Any Algorithm To Shorten Very Large Integer?

Dec 8, 2010

I have a function which generates a very large Integer (I do this by using Biginteger from vjslib.dll and I am able to operate all kind of arithmetic operators on such a biginteger.) But, My goal is to shorten this big integer into a small integer. Is there any algorithm? or a mathematical Formula which I can use to represent it in a small integer and use some reverse formula to get the original Big integer?

The big integer my function creates goes like this:
98761210112313489375987956157462364864823458794572 34573485683465868234568613123749081377932457923457 93475897836587236458678234568234658362458762347895 68932456892346578636123846715376123475745723645666 38247687346128346812364812364816341384612384678345 76341236412783461278346781236481263489126348971238 41134681273467812364789

I do not want to represent my bigInteger in a higher base as it will not be possible to do conversion into higher bases with such a large integer.

Speed Up Algorithm - Sieve Of Eratosthenes - Program Hangs On Really Large Values Of N (try 10 Million)

Aug 17, 2009

I've written an algorithm that I believe to be correct for computing prime numbers up to n with the Sieve of Eratosthenes. Unfortunately, this program hangs on really large values of n (try 10 million). Here is what I've written...

Protected Function Eratosthenes(ByVal n As Integer) As String
Dim maxValue As Integer = Math.Sqrt(n)
Dim values As Generic.List(Of Integer) = New Generic.List(Of Integer)

[code]...

How might I speed this algorithm up? Where are my bottlenecks?

Large Multidimensial Array - Write A Program To Do Markov Chain But States Are Quite Large

Jun 9, 2011

I want to write a program to do Markov chain, but my states are quite large. First of all I calculate all the transition probabilities and revenues for all states(1381860 total states), and store in a multidimensional array. Public RevArr(0 To 9, 0 To 750, 0 To 282) As Long

After that the iteration of markov chain should use these as inputs to calculate the steady-state probabilities. But when I try to run the main code I got this error.Exception of type 'System.OutOfMemoryException' was thrown.

The following is the declaration of second array I add just another dimension for storing all the iterations, but I get this error. Dim stateprob(IT + 1, 0 To 9, 0 To 750, 0 To 282) As single

Shorten Selected Value In ComboBox DropDown List For Display

Feb 21, 2010

I have a combo box that has a drop down list with long values in the drop down
Ex:

LB - Pounds
GR - Grams

When the user selects on of the values I want to just show the Abreviaqtions and not the descriptions. So when the drop down is shown it shows

LB - Pounds
GR - Grams

When the user selects "GR - Grams" from the drop down list "GR" is the only this shown in the combobox. I've tried TextChange,SelectedIndexChange and SelectedValueChange but I can't get them to work.

Error After Implicit Conversion Of 1 Dimensional Array Of Integer To IEnumerable Of Integer() ) ?

Apr 25, 2011

I'm trying to create a linked list of an array of integers. Why is the following implicit conversion required?

When I run the code that contains that conversion, I get the following error.

As a real-time data acquisition user control data (a packet of an array of bytes) arrives every second, is converted into an integer array and inserted into a linked list.

The most recently arrived data is painted as coordinates on a grid at the right of a PictureBox using Graphics.DrawLine (pen,X1,Y1,X2,Y2).

The oldest data (arriving 120 seconds ago) will be drawn at the leftmost portion of the Picturebox.

Why a linked list rather than a list? To display 120 views of time sequence data, the draw routine the most recently inserted node to a node that points to Nothing. How do I limit the length of the linked list to 120 nodes and always ensure that the last node points to Nothing?

Do While Not item Is Nothing
item = item.NextItem

'AddressOf' Expression Cannot Be Converted To 'integer' Because Integer Is Not A Delegate Type

May 13, 2009

I'm trying to convert a VB6 project to .NET, but I get problems with some callback functions, and the following message comes up: "AddressOf' expression cannot be converted to 'integer' because integer is not a delegate type" I've seen several solutions to similar problems like this, but I am not able to understand this issue with delegates.

After the conversion, the code look like this:

Declare Function vsmsgwSetDataPackageCB Lib "vsmsgwW.dll" (ByVal PACKAGE As Integer, ByRef arg As Integer) As Integer
Dim arginitP As Integer

[Code]...

Which gives the error: Method 'Public Function PackageCB(HisNodeID As Integer, ByRef data() As Byte, ByVal length As Integer, ByRef arg As Integer) As Integer' does not have the same signature as delegate 'Delegate Function DelegatePackageCallback(hwnd As Integer, lparam As Integer) As Integer

Also FProducts.Serial_number, 0).ToDictionary doesn't work.

Value Of Type 'System.Linq.IQueryable(Of Integer)' Cannot Be Converted To Integer?

Aug 11, 2011

I am new to EF Linq and I have been struggling with this query for a few days. From reading this forum, I have managed to get this far:

Dim noPic = (From f In myEntities.FriendLists
Where (f.UserID = Profile.ID)
Select f.FriendID).Except(From g In myEntities.GuestLists
Where g.EventID = _id
Select g.FriendID)

[Code]...

I am trying to get everybody from the FriendList who is not already on the GuestList to display in a Repeater control. After reading the forum I was able to append .First() to noPic at the myNoPic declaration and finally get a result but that only gave me the first element. Does anybody have any advice on how to accomplish this?
