Click the Site Map link under NEWS & COMMUNITY. There is a Development Lifecycle category that has an Installation sub category that lists 93 articles. I have no idea what's in there but it sounds like thats what you want to look at, yes?

Hello everyone,
I am actually preparing for a job interview and I had my first telephone interview last week. One of the things that came up in the discussion was generation of .NET bytecode directly!
Well, I am not supposed to know how to go about it, I guess but it would be nice to talk about it intelligently in the interview. Does anyone know where I can get some information about it and if someone has tried doing something like that. It would definitely be nice to be able to suggest some ways one can go about it etc.
Many thanks,
Keith

CodeDom.Compiler just is a wrapper around the C# compiler/VB compiler.
CodeDom is nearly useless for generating code because it supports only a few operators, I've often run into cases where CodeDom cannot generate the code I wanted.
And a call to an external compiler is quite expensive if you just want to dynamically generate a method!
Usually, generating .NET bytecode directly means Reflection.Emit[^].

Hi Guys,
While i understand the differenced between the operator and the Equals method, is there a rule of thumb for when to use them in code?
I've always tended to use == for value comparisons of known types (strings, ints, etc), and Object.Equals() when comparing unknown objects.
I have a colleague who insists on using Object.Equals() for every comparison, and while i don't like it, i can't think of a reasonable reason not to use it.
What are other peoples thoughts on this?
Cheers

If you did understand it, you wouldnt be asking
== and ReferenceEquals is more closely related, and == does ReferenceEquals if not overriden.
You can see the effect with structs/valuetypes, create 2 structs of the same type, and go through all 6 permutations of equality tests.

Ok, if == is more closely equated to ReferenceEquals, then >=, <= , >, < are all value operators, and == is a reference comparison operator and doesn't relate to the other equality operators at all?
I mean, i see the following quite regularly:
If (myDate.Equals(defaultDate) || myDate < minDate || myDate > maxDate)
throw new ArgumentOutOfRangeException("myDate");
that does cause me to do a double take, as i would expect it to be
If (myDate == defaultDate || myDate < minDate || myDate > maxDate)
throw new ArgumentOutOfRangeException("myDate");
Hence why i ask. What's the rule of thumb? In this instance both work the same way.
Cheers

Object.Equals is a virtual method (and the static Object.Equals(a,b) just does a few null checks and calls a.Equals(b)).
Operators are static.
Virtual methods are called using dynamic dispatch - so Object.Equals always does a value comparison if supported by the runtime types.
However, the == operator is called using static dispatch - if you compare two string variables, it does a value comparison, but if you compare two object variables, it does a reference comparison - even if the object variables contain string objects!

Object.Equals() should be used whenever you want to check Identity not equity.
Reference type equals returns true if both objects are pointing to same memory location. It is not going to return you true if both object have identical values(except string type). So Object.Equals() checks for Identity not equality.
But if you are using Equals method on value types it check for Equility not identity
So When you want to check Identity use Equals method
But when you want to check for equility use ==
Be aware while using Equals method with values types as it may have performance issue while boxing the values types sp better to go with ==
Addition to this Object.Equals method provides Comparison type paramter where you can ignore case sensitivity
Please have some thoughts on this question so that i can also get some feedback
Thanks and Regards

Just wondering whether .NET is required for .NET framework? I checked it requires XP SP2. Now I am not sure whether current updates of SP2 automatically installs .NET or not because we have to decide whether we go for .NET based solution or not and only stat which I could grab that majority of users are using IE7 for browsing.

I don't see why one needs the other, its not like they share the same name/purpose/structure/meaning of existence.

how can use filesystemwatcher to check when a file is drop or open in ftp folder
|
|
|
|
|
You can't - not directly with ftp. There are lots of tricks you could do, but a filesystemwatcher isn't going to help because it doesn't work with FTP.

I searched all over for the answer to this problem - and finally found it
Thought i would post it in case anyone else is suffering with it
The class derived from Service base must have the property
CanHandleSessionChangeEvent = false
Otherwise Service Manager/Start Service will hang
then give the
message "Service would not start in a timely fashion"

Hi all,
I have a vc++.net application that draws a graph at runtime after a certain time interval.My prob is that while the graph is being drawn on the GUI,if I open another window or any message box comes over the GUI,that particular area of the graph gets erased and is not redrawn.
Please help me.I am a beginner in vc++.net.
Any help or suggestion is welcome.
Thanks,

How?

Are you also a beginner in communications? Think about what you are doing here using this forum. You are asking people to freely use their time to help you. At the very least you should make an effort to communicate your problem clearly, completely and succinctly.
Member 4744683 wrote: draws a graph at runtime after a certain time interval
So based on that one could guess that you do the drawing in a timer event handler. Drawing needs to be done in response to Draw events or WM_PAINT messages, not timer events. Also a Picture control can be used. The Picture control would then do the drawing in response to the Draw events. To use a Picture control you would create an Image and draw into the image then assign the image to the Picture control.
good luck
