This is impossible to diagnose from our end. An object reference exception is telling you that some object has not been instantiated. Since we are unable to see your code, it's impossible to tell. What you need to do is run your app in debug on a Windows 7 machine and see what the stack trace points you to when your app breaks.

Thanks for answering so quick. I understand the error, but don't understand why the code runs fine, without error, on an xp machine and not on the win 7 machine. I'm just looking for something in general terms that may help me diagnose the problem.

It's impossible to help you without more details.
Any condition on OS version can lead you to different flow in code, and that's just a shot in the dark.
You should probably setup a debug environment to find out why this happens

When I see this type of error, it normally indicates that you have a piece of code that relied on an external component that is 32 bit only, on a 64 bit machine. The test for this is amazingly simple - simply run
corflags /32bBIT+ executablename The app will now be forced to run as a 32 bit app.

Thanks, I'll give that a try.

Aside from the OS difference, are the run-time environments on the different machines the same?

What setting did you use when you compiled the application ? Can you compile it with the target set as "Any CPU" ?
Project/Properties/Build Tab/PlatForm target Drop-down

“How do you know I'm mad?” said Alice.

Just tell me one thing, in which mode did you compile your program?
Debug or Release mode?
Next thing is Object reference problem as others said occurs when you dont create the object of a type.

Hi,
How can I send variables across web pages without using session or cookies? 
Thanks in advance

This is strictly not a C# question, it belongs to ASP.NET forum.
Anyway, try this: Pass them as arguments in the url. E.g. http://www.mysite.com/?arg1=val1&arg2=val2&arg3=val3
Note than on most browsers, the length of the url is limited. Some browsers support only 2000 characters while other support upto 5000. Please use google to do some research.

Psst! You forgot the query marker:
http://www.mysite.com/?arg1=val1&arg2=val2&arg3=val3
Without the '?' it's all a web address.

No bear today? Probably a good idea. The fur gets stuck in my teeth, too...
If you meant ![Beer | [beer]](https://codeproject.freetls.fastly.net/script/Forums/Images/beer.gif) it's spelled with two "e"s.
How much is a "peg" of whisky? It's not a measure I am familiar with. And was it good whisky?

oh oh yes sorry, OG you are speaking to a person who is 2 pegs down  that too large(90 ml each).
Quote: The fur gets stuck in my teeth, too..
hey dont make fun of me...
one peg starts with 30ml( here we call it small).
next is 60 ml( medium).
and finally 90 ml(large).
If you want to become a hero just call the waiter say:
Quote: hey brother, one large please ....
and he will pop up another peg with "90ml". Now look around here and there people stare at you. Now to show off you finish that peg.
But when you come home you vomit like hell (just like me). So the best thing is sit at home watch TV and have your drink. My dad left me a johnnie walker black label. so i had that.

Roughly the same as pub measures here: 1/6 gil == 25ml, so a "large" would be a triple, maybe a little more.

Depends on my mood.
A bit depressed, or angry and it's JD Green Label[^]
For a more reflective mood, it's Glenlivet 1912 (that being the year it was distilled) But I drink that very, very infrequently: the nearest bottle I know of is several hundred miles away, if indeed it still has any content left! And it costs a fortune! Worth it though...
I gave up serious drinking maybe half a dozen years back, and now I might have a glass of wine of an evening, or I might not have anything. Depends on how I feel at the time.

I used the patches: from 20+ a day.
It wasn't easy, but it got easier - and I'm glad I did kick 'em in the end.
But I do know this: the only way to quit is to want to quit more than you want to smoke. If you don't have better mental reasons for quitting than you do for continuing then you won't stop - the real battle isn't the nicotine addiction (though that is pretty rough) it's the mental habit of smoking and the association of smoking with places and actions. So if you smoke when you drink beer - stop drinking beer for a few weeks; drink wine instead and don't create an association between wine and smoking.
"Wanting to quit" is what got me off drinking, smoking and several illegal narcotics... 
Haven't found anything that makes me "want" to give up motorcycles or coffee though!
