Examples with ComObject com.sun.jna.platform.win32.COM.util.annotation.ComObject used on opensource projects

Example 1 with ComObject

use of com.sun.jna.platform.win32.COM.util.annotation.ComObject 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) {
    assert COMUtils.comIsInitialized() : "COM not initialized";
    ComObject comObectAnnotation = comInterface.getAnnotation(ComObject.class);
    if (null == comObectAnnotation) {
        throw new COMException("createObject: Interface must define a value for either clsId or progId via the ComInterface annotation");
    }
    final GUID guid = this.discoverClsId(comObectAnnotation);
    final PointerByReference ptrDisp = new PointerByReference();
    WinNT.HRESULT hr = OleAuto.INSTANCE.GetActiveObject(guid, null, ptrDisp);
    COMUtils.checkRC(hr);
    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();
    return t;
}

Example 2 with ComObject

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

the class ObjectFactory method discoverClsId.

GUID discoverClsId(ComObject annotation) {
    assert COMUtils.comIsInitialized() : "COM not initialized";
    String clsIdStr = annotation.clsId();
    final String progIdStr = annotation.progId();
    if (null != clsIdStr && !clsIdStr.isEmpty()) {
        return new CLSID(clsIdStr);
    } else if (null != progIdStr && !progIdStr.isEmpty()) {
        final CLSID.ByReference rclsid = new CLSID.ByReference();
        WinNT.HRESULT hr = Ole32.INSTANCE.CLSIDFromProgID(progIdStr, rclsid);
        COMUtils.checkRC(hr);
        return rclsid;
    } else {
        throw new COMException("ComObject must define a value for either clsId or progId");
    }
}

Example 3 with ComObject

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

the class ObjectFactory method createObject.

/**
	 * Creates a new COM object (CoCreateInstance) for the given progId and
	 * returns a ProxyObject for the given interface.
	 */
public <T> T createObject(Class<T> comInterface) {
    assert COMUtils.comIsInitialized() : "COM not initialized";
    ComObject comObectAnnotation = comInterface.getAnnotation(ComObject.class);
    if (null == comObectAnnotation) {
        throw new COMException("createObject: Interface must define a value for either clsId or progId via the ComInterface annotation");
    }
    final GUID guid = this.discoverClsId(comObectAnnotation);
    final PointerByReference ptrDisp = new PointerByReference();
    WinNT.HRESULT hr = Ole32.INSTANCE.CoCreateInstance(guid, null, WTypes.CLSCTX_SERVER, IDispatch.IID_IDISPATCH, ptrDisp);
    COMUtils.checkRC(hr);
    Dispatch d = new Dispatch(ptrDisp.getValue());
    T t = this.createProxy(comInterface, d);
    //CoCreateInstance returns a pointer to COM object with a +1 reference count, so we must drop one
    //Note: the createProxy adds one
    int n = d.Release();
    return t;
