我试图使用一个简单的VBA宏自动化一个基于网络的应用程序。首先,它是为一家公司,我的工作,因此应用程序是在安全的citrix环境。我启动它使用“应用程序启动器”程序。
我尝试我的手使用windows API。一个重要的限制,citrix环境,是我不能安装spy++在它上面。因为公司不允许它。因此,我使用另一个VBA代码,我发现在互联网上实际列出所有的窗口,对象,处理我的机器。这个代码是由马克罗林森写的。
现在,我尝试使用这些有限的信息来自动化GUI访问。
步骤1:使用App Launcher程序启动应用程序。x1c 0d1x
第2步:启动swift登录页面后,我单击HSM框选项。

步骤3:点击HSM框后,我们需要在下面的屏幕上填写用户名,密码和会话PIN。

在这里,我自动执行了步骤2,在该步骤中启动swift登录(手动单击),然后单击HSM盒选项(自动使用VBA)。但在第3步之后,我无法继续前进,因为我无法找到正确的句柄。如前所述,我不能使用spy ++,因为它不允许安装任何第三方软件。因此,我使用另一个VBA代码只是为了列出给定页面上的所有句柄。那么在这种情况下,我如何确定要单击哪个元素呢?
下面是我正在使用的代码。
我的VBA代码自动化步骤2。这是工作正常。

Private Const BM_CLICK As Integer = &HF5
Private Const WM_ACTIVATE As Integer = &H6

Sub ClickPrintButtonWindowsAPI()
    
    Dim hw As Long, mxtextbox As Long, tokenbutton As Long
    Dim pwd As String

    hw = FindWindow(vbNullString, "xxxxx xxx SWIFT Login")
    MsgBox hw
    tokenbutton = FindWindowEx(hw, 0&, "Button", "HSM Box")
    MsgBox tokenbutton
    Call SendMessage(tokenbutton, WM_ACTIVATE, 0, 0)
    Call SendMessage(tokenbutton, BM_CLICK, 0, 0)
    
    subwindow = FindWindowEx(hw, 0&, "ComboBox", vbNullString)
    MsgBox subwindow
    pwdTxtbox = FindWindowEx(subwindow, 0&, "Edit", vbNullString)
    MsgBox pwdTxtbox
    Call SendMessage(pwdTxtbox, WM_ACTIVATE, 0, 0)
    Call SendMessageByString(pwdTxtbox, WM_SETTEXT, 0, "xxxxxxxx")
    
End Sub

VBA代码,我正在使用从马克罗林森列出所有的窗口,句柄,对象等。

下面是运行上述代码后在excel中的输出。

如果你能在这里看到,下面是用户名和密码的句柄名称和值。我怎样才能选择“密码”编辑框?它的值是N/A。

  • 1640324静态用户名
  • 722818编辑不适用
  • 722816静态密码
  • 722814编辑不适用

我需要出去的路。
此外,第一步解析通过应用程序启动程序的树结构也是不可能的,因为间谍++相同的限制。我该怎么办?

x4shl7ld

x4shl7ld1#

谢谢Gserg的提示。我自己也解决了这个问题,通过递归引用。例如,类似下面的内容

firstedit = FindWindowEx(hw, 0&, "Edit", vbNullString) 
secondedit = FindWindowEx(hw, firstedit, "Edit", vbNullString ....

这样我就可以解析同一级别的所有编辑句柄,直到找到正确的句柄。
