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.
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.

When i try to run a msi using System.Process.Start("test.msi") in a vb app i get the following error. The installation package could not be opened. Contact application vendor. Msi file works fine when double clicked, tried System.Process.Start with text files and exe files and they work fine, problem only with msi files. Running vista. Also tried xp but no luck.
View 2 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")

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 9 RepliesI have a service made from VB2008. It works fine on my station and on several others. However, on some stations, I get an "Error 1067: The process terminated unexpectedly". The service includes a log writing procedure in the OnStart event but the service crashes before even getting there. This is really weird because, as I say, the service runs fine on several stations. At the moment, the service is a full-trust app, is set to logon at Local System level and has the following manifest settings:

How to get full path of current directory of process from where process starts Like if i use my software to start somefile then I want my software to know where she started it from ( files path) What I mean is the file I opend using my softwares location.
View 2 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 :

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 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've got a painfully simple table that is giving me a "Specified cast is not valid" error when I try to delete one or more rows.

I am making a simple app to start external apps not built by me, already installed on my PC.
This:
Dim GenericExePath As String = Path.Combine(ProgramFiles, "Generic DirectoryGeneric.exe")
Works fine for most cases, but I have one exe that needs to be launched from within it's root directory.
Example: I have to go directly to the root folder to launch it.I have been able to physically create a shortcut in the root directory and launch that shortcut itself with my app and it works fine.But, how would I do this programatically without having to create that shortcut...

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")

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?
