[Spire.Presentation]: Index was out of range error

Wed Jun 15, 2022 12:52 pm

I am using the Spire.Office version 5.2.0 (licensed) . The below code is giving the "Index out of range" error while trying to add the html to the shapes

Code: Select all: public void CreatePPTFromHtml(string htmlString, string outputFilename) { Presentation ppt = new Presentation(); ShapeList shapes = ppt.Slides[0].Shapes; try { [color=#FF0000] shapes.AddFromHtml(htmlString);[/color] } catch (Exception ex) { throw ex; } ppt.SaveToFile(outputFilename, FileFormat.Pptx2013); }

Find the details of the exception:
Exception message:
Index was out of range. Must be non-negative and less than the size of the collection. (Parameter 'index')

Stack Trace:
at System.Collections.ArrayList.get_Item(Int32 index)
at spr䚸.ᜀ(Int32 A_0, String A_1, Dictionary`2 A_2)
at spr䚷.ᜂ(ArrayList A_0, Char[] A_1)
at EmbedHtmlString.AppendHtmlString.CreatePPTFromHtml(String htmlString, String outputFilename) in line 8

Any insight on why this error is coming. Thanks in advance.

This is the HTML string used to pass to the method

Code: Select all: string htmlString = @"<HTML><BODY><div><img src='155-200x200.jpg' /><p>The tool is used to streamline and automate the process, improve coordination and communication, increase visibility. The key features of tool are:<br /><ul><li>Identifies tasks ready to be executed</li><li>Plan management in MS project with built-in sync</li><li>Notifies task readiness for team</li><li>Reporting</li></ul></p></div></BODY></HTML>";

Hello,

This HTML is similar in structure to the HTML you provided last time, so we verified it using the fix for the previous issue(SPIREPPT-1963). We found the fix works for this HTML as well. So I will keep you informed as soon as issue SPIREPPT-1963 is completely resolved.
