Console application

[brew]

So i made this console application and in order for the program to stay active, i have to run a constant loop.
this is VERY cpu consuming, and when I tried to connect to bnet with it, it took about 7-8 seconds. (if i commented out the loop it would connect much faster, but not work after that.)

Private Const STD_INPUT_HANDLE = -10&
Private Const STD_OUTPUT_HANDLE = -11&
Private Const STD_ERROR_HANDLE = -12&

Sub Main()
    Show
    Do
        DoEvents
        Select Case ReadText
            Case "/exit": Hide
            Case "/connect"
                frmMain.WS.Close
                frmMain.WS.Connect "213.248.106.200", 6112
                AddChat vbForeYellow, "[BNET] Connecting..."
        End Select
        DoEvents
    Loop
End Sub

Public Sub Show()
    AllocConsole
    SetConsoleTitle "Console Test"
    hConsoleIn = GetStdHandle(STD_INPUT_HANDLE)
    hConsoleOut = GetStdHandle(STD_OUTPUT_HANDLE)
    hConsoleErr = GetStdHandle(STD_ERROR_HANDLE)
End Sub

so on...

Anyone got any ideas

Don't use VB for console apps?

[brew]

but... i like vb

[warz]

but... what you're trying to write is better suited for a different language

[brew]

acually you're right... the past two topics i've posted here pertains to things almost unheard of in vb6 and easy as hell in c/c++, but i still love vb if vb was a person i'd hug it
Uhh and btw i believe the way consoles in C work the same way, except they have a break(); (or something) at the end of execution, so it doesn't exit until it receives input (a key press) So i think the entire thread is paused in C, too. You just don't notice it. (correct me if im completely wrong) Yeah, using a console was a bad idea. Anyone know where I can get the "raster fonts" that console uses?

instead, you could use CreateWindow() and code the application window, then implement a callback function

I acually tried that-- by using form_Load on startup, then calling sub main(). Now it no longer exits immediately, but the console window that is "spawned" is now "inactive" (no input/output). It seems like I no longer have a handle on that console window (but i know i do, i would have to. I don't call freeconsole() until hide, which is only called upon exit command)

is a console application necessary, or are you just interested in not using forms? you can simply call CreateWindow() and RegisterClass() to make a window and then work with calls from the callback function. But if you don't want to do that, why don't you just implement like a Sleep(1) call as to not get owned by the intensity of an infinite loop.

One thing is to remove DoEvents.

one thing one thing one thing, boo hoo

ok, please you try that

Wow, i just tried the sleep api like you said and it worked absolutely perfect. (although i'm not exactly sure why/how) Thanks, shadow.

Edit*
It doesn't work after you enter text 3 times. And if I use the loop way, which is guarenteed to work, it doesn't connect. What gives -_-

VB.NET.  Console.ReadLine() blocks the thread while in a loop preventing massive CPU usage.
