I'm using the COM objects from Office 2007 to handle and print ms-office files. I don't have any problems with word and excel documents, but i just can't print Power Point docs.
the code bellow just opens the file send a job to the printer but nothing gets printed
what am i doing wrong? =(
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace Main
{
class PrintPPoint
{
public static void PrintPPointDocument(string filename, int copies, string range)
{
Microsoft.Office.Interop.PowerPoint.Presentation work = null;
Microsoft.Office.Interop.PowerPoint.Application app = new Microsoft.Office.Interop.PowerPoint.ApplicationClass();
Microsoft.Office.Interop.PowerPoint.Presentations presprint = app.Presentations;
//app.Visible = Microsoft.Office.Core.MsoTriState.msoTrue;
work = presprint.Open(filename, Microsoft.Office.Core.MsoTriState.msoCTrue, Microsoft.Office.Core.MsoTriState.msoCTrue, Microsoft.Office.Core.MsoTriState.msoFalse);
work.PrintOptions.PrintInBackground = 0;
work.PrintOptions.ActivePrinter = app.ActivePrinter;
if (range.Equals("0"))
{
work.PrintOut(0, 1, app.ActivePrinter, copies, Microsoft.Office.Core.MsoTriState.msoFalse);
}
else
{
string[] toprintsheet = range.Split(new char[] { ',' });
foreach (string aux in toprintsheet)
{
work.PrintOptions.PrintInBackground = 0;
work.PrintOptions.ActivePrinter = app.ActivePrinter;
if (aux.Contains("-"))
{
int from = 0, to = 0;
string[] SplitRange = aux.Split(new char[] { '-' });
from = Convert.ToInt16(SplitRange[0]);
to = Convert.ToInt16(SplitRange[1]);
work.PrintOut(from, to, app.ActivePrinter, 1, Microsoft.Office.Core.MsoTriState.msoFalse);
}
else
{
work.PrintOut(Convert.ToInt16(aux), Convert.ToInt16(aux), app.ActivePrinter, copies, Microsoft.Office.Core.MsoTriState.msoFalse);
}
}
}
work.Close();
app.Quit();
}
}
}
