Recursive File Search - Series Of Text Files In Multipule Diffrent Sub Directories
Jul 21, 2010
I have a series of text files in multipule diffrent sub directories. I found the following functions on the Internet:
CODE:
The functions will make a direcotry tree in my debug window, that looks something like this:
CODE:
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.
Something like this:
CODE:
Any ideas on how to acomplish this?

i have been trying to search a specified directory and all sub directories for all files that have the specified file extension. However the inbuilt command is useless as it errors up and dies if you dont have access to a directory.
Private Function dirSearch(ByVal path As String, Optional ByVal searchpattern As String = ".exe") As String()
Dim di As New DirectoryInfo(path)
Dim fi As FileInfo
[code]......
However i get an "System.NullReferenceException: Object reference not set to an instance of an object." when i try to access the data stored inside the filelist string array.

one of the BIG hurdles in my simple project, making a search engine. I don't know how at all. The search engine need only to search in one Directory with its sub directories and txt files for criteria, and display the results, with option open from the results. any basic code or example maybe?

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).

Before I start, I'm not 100% sure this is the right place to ask. Okey, so I'm making my own Notepad, which will contain newer features. (Private use only though) One of them being tab control.
Now I want the program to be in the "Open With..." menus for all files, so I can choose myself.
And if the program is already running when user opens a new file, I want the text to appear in a new tab, instead of a new window of the program.
I tryed to be straight forward, and keep it short. So if you need more info, fell free to ask.

I have an issue with avoiding this exception and trying to continue on with my code.im trying to search directories for a file. this is my code
vb.net
Dim As FileInfo() = d.GetFiles()'Errors here
Dim fFile As FileInfo
For Each fFile In Files
If Not fFile.Attributes = FileAttributes.System Then
If fFile.Extension = Extension Then
[Code]...
It's the files located in the C:System Volume Information Directory.How can i avoid the exception but continue on. I can't put a if then statement around the variable declaration. because then i can't use the variable. And catching the exception just causes my routine to stop.

I am trying to write a program that writes information from texts boxes to a text file on the users hard drive. I would like to create a new text file if one already exists, for example if text1.text exists, it creates a new text file called text2.text, then if text2.text exists it creates text3.text and so on. Here is what I have so far:
[Code]...
I've tried fooling around with if statements to create a new file but it doesn't seem to be working. Additionally, How can I write to a new line in a text file. For example there are 4 text boxes and each string from each text box gets its own line.

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 wrote this code. It works, but when the directory has a lot of subfolders it freezes up. I really only need to access the folders created in the last 24 hours. I cannot however figure out how to compare the subfolder to time.

I wrote a Windows Forms script that searched for all non-hidden and non-readonly folders in my system. But the script itself, when run initially, runs for like 5 minutes. Subsequent opens take much less time. I was wondering if there is a logical error to it, so as to why its running so very slow.

Simply put, I have a text file full of reg values. I want to search the text file for X number of reg values. I want to then, have those values and their dword values (whole line + next 3 to 4 lines in the file) listed in either another text file or an Excel spreadsheet. Regardless of the format, I would like to have the values sectioned off for each of the values searched (probably tables of some sort).[code]...

i'm currently making a client database program for work that stores data in multiple text files (so that the information won't be confused as to which info belongs to who in the database). Each client has his/her own text file, which isn't really a problem although i realize it's a bit messy. A listbox holds items, each item a person's name.When the listbox selected index is changed, the streamreader opens the corresponding textfile, which is as such: "John Doe.txt", and populates the correct textboxes with the information stored in "John Doe.txt".What I'm unfamiliar with is implementing a search function.
1. search query entered
2. streamreader reads through all txt files in a directory looking for matching keywords.
3. if a match is found in a txt file, it looks at the name ("John Doe.txt"), gets the corresponding listboxitem, and finally, once the textboxes have been populated with the info in the file, highlights the matching keywords.
4. then i figured if there was more than 1 match over more than 1 txt file, you could repeat the process and skip to the next match via the tab key (like the find feature of a WebBrowser or other such application).
What i don't understand is how to read multiple text files, search in keywords, highlight the matching keywords, or the tab function..I know that's a lot to ask on a forum, but I had nowhere else to turn.
