C# may not be the best language for this. C++ would b better as you can use inline assembly[^].
If you want to do it in C#, I beleive you'll have to simulate the registers with variables, parse the assembly to get the operators and values, do the math line by line then use the Convert.ToString(value, base) method to convert the output to a binary string.

I'm curious as to whether or not I'd be able to do the following things to list view items:
#1 - Make it so that even when the list view does not have focus, a selected item shows up with the dark blue background color. If you set ListView.HideSelection = false, a selected item without focus will have a grey background, which unfortunately, I haven't been able to figure out how to change.
#2 - Allow selected ListView items to fully select the row. This is not ListView.FullRowSelect, but rather what I mean is... say I have the item "Item1" in the ListView, yet the ListView is wider than that text, the highlighted portion will only cover that text, but will not cover the entire row.
Thanks.

For the first question: Not sure but I think owner drawn items could be the answer.
For the second: If your column(s) is as wide as the listview, the full row should be selected so setting column width helps here.
Hope this helps,
Mika

Ok here you are going outside the design limitations of the control you are using. You have 2 basic choices, find an alternative control that meets your requirements (Infragistics and DevExpress are 2 suppliers) or create your own control.
1. The background colour of the selected item is probably managed by the skin/style windows is using.
2. You are asking it to paint the listviews backgound area according to a control (item) that is not there. As Eric said expand the last subitem to the full width, except then you need to deal with the horizontal scroll bar.

Yeah, I see that it may be a little tough to do this. I ended up taking the ListBox and overriding some of its functionality.

I have two type of objects - Person and PersonEx.
The difference between Person and PersonEx is that PersonEx contains an array of strings, whereas Person does not.
Here's a sample:
class Person
{
public string FirstName;
public string LastName;
public string City;
}
class Details
{
public string attribute1;
public string attribute2;
}
class PersonEx
{
public string FirstName;
public string LastName;
public string City;
public Details[] theDetails;
}
I need to convert from Person to PersonEx and from PersonEx to Person. I don't mind loosing the information in PersonEx.theDetails when converting to Person and leaving PersonEx.theDetails null when converting from a Person is ok.
So far, I have been writing helper methods that do a member-by-member copy of each field (InstanceOfPerson.FirstName = InstanceOfPersonEx.FirstName;). This is not ideal since there are a lot of fields.
I'd like to walk over each type in the source and copy the value to the target so I could write something like this... public TO_TYPE Convert< FROM_TYPE, TO_TYPE >(instanceOfFromType).
I looked into reflection, but that can be painful. I had a similar problem when converting between two types that are identical except that the type names are different - I solved that problem through serialization, but this problem is quite different.
One option is, I suppose, to continue to use serialization, and then 'fix' the resulting XML to more closely align with the type to which I am converting so that I end up with a working instance on deserialization.
The types I'm converting between don't change often - they just have a lot of fields and I am looking for a more reliable means of copying common information that is better and less error prone than member-by-member copying.
Any advice?

If you can use inheritance (PersonEx : Person), it could be helpful.
If not, reflection should help you to copy values. It's not so painfull at all if you take a closer look.

I should have mentioned - I cannot modify the types, so setting up and inheritance hierarchy is out of the question.
I'm experimenting with reflection now - I'll see how it goes.

Okay, I see. Based on my experiences it wouldn't take many lines of code to copy property values from class to another as long as property names and their types match.
Happy coding

Cool...I got it working  I wrote a generic function that copies matching members from one type to the other. I'm new at this, so I was not able to come up with a good solution to a problem where I need to copy in indexed property. So Person and PersonEx have a member, MoreStuff, which in turn has other string members like Field1, Field2 etc. I also needed to copy the members of Person.MoreStuff to PersonEx.MoreStuff and just ended up calling my generic function with references to MoreStuff and it worked.
This actually worked out well, since I can now at least make sure I copy all members between similar types.
(By the way - the types are messages from BizTalk orchestrations exposed as web services. There is some wierdness with orchestrations exposed as web services, so this conversion often converts between service1.Person and service2.Person even though they are identical - only the typename is different. What a headache )

I think I would either use specialized converter classes, custom explicit/implicit operators, or maybe some exotic kind of software pattern. I might stay away from reflection in this case. Depending on the framework version you're using you could just hammer out an extension method that converts. In any case, the real problem here is the flawed class design (I know sometimes this can't be helped). If you can merge the functionality of the Person and PersonEx classes you won't need any tricksy conversion methods.
Hope that helps...

Reflection is working for me for now. I am using .NET 2.0 at the moment, so this might not be a problem (I think reflection had major issues in 1.0 and 1.1).
I tried writing a custom converter, but there are many similar types that need conversion and they each have lots of properties. I wanted to make sure that I covered all of the properties.
As for flawed class design - I agree that is the case. However, the types in question are actually exposed by BizTalk server through web services. I'd have to modify the underlying proxies to make the class design better. Since I won't be maintaining the solution in the future, I wanted to avoid having to customize auto-generated code. I should have mentioned all of this in the first place but I was too focused on first hand knowledge of the problem 
Thanks! -Erik

Did you know there's an ASP.NET forum? Well there is, so you should post this in that forum, you'll probably get a much better response.
