I've developed an application in vb.net that can run from a usb drive. But i need my app to work only from that usb in which i distribute it.
If someone copies it to other Drive/USB, it must not work. Do u know how to implement this?
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

I know, looping through is fast enough. But the search program "Everything" can index my entire C: drive in about 15 seconds. Does it read the MFT or something? Can I do this easily enough with VB.NET? Or at all?

i have a NAS drive that is mapped to my system..My application will copy files to the drive but the only problem is the drive has a sleep function on it therefore when i try to copy files to it and it is in sleep mode, it says the folder does not exist (drive still in my computer but just with a red X on it)is there a function to make ir ready ? the only other way to do it is to double click the drive icon in my computer then it wakes up... but id rather not do this as its a pain.

View 6 RepliesI'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)

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'm creating a WPF application in VB.NET with the 3.5 Framework. (If you provide an example in C#, that's perfectly fine.)
In my project I have a Template for an MS Access database. My desired behavior is that when the users clicks File-->New, they can create a new copy of this template, give it a filename, and save it to their local directory.
The database already has the tables and some starting data needed to interface with my application (a user-friendly data editor)
I'm thinking the approach is to include this "template.accdb" file as a resource in the project, and write it to a file somehow at runtime?

I have a mdicontainer form that summons forms. My problem is when the a user clicks again the menu for that form, it also make another instance of it.
What I did is declare a public class with a public variable on it ex: Boolean isFormOneOpen = false. Then every time formOne opens, it checks first the global variable I declared a while ago if it's false, if it is, instantiate an object of a formOne and then show it. Otherwise, do nothing. Very static, imagine if I have many forms, I have to declare a variable for each form to check if it's already open. Maybe a method that accepts a Form? Or any more clever way to do this.
in vb 2008 express this option is available under application properties. does anyone know what is its function? does it make it so that it's impossible to open two instances at the same time?

I've managed to make some single dimension array lists but I can't figure out a multi dimension arraylist.
Here's what I'm trying to do:
I have a database (mdb) with 5 columns that I want each row to be in an array list.
In PHP what I'd typically do is:
$array[$field1] = array($field2,$field3,$field4,$field5);
How I do the same in vb.net so anytime I need to fetch an item for a specific for the row1 I could call it?
For a single dimension I could do the following, but I can't figure out how to add more fields to a single array row:
Dim tmpArrayX As New ArrayList
tmpArrayX.Add(field(0))
tmpArrayX.Add(field(1))
etc...
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.
The 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 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 14 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.
