Thread: keybd_event() problems

hello all, i am creating a simple macro program and have stumbled uppon a few small problems...

number 1, i can emulate special chars such as '/' (VK_SLASH)

i have tried a number of ways to fix this buy cant get it working,

VK_SLASH returns as an undeclared identifier so i have tried:

keybd_event('/',0,0,0);

and have also tried above with a toupper(), and also with a vk_shift before it, cant get it to work tho

my second problem, is i cant figure out how to press and hold a key with code.

i have tried:

Code:

keybd_event(key,0,0,0);
Sleep(10000);
keybd_event(key, 0, KEYEVENTF_KEYUP, 0);

but that only presses the key once then waits 10 sec then moves on.

i have tried it in a for loop too

Code:

for(int i=0; i<10000; i++)
{
keybd_event(key,0,0,0);
}
keybd_event(key, 0, KEYEVENTF_KEYUP, 0);

and also:

for(int i=0; i<10000; i++)
{
keybd_event(key,0,0,0);
keybd_event(key, 0, KEYEVENTF_KEYUP, 0);
}
(trying every possible solution)

all that does is press the key 10,000 times super fast, its not the same as holding it down. technically i could be the same as holding it down as far as text programs are concerned, but all it causes are freezes/slowdown in graphical hands free presentations.

thx in advance for any light shed on my problem.

i actually found your site on google the other day hehe, im going to check out google for a scan code list.

well, found scan code, tried scan code... and no dice,

tried

Code:

	keybd_event('/', 0x35, 0, 0);
	keybd_event('/', 0x35, KEYEVENTF_KEYUP, 0);

and also tried

Code:

	keybd_event(VK_SLASH, 0x35, 0, 0);
	keybd_event(VK_SLASH, 0x35, KEYEVENTF_KEYUP, 0);

which still gives an undeclared identifier.
