Hello,
I am using OO to convert PPTs/ODPs to multiple PDFs(generating a pdf per slide
of PPT). I use C# as my programming language. I use this utility from a
windows service to convert PPTs to PDFs and I always make sure that OO is not
called from multiple threads. I have written the following code to do so. but
when ever i try to dispose/terminate some thing(such as xcomponent/xdesktop
object) OO hangs. Please note that this code is working on Windows XP and
problem occurs only to Win2K3. I have looked into bug 79541 as well but this
does not help either because the hang seems like OS specific now.
I have tried using XCloseable's close as well but it also hangs.
The code follows:
XComponent xComponent = null;
XComponentLoader xComponentLoader = null;
try
{
// Get the component Loader for the OO.
xComponentLoader = this.GetComponentLoader();
PropertyValue[] loadProps = new PropertyValue[1];
PropertyValue asHidden = new PropertyValue();
string pptPath = “file:///C:/Test.ppt”;
asHidden.Name = "Hidden";
asHidden.Value = new uno.Any(true);
loadProps[0] = asHidden;
xComponent = xComponentLoader.loadComponentFromURL(pptPath, "_blank", 0,
loadProps);
unoidl.com.sun.star.drawing.XDrawPagesSupplier xDrawPagesSupplier
= (unoidl.com.sun.star.drawing.XDrawPagesSupplier)xComponent;
// XDrawPages inherits from com.sun.star.container.XIndexAccess
unoidl.com.sun.star.drawing.XDrawPages xDrawPages
= xDrawPagesSupplier.getDrawPages();
// get the page count for standard pages
int slideCount = xDrawPages.getCount();
xComponent.dispose();
// The following way is very slow, but i could not find a better
// way to do this.
for (int index = 0; index < slideCount; ++index)
{
pdfOutPath += outFileName + "_" + index + ".pdf";
ooOutPath = ToOOURL(pdfOutPath);
xComponent = xComponentLoader.loadComponentFromURL(pptPath,
"_blank", 0, loadProps);
while (xComponent == null)
{
/Let the component load.
System.Threading.Thread.Sleep(1000);
}
xDrawPagesSupplier = (unoidl.com.sun.star.drawing.XDrawPagesSupplier)
xComponent;
// XDrawPages inherits from com.sun.star.container.XIndexAccess
xDrawPages = xDrawPagesSupplier.getDrawPages();
XStorable xstorable = (XStorable)xComponent;
// Remove all the slides except this one.
for (int removeSlide = slideCount - 1; removeSlide >= 0; --removeSlide)
{
if (removeSlide != index)
{
unoidl.com.sun.star.drawing.XDrawPage removePage
= (unoidl.com.sun.star.drawing.XDrawPage)
xDrawPages.getByIndex(removeSlide).Value;
// Remove the Slide.
xDrawPages.remove(removePage);
}
}
PropertyValue[] props = new PropertyValue[1];
props[0] = new PropertyValue();
props[0].Name = "FilterName";
props[0].Value = new uno.Any(“impress_pdf_export”);
// Store to the given path.
xstorable.storeToURL(ooOutPath, props);
xComponent.dispose(); // This line causes problem
}
}
catch (System.Exception e)
{
string errorStr = "Can't Convert Using Open Office";
}
finally
{
// Quit Open Office.
((XDesktop)xComponentLoader).terminate(); // This line as well.
}
