问题 procedure TMainForm.KeyDown(Sender: TObject; var Key: Word; Shift: TShiftState); begin if (GetKeyState(Ord('Q'))<0) and (GetKeyState(Ord('W'))<0) and (GetKeyState(Ord('E'))<0) then ShowMessage('You pressed it'); end; the above event only work if the Focus set to the Main Form. if i run the application and keep pressing Tab and changing the Focus to any control on the Form it will disable this event until we change the Focus again to the main form ? the Question is how i can detect the three

Find out what process registered a global hotkey? (Windows API)

由 我的未来我决定 提交于 2019-12-29 02:17:12
问题 As far as I've been able to find out, Windows doesn't offer an API function to tell what application has registered a global hotkey (via RegisterHotkey). I can only find out that a hotkey is registered if RegisterHotkey returns false, but not who "owns" the hotkey. In the absence of a direct API, could there be a roundabout way? Windows maintains the handle associated with each registred hotkey - it's a little maddening that there should be no way of getting at this information. Example of

Register hotkeys in .NET - combination of three/four keys

由 久未见 提交于 2019-12-18 07:21:41
问题 I got stuck. Right now, I am using the following code to listen to hotkeys: [DllImport("user32.dll")] public static extern bool RegisterHotKey(IntPtr hWnd, int id, int fsModifiers, int vlc); [DllImport("user32.dll")] public static extern bool UnregisterHotKey(IntPtr hWnd, int id); protected override void WndProc(ref Message m) { if (m.Msg == 0x0312) { // whatever i need } base.WndProc(ref m); } and this function to register hotkey: Form1.RegisterHotKey(this.Handle, this.GetType().GetHashCode(

Detecting Ctrl+V with RegisterHotKey but not intercepting it

问题 I need to detect when a user presses Ctrl + V (regardless of window focus - my app will likely be minimised) but I must not stop the actual paste operation. I have tried a few things: (I am successfully binding to keystrokes with RegisterHotKey) I have: protected override void WndProc(ref Message m) { if (m.Msg == 0x312) hotKey(); base.WndProc(ref m); } and I've tried the following: void hotKey() { SendKeys.SendWait("^v"); //just puts 'v' instead of clipboard contents } and void hotKey() {

How do you register a custom Win+V hotkey on Windows 8?

由 与世无争的帅哥 提交于 2019-12-10 10:29:02
问题 It was possible to register the Win+V hotkey on versions of Windows prior to Windows 8. An example application using this combination is PureText. With the Windows 8 Release Preview I've noticed that Windows 8 has taken control of a lot of hotkeys involving Windows key, but Win+V doesn't appear to be used. The following code will allow me to register a hotkey for Win+CTRL+V: #include <Windows.h> int _tmain(int argc, _TCHAR* argv[]) { if (RegisterHotKey( NULL, 1, MOD_WIN | MOD_NOREPEAT | MOD

Acessing C# code in Powershell

由 允我心安 提交于 2019-12-08 13:25:12
问题 I want to use a system wide hotkey in my powershell GUI application. I found this C# code for registering a hotkey and integrated it in my script. The trouble is, because I can't fully understand the C# code, I don't know how to properly add the parameters for the registerhotkey method. The goal is: on key press SHIFT + ALT + Z execute the code in $hotkeyExecCode . [void][System.Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms") [System.Windows.Forms.Application]:

Register hot key that is already used

由 泄露秘密 提交于 2019-12-06 01:52:41
问题 Background: I want to listen to a hot key sequence ( Ctrl+Alt+Left ) globally, so I'm using: [DllImport("user32.dll")] private static extern bool RegisterHotKey(IntPtr hWnd, int id, uint fsModifiers, uint vk); This works great with many other hot key sequences, such as Ctrl+Alt+PageUp , Ctrl+Alt+PageDown , etc... But a problem occurs with Ctrl+Alt+Left , specifically. Problem: On one computer, it works just fine, like any other hot key sequence, but on a different computer, where Ctrl+Alt

RegisterHotKeys and global keyboard hooks?

问题 What are RegisterHotKeys and global keyboard hooks, and how do they work? I want to make a key to get focused on my application's Form (when it's minimized) and then focus on a textbox, so from what I've read I need to use the RegisterHotKeys function (that's a better solution for my needs), but i couldn't find how or where I can choose my own key (only one key - ESC ) and then command it to focus on my form, and then on the textbox. 回答1: Sample on how to use hot keys. class myform : Form {

Simulating CTRL+C with Sendkeys fails

问题 I have an odd problem with Sendkeys, what my application basically should do is that, when I press ALT + J , it'll simulate a CTRL + C operation (on any windows) to copy some highlighted text, however the CTRL + C simulation is not working.
