计算机字符连接函数,用函数简化你的字符串连接语句

'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
