Hello
can help me in my problem.I need deal with very big number to add,sub,multi and divide I can do the add,sub and multi but can't do the divide can help me.
I need divide very long integer number such that
x=444444444444444444444444444444444444444444444444444444444444444444444444

or more that each number consist from more of 300 digit can I divide it and result is div and mod.

thanks.

I can't see any possible application for that sort of number crunching. What is a 300 digit integer anyway?

Look at the maximum sizes of the datatypes, you're going to find you can't actually store numbers that big.

Apologies for a severely lacking knowledge of the datatypes. At least I can go home today knowing I learnt something.

IIRC Microsoft J#[^] has a BigInt implementation that can be used by any .NET language. It looks like they're dropping j# so get it while you can!

J# has lost all support long ago. I did use its BigInt on occasion.
There finally is a bit integer type in .NET, I haven't tested it yet, I'll wait for an official 4.0 release...

I only read code that is properly formatted, adding PRE tags is the easiest way to obtain that.

I used to divide bit-by-bit with the standard binary long division, which gives the quotient and the remainder at the same time. But there are faster ways, such as SRT division (quite complicated though)

Problem with events...

I have a problem...

public delegate MyDelegate()

class MDIParent
{

public event MyDelegate myEvent;
public MDIParent() //Constructor
{
// Create and open MDIChild from MDIParent Constructor
MDIChild mdiForm = new (MDIChild())
}

Class MDIChild
{

public MDIChild //Constructor
{
((MDIParent)this.MdiParent).myEvent += new MyDelegate(myPriveteMethod);
}

}

Well, as you can see, I

- Auntomatcally create a MDIChild from MDIParent constructor
- In the MDIChild constructor I try to suscribe to an MDIParent event

It gives me a SystemNullException. It perfectly suscribes if I do it OUTSIDE the MDIChildForm constructor. I suppose it is becouse parent form is not still initialized (child is created form INSIDE parent's constructor).

I need to open MDIChild from the begginig, and suscribe to event at the begginning, too. Any workaround to do this without using the constructor

Thanks!

How about passing MDIParent instance into MDIChild's constructor?

class MDIParent
{

   public event MyDelegate myEvent;
   public MDIParent() //Constructor
   {
        // Create and open MDIChild from MDIParent Constructor
        MDIChild mdiForm = new MDIChild(this);
   }

Class MDIChild
{
   public MDIChild(MDIParent parent) //Constructor
   {
      parent.myEvent += new MyDelegate(myPriveteMethod);
   }

}

Best wishes,

The issue is that the MdiParent is not set within the construction of your child window. It's a property you set after the MDIChild has been created. You could create a register method on your child class and after you've set the MDIParent of the class, call MDIChild.Register( ).

Not the best way, I'm certain, however it would do what you needed.

Thanks!

I knew that was the problem. Parent was not completely set becouse I tried to suscribe inside child constructor, wich was invoked from the parent constructor.

I tried your suggestion. It worked! But, how, and when to suscribe?

Today morning, after a good rest, everything came clear. I just moved the suscription to the Forn_Load event Smile | :)

Thanks!

Probably post in the SQL forum. What do you mean dot(.)? If you've got them side by side then you'll have different instances. The instance will be part of the connection string.

Problem with a newer version of a dll

KittyKit27-Jan-10 2:58

Hello

We have a asp.net website that has reference to simIO.dll which was developed by my predecessor. I have the source project of simIO.dll in hand. This inturn refers to a 3rd party dll called config.dll (using DllImport). Now the 3rd party has released a newer version of config.dll that I need to update in our website.
I first tried to replace the new version of config.dll in the system32 folder and got the following error.

The specified module could not be found. (Exception from HRESULT: 0x8007007E) can not be loaded.
But it works fine with the older version config.dll
Can somebody advise me how to change the reference to the new dll?
Many thanks
Kit
