My Goal: Want to show HTML in Slide which I dynamically inject into a Master Presentation.
What I've achieved So far: Converted Html to OpenXML (or WordML to be more specific) then Embedded a word object into the PowerPoint and then analyzed the structure via OpenXML SDK Productivity Tool, It has created embeddings folder which contains the document I've selected, The view which I see when I open presentation is basically an Image which is in /ppt/media/image.emf.
Now I've dynamically replaced the contents of embedded docx but how can I generate its image so that I can update the view as well?
Or is there a pain free solution?
NOTE: For WINFORMS C#
OK, I didn't go through the pain description you wrote in your query I believe you have shed a lot of sweat to make it work, here I am sharing the pain free solution(at least it worked for me) and I believe it should work for you too.
Create a class as below: (I have taken this solution partially from some other SO, sorry don't remember the source)
Usage Explained below :
using PowerPoint = Microsoft.Office.Interop.PowerPoint;
var oPowerPoint = new PowerPoint.Application(); oPowerPoint.Visible = Microsoft.Office.Core.MsoTriState.msoTrue;
I had a requirement to paste the content on the active slide so I used the below code, your logic could be different depending on your need you can ignore the below code line
var activeSlide = (PowerPoint.Slide)oPowerPoint.ActiveWindow.View.Slide;
Feed your HTML content to the below method
HtmlFragment.CopyToClipboard(HTML CONTENT WILL COME HERE);
Below code will paste the HTML into the active slide
oPowerPoint.ActiveWindow.View.PasteSpecial();
I hope you managed to find something about your issue.
A bit late, but for future people who might come here.
This is for the HTML -> PPT part.
PowerPoint.Presentation presentation; presentation = ppApp.Presentations.Open(configuration.PPTTExportedFile, MsoTriState.msoFalse, MsoTriState.msoTrue, MsoTriState.msoTrue); foreach (PowerPoint.Slide slide in presentation.Slides) { foreach (PowerPoint.Shape shape in slide.Shapes) { File.WriteAllText(temporaryFilePath, html); WebsiteToImage websiteToImage = new WebsiteToImage(temporaryFilePath, @"New picture path"); websiteToImage.Generate(); slide.Shapes.AddPicture(@"picture path", MsoTriState.msoTrue, MsoTriState.msoTrue, oldshapeleft, oldshapetop, oldshapewidth, oldshapeheight); fileToDelete.Add(temporaryFilePath); fileToDelete.Add(@""dont forget to remove tmp files"); } }
Convert webpage to image from ASP.NET
If you want to do any object manipulation in Word/Excel/PowerPoint, I suggest to work with
Console.Write("AlternativeText: "); Console.WriteLine(shape.AlternativeText);
Because if you save in your original file an AlternativeText in your object, you can access it fast and you can even change the PATH into a simple variable.
And if you want for example to export a HTML table, do an image from it and change the AlternativeText in order to access it easier later, while giving it an appropriate name that you can access with a 3rd software tool, because PowerPoint doesn't support HTML Tags
Next to do:
File.Copy(WordTemplateFile, WordExportedFile, true);
Why you want to change the original? Just make a copy, and keep it as a template which you can change at any moment while creating a new changed version from it.( good for reports )
AlternativeText is very useful if you plan to work with.
For your replacement, you might want to use NetOffice/Microsoft Office libraries.
foreach (NetOffice.WordApi.InlineShape s in docWord.InlineShapes) { if (s.Type==NetOffice.WordApi.Enums.WdInlineShapeType.wdInlineShapePicture && s.AlternativeText.Contains("any pattern you are looking for")) { s.Range.InsertFile(); } }
You loop through all your file and check if something fits your pattern.
Good luck.
