I have a system that detects USB mass storage devices. I have a "list of items" listbox (ListBox3) and a list of USB's (Listbox4) When Button4 is pressed it will transfer all files in listbox3 onto the mass storage device selected in listbox4
View 29 Replieshow 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.

View 39 RepliesI am trying to come up with something that will let me obtain a unique ID of some sort for most types of storage devices. These can be USB thumb drives, SD cards, external hard drives, etc.
I have run across this:[code..]
But I can't find anything similar within .NET. Can anyone point me in the right direction?
My end goal is to be able to define specific hardware storage devices, and then have my application auto-detect them when they are plugged in.
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.
I want to write a program that will log all the files that has been copied to removable device. I tried to work with FileSystemWatcher but I didn't get the result.

I am looking for some API or OCX or any other method to copy the existing file from Hard disk to the USB storage device.for that i would have to perform the following checks :
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).
I'm just testing things and seeing if I can get things working and if I can then I want to try and develop this into something more. So far its just a simple button1 finds all files with extension of .mp3 in C: and displays all the findings in a listbox. I then want to use button2 to copy or move (I want to see how to do both) all of the files that are in that lisbox to a directory of my choosing. Here is what I have so far.

View 5 RepliesI have been creating a program that copies and moves files from folder to folder; I am using this sort of code;
fileToCopy.CopyTo("path here...")
or
FileToMove.MoveTo("path here...")
My problem is, when I am copying or moving a large file, It's taking so much time and my program is hanging until all the files are completely moved or copied. How about, using a progressbar instead, so that the user will be able to see the progress of copying and moving instead of the program freezing?

View 3 RepliesI'm using an xsd file for a couple of my data sets that I'm using to read access databases. While this is great, I just got a new requirement that allows the user to change the link to the access database on their computer. Is there any way to allow them to set the path while still being able to use the xsd files, instead of doing it all through code?
View 2 RepliesSuppose I have two events:
Public Sub Control1Updated() Handles control1.TextChanged
control2.Text = SomeFunction(control1.Text)
End Sub
[code]....
Basically the pairs of {control1.Text, control2.Text} and {control2.Text, control1.Text} should be the same. If control1.Text is changed to let's say "a" then control2.Text is ALWAYS "b". If control2.Text is changed to "b" then control1.Text is ALWAYS "a". How do I achieve this with events without going into an infinite loop? [the best I can think of is to make a check if the other control.Text is already the desired value].
I'm creating a VB2010 application which will require a connection to MSSQL. Should I Install SQL 2008 on my computer then use MS SQL 2008 as my data source or skip installing SQL 2008 and use MDF instead?
Also the program must have the following requirement
Program must use SQL as their database source End user must not install SQL server on their machine Program must be able to update (sync) the local SQL database from SQL server on the web. (User will have option to delete everything on their local database and load everything fresh from the server or to merge the update with existing data) Programs will (most of the time) run in an offline environment. When the user have access to internet they can update the database The program must allow user to add,edit, delete their local database while offline Only certain user (authorized user) can update their local database back to the serverC
Is it possible to created a program that meets all the above requirement ?

I as seeking to move 10 file every 10 minutes from one folder to another using .NET (vb c#) I am was thinking that i could of achieve this with LINQ query, but i cant get my head around this would there be a solution with LINQ or otherwise that can select the last 10 files form or top 10 files. so that i can move only these files from Directory1 ( the big pool of files) into director 2 ( a smaller more manageable pool of files).If all fails- then i wll manually have to copy or cut to at a time.
View 1 RepliesI am making a program that takes files (inside their folders) and copies them into a selected file path. For example, I plug in my jump drive, run my program and it copies my files on the jump drive over to my PC. Now my program does this but it takes the files inside each folder in my jump drive instead of creating a folder for each one in my jump drive. The result is a mess of files in the selected pathway in my PC.I went and created variables in My.settings so that you can save the file path even after you close the program. I just want the program to copy the folders(with the files in each folder) in my jump drive and move them over to my PC.I am using this program copy the files from my jump drive over to my PC, because I save a lot of work on my jump drive and I need to back it up often.

View 4 RepliesI am having trouble opening my vb.net 2005 project from a backed up copy on a hard drive. The original files are on my old XP computer which I no longer have access to. I am trying to open the project in vb.net 2010 on Win7. I have converted the project to vb.net 2010 and when I open the file, nothing shows up, when I try to open them, it tells me the form isn't found in the project directory because it's been moved or deleted. I know that the software on the hard drive didn't back up .exe files, I'm not sure if it did back up other kinds of files. I don't want to restart the project because I've spent over a year on it and have written over 3000 lines of code on it.
