What does VB.Command() does in .NET

Hi all, I was given a project to covert a VB application to VB.NET type. It went on well and there was no error after solving certain minor issues related to DLL.

My question is I found a command that was commented to receive the process id. I was totally unsure of this. The command goes like this.

string strProcessId = VB.Command()

The string was expected to receive a process_ID, but it never does and always displayed as an empty string.

I am not bothered about the process now.
All I wanted to know is what does the command VB.Command() returns?

It all depends on what object is VB?

AFAIK, VB is not a standard object that we can tell you looking at the line. You need to see and find about VB type first and then a simple Google can tell you about the command.

It is a statndard object in Vb. You can create in any VB project.
Here the VB as you said is an import which imports vb comands.

According to Microsoft :

"Returns the argument portion of the command line used to launch Microsoft Visual Basic or an executable program developed with Visual Basic."

If you launch your app :
YourApp.exe 12345
It returns "12345"

Cheers

Hi Estys,
The problem is the command always returns NULL in any sample project. Can you brief your explanation more.

My sample app goes like this in .NET

messagebox.show(vb.command())

the result is empty messagebox

My sample app in VB is

msgbox(Command())

which is also an empty messagebox.

If you don't start your app with arguments, the string will be empty. If you run it from within the IDE, you can set an argument-property of the project IIRC.

I don't know if it works the same way in VB.NET, my remarks were towards the VB6 function.
