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.
View 1 RepliesI'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.
View 2 RepliesTrying 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

i use System.Diagnostics.Process.Start to run a process
example :

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

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.

I am trying to kill process using following code
Dim ItemProcess() As Process = Process.GetProcessesByName("vlc")
If Not ItemProcess Is Nothing Then
For Each SubProcess As Process In ItemProcess[code]....
Now I have created two sub in the first sub I started a process using process.start(preview.mp3)in the second sub I killed this process using the above code but instead of passing the mp3 file I am using the vlc.exe which is actually processing the fileFor this I have to manually check the task manager and get the process name.So my point is ,is there any way i can write a code that automatically the corresponding exe file that is using it.
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 have an windows application from where i start another EXE by using the system.diagnostics.process.
I do as follows:
private myExe as System.Diagnostics.Process
myExe = New System.Diagnostics.Process()
myExe.StartInfo.WorkingDirectory = "...my path ..."
myExe.StartInfo.FileName = "...my exe..."
myExe.Start()
What the title says. Are they the same? I've noticed that the first does have arguments and such, but are they going to give the same end result?
View 2 RepliesI 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 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?

This may be more of an OOP concept question, but here's what I'd like to do.I have an application that outputs debug information using System.Diagnostics.Trace.WriteLine so it can be viewed with DebugView.I'd like to override/extend (not sure of the proper terminology) this method to log the text to a file instead, or maybe in addition to the Trace output. This would allow me to write a new WriteLine method for my app, and I could leave all my other System.Diagnostics.Trace.WriteLine statements unchanged throughout the rest of the application.?

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.

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).
