I am using Request.IsSecureConnection to check for SSL and redirecting where appropriate. When running my asp.net website on Rackspace's cloud, the server is running behind an SSL cluster, so IsSecureConnection will always return false. The same goes for checking whether the url contains "https://", always false, checking the port, etc. So the website gets stuck in big redirect loop.[code]...

Is there a cloud app api available for developing on Visual Basic [2008 or 2010]
View 5 RepliesI want a tool to create database applications. I think that the Microsoft product for this is Visual Basic. I would like to ask:
1) Why Visual Basic is better than Delphi ( from Borland )?
2) Where can I see the Versions and Prices?
3) Visual Basic allows to put applications on the Cloud? How this works? In which Cloud services works?
4) Which database can be accessed directly - without having to install third- party components - from Visual Basic? Which of these databases works on the Cloud?
5) Does Visual Basic allows connections to Microsoft Office and/or OpenOffice?
6) Where can I find a version to test it?
I would like to ask : how can i make to support the cloud technology.
Do i have to first find a server that provides cloud services ? Or does the user provide his own custom credentials and server somehow ?
Also, what .NET technology is there for cloud services ? Azure ?
Do you know any good examples / website for that ?
If i develop for Azure will the same code run also with Amazon web services ?
I have been en-charged of creating some apps using the cloud. I only have experience programming windows apps (vb.net) Do you guys have any code samples of cloud apps in VB.NET? If not, do you know where I can find this?What about documentation for creating vb.net cloud apps?
View 3 RepliesI'm looking to move all my code into the cloud using some sort of source control service. It must first be able to integrate with Visual Studio 2008 and 2010, and possibly other environments. Meaning something that's fairly popular among different development environments. The only source control I'm familiar with is VSS, but I think it's time to move away from that. I also prefer a free service. I know that there are only code repository services that are free, but I just don't know how that integrates with Visual Studio and source control.
View 28 RepliesI have a Azure worker role that needs to use the cache in AppFabric. When run locally (Win7x64,VS2010) pointing at the cache in the cloud, it works fine.When I deploy the same package to the cloud (again pointing at the same cache), it produces the following exception:
Message: The type initializer for 'Microsoft.ApplicationServer.Caching.DataCacheClientLogManager' threw an exception.
Exception Type: TypeInitializationException
StackTrace: Microsoft.ApplicationServer.Caching.DataCacheClientLogManager.Initialize(DataCacheLogSink logSink)
at Microsoft.ApplicationServer.Caching.DataCacheFactoryConfiguration.Initialize(String clientName)
at CommunicationRole.CacheUtil.GetCache()
Having looked at the code, this is happening when this line of code is hit:
Dim configuration As New DataCacheFactoryConfiguration()
Nothing runs after this line is hit. As I've said, the configs between local and cloud are the same. I use the cache with the credentials as a session state provider in a web deployment so I believe the cache and access to it are good.My build machine has the November 2011 release of the Azure SDK, and Azure AppFabric SDK 1.5 installed.
The method to get the cache is as follows:
Imports System.IO
Imports Microsoft.WindowsAzure
Imports Microsoft.WindowsAzure.ServiceRuntime

I looked at several questions/answers posted already such as this one on a planar polygon but could not find one that explains results in 3D such as the one shown in this paper and this one on "point cloud skeletonization through Laplacian-Based Contraction" where this quadratic equation comes back in both.
View 1 RepliesI have the following problem. I have some project written in Visual Basic (not Visual Basic .NET but simple Visual Basic - sic!). I can compile it and generate a dll. Then inside my web application I add reference to this dll library. When I run my web application hosted in default Visual Studio server, everything is fine and I can debug my Visual Basic project. However, when I host my web application in IIS then I can't.Code does not stop in my breakpoint. My asp.net catch the exception when I try to execute some method from the mentioned library which is something like:
Unable to cast COM object of type 'xxx' to interface type 'yyy'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{4C2875B5-3265-306B-9C74-1BEC98986B1A}' failed due to the following error: Error loading type library/DLL.

I have a class SELF that is hosted by a couple different classes. Basically, the hosting class HOST calls a method in SELF. SELF is passed HOST as an argument in the constructor, so SELF can call methods in HOST. In normal situations, a call to HOST will do something minor, then return so that SELF can continue. However, for one particular type of HOST, one of the calls from SELF to HOST will cause HOST to call SELF, and so on ad infinitum. A classic, though convoluted, case of recursion. Once again, this is only going to happen for one type of HOST. For other types of HOST, that particular call will not cause HOST to call SELF, so there will be no recursion. Nonetheless, there is no getting around it in one case.
I can see two means to decouple the recursion, and I am wondering which one (or a third) would work best:
1) Add a timer into that particular HOST so that the call from SELF that would trigger the recursion would actually just start the timer in HOST, then return. When the timer ticks, HOST can call SELF. The recursion is broken because the call to SELF is done on the timer event, and not when SELF called HOST.
2) As it happens, HOST makes the first call to SELF in a background thread, which means I don't really need to worry whether this thread blocks or not. Therefore, I could have this background thread spawn a second background thread to make the call to SELF, then have the initial HOST thread JOIN on the second thread. This means that the initial thread will block until the second thread finishes. Meanwhile, the second thread will call HOST, and the HOST won't call back to SELF, it will just return like all the other HOST objects would do. This will allow the second thread to run to completion. When the second thread completes, the first thread will take over and call SELF again on a new second thread. Therefore, the recursion is broken because the secondary thread will always run to completion, and the primary thread will wait for the secondary thread to complete, then call it again.
I tend to prefer the second option, because the first option involves a pause of some length (the minimum for a timer, which is pretty small), while the second doesn't, but the first option is actually a little easier to implement.
I have a WCF Service (with installer) that I have built and installed in Windows Services. Opened up Admin Tools, Services, and started the service without a problem. So now I'm beginning a new project (a simple Windows forms app). I want to consume my new WCF, but have no idea how. I can't seem to add a reference / add a service reference to it.

View 1 RepliesI followed an example to add a custom control (multicolumnCombobox) to my datagridview.[code]Ok, this is fine and dandy, for it adds the custom control to column 2 and row X of that loop.... Now, when I actually use the control for lets say row 0, how do I get the row 0 cell 2 value to be the same as the custom control??I have no way to communicate between the custom control and the datagridview cell.
View 4 RepliesI have myself a self-hosted WCF server setup, which serves a clientaccesspolicy.xml and an index.htm which is just points to my xap (accessible via app.xap).
I'm currently serving them via the following code:
Public Function GetPolicy() As System.IO.Stream Implements IClientAccessPolicy.GetPolicy
WebOperationContext.Current.OutgoingResponse.ContentType = "application/xml"
Return New IO.MemoryStream(IO.File.ReadAllBytes("Server Files/ClientAccessPolicy.xml"))
End Function
Public Function GetIndex() As IO.Stream Implements ISilverlightServer.GetIndex
[Code] .....
It works, does the job I'm after. However, I don't think this streams the xap properly, and I know it's a streaming type. If this isn't streaming it properly, how should I stream it? (The endpoint that the XAP and index.htm files are coming through has a webHttpBinding binding). Is it being streamed properly? Or should I make some changes?

Is it possible to view client transaction requests and host response in a self hosted console window?
Front end client sends request to service
Service console displays requested data in console window and forwards to listening server
Server responds with data
Response is displayed in console window
I guess it would be displaying the traces in the console window.
I am working on a simple form builder which hosts "live" .NET objects as well as performing its own drawing for guidelines (grid), object selection etc. Things are going well but as you see below, the custom painting is not exactly optimal since it always paints behind the hosted controls.
How can I modify my painting logic to draw "on top" of all hosted controls?

i have a Windows service that is hosting a WCF service through net.tcp and this is working great. I have also created a WCF service application. I am trying to add the net.tcp service reference to the service application. Then I add it to the GAC that goes ok but if I try to RegAsm the WCF service application to allow it to be called from Server.CreateObject I get the error:
Warning: Type library exporter encountered a type that derives from a
generic class and is not marked as
[ClassInterface(ClassInterfaceType.None)]. Class interfaces cannot be
exposed for such types. Consider marking the type with
[ClassInterface(ClassInterfaceType.None)] and exposing an explicit
interface as the default interface to COM using the
ComDefaultInterface attribute.
It does not work. I have tried to call it through a class library but this does not work either as the end point is not set correctly.
