Button Keypress 'd

[jonah]

hi,

im using this code to simulate a leftmousetclick to a particular window (button) using an API

SendMessageLong(BtnHwnd, WM_KEYDOWN, VK_SPACE, 0&)

It does what is supposed to do. i didnt send the the Const WM_KEYUP = &H101 so that the button remains pressed.

My problem is when i move the target window or just click or type anything on the form of the target window it released the mouse left click. I even tried to disable that window but it still released the button when it move.

is there a way so i can lock that window so it wont release its keypress hold on the button? or do i have to use a timer control then keep sending that message to that window???

tnx

try to put a mouse_left_button _flag. and tell it to your program that if the 1st press encountered, mouse_left_button _flag = true. Then the keypress to your target will be like this;

if mouse_left_button _flag then
<nothing>
else
<release keypress>
endif

and if the 2nd press encountered to your mouse, mouse_left_button _flag will be false.

I hope I get it right.

Is the target window a part of the app you are developing, or is it an external window in another app?

its in another application

its something like this

Private Sub cmdbutton_Click()
Select Case cmdbutton.Caption
Case Is = "LOCK BUTTON"
cmdbutton.Caption = "UNLOCK BUTTON"
Call SendMessageLong(BtnHwnd, WM_KEYDOWN, VK_SPACE, 0&)
Case Is = "UNLOCK BUTTON"
cmdbutton.Caption = "LOCK BUTTON"
frmMAIN.cmdbutton.Caption = "LOCK BUTTON"
Call SendMessageLong(BtnHwnd, WM_KEYUP, VK_SPACE, 0&)
End Select
End Sub

it does press the button on another app but when the target application moves (or it recieves another message i think????) the keypress on the button gets released.

I want it to press the button and keep holding it down (keydown) until i say to release it (keyup).

Why? What are you attempting to achieve by doing this?

Actually its a Talk Mic Button. I want to lock it on keypress so i wont have to use the mouse to keep it holding it down

When i send the message

SendMessageLong(BtnHwnd, WM_KEYDOWN, VK_SPACE, 0&)

it does hold down the button if i dont send the WM_KEYUP. But it releases the button when the target app moves or when i type something on that app.
