hello ,
i developed a .NET software which i want people to download from the net.
i know that if they never used a .NET product they probably dont have the right framework installed on their PC
is there a way in ASP to know if remote computer has right framework or not ?
coz by this i will be able to send him either a small sized file or a big sized one which includes the framework installation
thanks in advance

If they're using IE, then the USER_AGENT of the browser contains the .NET Framework version that they have installed on their system.
Sometimes Firefox/Mozilla will also have the information in its USER_AGENT.
Basically, unless you put something on their computer like an Applet or Silverlight doo-hickey, then you're just going to be shooting in the dark.

tnx,
and what will happen if a prog will run without the framework installed?
will it be friendly or just crash ?
|

Crash. It may display a "Cannot find mscorlib.dll" or it may show "You need the .NET runtime." It's been a long time since I've seen a Windows computer without .NET on it.

Hi Guys,
I've got a problem rounding floats, when adding a small value repeatedly to another, eventually small errors creep in.
float test = 0;
float increment = 0.2f;
for (int i = 0; i < 100; i++)
{
test += increment;
}
if (test != increment * 100)
throw new ApplicationException("Rounding Error!");
What are the available options to get around this?
regards

The Ethically Correct Answer: Floating point arithmetic usually comes with errors because of the representation of the significand. A good understanding of floating-point number representations can assist you in finding a good solution for your problem. Try reading What Every Computer Scientist Should Know About Floating-Point Arithmetic[^].
The Unethical Answer: If you would rather take the myopic path and just get a solution, change your floats to decimals.

Awesome, cheers.
Have no fear, no WTF's from me, i need to understand how stuff works, so i'm going to go with option A.
Cheers for the pointer

Most computer floating-point types can only precisely store integer multiples of powers of two; the size of the integer varies with the floating-point type. For example, even a single-precision float can precisely store the value 1/2, 5/16, or even 16,777,215/633,825,300,114,114,700,748,351,602,688 (that's (2^24-1)/2^99). Unfortunately, just as a decimal representation of numbers that do not factor into a power of ten will be an approximation (1/3, for example, may be written as 0.33, or 0.3333333, but neither is entirely precise) so too with binary representations of factions other than powers of two.
Depending upon what exactly you are doing with your data, it may be useful to re-scale values. For example, if everything will be a multiple of 0.01, you should scale your numbers up by a factor of 100. A single can store precisely any integer up to 2^24, and a double can store any integer up to 2^48.

I've just run NGen on an .exe assembly, to install, and it says all is up to date, but there is no Native Assembly folder in the GAC, nor is there any Native Assembly service. What's up?

Oracle.DataAccess.Client.OracleException . The provider is not compatible with the version of oracle client.
The production server is Window server 2003
I need to sort this out ASAP.

Hello,
I am looking for the methodology to develop the program (preferably webservice) to allow the multiple users on the LAN , to have the certain permission based access on the storage media (like westren digital mybook that connects to the usb port of the computer) ,
so that every user has a purticular quota on the storage media and no body else can access
their folder as well.
need some guidence in this regard.

1) i configured my ms-outlook with rediffmailpro.com and sent a email with invalid email-id i got bounce/failured mail back in response of it.
but my original message comes into .msg file. why?
2) i configured my ms-outlook with gmail.com and sent a email with invalid email-id i got bounce/failured mail back in response of it. but my original message doesn't came into .msg file. why?
why these 2 configureation are differnet? please help.?

It has to do with the way the mail server handles the bounce. Sometimes they include the message inline and sometimes they add it as an attachment. Sometimes the attachment has an .msg extension, sometimes it has a different attachment. Unfortunately, if you don't control the mail server, you can't control the way that they will return to you.

Hi all, What are all the content involved in Content Management system? For ex, .Net contains Xml, linq, sliverlight, ado.net etc.. like that.
Thanks in advance.
|
|
|
|

A content management system manages content, not source code. From a dictionary Web site, one of the meanings of "content," the most applicable here, methinks, is "The material, including text and images, that constitutes a publication or document."
Now, if content consists of text and images, things like XML, LINQ, Silverlight, and ADO.NET don't really fit into this. You can build a content management system with any and all of those technologies, but they are not the content.
If you'd like to learn about content management systems in the .NET world, you can refer to MojoPortal[^] or DotNetNuke[^]. Those are relatively mature content management systems in the open source space. Ostensibly, that means that you can dig through the source and figure out how a content management system works, why it works the way it does, and (most importantly) WHAT comprises a content management system.

I m totally confused in PrincipalPermission Class, i tried to read details on mcdn but no use, can plz any1 tell me abt this class.
MSDN says " Allows checks against the active principal (see IPrincipal) using the language constructs defined for both declarative and imperative security actions. This class cannot be inherited. "
i m not getting
checks
active principal
language constructs
thanks in advance.

Basically, Active Principal is the security context for the current user.
It says that security verifications can be made in 2 ways:
declarative - in this case the security checks are implemented using attributes.
Take a look here for Declarative Security[^]
imperative - in this case the security checks are made in code.
See this[^] for Imperative Security.
