As discussed in our last meeting, web applications can be built to handle both PC browsers and mobile browsers. To do so, the application needs to detect if the browser is a mobile device and redirect the application to a page designed to display UI adequate for the smaller mobile browser. Detecting the browser is done using the following code sample, and it's typically placed in the Page_Load() of the login.aspx or default.aspx
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Try
If Not IsPostBack Then
If Request.Browser.IsMobileDevice = True Then
Response.Redirect("mobile/login.aspx")
End If
End If
Catch ex As Exception
ProcessEx(ex)
End Try
End Sub
I want to know what your ProcessEx() does.
ReplyDeleteProcessEx() is used as a central location for logging all Exceptions. In this particular instance, I simply write the error to a log file and then display the error to the user using a specific .ASPX page. Listed below is the code used for this scenario.
ReplyDeletePublic Shared Sub ProcessEx(ByVal Ex As Exception)
Dim strMsg As String
strMsg = " Error=" & Ex.Message & ControlChars.CrLf
strMsg &= " Method=" & System.Reflection.MethodInfo.GetCurrentMethod.Name & ControlChars.CrLf
strMsg &= " Stack Trace=" & Ex.StackTrace & ControlChars.CrLf
WriteEntry(strMsg)
Dim cls As New clsOpMgmt
cls.ShowError(strMsg)
End Sub
Thanks. Now what does clsOpMgmt do?
ReplyDeleteclsOpMgmt is a class composed of functions used for handling errors. Some of the methods include WriteEntry() which writes to a log file, SendEmail() used for sending automated emails when certain erros occur, and ShowError() which is used to display an error or exception in a user friendly manner.
