Getting started using Microsoft Visual C#

Note: This section assumes a simple knowledge of Visual C#, the Microsoft Foundation Classes and C#. For more help, see relevant documentation.

SISCONST.VS

The ActiveX Control constants available to Visual C# are contained in an automatically generated C/C# header file with the .VS extension.

The SISCONST.VS file is created as follows:

  • Run a Cadcorp SIS application that can be customised using GisLink and select the Developer Control Bar.
  • Select the Generate Programming File command (right-button) in the Developer Control Bar.

  • The Generate Programming File dialog will be displayed:

  • Check the SIS Control radio button and choose Visual C# from the drop-down list.
  • Fill in the Filename: field (either by typing a filename or choosing one using the Browse button). The file will typically be called SISCONST.VS but you can choose any name.
  • Press the OK button to automatically generate the file.

Adding the ActiveX Control to a Visual C++ Project

  • In Microsoft Visual Studio select Create a new Project.
  • Now select Windows Forms App > C# and click Next.

  • Name the Project “SISControlTest”.

  • Click Next and select .NET 8.0 for the framework.
  • Click Create to set up the form.
  • Now click on Project > Add Project Reference > COM select SIS Control 9.1 and click OK.

  • NOTE: If you cannot locate this file, select Browse > Program Files > Cadcorp SIS Desktop > SISControl.ocx
  • Select Any CPU > Configuration Manager.
  • Select Active solution platform > New > x64 Ensure both Debug and Release are set to x64.
  • Open View > Toolbox (or press Ctrl + Alt + X).
  • Locate “Cadcorp SIS Control” under the General tab. Drag and drop Cadcorp SIS Control onto the Form.

  • Double click anywhere on the white space within the Form to open “Form1.cs” with some code on it. Add this code snippet within the “private void Form1_Load” method:

    Copy 
    axSis1.LicenceKey = "<your_key_here>";
    axSis1.LicenceSuffix = "<your_suffix>";
    axSis1.SetStr(SisLib.Constants.SIS_OT_SYSTEM, 0, "_SentinelRMSServerList$", "<server_address");
    axSis1.Level = SisLib.Constants.SIS_LEVEL_MODELLER;

     

    • TIP: “axSis1” is the default name for the ActiveX Control used in this example. Ensure you check the properties of SISControl in the form to confirm the name you have used.


  • Press Run/Build or the green play button.

  • You will see a blank screen with co-ordinates and a view which can be controlled using the scrollbars or the scroll button.
