Out of Memory opening MPP file

Aspose.Tasks Product Family

I get an out of memory error when opening a Microsoft Project file. Here is how I am opening it in VB.Net:


Using projectStream As FileStream = New FileStream(FileName, FileMode.Open)

Dim existingProject As New Aspose.Tasks.Project(projectStream)

Hi Simon,

Hi Simon,


Thank you for sharing the sample file.

We have tested it with the latest version of the API i.e Aspose.Tasks for .NET 16.11.0 but were not able to face any such exception as OutOfMemory while opening the MPP file. Please try it with the latest version of the API and let us know your feedback.

Sample Code:

Project project = new Project(“142057\PDR13325V1_0001045_OMS Project Plan V0 2 w PCG Tasks.mpp”);

Both of these cause outofmemory error when saving.


’ Save the whole project layout to one file
existingProject.Save(dataDir & Convert.ToString(“PrintProjectPagesToSeparateFiles1_out.png”), saveOptions)

’ Save project layout to separate files
saveOptions.SaveToSeparateFiles = True
existingProject.Save(dataDir & Convert.ToString(“PrintProjectPagesToSeparateFiles2_out.png”), saveOptions)

Hi Simon,


We were able to reproduce the Out of Memory exception while saving the file to PNG. This has been logged as TASKSNET-1740 for further investigation and rectification by our Product team. We’ll update you here once there is some update or a fix version available in this regard. However, we are not able to reproduce the issue with loading the file. Please let us know about your environment details such as OS (32 or 64-bit) and the .NET framework you are using.

Correct, the saving is the issue. We thought it was opening at first.


The issue happens on all customers regardless of OS. 64 Bit Windows 7 .NET framework 4.51.

our application is compiled as 32bit executable due to other libraries we use.

Let me now if you need any other information.
