how to create an event which runs when a proccess finishes.
First, the program launches a batch file, so in the task manager, it appears as "CMD.EXE".
So, the event goes on when the CMD is over.
I'm not sure about what code should I use to do so.
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.
In an event handler of a tab chaged of a tabcontrol, I call a method asynchrounously, like this:
Private Sub tabDetails_Deselecting(ByVal sender As System.Object, ByVal e As System.Windows.Forms.TabControlCancelEventArgs) Handles tabDetails.Deselecting
' we pass pageindex so that we set the index back in case the validation fails

I am making a function of an application that when a function is called the application will close all processes that are owned by the user and were started after a specific point. My thoughts on this would be to trigger an event in my application every time a process is started and ended, and only if the processes is owned by the user, the event should get information (e.g. the process ID, name, etc) about that process and add or remove that information to/from an array depending on if the process starts or ends. Then when a function is called end all the processes in that array.

At the moment, I am writing a class that deals with starting an application in a thread, as well as being able to monitor the closure of the thread and process, and the creation of the thread and process through events. I have absoloutly no problems with monitering the creation of the thread and its internal process within the subs that create them. I placed notifications within the "myprocess_Exited",(for the process closure) and "myprocess_Disposed"(for the thread closure) events.
The problem comes when I terminate the outside application manually; these events do not appear to fire when the application is closed by the user, rather than by code.I thought, since the application closes with an error code when it is terminated in such a way, that it raises the "myprocess_ErrorDataRecieved" event. But this doesn't appear to happen either. Here is some of the code from that class:
'Some of the decleratoins
Event ProcessStarted(ByVal Process As Process)
Event ThreadStarted(ByVal Thread As System.Threading.Thread)

I need a simple system that allows one process to check if another process is running (I think I can do that fine using Process.getProcessByName or similar) and then trigger an event in that process assuming it is.When I say trigger an event I do not mean that literally. I simply need to trigger a sub in the first process from the second.I know that IPC like this would normally be done with pipes or remoting or something like that but I have no experience with these and am looking for a quick solution, so unless these can be used relatively easily to solve this I am looking for an alternative.
View 2 RepliesI have tried to make a program not able to be forced to close by naming it the same as a system process. However, this only works on XP, not on Vista. I don't actually mind if the program is closed but I would like something to happen when it is, thus being able to end the process is not good.Is there any event that can contain code to be run when the process is stopped? I'm guessing not but it's worth asking. If not, is there any other way to stop this? Maybe have 2 programs continually watching for each other or something?

I have a program which has 2 forms. I execute form1 first because it reads files and then writes to a file. Then I execute second form (form2) that will read the file created by form1.
How could I make form1 start form2 once it finishes reading file and writing to a file?
The following loop starts in x then loops thru y 20 times then goes back and finishes x. how do I get it to loop thru x then complete loop y then loop x once more then loop y completely again 20 times then back to x and another 20 ys. there should be 200 loops today.

In an application I have, when a user types in a textbox, the data in a listview is refreshed to reflect what the user is typing.As it stands, it does a refresh after each key is entered.Is there any way to smartly wait until the user has finished typing before initiating a data refresh?
View 2 RepliesI am working on an excel add-in. Currently I have a couple of forms that grabs info from excel, processes and pastes data back into excel.My problem occurs after my form closes (this leaves excel and one other MDI form still open). I need my excel sheet to come to the front for users to view and edit. My MDI form just stays on top even though I just edited the excel doc. I have tried everything I can think of using:

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'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.
In Windows 7 if I launch Task Manager and select a process (eg:Notepad.exe) I can right click on this and select "Create Dump File".
This creates a dump of the file to my hard drive.I would like to do this programmatically.
what is the method to tell when a user starts or stops a process? My company makes a software package that allows a tie in from vb. I want to make a package to allow me to start and stop the software remotely and to monitor when the software is running or not.Ideally there would be some sort of event in windows when the user starts or stops the software. I imagine there is some sort of way to do this with a timer, but I am sure that windows will have some sort of event process when the program starts. I have googled this and looked through the xtremevbtalk forums for this but I am not quite sure as to what keywords to use.

Finding documentation on XML is really difficult, because there is so much yet all of the examples seem to do it a different way.

Do not want to use windows message to process for paste/right click paste event.
IN VB.NET (not c#)I want to create an event than can be canceled by the listener. Just like you can cancel the closing event of a winforms form in which case the form won't close.I have already implemented a derived class from EventArgs that has a settable Cancel property as follows:
Public Class AnnounceNavigateEventArgs
Inherits EventArgs
Private _cancel As Boolean = False
[Code]...
The listener I have setup is setting the property to Cancel=True. I thought ByRef meant that both _cancel and cancel would point to the same location on the stack and that setting _cancel=true would therefore make the cancel = true. But this is not the behavior I am getting. _cancel becomes true in the setter but I guess the argument to the constructor remains false.
create an Enter event.
Private Sub txtField_KeyPress(ByVal Index As Integer, ByVal KeyAscii As Integer)
Dim vbkeyreturn As ValidationConstraints
If KeyAscii = vbKeyReturn Then
MsgBox("hello")
End If
I am using the folowing logic to create an event that can be canceled...
Code:
Public Class ParentClass
Private WithEvents MySubClass As New SubClass
Public Sub DoSomething()
[Code].....
It is my opinion that if you needed multiple things to happen either you would implement some coordination between your event handlers as to who chould cancel when, or have one handler that calls the multiple methods and decides the cancel in one place?
have just declare a button and it appeared on the form.but i want to create event for it.example event click:this is code create button
