How to Insert Hyperlinks into OO Writer Documents Using OpenOffice CLI Libraries

On the page https://api.libreoffice.org/examples/examples.html#OLE_examples
there are 2 examples of working with the OpenOffice CLI libraries.
These examples show you how to insert a hyperlink into an OO Calc document. But it is not clear how to insert a hyperlink into an OO Writer document.
Here is the code I wrote:
static void Main(string[] args)
{
try
{
unoidl.com.sun.star.uno.XComponentContext localContext =
uno.util.Bootstrap.bootstrap();
unoidl.com.sun.star.lang.XMultiServiceFactory multiServiceFactory = (unoidl.com.sun.star.lang.XMultiServiceFactory)localContext.
getServiceManager();
XComponentLoader componentLoader = (XComponentLoader)
multiServiceFactory.createInstance("com.sun.star.frame.Desktop");
string fileName = "c:\\Users\\sbe.CSOFT-SPB\\Documents\\OO\\1.odt";
//string fileName = "c:\\Users\\sbe.CSOFT-SPB\\Documents\\OO\\t1.ods";
fileName = #"file:///" + fileName.Replace('\\', '/');
XComponent xComponent = componentLoader.loadComponentFromURL(
fileName, "_blank",
0, new unoidl.com.sun.star.beans.PropertyValue[0]);
if (fileName.ToLower().EndsWith(".odt")) // OO Writer document
{
unoidl.com.sun.star.text.XTextDocument xTextDocument =
(unoidl.com.sun.star.text.XTextDocument)xComponent;
unoidl.com.sun.star.text.XText xText = xTextDocument.getText();
unoidl.com.sun.star.text.XSimpleText xSimpleText =
(unoidl.com.sun.star.text.XSimpleText)xText;
unoidl.com.sun.star.text.XTextCursor xCursor = xSimpleText.createTextCursor();
unoidl.com.sun.star.lang.XMultiServiceFactory xServiceMan =
(unoidl.com.sun.star.lang.XMultiServiceFactory)xTextDocument;
// create a TextFrame (
Object objTextFrame = xServiceMan.createInstance("com.sun.star.text.TextFrame");
unoidl.com.sun.star.text.XTextFrame xTextFrame =
(unoidl.com.sun.star.text.XTextFrame)objTextFrame;
unoidl.com.sun.star.awt.Size aSize = new unoidl.com.sun.star.awt.Size(15000, 400);
((unoidl.com.sun.star.drawing.XShape)xTextFrame).setSize(aSize);
// insert the frame
xText.insertTextContent(xCursor, xTextFrame, false); // it's OK
// create a hyperlink
Object aHyperlinkObj = xServiceMan.createInstance("com.sun.star.text.TextField.URL");
xServiceMan.createInstance("com.sun.star.text.TextField.URL");
unoidl.com.sun.star.beans.XPropertySet xPropSet =
(unoidl.com.sun.star.beans.XPropertySet)aHyperlinkObj;
xPropSet.setPropertyValue(
"URL", new uno.Any("http://www.example.org"));
xPropSet.setPropertyValue(
"Representation", new uno.Any("hyperlink"));
// ... and insert
unoidl.com.sun.star.text.XTextContent xContent =
(unoidl.com.sun.star.text.XTextContent)aHyperlinkObj;
xText.insertTextContent(xCursor, xContent, false); // exception on this statemen
}
else // OO Calc document
{
unoidl.com.sun.star.sheet.XSpreadsheetDocument mxDocument =
(unoidl.com.sun.star.sheet.XSpreadsheetDocument)xComponent;
unoidl.com.sun.star.sheet.XSpreadsheets xSheets = mxDocument.getSheets();
unoidl.com.sun.star.container.XIndexAccess xSheetsIA =
(unoidl.com.sun.star.container.XIndexAccess)xSheets;
unoidl.com.sun.star.sheet.XSpreadsheet xSheet =
(unoidl.com.sun.star.sheet.XSpreadsheet)
xSheetsIA.getByIndex(0).Value;
// create a hyperlink
unoidl.com.sun.star.lang.XMultiServiceFactory xServiceMan =
(unoidl.com.sun.star.lang.XMultiServiceFactory)mxDocument;
Object aHyperlinkObj =
xServiceMan.createInstance("com.sun.star.text.TextField.URL");
unoidl.com.sun.star.beans.XPropertySet xPropSet =
(unoidl.com.sun.star.beans.XPropertySet)aHyperlinkObj;
xPropSet.setPropertyValue(
"URL", new uno.Any("http://www.example.org"));
xPropSet.setPropertyValue(
"Representation", new uno.Any("hyperlink"));
// ... and insert
unoidl.com.sun.star.text.XTextContent xContent =
(unoidl.com.sun.star.text.XTextContent)aHyperlinkObj;
unoidl.com.sun.star.table.XCell хCell = xSheet.getCellByPosition(0, 0);
unoidl.com.sun.star.text.XText xText =
(unoidl.com.sun.star.text.XText)xCell;
unoidl.com.sun.star.text.XTextCursor xTextCursor =
xText.createTextCursor();
xText.insertTextContent(xTextCursor, xContent, false); // it's OK
}
xComponent.dispose();
}
catch (System.Exception e)
{
string message = String.Format("Error.\n{0}\n{1}",
e.Message, e.StackTrace.TrimStart());
Debug.WriteLine(message);
}
}
Inserting a hyperlink into an OO Calc document in this code works, but on the insert statement of a hyperlink into an OO Writer document throws an exception.

In Writer, hyperlinks are not fields, but simply a property of characters.
Basic code:
xCursor.setString("hyperlink")
xCursor.goLeft(9, False)
xCursor.goRight(9, True)
xCursor.HyperLinkURL = "http://www.example.org"
C# CLI code:
xCursor.setString("hyperlink");
xCursor.goLeft(9, false);
xCursor.goRight(9, true);
unoidl.com.sun.star.beans.XPropertySet xPropSet =
(unoidl.com.sun.star.beans.XPropertySet)xCursor;
xPropSet.setPropertyValue("HyperLinkURL", new uno.Any("http://www.example.org"));

Update text layer in psd file in C#

I want to update a specific text layer of psd file (always the same (find with his name)) in C#.
I searched and tested a lot of libraries which didn't working.
Recently, I found this library on GitHub : https://github.com/bizzehdee/System.Drawing.PSD
I downloaded sources, try it and in C#, I can access to my specifid layer, but, I can't update it.
In Layer class, there are differents attributs but I don't control them.
I wan't to know if there is anybody who can test it and help me to understand the library.
I asked the author but his last action is in last year...
I hope you can help me !
Thank you very much.

You can try Aspose.PSD. It supports simple text layer editing and editing text layer by portions: https://docs.aspose.com/display/psdnet/Working+With+Text+Layers
// Load a PSD file as an image and cast it into PsdImage
using (PsdImage psdImage = (PsdImage)Image.Load(dataDir + "layers.psd"))
{
foreach (var layer in psdImage.Layers)
{
if (layer is TextLayer)
{
TextLayer textLayer = layer as TextLayer;
textLayer.UpdateText("test update", new Point(0, 0), 15.0f, Color.Purple);
}
}
psdImage.Save(dataDir + "UpdateTextLayerInPSDFile_out.psd");
}
Example with Text Portions:
string sourceFile = dataDir + "text212.psd";
string outputFile = dataDir + "Output_text212.psd";
using (var img = (PsdImage)Image.Load(sourceFile))
{
TextLayer textLayer = (TextLayer)img.Layers[1];
IText textData = textLayer.TextData;
ITextStyle defaultStyle = textData.ProducePortion().Style;
ITextParagraph defaultParagraph = textData.ProducePortion().Paragraph;
defaultStyle.FillColor = Color.DimGray;
defaultStyle.FontSize = 51;
textData.Items[1].Style.Strikethrough = true;
ITextPortion[] newPortions = textData.ProducePortions(new string[]
{
"E=mc", "2\r", "Bold", "Italic\r",
"Lowercasetext"
},
defaultStyle,
defaultParagraph);
newPortions[0].Style.Underline = true; // edit text style "E=mc"
newPortions[1].Style.FontBaseline = FontBaseline.Superscript; // edit text style "2\r"
newPortions[2].Style.FauxBold = true; // edit text style "Bold"
newPortions[3].Style.FauxItalic = true; // edit text style "Italic\r"
newPortions[3].Style.BaselineShift = -25; // edit text style "Italic\r"
newPortions[4].Style.FontCaps = FontCaps.SmallCaps; // edit text style "Lowercasetext"
foreach (var newPortion in newPortions)
{
textData.AddPortion(newPortion);
}
textData.UpdateLayerData();
img.Save(outputFile);
}

I dont use Aspose because it's not free for use.
All you need is AdobeStandard.COM-component.
Photoshop.Application app = new Photoshop.Application();
Photoshop.Document doc = app.Open(#"test.psd");
for(int i = 1; i <= doc.ArtLayers.Count; i++)
{
string name = doc.ArtLayers[i].Name;
if (name.Equals("Title1"))
{
doc.ArtLayers[i].TextItem.Contents = "Hello World";
}
}

Telerik Report in Asp.Net-Apply Filters in programatically

My Requirement: Apply fillers via c# coding(Not Design) ie, filterer salaries greater than 7000.
I have a class library and a web form in my project.
I am creating the report on class library and display report by using web form.
When I run my application it shows always the unfiltered data.
What i do to get Filtered data in Viewer.
Code:
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
Telerik.Reporting.Filter f1 = new Telerik.Reporting.Filter();
f1.Expression = "= Fields.Salary";
f1.Operator = Telerik.Reporting.FilterOperator.GreaterOrEqual;
f1.Value = "=7000";
EmpReport objEmpReport = new EmpReport(); objEmpReport.Filters.Add(f1);
TypeReportSource rptSource = new TypeReportSource(); rptSource.TypeName = typeof(EmpReport).AssemblyQualifiedName; this.ReportViewer1.ReportSource = rptSource;
}
}

working code:
// ...
using Telerik.Reporting;
using Telerik.Reporting.Processing;
// ...
void ExportToPDF(string reportToExport)
{
// all my reports are in trdx format - detect file type and use unpackage below for trdp files.
string currPath = HttpRuntime.AppDomainAppPath; // get the full path so deserialise works
reportToExport = currPath + #"Reports\" + reportToExport; // add folder and report name to path
UriReportSource uriReportSource = new UriReportSource { Uri = reportToExport }; // compressed to 1 line for brevity
Telerik.Reporting.Report myReport = DeserializeReport(uriReportSource); // extract report from xml format (trdx)
// Filters are client side (use params for server side) Here we work with the report object.
// set meaningful field name and values for your code, maybe even pass in as params to this function...
myReport.Filters.Add("UserId", FilterOperator.Equal , "1231");
var instanceReportSource = new Telerik.Reporting.InstanceReportSource(); // report source
instanceReportSource.ReportDocument = myReport; // Assigning Report object to the InstanceReportSource
// kinda optional, lots of examples just used null instead for deviceInfo

Fill in Word template and save as pdf using openxml and openoffice

I am trying to fill a word document with data from an XML. I am using openXML to fill the document, which works great and save it as .docx. The thing is I have to open Word and save the document as an .odt and then use the OpenOffice SDK to open the .docx and save it as a pdf. When I don't save the .docx as .odt, the formatting is off.
What I need to be able to do is be able to either convert the .docx to .odt or save it originally as .odt.
Here is what I have right now:
static void Main()

xmlDoc.Load("C:\\Cache\\MMcache.xml"); // Load the XML document from the specified file

{
documentText = reader.ReadToEnd();
}
using (StreamWriter writer = new StreamWriter(wordDoc.MainDocumentPart.GetStream(FileMode.Create)))

Just for information I cannot use anything that uses Interop because word will not be installed the machine. I am using OpenXML and OpenOffice

This is what I would try (details below):
1) try Doc format instead of DocX
2) switch to Libre Office and try DocX again
2) use the odf-converter to get a better DocX -> ODT conversion.
More details...
There's something called the odf-conveter (opensource) that can convert DocX->ODT which gives you (typically) more accurate DocX->ODT than Open Office. Take a look at odf-conveter-integrator by OONinja for pre-packaged versions.
Also, Libre Office has DocX support ahead of OpenOffice so you might get a better result simply by switching to Libre Office.
A further option is to start from Doc format rather than DocX. In the OpenOffice world that translates much better to ODT and then to PDF.
Hope that helps.

You may try to use Docxpresso to generate your .odt directly from HTML + CSS code and avoid any conversion issue.
Docxpresso is free for non-commercial use.

Extract powerpoint titles with C#

I have powerponint 97-2003 files(.ppt extension) and I need to extract slide titles programatically using C#.
I have tried using Microsoft.Office.Interop but without success.
I have search with google and as a maximum I have found how to obtain reference to PowerPoint.Slide:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Microsoft.Office.Core;
using PowerPoint = Microsoft.Office.Interop.PowerPoint;
namespace Tester
{
class Program
{
static void Main(string[] args)
{
Microsoft.Office.Interop.PowerPoint.Application presentationApp = new Microsoft.Office.Interop.PowerPoint.Application();
try
{
string pptPath = #"D:\somefile.ppt";
TestReadingTitles(presentationApp, pptPath);
}
finally
{
presentationApp.Quit();
}
}
private static void TestReadingTitles(Microsoft.Office.Interop.PowerPoint.Application presentationApp, string pptPath)
{
presentationApp.Visible = Microsoft.Office.Core.MsoTriState.msoTrue;
Microsoft.Office.Interop.PowerPoint.Presentations presentations = presentationApp.Presentations;
Microsoft.Office.Core.MsoTriState readOnly = Microsoft.Office.Core.MsoTriState.msoTrue;
Microsoft.Office.Core.MsoTriState untitled = Microsoft.Office.Core.MsoTriState.msoTrue;
Microsoft.Office.Core.MsoTriState withWindow = Microsoft.Office.Core.MsoTriState.msoFalse;
Microsoft.Office.Interop.PowerPoint.Presentation presentation = presentations.Open(pptPath, readOnly, untitled, withWindow);
for (int i = 0; i < presentation.Slides.Count; i++)
{
foreach (PowerPoint.Slide slide in presentation.Slides)
{
string slidetitle = ??????????????????;
}
}
}
}
}

You can extract the titles without looping through the shapes.
private static string ExtractSlideTitlefromSlide(Microsoft.Office.Interop.PowerPoint.Slide slide, string defaultValue)
{
if (slide.Shapes.HasTitle == Office.MsoTriState.msoTrue)
{
if (slide.Shapes.Title.TextFrame.HasText == Office.MsoTriState.msoTrue)
{
return slide.Shapes.Title.TextFrame.TextRange.Text;
}
}
return defaultValue;
}

I have no solution for direct extract slide titles from ppt. This is a workarround - first temproaly convert it into pptx and then extract titles using openxml.
For conversion from ppt to pptx I have used Microsoft Interop which I do not like but I have no better solution.

Finally I have found a way to get out powerpoint presentation titles from .ppt file without converting it to .pptx. Here is a solution:
using System;
using System.Collections.Generic;
using Microsoft.Office.Core;
using PowerPoint = Microsoft.Office.Interop.PowerPoint;
namespace Mintra.Publisher.DocumentConverter.Core.Utils
{
class InteropUtility
{
public static IList<string> GetPresentationTitles(string pptPath)
{
IList<string> result = new List<string>();
var presentationApp = new Microsoft.Office.Interop.PowerPoint.Application();
try
{
presentationApp.Visible = Microsoft.Office.Core.MsoTriState.msoTrue;
Microsoft.Office.Interop.PowerPoint.Presentations presentations = presentationApp.Presentations;
var readOnly = Microsoft.Office.Core.MsoTriState.msoTrue;
var untitled = Microsoft.Office.Core.MsoTriState.msoTrue;
var withWindow = Microsoft.Office.Core.MsoTriState.msoFalse;
Microsoft.Office.Interop.PowerPoint.Presentation presentation = presentations.Open(pptPath, readOnly, untitled, withWindow);
int i = 0;
foreach (PowerPoint.Slide slide in presentation.Slides)
{
string defaultTitle = String.Format("Slide {0}", i);
String shapeTitle = ExtractSlideTitlefromShape(slide, defaultTitle);
result.Add(shapeTitle);
}
}
finally
{
presentationApp.Quit();
}
return result;
}
private static string ExtractSlideTitlefromShape(PowerPoint.Slide slide, string defaultValue)
{
PowerPoint.HeadersFooters headersFooters = slide.HeadersFooters;
PowerPoint.Shapes mastershapes = slide.Master.Shapes;
for (int i = 1; i <= slide.Shapes.Count; i++)
{
PowerPoint.Shape shape = slide.Shapes[i];
bool hasTextFrame = shape.HasTextFrame == MsoTriState.msoTrue;
bool isTypePlaceholder = shape.Type.Equals(MsoShapeType.msoPlaceholder);
bool hasTextInTextFrame = shape.TextFrame.HasText == MsoTriState.msoTrue;
bool isTitleShape = shape.Name.ToLower().Contains("title");
if (isTypePlaceholder && hasTextFrame && hasTextInTextFrame && isTitleShape)
{
return shape.TextFrame.TextRange.Text;
}
}
return defaultValue;
}
}
}

Microsoft.Office.Interop.PowerPoint.Application pptApplication = new Microsoft.Office.Interop.PowerPoint.Application();
Microsoft.Office.Interop.PowerPoint.Slides slides;
Microsoft.Office.Interop.PowerPoint._Slide slide;
// Create the Presentation File
Presentation pptPresentation = pptApplication.Presentations.Add(MsoTriState.msoTrue);
for (int i = 0; i < 2; i++)
{
Microsoft.Office.Interop.PowerPoint.CustomLayout customLayout = pptPresentation.SlideMaster.CustomLayouts[Microsoft.Office.Interop.PowerPoint.PpSlideLayout.ppLayoutChartAndText];
// customLayout.t
// Create new Slide
slides = pptPresentation.Slides;
slide = slides.AddSlide(1, customLayout);
slide.Shapes.Title.Top = 0;
slide.Shapes.Title.TextFrame.TextRange.Text = "Welcome!";
All you need is change Welcome text.
