Re: Pocket PC Application. - C# Discussion Boards

Hi all,

Iam developing an pocket pc application in .NET Compact framework and run it the emulator. I dont know where the EXE and other application files are stored in that emulator.

Sridhar.

The application is loaded into memory, along with dependent assemblies from dependent projects. To actually install the application and related content files you need to create a deployment project, then deploy into the emulator.

For more information about developing Smart Device Application and deployment projects for said projects, read Developing Smart Device Applications[^] in the MSDN Library.

If by "trace" you mean capture, then yes you can capture the [Tab] key being pressed. Handle the KeyDown event (or, in a derived control, override OnKeyDown, being sure to call at some point base.OnKeyDown) and check the KeyEventArgs.KeyCode for Keys.Tab.

You can extend controls to create your own, or create a UserControl derivative to contain multiple controls (what's called a container control). There's really not much you can't do.

If you're new to programming, I suggest browsing the relevent articles here on this site and checking out books about .NET at http://www.microsoft.com/mspress[^].

hello
i am calcualting factorial and saving its value in double data type. But double can't calculate factorial of >170 .
Plz help me if u know how can i calculate factorial of above 200 or say 500 factorial.

Regards

The following appears to work for me:

private double factorial(double f)
{
    double num = Math.Floor(f);
    if(num < 0)
    {
        return -1;
    }
    if(num == 0)
    {
        return 1;
    }
    else
    {
        return (num * factorial(num - 1));
    }
}

hi you must use arraylist;
do this:
you must define the multiplication yourself on the arraylist.
each elements of arraylist contains only one integer.
say
for( int i=1;i< 500;i++)
{
multiplay i in each elemnt of arrayList and add its more than 10 of element to next element such you do on paper.
}
you can calculate n! by this

try using decimal instead, if still too small, look for a BigNumber class, although that will slow things down. Why on earth do you wanna calculate such huge numbers?

That's usual demonstration of difference between recursive vs. iterative algorithm in terms of speed.
(Iterative one is much faster in this case)
Hmm and practical use of 500! ? Unsure | :~

benchmarks maybe...

You might want to check-out the C# BigInteger Class[^] article here on CodeProject. That may help.

I was chagrinned that .NET doesn't have a BigInteger class, but this one by Chew Keong Tan looks good. I gave it a quick try with this:

public static BigInteger factorial( int n )
{
   BigInteger result = new BigInteger(1);
   for( int i = 1; i <= n; i++ )
      result = result * i;
   return result;
}
... And later, in Main(): 
Console.WriteLine("factorial of 170  = " + factorial(170) );

And it works just fine, giving:

7, 257, 415, 615, 307, 998, 967, 396, 728, 211, 129, 263, 114, 716, 991, 681, 296, 451, 376, 543, 577, 798, 900, 561, 843, 401, 706, 157, 852, 350, 749, 242, 617, 459, 511, 490, 991, 237, 838, 520, 776, 666, 022, 565, 442, 753, 025, 328, 900, 773, 207, 510, 902, 400, 430, 280, 058, 295, 603, 966, 612, 599, 658, 257, 104, 398, 558, 294, 257, 568, 966, 313, 439, 612, 262, 571, 094, 946, 806, 711, 205, 568, 880, 457, 193, 340, 212, 661, 452, 800, 000, 000, 000, 000, 000, 000, 000, 000, 000, 000, 000, 000, 000

At least it got the same number I calculated off the top of my head. Laugh | :laugh:

(I formatted with commas and spaces to prevent extreme horizontal scrolling Eek! | :eek:

in this post! (and no, I didn't insert them manually -- do you think I'm nuts?))

Hi sylvain2222

Code Url[http://www.codeproject.com/dotnet/PrintingFormReport.asp[^]]

I have some problem in using you code in C#. Please help

1: How to call datagrid control, List View, Tree View like these controls?
2: How to print date?
3: If I want to print some controls in a form like I want to print textbox, checkbox, datagrid but skip the labels or other controls?
4: Can we skip specifically some label or single label or any other control?
5: Can I skip Form Title for Printpreview?
6: I have some special user controls like gradient labels. Can I also take this kind of controls in printpreview?

I shell be very grateful if you tell me soon and in C#. Please

I am waiting for you quick response…
