Are you trying to overcome the System.NullReferenceException Object reference ~~not~~ set to an instance of an object?

for printing file of any type you should be able to read it...

there is no single reader for all types of files...you should check the file type, get appropriate reader...and get it printed.

Keep DotNetting!!

Hi,

for all the file extensions that open a file by double-clicking in Windows Explorer,
the following should be true:

1.
you can OPEN the document by executing the single line of code: Process.Start(filespec);
or a more elaborate variant where you instantiate a Process object, and a ProcessStartInfo
object. If unfamiliar with it, look it up in the documentation.

2.
you can PRINT the document in the same way, this time set
ProcessStartInfo.Verb="PRINT";

You will be facing one problem though: each of the above typically launches a new
process and opens a new window, and these they alive and open even when you are done;
this is not due to the C# code, it is inherent to Windows (try right-clicking on
a document and select either OPEN or PRINT).

Smile | :)

What do you mean the result is same? It happens in the same place? If so, maybe you could help us to help you by posting a relevant code snippet.

I ran into the same issue after upgrading to Windows 7 (and IIS7) A WCF service that was previously working started to get this error.

To fix, I went into the Build properties of my projects (Project/properties/Build Tab) and changed the Platform Targer to "x86". Then the problem was gone.

String Array question..

You can not add element to array. Array has fixed lenght. You can only change any element in array any time:
myArray[0] = "hey bob!";
if you need to add element to array you need to create a new array(with more elements) and copy elements from old arrray to it together with you new elements. But this is pretty much what List<t> does, so if you need to add elements to array often at runtime I would recommend you to use List<t> which also has a method called ToArray which return current state of List<t> as regular array.

No one uses the ArrayList anymore. The generic types in C# 2.0 have rendered it obsolete.

I suggest you check out the Generic List<>[^] type instead.
