PRB: Mouse Cursor Disappears in a DO WHILE Loop

ID: Q112399

The information in this article applies to:

• Microsoft FoxPro for MS-DOS, versions 2.0, 2.5, 2.5a, and 2.5b

SYMPTOMS

When FoxPro for MS-DOS executes the INKEY() function with the "M" parameter, the mouse cursor remains visible. However, when FoxPro for MS-DOS executes a DO WHILE loop, the mouse cursor disappears.

STATUS

In FoxPro for MS-DOS, "no mouse" is the indicator that the mouse is busy when running user code. This behavior is by design.

MORE INFORMATION

The following code demonstrates the issue. In FoxPro for MS-DOS, create and execute this program:

   CLEAR
   SET MOUSE ON
   x = SECONDS()
   @10, 0 SAY "Start"
   =INKEY(2,"M")            && Mouse cursor remains visible in ;
                               FoxPro for MS-DOS
   @11, 0 SAY "End"

   DO WHILE SECONDS()-x<=5  && Mouse cursor disappears in ;
                               FoxPro for MS-DOS
   ENDDO
