我在确定模拟测试概念与实际项目中的实施之间的行为差异时遇到了一些困难。请看下面的代码:
测试版本:
Dim tempString As Variant
Dim objCollection As Object
Private Sub TryButton_Click()
marker = 0
Set objShell = CreateObject("Shell.Application")
IE_count = objShell.Windows.Count
For x = 0 To (IE_count - 1)
On Error Resume Next ' sometimes more web pages are counted than are open
my_url = objShell.Windows(x).document.Location
my_title = objShell.Windows(x).document.Title
msgBox my_title
If my_title = "Windowname" Then 'compare to find if the desired web page is already open
Set IE = objShell.Windows(x)
marker = 1
Exit For
Else
End If
Next
End Sub
Implimented版本:
Option Explicit
Private Sub OOAButton_Click()
Dim objCollection As Object
Dim marker As Integer
Dim objShell As Object
Dim IE_count As Integer
Dim X As Integer
Dim my_url As String
Dim my_title As String
marker = 0
Set objShell = CreateObject("Shell.Application")
IE_count = objShell.Windows.Count
For X = 0 To (IE_count - 1)
On Error Resume Next ' sometimes more web pages are counted than are open
my_url = objShell.Windows(X).document.location
my_title = objShell.Windows(X).document.Title
MsgBox my_title
If my_title = "Windowname" Then 'compare to find if the desired web page is already open
Set IE = objShell.Windows(X)
marker = 1
Exit For
Else
End If
Next
End Sub
我的测试版本运行良好,并向我显示我打开的各种IE窗口的名称。这个版本只给我空白字符串。正如您所看到的,唯一的区别是在我的实际应用程序中,我已经声明了显式选项,因此必须声明我的所有变量。字符串是错误的变量类型还是什么?
任何帮助将不胜感激。感谢
