Searching For A File On A Drive?
Oct 29, 2011
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.
F.eks
I have 4 HD's and WOW is on the 3rd. I want this software to search all the HD's to search for Wow.exe.

I have a program that works I would just like it to be able to find the file with out me specifying the actual path. Because if it is on someone's computer other than mine the path might not be correct and it will not function properly. Here is the code I have done. The file it is looking for is of course names.txt. I have not been able to find much info on this.

I'm working on a program that is used as a tool to quickly search & Open CAD drawings on our network. I have it working for the most part, but it is very slow. Right now I have an ini file with the path to the Directory I want to search for Example "G:" I think the reason this is so slow, is because there are other folders in this directory that don't need to be searched. My idea is to add all of the paths I want the program to search in the ini file, but I don't know how I will have it search through this using vb code
want my ini file to look like this
G:A
G:B
G:C
G:E
So directory D would not be searched by the program because its not in the list.
MyCode
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim PathReader As IO.StreamReader
PathReader = IO.File.OpenText("C:ISOExplorerPath.ini")

I have an application and in this application there is a search option. I want the seach to search for all music and video files. I keep getting UnauthorizedAccessException error and I'm assuming its because my application is trying to access a file for witch access is being denied. This is the code that I am using.tbsearch is textbox and results is the listbox that the search results get added to.
Dim dirPath As DirectoryInfo = New DirectoryInfo("G:")
For Each file As FileInfo In dirPath.GetFiles
(tbsearch.Text & "*.mp3", SearchOption.AllDirectories)
results.Items.Add(file.FullName)
Next
Also, how can't I make it so that only the name of the file found is added, not the full path. I know that I could instead of using file.FullName use file.Name but then I can play the media file because the application wont know where to find it. Any code that I could use to add only the found file name to the listox? Perhaps I need another hidden listbox that get the full name and then the results listbox retrieves only the last part of the path?

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 was using the following code to check the file size of a data file on my local machine. Now the data files have been moved to a mapped network drive and this code no longer works. What do I need to change or how do I access file size on a mapped drive?

Dim FileSize As Long = MyFile.Length

I'm running the following WMI script to get the associations between drive letters and physical drives on the system, but for some reason it omits CDROMs/DVD-ROMs. Can someone tell me how to get those as well?
Code:
ComputerName = "."
Set wmiServices = GetObject _
("winmgmts:{impersonationLevel=Impersonate}!//" & ComputerName)
Set wmiDiskDrives = wmiServices.ExecQuery _
("SELECT DeviceID FROM Win32_DiskDrive")

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 have a program that allows the user to enter a drive letter into a text box. The program then takes the letter and find the physical drive number (i.e. deviceharddisk3..). It then stripes out everything and leaves me with the number 3.
In VB6 I used mDrive.bas from vbAccelerator.com and it worked perfectly. I have been all over the internet and back and cannot find a solution written in VB.NET.

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 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.

The drive is connected via USB and the problem I'm having is that, periodically, while my code is executing, the usb drive seems to disconnect and reconnect. (Nothing to do with the program, but the drive itself).I want to find a way to prevent these temporary drive reconnects from interrupting my code. IE, i want to insure that whatever read or write that is requested is actually executed even in the case of a temporary drive interruption.

I am trying to get the physical drive (device) number from the drive letter. If the user inputs the drive letter C the program will find the associated physical device number. For example if I input C then the result needs to be \Device\HardDrive1\... Some call it NT Device Name; I think. I have the code for VB6 from vbAccelerator, which works perfectly, but it does not work in VB.NET. My question is there a simple way of pulling the drive info that contains the drive letter and the physical device number. I have searched the internet and found nothing for VB.NET. I would post code but I have nothing for .NET.

I have a program I am converting from VB6 to VB.NET and I am stuck at the very last piece of code. I need to determine what physical device number is associated with the drive letter.
The program takes the drive letter from a text box and goes and finds the device number (i.e. deviceharddrive3...) and strips out everything leaving me with the devicer number; in this case the number 3. I have searched the internet to and fro and found nothing in VB.NET.
My program in VB6 uses a .bas module from vbaccelerator.com called mDrive.bas and works great. I can't figure out how to convert it over to VB.NET.

I'm creating a small program using Visual Basic 2010 Express. I'm planning to place the program on a CD, along with the files I want to run. The program will have command buttons, and each button will open a different file.For example, if there is a file on the CD named ReadMe.txt, the user will be able to open it using the program, which is on the same disc as "ReadMe", by clicking the corresponding button (or link) ("ReadMe".)The problem is, that I don't know what the CD drive letter will be. Is there a code to make the program run a file which is in the same location as the program?

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
