I have a file called Test.txt with a one line of String equal to 'This is String', and I've created a command line argument to compare the MD5 results, why am I not getting a match?

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:

How, can i pass any command line arguments (Through Run Command)pass when my VB application execute and that's valuesare receive when form activate.
View 12 RepliesI 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.
I want to receive command line argument in my application like this.I have two different projects A and b when i execute A it should give an error message ( No Arguments ) but if i executes the project B ( it should pass a command line argument and the project A should start normally. the problem it that i can start application with arguments but i do not know how to receive arguments and execute different processes.
View 1 RepliesRecently, 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!")

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.

How would that work? I can't find any documentation in the MSDN.you know how when you open a txt file it opens up notepad and loads the file? how does the whole 'loading the file' thing work in VB?

View 8 RepliesI am trying to develop an application and am still learning VB. I have a commandline that will list some applications that I need to make selectable to run certain processes based on what is selected. I have already found the MSDN stuff on using the RedirectStandardOutput class to add to streamwriter. What I need to do is read each line and add to a listbox so that the user can select each application. How to read each line of the stream and add to a listbox.
Here is that code.

View 4 RepliesIf 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)))
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'm creating a dance mat game and I have a text file of the steps that should be taken to get a perfect score and a text file of the actual steps taken by the user. Each text file contains a time stamp and a binary value indicating which arrow was stepped on. I'm using streamreader and streamwriter to write and read the text files.

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.

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.

Using VB 2010 Express. I'm having trouble executing an .exe from my application with command line arguments. It works in the desktop shortcut but passing it from my application it's just writing %username% in and not pulling the username as if it was doing it in cmd line. Here is the path/arguments as we use them currently in a desktop shortcut:
"C:program.exe" /z app /s 1.1.1.1 /p 29091 /a U=%username% It all works fine other than %username%

I have a client application that has been in use on about 14 workstations for nearly a year now. on the admin side the old app works correctly but the new one comes up with an error stating a column (Job_ID auto increment primary key) in the database does not exist when inserting a new job record yet it still adds the job to the database. all information is correct. The estimation side does not come up with this error and all computers in both departments run the same exact application installed from the same disk. all issues seem to be related to the jobs table only. But the same workstations with the column not existing error on admin side have a different setup on the network and will not allow a desktop icon to be created by the new application or manually.
View 2 RepliesI am working on a simple program called "Who's Connected?" where it runs a command (netstat -aon) and then displays the results in a multi-lined textbox. However, when I press the button that will run the command, it tells me that it can't convert the string to an integer or something. And when I did manage to get it to convert to an integer, it really showed an integer in the textbox instead of the connections and IP addresses. What do I do? Here is the code I have: Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click 'Running command and displaying results in textbox1 TextBox1.Text = CStr(Shell("netstat -aon"))'Results end up being a triple or quadruple digit number End Sub

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)
1. Is their a way that i can capture the command prompt results and place it in a richtextbox?
