Hello,

if an PrinterSettings-Instance is not set-up correctly (for example just
by using the default-constructor), then the "ToString()"_method will
throw an exception!



Unhandled Exception: System.ArgumentException: The value '0' is not a
valid value for the enum 'Duplex'.

at System.ComponentModel.EnumConverter.ConvertTo(ITypeDescriptorContext
context, CultureInfo culture, Object value, Type destinationType)
at System.ComponentModel.TypeConverter.ConvertToString(Object value)
at System.Drawing.Printing.PrinterSettings.ToString()
at PrinterSettingsBug_CS.Class1.Main(String[] args)


Here is a simple example to reproduce the problem:

<code>
namespace PrinterSettingsBug_CS
{
class Class1
{
[System.STAThread]
static void Main(string[] args)
{
System.Drawing.Printing.PrinterSettings ps = new
System.Drawing.Printing.PrinterSettings();

System.Console.WriteLine(ps.ToString()); // <===== Exception *****
}
}
}
</code>

Do you need a memory-leak finder ?

Hi Jochen,

What is the version of your VS.NET and .Net Framework?
I have tried your code, but no exception generated.
My VS.net IDE is 2003 Version 7.1.3088, .Net Framework is 1.1
Version 1.1.4322

Hi ,

Have you overrided the ToString method of PrinterSettings?
If not, have you tried this code on other machines?

It is strange that I have tried your code on my 3 colleagues' machine and
all work well. (their VS.net also version 2003 Framework 1.1)

Best regards,
Beste
