求救,关于转换金额大写的问题.

以下代码可以转换数字成金额大写,但在转换30.34类似的金额时,只难转换成"叁拾元叁角肆分",而我要转换成"叁拾元零叁角肆分",即元位为"0"时,元和角之间要加"零",我不知道在哪里修改代码,请各位帮忙/代码如下:
-------------------窗体控件布局如下----------------------------------
一个TEXT1(用来输入要转换在金额)
一个TEXT2(用来显示转换后的大写金额)
一个COMMAND1按钮,运行转换命令

--------------------按钮代码------------------
Private Sub Command1_Click()
Text2 = ChMoney(Val(Text1))
End Sub
