I'm trying VB.Net 2010 in w7 on my new 64-bit PC. Thought I'd start with a media player. My problem is the exception that arises when I search for all MP3s on a drive. How do I get around/deal with the System.UnauthorizedAccessException' exception? A quick sub-program that I've written to illustrate the problem is:

I want my program to find the disk drive. I just do not know how to find it programmically? Can anyone help, please? This should be pretty easy, right?
View 12 RepliesThis is not for school assignment it is for me trying to create a dynamic small application.
I need to run an application from a pen drive. Since different computers call the drive by different letters I need to discover the drive letter and then check for a folder existence. If not there I will make the folder(I know how to manke the file) and ftp from network to the folder then run the items. If it is there I just run the items
My difficulty(probably due to brain freeze) is how to get the drive letter.
Is it possible to find a drive's letter given one of the following two?
1) SCSI Address (eg 0/0/0)
2) NT Device Name (eg /device/CdRom0)
i'm trying to list out the what to pick when using the perfmon counter, physical disk. when you look at it in perfmon, it shows for example, 0 C:, 1 D:. I see how to get the drive letters avaliable on the sytem.. how in vb.net to get the disk id. i want to get a listing of all the hard drives on the system, both their ID and the drive letter.

Im trying to create a program to gather information about users pcs. So far I have been able to gather thigns like the os, processor, hard drive size and graphics information and I was just wondering how I would be able to collect the name of the motherboard they are using (or model) and the make of the hard drives in their machines.
View 1 RepliesI 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.

What is the best and fastest way to find the exact location(Drive/Folder) of a specific file, without scanning the whole drive. Right now, I am using those two instructions to locate EXCEL.EXE so I can properly call it with a shell command.[code]It is quite a long process, and I have to deal with some access denied folder like System Volume Information. I am quite new to VB programming.

View 9 RepliesI am currently setting up my own media player and so far there is only one thing that is making me very unhappy/frustrated. I have searched google so much and still couldn't find the solution. Here is my problem. I'm trying to import MP3s into a ListBox and have that as my playlist using this code:
For Each Song As String In Import.FileNames
playlist.items.add(Song)
Next
The only problem with this code is that it displays the song's full path in the list box. What I'm trying to do is just bring in the name of the MP3 without showing the path and still have the song play.

I have created an ASP.NET Website using VB.NET ASP.NET 4.0. Thing is, I want my visitors to hear some nice piano music as they browse my site. Now I don't know how to embed and play mp3s on an ASP.NET Website. So I need help with that.Further, if the website visitor changes pages, music should pick up where it left off before the page change. how to do this?
View 1 RepliesI'm trying to make it so one can search the title of a song:
Let's say 50 Cent - Many Men.
One hits search, and it searches certain mp3 sites for the song, collects the names of the file name to be downloaded from certain sites, drops them into the listbox, and one can right click the song title extracted in the listbox & click download or save.
I already have code to read ID3v1 and v2 tags. That's not the problem. I open an IOStream, locate the ID3v2 header and pull the bytes out. Handling unicode was a bit of a sod, but I got it working.
What I don't understand is how to remove an ID3v2 tag or write one out. ID3v1 is easy - just truncate the file, then append some bytes. Simple. But ID3v2 tags don't have to be at the start of the file, do they? It's conventional, but by no means mandatory. If I just crop the entire ID3 out of the file, and close the gap, will that work? And then, to write my own tags, should I just write the bytes to the front of the file? Or do I need to update other bits of the file so the player will know where the audio data has moved to?
Also, do I need to use unsynchronisation? How can I tell if I need to?
I've looked on CodeProject; I've googled; and I've read the specification on id3.org - which, by the way, is less than clear! For example, it says that the "Extended header size" can be 6 or 10 bytes in length. So um....how am I supposed to know which one? Is there some magic way of determining how many bytes this value is being stored as?

View 1 RepliesI'm working on a program to catalog MP3s (I know, it's a tired thing that's been done to death), and want a better way to determine if a file has previously been added to my database. I have two datasets that are structurally identical. The first dataset is populated from the database and the second is populated via the application during the scan.
I then compare each record in the second dataset to the first with the following code:
Private Sub CompareDataSets(ByVal dsOriginal, ByVal dsNew)
Dim dv As DataView
Dim sFileName As String
Dim sPath As String
Dim bgFileSize As Long
[CODE]...
This method seems terribly inefficient and I'd much prefer being able to do a join of sorts off the two datasets and delete all records from the application populated dataset where there is a match.
I already have a code to play music files in the same folder with the app..

I would like to find all the "About" files of all programs stored on my hard drive. If you open a program, click on help and select "About". It provides the name, version and date written etc. I would like to extract and store in DB. The store in DB part, I have no issues.

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?

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 want to make a tool that will assign a USB pen drive a drive letter, I am using WMI to acknowledge the device being plugged in, I can pull the deviceID, name, etc now I just need to work out how to assign the device to a drive and I just cant figure it out
View 4 RepliesThe 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.
View 1 RepliesDoes anyone know if there is a way to determine if a drive is local or a network drive?
View 1 RepliesI 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.
