.net - Disable And Enable Screen Saver In Windows 7?
Jan 18, 2010
I have an application than disables the screen saver temporarily in order to run a slide show. I use this to turn it on or off:
i = SystemParametersInfo(SPI_SETSCREENSAVEACTIVE, active, Nothing, SPIF_SENDWININICHANGE)
This works fine in XP. In Windows 7, it disables the screen saver properly. However, when it is enabled again, at the normal time for the screen saver to come on, the system asks for a password instead of showing the screen saver.From this time on until the screen saver settings are adjusted in the control panel, the password screen is displayed in place of the screen saver.Is there something else I should be doing for Windows 7? I understand that SPI_GETSCREENSAVEACTIVE is not supported in Windows 7, but SPI_SETSCREENSAVEACTIVE is supposed to be.

I have been playing about with the WM_SYSCOMMAND Message and more specifically with the SC_SCREENSAVE parameter which is a cool way to pick up when the screen saver is activated as seen below:[code] What I can't seem to find is if there is a way to detect when the screen saver comes off.

Our program works fine, until someone locks the computer or the screen-saver pops up (but not ctrl+alt+delete). Once the computer is unlocked/the screen saver is closed, the application stops drawing everything except the title bar, and stops responding to input - it displays a mostly-white window which can't be moved or closed.(Example of application freezing - the mountains are from my desktop background)If we let it sit for about 5~10 minutes, it comes back to life, and doesn't hang again (even after locking the computer/screen saver popup) until the application is restarted.

I have a vb.net based windows application, where when "GO" button is clicked a bunch of data is loaded into DB.

I populate a DataGridView during a sub routine. Later in my code I have a RowEnter event for that DataGridView when the user is assessing it after it has been populated during the main procedure. However this RowEnter event gets fired while the DGV is being populate. I only want it to file AFTER its populated. Is it possible to disable this specific event while the DGV is being populated? I really want the user to have the ability to cursor up/down the DGV and see affects of the RowEnter Event. I know I can also use the CellEnter event but it does not have the same effect.
