Forms :: Command Line, Hide Console And Get Feedback?
Jan 17, 2010
I am working in VB. I have a fairly long and detailed explanation that I'll avoid posting but what I'm looking to find is quite simple. I'm looking for information how the command line executable LAME.EXE (the Mp3 encoder) returns information to the host program/form.
I am a VB novice and a novice to programming in general and am looking to learn more about as much as I can on the whole but basically I have a Windows form that gathers all the necessary information as a front-end:
The input .wav file path
The output .mp3 file destination
The encode settings (bitrate, frequency, etc)This information is pooled in to a string like this: lame.exe -v -b 112 input.wav output.mp3 or any variant on the settings selected in the GUI which is then in turn used to execute LAME.EXE with the set of parameters in a command line console...That's all well and good and it is quite functional but what I'm looking to do is to 'hide' the console in itself and have the encoder feed back its progress, say as a percentage inside the GUI.
The problem is that it doesn't appear that LAME in itself has this kind of functionality explicitly built in. I know it's possible however, as every single front end in the world has this functionality.I have tried a few ways of doing this with avoiding the issue of not being able to find the functionality within the codec. Perhaps I'm looking in the wrong place entirely or I'm not thinking correctly 'outside the box' as it were.
what I'm looking for is to use a command like this within the script itself: lame(v,b,112,"C:input.wav","c:output.mp3") or even pass the parameters obtained from the GUI a string formatted dynamically on the fly itself.I expect of course that this kind of functionality won't be available anywhere at all, what I'm really looking for as a workaround that reports the actions/progress/console output of the executable back in to the VB program somehow.

I would like to create a console program in VB.net that would allow parameters. What i would like to do is in the code below add parameters so the webpart page can be created from the Run menu. e.g. C:.......MyProgram.exe "Design" --This would then create the Design webpart page.
I tried looking at the internet but was not very successfull.
Module Main
Public Sub Main(ByVal args As String())
Dim prj As String

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 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?

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.

I am writing an application in which a user is doing a file conversion. I have a set of tools that can perform the conversion on the fly via command line, but I'm not entirely sure of how to go about passing the parameters I need to the command line and running them. Can someone point me to the right direction?Would I just create a System.Diagnostics.Process and use that? If so how do I do the line by line command? For instance if I need to issue a cd command to change the directory and then execute a command after that how would I do that?

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()

I was thinking of adding a simple bandwidth monitor to a console application and I was wondering if it would be possible to keep a line in the console window visible at all times. I could set something up manually to pass new console output into a method that would get the contents of the console, clear the console, add the bandwidth data on the first row, then rewrite each line of previous information back to the console, etc.. but that seems like a really hacky way to go about it, and I'd be limited to the amount of rows visible at once in the console window (no scrolling).

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"

so so far I've gotten my console application to minimize itself, but I want it to be totally hidden: so I want to disable it from showing in the taskbar too. With a Windows form this was easy, but I'm not so sure about console apps.

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 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 square...no window, no frame, just the inky blackness of frustration.
