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?

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()

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" ( _
ByVal lpClassName As String, _
ByVal lpWindowName As String _

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 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"

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.

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?

I have a forms app that contains a few forms. My task is to make it run invisibly when called from the command line with arguments.I have defined a Sub Main in a module and made it the startup item. I have an if/then/else that looks at args.length and if it equals 0 then I load the form and run the app normally. But how do I handle things when args are passed? I still need access to all the functions defined in my main form. Can I load the form invisibly and still "use" it?

When you open up a .txt file, the command line opens up notepad.exe with the argument %1. which opens the text file. i dont know about the function but i understand a little bit about it.
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.

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]....

However, I've just inherited a problem and was wondering if anyone knows if I can solve it with a command line application written in .NET. Basically, we have a SAP transaction which has been written which imports data from a csv file.At the moment, it will be a manual process requiring someone to log in and run the transaction. Does anyone know if it's possible to action this from a command line app which we could then set up as a scheduled task?

I've been trying without success to get this working; I am trying to use 7zr.exe (7-zip) to archive things and the like in visual basic. There's a catch: I don't want the cmd window to show and most importantly. I keep getting errors.
To that effect, could someone please translate this to VB viable code (preferably using shell):
"(7zip path)" "e (sourcepath)" "-p(Password)" "-o(Directory)" -Y
I'd keep at it, but it's getting really frustrating.

First off, i'm still rather new to Vb.Net but am enjoying learning it, I have this code to run a shutdown:
'// Thread Process for Shutdown Process
Private Sub BackgroundProcess() If System.IO.File.Exists(dbfile) = True Then
Try Dim shutdownCount As Integer
[Code]...
It runs ok. Currently it looks through a number of computer names and shuts them down. But sometimes it can take up to a minute for anything to be returned by command line if for example a computer is switched off. So what i'm trying to do is get it so it doesn't continue the loop UNTIL there has been something returned by command line. Some maybe to do with While p.HasExited or something? Is this possible?

I'm trying to run a command line argument through VB.NET using the Shell() command.I'm trying to use this piece of code:
FOR /R %I in (*.pdf) DO @pdf2swf.exe "%~fI" -o "%~dpI%~nI.swf" -f -T 9
-t -G
Using this:
Shell("FOR /R %I in (*.pdf) DO @pdf2swf.exe "%~fI" -o "%~dpI%~nI.swf" -f -T 9
-t -G ")
However, the interpreter is giving me this error:
Character is not valid. (BC30037)
For the %~ part.I also tried created a string and passing the argument to the Shell() command by using Shell(StringName) but I still get the same error in the string.

In a Windows Form project (using VB Express 10), is there a way to use a second command line arg (first one is in a module1 for start-up that checks another command line, and if correct, runs app)? This second command line would be used to close the open app (including all forms)? (I already have set up a Module1 to recieve a command line to run the app. This would be a second command to close the running app.)
I am opening the WF app using another app (created in a different software) that can pass command lines. So, if in that other app, I send "close" as a command line arg, how do I set up the WF app to receive this specific "close" command and perform Application.Exit()?
As a beginner using VB, not sure where it would go, how to declare, etc.

So I'm tasked with writing a command line app that tells you the file size of a given directory. I'm basically going to replicate what the command dir /s <dir> does, but output the result to a text file to make it available for parsing later on.
Using VB.NET, I'm at a place where I need to get the size of a directory, but it seems there's no such ready-made property in the DirectoryInfo class. How do I get the size of a directory?
EDIT: If there's a built-in command or switch that can be typed into command line to automatically output the results of an operation to a .txt file then that would make this infinitely easier.

I'm trying to do a little project with an embedded board and XP embedded OS to control a little machine. The board will have no monitor, so I need a little routine that when a key is pressed on the keyboard, it invokes a proper Windows shutdown.I want to have the letter "Z" trigger the action. I've found that the sequence I want to run is ultimately this
Code:
SHUTDOWN -s -t 01
I'll put the routine in the start folder so that it's always in the background waiting for "Z", but is there anything else that has to be done since the machine controller software will be the "active" program?
