When printing characters to the desktop in Microsoft Visual FoxPro 6.0, the following error might occur:
This error does not appear to occur in Visual FoxPro 3.0, 5.0, or 5.0a.
In the example below, removing the @...BOX command or the SAVE SCREEN TO and RESTORE SCREEN FROM commands prevents the error message.
Also, using @...CLEAR instead of simply using CLEAR between the RESTORE SCREEN commands prevents the error message.
This error most often occurs when converting legacy code from FoxPro 2.x for Microsoft Windows or MS-DOS into Visual FoxPro 6.0. Upgrading to Microsoft Visual Studio Service Pack 3 does not fix the problem. In the code example below, the @...BOX, SAVE SCREEN, and RESTORE SCREEN commands act to cause the error. However, printing other characters or using other commands to display data to the desktop might also cause the problem.
Steps to Reproduce Behavior
Create a program containing the following code and execute it:
FOR i=1 TO 10 @1,1 SAY "" SAVE SCREEN && TO scrn2 CLEAR @ 5,30,5,50 BOX RESTORE SCREEN && FROM scrn2 CLEAR RESTORE SCREEN && FROM scrn2 @ 15,1,15,33 BOX ENDFOR
Note that the error mentioned in the "Symptoms" section of this article appears repeatedly.
