Development and Remediation Guidelines

As §1194.21(f) states, text must be properly exposed to accessibility technology in order for reliable interpretation of the information. The methods for accomplishing this are:

  • Limit use to standard text controls such as the edit control, static text (i.e., text with a window handle), and RichEdit that already use operating system functions to display text and maintain accessibility conformance.
  • Use other controls that are known to only draw text using built-in Windows operating system calls.
  • Manually use calls within the Windows operating system to output text (e.g., TextOut, DrawText). This method provides some compatibility to accessibility technologies that build off-screen models by monitoring screen-drawing operations.
