程序报错
if rb_15.checked =true then
ls_jtdzc =ls_jtdz +rb_15.text
open(w_jtdzz)
close(parent)
end if
if rb_16.checked =true then
ls_jtdzc =ls_jtdz +rb_16.text
open(w_jtdzz)
close(parent)
end if
if rb_17.checked =true then
ls_jtdzc =ls_jtdz +rb_17.text
open(w_jtdzz)
close(parent)
end if
执行后出现报错：application terminated
error:null object reference at line 6 in clicked event of object cb_1 of w_jtdzdzc
[解决办法]
close(parent)
后面要加return !!
[解决办法]
改写下代码：
if rb_15.checked then
ls_jtdzc =ls_jtdz +rb_15.text
end if
if rb_16.checked then
ls_jtdzc =ls_jtdz+rb_16.text
end if
if rb_17.checked then
ls_jtdzc = ls_jtdz +rb_17.text
end if
open(w_jtdzz)
close(parent)
