Cancelling Open of Project in the Application_newProject event RRS feed

  • Question

  • I am linking MSProject to a Document management system and am working on the file open event. The problem is when there is a later version of the file when opening. What I want to happen is this:

    if (IsNotLatestVersion)
    if(reply == yes)
    //cancel Open and open latest version
    else if (reply == no)
    //Continue opening as normal
    else //Cancel
    //Cancel opening completely, if no project is open show grey background.

    The problem is I cannot cancel the opening, Application.FileClose does nothing if a project is open and throws an exception when there is no other project open (i.e. opening project by clicking on a file)

    Is there any way of cancelling the file open process to allow the other project file to be opened or the opening process to be cancelled.

    Thanks for any answers.

  • Hi Nymain,

    Thanks for posting in the MSDN Forum.

    I never see the Application.FileClose method in MSProject PIA. I think you might say Application.FileCloseEx method. Is it right? Application.FileCloseEx works fine on my side. I would recommend you clarify your MSProject version and Visual Studio version for further research.

    Have a good day,

  • Hi Tom Thanks for your answer.

    My apologies, I do mean FileCloseEx, the reason I cannot use this is it seems to have no effect or throws an error.

    If no documents are open before opening the file I wish to check the version history for (i.e. Double clicking on the file in Explorer rather then a file open, or closing all open projects and using File Open) I get an exception thrown of "The method is not available in this situation".

    I am using Visual Studio 2010 and MSProject 2010.

  • Hello NyMain,

    Try this syntax:



    It closes the Project file, but not MSProject.
