<div dir="ltr"><div dir="ltr"><div>Hello,<br><br>I successfully managed to run the WriterDemo example and to connect to the Libre Office from my application. <br>The differences between the .Net Core API and the API used for .Net Framework are astonishing. <br><br>Could you tell me if there is an example of how to get Libre Office version if .Net? I have code which worked with the .net framework, but now the code, listed below, does not work:<br><br><br></div><blockquote style="margin:0 0 0 40px;border:none;padding:0px"><div> Any[] VerRequest = new Any[1];</div></blockquote><div><br></div><blockquote style="margin:0 0 0 40px;border:none;padding:0px"><div> VerRequest[0] = new Any(typeof(PropertyValue), new PropertyValue()</div></blockquote><blockquote style="margin:0 0 0 40px;border:none;padding:0px"><div> {</div></blockquote><blockquote style="margin:0 0 0 40px;border:none;padding:0px"><blockquote style="margin:0 0 0 40px;border:none;padding:0px"><div> Name = "nodepath",</div></blockquote><blockquote style="margin:0 0 0 40px;border:none;padding:0px"><div> Value = new Any("/org.openoffice.Setup/Product")</div></blockquote></blockquote><blockquote style="margin:0 0 0 40px;border:none;padding:0px"><div> });</div></blockquote><div><br></div><blockquote style="margin:0 0 0 40px;border:none;padding:0px"><div> XMultiServiceFactory ConfProvider = m_HnComponentContext.getServiceManager().query<XMultiServiceFactory>();</div><div> if (ConfProvider != null)</div><div> {</div></blockquote><blockquote style="margin:0 0 0 40px;border:none;padding:0px"><blockquote style="margin:0 0 0 40px;border:none;padding:0px"><div> XNameAccess ConfAccess = (XNameAccess)ConfProvider.createInstanceWithArguments("com.sun.star.configuration.ConfigurationAccess", VerRequest);</div></blockquote><blockquote style="margin:0 0 0 40px;border:none;padding:0px"><div> if (ConfAccess != null)</div></blockquote><blockquote style="margin:0 0 0 40px;border:none;padding:0px"><div> {</div></blockquote></blockquote><blockquote style="margin:0 0 0 40px;border:none;padding:0px"><blockquote style="margin:0 0 0 40px;border:none;padding:0px"><blockquote style="margin:0 0 0 40px;border:none;padding:0px"><div> return ConfAccess.getByName("ooSetupVersion").Value as string;</div></blockquote></blockquote></blockquote><blockquote style="margin:0 0 0 40px;border:none;padding:0px"><blockquote style="margin:0 0 0 40px;border:none;padding:0px"><div> }</div></blockquote></blockquote><blockquote style="margin:0 0 0 40px;border:none;padding:0px"><div> }</div></blockquote><div><br>Besides, there are another couple of issues regarding the SDK.
