.net - Recursive Function Not Returning?

Nov 28, 2011

I am hopeing someone can help me here with a recursive function I have that is not returning either true or false as I would have espected it to. The function loops through a Active Directory group for its members and then calls itself if it encounters any groups within the membership in order to gets its members as well. I am trying to return either true or false based on if any errors were encountered but not haveing any luck at all. It appears to just hang and never return back to the primary calling sub that starts the recursive function. Below is my code I am using:

Returning A Function Vs. Returning Variable Name?

Dec 12, 2011

My brain may just be fried since it's the end of the semester, but my teacher kicked this back to fix and resubmit...she said that I am "returning the name of your function rather than your variable name".

Here is my code for all 3 forms.

These are forms to calculate the cost of getting a cell phone package.

Recursive Function Vs Factorial Function

Nov 20, 2009

Can someone explain to me what the difference is between a recursive function and a factorial function. I know that a factorial function returns the product of all the numbers from 1 to itself. But how does that differ from what a recursive function does

Recursive Function Works On X86 But Not X64?

Mar 12, 2011

I'm making a program that can mark my shooting cards and i have created it and it works nicely But i want to get as much speed out of it as possible so I switched my target CPU to X64 and sure enough my recursive function threw a Stack overflow exception telling me i need to make sure i don't have Infinity recursions. Strangely when I set It back to X86 the same recursive function works...

Recursive Function Using 3 Variables With 3 Different Values

Feb 14, 2011

I have 3 variables. Lets call it "a", "b" and "c". These 3 variables can "independently" have 3 different values. Lets say: "1", "6" and "10". when you think of them as combination; there are (3^3) 27 combinations. I am told that it can be done through the recursive functions. However i am not a good developer to handle with that. Would u please help me?

- 3 variables and 3 different values are simplified. In fact; the numbers of variables and different values can vary.

- i know only the language, visual basic in .net; please don't answer in other coding languages.

additional note: i am going to put the these combinations in the string format into a collection.. for example "1;1;1", "1;6;1", "1;6;10".. and so on..

Recursive Function With Dynamic Treenode

Aug 16, 2011

I have a recursive function wich objective is scan an structure and represent that structure with treenodes. Inside my function depends the structure I'll have to create another treenode inside my treenode or just create a node. My problem is that I don't know how to remember my treenode position when I have to call my function again.

If strTop.TextString.ToUpper = "DMN" Then
gcTreeno.Nodes.Add("Node")
Else
Dim perf As New TreeNode
gcTreeno.Nodes.Add(perf)
End If

if i would like to write next time a node into perf, how i could do it?

Improving Recursive Active Directory Function?

Mar 2, 2012

I'm hoping to improve the performance of the below as well as return the GUID of each user.

I've converted and modified the code found here for searching through groups recursively to get all the members and their details and adding them to a class collection. However I also need to capture the user's managers details so I'm calling the AD twice for each user. This doesn't seem efficient as many of the users will have the same manager. It would seem logical to get the distinct manager details from the collection class and call only these, then replace them wherever they occur in the collection.

I'd also like to be able to get the user's GUID, I've tried accessing it directly as a property of the collection, but it doesn't return anything.

I'm using vs2005 and .Net 2.0

Public Class ADCLass
''' <summary>
''' Calls recursive function to return users in group

Rewrite This Recursive Function To Remove The Recursion?

Dec 29, 2009

I got that little function(I changed the name of variables)

Private Function everythingLinked(ByRef myClass As cls, ByVal found As Boolean) As Boolean
If Not found AndAlso myClass.checked = False Then
myClass.checked = True

[code]....

I want to rewrite it so it would only be loop and no recursion and I'm currently lost?I'm passing a class to this function(with a starting value for found as false) to know if it is linked to the middle of the tree. The class got an array with a maximum of 4 link to other class and it can be circular(this is why I have a checked_link boolean).It does the recursion until there is no more link(return false) to check or until it find the middle link(return true).

edit?for an example, this

in pos 0 got link with 1
in pos 0 got link with 6
in pos 1 got link with 0

[code]....

middlepoint would be pos 15 the code above can prove that every position can be linked with the middlepoint so initial arg would be

everythingLinked(random pos, false)

and in this case it would be always true

Working Function Adding Recursive Breaks It?

Oct 21, 2010

I am looping through all folders on the computer in a background worker. Starting with just the C: drive, the function works perfectly I've been tasked with adding recursiveness to this function to loop through all subfolders within each and every folder.

This is the working code without recursive. Startpath is set = "c:".

Private Sub BackgroundWorker1_DoWork(ByVal sender As Object, ByVal e As System.ComponentModel.DoWorkEventArgs) Handles BackgroundWorker1.DoWork
Dim fs As New FileSystemObject
Dim fsfolder As Folder
Dim subfolder As Folder

[Code]...

EDIT: I was doing some testing and threw in an if check to skip the C:$ folders. Working ok so far and noticed something really strange. It doesn't loop through all the folders in the C: drive. I think it will loop through only the first 2 folders. One is C:Boot so I skip that and the other is C:Dev-cpp. It won't loop through the Program Files, Program Files (x86), or Users.

File I/O And Registry :: Using Recursive Function For Directory Tree?

Dec 2, 2008

I am trying to write code to save (in a text file) a list of folders/files that are contained in a specified folder. I want the list to be formatted to illustrate the folder tree structure by indenting sub-folders and there related files according to their relationship to the base folder.

I found and incorporated a recursive function for listing file & folders. This works fine for generating the list, but I am having difficulty with code to determine the sub-directory level relative to the base folder. the code that I have included below sort of works.......The problem seeme to be when going from a folder that is multiple levels up? from the base to one that is only one level from the base. Refer to my sample output. This should not be as difficult as I seemed to have made it, but recursion kinda blows my mind.

Code:
' The following function call is in a button handler
GetFilesFolders(txtBaseFolder.Text)
Public Sub GetFilesFolders(ByVal path As String)

How To Exit Recursive Function And Record Required Data To List

Jun 18, 2010

I want to exit a recursive function once the a number is repeated in a list. i.e. In the following code I have 'AST' as a list. How can I stop adding data to the list once the first number repeated?

The result in the below code is:
1 2
4 5 1 2
4 5
1 2 4
5 1
2 4 5
1 2
4 5 1
1 3

3 3
1 3 3
5 6
3 3 1
3 3
5 6 1
5 6
1 5 6
1
What I want for AST to be: 1 2 4 5 1, because 1 is repeated.

Just Add to your form a richtextbox and a button.

Asp.net - Returning Object From A Function?

Feb 8, 2012

If an object is created inside a function and the function returns that type of oject how is the memory handled.

Example:

Public Function GetEmployee(employeeid as integer) as employee
Dim oEmployee as new employee
oEmployee.FirstName="Bob"

[code]....

Does the variable that receive the object still a pointer to the memory location that was used inside the function?What about when you do a oEmployee2=oEmployee.Is oEmployee2 just a pointer? And any changes to oEmployee will now affect the other. Just trying to understand it from a memory perspective and how that scope works?
