The following code opens a Word doc and fills the data as designed. When I exit from it, the WINWORD.EXE process keeps active. If I execute the code a second time and exit from it again, a second process of WINWORD.EXE gets added and stays active. The example shown at url... doesn't produce the same problem. Obviously I'm not exiting the code as I should but I fail to see where.[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.
I'm using System.Management to start a process on a remote target via WMI like this:
InputParameters("CommandLine") = "executable here"
OutputParameters = ManagementClass.InvokeMethod("Create", InputParameters, Nothing)
This kicks off the process and my code continues to run, but I need a way of monitoring that process and not doing anything else until it finishes. Is there a simple solution? I'm hoping there's something similar to Process.WaitForExit like there is when creating a local process.
We have an application that allows custom UI and interaction via SDK. A DLL is developed for this purpose using VB.Net and the SDK. An object variable refers to the application and there are some other object variables for components within the application.

View 3 RepliesI'm not asking how to exit the program( dispose() ) instead I have a program that checks if a certain process is running and if so it displays a message box, stops the process and (Should) exit the program. If the process is not detected then the program loads normally and opens an external program. My problem is that it stops the process and still runs the program. How can I fully stop the code and exit my program?

I'm having a bit of a problem getting my application to close properly. Basically I have one main form from which all other forms open. If a user tries to close that main form, I want to bring up a MessageBox asking if they want to exit the application.However, when I try to do that it asks the question twice. It seems that the Application.Exit() is triggering the FormClosing event again for some reason, but I don't know of another way to exit the application. BTW, the main form isn't the startup form so I can't use the option to close when the startup form closes.
View 9 RepliesNow I have a sub to validate a bunch of textboxes and combo boxes.I previously used many IF statements to validate and pop up different messageboxes and Exit Sub in every IF statement.But I heard that too many Exits will decrease the efficiency and they were not recommended to use. Instead, nested IF is better because it will let the process naturally go to the end.Then I found out that if I use nested IF,it will be hard to read, since messageboxes are all separated from conditions.

View 5 RepliesI 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).

The void pointer corresponds to enums or structures. I have to get this structures/enums on the vb.net dll end. I have mentioned about using pipe. My question is as what type the pointed to data can be send over the pipe so that I can easily handle the received data at the vb.net dll end.

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.

View 9 RepliesI 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 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 a procedure (parent process) that starts several processes (child processes). The child processes calculate several array variables. How can I pass those arrays to the parent process? At the moment, the child processes write the arrays to a streambuilder and the parent process reads the stream. Is there a better way to do it? Is it possible to have the child processes write to RAM memory and have the parent process read from there? It is like declaring a global variable in the parent process and give the child processes access to it.
View 4 RepliesHow 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.
Whats happening is I run the code below and get the following error "The system cannot find the file specified". I've read that with UseShellExecute set to false that you can't use WorkingDirectory.
