With spy++ find out that the window handle of the button, and then sends the message

 
If PostMessage (the window handle of the button, the WM_LBUTTONDOWN MK_LBUTTON, MakeLParam (10, 10))

Ask a question, if it has a few buttons, how to determine whether the button I need?

CodePudding user response:

Do you want to press the button to note down the handle to the button, the point that button will send message to the button

Var
BtnHwnd1 btnHwnd2: HWND;
The begin
//spy++ find such as a 'confirm' button on the handle
Handle btnHwnd1:=sure button;
//spy++ find such as a 'confirm' button on the handle
BtnHwnd2:=cancel button handle;

If PostMessage (btnHwnd1, WM_LBUTTONDOWN MK_LBUTTON, MakeLParam (10, 10))
And PostMessage (btnHwnd1, WM_LBUTTONUP MK_LBUTTON, MakeLParam (10, 10)) then
The begin
ShowMessage (' click confirm success);
end;

If PostMessage (btnHwnd2, WM_LBUTTONDOWN MK_LBUTTON, MakeLParam (10, 10))
And PostMessage (btnHwnd1, WM_LBUTTONUP MK_LBUTTON, MakeLParam (10, 10)) then
The begin
ShowMessage (' click cancel success);
end;

Thank you, this code can be used, the second problem can be done? Is on the contrary, such as external program click on the button, I need to send this message to return, this how to implement?

And PostMessage (btnHwnd1, WM_LBUTTONUP MK_LBUTTON, MakeLParam (10, 10)) then
The begin
//don't you click the confirm button here, what to confirm button to perform the nature is no way of knowing you
//you can only confirm if click on the button, and then do what you want to do
ShowMessage (' click confirm success);
end;

CodePudding user response:

Click on the button, to simulate mouse press and lift is unreliable, directly sending BM_CLICK message is king,

Of course, the premise is to find target button on the handle,

The webmaster, how to implement?

Master, I through
H1:=FindWindow (nil, 'UploadFTP');//h is the login window handle
H2:=FindWindowEx (H1, 0, PChar (' TBitBtn), PChar (' manual upload '));//button
To obtain the handle, but must be the target point up first, and then you can get to handle, but the target is to start automatically after the tray, this how to modify?
