SYMPTOMS
The User Interface (UI) Toolbox provided in Microsoft Basic Professional Development System (PDS) versions 7.00 and 7.10 incorrectly allows a mouse cursor to choose a menu option from outside the confines of a narrow pull-down menu.



STATUS
Microsoft has confirmed this to be a bug in Microsoft Basic PDS versions 7.00 and 7.10 for MS-DOS. The correction is provided below.



MORE INFORMATION
To correct this problem, the source code of MENU.BAS can be changed to correctly choose items in a narrow pull-down menu. Change the following IF statement found in the SUB MenuDo near the line label &quot;menuDoShowPullDown:&quot;. (When you load MENU.BAS into the QBX.EXE editor, this label is at line number 650, and the IF statement is located at line 660.)

Change the following line LEN(GloTitle(currMenu).text)

to

LEN(RTRIM$(GloTitle(currMenu).text)) in both of the following places: IF GloTitle(currMenu).rColItem - GloTitle(currMenu).lColItem _ < LEN(GloTitle(currMenu).text) THEN GloTitle(currMenu).rColItem = GloTitle(currMenu).lColItem _ + LEN(GloTitle(currMenu).text) END IF NOTE: The underscore characters (_) above indicate line-continuation characters. The block IF statement actually appears as three lines in the original source code of MENU.BAS.

The changed code is as follows: IF GloTitle(currMenu).rColItem - GloTitle(currMenu).lColItem _ < LEN(RTRIM$(GloTitle(currMenu).text)) THEN GloTitle(currMenu).rColItem = GloTitle(currMenu).lColItem _ + LEN(RTRIM$(GloTitle(currMenu).text)    END IF To enable correct handling of narrow pull-down menus, this change should be made and the libraries rebuilt as follows:     BC /X/FS MENU.BAS;

LIB UITB -+MENU;    [NOTE: UITB.LIB is the library that GENERAL.BAS outlines how to build.]

LINK /Q UITB.LIB,UITB.QLB,,QBXQLB.LIB; The correction in this article is the same as for a different symptom described in a separate article, where garbage characters appear after selecting a menu at or to the right of the 64th column.
