ALERT Function in Basic 7.10 UI Toolbox Destroys TEXT$ (66690)
This article was previously published under Q66690
SYMPTOMS
The ALERT function in the User Interface (UI) Toolbox destroys the
string sent to it in the TEXT$ field of the function call.
WORKAROUND
Any one of the following workarounds will correct the problem but
choices 1 and 2 may be easiest because they don't require recompiling
WINDOW.BAS or building new UI Toolbox support libraries:
- Enclose the TEXT$ parameter in parentheses. For example, the
following statement
Alert(4, a$, 6, 20, 15, 60, "OK", "CANCEL", "")
should be changed to the following:
Alert(4, (a$), 6, 20, 15, 60, "OK", "CANCEL", "")
- Make a copy of the string before calling the ALERT function, as
follows:
temp$ = a$
ALERT(4, a$, 6, 20, 15, 60, "OK", "CANCEL", "")
a$ = temp$
- Modify the ALERT function in WINDOW.BAS as follows:
- Right after the line that says
FUNCTION Alert (style, text$...
put the following statement:
TempText$ = test$
- Right before the END FUNCTION at the bottom of the function,
put the following statement:
test$ = TempText$
You should then make a new Quick library (.QLB) and a new LINK
library (.LIB) that use the new version of ALERT, as shown in the
following:
BC /X/FS GENERAL.BAS;
BC /X/FS WINDOW.BAS;
BC /X/FS MOUSE.BAS;
BC /X/FS MENU.BAS
LIB UITB+GENERAL+WINDOW+MOUSE+MENU+UIASM+QBX.LIB;
LINK /Q UITB.LIB, UITB.QLB, , QBXQLB.LIB;
Invoke QBX.EXE using the new UITB.QLB Quick library, as follows:
STATUS
