F11 and F12 Keys Do Not Function in MS-DOS Applications Under NTVDMID: Q189579
|
The F11 and F12 function keys do not work or generate extended characters in MS-DOS applications running under Windows NT.
A program compiled or built using the 32-bit compiler is able to read all
the function keys and to return the right values of the scan codes. When
compiled or built using the 16-bit compiler, the same program returns the
right values for the function keys F1 through F10, but does not return
anything for F11 and F12.
To resolve this problem, obtain the latest service pack for Windows NT 4.0 or Windows NT Server 4.0, Terminal Server Edition. For additional information, please see the following article in the
