Drive not Ready. I am using VS2003 VB.NET
I'm trying to create a Windows Explorer like application, when a flash drive is connected/disconnected the application detects it and does some stuff. This is what I've accomplished so far:
Code:
Private Const WM_DEVICECHANGE As Integer = &H219
Private Const DBT_DEVICEARRIVAL As Integer = &H8000
Private Const DBT_DEVICEREMOVECOMPLETE As Integer = &H8004

One thing that this code does not do is detect when the driver changes from ready to not ready, e.g. if a CD is removed/ inserted into the optical drive or a memory card is removed/inserted into the card reader. How can I accomplish that?
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 3 RepliesAll I am trying to do is write a simple program that will let me choose a directory and get a listing of all files in that directory and its sub-directories and show it in a RichTextBox. I got as far as being able to select the directory but when I click "OK" I get "access to c:documents and settingsstevedesktopmp3 is denied".The code I am using is listed below.

I'm running the following WMI script to get the associations between drive letters and physical drives on the system, but for some reason it omits CDROMs/DVD-ROMs. Can someone tell me how to get those as well?
Code:
ComputerName = "."
Set wmiServices = GetObject _
("winmgmts:{impersonationLevel=Impersonate}!//" & ComputerName)
Set wmiDiskDrives = wmiServices.ExecQuery _
("SELECT DeviceID FROM Win32_DiskDrive")

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.
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

View 2 Repliesi'm making a program that will be used Only from a CD, not ever downloaded to a PC.I just would like to have the user insert the CD into a CD-Rom Drive, and the program will Auto Start with a Splash Screen, then start/load the first windows form. The form will have some buttons on it for the user to interact with the CD, by either going to other window forms or by downloading exe files or zip files to the user's computer.
Also the form has buttons on it for the user to click on to bring up a PDF to be viewed.I have tried to do the Publish and found that it created a setup.exe...as in I think it wantes to install my program, and my program is not for installing. only viewing and interacting with and maybe downloading files from it, my CD program is never to be installed.I'm pretty sure I need to save or create my program as just an AutoRun, that starts when the CD is inserted and that is all I think needs to be done...so how do I just create a AutoRun Only version of my program, not a setup.exe?I will have a ini file to reference the AutoRun file on the CD, no problem.

View 3 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 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.
1)This is my code.. (below)what i am trying to do here is to insert username and confirmed password into a sql table called login via a pre created form.I have 1 textbox, 2 Maskedtextboxes and a button.
what i would like is if the passwords do not match in both maskedtextboxes for the system to throw out a message saying passwords do not match please try again..which then clears previous content and requires the user to enter details again. once details are correct and system commits the new user details to the table and throws up a confirmation message.

View 5 RepliesI'm making a hangman game (yes everyones starting point) and got the basics running. I've added so extras to it, such as reading in random words from a text file, only allowing capitals to be entered, an option of guesses the phrase etc. All very simple but a nice way to learn.
Anyway, I want it to show the letters that have all ready been entered between each guess. I want to do this by using an array and making sure the same letter cannot be entered more than once into this array.
So far i have the following:
Sub Main()
Dim GuessLetter As Char
Dim LettersGuessedArray(26)
[Code]....
and i do not know why. I want it to output the letter entered from the array "LettersStoredArray".
I have a report ready to print document, however you will make it stop reading when the records end up, give it displays this error:
Index was out of range. It should be non-negative and less than the size of the collection.Parameter name: index
I've tried an index = 0 to no avail, I think that has to do with the End print. Because I cannot make it stop reading after all the records appear on the leaves.
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.
