• Visual C++ CTabCtrl question!

• .NET Development can not create an SQLConnection object

  I am getting an initialization exception when I instantiate SQLConnection. The exception occurs emediately upon creating an instance and does not depend on whether I supply a connection string for the constructor. The odd thing is that I am not getting this error on my development computer, only when I install it on a different computer. The computer giving the exception has .Net 2.0 installed from the redistributable which I downloaded from MS on Thursday. This is happening before I set any properties or do anything else with the new connection. Any ideas Jake Wagner no, I am doing the in ...Show All

• Windows Forms Relaunch of Windows Form

  Hello all I have a small problem. In most cases I can track these things down pretty easy but the complexity of the application after 2 years of development and use has made it hard to track down this last one. The Scenario: Main application runs in the background 1 pixel X 1 Pixel which launches the initial form. When a form is ready to open another form I do the following: BPS.frmMain frmMain = new frmMain(); frmMain.Show(); this .Dispose(); this .Close(); The problem: Due to third party APIs (Written in anything from C++, to VB to me porting from VB to VB.Net and then to C#) being called a form I will dispose ...Show All

• Visual C++ MFC portability

  I wrote a program and compiled it on my laptop(WinXP Home) using MFC in VS 2003.NET and took it to school and tried to run it on one of their computers(WinXP Pro) and I it said it couldn't run because it couldn't find "MFC71.DLL".

• Visual Studio 2008 (Pre-release) Inheritance problem?

  I'm having a problem creating a ServiceHost using two servicecontracts which inherit from the same parent servicecontract. When I try to create the host the following error occurs: ArgumentException: An item with the same key has already been added. My guess is that the creation thinks that both IServiceContract's are two different contracts, which they are not. Is there any solution to this or something I do wrong Creating one contract for both contracts is no option (duo to more inheritance). Call to create the serviceHost: Uri uri = new Uri ( "net.tcp://localhost:8100/LocationService" ); ServiceHost PostalCodeHost = new ServiceHost ...Show All

• Software Development for Windows Vista Rules which reference Activity properties in XOML only workflows

  Has anyone been successful in creating and executing a rule that refers to an property of an activity which was dropped onto the workflow at design time in a XOML only workflow. In our scenario, we have a hosted designer which outputs XOML only workflows. In the designer, we can drop activities on to the surface and reference activity properties from anywhere on the workflow. HOWEVER, if we write a rule (in a policy or condition) which accesses a property on a dropped on activity, the workflow fails validation. It appears that it can't resolve the child activity types at validation time. When creating the workflow with XAML Activatio ...Show All

• Visual C# C# job

  I am applying a C# job Any technical terms I can write in my resume to show my ability in C# ROTFL. Do you think that perhaps if we give you a list of technical terms, they won't ask you questions in the interview that show your lack of knowledge Even if you get the job, if you don't know enough to be asking this question, how long would you expect to keep it My advice for anyone going for a job is *tell the truth*. If you try to lie, they will catch you out, and you will be immediately rejected. I've gone for jobs where I didn't know a lot about the core technologies in use, but I was honest about i ...Show All

• SQL Server Service Broker Dialog and Transport Security

  what is the difference between the Dialog security and the transport security If I disable the dialog security can the messages be sent to the a different SQL server instance. As the transport security will encrypt the messages. If I don't create a certificate to be used by the transport security can the messages be sent to another SQL server instance Can a message be sent to another SQL Server instance without creating a REMOTE Service Binding The difference becomes evident when you think about forwarders. Forwarders are SQL instances that act as intermediate hops on the route a message is deliver ...Show All

• .NET Development Protecting Assemblies

    I'm building an n-tier application with data access, application and UI layers in separate projects and hence separate assemblies. MyProjectUI.dll MyProjectApp.dll MyProjectDataAccess.dll etc... The application will eventually be publicly available for download and installed on end-users machines. How can I protect my middle tier and DAL assemblies from unauthorised access so that a 'clever' user cannot add a reference to one of my separate assemblies and start calling it's public members. Marking members as Internal only works for classes that are 'inside' the same assembly. Any tips or suggestions would be greatly ...Show All
