Disable Ctrl key , an hook question ?

[thangnguyen]

Hi,
I use hook to receive message sent to application A.when user holds Ctrl down and left-clicks on application A, I can receive this action with hook, but I don't know how to modify the message so that only left-click action was notified to app A.
I have tried to modify the wParam = MK_LBUTTON only, but it seems that when this message come to A, user is still holding Ctrl key, so A can aware of this full action with holding Ctrl key.
And the way I think is to disable Ctrl key before send message to A, and enable it later.
Do you have any suggestion ???

thank you so much,
Thang.

you should handle MW_KEYDOWN. John Fill

thanks for the info,
I have tried it but it doens't work. Is seems that at the moment app A is getting the message WM_LBUTTONDOWN, it gets the state of Ctrl key ( from function like GetAsyncKeyState ).
So even if I have prevent message indicating the pressed state of Ctrl key, app A still get the correct state. So my choice is not much, the solution may be still as I though : disabling the Ctrl key. But I still don't know how .....

thanks,

Thang.

just return without any actions if ctrl is pressed, and process message if not. John Fill

I don't understand exactly what you mean, all I have is from hook, I don't know what app A does with those messages, the only thing I could do is within my hookproc : prevent from sending to app A any message may include the state of Ctrl key : WM_LBUTTONDOWN with Ctrl key down, WM_KEYDOWN with Ctrl key down.
But it still doenst work at all !!!
