I know how to launch a file or executable in VB .NET 2005. The file will launch and execution in the code continues immediately.
Process.Start("MyProg.exe")
But what if I need to start the program, wait until it finishes executing, read the exit code that it sends back, and take some action based upon the action code? How do I do that?
I'd like to have a function in my program that waits for a process to start, and once it does, it executes the code. Id like to have a form of 'buttonless messages box' or 'splash screen' waiting saying "waiting for process to start..." and once the process starts, a message box will pop up saying "Process has started!".
I was thinking of having a timer with a low delay constantly looping to see if the process exists, but that would be a little rough on the processor, no? Also, how would I accomplish the 'buttonless messagebox' that automatically closes once the process is found?
I am running macros from a button click in my application. I want the macros to run sucessfully before it start another process. I want the StartMacrosI to start and complete first before it starts DeleteFilesI. I need to wait for it to complete before I do the next function/sub.
Below is my code.
Private Sub Button2_Click(sender As System.Object, e As System.EventArgs) Handles Button2.Click
StartMacrosI()
DeleteFilesI()
End Sub

I am using Process.Start in my application, which is working great.My only problem is, the program it "starts", is an installer, which takes about 5 minutes to install. I woud really like to hide all my forms and only show one that says "please wait", but i cant seem to get it to stay there till the process has finished.

View 3 RepliesI'm using Process.Start to start an external command line application and using the StartInfo.Arguments method to send parameters to the application. I imagine I'll need to use a loop... but I can't figure out exactly how yet.I need to send anywhere from 1 - an infinite number of files names to this application. Each file has to be sent one after the other. So once the first one is done, I need to loop back around and past the second one.I can probably use the Directory.GetFiles method to get all of the files, but I don't know how to assign them.

I have an application (application #1) running with Administrator privileges on Windows 7.
I want application # 1 to start another application (application #2) without Administrator privileges so application #2 is running as a standard user.
Is there a way to do this? I have been using Process.Start.
Here's what I currently have:

I've commented out various things to limit it to specifically this command (example, I can swap mklink out with notepad and it works fine). The command runs fine from a DOS window, but can't be found when I use it this way. I also tried using the SHELL command just to test and I get the same results. No idea why it can't be found, as like I said it executes from the command prompt just fine.
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.
Trying to create a button that when clicked will check to see if a certain process image is running and if that process is running give the process focus. If the process is not running then start the application.

View 6 RepliesHow would I go about starting a new process without it being the child of the calling process.
Example:
Main Program (Caller.exe)
process.start("file.exe")
i use System.Diagnostics.Process.Start to run a process
example :
Dim p As New System.Diagnostics.Process
p = System.Diagnostics.Process.Start("D:ProjectApplication.exe")
it works perfectly during run time. but after i deploy to server.... this code did nothing, it did not call out this process
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.
I am working on a game launcher, and I need to display a "Splash screen" until the main game has started. For this, I need to know whether or not the Process has a Main window that is fully loaded and displayed.Now I noticed the main window handle is 0 when there is none, so I tried to use that:[code]But the handle never becomes nonzero. I tried to use the title but to no avail.I do not want to go into "Thread.wait()" since then the splash would remain even if the game is already launched.
View 4 RepliesI am writing an application that in the end needs to execute another executable at some point, the problem is that the executable has dependencies in the directory it runs in that are required to operate. When I use the Process.Start to run the executable it errors out because it's looking for the dependencies in my applications directory.
I tried the startInfo.WorkingDirectory option but that didn't seem to do it either (not sure if I did it right) - here is how I used that:
Process.Start("my.exe").StartInfo.WorkingDirectory = "C:Test"For the life of me I cannot find how to set the "Start In" directory. I looked everywhere, so unless it's under a different name, I'm at a loss.
I am trying to create an app that will perform actions on specific times (much like the Windows Task Scheduler). I am currently using Process.Start() to lunch the file (or exe) required by the task. I am initiating a process by calling a file (an .mp3) and the process starts WMP (since it is the default application), so far so good. Now I wan't to kill that process. I know that it is normal behavior for the Process.Start(string, string) to return nothing (null in C#) in this case. So I am asking how can i close WMP when I called it through Process.Start(string, string)??
[Code]...
Is it possible to use system.diagnostics.process.start("Process.exe")But the process would not be seen by the user? For example, I want to play an audio in the background using windows media player, the audio will play but wmp won't be visible. Is it possible?

View 9 RepliesI'm trying to execute a 3rd party application, called from a .cmd batch file, called from a self-hosted WCF service. Like this:
WCF --> .cmd --> 3rd party app
For whatever reason, using the Shell command doesn't work fully. It will call the .cmd file, but the 3rd party app won't kick off (I know the .cmd is firing because I have before/after ECHO statements populating a log file). If I double-click the .cmd file from explorer, the 3rd party app will start just fine. So, I figured, maybe try something besides the Shell command from my WCF service.
So I tried the following code, but it won't kick off the .cmd file at all (echo statements not firing). What am I missing here?
Dim psi As New ProcessStartInfo("cmd.exe", "/C " & System.Configuration.ConfigurationManager.AppSettings("ExStream_CMD_File_Path"))
Dim proc As New Process()
proc.StartInfo = psi
proc.Start()
proc.WaitForExit()
The path in the app.config file is valid (just double-checked). Is there anything wrong with the above code?
Is there any way I can install a global hook or something else on the start of external process. WH_CBT hook, as it appears can only intercept events for processes that have windows, but what if I want to intercept the start/stop of a windowless application or a windows service? Is there any way to do it using .NET?Generally, I want my application to receive a notification of some process being launched knowing only an executable name.Presently I simply use a timer to iterate through running processes, but I wonder if there a better way to do it?
