Terminate external program

(0) ShareShare
ReportReport
Posted on by Morten Pelle Korsmo 160

I want to terminate/shut down an external program from C++ after printing a document. When printing a PDF document the program Adobe Reader remains open after printing even if the documents itself are closed.

The code snipplet:

WinAPI::shellExecute(DIRECTORY + "\\" + filename, '', '', "Print");

I have read about WM_QUIT(), Application.Quit(), TerminateApp() and TerminateProcess(), but all seams to require an ID of the opened application. As far as I can see, there is no such ID to be fetched.

Any ideas?

    hi

     the WinAPI::shellExecute returns an integer gives you the process handle you need.

    You can also use the Adobe Reader’s command line switch “/t” which activates the “silent mode” - it will print the file without showing any dialogs, and automatically close when finished. For that, you’ll need to call Adobe Reader’s executable (AcroRd32.exe) with “/t” follwed by PDF file as argument, for example like this:

    WinAPI::shellExecute(
        'C:\\Program Files\\Adobe\\Reader 9.0\\Reader\\AcroRd32.exe',
        '/t ' + DIRECTORY + '\\' + filename, '', '');

    AcroRd32.exe can also accept the printer (name, UNC, or IP address) as argument after the filename. It this argument is omitted, then the default printer will be used.

    Thanks both. Yes, the /t worked fine until the last page, which is still open and so the program is. So I'm pretty much where I started.. There must be a way to just terminate an open program or an empty!

    But now if you have the process Id (hwnd), you could use one of your suggest methods (like TerminateProcess(hwnd, 0)), or?

    Honestly, I haven't dived to deep in how to get the hwnd yet. How exactly do I retrieve it from ShellExecute in C++? Do I have to pass a value calling the method or does it return a value without an input parameter? Regarding to MSDN this is a parameter, but the class definition in Ax does not have it.

    I'm a little bit irritated. Tought you use WinAPI::shellExecute(DIRECTORY + "\\" + filename, '', '', "Print"); in AX? And this method returns the hWND

    hwnd = winapi::shellexecute('myprogram');

     However if you use it directly in c++ it's the return value of the shellExecute method too, the first parameter is the hWND of the program which calls the function, this is not an out parameter.

    Hope this clarify a little bit.

    Of cource! This cleared a lot to me! I will look at it. Sorry to irritate you. As you see, I'm kinda new in this game and still has much to learn.

    Thanks a lot and have a nice week end!

    I think you are wrong here. As posted [url=http://dynamics-ax.blogspot.com/2005/12/winapishellexecute-method.html]here[/url] there are only two values which come back from WinAPI::shellExecute:

    0 - Problem

    1 - Launch was ok

    I tested this with opening the internet explorer and i ever got back the value 1 because the IE was opened correctly.

    Best Regards,

    Tobias
