重新打开MS Project文件 [英] Reopen MS Project file

问题描述

我正在尝试使用以下代码打开ms项目文件。文件的关闭是手动完成的，但我想处理事件以便能够清理清理所需的资源。使用此代码，我第一次尝试打开文件时没有问题。



手动关闭文件并尝试调用OpenReport时遇到问题（重新打开文件）。我收到错误：



无法将Microsoft.Office.Interop.MSProject.ApplicationClass类型的COM对象强制转换为接口类型'' Microsoft.Office.Interop.MSProject._MSProject'。此操作失败，因为由于以下错误，对IID为{00020AFF-0000-0000-C000-000000000046}的接口的COM组件的QueryInterface调用失败：RPC服务器不可用。 （来自HRESULT的异常：0x800706BA）。





当我尝试在不关闭OpenReport的情况下调用OpenReport时会引发不同的错误手动文件。



与基础RCW分离的COM对象无法使用。

I am trying to open an ms project file using the code below. The closing of the file is done manually but I want to handle the event to be able to cleanup the resources needed to be cleanup up. With this code, I have no problem when trying to open the file for the first time.

I am having problems when I manually close the file and try to call OpenReport (to reopen the file). I am getting the error:

Unable to cast COM object of type ''Microsoft.Office.Interop.MSProject.ApplicationClass'' to interface type ''Microsoft.Office.Interop.MSProject._MSProject''. This operation failed because the QueryInterface call on the COM component for the interface with IID ''{00020AFF-0000-0000-C000-000000000046}'' failed due to the following error: The RPC server is unavailable. (Exception from HRESULT: 0x800706BA).


A different error is thrown when I try to call OpenReport without closing the file manually.

COM object that has been separated from its underlying RCW cannot be used.

protected override void OpenReport(string filename)
{
    //projectApp is a Microsoft.Office.Interop.MSProject.ApplicationClass
    projectApp.FileOpenEx(filename, .Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, PjPoolOpen.pjDoNotOpenPool, Type.Missing, Type.Missing, Type.Missing);

    projectApp.Visible = true;
}

提前致谢。

Thanks in advance.
