How to accept input into a vb.net console application? How Do I allow people to type into a vb.net console application, and then press enter, and then the console application writes that and uses the console.writeline function to write what the person typed in into the network stream(or whatever its called).

I have a procedure at the end of my console application that ask the user to either hit enter to end the program, or type s to perform another search. The issue I'm having is no matter what the user types in the program end. What I would like to happen is if the user types s, then the program starts over and lets the user perform another search. The program is procedural and I need to find a way to start back off at the top of the program which ask the user to type a name to search.

I am maintaining some VB.net code and I am more of a C# programmer. I have taken over maintaining several projects from people who have since left the project. The manager tells me that some of the VB.net programs are console applications. Yet in looking through the source code I am not able to distinguish wether the code is for a console application or for some other VB.net program like a VB.net windows application. Can someone tell me if there is a way to determine if a VB.net program is a console application.

View 5 RepliesI work in an engineering design house and programming is not my actual profession. And I am relatively new to VB .net (previous i had worked in vb 6)
I am working on an in house application. I am coding a simple application in vb .net. This applications takes a few inputs from user and calculates a result. Now I want to implement a simple functionality that user should be able to save the input and results just like most of the windows programs can in a new file format. And user should be able to open the save file when desired.
I am currently working on an application, where I am using a console application, that will set up the application prior to the main form is run. This is no problem I've got that all working perfectly, the only problem I have is that the console is showing while the application is running, I was wondering whether anyone knows any way in which I would be able to hide the console before it gets shown to the user.

I have all of the code written but when I run the program it pops up the console window and then immediatley exits so I am unable to read what is in the window to see if my program is operating correctly. This is the first time I've ever used a console window so I don't know where in the code I would need to put "whatever it is" I might need to put to keep the window open until closed by the user.
View 7 RepliesIt sounds confusing but it's not really. What I need is basically a way to emulate the console style text, without using a console. What I'm really doing is trying to do a matrix effect on my form background, by drawing symbols and moving them, alternating their colors (see this video for what I mean).
Is there a way to do this effectively with a timer and a draw event, with the timer calling the draw event and changing the intervals?
Okay so i want to build an application that "wraps" another, the app that i want it to read console reports stuff like
