LaunchProgram()

Starts a Windows program.

In Version 2016 added the Display option.

In Version 2021 added Input and Output options.

LaunchProgram(string command_line, opt array options)

Argument	Contents
command_line	The command line used to run the Windows program; the same string you would type into the Windows Program Manager File/Run dialog

Option	Type	Contents
Display	String	How to display the application window: "Hidden", "Normal", "Minimized", or "Maximized"
Input	String	Filename from which Standard Input is redirected
Output	String	Filename to which Standard Output is redirected
Error	String	Filename to which Standard Error is redirected

The options array is an optional argument.
The launched Windows program runs normally, as though it is run directly from the Program Manager using the option you choose.
See RunProgram() for a description of the search algorithm used if no path is specified for the executable file for the Windows program.
LaunchProgram() does not wait for the program to end. Use RunProgram() if you need to halt the GISDK execution while the program runs.
If an error occurs, GetLastError() will list the Windows error code. The Error option can be used to redirect error messages.
If the Display option is not specified, LaunchProgram() uses the "Normal" option by default.

command = "notepad myfile.txt "

opts = {{"Display", "Maximized"}}

on error do

ResetCursor()

ShowMessage(GetLastError())

Return()

end

SetCursor("HourGlass")

LaunchProgram (command, opts)
