No you don't need to duplicate handle if you have enabled inheritance int the CreateEvent of parent process setting lpEventAttributes parameter.
You need a duplicated handle if the event is created in the child process.
For detailed info see[^].
is there a possibility to edit the year in the short format(yy) aswell?
I set the format "dd.MM.yy" and the date is shown correctly as "23.04.15"
But if I place the cursor in the year-section, the year switches from 15 to 2015.
I need that the year keeps 15 at the edit-mode.
I have upgraded my VS 2008 project to VS 2010 by opening the solution file and successfully built the project (debug and release configurations). But when I run the project within Visual Studio I get the following weird error saying:
"Unable to start program"
"System cannot find the file specified"
Without more information we have no way of guessing what may be wrong. Look in the directory tree for the project and check that the excutable actually exists. Try starting it from Windows Explorer to see if it runs.
