将字符串执行为 属性 以使用 VBS 在 SAP 中设置值

Executing string as property to set values in SAP with VBS

我正在尝试在 SAP GUI 740 中自动执行一系列 属性 set 命令,例如,将字段的 "text" 属性 设置为“12345”如下所示。

If Not IsObject(application) Then
   Set SapGuiAuto  = GetObject("SAPGUI")
   Set application = SapGuiAuto.GetScriptingEngine
End If
If Not IsObject(connection) Then
   Set connection = application.Children(0)
End If
If Not IsObject(session) Then
   Set session    = connection.Children(0)
End If
If IsObject(WScript) Then
   WScript.ConnectObject session,     "on"
   WScript.ConnectObject application, "on"
End If

Function Overall()
    session.findById("wnd[0]/tbar[0]/okcd").text = "12345"
end function

call Overall

效果很好,如下:

Function Overall()
    set control = session.findById("wnd[0]/tbar[0]/okcd")
    control.text = "12345"
end function

还有:

Function Overall()
    set control = session.findById("wnd[0]/tbar[0]/okcd")
    with control
        .text = "12345"
    end with
end function

我需要弄清楚的是如何将 属性 名称和值作为字符串传递给这样的函数,并让它对其进行设置。例如:

Function Desired(Input)
    GUI_ID = Input(0)
    Property_to_change = Input(1)
    Value_to_change = Input(2)
    session.findById(GUI_ID).Property_to_change = Value_to_change
end function

最好的选择似乎是 CallByName,如下所示,但我收到类型不匹配错误。

Function Desired(Input)
    GUI_ID = Input(0)
    Property_to_change = Input(1)
    Value_to_change = Input(2)
    set control = session.findById(GUI_ID)
    CallByName control, Property_to_change, vbSet, Value_to_change
end function

错误:

Microsoft VBScript runtime error: Type mismatch: 'callbyname'

我不知道这是一个简单的语法问题,还是我完全错误地使用了它。我也没有投资于 CallByName,所以如果有更好或更简单的方法,我全力以赴:)

谢谢大家!

在VB脚本中,任务可以按如下方式解决。

例如:

Function Desired(Input_0, Input_1, Input_2)
 GUI_ID = Input_0
 Property_to_change = Input_1
 Value_to_change = Input_2
 set control = session.findById(GUI_ID)
 if Property_to_change = "text" then
  with control
    .text = Value_to_change
  end with
  session.findById("wnd[0]").sendVKey 0
 end if
 if Property_to_change = "setFocus" then
  with control
    .setFocus
  end with
 end if 
 'etc.
end function

If Not IsObject(application) Then
   Set SapGuiAuto  = GetObject("SAPGUI")
   Set application = SapGuiAuto.GetScriptingEngine
End If
If Not IsObject(connection) Then
   Set connection = application.Children(0)
End If
If Not IsObject(session) Then
   Set session    = connection.Children(0)
End If
If IsObject(WScript) Then
   WScript.ConnectObject session,     "on"
   WScript.ConnectObject application, "on"
End If
session.findById("wnd[0]").maximize
call Desired("wnd[0]/tbar[0]/okcd", "text", "12345")
