Chevy Mark Sunderland

14y2.5k.NET

Hi there, I hope your appreciated help.

First of all I must say that I am a newbie when it comes to net language.

The platform is C#.

This is my problem.

I need replace the value of DateTime.Now.ToString("dd/mm/yyyy") in all slides of my powerpoint presentation generate in OpenXml.

Now if try my net code the new value of DateTime.Now.ToString("dd/mm/yyyy") is superimposed in the old value of DateTime.Now.ToString("dd/mm/yyyy")

If you have link for similar task, please give it me.

Can you help me? thank you in advance.
Your help would be very appreciated

Thanks for your time and hints.

Chevy, Saw your code, when you are using dd/mm/yyyy you are getting a date. Not sure if you are trying to edit on same date. Alos, no code seen for replacement!

Thanks for your reply.
You have right:

string fileName = @"C:\Inetpub\wwwroot\pptx\ppt1.pptx";
using (PresentationDocument prstDoc = PresentationDocument.Open("ppt1.pptx", true))
{
string newValue = DateTime.Now.ToString("MMMM dd, yyyy");
foreach (SlidePart sPart in prstDoc.PresentationPart.SlideParts)
{
Slide sld = sPart.Slide;
var datePlaceholders = sld.CommonSlideData.ShapeTree.ChildElements.OfType().
Where(s => s.NonVisualShapeProperties.NonVisualDrawingProperties.Name.Value == "Date Placeholder 3");
if (datePlaceholders != null)
{
datePlaceholders.ToList().ForEach(datePlaceholder=>
{
datePlaceholder.InsertNewValue(newValue);
});
}
}
prstDoc.PresentationPart.Presentation.Save();
}
