How to set JIT type?

Dragonfly_Lee31-Jan-09 19:07

Hi, all

A little bird told me there are three type of JIT: Pro-JIT, Ecno-JIT, Normal-JIT. How can we set the JIT type for our application?

Thanks.

If you google this and find that it's not a pile of BS, I'd sure love to know about it.

I just want to know if the JIT type can be decided by Microsoft or programmer. I am pleased if you can offer an effective link, too. Smile | :)

High on that oak-tree, the birds are singing about native compilation and stuff. It's even the right answer to one of those "tech interviews" that you can find with Google Smile | :)

The moderator on the Microsoft forum has some other explanation;

Shawn wrote:
NGWS - now that's a blast from the past. It stood for Next Generation Web Services (one of the many code names .NET went through before it was released).

You're correct that Pre-JIT is what today is called NGEN. You can use it by running ngen install <path to="" assembly="">

(Source)[^]

What those birds didn't read;

MSDN says
Once you create a native image for an assembly, the runtime automatically uses that native image each time it runs the assembly. You do not have to perform any additional procedures to cause the runtime to use a native image. Running Ngen.exe on an assembly allows the assembly to load and execute faster, because it restores code and data structures from the native image cache rather than generating them dynamically.

I are troll Smile | :)

Thanks, Eddy Vluggen.

Actually, I know the differences for these three type of JIT. I just want to know how to choose the JIT type and the related cmd.

I don't think we get to choose that much, only whether we want to precompile or not. I couldn't find a satisfactory answer either D'Oh! | :doh:

Hi, don't know really where to post this but because I wrote the program in c# to solve this problem, I guess its as good a place as any.

Project Euler is for bored programmers (like myself) that like to solve problems.

Well I am pretty sure I solved problem 9[^] correctly, yet the site tells me i'm crazy.

The answer I got was:
{200, 375, 425} [a^2 + b^2 = c^2]

And the product of abc is 6375000000.

Am I reading the problem wrong?
This checks out on my end, please double check this for me and let me know I'm not crazy.

Heres the code if you want to see how I did it:

int objectNum = 1000;

for (int counterOne = 1; counterOne < objectNum; counterOne++)
{
    for (int counterTwo = 1; counterTwo < objectNum; counterTwo++)
    {
        double a = Math.Pow(counterOne, 2);
        double b = Math.Pow(counterTwo, 2);
        double c = Math.Sqrt(a + b);

        if (Math.Truncate(c) == c)
            if (counterOne + counterTwo + c == (double)objectNum)
                Console.WriteLine("{0}, {1}, {2}", counterOne, counterTwo, c);
    }
}

Hi All,

I am currently working on using the ajax autocomplete application that queries from the database for the input entered into the textbox. However nothing shows when i load it up and i am unsure as to whether it is to do with the way i have created the web method or maybe to to do with the static method. Nonetheless it does not work.
Would anyone be able to provide assistance for this? Many Thanks + Kind Regards.

assume i have a class named "Student" with the attributes of "Name", "Id" & "Address".
i make a list of "Student" type where i add only "Name" & "Id"
i want to show this data in a data grid view.
if the data grid is custom then how could i manage the column number here?
i want to get the number of attributes which i add in the list & it's may be dynamically changed.

thanks in advance.

Maybe you mean property in you case, not attributes.

You mean you did not want to display the Address in datagrid view?

Yes.
i don't want to add Address in datagrid.
& i just want to give the list in datagrid as source & datagrid will manage the columns from the the list.
so how can i define that how many properties did i add in my list?

If you want to print a specific control, you can render it to a bitmap first, then print that.

In my DataGridView I have three columns whose ValueType is set to double so that it'll accept only numbers. Now I want it to always show 2 decimal places like "17.00" instead of "17". How do I do that?
