Autodesk's latest. NET Tutorial (2) (VB. NET)

 
Chapter 2. NET AutoCAD wizard and simple user input
In the first chapter, we use the class library template, so we have to manually add the acdbmdg. dll and acmgd. dll references. In this chapter, we will use the AutoCAD-hosted C # application wizard to create a. NET project, which will automatically add the above two references. Before starting this chapter, you must first install the ObjectARX Wizard (utilsObjARXWizArxWizards. msi in the ObjectARX2006 development kit ).
 
 
 
1) start Visual Studio. NET and select "File> New> Project" (File> New> Project ). In the Create Project dialog box, select Visual Basic Project as the Project type, and then select the "AutoCAD Managed VB Project Application" template. Enter "Lab2" in the project name box and select the project storage location. Click OK. The "AutoCAD Managed VB Application Wizard" dialog box appears. Because we do not need to use Unmanaged code, do not select the "Enable Unmanaged Debugging" item. "Registered Developer Symbol" will use the value you entered when installing the ObjectARX wizard. Click finish to create a project.
2) Let's take a look at the project generated by the wizard. In the solution browser, you will see that acdbmgd and acmgd have been referenced. In the Class. vb file, the "Autodesk. AutoCAD. Runtime" namespace has been imported, and the project uses the name of "Registered Developer Symbol" to name the default public Class. The Wizard also adds a CommandMethod attribute and a function for the class, which is used for AutoCAD commands.
3) in the previous chapter, we use an instance object of the "Autodesk. AutoCAD. EditorInput. Editor" class to output text on the AutoCAD command line. In this chapter, we will use this class to prompt you to select a vertex in the AutoCAD graph, and then display the x, y, and z values of the selected vertex. As in the previous chapter, import the Autodesk. AutoCAD. ApplicationServices and Autodesk. AutoCAD. EditorInput namespaces.
