Read Files From An USB Mass Storage Device?
Sep 9, 2009
how to read files from an USB mass storage device. I have found plenty of posts regarding drive letter detecting and reading the files. It's OK, but what about a device, where no drive letter is assigned - e.g. my mobile phone is visible under "My Computer" as "Mobile Device". The same situation it with my MP3 player. It's visible under "My Computer" as "Sansa device". Please, could anybody help me? I need to enumerate USB devices, identify, which ones have a file system and finally, I need to read/write a file to the file system.

I'm trying to access a USB Storage device, however the device although appearing in the commputer / Drives section, is not allocated a Drive letter, thus when I itterate through the attached drives link text it does not appear, I've taken the "Location" from a file on the drive (properties) and it comes up as COMPUTER/Q1/Datacasts but this doesn't work when I pass it to the FileInfo Object (network drive cannot be found) And I'm at a bit of a loss at which way to procced

Is it possible in VB.NET to get the directory of a file copied/moved to a removable storage device?
For example, I have msword document on my desktop and move it to my storage device. A dialog box will appear or anything that will show the directory of the document.
The idea is whenever you move a file into the specific device, it will automatically processed. I will be using this to compress a file automatically when it is moved or copied to the storage device.

1> Check for the plugged in USB devices.
2> Find out for the available space(2GB) on each.
3> Prompting a message to user on which drive he would like to write that movie file.(As At a time i want to give only 1 disk write only.
4> after selecting the Drive, and pressing OK, i just want to copy the selected file from HDD to that Device.
Now For achieving this , i just need a reference of any Available API or OCX or any other method available in VB.net?

I'm just getting started with Visual Studio (2005), and my aim is to write a fairly simple application in Visual Basic that will need to store some data to disk.What I really want is to be able to send the application to the end users (xp, vista, win7) and have them just be able to use it without having down download all kinds of extras. For example I'm guessing that if I use an SQL database in my application they will need to download SQl server express or some other sql downloadable?
If so is there a similar downloadable for MS Access?I'm just in the 'seeing how things work' stage at the moment and I don't want to waste time going down the SQL track just to find it won't actually work unless my users all download SQL to their machines (which they won't want to do).

My current program can read in a continuous stream of data when initialized and I can send a command to retrieve the devices stored data, I also have within the same program code that will read an XML file and populate from controls.
I have two separate idea's right now that I'm trying to merge into one
I want to read in XML and populate my controls. I'm aware of delegate and Invoke but I'm having a hard time working them into my XML portion or the opposite "working my XML into my serial port class".

I am trying to read data from an external device using MSComm control but the problem is I am getting wrong data. I am recieving 1 byte data but the first three bits are wrong so anything greater than 31 sent from the external devices is recieved wrongly. eg. if I am sending 63(111111) from the device then the input from MSComm control gives me 159(10011111).Due to this reason I tried SerialPort from .Net framework and was surprised to see that it is working properly.

I have run into a problem with a couple of the "Sync" applications I wanted to create. In both instances, I am trying to connect a Portable Device to my computer and access it using VB.NET. One application would pull the pictures in from my camera, rename them, and put them in folders according to their date taken. The other would place the podcasts I have downloaded onto my Mp3 Player. I have the logic for both so that if I run it on two Windows directories, for example (C:Source and C:Destination) but when I try to access the Portable device using a directory browser, the "OK" button is disabled. Is there any way to access the directories on such a device?

I want to develop an application which can Write, Save, Read text files(or html files) What I want the application to do is. When I open my application I can write stuffs and then it will save it to my hosting/server. Then, the application will read the text which I already save.. So far, I can only make the application read it by using WebBrowser control and navigating it to a specified URL. Example: [URL](or message.txt) Which I modified from the website not from the application. I want to modify the text or html files from my application.
