前几天收到一份MAIL，说上文《取数据窗口发生变化的一个函数》写的函数中代码没放全，仔细看了一下，是用了另外一些函数，在此表示道歉啦。现在补全那些函数：of_strip() , of_getitem() , of_getstring() , uf_isnull()，不同的函数用不同颜色区分开了。

各位看官有兴趣自己看着改改吧…… :)

/*------------------------------------------------------------------------------

Function: public u_dw.of_Strip

Returns: String

Parameters: value String a_szarg

Description:

-------------------------------------------------*/

Integer nLength, nPos

nLength = Len( a_szArg)

For nPos = 1 To nLength Choose Case Mid( a_szArg, nPos, 1) Case "~t", "~r", "~n", \'"\',":" a_szArg = Replace( a_szArg, nPos, 2, " ") End ChooseNext

Return Trim( a_szArg)

/*------------------------------------------------------------------------------

Function: public u_dw.of_Getitem

Returns: Any

Parameters: value DataStore ads_target value Integer ai_row value Integer ai_col value String as_type

Description:

--------------------------------------------------------------*/

Choose Case Left(as_type,5) Case Left("char(n)",5) return ads_target.GetItemString(ai_row,ai_col) Case Left("date",5) return ads_target.GetItemDate(ai_row,ai_col) Case Left("datetime",5) return ads_target.GetItemDateTime(ai_row,ai_col) Case Left("decimal",5) return ads_target.GetItemDecimal(ai_row,ai_col) Case "int","long",Left("number",5),"real","ulong" return ads_target.GetItemNumber(ai_row,ai_col)End Choose

/*------------------------------------------------------------------------------

Function: public u_dw.of_Getitem

Returns: Any

Parameters: value Integer ai_row value Integer ai_col value String as_type

Description:

---------------------------------------------------------------------*/

Choose Case Left(as_type,5) Case Left("char(n)",5) return this.GetItemString(ai_row,ai_col) Case Left("date",5) return this.GetItemDate(ai_row,ai_col) Case Left("datetime",5) return this.GetItemDateTime(ai_row,ai_col) Case Left("decimal",5) return this.GetItemDecimal(ai_row,ai_col) Case "int","long",Left("number",5),"real","ulong" return this.GetItemNumber(ai_row,ai_col)End Choose

/*------------------------------------------------------------------------------

Function: public u_dw.of_Getstring

Returns: String

Parameters: value Any aa_data value String as_type

Description:

------------------------------------------------------*/

if isNull(aa_data) then return "[Null]"

Choose Case Left(as_type,5) Case Left("char(n)",5) return "\'"+string(aa_data)+"\'" Case Left("date",5),Left("datetime",5),Left("decimal",5),"int","long",Left("number",5),"real","ulong" return string(aa_data)End Choose

/*------------------------------------------------------------------------------

Function: public n_functions.uf_Isnull

Returns: Boolean

Parameters: value String as_str

Description:

---------------------------------------------*/

if isnull(as_str) or trim(as_str) = "" then return trueelse return falseend if另外说一句，如果大家有什么建议或者叫个好，扔个鸡蛋之类的话，请直接在评论上给出吧，因为我的MAIL中经常会自动把邮件转到垃圾信箱中，上面提到的邮件就是这种情形，不好意思啊……还算好，我在删除垃圾邮件之前，看了一眼，呵呵！

总而言之，欢迎大家评论，也让我知道有同志们关注，这样，我会放出更多的东东，小生在此谢过先！
