Server-side document API
Prepare content before insertion
A detached Selection object can carry text and character formatting before it touches the document. Assigning that prepared object to ServerTextControl.Selection inserts the complete fragment in one operation.
Build a formatted fragment
new Selection / Text / Bold / FontSize / ForeColor
Insert the prepared fragment
ServerTextControl.Selection = preparedSelection
Compare the live pattern
Selection.Text / ServerTextControl.Select / Selection formatting
Render document pages
ServerTextControl.GetPages / Page.GetImage
Technique adapted from Speed Up Document Generation Using Selection Objects.
How the lab executes code
The submitted statements are parsed against a small allowlist that supports live selection operations and named, detached Selection objects. The application does not compile or execute arbitrary CLR code.
Each run returns operation counts, evaluates lesson-specific checks, and renders every document page as SVG through Page.GetImage. The comparison runs both fixed generation patterns repeatedly and reports their measured average on the current server.
