Create A Dummy File To Fill The Remaining Space Of A Flash Drive?
Mar 5, 2009
I was able to get some code working to create a dummy file to fill the remaining space of a flash drive. However, I have added a progress bar and can't figure out why it's not working. I declare a variable for the current value, min, & max properities of the progressbar and then increment it by 1 during each step of my FOR loop. However, I never see anything on the progress bar.
Dim CurVal As Integer
Dim RandomNumber As Byte
'Create the dummyfile to take up the remaining space on the drive
[Code].....

How would I go about using the Streamwriter in VB.Net to create a dummy file of 64 kb? Did a search of the boards, but didn't run across anything

I am starting a large project here at the office. This project will be an asset tracking software. If time permits I would like to be able to develop the system so that I could put a file on a flash drive and then insert that drive into a pc, run the file and then have all the information pulled automatically but this is where I have no clue as to where to start, how to pull this information automatically. I am also planning to have the ability within the program to generate and print barcodes and maintain the database internally, would I be able to do this with ado.net ? I maintain 4 locations, all together 15 servers and 400 plus nodes.

I am making just a simple program that will create backup dummies of all the files in a specified folder. All I have is 2 text boxes, A and B, and a button to do the magic. What I want is for the user to input into Text Box A the location of all the files, and in Text Box B place in the destination folder, then when the button is pressed it will get the name of each file using a loop and recreate a new file with the same name and extension in the destination folder

I am making a program that will allow a user to use any USB flash drive as a key, that when inserted, will automatically (upon validation, of course) enter login and password data into web forms, applications, and maybe even Windows Logon. But first things first: how to I detect when a USB key is inserted into the drive, for instance, perhaps just detect the last/latest inserted drive?
In addition, does anyone know if there is a way to directly identify a flash drive, maybe based on a serial number?, rather than validating it from a file on the device?

I'm developing a system info application. I've Searched all over internet and only found code for Free Hard Disk space, but not Total hard disk space.
The code should calculate the Total space of all the drives.

I have a program that I want to copy itself onto a USB flash drive or any other type of drive connected to the computer. Is it as simple as using the File.Copy method? Can I copy my own running exe?Basically I want them to copy it to a memory or external hard drive and then run it there on another computer. I'm not using any special controls and I know the framework will need to be on the computers it is run on.

lately, ive had a lot of free time and have been trying to password protect my flash drive in VB 2008. and ive figured out almost everything i want with it, but ive come to a bit of a roadblock. as of right now, ive got 2 accounts, but thats all ive done so far, because every account has like 3 if statements, and it would start to accumulate a bit of i made anymore. so, ive been looking into using a database, and having it retrieve the password and username from there. ive searched for hours, and have found a lot of little bits and pieces of code, but nothing that would work for my situation. Will somebody tell me how i would:
1: make sure that the password and username match in the database when i click the confirm button
2: add a new username and password to a database when they want to make their own account
3: save changes to the database when i log out and move to another computer
also, is there a simple way to log the date, time, IP address, and Username, put it in a text file, and email it to me? i would also like to know how to open a flash drive using its name, and not its letter, cause its a different drive letter on different computers.

I am trying to write an application which will have different functions depending on someone's security level, but my bosses have ruled out holding a users name and password information in a database due to risk of the database being hacked.So I have decided to use USB flash drives, which will have encrypted datafiles on them, and each staff member will be given one with their details pre-programmed onto them.However I am now stuck with detecting whether the device is present or not, I have thought I can continually scan the available drives and have each flash drive with a set volume label and when it arrives act upon it, but I don't want to keep continually scanning the drives, there has to be a better way than this, .

I am making just a simple program that will create backup dummies of all the files in a specified folder. All I have is 2 text boxes, A and B, and a button to do the magic. What I want is for the user to input into Text Box A the location of all the files, and in Text Box B place in the destination folder, then when the button is pressed it will get the name of each file using a loop and recreate a new file with the same name and extension in the destination folder.For example:
C:FolderX has 10 files in it, each with the same extension (.wav), each file is ranging from 10mb to 100mb (this size is irrelevant)
C:FolderY is empty
What I want to do is create each file from X into Y, however the files are all 0 bytes (no data inside them). I've managed to get a simple script that will do what I need but only if I specify the file name:
Code:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim Filename As String = My.Computer.FileSystem.GetName(TextBox1.Text + "test.wav")
Dim SaveP As New System.IO.StreamWriter(TextBox2.Text + Filename)
SaveP.Close()
MsgBox("Files Created")
But what I need is someone to show me how to create a loop that will do this for each file in the folder, without me specifying each filename.

I'm trying to make the progress bar to display the amount of free space C: has. I have successfully do so with my code which is:
Vb.net
Try
Dim b As String
Dim c As String
Dim dvr As New DriveInfo("c:")
b = CStr(dvr.TotalSize 1000000)
c = CStr(dvr.AvailableFreeSpace 1000000)
[Code] .....
As a last touch to this code I thought I would add a percent bar so it would look more professional. I did so with:
Dim Per As String = (c b * 100)
The problem is that it displays always zero percent why?

I am using VB from Visual Studio.net 2008. I need to understand how to build a VBScript or Application that will detect when a flash drive is inserted into a Windows XP SP2 system. Once the drive is detected, the VBScript/App must then automatically search for any available .ppt file (power point) located in the root directory of that flash drive. If the .ppt file is found, pptview.exe will launched opening the file in question.
This script will be located in the startup folder and will run until a flash drive is entered and then it should pause until the flash drive is removed and then start searching again. This is for a kiosk to be used at trade shows for a company I am working with. The company wants this to be simple and automated and only requiring that the user setup the kiosk, which has no keyboard or mouse, plug in a flash drive with a .ppt file on it. The system will then automatically load the slideshow and play until the system is shut down or the flash drive is removed.
I am pursuing this option because an autorun.inf file on the flash drive only adds another line item to the autoplay dialog. Although it may be possible to write a small script that will select that item, there is no guarantee that the user will have that autorun.inf installed on the flash drive in question.
Also it may be better to copy the .ppt file into a temp directory on the kiosk machine, so that in the event that the flash drive needs to be removed there is not data transfer taking place, minimizing the possibility of data corruption.
Most of the file handling I may be able to handle on my own, but it is the detection of the flash drive insertion and removal that is a problem. I am looking for some clarity on this point first. I may ask other questions later, but for now that is the biggest hurdle I have to cross. [URL]..

I recently wrote a program to copy files off of a hard drive with a corrupted copy of windows. I'm not sure how to make it run off of my flash drive in dos. I set boot priority to only boot off of the flash drive yet it will not run. I tried writing an autorun.ini file, which did nothing. I think i need to make a boot.ini file.

I move a VB project from school and home on a flash drive. At school drive mounts on E: at home it mounts on F:. I have 4 forms, Form1, Form2, Form3. Form4. Form1 and Form3 have incorrect file paths, it has the E:, but Form 2 and Form4 path change just fine when I move it from school and home.

I have a small project that contains three forms. The problem is that one of the forms is on a USB flash memory device(by accident)...the project works with USB flash memory device connected. I want to move the form from flash into the project on c: drive. However i think the project file (?) may keep the original path to the form and it still looks for it. The form in question has an icon which contains an arrow (is this indicating its else where?)

i have a question concering USB flash drives. I am building a Record Book with an Access 2007 database. When a user changes some information in the database i have built a procedure to create a backup of the database on a second hard drive. I was wondering if there is a way to find my USB flash drive serial number (either through coding or alternative ways) and specify that USB with that serial number as the location of the backup. As my program is at the moment, the backup is created from C to D. This can be a problem if on other computers there is no D drive or it's not a hard disk. By specifying the serial number to save the backup database to, should work on all pcs (theoretically). I am just not sure if this is possible in any way.

I'm *considering* a new project, but first I want to know if this is actually possible. Would there be a way for VB.NET to interact with a flash movie? What I'd like to do is fill out a field and click a button - or even just click a button inside the SWF. I wouldn't have access to the Flash source, so it would need to be all client-side.
