Retrieve View Info for MS Project Document

This feature allows you to extract detailed information about your MS Project documents using GroupDocs.Viewer.

Step 1: Define Document Path

Specify the location of your MS Project file:

String documentPath = "YOUR_DOCUMENT_DIRECTORY/SAMPLE_MPP";

Step 2: Initialize ViewInfoOptions

ViewInfoOptions viewInfoOptions = ViewInfoOptions.forHtmlView();

Step 3: Retrieve and Output Project Details

Create a Viewer instance, retrieve project details, and print them out:

try (Viewer viewer = new Viewer(documentPath)) {
    ProjectManagementViewInfo info = (ProjectManagementViewInfo) viewer.getViewInfo(viewInfoOptions);

    System.out.println("Document type: " + info.getFileType());
    System.out.println("Pages count: " + info.getPages().size());
    System.out.println("Project start date: " + info.getStartDate());
    System.out.println("Project end date: " + info.getEndDate());
}

Explanation:

getViewInfo(viewInfoOptions): Retrieves view information based on specified options.
The retrieved info object contains properties like file type, page count, and project dates.

Setup for GroupDocs.Viewer Configuration

This section details configuring load options for secure document access.

Step 1: Configure Load Options
