C# - Make A Windowless / Command-line Application Return But Continue Executing In Background?
Feb 15, 2011
I'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.

I have a normal windows forms application. A button launches a command line application.I need to insert an argument automatically without the keyboard. Then hide the command line application. 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]

I'm trying to create a program that does the following:Executes the following command line string (wmic /node:computername bios get serialnumber)Prompts user for the "node" entry Displays the resulting serial number in a dialog box I'm a bit of a noob at this (I haven't coded anything in VB since early 2000s) so I'm at a bit of a loss where to start. I plan on including some functions to submit the node entry and the resulting serial number to a database in the future for archiving as well.

Okay, so a program I've been working isn't running correctly. The application freezes and doesn't continue onto the next command (SetCursorPos(999, 999))
Here's my code:

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 was thinking I could make a console application that would have a FileSystemWatcher - watching for a .BAT file being created in a folder - and when it sees that file it does a PROCESS.START on it.

I was thinking I could make a console application that would have a FileSystemWatcher - watching for a .BAT file being created in a folder - and when it sees that file it does a PROCESS.START on it. But I'm seeing that a console app doesn't continue running.
Imports System.IO
Module awcWatcher
Sub Main()
Dim fsw As New FileSystemWatcher("D:ACS DesktopAWCeportingstaging")
fsw.NotifyFilter = NotifyFilters.FileName Or NotifyFilters.LastWrite

Starting from my understanding about Background worker control, I understands that the background worker runs the code in its "DoWork" method in a seperate thread, while ProgressChanged and RunWorkerCompleted events are executed on the main thread.In my senerio, I report the progress and under an specail condition my application displays a message box to the user in "ProgressChanged" method using MessageBox.Show(). and in "Run Worker Completed" event the application finalize some work. There the sequence is important, suppose that the message is of Yes or No type and finalization depends on it. Now when i run my application, the background worker triggers "ProgressChanged", but as soon as backgroundWorker's cancelAsync() is called the program leaves the current "ProgressChanged" method and executes "RunWorkerCompleted" code first.How can i make sure that the "Run Worker Completed" code executes only after the completion of ProgressChanged method.

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'm currently in the middle of a Console Application. I have done everything and it's ready to be handed in. However, I don't want to hand it in like this. I want to build upon it.
One of the ways I'd like to build upon this is with an e-mailing system. I'm find it hard to include the e-mail code in to the project and would like to request assistance. I'm uncomfortable posting the full code on the net as it is for my A-Level Computing and anyone that is doing the same course as me will be able to claim it to be there own.

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()

Is it possible to restart a VB.NET application, but with different command line arguments than it originally had? Here is the challenge. I want to write a single instance application. If the second instance has the same CL args as the first, then the built-in behavior is fine (second instance never opens, e.BringToForeground=True brings 1st instance to foreground, everything is great). But if the second instance has different CL args, then I would like the first instance to close and the second instance to start. However, once you mark a VB.NET app as "single instance only", it appears that you can never get the second instance. I think: OK, fine, I can just restart my first instance from the StartupNextInstance event. But how do I use the new command line arguments from the second instance? The Restart() method does not take CL args that I can see.

I have a VB.NET application that takes command-line arguments. It works fine when debugging provided I turn off Visual Studio's ClickOnce security setting.The problem occurs when I try to install the application on a computer via ClickOnce and try to run it with arguments. I get a crash when that happens (oh noes!).
There is a workaround for this issue: move the files from the latest version's publish folder to a computer's C: drive and remove the ".deploy" from the .exe. Run the application from the C: drive and it will handle arguments just fine.

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?

This is a easy one (i think) I am using MS access 2003 and. I am having problems continuing SQL statments to another line. I have been trying &_ and that doesnt seem to work with my SQL statements. How do I do this. I have some long SQL statments and it would be easier to break to another line, but I can't seem to do this. The statment below gives an error.
sqlz = "SELECT [Crosstab AUS].* INTO [AUS REQ] &_
FROM [Crosstab AUS]"
