Exiting A .net Windows Form App From Command Line
Jan 25, 2011
I have written a windows application, that can take in some command line arguments and can be ran from the command line as a scheduled task. It all works fine, but i am trying to give the user some feedback on the console if they launch it from thee.I have used the info described here, and have got some output on the command line, but when the application finishes it does not drop back to the command prompt unless you hit enter it just sits there waiting.

I am trying to send a command to the external command line (cmd.exe) from the Windows form application that I'm writing in VB.NET (using VS2008).
I can only access the external program thru the command line (its not my program) and I must do so from a form app.
I am trying to use the following code. I am able to call a cmd.exe window, but I can't pass the command line my command.
Using mp As New Process
With mp.StartInfo
.FileName = "cmd.exe"
[Code].....

I am working on an application and I want the user to be able to enter commands into a textbox, and when they press enter, the command is printed in a rich text box, executed, and the output is printed. For instance: the user types move{file1}, {location} into the text box and this happens:
>command: move{file1}, {location}
>$ moving file1 to location
>job completed
How would I write lines to the rtb and execute commands when the enter key is pressed?
This works, partly.
Private Sub TextBox1_KeyPress(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles command.KeyPress
If e.KeyChar = Microsoft.VisualBasic.ChrW(Keys.Return) Then
RichTextBox2.Text = Environment.NewLine + command.Text
End If
End Sub
it erases everything in the textbox before adding the line... I would also like to be able to make a database of commands, maybe a .dll or something, so that when the user types in something, it checks that database to see if the command exists, if it does it executes, if not, error.

Hey Overflow, I have an application which serves as a user interface for a spartan/command line program.
I have the program running on a separate process, and my application monitors it to see if it is responding and how mush CPU it is utilising.
Now I have a list of files in my program (listbox) which are to be sent to the application, which happens fine. But I want to be able to read text from the com-line so as to determine when the first file has been processed.
Com-line says one of "selecting settings", "unsupported format" and "cannot be fixed". What I want to be able to do is when it says one of these three things, remove item(0) in listbox1.
I thought of programming an event which handles com_exe.print or something or other, if possible.

I have a simple question that I can not figure out.I have a service (service.exe) that is running as SYSTEM.I want to be able to send this service command line arguments. How would I do this? I am not able to just service.exe /arg because the service is running as SYSTEM and I am logged in as an admin. Is there way?

I have beginner skills using VB (am using the Express edition to learn). I would like to know how to set up a conditional statement in a Windows Form (WF) app that would check if a specific command line has been passed by another separate app that launchesthe Windows Form app using command lines, and if not passed, then the Windows Form app would shut down (exit, close).So far, I can use:
For Each s As String In My.Application.CommandLineArgs
If s <> "xyz" Then
Me.Close()

We have an application that works well on XP/Pro, Vista, Windows 7, Windows 2003 Server, Windows 2008 Server (32 bit) but is problematic on Windows 2008 Server (64 bit). The application uses an unsigned activeX control which may or may not be related to the problem. To install we need to add the program name and regsvr32 as DEP exceptions. Once that is done the application installs correctly and operates normally except when the application closes.
If a user clicks the 'exit' button our code basically says 'unload me' (where me = the main form of the application) and there is no code in the form_unload section of the program.
Everything works well on every Windows platform except Win 2008 64 bit where we get
APPCRASH
Application Name: PDFPrint.exe
Application Version: 10.10.0.18
Application Timestamp: 4d238253
[Code].....
After we continue to close the program we see a message box with run time error 216 at 00002B24 message.

First let me say that I am not sure whether or not this should go in this section or the API section, and if it needs to be moved I apologize. My issue is fairly straight forward, but for some reason I cannot get it to work.
I am trying to send a command to a command line and then submit the command. I have been trying without success to get this to work in v2008 Express and v2010 Express, Here is the code I am trying to us:
Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" ( _

I was playing a game recently and saw that they could use args in the shortcut, and I decided to try to impliment this into my application...so far, I got: (runs this sub on load)
Sub startup_args()
If Environment.GetCommandLineArgs.Contains("+game") Then
Dim path As Array = Environment.GetCommandLineArgs
[code]....
just to see what it returns, but the application crashes. I also tried path.tostring(), but that didn't work. When I did:
If Evnironment.GetCommandLineArgs.Contains("+game") Then
Dim path as string = Environment.GetCommandLineArgs.tostring
MsgBox(path)
[code]....
but that returned the value "SString.Array[]"...

I am using the following code to run defrag and to analyze if the C: drive requires defragmentation:
Dim analyze As Process = System.Diagnostics.Process.Start("C:WindowsSystem32defrag.exe", "C: /a /h /u /v")
This process runs through analyzing, runs it in normal mode & prints the progress to the command window.
My problem is that as soon as the process is complete the command window closes. I need it to stay open so that I can read the results.

I am using a CheckedListBox that is populated with Filenames (full path, i.e. C:TestTest.jpg)When I have the files that I want in the CheckedListBox I wish to click a Start Button which will process the list one at a time using an exe program that runs on the Command Line. There are arguments that need to pass to the command line as well as the file location in order for the program to process.I currently have it working but the issue is the loop finishes quickly and it is left up to the CMD.exe to finish the process. What I would like is for the LOOP to wait until each file completes processing before passing the command for the next file in the CheckedListBox.There some reasons I wish for it to work this way.
1) I would like to have a button that can Pause/Restart the Loop.
2) I would like to have a button that can Stop the Loop so the whole process can end.
3) I would like to have the Loop remove each file one by one from the CheckedListBox after it has been processed.
4) I would like to display a Message once all the files have been processed.
5) And if it were possible I would like to report the status either by text or a progress bar showing where it is at in the process.
6) And the ability to add some error handling if possible.
Since the Loop finishes so quickly as it just passes the command to the command line using the & as a seperator it is the command line that is handling the rest of the process. Because of this there is not control over it in the GUI.The code I am using allows the Command Line text to display in the Form so it won't open up a seperate window to run CMD.exe. This is the desired affect as I would like everything to appear to run from within the Form itself.

I am struggling to pass a parameter to a VB.NET application via a Windows scheduled task. It works perfectly in Visual Studio (passing a command line arguement via project properties).If I am calling a VB6 application, then I will supply the following parameters and it works:
Run: c:progra~1TestTest.exe TestParameter Start In: c:progra~1Test However, if I supply the same parameters in VB.NET, the program throws an exception when it tries to create an instance of a class in the Form.Load: System.NullReferenceException cannot create instance of object.
I have also tried the following:Run: c:program filesTestTest.exe TestParameter Start In: "c:program filesTest" This time the status of the scheduled task changes to "cannot start".What is the correct way to specify command line parameters in a scheduled task for a VB.NET program?UPDATE I found the solution on this web page:[URL}.. I am still confused as to why the program would not create an instance of an object when I used the 8 bit paths (i.e. progra~1)

I want to run the following command line program from VB.NET: rotor95.exe -d -k "password" -i "C:FileLocation" -o "C:FileLocation" The reason for this is that I don't want my users to have to drop out to a command line prompt in order to run a tiny program for 3 seconds. Typing in a 50 - 75 character file path twice isn't any fun either.
I tried using tooltask as discussed in the MSDN2 help but it appears to work with switches (/d etc.) but not parameters (-k "password"). I couldn't get the thing to work. See the following for the tooltask example:[URL]..light now I'm just using Shell("rotor95.exe -d -k "password" -i "C:FileLocation" -o "C:FileLocation") which works just fine but I'd like to use the .NET 2.0 super-whammy version of handling this problem if there is a better way to do it.

how to use basic FTP functions straight from the command line tool. and I started using Visual Studio to create "macros" for the command line tool (i.e. writing down specific functions to perform, write them to a txt file and then run Shell() to execute.)But what I want to know is if I can open a command prompt window and then interact with it. Say for example I'm writing an FTP class/object, I'd want to be able to keep a window up for my program to send commands to (And wishfully read data back from it.)Because it seems to me that whenever I use the Shell() command it just opens a prompt window and then closes it after my line of code has been executed. Is there way to interact with a command line window from Visual Studio? And maybe even scrape data from the terminal like with terminal emulator scripts?

I have a console application which reads .txt files. I want to be able to drag a txt file over my app and it would automatically open my app and show the text files contents. I think I have to use command line arguments like this:
Sub Main(ByVal cmdArgs() As String)
End Sub
Sub ReadFile(FilePath as String)
End Sub
But how can I pass the text files path to my ReadFile sub?

OK! I've written my application in all it's GUI glory. I now just want to be able to run it from dos/a command line/batch, with no GUI appearing? So it just runs (& does its batch process).
How can I detect if my application has been initiated from command line/dos?
How do I then not open up the application and show its GUI etc?
