How can I simulate Ctrl Alt H?. Nothing happens when I run this code : keybd_event((byte)Convert.ToInt32(Keys.Control), (byte)MapVirtualKey(Convert.ToInt32(Keys.Control), 0), 0, 0);
keybd_event((byte)Convert.ToInt32(Keys.Alt), (byte)MapVirtualKey(Convert.ToInt32(Keys.Alt), 0), 0, 0);
keybd_event((byte)Keys.H, (byte)MapVirtualKey(Convert.ToInt32(Keys.H), 0), 0, 0);
keybd_event((byte)Keys.H, (byte)MapVirtualKey(Convert.ToInt32(Keys.H), 0), KEYEVENTF_KEYUP, 0);
keybd_event((byte)Convert.ToInt32(Keys.Alt), (byte)MapVirtualKey(Convert.ToInt32(Keys.Alt), 0), KEYEVENTF_KEYUP, 0);
keybd_event((byte)Convert.ToInt32(Keys.Control), (byte)MapVirtualKey(Convert.ToInt32(Keys.Control), 0), KEYEVENTF_KEYUP, 0);

If you are like me and have been searching every where for how to do this?
All you need to do is change the Source Code above to use the Make value instead of Break Value.

Change Above example from
keybd_event(VK_TAB,0x8f,0 , 0); // Tab Press
keybd_event(VK_TAB,0x8f, KEYEVENTF_KEYUP,0); // Tab Release
to
keybd_event(VK_TAB,0xf,0 , 0); // Tab Press
keybd_event(VK_TAB,0xf, KEYEVENTF_KEYUP,0); // Tab Release
Changing break code 0x8f for tab to be 0xf allowed me to send tab key to Citrix client.

This should keep the left-key pressed until I click button2:
<br />
[DllImport("user32.dll")]<br />
static extern void keybd_event(byte bVk, byte bScan, uint dwFlags, int dwExtraInfo);<br />
<br />
private void button1_Click(object sender, EventArgs e)<br />
{<br />
keybd_event(0x26, 0x45, 0, 0);<br />
}<br />
<br />
private void button2_Click(object sender, EventArgs e)<br />
{<br />
const int KEYEVENTF_KEYUP = 0x2;<br />
keybd_event(0x26, 0x45, KEYEVENTF_KEYUP, 0);<br />
}<br />
<br />
But it only presses left once. Whats wrong?

hello
at first i am very sorry for my bad english.
i was must develop one application, which should send keystrokes to the dos application ( classic dos window in win xp)
sendkeys() can send keystrokes but, it cant simulated keystrokes between {F1} - {F12}
and that was very problem for me.
i solved this problem, for interesting:
private void sndks(int key)<br />
{<br />
const byte KEYEVENTF_KEYUP = 2;<br />
<br />
int ScanKey = MapVirtualKey(key, 0);<br />
<br />
keybd_event(0x76, (byte)ScanKey, 0, 0);<br />
keybd_event(0x76, (byte)ScanKey, KEYEVENTF_KEYUP, 0);<br />
}
KEYEVENTF_KEYUP = 2; release the key
this function send to the dos window any char
regards

1. When I was sending the number 6, it actually only worked with the "Make" code versus the "Break" code like the article says. I don't know about letters, I only tried the numbers 6-9.
2. If you don't want to hardcode/look up the scan codes, just use something like this:
<code>
void SendKey(char c) {
WORD vkey = VkKeyScan(c);
BYTE scan = MapVirtualKey(vkey, 0);
keybd_event(vkey,scan,0,0);
//and of course, if you want to do the whole keypress event
keybd_event(vkey,scan,KEYEVENTF_KEYUP,0);
}
</code>

I would like to know how to simlulate press and hold a character key?
For example, if we were to press down a character key, say 'a', on Notepad. 'a' will shows up until we release the key. Is there any way to simulate it?
Thanks for your help.

Yeah, I'd like to know how to do this as well.
|
|
|
|
|
But where can I get the keybd_event() function to use it?
|
|
|
|
|
OK, I understood - it is in windows.h

Hello, I´m trying to do an application in c++ which It send the secuence Ctrl+Alt+Del. The code is:
keybd_event(VK_LCONTROL,0,0 , 0);
keybd_event(VK_MENU,0,0 , 0);
keybd_event(VK_DELETE,0,0 , 0);
::Sleep(50);
keybd_event(VK_DELETE,0, KEYEVENTF_KEYUP,0);
keybd_event(VK_MENU,0,KEYEVENTF_KEYUP,0);
keybd_event(VK_LCONTROL,0,KEYEVENTF_KEYUP,0);
but it doesn´t work.
Can help me? Thanks.

keybd_event is not working with ctrl+alt+delete keys simulation. I too agree. Let me have some time to work on it to get a solution. But you can lock your system using WinKey+'L',
keybd_event(VK_LWIN,0, 0 , 0);
keybd_event(VkKeyScan('L'),0xa6,0 , 0);
keybd_event(VkKeyScan('L'),0xa6,KEYEVENTF_KEYUP , 0);
keybd_event(VK_LWIN,0,KEYEVENTF_KEYUP,0);
or if you want to bring task manager, use "Ctrl+Shift+Esc"
Hope it may help you...
Thanks,

How can I send Ctrl+Alt+H. Nothing happens when I run this code :
keybd_event((byte)Convert.ToInt32(Keys.Control), (byte)MapVirtualKey(Convert.ToInt32(Keys.Control), 0), 0, 0);
keybd_event((byte)Convert.ToInt32(Keys.Alt), (byte)MapVirtualKey(Convert.ToInt32(Keys.Alt), 0), 0, 0);
keybd_event((byte)Keys.H, (byte)MapVirtualKey(Convert.ToInt32(Keys.H), 0), 0, 0);
keybd_event((byte)Keys.H, (byte)MapVirtualKey(Convert.ToInt32(Keys.H), 0), KEYEVENTF_KEYUP, 0);
keybd_event((byte)Convert.ToInt32(Keys.Alt), (byte)MapVirtualKey(Convert.ToInt32(Keys.Alt), 0), KEYEVENTF_KEYUP, 0);
keybd_event((byte)Convert.ToInt32(Keys.Control), (byte)MapVirtualKey(Convert.ToInt32(Keys.Control), 0), KEYEVENTF_KEYUP, 0);
