So in my project, I have buttons for selecting an action that a python project will do. When I do the command "py project.py -l query" it only shows the help menu what appears when I do "py project.py". I checked and found out I need to change my code "psi = New ProcessStartInfo(Setting_Data.Text.Split(" ")(0), Setting_Data.Text.Split(" ")(1))" to split the text into more parts but If I add more splits I get the error "Overload resolution failed because no accessible 'New accepts this number of arguments." Does anyone know how to fix this?

What I have tried:

psi = New ProcessStartInfo(Setting_Data.Text.Split(" ")(0), Setting_Data.Text.Split(" ")(1), Setting_Data.Text.Split(" ")(2))

Solution 1

ProcessStartInfo Constructor (System.Diagnostics) | Microsoft Docs[^]

There is no constructor of the ProcessStartInfo class accepting more than two strings as parameters.
You need to separate your input into two fields: executable name and command line arguments; thus, splitting it on whitespaces may not be the best way to go. Having an example of the input string would help suggesting a way.

@phil.o, for an example of what I'm trying to do, is I select one of the commands, for example, "py project -l query" and it runs it through Cmd.exe. When I click the run command button it only runs the first two parts of the command "py project.py" what only loads the python script and doesn't do any of the commands but I need it to run the full command.

When you set us a new StartInfo, it only takes a max of two strings: the first is the filename of the application to run, and the second is all the parameters it needs to work on as a single item.

Split doesn't do that: it break the string on every occurence oif teh splitting character.
So your input string:

py project -l query

Gets split into four separate strings:

texy

py 
project 
-l 
query

Instead of using split, get the index of the first space, and use Substring:

VB

Dim cmd As String = "py project -l query"
Dim firstSpace As Integer = cmd.IndexOf(" ")
Dim exe As String = cmd.Substring(0, firstSpace)
Dim param As String = cmd.Substring(firstSpace + 1)

And then pass those to your start info:

VB

psi = New ProcessStartInfo(exe, param)
