使用WatiN执行浏览器自动化时出现此错误。
I am using this solution from a previous thread in order to acess the Save As dialog
代码在DownloadIeFile方法的以下行失败。
AutomationElementCollection dialogElements = AutomationElement.FromHandle(windowDialog.Hwnd).FindAll(TreeScope.Children, Condition.TrueCondition);
奇怪的是,如果机器上已经打开IE实例,代码运行正常。我试过仿效:
1]创建临时浏览器的实例
2]创建浏览器对象
用于操纵
3]关闭两个浏览器实例。
这也失败了。
仅供参考我这是我正在使用的代码:
class UpdateDiaryFigures
{
public static void Start()
{
System.Threading.Thread.Sleep(1000);
IE browser = new IE("http://www.example.com");
//browser.Visible = false;
Login(browser);
string test = GetExport(browser, "AgentOpen", "01/10/2014", DateTime.Today.ToString("dd/MM/yyyy"), "Agent Name Ltd");
//browser.Dispose();
}
static string GetExport(IE browser, string exportName, string fromDate, string toDate, string ddlValue)
{
browser.GoTo("http://www.example.com/ExcelExport.aspx");
string open = "";
switch (exportName)
{
case "AgentOpen":
case "AgentClosed":
if (exportName == "AgentClosed") { open = "Yes"; } else { open = "No"; }
browser.TextField(Find.ById("txtAgentFromDate")).Value = fromDate;
browser.TextField(Find.ById("txtAgentToDate")).Value = toDate;
browser.SelectList(Find.ById("cboAgentCleared")).Select(open);
browser.SelectList(Find.ById("cboAgent")).Select(ddlValue);
browser.Image(Find.ById("btnPrintAgentRpt")).Click();
break;
case "AllAgentOpen":
break;
case "AllAgentClosed":
break;
case "CourtOpen":
case "CourtClosed":
break;
}
string filename = @"c:\Downloads\" + exportName
browser.DownloadIeFile(filename);
return filename;
}
static void Login(IE browser)
{
browser.TextField(Find.ByName("ctl00$cphMainContent$txtCompanyID")).Value = "ID";
browser.TextField(Find.ByName("ctl00$cphMainContent$txtUserID")).Value = "user";
browser.TextField(Find.ByName("ctl00$cphMainContent$txtPassword")).Value = "pass";
browser.Button(Find.ByName("ctl00$cphMainContent$btnLogin")).Click();
}
}

即使您只能看到一个IE窗口,也可能会运行多个iexplore.exe进程。例如iexplore.exe和iexplore.exe * 32
