How can I use new objects and features with the wrapper component.
Summary
The wrapper component is a COM ActiveX that can be used in environments like vd6 and c++6. We have implements .tlb files which can be added in the project's references and can give your application functionalities of the new component. For more information and implementations you can contact us for more details.
Exported tlb files :
VectorDraw.Serialize.tlb
VectorDraw.Render.tlb
VectorDraw.Professional.tlb
VectorDraw.Geometry.tlb
VectorDraw.Actions.tlb
VdrawPro5.tlb
vdrawi5.tlb
vdPropertyGrid.tlb
VdProControl.tlb
Solution
The following code samples implement the wrapper component where with the use of a button we add a vdMtext object which is a completely new object that is implemented in our new libraries and was not present in version 5. For this implementation we have imported VectorDraw.Geometry.tlb ,VectorDraw.Professional.tlb and also vdrawi5.tlb
