Hi!
I'm trying to plot a two-page document to PDF and DWF.
The first page should be plotted from model-space, the second page should be
plotted from a paper-space layout I create earlier with
LayoutManager.Current.CreateLayout(name).
Creating the layout works just fine, as well as printing the first page.
When it comes to print the second page, I run into errors.
The line "infoValidatorLegende.Validate(infoLegende);" throws an exception
"eLayoutNotCurrent".
The current layout when I run "Exportieren" is the model-space.
I wouldn't mind setting the paper-space layout to the current layout, but it
doesn't work.
When I try to set the layout to current using
LayoutManager.Current.CurrentLayout = legendeLayoutName;
I get another exception complaining about illegally writing to protected
memory.
Below you'll find my code that does the plotting.
Can anyone please help me?
I need to get this fixed quickly.
Best Regards
