Am trying to achieve a couple of things: merge a bunch of individual text files into a combined file, move the files that were combined into a new folder. I have assigned each of these tasks to a method. Something in the first method is hanging on to the file, even though I am closing and disposing the stream reader - but I can't figure out what. I know that a process from the first method is hanging on to the file because when I comment out the first method, the second method moves the files without a problem.
EDIT The first method is returning a value for new big file. This is passed as a parameter to the second method. When the second method tries to reference this file, that is when the program throws the error (5th line from bottom) Most posts on SO advise closing/disposing IO objects, but I am already doing that. They also advise using a third party tool to investigate what process is hanging on to a file, but I already know that it is the first merge method (because when it is commented out the program runs).

I am working on a small VB application that listens for commands sent from an Android app.
One of the functions is to extract an archive. I am familiar with how to listen for the unrar process to finish, so I can display a progressdialog on the phone while the extraction is happening, and clear it as soon as it's done.
BUT ... if there is an error/alert from WinRAR, WaitForExit() never gets called because WinRAR is still sitting there open until I click "OK" on the MsgBox.
For Example ... if you try to extract a file that is not actually an archive... an alert will pop up saying "No Archives Found", and basically everything is halted on the VB app and the Android app, and the Android app just sits on a progressdialog saying "extracting..." until you manually hit "OK" on the computer.
As you can imagine, this is a problem if the whole point of your app is to NOT have to go over to the computer.
So... I am wondering if there is something similar to WaitForExit() that will wait for an error and allow me to close out the alert and let the process end.
Here's my Sub for the UnRar command:
Private Sub UnRar(ByVal WorkingDirectory As String, ByVal filepath As String)
Dim objRegKey As RegistryKey
objRegKey = Registry.ClassesRoot.OpenSubKey("WinRARShellOpenCommand")

I am working with saving and deleting images. What i really want to do is check and see if an image exists in the destination folder and if it does automatically overwrite it. i couldnt figure that out so i figured i would look to see if the file was there if it is Delete it then write the new file..The issue is i keep getting this error.The process cannot access the file "FileName" because it is being used by another process.

I have written a windows service that is meant to launch a notepad when a specific action happens. The problem i have is that even though the service launches notepad, the actual notepad it self is NOT visible. I know that it has been launced because i can see the process in the task manager. By the way the process is listed as a SYSTEM process rather than a process under my user name (i believe that is because my process is a "LocalSystem" one).
View 4 RepliesSay that i have the following code that parse about 20k records from the DB.
Code #1
vb.net While reader.Read()
list.Add(If(Integer.TryParse(reader(0).ToString, 0), Integer.Parse(reader(0).ToString), 0))
End While
And then another code which does the very same thing but it seems to be a little cleaner.
Code #2
vb.net While reader.Read()
Dim storeowner As Integer = 0
Integer.TryParse(reader(0).ToString, storeowner)
list.Add(storeowner)
End While
This is what i am confused about; does the compiler creates a new variable automatically when i use the if statement without strictly declared variable? What approach is better in sense of performance?

I want the program I am making to show the cursors position on the process it is attached to. Sorry if this is a lot to ask for. Can you tell me how to.
1. Make a drop down menu with the list of process.
2. When i click on one of the processes, my program attaches to it.
3. When I move the cursor over the process, my program tells me the co-ordinates of the mouse on the process.
4. When i press F3, Timer3 Starts.
5. Make the mouse move to a co-ordinate on this process.
If it is too much to ask for, can you just tell me how to do 1 of them and hopefully someone else will tell me to do the others.
it is possible to see what process is running a file or see what files a process is using?

View 10 RepliesI am working on an application that needs to launch Microsoft Word, and then resume when the user closes Word. The code below should work, but it does not. I get an 'object not set to an instance of an object'

2 Dim P As New Process
3 pInfo.FileName = "C: estLLR.doc"
4 P = Process.Start(pInfo)

I put p into the watch window and it shows a a system.diagnostics.process in the watch after line2, but after line 4 it return to NOTHING. The process launches, but I can not monitor it any longer with lines 6 & 7. Is this a 'limitation' of Visual Studio 2010 or am I making an operator error?

Basically, I am just trying to close the thread/process after it's done.
Private psi As ProcessStartInfo
Private cmd As Process
Public Delegate Sub InvokeWithString(ByVal text As String)
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim psi As New ProcessStartInfo("m7.bat")
[Code] .....
I am trying to close the thread so once it's done, it closed for good and my form is closed as well. I tried Me.Close() which results in: "Cross-thread operation not valid: Control 'Form1' accessed from a thread other than the thread it was created on." Error.
Me.Invoke(New InvokeWithString(AddressOf CloseME), e) - Results in parameter mismatch error.
However, things like Msgbox("Done") works perfectly.
Dim movie As String = TextBox1.Text
Dim subtitle As String = TextBox2.Text
Dim box As New Process
box.StartInfo.FileName = "MP4Box.exe"
[code].....
When i click a button this code is executed. But it wont execute the command "MP4Box.exe -ttxt " + """" + subtitle + """" Why?
The only logical way is reading the file and creating Try and Catch?

im trying to start a process within vb.net as an administrator. I have succesfully impersonated an administrator from within my application, however when I try to process.start to access a UNC path it says login username or password invalid. This is not true because im running as the user who has permissions to access that unc path.
I was able to work around this, by using shell() instead of process.start(). However, with Shell() you can not specify a username and password, so I have to use the runas command. However, shell calls for runas, but runas requires you to enter a password in order to proceed to call the program your requesting runas to run. How can I programmatically enter the password into the runas.exe process as if I entered it manually.
If there is a way to implement this using process.start() instead of shell() please let me know.
This is what I have so far.

I'm just starting to use VS 2010 - not sure if this was available in VS 2008 - but I was reading about the Hosting Process you can start for debugging.This allows you to call methods and jump into breakpoints in them without starting the whole app running.
