Reset Untitled Document Count Example (C#)

For new untitled documents, SOLIDWORKS increments the untitled document count and generates a document name by appending the count to the document type. By default, Part1 is for the first untitled document in a SOLIDWORKS session, Part2 for the next untitled document in that same SOLIDWORKS session, etc.). The untitled document count is automatically reset between SOLIDWORKS sessions.

You can use ISldWorks::ResetUntitledCount to reset the untitled document count within a single SOLIDWORKS session.

The following code example demonstrates how to use ISldWorks::ResetUntitledCount to reset the untitled document count. The code resets the untitled document count at the beginning of the SOLIDWORKS session, creates two untitled documents, maximizes one document, and minimizes the second document.

NOTE: Programs designed to run multiple times in the same SOLIDWORKS session should either assign titles to new documents or reset the untitled document count at the beginning of the SOLIDWORKS session. This ensures that SOLIDWORKS creates predictable names for untitled documents, resulting in predictable outcomes for each invocation of the program.

// Postconditions:
// 1. Creates two new untitled part documents, Part9 and Part10;
//    maximizes Part9 and minimizes Part10.
// 2. Minimize Part9 and maximize Part10.
