Hi,
I'm working on an application to detect a pop-up dialog and then
automatically dismiss it. I'm writing this as a C++/Win32 app. The
dialog box is generated by IE 7 and I can detect the window, but
several methods to get the OK button to "click" have failed.
Doing searches for other people's solutions, sending these messages to
the button handle seems to have worked in a lot of situations:
PostMessage( handle, WM_LBUTTONDOWN, 0, 0 )
PostMessage( handle, WM_LBUTTONUP, 0, 0 )
PostMessage( handle, BM_SETSTATE, 1, 0 )
It has no effect on the button state in my tests though.
I can send tab characters to the main window and see that the OK
button gets focus, but then sending return characters does nothing.
To learn more about this I used Spy++ to get information about the
window hierarchy and what messages are delievered when I manually
click the OK button.
Looking at the message log and reading about WM_MOUSEACTIVATE seamed
to offer a solution. The log info shows that 0002166C was the button
window. So in my code I tried this:
GetClassNameA( handle, str, str_size );
if( strcmp( str, "Internet Explorer_Server" ) != 0 )
return TRUE; // Not the window we're interested in.
// Send a message to activate the button window and have it process a mouse click.
PostMessage( handle, WM_MOUSEACTIVATE, (WPARAM) dialog_handle, MAKELPARAM( HTCLIENT, WM_LBUTTONDOWN );
Based on the window hierarchy and message log, I think the window with
the class name "Internet Explorer_Server" is the button. Maybe I'm
wrong, because it does seem like an odd class name for a button...
Below is a link to the window hierarchy image, message log when I
manually click the OK button. Last is the code that's executed on a 1
second timer ticket, looking for the window.
Any insight and help is appreciated!

I'm working on an application to detect a pop-up dialog and then
automatically dismiss it. I'm writing this as a C++/Win32 app. The
dialog box is generated by IE 7 and I can detect the window, but
several methods to get the OK button to "click" have failed.
Doing searches for other people's solutions, sending these messages to
the button handle seems to have worked in a lot of situations:
PostMessage( handle, WM_LBUTTONDOWN, 0, 0 )
PostMessage( handle, WM_LBUTTONUP, 0, 0 )
PostMessage( handle, BM_SETSTATE, 1, 0 )
It has no effect on the button state in my tests though.
I can send tab characters to the main window and see that the OK
button gets focus, but then sending return characters does nothing.
To learn more about this I used Spy++ to get information about the
window hierarchy and what messages are delievered when I manually
click the OK button.
Looking at the message log and reading about WM_MOUSEACTIVATE seamed
to offer a solution. The log info shows that 0002166C was the button
window. So in my code I tried this:
GetClassNameA( handle, str, str_size );
if( strcmp( str, "Internet Explorer_Server" ) != 0 )
return TRUE; // Not the window we're interested in.
// Send a message to activate the button window and have it process a mouse click.
PostMessage( handle, WM_MOUSEACTIVATE, (WPARAM) dialog_handle, MAKELPARAM( HTCLIENT, WM_LBUTTONDOWN );
Based on the window hierarchy and message log, I think the window with
the class name "Internet Explorer_Server" is the button. Maybe I'm
wrong, because it does seem like an odd class name for a button...
Below is a link to the window hierarchy image, message log when I
manually click the OK button. Last is the code that's executed on a 1
second timer ticket, looking for the window.
Any insight and help is appreciated!
