Save two times crash

Aspose.Tasks Product Family
1

Hello,
I try to open, read and then write a mpp file.
First time, the file is well saved.
But if i try to re-open, re-read and re-write the same .mpp, then it crash, and write a 0 byte file, and the application freezes.
The Aspose Tasks component is the 4.8.0.0 for .net 3.5.

Thanks.

Nicolas.

Here is my code sample :

string projectPath = “c:\temp\project.mpp”;

Project project = null;

ProjectReader mppReader = new ProjectReader();

using (Stream stream = File.OpenRead(projectPath))

{

project = mppReader.Read(stream);

}


ProjectWriter mppWriter = new ProjectWriter();

mppWriter.Write(project, projectPath, TasksDataFormat.MPP);


…


Project project2 = null;

ProjectReader mppReader2 = new ProjectReader();

using (Stream stream2 = File.OpenRead(projectPath))

{

project2 = mppReader2.Read(stream2);

}


ProjectWriter mppWriter2 = new ProjectWriter();

mppWriter2.Write(project2, projectPath, TasksDataFormat.MPP);

Hi Nicolas,


Thank you for using Aspose.Tasks and sorry for the inconvenience you are facing.

Can you please share with us if this happens with a specific MPP file or with any MPP file at your end? I would request you to please share your sample MPP file with us so that we can analyze it and provide further assistance in this regard.

Hello,

Thank you for your reply. The bug happens with any .mpp file. An empty one (freshly created with Microsoft Project) or a project of mine. Here are the two mpp files i use to test. I tried the
project.save method and the writer.write method, same results.
Also, something strange : my Project.mpp is 315 KB before rewrite it, and after the first save, the mpp file is 284 KB… And the bug happens if i try to reopen the 284 KB and re-write into itself.
