I'm a beginner to VB.NET. I'd like to make a simple backup program, and therefore I need a way to get a list of all files in a folder, and all subfolders. I've been searching the forum for "recursive file list", but it's too difficult for me to understand. Any simple way to get all files in a folder and all subfolders?
I have a MyList (List Of Longs) in which I need the check a specific relation between any two members of that list, if the relation-check returns true I need to delete checked member.I was used to do something like that with 2 For Next Loops, is there a better way. Would it even work that way with Lists?What is happening when an Item is removed from the List that has not been called by the outer For-Next yet? [code]
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 5 6 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.

Recursive File Copy based on file extension. I have a single root folder that contains numerous folders that contain a few files that I want to extract. For this example, lets state that I want to copy all �txt� extensions and put them into a repository folder.
I have a series of text files in multipule diffrent sub directories. I found the following functions on the Internet:
Private Overloads Function Recursive(ByVal strPath As String) Dim oDir As New System.IO.DirectoryInfo(strPath) Dim oSubDir() As System.IO.DirectoryInfo
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)
2. FunctionLayer -deals with Common Operations which get results from DataLayer and return results to Forms.3. User - deals with User. (For Reusing the User Class in other projects, i have separated this class)Here in Class2 - I have an instance of Class1( ie., DataLayer) for DB Operations.imilarly in Class3- I have an instance of Class1( ie., DataLayer) for DB Operations.Now in my form, If i create Instance of Class2. But When I need user functionality in this form, I have to create an instance of Class3 to this form.

The functions will make a direcotry tree in my debug window, that looks something like this:

What I want it to do is to have it return an array of relitive file paths, from the starting direcotry I give the function. Then I will use a loop to cycle though each file in the array to make certain changes.
I'm an instructor trying to use data from a .txt file to list the grades in a list box. I just want to grab the data from a .txt file, list the total amount of grades in a list box, the mean (avg) and the standard deviation.
I'm trying to recolor all components in a form by using a recursive method. However, it always recolors the form and then stops. How can I make it go past this step? Here is the code I've been experimenting with:
Public Sub fixUIIn(ByRef comp As System.ComponentModel.Component, ByVal style As SByte) Debug.WriteLine(comp) If TypeOf comp Is System.Windows.Forms.ContainerControl Then
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:
I have been working with getting a recursive directory list function going and an attempt that I was considering doesn't seem to work.As it doesnt seem to return all folders.

i have these 2 functions that search for any .jpg files starting from a given path the algorithm works, it's just that it freezes up the gui at times this is why i wish to know how to implement it through a new thread or a backgroundworker maybe.[code]
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...

I've asked a very similar question before, but this time is not about VB syntax, but rather the best approach. I'm making a method that, when passed a component, will recolor it and all components contained within it. Below is the code I have so far, but it is not recoloring all components, instead only a mere few. My main problem is buttons staying in their "3D" styles and not becoming "flat".
[Code]...
The component passed is comp, and the getColor method looks into a database and returns a color corresponding to the part parameter passed to the method. This works for all low-level components and all simple components like labels.As you can see, this is not my preferred outcome. Does anyone know how to recolor spinners, buttons, and menu bars? Again, I need the button to end up being flat.
I have a recursive function in this function i am adding some value to path variable here i want to acess this value outside of function for this what changes i will do in this function.

I am currently creating a little application which will essentially backup my work I do at college. It works by me saving all my work onto a flash drive. When I run the application it will copy all the contents of the flash drive and copying to my college directory and when I'm at home copy to my Dropbox folder. This essentially gives me 4+ areas where my work is saved. Unfortunately, the college computers due to network restrictions and other problems, the use Dropbox on the college machines (I obviously can still access the website).
I wrote some code yesterday which shows a directory listing of an FTP server and if you click on a folder it will show that directory and their is a back button. But I dont think it is efficient and I can tell there will be a lot of errors.

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..
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?
I'm trying to recursively loop through the components in a window, but it never gets past the window to its sub-components. What am I doing wrong?

I'm designing an app that resets permissions on folders so I've made a treeview that uses GetDirectories to populate itself with all folders on a user's computer. The TreeView has the "checkboxes" property set to true so the idea is that users select all of the folders from this treeview that they want to reset permissions on and then click go.
So once they click go I need to loop through all nodes in the treeview and all subnodes etc and test to see if they are checked, then if they are I want to add each node to a list and then in the next routine I would loop through the list and reset the permissions.This is what I am doing at the moment but I keep finding that the objects added to my list are duplicated.For example if I select C:Test and C:TestTest2 in my treeview then I end up with my List looking like this:
I have a VB 2008 Express program that uses a sequence of functions to move a set of image controls randomily until they meet some criteria as returned by a function, named here Passed().The random placements can result in an unsolvable solution, i.e. an infinite loop; So I've implemented a timer check that triggers just longer then the typical solution time (~2 seconds). Assumption being that any attempt longer then typical is likely headed to oblivion.
Upon timer trigger I attempt to reset all the images to a known location and simply recall the preceeding functions to again try placing them until they meet my desired outcome.I believe I am encountering an out of memory type error, due to an apparent corruption of the display (great big white area appears for no apparent reason and program never returns without manual halt). Program does appear to restart properly a couple of times before this 'lock-up' occurs.
Example of my code,
Public CnameA, CnameB as String Public Cmax as Integer = 10 Private Sub Form1_Load(...)
[code]...
Is it possible that the calling of New each time might be filling up the available heap / memory (there are a lot more images then the 5 demonstrated here. I am unsure how to clear it and even if I did would clearing the memory associated with New Point () cause my images to not be displayed?
