Question

How to simulate a Ctrl-A + Ctrl-C using keybd_event?

Because I am simulating a ctrl a + ctrl c on a webbrowser form to copy the entire contents on clipboard. i used the SendKeys.SendWait but it is not copying the entire contents!

This should work

[DllImport("user32.dll", SetLastError = true)]
static extern void keybd_event(byte bVk, byte bScan, int dwFlags, int dwExtraInfo);

public const int KEYEVENTF_KEYDOWN = 0x0000; // New definition
public const int KEYEVENTF_EXTENDEDKEY = 0x0001; //Key down flag
public const int KEYEVENTF_KEYUP = 0x0002; //Key up flag
public const int VK_LCONTROL = 0xA2; //Left Control key code
public const int A = 0x41; //A key code
public const int C = 0x43; //C key code

public static void PressKeys()
{
    // Hold Control down and press A
    keybd_event(VK_LCONTROL, 0, KEYEVENTF_KEYDOWN, 0);
    keybd_event(A, 0, KEYEVENTF_KEYDOWN, 0);
    keybd_event(A, 0, KEYEVENTF_KEYUP, 0);
    keybd_event(VK_LCONTROL, 0, KEYEVENTF_KEYUP, 0);

    // Hold Control down and press C
    keybd_event(VK_LCONTROL, 0, KEYEVENTF_KEYDOWN, 0);
    keybd_event(C, 0, KEYEVENTF_KEYDOWN, 0);
    keybd_event(C, 0, KEYEVENTF_KEYUP, 0);
    keybd_event(VK_LCONTROL, 0, KEYEVENTF_KEYUP, 0);
}
