显示模式对话框或表单时出错 [英] Error while showing a modal dialog box or form

问题描述

我正在检查数据库中是否存在emailId，如果存在我正在寻找创建确定/取消"确认对话框.如果用户说确定"，我将重定向到其他形式.

I am checking emailId exists in DB, If Exists I am looking to create a Ok/Cancel confirmation dialog. if user say "Ok" I am redirecting to some other form.

我的代码是:

If emailId = True Then
    If MsgBox("Your email address exists in our database. Click OK to update your   Details.", MsgBoxStyle.Information + MsgBoxStyle.OkCancel, Title:="NJ Golf Resort") = MsgBoxResult.Ok Then
        Response.Redirect("~/articles.asp?a=" & a & "&b=" & b )
    End If
End If

对于上面的代码，我遇到了错误:

for above code i m getting error :

显示模式对话框或表单当应用程序未在其中运行时UserInteractive模式无效手术.指定服务通知或DefaultDesktopOnly样式来显示来自服务的通知应用

Showing a modal dialog box or form when the application is not running in UserInteractive mode is not a valid operation. Specify the ServiceNotification or DefaultDesktopOnly style to display a notification from a service application

推荐答案

function redirect(a,b){
      if(confirm('Your email id is in DB')){
          window.location.href='/articles.asp?a='+a+'&b='+b;
       }
} 

在服务器端，调用上述客户端功能为

In serverside call the above client side function as

If emailId = True Then
        this.Page.ClientScript.RegisterStartupScript(this.GetType(), "EmailID", String.Format("redirect({0},{1});", aValue, bValue), true);

    /*For Asp.net AJAX use the following code*/
    ScriptManager.RegisterStartupScript(this.GetType(), "EmailID", String.Format("redirect({0},{1});", aValue, bValue), true); 

如果结束

注意:我已经给出了C#代码.请转换为VB.

Note:I have given the C# code.Translate to VB.
