Question

我想使用带格式字段的Access vba创建一个表。创建表格时如何使用“标准”格式设置货币字段？

<select  ="serv" name="serv">
@foreach($serv as $id=>$name)
<option value="{{$id}}">{{$name}}</option>
@endforeach



{!! Form::select('serv',$serv,null,['id'=>'serv'])

为此，我们使用 DAO 。

这是一个例子。在底部，将 Format 分配给字段：

' Creates the local tables and indexes from scratch if missing.
' Returns True if success, False if not.
