Have a WPF form to input ploting parameters, all of which is typical to plotting in AutoCAD Select Scale (Custom or 1:1, 1:2, 2:1,1/128 - 1'-0" etc...). Have a special request for a 1:2.1 value for a non-typical output device (which works just fine in the AutoCAD plot dialog and as 0.4762 : 1 Input into Inches and Units variables). This value bombs my program with a 'Conversion from string "Error occured" to type 'Integer' is not valid' Error inside a try catch block.
Have tried several things and I'm petty sure I'm setting all 'PlotSettingsValidator' object settings correctly. So far nothing helps.
Entire procedure is included below (program bombs at: psv.SetStdScale(pltsettings, sc))
Any help you could offer would be highly valued.
