Local Option for Hotkey

This one if possible makes the hotkey enabled app a good windows citizen.
One can work around by getting the current state of the dialog if it's a foreground window but still the hot key of a different app will be lost as VDS has already captured it.
I don't know if that is feasible if this is dependent on a third party component.
Also Hotkey needs that a dialog be shown for it to work.

(I used GetKeyState API in conjunction with window state (foreground or not to achieve this - under a timer) If built in function is possible that s nice.

VDS 5 implements global hotkeys only. I expect that a dialog has to be present for a reason.

You might be able to implement local hotkeys using OPTION MSGEVENT,$0102,WM_CHAR

What you can do is check if the window is in focus in a loop, and if it is not,
use HOTKEY REMOVE and if it is in focus, use HOTKEY ADD so that it is only
a hotkey when your window is active. Smile

Thanks Jules this message works with OPTION MSGEVENT Very Happy

The W param contains the character code of the key pressed.
But I can use VkKeyScan to conver it to Virtual key code.

FF Good Idea Thanks Smile

only thing is timer will consume many more CPU cycles than the idea given by jules I think.

Actually you're just fine with a timer. As long as you don't use a wait time
of zero it uses hardly any CPU time. Smile

FF I like your idea... Simple and effective. I wanted to do that for a long time.

Thanks to Jules also... Very Happy

Hi CodeScript,

Would it be possible for you to post an example of how to implement this so I can determine, locally, if the Return button has been pressed down?

Thanks,

- Boo

Hey guys,

I thought there was a dll hotkey, global, <1> in the vdsdll28.dll Smile

Perhaps you could use that one Wink

Regards,
Vic

Hi Vic,

Yeppers, that is correct. I was worried about compatiability of the DLL with VDS 5.0. Anyway, yesterday I decided to try the vdskey.dll v.2.8.

So far so good. FYI: I needed a local hotkey, not a global one. In essence, I need the user to be able to enter a search query and then be able to hit the Enter key while the focus is still in the edit box.

Here is some sample code using OPTION MSGEVENT. Is there a better way of accomplishing this?

Cheers,

- Boo

You can place a BUTTON on your dialog either visible or hidden and give it a DEFAULT style. When someone presses the ENTER key that button is always executed.

Cool; thanks! (Duh!)

I knew there must be an easier way... Wink
