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
Me.Close()

I know how to pass arguments between two dotnet applications! However I have hard time with this: I want to pass a command line argument. for example; test.exe is a console application (none dotnet) self terminating app. From cmd.exe if I type "test.exe -v" the cmd output text will display the test.exe version info. If I place the test.exe in the same path as my VB.net app.What I want to do is:

I am a beginner using Visual Studio Express 2010 to create a small console app to use as a utility accompanying another primary app that can pass a command line to the utility. I would like to set it up so that the utility will not run independently but only run and load its only form (Form1) if it is launched by the primary app using a "/run" command line parameter. (I can set up the primary app to launch and pass a command line parameter. I need help with the utility's code.)
The utility already has some VB code, so I need to figure out what code to add to receive and act on the " /run" command line and even more challenging for me, where to place this new code so it works.
pseudo-code:
initial event to read the command line, then if it is " /run" load Form1, else do not open and run utility app.

Recently, I just helping my friend for developing game private server, in Game Client there are 3 application is needed, its is a patcher, launcher, and main exe, my friend use open source (C++ language) application for the patcher, the patcher is work nicely, and the launcher is program that launch main exe, its using launcher because main exe is need some argument to run, the launcher is created by me.The problem is the user can be run game directly without opening the patcher, so I want to change default command line (usually "0" / "1") in launcher to 3, and I have the trap if user open directly the launcher
If My.Application.CommandLineArgs.Item(0) = "3" Then
MsgBox("Please Run Patcher to proceed the game!")
End

Can VisualStudio VisualBasic be opened with a command line argument specifying a custom constant for conditional coding? Instead of specifying it at "properties > Compile > Adv Compile Opts > Custom constants", I would like to just run a .BAT file that opens VisualStudio/VisualBasic and my source code with the "Custom constant" already set for the conditional coding.

I've been trying to figure out how to do this but with little success.I need to build a function that does this but I've never built a function before.Here is what I have but it tells me it may result in a null exception.(Because I'm not doing something quite right.)[code]

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)

If I try to display a command line argument that has double quotes around, the double quotes are always stripped off. How can I avoid this?
for example, the argument is "c:xx.txt" and this displays c:xx.txt instead Console.WriteLine((My.Application.CommandLineArgs(4)))

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?

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]....
