• .NET Development two versions of .net dramework BinaryFormatter serializing problem...

  Good day, Excuse my beginner's english, please So, my problem: Our applications are developed in Visual Studio 2003 to use framework version 1.1. We use our own authentication/authorizacion system shared between ASP ( called through COM interop ) and ASP.NET ( directly called assembly class from GAC ). The way the applications share authentication information is a string-formatted ticket, made from a class serialized to a string form by BinaryFormatter, then Base64... All has been working fine until framework 2.0 is installed on the computer. Since that time the system doesn't work because of serialization differences between the two vers ...Show All

• Visual Studio Express Editions API Declarations

  How would I go about creating an API declaration I mean in Visual Basic the API declaration for timeGetTime is Private Declare Function timeGetTime Lib "winmm.dll" () As Long and in C# it's: [DllImport("winmm.dll")] private static extern long timeGetTime(); How would I perform the same task in C++ Thanks in advance The API was designed to be used in C/C++. It's the other languages where you have to hack in the API with these weird declarations. First, note that the MSDN help for the APIs write code in C (not C#/VB/Java). Next note at the bottom of the MSDN help it shows something like: Requirement ...Show All

• Software Development for Windows Vista question about load state workflow from xoml file?

  Hi, I am using the following code to load a state machine workflow WorkflowInstance instance = _wfRuntime.CreateWorkflow(new XmlReader("WorkflowTest.xoml") WorkflowTest.xoml is like this <ns0:BaseWorkflow x:Class="Epic.Kiosk.Workflow.WorkflowTest" ...> ... The question I have is the code only works if I remove x:Class="WorkflowTest.WorkflowTest" from the xoml file, otherwise it will error saying "workflow validation error". I guess the reason the validation failes is because "WorkflowTest.WorkflowTest" is not defined any where. My question is what is the bes ...Show All

• .NET Development Is XP SP2 mandatory to run a .NET Framework 2.0 app?

  Hello, I noticed that when I tried to install .NET Framework 2.0 Beta , Win XP SP2 should be installed in order to continue! Will it be also required on the final release of the .NET Framework 2.0 Thanks. http://www.microsoft.com/downloads/details.aspx FamilyID=7abd8c8f-287e-4c7e-9a4a-a4ecff40fc8e&displaylang=en You will need the redist from at least the version it was developed on (an app developed in 2.0 requires it.)  I'm not sure the redist requires SP2 though, doesn't look like it at the page above ...Show All

• Visual Studio 2008 (Pre-release) Hosting WCF in a Windows Service?? "No endpoint listening exception"

  Hello, I'm working on an ASP.NET application that i want to host using WCF using "basicHttpBiniding" . The hosting should be done in a windows service. I've did a test by hosting the service in a console application (instantiating a ServiceHost in a console application project), everything worked fine. The same project is now transferred to be a windows service, i receive an exception "There was no endpoint listening at http://localhost:8000/HelpDesk/HelpDeskService that could accept the message. This could be caused by an incorrect address or SOAP action, among other things." Debugging teh service shows no errors b ...Show All

• SQL Server Using Teradata .NET data provider as data source

  Recently I installed the .NET data provider for Teradata. In a regular C# application I can add the namespace, " using Teradata.Client.Provider; " to connect to this data provider directly without going though ODBC or OLD DB so I know it works. However, when I open Reporting Services (new project -> Business Intelligence Projects) I do not see how to add the Teradata .NET provider. I only see the same standard data types as before. I have searched and I do not see how to add the Teradata .NET provider to the available "Type" list when you click “Add New Data Source” to your report. Thanks! ...Show All

• Visual Studio Tools for Office Word/Excel Designer Error in VSTO 2005

  Last week I received a new machine at work. On Friday, I installed VSTO 2005 (which had been previously installed on my old machine and worked fine) with no problems. I modified and existing Excel project that I was working on and everything worked fine. Yesterday I opened another existing Excel Workbook project. I was able to compile and run the project successfully, but I received an error message when I tried to view the workbook in the VS IDE. The error message was: "Programmatic access to the Microsoft Office Visual Basic for Applications project system could not be enabled. If Microsoft Office Word or Microsoft Excel is runn ...Show All

• .NET Development Now what's wrong?

  <% Set pageCount = Server.CreateObject("MSWC.PageCounter") pageCount.PageHit() %> <p>You are visitor number <% =pageCount.Hits() %> since the last reboot. Any thoughts on how to make this persistant, i.e. survive a reboot. My thought to write to the server disk causes a protection error. You can store the value on disk, or the registry (with the given permissions requirements met) but you will have to be careful about concurrency issues. You can also store in a database where the concurrency problems are solved. BTW. this is a forum focused on Web Services, try ASP.NET forums or search for an ...Show All

• Visual Studio Team System h status oddity

  This seems like a bug to me.  Let's say I have two users (John and Jane) and John has a file checked out in a subdir C:\Proj\Foo\Bar\baz.cs.  Jane then tries to see if any of the files in C:\Proj\Foo\Bar are checked out by other users so she executes: h status . /user:* Hmm it says there are no changes.  However, if she executes: h status /user:* It shows that John is editing the file.  The bummer is if this is a large project and team, the project wide output of "h status /user:*" is likely to be mostly noise.  It seems like if I restricted the query to the local dir "h status . /user:*" that it  ...Show All
