If you need to close the formerly open documents, then you have to terminate the process whose handle corrensponds to the one returned (if any) by hProcess member of SHELLEXECUTEINFO. But gracefully terminating such process isn't a simple task (at least IMHO).

Now the problem is that when there is no filename a message shows that "this file name does not exist" .

set SEE_MASK_FLAG_NO_UI to fMask of SHELLEXECUTEINFO to avoid getting the error dialog

And why don't you simply check if the file exist before opening it ?

How do you open your file ?
Where is this message coming form ? Do your program display it ?

1. Copy paste the above code into your project.
2. Change the path of the file name.
3. Compile and run.
4. I pity your employer.

well, it means you are lucky not to have john simmons replying to your posts. Rajesh's reply was kind to you. If you think Rajesh's words were hard to digest and it hurt you, then I am sure you will be hurt more if john replies to you. Beware of his wrath.

Then ask questions about what you are not understand about it rather than asking your original question over and over again. That'll get you ignored real fast.

What's to search for? The code has been provided...multiple times.

I don't get enough time to spend here on CP forums these days. But whenever I visit here, I see you posting this question for at least couple of times in a day. Mad | :mad:

You asked the same question a couple of days back and you are still working on that? even after receiving so much help to finish off that task? I assumed you to be a student, but I am surprised to see that you are an employee. WTF | :WTF:
