• .NET Development Which Certificate do I purchase for WSE 3.0 from Verisign

  I am using WSE 3.0 and the usernameToken approach to secure my public webservice. I need to purchase a X.509 certificate to install on the server and then install the public key on the client. This is all working with a certificate I created with MakeCert.exe. When I ring Verisign to purchase a certificate non of the sales reps have any ideas about webservices or WSE. All they try and sell me is SSL. I will need to purchase a "Microsoft Authenticode Code Signing Digital ID" to sign my client download for clickonce. Can anyone tell me what product I should ask for from verisign or equivalent CA. Is the x.509 certificate I am after any different from the code signing ID. I've never purchased one so excuse me if its the same thing ...Show All

• Visual C# Static

  How to indicate to some class to declare a static functions ..interfaces does no support static members.. Thank you Let me get the question straight: do you want a way to enforce a class to implement static methods If that is your question, an abstract baseclass which has virtual static methods should be the solution. Pitty virtual static is not allowed. This post mighthelp you as it provides a workaround. Please note this is a workaround, not a solution: there isn't any (as far as I know)! Quote from that post: " with static methods, you are not really going to achieve polymorphism " ...Show All

• Windows Live Developer Forums Is this executed too fast for Firefox?

  I have an example page here: http://tacticalshadows.com/jstest/maptest4563.htm This works fine and the located area is pinned under internet explorer, but it does not proceed to find the location in firefox. What gives This example doesn't show what I am trying to do in the long run, but shows what is keeping me from doing it. I am trying to in the page load, load a map that has a location pinpointed. The location is something I am passing to the page so when it loads I can just render the map accordingly. If someone has a way to do that for both ie and firefox then I would be interested in seeing how. I just don't understand why IE executes that find fine and firefox botches.

• Visual Studio Team System How do I add a new report to the Project Portal?

  Hello, I've just created a new report and would like to add it to the team project portal. I'd like it to show up just as the "Remaining work" report does. How can I do this Cheers, Chris Ah, I think there is a misunderstanding... I have deployed the report to the report server and I'd like to keep it there. But here is the scenario: My boss is a very busy man and he wants to see the project progress the quick and easy way. We created a report and would like to show it / publish it / deploy it on the sharepoint site in order for him to see the progress using Internet Explorer. Now, there are a couple of other built-in reports already doing this, such as "Remaining work". D ...Show All

• .NET Development Wse 3.0 needs 2.0 Calls?

  Hello, We are building a Web Service that uses WSE 3.0 and a custom UserNameToken Authentication Manager. During the course of development, we discovered the custom autrhthorization manager was not being invoked. Someone who has worked with WSE 2.0 noticed the line of code (documented in a WSE 3.0 sample): ws.RequestSoapContext.Credentials.SetCredentials(new CredentialSet(unt) ); and suggested : ws.RequestSoapContext.Security.Tokens.Add(unt); From his WSE 2.0 experience. The compiler flagged the WSE 2.0 code as obsolete, but it worked and the presences of the UsernameToken (unt) was detetected in the SOAP header and the correct Auth Mgr code was executed. Question: Is this bug in WSE 3.0 ...Show All

• Windows Forms DataGridView and BindingNavigators

  Hello, When I click the Add button on a BindingNavigator (bound to a BindingSource) I cannot get the DefaultValuesNeeded event of a DataGridView to populate a cell with a default value. Has anyone else encountered this issue before Is there a work-around Cheers, sfx1 Hi Ken, Thanks for your reply. Yes, when I click the AddNew button on the BindingNavigator the row is added to the DataGridView, but no default values are supplied to the cell. However, if I just click on the very last row (that is, a new row) of a DataGridView a default value is supplied. Is there a way to keep the BindingNavigator's functionality while inserting default values into a Grid Cheers, sfx1 ...Show All

  Hi, I am making an app that plots out arcs from another source. I have been given or have calculated the Begining angle, the End Angle, the traverse Angle, the Radius, the center point, the start point, the end point.

• Visual Studio Express Editions Query filtering

  Hi, I'm trying to make a search engine to go through an access database, and need to filter a query. When I set the parameter prefix it doesn't register the change and tells me there's a syntax error. When I go back to see what the prefix is, the prefix box is blank. How can I get the parameter prefix to stay changed Also, can I set the parameter to a text box that will search the entire database after pressing a button I haven't been able to get that far yet. Alright, I'm sure I must be almost there. I'm able to search the fields that I want to using a text box, but the only results that I get are the ones that match perfectly, I want to be able to find a record using any word located in the record. ...Show All
