不会吧？我做了都可以的啊。不明白你的意思，你自己写的字应该是英文的吧？你建议你用QuickCHM做帮助文件，特别快~！

做好后怎么调用呀？

string condition,condition1,condition2
if trim(ddplb_1.text)="" then
    condition1="3>2"                   //此时无措
    condition2="3>2"
else
    condition1="d_icompany='"+ddplb_1.text+"'"
   condition2 ="d_ocompany='"+ddplb_1.text+"'"     //expression is not valid
end if
condition=condition1+" or "+condition2
MessageBox("Result", condition, Exclamation!)  //显示：
//d_icompany="aa"or d_ocompany="aa"
dw_1.setfilter(condition)
dw_1.filter()
dw_1.retrieve()
MessageBox("Result", condition, Exclamation!)
what's wrong????
