Command Line Switches - Keeping Command Window Open?

Feb 24, 2010

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.

Command Line Argument: Check If Correct Command Line Or Exit App?

Jun 6, 2012

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

Send Command To Command Line From Windows Form Application?

Mar 11, 2010

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"

Command Line Program To End Before Moving Onto The Next Command In Loop?

Feb 4, 2011

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.

Open A Console / Command Window When Using VS 2008 Express

Jul 30, 2009

I have both the VB and C# versions of Visual Studio 2008 Express. When I run a console application in either version, instead of the console opening in an old DOS style command window like it does in VS 2005, it actually blacks out both monitors attached to my computer and treats the entire screen real estate as the console.Anyone know how to get the app to run in a small command-type window when I run it? It's like the console is running Full Screen. If I set a break point, switch from the IDE t the console and then hit Alt+Enter it switches to the small window that I want, but I still can't figure out how to make the app start with the console that way.I could post a screenshot but it would look like a big black window, no frame, just the inky blackness of frustration.

.NET - Pass Command On Command Line?

May 29, 2012

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)

How To Open Multiple Files Using "open With" Command Line Arguments

May 15, 2012

I have an application that can read certain types of files, and I have it working so that if you do "open with" from windows, it automatically starts the application and opens the selected file.

Unfortnately, I cannot get it to work for more than one file.

System.Environment.GetCommandLineArgs() contrains the following:
System.Environment.GetCommandLineArgs(0) = name and path to the .exe
System.Environment.GetCommandLineArgs(1) = name and path to the first file selected to be opened

System.Environment.GetCommandLineArgs().Length is 2 when the user tries to open 1 file, which makes sense since the first argument is the .exe itself and the 2nd is the path to the file, but it does not increase to 3 if the user tries to open 2 files... meaning that System.Environment.GetCommandLineArgs(2) is never populated Here is some sample code that shows the problem: It will recognize no files or 1 file being opened, but if you try to open multiple it will only show the first.

Run A Command Line EXE From .NET?

Mar 3, 2006

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.

Using FTP Over The Command Line?

Sep 19, 2010

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?

Insert Command Not Functional After Clear Command In Vb Report

Aug 21, 2011

User need to select their prefferable data to show in report. What i did is i have a clear command first to delete the temporary table. The temporary table is basically a table to stored user selection parameter data. After the clear command, i have
a insert command to insert user selection data into the temporary table. What happened now is when i run the program exe, first run of the report is work fined, but not the second and the following times of execution. It will return null or blank report. The weird thing is when i execute it from development environment, it seem like the report is able to pick up user selection parameter and run the report for the first times and the subsequent execution.

So what i wanted to do was create a .lxproj, and make it open up with my application. i have done this part so far with an installer that creates registry keys. but, what i would like to know is how to open the file. for a test i would like a message box to be displayed if the program is run by clicking the .lxproj. if its opened normally the messagebox doesnt display.

Run A Command Line Program?

Mar 25, 2011

I'm a bioinformaticist, I'm trying to teach myself how to develop programs that are easy for everyday users to automate programs used in biological research. I thought VB would be great for helping people be more familiar with bioinformatics. Unfortunately, I'm brand new to VB and am stuck with my first program.

All I want to do is have a window pop up where the user then selects a file from an OpenFileDialog box, and pass the filename to a bioinformatics program names msconvert. What I've been doing keeps giving me a message that seems to says, "Unhandled exception has occurreed in your application. . . . File not found."

However, as you can see in my code (below) I have a MsgBox that shows that the correct file HAS been selected, and I can get the whole thing to run from command line.[code]....
