The User Interface (UI) Toolbox menu routines, provided with Microsoft Basic Professional Development System (PDS) versions 7.00 and 7.10 for MS-DOS, do not behave correctly when the first menu on the line is disabled. In this case, the menu can still be chosen with the ALT+X key combination.
Microsoft has confirmed this to be a bug in Microsoft Basic PDS versions 7.00 and 7.10 for MS-DOS. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
This article provides an example demonstrating the problem and the correction to MENU.BAS.
Use the following command line to set up QBX for demonstrating the problem:
QBX /L UITBEFR
The following code example disables the first (only) menu, but it can still be selected with the ALT+X keys. To demonstrate the problem, press ALT, which incorrectly highlights the first menu, then press the DOWN ARROW, which incorrectly brings down the menu item (without a proper menu box).
REM $INCLUDE: 'General.bi' REM $INCLUDE: 'Mouse.bi' REM $INCLUDE: 'Menu.bi' COMMON SHARED /uitools/ GloMenu AS MenuMiscType COMMON SHARED /uitools/ GloTitle() AS MenuTitleType COMMON SHARED /uitools/ GloItem() AS MenuItemType DIM GloTitle(MAXMENU) AS MenuTitleType DIM GloItem(MAXMENU, MAXITEM) AS MenuItemType CLS MenuInit MenuSet 1, 0, 0, "Menu Title", 1 '*** Disable main level menu MenuSet 1, 1, 1, "Exit", 1 MenuPreProcess MenuShow MouseShow '*** It should not be possible to select the menu. Pressing '*** ALT highlights the first menu and the arrow brings down '*** other options (with incorrect highlighting). WHILE NOT ((menu = 1) AND (item = 1)) IF MenuInkey$ = "menu" THEN menu = MenuCheck(0) item = MenuCheck(1) END IF WEND
The following IF statement is taken from the end of the MenuDoInit GOSUB routine near the beginning of the MenuDo SUB:
IF lButton THEN mouseMode = TRUE currMenu = 0 currItem = 0 ELSE mouseMode = FALSE currMenu = 1 '****** These lines need currItem = 0 '****** to be changed. GOSUB MenuDoShowTitleAccessKeys END IF
The above IF statement should be replaced with the following IF statement:
IF lButton THEN mouseMode = TRUE currMenu = 0 currItem = 0 ELSE mouseMode = FALSE currMenu = 0 '****** Set defaults to 0 currItem = 0 '****** FOR m=1 TO MAXMENU '****** Search each menu IF GloTitle(m).state = 1 THEN ' check state currMenu=m '****** set menu for 1st state EXIT FOR '****** and exit END IF '****** NEXT '****** last line of changes GOSUB MenuDoShowTitleAccessKeys END IF
This correction should be made and the libraries rebuilt to properly disable a menu item.
