Hi,

We want to replace footer text with current year in newly generated presentation. we have tag in master layout template. we are using following code to replace the year.
shape = FindShape(Slide, “FooterText1”);
if (shape != null)
{
string CurrentYear = Convert.ToString(System.DateTime.Now.Year);
((IAutoShape)shape).Hidden = false;
string str = ((IAutoShape)shape).TextFrame.Text;
if (((IAutoShape)shape).TextFrame.Text != “”)
{
str = !string.IsNullOrEmpty(CurrentYear) ? str.Replace("", CurrentYear) : str.Replace("", “”);
}
((IAutoShape)shape).TextFrame.Text = str;
}
