用函数简化你的字符串连接语句
类别: ASP教程
\'你是否非常讨厌 用 & 一大串的连接变量?
\'你是否不得不经常使用""与"""" ?
\'就好像这样:
\'strFilter = strFilter & " and [" & strFldname & "] like """ & strValue & """"
\'
\'strSql ="insert into tblpubStyle (Class,Prop,Value,Type,[Set],memo,flag) values (\'" & _
\' ctl.ControlType & "\',\'" & _
\' prp.Name & "\',\'" & _
\' prp.Value & "\',\'" & _
\' prp.Type & "\', " & _
\' 2 & "," & _
\' "\' \', " & _
\' false ")"
\'
\'strCnn = "Provider=sqloledb;" & _
\' "Data Source=" & strServerName & ";" & _
\' "Initial Catalog=" & strDbname & ";" & _
\' "User Id=" & strUid & ";" & _
\' "Password=" & strPwd & ";"
\'
\'用它,gCombinationString,这个十分简单的函数,让冗长的代码更简洁,增强语句可读性
\'以下是它的使用典型形式:
\'strFilter = gCombinationString( "$1 and [$2] like ""$3""",strFilter,strFldname,strValue)
\'strCnn= gCombinationString("Provider=sqloledb;Data Source=$1;Initial Catalog=$2;User Id=$3;Password=$4;",_
\' strServerName ,strDbname ,strUid, strPwd)
\'参数个数不限,参数类型不限
\' strSql = gCombinationString("insert into tblpubStyle (Class,Prop,Value,Type,[Set],memo,flag) " & _
\' " values (\'$1\',\'$2\',\'$3\',\'$4\',$5,$6)", _
\' ctl.ControlType, prp.Name, prp.Value, prp.Type, 2, False)
\'
Const strCharPre = "$"
Dim varItem As Variant
Dim i As Integer
i = 0
For Each varItem In Para
i = i + 1
strText = VBA.Replace(strText, strCharPre & i, varItem)
strText = VBA.Replace(strText, strCharPre & "", strCharPre)
Next
gCombinationString = strText
End Function
