Process.start() Freezes Main Program Until Process Finishes?
Feb 21, 2011
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.
im working on a little project what executes a bat file on a button click using this command:Interaction.Shell("read.bat", AppWinStyle.NormalFocus, True, -1)however when this is executed the program will become unresponsive while it is running... this may be simple but is there a way i can make my program be responsive and for it to execute in the background?
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..
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.
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.
Dim Password As String = "password" Dim SecureStringPassword As New System.Security.SecureString For Each c As Char In Password
I've created a small application that basically reads and writes to a single Excel.exe process. It's basically a timer that records the time I use on projects and then store it in an Excel sheet. This works great, however, I've noticed that if I open Excel manually, work on some sheets and whatnot, save and exit etcetc, the process my software use gets broken or something. The same thing that happens if I manually close the excel.exe process and my software doesn't "know".
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)??
i am trying to write a little program that checks for a process and kills is.here is the
Dim p As Process = Process.GetProcessesByName("Cheat Engine")(0) p.CloseMainWindow()[code]...
My problem is it�s woking ,yes if the programm ,,Cheat Engine" is running the process is getting killed.But if the program is not running my program crashes.
The program opens with the correct registry value, but the program itself does not run quite right. This program feeds into Intergraph and brings up the selected drawing, but there is a feature of intergraph that doesn't work. If I manually start ( double click ) pdsicon.exe the program works just fine. It only when I call the process that it doesn't work quite right.
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 am trying to launch a program using System.Diagnostics.Process.Start("C:Program FilesFrets on FireFretsOnFire.exe") but the program always fails - the program generates an error log - so its obviously trying to start - ive included the log text but i doubt it will be useful.
Traceback (most recent call last): File "FretsOnFire.py", line 45, in <module> File "GameEngine.pyo", line 23, in <module>
Yet it runs fine when double clicked? why i can launch it from explorer but not from my 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?
I'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'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.
I have 3 questions: How to get the process which the main window is active How to change the WindowState of that process main window How to resize the process main window[URl]..
I have a vb application(1) which is made to launch another software(2) with specified parameters, but i wanna keep my application opened as long as the 2nd one is opened too, and I also want to close the second one automatically if mine has been force closed by the user in windows taskmanager, on the desktop, or in any way.
So I need something which detects if windows is closing the program and kill the second application auto.
I would like to avoid the task manager block, because that isn't necessary for this i guess.
I have a VB.NET project (main.exe) and include an additional .exe application as internal resource. Now I do not want to run the extra .exe as a separate process but want to attach it to the process of main.exe so I have just 1 process overall and not 2.
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.
I have two applications. For performing certain functions, i run a second exe, via a process, and wait till it is complete (exited) to continue with my main application. I run through many repetitive functions on different files.Everything runs fine however, when i am doing a run and it is on the x loop number, the main application seems to halt the secondary process exe. I can only assume this is what is happening as, if i close/stop (not pause) my main application in VB, the second exe continues from where it was halted until it completes.
I have an MDI form as the app start object.I don't think is related, but in the Form closing event, I check for some condition, and if it's true, I ask for confirmation before closing:
Private Sub FormBackground_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing If (e.CloseReason = CloseReason.UserClosing) Then[code].....
So long, everything works fine in my development machine, which runs windows XP.However, when deploying the application in a windows 7 machine, the message box works correctly, showing itself whenever it should, but after the form is closed the application keeps running in the background. This happens whether the form closes directly or asks the user first.I have fixed it putting an End instruction in the FormBackground.FormClosed event, but it doesn't feel good.
I 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'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?
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?
