how, am I missing something simple?
I can paste code, but really I'm not sure I have anything worth sharing. If this is not possible or unreliable in VBA then would be possible with VB.Net (my next steepest learning curve)?
Hope this helps someone. I ended up using Visual Studio to create a dll in VB.Net that I can call from VBA. VB.Net dll requires references to microsoft.sharepoint.client
And the VBA code requires a reference to the resulting dll.
Imports Microsoft.SharePoint.Client
Module Module1
Sub Main()
Dim myContext As Microsoft.SharePoint.Client.ClientContext
myContext = New ClientContext("http://TestSP-a.cloudapp.net/sites/Images/")
Dim myCredentials As New System.Net.NetworkCredential
'' I'm accessing a website from the outside so there
'' are no credentials on my PC. If on the same NW I
'' assume I can use the line below instead of the
'' 3 lines that follow.
'myCredentials = System.Net.CredentialCache.DefaultNetworkCredentials
myCredentials.UserName = "UserNameForSharePoint"
myCredentials.Password = "PassWordForSharePoint"
myCredentials.Domain = "" ' <-- Leave Blank
Dim mySiteSP As New Uri("http://TestSP-a.cloudapp.net/sites/Images/Image1.png")
Dim myTemp As String = "C:\temp\test.png"
My.Computer.Network.DownloadFile(mySiteSP, myTemp, myCredentials, True, 600000I, False)
End Sub
End Module
I'm trying to get containers for my app settings and files and i found this code in Microsoft Website
Windows.Storage.ApplicationDataContainer localSettings = Windows.Storage.ApplicationData.Current.LocalSettings;
Windows.Storage.ApplicationDataContainer localFolder = Windows.Storage.ApplicationData.Current.LocalFolder;
but when i paste it to my code it give me an Error
anyone know what is the error ? how can i solve it ?
LocalFolder isn't a storage container, its a storage folder. Wouldn't something like this work better?
Windows.Storage.ApplicationDataContainer localSettings = Windows.Storage.ApplicationData.Current.LocalSettings;
Windows.Storage.StorageFolder localFolder = Windows.Storage.ApplicationData.Current.LocalFolder;
The property you are accessing returns an object of type StorageFolder (as documented on the same MS webpage where you found an incorrect example). So, just change the type of localFolder as appropriate.
Don't trust examples, they often contain errors for the first several years after publishing. Also, learn to read and understand error messages. The error you posted explicitly says what's wrong and how to fix it.
I hope anyone can help me.
My plan was to connect to Microsoft Azure with my iPhone application. I don't have any experiences using http requests with Objective C yet. So I searched all day long on how to use Azure with Objective C...
I found out that one should use OData to create a proxy class which should help to connect to Azure (http://www.interoperabilitybridges.com/projects/odata-client-for-objective-c-%28ios-macos%29).
So I tried configuring like it says in OData's user guide. But I don't understand how to create a proxy class: I tried to compile the odatagen.xcodeproj but I got a Range or index out of bounds error.
However I typed this in Terminal:
./odatagen /uri=https://{serviceNamespace}.serverbus.windows.net /out= users/xyz/Documents[...] /auth=acs /u=myusername /p=mypassword /at=https://{serviceNamespace}.serverbus.windows.net /sn={serviceNamespace} /ups=no
(Of course replacing {serviceNamespace} with the name of my service namespace etc.)
Did I get all those parameters right? I get an mystical error saying fileRange Error While moving xslt file: (null)... :-(
Or am I totally wrong and connecting my app with Azure works with different tools?
I'm sure you could get it working with what you're doing, but Microsoft have done a lot of the hard work for you. Take a look at the Windows Azure Toolkit for iOS on git hub, it's probably the best place to start.
I'm using Silverlight 4 OOB & elevated trust.
I need to get all the filenames on specific directory & populate an object List(Of String)
The compiler throws an error "Method not found" on .Getfiles() method.
Dim files() As String = System.IO.Directory.Getfiles(Path) 'this line is failing..
Help!
The GetFiles is marked as "Security Critical" and therefore cannot be used from your code.
You will want to use the EnumerateFiles method instead. GetFiles is sooo .NET 1.0, EnumerateFiles is much slicker, even in the full framework you'd want avoid this older Array returning API if you can.
As far as I know you cannot directly access the whole hard drive using Silverlight OOB.
Quoting from Silverlight site:
When running in a trusted environment, you can access only files in
user folders, specifically the MyDocuments, MyMusic, MyPictures, and
MyVideos folders. Although this makes sense from a security point of
view, it’s limiting. You want to enable the user to drag their data
from any location. As it stands right now, if you try to drop a file
from a location other than stated above, Silverlight will throw a
security error.
Please refer to this link for details on how to work with the hard drive using Silverlight OOB:

I am a .NET student and currently we are learning about Application Domains.
We were given the following example code (for .NET 3.5). As expected, it throws a SecurityException. Note: TestApp.exe is added as a reference in the project.
Dim file As String = "TestApp.exe"
Dim hostEvidence As Object() = {New Zone(SecurityZone.Internet)}
Dim appDomainEvidence As Evidence = New Evidence(hostEvidence, Nothing)
Dim d As AppDomain = AppDomain.CreateDomain("MyDomain", appDomainEvidence)
d.ExecuteAssembly(file)
When trying to run this in VS2010 under .NET 4.0 I run into a problem.
First it shows a warning
'Public Sub New(hostEvidence() As Object, assemblyEvidence() As Object)' is obsolete: 'This constructor is obsolete. Please use the constructor which takes arrays of EvidenceBase instead.'.
I change the type of hostEvidence to EvidenceBase() and the warning is gone.
However, when trying to run the application it gives an error.
This method implicitly uses CAS policy, which has been obsoleted by the .NET Framework. In order to enable CAS policy for compatibility reasons, please use the NetFx40_LegacySecurityPolicy configuration switch. Please see http://go.microsoft.com/fwlink/?LinkID=155570 for more information.
I have viewed the page, followed the link to How to: Run Partially Trusted Code in a Sandbox and read http://blogs.msdn.com/shawnfa/archive/2009/05/27/coding-with-security-policy-in-net-4-0-implicit-uses-of-cas-policy.aspx but I'm having trouble understanding all of this.
The code example on MSDN is quite big compared to what I currently have, so any help with changing my code so it works without adding other stuff, will be very appreciated.
As it says in the link you provided, .NET is no longer supporting the policy portion of the code access security framework, as of version 4.0.
In other words, your lesson is about .NET 3.5 and does not pertain to the 4.0 framework. The solution is to revert to your original code and configure your project to target the 3.5 framework (you can still use Visual Studio 2010).
