ExistControl(Name)

它返回的逻辑值是什么样的呢？

代码如下

If e.Form.ExistControl("Table1")=0 Then
    Dim tbl As WinForm.Table
    tbl = e.Form.CreateTable("Table1", "销售订单", True)
    tbl.SetBounds(6, 330, 663, 250)
    e.Form.Controls("SplitContainer1").Panel2.AddControl(tbl)
    Tables("销售订单").AddNew()
Else
    Tables("销售订单").DataTable.Load(False)
    e.Form.Controls("SplitContainer1").Panel2.removeControl("Table1")
    Dim tbl As WinForm.Table
    tbl = e.Form.CreateTable("Table1", "销售订单", True)
    tbl.SetBounds(6, 330, 663, 250)
    e.Form.Controls("SplitContainer1").Panel2.AddControl(tbl)
    Tables("销售订单").AddNew()
End If
