Launch A Java Executable (let's Call It MyApp.jar) From .Net Using System.Diagnostics.Process.Start?
Apr 20, 2009
I want to launch a java executable (let's call it MyApp.jar) from .Net using System.Diagnostics.Process.Start. What's the syntax in VB.Net? The command line syntax is this (if I recall it correctly - because i tried it a few days ago and it worked).
java.exe -jar MyApp.jar pathToSourceFile pathToDestFile
How do I run this command in VB.Net, using System.Diagnostics.Process.Start, assuming I have the following three string variables in VB.Net
pathToJavaExe
pathToSourceFile
pathToDestFile

I'm having a problem. I have researched this for over a week and have not found what I need. I find a lot of great suggestions but none of them work for me.My code and program works 100% if you put a valid program, process or file name in the box but if you don't, it crashes. Also if the program is not registered or in a known path it will crash.
I've tried My.Computer.FileSystem.FileExists(txtProcessName.Text) and System.IO.File.Exists(txtProcessName.Text)
But every variation I try thinks that none of the files exist.I don't want to hard code any of the paths or file names because I want this to be dynamic. I also want it to be a one file program. I know eventually I will need to get into multiple files but I like basing all my programs on a file that can be copied and pasted to any computer and ran without problems.
NOTE: This is a multi-function program. Not only does it start programs but it also terminates them, looks the process up on the web to see if it's spyware, adware or a valid program and it also is a Task manager.

I'm using System.Diagnostics.Process.Start to open a file using a string stored in a SQL datatable. It works absolutely fine as long as there is an application on the local machine associated with the file type. If there isn't an association, what happens is the "Save as" dialog box pops up. What I'd like to happen is to just bring up a message box or some other prompt that tells the user what the problem is, and to contact the helpdesk. Some users will be confused if they see a "Save as" dialog box, I think.

I have a vb.net 2008 application that is supposed to run at startup. After meeting certain conditions, the PC is supposed to restart. Below is the code that is failing:
System.Diagnostics.Process.Start("shutdown", "-r -t 00 -f", myUsername, myPassword, myDomain)
myUsername and myDomain are both strings while myPassword is a SecureString. The application works properly when execute manually, but give the following error when executed from startup (either by placing in the startup folder or by adding to the registry):
The directory name is invalid
Also, the program executes properly when the last 3 arguments are left out and the user has the necessary rights.
How do I force a restart using an specific, alternate user credentials on startup?

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 system.diagnostics.process to launch a web page in the browser: system.diagnostics.process.start("http://........").
It works well. My question is how to get a return value? What if the browser has failed to launch the address or I'm not connected to internet? Can I catch it by any return value?

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

I am fairly new to VB.NET (but have vast professional experience with several other languages) and am completely new to these forums (so please don't burn me if I posted in the wrong place). I have run into a rather odd quirk with System.Diagnostics.Process.GetProcesses. I have a sample application (source posted below) that checks all running processes every second for changes (created and destroyed) and tells the user what has changed, if anything, in the last second. The sample runs for anywhere between 29-72 seconds before issuing an array out of bounds error. It appears that the Windows system processes, SearchProtocolHost.exe and SearchFilterHost.exe explicitly, disappear from the list causing my application to throw the aforementioned exception. Specifically the exception I am receiving is as follows:
Unhandled Exception: System.ArgumentOutOfRangeException: Specified argument was out of the range of valid values.I have noted in comments where the exception is thrown in the code below. If any of you would be willing to try this sample on your PC's or could suggest potential issues with my sample that could cause this problem
My sample code:
Imports System
Imports System.Diagnostics

I am tring to build network toolkit for my very computer illiterate techs. What I am trying to accomplish is to embed a command prompt of sorts in a form. I have been sucessful to a point. Here are my main two problems.
1: I cannot read line by line as the output of the process is generated. Rrather I have to wait untill its complete, this is ok for "IPConfig and Maybe "Ping". But for longer diag tests this would take too long and it would look like the app has crashed. So I need to figure out how to redirect the output of the process to my text control.
2: I would like to have the ability to redirect keyboard input to the process. For telnet as an example. I would capture all keyboard commands while my text control has focus and send them to the process and with the problem solved I should be able to establish 2-way IO with the process. Is there a way to do this or am I barking up the wrong tree.

Trying to integrate the google closure compiler in a batch job of mine and having difficulty getting it to work.Using command prompt I can enter the following command and get my scripts compiled. (The command is a self explanatory example)
java -jar "compiler.jar" --js_output_file="myOutput.min.js" --js="input1.js" --js="input2.js"
I have tried to replicate this using the System.Diagnostics.Process object but thus far have failed.I have tried
Dim command As String = BuildCommand(CompilationScripts, Me._Output)
Dim process As New Process
process.Start("compiler.jar", command)
And I have tried
Dim command As String = BuildCommand(CompilationScripts, Me._Output)
Dim process As New Process
process.StartInfo.Arguments = command

I have a read only file and I am using System.Diagnostics.Process to open the file.If a user tries to save the file the "Save As" dialog box opens because the file is read only. The "Save As" dialog box brings them to the directory from where the file was opened from.

I have an windows application (created using visual studio 2005) and it also is using an autocad .api. The user runs Autocad and the user enters various commands that will open forms. One of these forms, contains Windows.Forms.LinkLabels with paths to the autocad drawing files they've attatched (.dwg). When they click on the link, I need the file to open in the existing Autocad they already have open; however, the problem is that it's opening a new instance of Autocad and placing the file into it. How can I make it so it opens in the existing Autocad program already open? [Code]

I am building an internal web page which retrieves binary data from a SQL database, converts the binary to an image file, then opens the file on the clients PC.In debug mode, this works fine, because the program downloads the file successfully into a temporary directory, converts it to the image then uses System.Diagnostics.Process.Start() to launch the image file in the associated image viewing program.However, as soon as I upload it to the server, two undesired things happen:
a. The file gets saved on the servers temporary directory, instead of the client temporary directory (I kind of expected this to happen, so this wasnt much of a suprise)
b. System.Diagnostics.Process.Start() does not launch the file successfully. Nothing actually happens when it gets to this part of code, however I suspect that it is trying to launch the process on the server end, instead of the client end.
how I can get System.Diagnostics.Process.Start() to launch on the client end OR how I could get the image to just appear in the clients web browser instead?

I have an issue in my project I am programming in both Matlab (Matlab2011a) and Visual Basic (VS2008).I've created a .exe file from my matlab code. It works well when I click on it with my mouse.But I need to run it within Visual Basic. I know it's possible to call .exe files with Shell() or Process.Start(), and it works well for files such as firefox.exe or notepad.exe. However, it doesn't work when I call my own .exe file ...It's weird because when I look to the Task Manager while trying to call it (within VB), I can see the process starting and ending, but its output doesn't appear.

I'm using Process.Start method to launch another application from my application. Until today, there was no problem. But I have tested my application in a different OS, Windows XP (SP3), and my application didn't work right on that. I'm also using arguments to run that application. I guess for some reason my application couldn't send arguments to other application correctly under Windows XP. Maybe it is related to my code. But you should know, it works great on Windows 7.

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'm doing, well trying anyway, a calculator that is well fitted for "us analogue/HAM Radio enthusiasts", with basic AC and DC formulas, and a search-engine.... And it's this search-engine that gives me a darn head-ace!I placed a TextBox object at the bottom of the form, and first I just had a Button and a Label, saying "try google?". And a LinkLabel and a Process.Start method.
Dim search As String
LinkLabel.LinkVisited = false
search = TextBoxSearch.Text
System.Diagnostic.Process.Start("IExplorer.exe", "http:google.com/", search)
And I then got in my head that it would be cool if I could add a second TextBox object and the user could simply type in the search-term and when the Process.Starter called i.e. IE6/7/8... would open google, and displayed the result of the search on google, in the browser..But how ever I try, I get only a browser to start with google's url or exception error, though I have a try/catch method ...What I want to achieve is a "google toolbar" on my calculator, I haven't yet learned how to use VB script and it's probably that which fault me..

I have a vb2008 .net2 app that needs to launch an executable with certain cmd arguments. Lets say for example I have 5 variables.
variable1 = true
variable2 = wirelessssid
variable3 = password
variable4 = nothing
variable 5 = username
Each variable represents a cmd args that I need to launch the executable from my app with.

I am using a System.Diagnostics.Process to execute dirquota.exe. I catch an exception at .Start() which is "The system cannot find the file specified".
I am now doing:
foreach (var fi in new DirectoryInfo(@"C:WindowsSystem32").GetFiles())
{
Console.WriteLine(fi.Name);
}
This outputs pretty much every file in that directory apart from dirquota.exe.

If I have two apps which I have written with vb 2008 for windows 6 device lets say app1 and app2. App1 is running but then needs to start app2 - then app2 needs to shut down app1 and do some updating of app1 then app2 needs to restart app1 and app2 then needs to be shutdown. I am aware of the systemdiagnostics.process classes. One thing I don't understand is how to shutdown app1 from app2 how would get that processid of app1 due to the fact that you havn't access to getproccessbyname methods.

It's probably the most basic of things, but all I can find is how to launch a program, and not with the interactions I desire. Any tips as to the terms to use to search for answers, or links to topics regarding questions similar to mine, would be very appreciated. I have a wealth of info to read through, but I could use your knowledge to save myself time.Here is what I am trying to do:
Use a Button (A) to Launch a Prompt where User Selects Directory Path to an executable Program. The Selection is to be Persistent after the initial selection (saved in a settings file i assume?), and the Selected Path (or just "programname.exe") is to be Displayed in a Text Field (B). Launch Selected and Indicated Program via a Launch Button (C)

When I use System.Diagnostics.PerformanceCounterCategory.GetInstanceNames call, I always get 0 instances returned the first time. If I actually query for a counter value first (using perfmon) and then call GetInstanceNames, it works fine. Can someone provide some insight? Do I need to get a counter value first (in code) and then use the GetInstanceNames?
