I want my WPF application run just one time. I have no problem with this.
My problem is how can I determine if windows currently restarted?
You could write a file to disk, and then immediately mark it as 'delete on reboot' using MoveFileEx:
So in psuedocode:
if(File.Exists(CheckFileName))
return false; // already ran once
else {
// write out the check file
using(checkFile = File.Create(CheckFileName, ...)) {
// and mark it as delete on boot
MoveFileEx(checkFile.SafeHandle,
null,
MOVEFILE_DELAY_UNTIL_REBOOT);
return true; // ok to run
}
}
You could check and store the system uptime along with the last runtime and compare that with the current uptime.
Retrieve system uptime using C#
Some psudeocode:
DateTime computerLastStarted = Now - Uptime;
if (computerLastStarted > storedComputerLastStarted + or - tollerance) {
storedComputerLastStarted = computerLastStarted;
StartProgram();
}
