The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Unable to automate MS Project 2007 from C++

Asked by CheapBastard in Automation, Windows MFC Programming, Microsoft Project Project Management Software

Tags: , , , ,

Hi, I am trying to automate MS Project 2007 using C++ (with or without MFC).  I have searched the web and found many examples of how to automate Excel and Word, but none for Project, so I am not sure if I am doing it right.  When I execute the code below, project opens and is visible, but when I query the tasks on the project, I get an exception.  This code doesn't show it, but I have also tried opening an existing file that has tasks and I get the same result.  Please let me know if you see anything wrong:

At the time of running this app, I have MS project open on my desktop with a project that has three tasks in it.

The code below imports the OLB, then tries to access the number of tasks, or it tries to retrieve one of the tasks.  Both operations result in an error.

I posted this on another message board (MSDN) and someone said that this was because I was using __cdecl calling convention and since MS Project automation uses COM, I need to use stdcall.  But I have switched my project to using stdcall and it has made no difference.  Besides, the actual code to call the COM interface is in a file called msprj.tli which is automatically generated by Visual Studio when I import the OLB, so I would think any calling convention requirements would be handled there.

Any ideas?  I am quite stuck on this.  Incidentally, I tried automating Excel and that works just fine, so I don't think it has to do with some problem with office on my machine.

Thanks,

//Here is the code to automate Project:

    MSProject::_IProjectDocPtr project; 
    MSProject::TasksPtr tasks; 
    MSProject::TaskPtr task; 
 
    app->PutVisible(-1);   //prj is already visible, but if I set this to 0, it hides, it so I am successfully talking to prj 
 
    project = app->GetActiveProject(); //project is nonzero after this call 
 
    long x = project->GetNumberOfTasks(); //this returns 3 which is correct!!  
 
    tasks = project->GetTasks(); //tasks is nonzero after this call 
    x = tasks->Count;  //exception is thrown here.  I have also tried tasks->GetCount() and tasks->get_Count(&x)  All of which result in the same error 
 
//Also, this produces an error as well:
//task = tasks->GetItem(0); //Error: Run-Time Check Failure #0 - The value of ESP was not properly saved across a function call
