LibreOffice Calc C# SDK: program to insert images into cells, stuck trying to create XGraphic

Background: I'm trying to write a program to insert an image into a cell of a spreadsheet. LibreOffice recently changed how this is done, and all the samples I could find use the old method which no longer works.
Technically I know that you can't "insert" an image into a cell and that such an image is an overlay on a DrawPage that sits on top of the spreadsheet to "decorate" it.
One of the first steps in doing this (the new way) is to create an XGraphic object which contains the image. The process is to create an XGraphicProvider and call it with MediaProperties that specify the image file URL to be loaded. I have a program that is supposed to do this but the resulting XGraphic is null. The LO SDK gives pretty much no information when you do something wrong; it just doesn't work.
Here is the code I have, with all the headers removed:
// addpic
// add picture to spreadsheet - debug version
class OpenOfficeApp {
[STAThread]
static void Main(string[] args) {
bool lreadonly;
string pqfile;
string pqURL;
string pqpic;
pqfile = "file:///D:/Documents/NSexeye/ODS%20File%20Access/"+
"addpix/addpic.ods";
pqpic = "addpic2";
pqURL = pqpic+".jpg";
lreadonly = false;
Console.WriteLine("Using: "+pqfile);
// get the desktop
XComponentContext XCC = uno.util.Bootstrap.bootstrap();
XMultiComponentFactory XMCF =
(XMultiComponentFactory)XCC.getServiceManager();
XMultiServiceFactory XMSF = (XMultiServiceFactory)XCC.getServiceManager();
XComponentLoader XCL =
(XComponentLoader)XMSF.createInstance("com.sun.star.frame.Desktop");
// open the spreadsheet
PropertyValue[] pPV = new PropertyValue[2];
pPV[0] = new PropertyValue();
pPV[0].Name = "Hidden";
pPV[0].Value = new uno.Any(true);
pPV[1] = new PropertyValue();
pPV[1].Name = "ReadOnly";
if (lreadonly) pPV[1].Value = new uno.Any(true);
else pPV[1].Value = new uno.Any(false);
XComponent XCo = XCL.loadComponentFromURL(pqfile,"_blank",0,pPV);
// create graphic object containing image
object oGP = XMCF.createInstanceWithContext(
"com.sun.star.graphic.GraphicProvider",XCC);
if (oGP == null) {
Console.WriteLine("oGP is null. Aborting.");
return;
}
XGraphicProvider XGP = (XGraphicProvider)oGP;
if (XGP == null) {
Console.WriteLine("XGP is null. Aborting.");
return;
}
pPV = new PropertyValue[1];
pPV[0] = new PropertyValue();
pPV[0].Name = "URL";
pPV[0].Value = new uno.Any(pqURL);
Console.WriteLine("Creating XGraphic containing "+pqURL);
XGraphic XG = XGP.queryGraphic(pPV);
// *** XG is null here
if (XG == null) {
Console.WriteLine("XG is null. Aborting.");
return;
}
// ... lots of stuff to be added here
// save and close the spreadsheet
XModifiable XM = (XModifiable)XCo;
XM.setModified(true);
XStorable XSt = (XStorable)XCo;
XSt.store();
XCloseable XCl = (XCloseable)XCo;
XCl.close(true);
// terminate LibreOffice
// *** I want this to not terminate it if something else is open
XDesktop XD = (XDesktop)XCL;
if (XD != null) XD.terminate();
}
}
I get a null for the XGraphic, in the place indicated in the comments. I don't know if the call to create it is failing, or if one of the earlier steps of the process are incorrect.
My goal here, in addition to getting my program working, is to create a sample program showing how to add an image to a Calc spreadsheet cell, and to manipulate such images. There are a fair number of people asking questions about this and none of the examples I've found will work. I think a good working sample will be of value.
I've spent a lot of time searching for information and code samples for this, with nothing that helps. I've tried to find ways to verify the validity of the XGraphicProvider interface with no luck. I've run out of things to try.
I'm hoping someone who knows about the LibreOffice SDK can take a look and maybe see what I'm doing wrong.
Update: I figured out what I was doing wrong: I was passing a bare filename in the "URL" property to XGraphicProvider. It has to be the same format (starting with "file:///") as the spreadsheet's file name specification.
Now I'm stuck with another property problem. The XGraphic has to be specified as a parameter to the GraphicObjectShape's Graphic property, but the setPropertyValue() function requires that it be a uno.Any type. I can't figure out how to specify an interface name like XGraphic as a uno.Any.
Here is the piece of code that won't compile, complaining that it can't convert an XGraphic to a uno.Any, in the first setPropertyValue call:
// set image XGraphic
XPropertySet XPS = (XPropertySet)XS;
XPS.setPropertyValue("Graphic",XG);
XPS.setPropertyValue("Name",new uno.Any(pqpic));
XG is an XGraphic type. Using "new uno.Any(XG)" doesn't work either, giving a similar compiler error.

After trying unsuccessfully for a few hours to get the latest LO SDK up and running, let me offer some untested ideas.
First of all, here is some working Basic code, no doubt similar to what you're translating from. The important line is oShape.Graphic = oProvider.queryGraphic(Props()).
oDoc = ThisComponent
oSheet = oDoc.CurrentController.ActiveSheet
pqURL = "file:///C:/Users/JimK/Desktop/addpic.jpg"
oProvider = createUnoService("com.sun.star.graphic.GraphicProvider")
oShape = oDoc.createInstance("com.sun.star.drawing.GraphicObjectShape")
Dim Props(0) as new com.sun.star.beans.PropertyValue
Props(0).Name= "URL"
Props(0).Value = pqURL
oShape.Graphic = oProvider.queryGraphic(Props())
oCell = oSheet.getCellByPosition(5,5)
oShape.Name = oCell.AbsoluteName + "##" + Props(0).Value
oShape.Anchor = oCell
oSheet.DrawPage.add(oShape)
'Resize
w = oShape.Graphic.Size.Width
h = oShape.Graphic.Size.Height
wcl = oCell.Size.Width
hcl = oCell.Size.Height
If w<>0 and h<>0 then
oCell.String=""
Dim Size as new com.sun.star.awt.Size
Size.Width = wcl
Size.Height = h*wcl/w
If Size.Height > hcl then
Size.Width = hcl*w/h
Size.Height = hcl
Endif
oShape.setSize(Size)
oShape.setPosition(oCell.Position)
erase oShape
Else
oShape.dispose()
Endif
Now, how to translate this to C#? It looks like you may need to explicitly specify the type. In the SDK example, there are calls like this.
xFieldProp.setPropertyValue(
"Orientation",
new uno.Any(
typeof (unoidl.com.sun.star.sheet.DataPilotFieldOrientation),
unoidl.com.sun.star.sheet.DataPilotFieldOrientation.DATA ) );
So in your case, something like this:
XPS.setPropertyValue(
"Graphic"
new uno.Any(
typeof(unoidl.com.sun.star.graphic.XGraphic),
XG));
Alternatively, follow the suggestion here: set GraphicURL, which should load the image and set Graphic for you.

Issues in PrintTitleRows of Synfusion XlsIo

I am using Syncfusion xlsIo version 14.2460.0.26.I have used PrintTitleRows to get the fixed header for every page. But it didn't work.
Here is the code snippet.
sheet1.PageSetup.TopMargin = 0.5;
sheet1.PageSetup.BottomMargin = 0.7;
sheet1.PageSetup.PrintTitleRows = "$6:$6";
sheet1.PageSetup.LeftMargin = 0.5;
sheet1.PageSetup.RightMargin = 0.2;
sheet1.PageSetup.Orientation = ExcelPageOrientation.Portrait;
sheet1.PageSetup.FitToPagesTall = 0;
sheet1.PageSetup.FitToPagesWide = 1;
sheet1.PageSetup.PaperSize = ExcelPaperSize.PaperA4;
Is there any way to get the header in each page.

This could be a document specific issue. So, please log on to Syncfusion support website and create incident regarding this issue for further updates.

Trouble pulling RSS/XML in C# (Forbidden)

I have a snippet of code that has been working fine up until a week ago, and now it errors out and the exception says 403 Forbidden. I have been reading that maybe adding "DefaultCredentials" may help, but I am not sure how to apply that to my code.
I am trying to pull data from: http://na.leagueoflegends.com/en/rss.xml
and my code that was working fine is:
XDocument xmlFile = XDocument.Load(#"http://na.leagueoflegends.com/en/rss.xml");
var LoLtitles = from service in xmlFile.Descendants("item")
select (string)service.Element("title");
var LoLlinks = from service in xmlFile.Descendants("item")
select (string)service.Element("link");
var LoLdescriptions = from service in xmlFile.Descendants("item")
select (string)service.Element("description");
var LoLDates = from service in xmlFile.Descendants("item")
select (string)service.Element("pubDate");
var servicing = LoLdescriptions.ToArray();
for (int i = 0; i < 4; i++)
{
servicing[i] = Regex.Replace(Server.HtmlDecode(servicing[i]), #"<[^>]*>", String.Empty);
}
ViewBag.titles = LoLtitles.ToArray();
ViewBag.links = LoLlinks.ToArray();
ViewBag.descriptions = servicing;
ViewBag.dates = LoLDates.ToArray();
But now the XDocument.Load line is getting a forbidden exception. I can still manually go the .xml's url page and see the file/text, so I am not sure why my program is being denied access all of the sudden...
I have browsed around and I am trying to figure out how to do the Default Credentials approach that people have used for URL/Web requests, however I do not know how to tack that onto XDocument (or an equivalent approach).

Adding Multiple Stencils To Same Visio Sheet

I have C# code that creates a Visio Application instance, then opens some existing stencils so I can get the Shape Masters I need for my drawing. Visio 2013 changed things so I need 2 different stencils open. The issue is that I get 2 drawings open in Visio, 1 per stencil. When I build my document and save it, I can close it but there is still another empty drawing open. I also get an empty blank page in my active document where I am creating the drawing.
Visio.Application va = new Visio.Application();
va .Documents.Add(#"");
Visio.Documents vdocs = va.Documents;
const string templateNameU = "BASFLO_M.VSTX";
const string ConnectorStencilNameU = "BASFLO_M.VSSX";
const string RectangleStencilNameU = "BASIC_U.VSS";
const string stencilNameU = "CONNEC_U.VSSX";
const string connectorMasterNameU = "Dynamic Connector";
const string RectangleMasterNameU = "Rounded Rectangle";
Visio.Master connectorMaster = null;
Visio.Master rectangleMaster = null;
// open the templates we need
Visio.Document vc = vdocs.OpenEx(RectangleStencilNameU, short)Visio.VisOpenSaveArgs.visOpenDocked);
va.Documents.Add(templateNameU);
I have tried closing all the open drawings with:
foreach (Visio.Document d in va.Documents)
{
va.Documents[d.Name].Close();
}
va.ActiveDocument.Close();
but that is messy. The for loop for some reason doesn't close the active document. Is there a way to add multiple stencils to the same document and/or page so I am only working with one page? Is there a way to delete the blank page without resorting to a for loop to get the page name to delete it? I have looked through the API and don't see a way.

It looks like you are creating two documents.. i.e. the first (empty) one with va.Documents.Add("") and then the second one based on the template using va.Documents.Add(templateNameU).
If you don't want the first one, just don't create it.. Means, you can create new document, then open stencils, then draw, then close everything, like this:
var doc = va.Documents.Add(templateNameU)
var stn1 = va.Documents.Open(<first stencil>)
var stn2 = va.Documents.Open(<second stencil>)
// ... do stuff with the doc and then close everything...
doc.Close();
stn1.Close();
stn2.Close();
Am I missing something?
BTW, to get "Dynamic connector" you don't need to open the "Connector Stencil", it contains a specific dynamic connector. To get the default connector, you can just use Application.ConnectorToolDataObject
Also, you can connect shapes using shape.AutoConnect (this will also use the default connector)
Also, you don't need to open the stencil specifically actually. If it is part of the template, it will be opened automatically for you when you create a new drawing based on that template (so you can get them using Application.Documents[].
Maybe helpful? (draw 2 rectangles and connect them):
var doc = va.Documents.Add("BASICD_M.VSTX");
var stencil = va.Documents["BASIC_M.VSSX"];
var rectMaster = stencil.Masters["Rounded Rectangle"];
var rect1 = va.ActivePage.Drop(rectMaster, 1, 1);
var rect2 = va.ActivePage.Drop(rectMaster, 3, 1);
rect1.AutoConnect(rect2, Visio.VisAutoConnectDir.visAutoConnectDirNone);

Creating FedEx Shipping Documnents using FedEx ship service WSDL

I am in the process of integrating with the FedEx international Ship Service. But I am really stuck on one part. I am trying to create a certificate of origin using their test environment. I have followed the xml schema and have come up with the code below
private static void SetCustomInvoice(ProcessShipmentRequest request)
{
request.RequestedShipment.ShippingDocumentSpecification = new ShippingDocumentSpecification();
request.RequestedShipment.ShippingDocumentSpecification.ShippingDocumentTypes = new RequestedShippingDocumentType[1] { new RequestedShippingDocumentType() };
request.RequestedShipment.ShippingDocumentSpecification.ShippingDocumentTypes[0] = RequestedShippingDocumentType.CERTIFICATE_OF_ORIGIN;
request.RequestedShipment.ShippingDocumentSpecification.CertificateOfOrigin = new CertificateOfOriginDetail();
request.RequestedShipment.ShippingDocumentSpecification.CertificateOfOrigin.DocumentFormat = new ShippingDocumentFormat { StockType = ShippingDocumentStockType.STOCK_4X6, ImageType = ShippingDocumentImageType.PDF, ImageTypeSpecified = true, StockTypeSpecified = true };
request.RequestedShipment.SpecialServicesRequested = new ShipmentSpecialServicesRequested();
request.RequestedShipment.SpecialServicesRequested.SpecialServiceTypes = new ShipmentSpecialServiceType[1] { new ShipmentSpecialServiceType() };
request.RequestedShipment.SpecialServicesRequested.SpecialServiceTypes[0] = ShipmentSpecialServiceType.ELECTRONIC_TRADE_DOCUMENTS;
request.RequestedShipment.SpecialServicesRequested.EtdDetail = new EtdDetail();
request.RequestedShipment.SpecialServicesRequested.EtdDetail.RequestedDocumentCopies = new RequestedShippingDocumentType[1] { RequestedShippingDocumentType.CERTIFICATE_OF_ORIGIN };
request.RequestedShipment.SpecialServicesRequested.EtdDetail.DocumentReferences = new UploadDocumentReferenceDetail[1] { new UploadDocumentReferenceDetail() };
request.RequestedShipment.SpecialServicesRequested.EtdDetail.RequestedDocumentCopies[0] = RequestedShippingDocumentType.CERTIFICATE_OF_ORIGIN;
}
But I keep getting an error message back from the web service stating “Invalid Stock Type”. Even though the shipmentDocumentStockType is an enum and I am using one of the values from it. I am still getting this error. Any ideas where I might be going wrong?
Any information will be a great help. I have tried getting in touch with FedEx technical support and they were not really a great help.

This might be a little late for you but just wanted to provide an answer in case someone else might be looking for it.
I was having a similar problem but instead of the Certificate of Origin it was with the Commercial Invoice. Turns out these forms need to be printed on a full 8.5 x 11 page in PDF format, so changing the StockType from STOCK_4x6 to PAPER_LETTER fixed it for me:
From:
request.RequestedShipment.ShippingDocumentSpecification.CertificateOfOrigin.DocumentFormat = new ShippingDocumentFormat { StockType = ShippingDocumentStockType.STOCK_4X6, ImageType = ShippingDocumentImageType.PDF, ImageTypeSpecified = true, StockTypeSpecified = true };
To:
request.RequestedShipment.ShippingDocumentSpecification.CertificateOfOrigin.DocumentFormat = new ShippingDocumentFormat { StockType = ShippingDocumentStockType.PAPER_LETTER, ImageType = ShippingDocumentImageType.PDF, ImageTypeSpecified = true, StockTypeSpecified = true };
Hope this helps
