PowerDesigner技巧集6 ---- 用vbscript获取每个汉字中的首字母

 用vbscript获取每个汉字中的首字母。脚本如下： 

' 获得当前模型
Dim mdl
Set mdl = ActiveModel
If (mdl Is Nothing) Then
	MsgBox "不存在活动模型！ "
Else
	ListObjects(mdl)
End If

' 列出所有的对象
Private Sub ListObjects(e)
	output "实体名：" & e.code
	Dim obj
		For Each obj In e.children
		TableSetNameToCode(obj)
	Next
	' 存在包时，递归包中的实体对象
	Dim f
		For Each f In e.Packages
		ListObjects f
	Next
End Sub

' 转换过程
Private Sub TableSetNameToCode(CurrentObject)
' 当对象是实体对象时执行转换
	if not CurrentObject.Iskindof(cls_Entity) then exit sub
	' 当实体为快捷方式时跳过
	if not CurrentObject.isShortcut then
		output CurrentObject.name
		'T_ 为表头，可根据需要修改。
		' 调用GetPy 子函数来完成实体名的转换
		CurrentObject.code = "T_"&GetPy(CurrentObject.name)
		Dim col ' running column
		dim index1
		index1 = 0
		' 转换每个实体中属性的名称
		for each col in CurrentObject.attributes
			dim s
			' 调用GetPy 子函数来完成属性名的转换
			s = GetPy( col.name)
			col.code = s
		next
	end if
End Sub
' 生成中文串首字母串
function GetPy(strxx)
	dim i
	dim getpy1
	for i=1 to len(strxx)
		getpy1=getpy1 & getpychar(mid(strxx,i,1))
		next
		GetPy = getpy1
End function

' 获取中文单字的首字母
Function getpychar(char)
	'Asc 函数返回与字符串的第一个字母对应的ANSI 字符代码
	' 数字、字母和下划线不予转换，直接返回
	if ((asc(char) >= asc("0") and asc(char) <= asc("9")) or(asc(char) >= asc("A") and asc(char) <= asc("Z")) or (asc(char) >= asc("a") and asc(char) <= asc("z")) or asc(char) = asc("_") ) then
	' 注意：在实际执行脚本时then 必须与if 在同一行
		getpychar = char
	else
		dim tmpp:tmpp=65536+asc(char)
		if(tmpp>=45217 and tmpp <=45252) then
			getpychar= "A"
		elseif(tmpp>=45253 and tmpp <=45760) then
