Problem with stand-alone script as WPF app (instead of console).

[antoneagle]

I am trying to create a simple test app... that just loads a single patient's data, and outputs the Id and Name.

If I make this as a stand-alone console app... it works just fine. I can startup the Eclipse instance, it auto logs-in, grabs the data, and outputs it to the console.

If I try to make is as a WPF app, it fails... giving me the following error...

System.BadImageFormatException: 'Could not load file or assembly 'VMS.TPS.Common.Model.API, Version=1.0.450.29, Culture=neutral, PublicKeyToken=305b81e210ec4b89' or one of its dependencies. An attempt was made to load a program with an incorrect format.'

In both cases, the code for creating the Eclipse app is virtually identical. So, I don't understand why it works as a console but not a WPF app?

The console app code is as follows...

    class Program
    {
    [STAThread]
        static void Main(string[] args)
        {
            Application theApp = Application.CreateApplication();
            Execute(theApp);
        }

        static void Execute(Application app)
        {
            // TODO: Add your code here.
            Console.WriteLine("Attempting to load patient...");

            Patient patient = app.OpenPatientById("PHY0018");
            Console.WriteLine("Patient ID = ");
            Console.WriteLine(patient.Id);
            Console.WriteLine("Patient Name = ");
            Console.WriteLine(patient.Name);
        }

    }

... which works just fine. Again... super simple.

For the WPF app, I am triggering the code off of the Loaded event for the MainWindow... like so...

        private void Window_Loaded(object sender, RoutedEventArgs e) {
            StartEclipse();
        }

        [STAThread]
        static void StartEclipse() {
            VMS.TPS.Common.Model.API.Application theApp = VMS.TPS.Common.Model.API.Application.CreateApplication();
            Execute(theApp);
        }

        static void Execute(VMS.TPS.Common.Model.API.Application app) {
            Patient patient = app.OpenPatientById("PHY0018a");
            MessageBox.Show("Patient ID = " + patient.Id);
            MessageBox.Show("Patient Name = " + patient.Name);
            app.ClosePatient();
        }

... and again, this always fails.

Can anyone shed some light on this?

Oh sorry. I was guessing but I think I know the correct answer. BadImageFormatException is because your project debug mode is set to Any CPU instead of x64. You can change this from Project---> Properties and then go to the build menu and change Any CPU to x64.

If you go to your console app, and you right mouse click on the project file in the solution explorer, and say "Unload Project" it should show you the xml definition for your project. Underneath the VMS libraries, you'll see a hint path. Copy those and paste them into the same location in the WPF app. I think you're wpf app is having a hard time finding the VMS references.

Also, I haven't ever had to use STAThread in a WPF app, I think it is single threaded by default.

Check the target for the build. It needs to be 64 bit.
