Command Line Program To End Before Moving Onto The Next Command In Loop?
Feb 4, 2011I 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.

C# - Make A Windowless / Command-line Application Return But Continue Executing In Background?
Feb 15, 2011I'm writing a command-line application in .Net. The app itself is fairly simple, but it has to connect synchronously to a web-service, which in turn has to connect to a Oracle database, and those pieces are fond of taking their time.
Is there a straightforward way (without dividing my app exe in two) to continue executing but nonetheless yield execution to the command prompt?
It's Windows, so no "&". Also, I cannot use cmd.exe's "start" cmdlet.
Command Line Strings - Make The Program Close If The -1 String Is Sent With The Program
Feb 25, 2010If e.CommandLine.Count > 0 Then
Dim IncomingCommand As String = e.CommandLine.Item(0).ToString
If IncomingCommand.Substring(0, 2) = "-1" Then
form1.close()
End If
End If
I am trying to make the program close if the -1 string is sent with the program. See my installer allows for me to run certain programs before it actually installs, but it doesn't shut down copies of the program itself. So I have a next startup instance set to shut the program down if the -1 is received. But if the program is not running it starts up instead. This is not desired. form1.close doesn't work. e.cancel = true doesn't work, etc etc. What can I do to make the program not start during this instance.
Convert Old GW-BASIC Program To A Command Line Program With Arguments?

Run A Command Line Program?
Mar 25, 2011I'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]....

View 4 RepliesCan't Save File Using A Command Line Program Using New Process
Oct 7, 2011I have been trying to fix this and make this work for pretty much three days now. I already solved one problem being, I can't use the shell on one HDD and create another file onto a different drive other then the drive that the directory of the application is running in.
EX:
If I run a program that is on the C: drive and using a working directory that is on the C: drive, I can not create a file onto the F: drive.
I got this problem when I was just using Shell(Environ$("Comspec") & " /c then the command")
So I decided to use Process()

VS 2010 - Developing An Automated Command Line Program - Attach The Timer ?
Feb 15, 2012The code in question is in place, and it works. The project is all but wrapping up. That being said, I would love to find a better way to run this section of code in an x64 system so I have the solution ready for future projects. What I currently have in place is as follows:
Function TimeDelay(vDelay)
Dim vTimmer, vTargetTime
vTimmer = TimeValue(Now)
[CODE]...
Now I know the easy way to achieve my goal would be to use the timer object in Visual Studio. The problem I ran into is I was developing an automated command line program. As such there was nothing I could attach the timer to (that I'm aware of). I just needed to pause the program for a few seconds to allow the DTSX package (SSIS file if you're not familiar) to load the file before I remove it from the staging folder.
While I was doing research for this issue I came across the old Sleep() function (referenced to a library in kernel32 as I understand it...never used this before either). When I tried to use this on my current system (64-bit system) I received stack overflow errors. Additional research lead to something called wow64, but I did not have enough time to fully research what this is / how to use it.
VS 2010 Can't Access Files Below Root When Using Process To Run A Command Line Program
Feb 4, 2011I am trying to create a program that downloads audio files via FTP, converts the audio to mp2 if necessary and copies them to a certain directory for consumption by our automation system. (I am a radio station engineer.)I am using the open source converter FFMpeg to convert audio files to mp2. This is a command line exectuted program. Here is the command line that I use to execute the external program with the input and output audio files at the root level: cmd.exe /k ""C:New Folderffmpeg.exe" -i "C:Test.mp3" -y "C:Test.mp2"" This command line works correctly whether I am using Shell() or System.Diagnostics.Process (Process) to execute the external program. I am going the Process route so I can know when the conversion has finished.Now, I really don't want to use the root directory for this but when I go below root with this line using Process the external program will not execute:[code]Can anyone tell me why that line will not work with Process though it works as expected with Shell()? I can't figure out how to stop the external program to get some feedback as to what its problem is.

Command Line Switches - Keeping Command Window Open?
Feb 24, 2010I 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.

.NET - Pass Command On Command Line?
May 29, 2012I 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)
