Visual Basic Specifications, Limitations, and File Formats

This appendix describes the system requirements, limitations on a Visual Basic project, the types of files that may be included in your Visual Basic project, and descriptions of the form (.frm) and project (.vbp) files.

Note   While many of these limitations are described in terms of a specific number, keep in mind that other conditions (such as available memory and system resources) may impose a restriction before the specified limit is reached.
