Forms :: Use Process.start Based On Settings File?
May 14, 2010
My first post! im quite new to programming but loving every minute of it.Basically i want to open another exe file from vb.net 2010. i can do it normally using
system.Diagnostics.Process.Start _ ("c:winamp.exe") if winamp for example is installed on another pc in another location i want to run it from my program but i want there to be sort of like a settings.txt file where you can edit the path to winamp and my program should first read the path set in the settings file and then open accordingly. how do i go about doing this?
btw it would be great if you could point me in the right direction for making a windows form where one can edit the settings file within my program without editing the settings file in notepad

I am using the Process.Start function to open a program based off a registry value. It works, sort of. Here is the snip of the
Imports System.Data.SqlClient
Imports System.Console
Imports System.Configuration
[Code]....
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'm working on a website where we'll be getting a lot of videos to be uploaded. To keep things simple and secure, I'm just writing VB.net windows app to suck all the files in a directory in, allow you to set some options, and start the encode by spawning a new FFMpeg process.

I am having a bit similar task, which I am not able to get thru. I'll explain..I have two apps A and B, B is kind of a reminder application which runs in the background..but that is not important here, thing is when App B is open, it has a button which takes user to App A, I am doing that using Process.Start("A.exe") all good so far. Problem is I need to make sure that if any other instance of App A is running then I need to jump to that instance. I am able to check for the instance running using Process.GetProcesses() but I am not able to set focus to that running instance.

I'm developing a vbnet/c#.NET based application that opens files with different applications(excel, word, etc).
The application is launched using Dim app As Process = Process.Start(ProcessProperties)
Now, when I have to terminate the process I use app.Kill() but I need to check if the document has been modified before killing it.
How can I handle that? And if it's possible, how can I launch the application native prompt for save?

I'm creating a sub that will run a batch file, and then delete it when it has finished.[code]...
This causes the program to immediately delete the batch file before it can run. How can I break it up so that it won't delete the batch file until after it has finished?

I have an application that that uses process.start. It works fine on my development machine...but not on an installed machine....at least not for a local file. The following illustrates my problem...the reference to the url works fine and every time. However, the reference to the local file may work the First time but on any following attempts will close the application with a WindowsApplication1 error. Since it can find the file occasionally it is not a file problem.

I want to launch a file from a VB program and capture the output of that file in a text document.Here's an example:Process.Start("systeminfo.exe > Data.dat")This doesn't work. I get an error that the file cannot be found. I've tried using Shell instead of Process.Start. I've also tried replacing systeminfo.exe with a variable and replacing the redirect portion with a variable.The ultimate goal is to get the text file e-mailed. So, if it were possible to output to the Clipboard, then paste that to a file or directly into an e-mail client that would also work.

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'm trying to open any file using Process.Start, but every time I try to open a file that isn't an executable the program crashes... This is the code I'm currently using:
vb.net
Private Sub ListView1_MouseDoubleClick(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles ListView1.MouseDoubleClick
For Each lvi As ListViewItem In ListView1.SelectedItems
Process.Start(path & "" & lvi.Text)
Next
End Sub
Path is a string that contains the selected folder path, and lvi is the text of the list view item (each item contains the icon and name of each file). It is working fine for .exe files, I was just wondering if it's JUST for .exe files...

Each year I have to create 1099s from a legacy system. So in the past I had Foxpro code that ran out of a directory near where the Foxpro dataware house was. In 2009 we moved to SQL so I have to convert the code to VB and SQL
But I need to still store the text files and the report and I wanted to save settings in this "working directory"
[Code]....
Does this seem like the propery way to do this?
Finding documentation on XML is really difficult, because there is so much yet all of the examples seem to do it a different way.

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.

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.

Im simply trying to load a file on my network. The file is a database file for access.. This code opens the file on my computer. However on the four computers tested 2 of them throw an error stating that the user canceled the operation. However the user didn't do anything. The error is thrown automatically. The other two are working perfectly fine.

I'm having different results when running openfiles.exe manually than when I run it with Process.start() Below is the portion of code making the call. I have read in several places that using the "runas" verb might make a difference since I am running on Win 7 x64, however I am still experiencing different results.

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.

Visual Basic 2010 - Net Framework 4.0 Client
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:
[Code]...
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.

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 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)??
