I have found a few examples of this. basically instead of it watching only one folder, how would I have it watch any folder that's not named system32? I know I would need something similar to this:

I'm having a problem trying to work out how to watch a folder for changes. This is how far I've got:
Class MainWindow

Private Sub Window_Loaded(ByVal sender As System.Object, ByVal e As

The problem is when a change occurs in the folder the program exits with no error code. I've read a few related posts and I know it has something to do with thread safety. However I've no idea how to make this program "thread safe".
We can watch the file action by FileSystemWatcher but it give us to only create,rename,delete or replace action report, can we get file access action ? for example when user double click any file? or when run any application?

Issues i am facing
1. Its not working on Samba Server
2. I need it to watch on predefined times only. (i.e., may be every 5 Hrs)

Does the File Watcher class in VB.NET only watch one folder? Or can I have it notify me of any change in the whole drive?

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.
View 4 RepliesJust moved from VB.NET to C#.In VB to connect and Event Handler to a Sub we use the Handles clause.From what it seems, this do not exist in C#. After creating a simple application with a button I realize that Window Forms Designer automatically created an EventHandler to my button1_Click function (after I double clicked it), in Form1.Designer.cs with this code:
this.button1.Click += new System.EventHandler(this.button1_Click);
But, in VB, the WinForms Designer create the Handles clause in my class, in the function header. So, C# create the default EventHandler in designer file, while VB creates in main class where control resides.
This is my first attempt at creating a Winforms application, and I have been developing in the .Net Framework (Silverlight, ASP.Net, WPF) for about 6 months. So, my appologies if this is a newbie question.
Basically what I am doing right now is taking the drawings of a stylus-based input, and storing them into an image field in a SQL Server database. Then, in another form, I go and get that image out of the database, and load it into a picture box. It works, but it is rather "sloppy" how it got there.When the user clicks save, it stores that image into a temporary folder, then converts it to a byte array and throws it into the database that way. Then, it deletes the file from the temporary folder. When retrieving it, it pulls it out of the database in a byte array, then converts it to an image in a temporary folder, thus displaying it on the form.
Is there a way that I can just bypass the storing of the file onto the user's harddrive both times, and go from byte array to picturebox?
I have a thumbnail control where I am adding Images using openfiledialog and after adding it automatically scrolls down.
So I would like to stop scrolling the scrollbar and just append the Images.
I have tried using this code:
Thumbcontrol1.VerticalScroll.Value=0
It worked fine but the scrollbar is at the bottom and it shows me the first row of Images.
And this is my second attempt by doing this way:
I have just set the autoscroll property to false and it hides the scrollbars and I'm stuck with this so how do I scroll the remaining Images?
And Is there any other method to hide scrollbars and just scroll the Images using mouse? Or any other simpler way to get rid of this?
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 4 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 RepliesDoes anyone know if there is a way to determine if a drive is local or a network drive?
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.
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.

I am using the following code to get a list of the letters for each drive on my computer. I want to get the drive letter of CD Drive from this list. The code I am using to get list is as below:

Is it possible to check if a Logical device gathered through a WMI search request is a CD/DVD Drive? Right now, I can get the path of every Win32_LogicalDisk through WMI, but E: (for me) is my DVD drive and unless there is a disc, my program fails because it tries to count the number of folders/files on the disc.
Ultimately, I'd like to be able to tell if it is a CD/DVD drive then check to see if there is a disc there before I do anything else to it. Can it be done using WMI?
I have a function that copies files from a CD to my HDD:CopyFiles(CD_Drive, FullPath & "")
The problem is that the Drive letter "I:" is not consistent. Sometimes when I connect and disconnect external devices, the CD Drive letter changes and then my code doesn't work unless I open the project, change the letter "I" and recompile.What code can I use that will ALWAYS detect my CD Drive, regardless of the drive letter? (Like for instance, NERO will detect and burn CDs regardless of the drive letter)

View 12 Replieshow to open an .exe file from a that is in a certain file, what i am trying to do is create a program that will be portable-via jump drive or cd drive, the reason i feel stupid is that I did not realize that visual basic and vb.net are two different animals- I was trying to use app.path for days- then came across a post that set me straight that I can not use it.[code]
View 4 RepliesI have created a form that I would like to run from a jump drive, or cd drive, were the drive letter will never be the same-
Application.StartupPath is the answer I have come up with- Implementing it is difficult for me- all the examples I have seen retrieves the path and imports it to a textbox. What I got is a form will start a .exe of a portable program- ( that will be located on the jump drive, or cd)
I have created a form that will -when a button is pressed- execute an .exe to a program that will also be on the jump drive. how to do this from start to finish on how to run an .exe from a file that will not ever be located on the same drive-
I should add I'am using visual studios 2010, visual basic.net
What is wrong with this code...... it should remove all folders and files on the "J" drive i am using win7 and would like to just format the drive

I know in the older versions of Visual Studio, there was an "Add Watch" option where you can choose to stop execution when the value of the field changed. I am using VS 2010, and I can't figure out how to hit the breakpoint when the value of the field changes.
View 2 Repliesi have a variable that changes every few minutes and I am trying to find out the best way of going about 'watching' that variable and simply changing the text of a label based on the returned variable
so pseudo code on a button click at the moment i have a function that returns this variable
label1.text=myfunction.getName()so this works fine , It seem ugly to have some kind of sleep function that loops every couple of seconds to run myfunction.getName() every 2 seconds , as a bit of a newbie , I am just wondering how I can set up a function that basically says 'when myfunction.getName() changes , then change label1.text'
