Tuesday, June 05, 2007 3:23 PMGood day,
I have a code that moves the cursor in a specified x and y coordinates. When I run it, sometimes the monitor turns off but sometimes it works normally. Tested it on a different PC , instead their screen saver turns on upon running the program. Does anybody know what is wrong?

And when your program starts call the SystemParametersInfo with the SPI_SETBLOCKSENDINPUTRESETS, so that the screensaver will not be activated while your program is using the SendInput() function.

What will happen if you disable the screesaver and then run your program.

I've got the same/similar problem
I'm using SendInput(mouse stuff) to simulate user input for testing of a program I am working on.
if there is a screen saver enabled on the PC (XP,2003,Vista), then frequently the screen saver starts when I use SendInput - not after the screensaver timeout (which is 15mins) - and if power saving is enabled on the monitor, then the monitor also shuts off.
it is happening within seconds of me starting that function of the program.
I have tried adding
but no different.

I had exactly the same problem with my application - built with Delphi XE2 - with SendInput-function at XP, Win7 and Win8.
Now, when I use ZeroMemory-function for tagINPUT-structure before feeding mouse xy-coordinates and flags to it, screen stays on normally. So weird..as far as I know Delphi should reset the memory area used beforehand. Thanks for the link!
