Samples of using the SwissEphNet library - https://github.com/ygrenier/SwissEphNet

SwissEphNet.Samples

Samples of using the SwissEphNet library in different types of .Net projects in particular the loading file mecanism.

All this projects use the SwissEphNet.Samples.Sharedproject that contains the test logic based on the official SweWin project.

Each project implements the ITestProvider for print and load file implementation.

The test use the ITestProvider.LoadFile for update the LoadEventArgs object:

private void SwissEph_OnLoadFile(object sender, LoadFileEventArgs e)
{
    Encoding enc = e.Encoding;
    e.File = Provider.LoadFile(e.FileName, out enc);
    e.Encoding = enc;
    Provider.Debug.WriteLine($"Required file:{e.FileName} => {(e.File != null ? "OK" : "Not found")}");
}

Async context

Unfortunally the SwissEphNet library is not async, and can't be it (too complex to implements).

Fortunally we have a solution: wait the result. But beause the async context can changed the risk is to create an interlock freeze.

An explaination is available on the Loading files wiki page.

Project SwissEphNet.Samples.ConsoleNet40

Console application in .Net 4.0.

The data files are copied in a datas folder.

The Net40TestProvider read the data files from the folder.

Project SwissEphNet.Samples.ConsoleNet46

Console application in .Net 4.6.

Works like the SwissEphNet.Samples.ConsoleNet40 project.

Project SwissEphNet.Samples.WinForms46

WinForms application in .Net 4.6.

This sample has 3 tests:

• Run test : Works like the console samples for the files using the WinFormsTestProvider.
• Run test load async : This test use the WinFormsTestProviderAsync wich simulate an async loading file, but the call is sync
• Run test async: this test use the WinFormsTestProviderAsync wich simulate an async loading file and the test is run in a task so in an async mode

The WinFormsTestProviderAsync make a pause on each loading file to simulate a long time running and see the blocking or non-blocking of the main thread.

A progress bar is displayed to show the test running. In the 2 first cases this progress bar don't move because the test run in the main thread. For the last case, the progress bar is animated that indicates the main thread is not blocked.

Project SwissEphNet.Samples.WPF46

WPF application in .Net 4.6.

Works exactly like the WinForms sample.

Project SwissEphNet.Samples.UWP

Universal Application.

BEWARE: UWP use the NETStandard 1.0 version of the library, so to be compatible the UWP application need the Microsoft.NETCore.UniversalWindowsPlatform at the version >=5.2.2.

This sample run like the WinForms or WPF samples, but it has only two tests because the files are read as async:

• Run test : Works like the Run test load async WPF using the UwpTestProvider.
• Run test async: this test use the UwpTestProvider and is run in a task so in an async mode

Project SwissEphNet.Samples.Universal

Windows 8.1 + WindowsPhone 8.1 applications.

Works like UWP application.

Project SwissEphNet.Samples.Droid

Android (Monodroid) application.

Works like WinForm application.

Beware: the data files are added to the projet as Assets, but the InputStream used to read an asset don't support the get_Position(), so an error is raised while reading the data files. To prevent this problem the DroidTestProvider copy the asset into a MemoryStream. So it could be a problem to use assets has data for a real application because all is loaded in memory.

Project SwissEphNet.Samples.iOS

Because I don't have a Mac computer I can't make a iOS project.
