VS 2010 Launching New Process & Detecting If That Process Has An Error Message
Nov 19, 2011
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")

We have an application that self-updates using a Laucher.exe process which copies down new App.exe and DLLs from a server then runs them in a separate process. This was all working very well until the arrival of the Windows 7 taskbar... Problem is in Windows 7, if the user pins the Launcher.exe to the task bar (by right-clicking the shortcut to Launcher.exe) then this happens... When you start the program the "pinned" taskbar icon momentarily gets focus while the launcher is running but then a totally separate new icon appears when App.exe is running. If the user then decides to right click the icon from the running App.exe and pin that to the taskbar, they bypass the application update part of the process.

I would like to launch a command line exe I created. For now it's a test program that writes Hello World to the console. I can launch it, but the shell window it displays it in only stays for a split second.
I know I can add a line to my console mode program (readline). But I would like to control it from the process launch. I will be using console mode programs that I did not write myself, and many of them don't stall the output. I can't find the right properties and methods to control the default shell behavior!

i am trying to open an external executable file during runtime using a process component and the process.start() method. I've been testing out my code with various executable files on my C: drive....some work and some do not work. I've been able to successfully open Adobe Acrobat, Microsoft Excel, and Notepad; however, when I try opening various other executables the following exception gets thrown:
A first chance exception of type 'System.ComponentModel.Win32Exception' occurred in System.dll
I cannot figure out why some programs open just fine while others cause the above exception to be thrown.

How can i access a file through FileStream which is being used by a window service. Actually i am trying to access a file which is also being used by our window service. I need to read data from this file. I am using below code but also getting following error:
Code:
Dim fs1 As IO.FileStream = New IO.FileStream(psPath, IO.FileMode.Open, IO.FileAccess.Read, IO.FileShare.Read)
Dim sr As IO.StreamReader = New IO.StreamReader(fs1)
sData = sr.ReadToEnd
Error: The process cannot access the file 'FILENAME' because it is being used by another process.
I tried changing FileShare.Read parameter to FileShare.None but it didn't work out. I also read below post which says that it is not possible but i think there is a way to read it like if you open a file through Firefox but still window service is accessing it.

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).

I have some coding which edits my text file and saves two versions, the first version removes all multiple space with one space and saves it as a text file and the second replaces the spaces with a comma and saves it as a csv file. The problem I have is however later on when I run other code using the saved text and csv files, it looks like the processes are in use. I get the following error:
The process cannot access the file 'Path' because it is being used by another process.My actual coding:
Private OpenFileName As String = IO.Path.Combine(Application.StartupPath, "TextFile1.txt")
Private SaveFileName As String = IO.Path.Combine(Application.StartupPath, "TextFile2.txt")
Private SaveFileName2 As String = IO.Path.Combine(Application.StartupPath, "TextFile3.csv")

My app starts an On-Screen Keyboard process like this:
Dim PID as System.Diagnostics.Process
:
PID = Process.Start("C:WindowsSystem32osk.exe")
:
[CODE]...
It seems to work 90% of the time. However, sometimes the PID.Kill() fails because it says the process already exited. At this point the OSK is always still there on screen. Yes, I know my code should be testing to see if the process is still running before trying to kill it, but given that the OSK is still on screen..

I have a program that starts another program after setting the regkeys basically the program continually syncs the calandar of outlook and another application.I set the regkeys than launch the c:sync.exe app. I have tried a simple process.start and launching the process as a thread and they both do the same thing: The other process starts and works as it should but my main program goes "White screen" or "not responding" until the process.start has exited.
I want the process.start to run in the background so if users click in my main app it responds and truly that they can access the context menu of my main app from the taskbar while the process.start is running.

I have an issue using Process.MainWindowTitle,Process.MainWindowHandle on some older VB6 applications. After Process.Start I use Process.MainWindowTitle to display in a listbox. The MainWindowTitle returned is not the Window Title but in fact the Project name of the VB6 exe.? I also store the MainWindowHandle to use the ShowWindow and SetForeGroundWindow API's. It would appear that the ShowWindow API does not work, but the SetForegroundWindow does. ie: if the VB6 app is minimized, showwindow does not restore, if it is NOT minimized setforewgroundwindow sets it to the foreground. The exact same code does work correctly for any other .net exe or notepad, only on these vb6 programs I am having a problem.

I have made a small program which loads a file into a listview when somebody presses the load button on the form. The user can also put information in the listview by filling in some textboxes and press on the add button.So now the weird thing is that if the user loads an empty file ( With no information in it ) and presses load on the form and after that tries to add information to the file you get a "The process cannot access the file '" because it is being used by another process" error.
The code for the load button is as followed: ( So here accountfile 2 is loaded )
Dim BinFormatter As New System.Runtime.Serialization.Formatters.Binary.BinaryFormatter()
Dim FS As System.IO.FileStream
