hi, i've created a console ( hmm, not bad ) but seems i got a problem, all keys are inserted twice! if i type "quit" it would be on the console as "qQuUiItT". and of course the enter key enters two commands into the console did i missed somthin overhere? this is how i do it: 1) switch (Msg) 2) case WM_CHAR: 3) console.insert(wParam); if this is a silly question, please help me i am not a programmer, i am a mechanical engineering student. ( and this is my hobby ) ... :'( "The Railgun Master" DaHeR Edited by - DaHeR on January 15, 2002 10:21:01 AM

i don''t use console functions much. but i presume if you remove the ".insert(wParam)" that will fix that. most likely your keypresses are automatically echo''d to the console.

It is because your game is checking keypresses too quickly. The console is checking keys at what, once every millisecond (or even more), and when you press down a key, you hold it down long enough for it to process 2 keydown messages for that key you pressed.

Either you can limit the speed, or just set that key''s flag to false after you''ve processed it the first time.

thanx for replying...

but are u saying that i have to process all the keys being held and turn off the keys processed?
dont u think that this idea makes my game very slow?
and heh, if the user pressed ''a'' i have to check the shift status to determin ''a'' or ''A''...

there should be a problem with that, belive me

does any one else gorra better idea?

Hey

I''ve got a working console and all I did was when a key was input I got the current time (using GetTickCount. The next time a key was pressed if the currenttime - previoustime < 100 (milliseconds?) then I don''t input it else I enter that key.

Works for me

I tink WM_CHAR will be sent to ur program upon keydown and keyup...

Yeah, i think TheGilb is right. WM_CHAR probably does come up every time you press or release a button (but this doesn''t explain why one is a capitol letter and the other isn''t). I think your better of using WM_KEYDOWN.

oh i think i am very sorry...

after reading the code 6 times

. i found the problem.
the problem was :

switch(msg)
case WM_KEYDOWN:
{ do somthing }
break; <- i forgot this

plaese forgive me...
case WM_CHAR:
{ do the console }
break;

again i am sorry...

n/p. may i suggest the "Ctrl+F10" option with VC++. it does wonders.
