Visual Basic

You start a conversation with the following lines:
```
	Dim Vdraft As Object
	Set Vdraft = CreateObject("Vdraft.Application")
```
This gives you an object which has the methods and properties listed under IVdraft.
Properties and methods can be accessed using the dot syntax. For example,
```
	Set doc = Vdraft.ActiveDocument
```
This gives you an object with the methods and properties listed under IDocument.
You declare Vdraft object variables As Object. Use the Set syntax to set the variable.
```
	Dim doc As Object
	Set doc = Vdraft.ActiveDocument
```
In some cases an alternate name is listed when there is a naming conflict with Visual Basic keywords, e.g. Closeout instead of Close in the IDocuments interface.
Parameters listed as VARIANT are equivalent to the Variant data type. This means several different types may be valid. For example, Item in the IDocuments interface can accept either an index or a file name.
Parameters listed as BSTR are strings.

Parameters listed in square brackets are optional. The following are all valid:

	Set vec = Vdraft.NewVector(1,2,3)
	Set vec = Vdraft.NewVector(1,2)
	Set vec = Vdraft.NewVector

If you don't explicitly list a property or method for an interface, the default (if any) will be used. The following pairs of lines are equivalent:
```
	Print Vdraft.Name
	Print Vdraft
	Set entity = Entities.Item(1)
	Set entity = Entities(1)
```

C++ using the MFC wrapper classes in Vobjects.cpp

You start a conversation with the following lines:

	#include "Vdraft.h"
	IVdraft Vdraft;
	Vdraft.CreateDispatch("Vdraft.Application", NULL);

Methods are accessed using standard C++ syntax.
```
	Vdraft.Quit();
```
You can retrieve properties by prefixing the name with Get and set them by prefixing with Set.
```
	IDocument doc( Vdraft.GetActiveDocument() );
	vector.Setx(5);
```
The return value of one function can be passed to the constructor of the appropriate class.
```
	IVector vector( line.GetStartPoint() );
```
Parameters listed as VARIANT can often be different data types. Vutil.h defines cVariant, which can be used to conveniently pass VARIANT parameters.
```
	IVector vector( Vdraft.NewVector(cVariant(1), cVariant(2), cVariant(3)) );
```
Parameters listed as BSTR are strings. If you are using MFC, you can pass a CString.
Parameters listed in square brackets are a special type of VARIANT where you don't need to specify a value. Note that you still need to pass the parameter in C++.
```
	IVector vector( Vdraft.NewVector(cVariant(1), cVariant(2), cVariant()) );	// z value empty
```
Default properties and methods have no meaning in C++.
Arrays are numbered starting at 1.
