Custom tables in Microsoft Project Add-In

Question

How can I create a custom table in Microsoft Project 2013 by code (C#)?

I'm trying to use MSProject.TaskTables.Add but cannot find the right way to use it. I want to create a new table and set the columns with new names for custom fields.

Thanks in advance

Answer 1

This is one way to do it.

//First create a new table (pj is the current project, MSProject.Project)
var newTable = pj.TaskTables.Add("CustomTableName", MSProject.PjField.pjTaskName, true);
//Get a custom field
MSProject.PjField customField = Application.FieldNameToFieldConstant("CustomFieldName", MSProject.PjFieldType.pjTask);
//Add custom field to your custom table
newTable.TableFields.Add(customField, MSProject.PjAlignment.pjLeft, 10, "CustomTitle", MSProject.PjAlignment.pjCenter);

Answer 2

Thanks Henrik,

I'm getting this error on the last parameter of the second line (MSProject.PjFieldType.pjTask)

An exception of type 'System.Runtime.InteropServices.COMException' occurred in mscorlib.dll but was not handled in user code.

The two things I changed in the code you shared is the object for Application (it's app.Application in my case) and the object for the project which is project instead of pj.

Answer 3

Three things to check:

• Make sure the custom field does exist
• Make sure you write the exact same name of the custom field
• Make sure that the task type you use in the second parameter is the same as the type of the existing custom field

Answer 4

Thanks! That was it. I was using the code with a wrong custom field name.
