Searching For File Names?
Aug 18, 2009
I have some code that does what I need it to do, But I am going to have make changes to accommodate the user request. Basically the program searches a folder for a paint code, ex. 351X035. When the code is found it displays a link so the user can click it to open up a PDF. The way I have it setup now is that they have to know the exact paint code for it to pull the link to the file. I need to search to find the file(s) with less than the exact code.

I have a directory 'C:Test' with three files in it:
A23456789.txt
A1.txt
G 5.txt
And I run this command:
Dim FileArr = Directory.GetFiles("C:Test", "*1.txt", SearchOption.AllDirectories)
All three files are returned.I understand that this is by design and .NET searches the 8.3 short file names as well.But is there any way to override this and search the actual file names only?Surely, in this day and age there must be a function to do this. Or do I have to write my own?I would like the search function to have the same behavior as the Windows Explorer for consistency.

I am experiencing a problem when trying to convert a rather large VB6 application into a .Net 2005 application. Everytime I try to convert the project I get the following error: "Upgrade Failed: Exception occurred: Can't use character device names in file names"The weird thing is i have tried to convert the project using .Net 2003 and I do not get the error, it does convert.

I am working on a VB Console Application that takes an Autocad drawing type DWG and converts it to a PDF using a shell command that calls a third party application. In this case, acmecadconverter.exe from www.dwgtool.com. Then the PDF that is created needs a unique watermark, so I call a second application for that called pdftk.exe from www.accesspdf.com/pdftk/.
Everything works as intended, except when I try file names that contain spaces. The file system object does not tolerate spaces in the drawing file name. For instance, the following command gives me a system.io.filenotfoundexception...
My.Computer.FileSystem.RenameFile("Test Flowchart1.dwg", "Test~Flowchart1.dwg")
It's the same problem for all of my File System commands. Either file not found or invalid arguments.
The complete script I'm using is here:
Code:
Sub Main()
Dim arrArgs() As String = Command.Split(","), _
i As Integer, folderPath As String, myPart As String, _

I need to open an excel file from vb.net and then search it for specific data. I then need to take those data and insert them into text boxes on a form that i have created. This is all controlled by a button click. I already have some code that will open a file dialog box and let me navigate to the correct file, but I am having trouble with the search portion. I have tried the Find function but I am not sure of the proper syntax. I am using Visual Studio 2008 and Excel 2003.

I'm trying to do some simple XML manipulation by searching one XML file for a set of nodes and inserting them into another XML file at a specific location.I'm able to succesfully create a node list from one of the files using the following xpath statement [code].....
I'm struggling to see how I can easily select any node I want within the first XML file but the second file refuses to play ball! I've attached the second XML file should anyone wish to check that I've interpreted the structure correctly.

I am attempting to gather a group of file names from a directory. I am able to do this. I tested the code by having the list populate into a listbox and all desired items were added to the list.
Here is my code:
Dim di As New IO.DirectoryInfo(strPath)
Dim dir1 As IO.FileInfo() = di.GetFiles("*.txt")
Dim dFiles As IO.FileInfo
ListBox.Items.Add(dFiles)
However, a listbox is not my desired output. I am attempting to write these file names to a text file for purposes of then parsing the information to a datatable to compare with another datatable. How to get my filenames written to a textfile.

I'm trying to make a script that searches for multiple .TXT files in a directory, and then searches the text of each file for a matching string(ie. "turtles"). It will search each file for the word "turtles". I've been on google trying to figure this out for a while, I'm guessing StreamReader is the way to go?

This is an veriation on a previos thread of mine (les complicated I think)
All .png Image Files in a Folder is named as 6 diget numbers.
Forinstance a "2" wil apear as "000002"
"22" as "000022"
"42" as 000042"
Can this files be searched by numeric value insted of a string?
So if I then searced fot the value of 2 I will get file named 000002 and not file named 000042 or 000022

I have been searching all over the forum and internet, but seems to have a hard time finding some help on how to search for a file at unknown location.
The reason is that, I made an easy form that helps some friends of mine find around a website more quickly.
Now this is what I want.
They have a game installed on the computer, and I want my program to search for this file and execute it afterwords.

I need some guidance on the best way to proceed with searching a file content.I have a large file (see attachment) that is in text form, some of these files could be upto 50 times as big, therefore creating a huge file.These files contain information that is produced from another application and therefore I am unable to change the format of the file.This file contains information that I want the user to be able to be able to enter search criteria in a form that then searches this file and returns information. The individual information is split into sections of data and this is defined by the section start label lbl{ and the end label }} Therefore the below information highlighted in bold is an individual section
lbl{-32768 21 12 0 text {Equip no: P-102BDescr 1: RECYCLE PUMP-BDescr 2:}}lbl{-32768 21 28 0 text {Equip no: D-100Descr 1: COLUMN RECIEVERDescr 2:}}Now comes the hard bit, in the bold section above you will notice that there is some text Equip no: P-102B I want the user to be able to enter in a form *102B* and for it to return -32768 21 12 0 which is after lbl{ and before text.Now obviously I could loop through the whole file to do this, however I am very concerned about RAM usage and also the time it will take to do this. Obviously the user could use this search option over and over again and therefore we would be searching the same file over and over again. One of my thoughts was to read the file once and output the content in an Access Database table and then use SQL to get the information? However would the user require Access on there machine to be able to do create the database or could I just ship a blank Access database with my app and then copy this and populate? Also I am not sure if Access is the best database, obviously I don't want people to have to use Oracle of SQL as this would require server configuration etc. but are there better free databases out there?

I have to write a program that allows a user to input DVD info such as DVD Name, Year produced, Running Time, and Rating. The user then clicks a menu item "New" to save that info to a file. Then the next time the user inputs new DVD info it has to append the new data to the same file. (I got this far and everything is working writing and appending data)Next the year has to be able to search by DVD Video name and it has to print the info in the text boxes on the form, if not found then a messagebox should say not found. When I use the sub procedure that I have created to search the record it always comes back as record not found although the record in in the file.

I've got two text files. The first has got a list of certain keywords. Each one if these keywords are fed into a combobox. Now, when I choose one of the items from this combobox, I want to search the other textfile for the same keyword and read from that point to the next keyword. And then feed each line into a listbox. Perhaps I should use an INI-file for this purpose, doesn't really matter for me.
The textfiles have this structure;
Textfile1:
London
Oslo
New York
Hamburg
Amsterdam
The second textfile has this structure;
Textfile2:
'London'
Apples
Oranges
Pears
'Oslo'
Pasta
Salami
Monkeyballs
'New York'
Dada
Duda
Dadadish
Is this possible? The reason I want to do it this way is to create a fully dynamic system. One which relies fully on whatever information is stored in these textfiles. I'm gonna build pretty complex strings from these results later on. So far, I've got this to read the first file and add each line to the combobox:
Dim oReadMenuFunction as System.IO.StreamReader
oReadMenuFunction = IO.File.OpenText("textfile1.txt")
Do While oReadMenuFunction.Peek <> -1
Dim LineIn as String = oReadMenuFunction.ReadLine()
Combobox.Items.Add(LineIn)
Loop
