Example 1 with ComInterface

use of com.sun.jna.platform.win32.COM.util.annotation.ComInterface in project jna by java-native-access.

the class ObjectFactory method fetchObject.

/**
	 * Gets and existing COM object (GetActiveObject) for the given progId and
	 * returns a ProxyObject for the given interface.
	 */
public <T> T fetchObject(Class<T> comInterface) {

    Dispatch d = new Dispatch(ptrDisp.getValue());
    T t = this.createProxy(comInterface, d);
    //GetActiveObject returns a pointer to COM object with a +1 reference count, so we must drop one
    //Note: the createProxy adds one
    d.Release();
