View 14 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 Replieshow to code an administrator and non-administrator account in VB.net to authenticate a specific user account when mounting his removable device? what will we use, to provide a special key on a specific flash drive?
View 1 RepliesI 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 wondering if you it is possible to make your usb flash drive to be like a key for your vb.net program I can't really put it into word the description of it so I will site an example here's my scenario my program has a textbox where you put the password on it to make the program usable but i want instead of typing on it you insert your flash drive and it will automatically insert the password in the textbox and make the program usable.

View 3 RepliesI 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.
View 1 Replieslately, 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, .
View 7 RepliesI have an App where I update data on a USB Flash Drive and I'd like to add a button that would make it "safe to remove the drive." Is there vb code to execute or emulate the "Safely Remove Hardware" icon on the taskbar?
View 1 RepliesI 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.
View 3 RepliesI 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.
View 1 RepliesI 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?)

View 7 Repliesi 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.

View 4 RepliesI 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 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.

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.
View 1 RepliesI 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.
First off a short background of the project I am working on- I am developing a program that will be run off removable media (i.e. USB Flash drive). This will be a �virtual desktop� which you will be able to take with you and have the same �desktop� on any system. As we know drive letters can change with each host system the drive is plugged into, I need to be able to determine the path for the flash drive and access a specific folder ( i.e. My Documents)
I have an picture box(representing the icon) placed on my form (form1) and when I click the icon I want to be able to open and view the a specific folder from the portable drive. I need a click event that will determine a dynamic drive letter for a directory on the removable drive and then open that directory in an explorer window.
