VB.NET: Console.Writeli ne() to DOS prompt when Forms app invoked from DOS

[TuckerRoth]

This is my first post on this site, so I don't know the rules. Please correct me if this gets to the wrong folks...etc.

PROBLEM: Many of the apps that I am writing need to be able to run 2 ways: They might be invoked from the command-line with parameters so that they do not show UI, but accomplish some task; OR they might be double-clicked, in which case they show a UI (so that the User can configure settings for the app...etc.).

To this end, I create the application as a Forms Application, but have a module that contains a

Public Sub Main(ByVal args() As String)

...procedure as the 'Startup object'.

If the app is double-clicked, there are no 'args', so I just ShowDialog() on the Main Form.

If the app is run from the command-line with args, then I don't ShowDialog() on the MainForm, and just do the work.

OK so far.

QUESTION: In the case where the User runs the application from the command line, I would like to write output to the DOS window (for ex: if they enter the incorrect args, then I want to display correct usage). But Console.Writeli ne() doesn't put output to the DOS window that the app is being run in?

How can I acheive this?

Am I wrong in doing things the way I am doing them with regards to my strategy of using a Forms Application but starting it with a Sub Main? Should I have created a Console application that somehow displays Forms?

Any help greatly appreciated!

if your program type is set to windows application (go to the properties of the project) then for some reason the "console" never runs correctly. Set it to a console application and you should see your output in the commandline that the program was invoked in. (Yes, you will still be able to do the showdialog() even in a console application.... unless they changed something without me noticing)
