Win32::CtrlGui::wait_for_window is only partially working

marcz908 has asked for the wisdom of the Perl Monks concerning the following question:

Here is my code:

use Win32::CtrlGUI

my $window = Win32::CtrlGUI::wait_for_window(qr/Notepad/);
$window->send_keys("!fx");
[download]

This is actually the same exact code that appears in the POD. When I run the program, it blocks, then I open notepad, and the call returns, but $window is null. This is confusing because it obviously found the notepad window opening. Does anyone have any insights?

Thanks!

Putting a semicolon after the `use Win32::CtrlGUI` line seems to fix it. Without the semicolon, I got an error on the `send_keys` line. With it, everything worked.	[reply] [d/l] [select]

Try inserting a pause: `use Win32::CtrlGUI; my $window = Win32::CtrlGUI::wait_for_window(qr/Notepad/); sleep 1; $window->send_keys("!fx");` [download] I had a similar problem, with an application that was taking too long to finish drawing it's window. If you had the same problem, you would have to check if specific fields inside the window are already drawn before sending keys.	[reply] [d/l]
