How can I hide/change URL in the starting page?

protected void Application_Start(object sender, EventArgs e)
{
// Code that runs on application startup
RegisterRoutes(RouteTable.Routes);
}
static void RegisterRoutes(RouteCollection routes)
{
//routes.MapPageRoute("Uniquename", "Name to shown on Adddress bar AND for redirecting", "Physical Path to the page");
routes.MapPageRoute("Home", "StoreFrontPage", "~/BestSeller.aspx");
routes.MapPageRoute("index", "MainPage", "~/index.aspx");
routes.MapPageRoute("ProductDetails", "DetailOfProduct", "~/ProductDetails.aspx");
}
Above codes helps me change the name of the url when i use "href" or "response.redirect" so when i open the first webpage (the starting page) i could not hide the url.
i do not want users to see the name of the webpage.aspx file.
thanks for any advices/help!

How can i use file upload control in dnn module programming?

I want to use file upload control in dnn module programming.
I know there is DnnFilePicker in dnn, but I want a simple code that each user can upload a file and after that can display, edit and delete it.
There is this code but is not complete.
<%# Register TagPrefix="dnn" Assembly="DotNetNuke.Web" Namespace="DotNetNuke.Web.UI.WebControls" %>
<dnn:DnnFilePicker runat="server" ShowFolders="false" ID="fpUserFiles" FileFilter="pdf,gif,jpg" />
In Page_Load event, set the folder:
// Limit filepath to user's folder
fpUserFiles.FilePath = FolderManager.Instance.GetUserFolder(User).FolderPath;
what should i do?

If you have some sort of Save event on your module view, you simply get the FileId of the file that was selected by the user to save it in the database:
protected void btnSubmit_Click(object sender, EventArgs e)
{
ModelData model = new ModelData {
FileId = fpUserFiles.FileID
};
// TODO: Save your model data
}
In your Page_Load event, you can also load model data (if user is editing an existing model) by setting the fileID on the File Picker. That will pre-select the file in the picker control.
fpUserFiles.FileID = model.FileId
To use the fileId in another module view, you can get it from your model data and get the attributes of the file like this example:
FileInfo fi = (FileInfo)FileManager.Instance.GetFile(model.FileId);
if (fi != null)
{
pic.ImageUrl = "/" + _currentPortal.HomeDirectory + "/" + fi.RelativePath;
}

With this code my problem is resolved.
each user can upload its files in its folder.
protected void Page_Load(object sender, EventArgs e)
{
username = UserController.GetCurrentUserInfo().Username.ToString();
}
protected void Button1_Click1(object sender, System.EventArgs e)
{
var folder = Server.MapPath("~/uploads/Company/" + username);
if (this.FileUpload1.HasFile)
{
Directory.CreateDirectory(folder);
this.FileUpload1.SaveAs(folder + "/" + this.FileUpload1.FileName);
}
}

Correct way of using variables from global.asax

I have a simple global.asax file that runs some code at startup and stores a handle in a variable. I want to access that variable from my other files in the project. Here is my global.asax:
<%# Application Language="C#" %>
<script runat="server">
static JustTesting justTesting;
static public JustTesting JustTesting { get { return justTesting ; } }
void Application_Start(object sender, EventArgs e)
{
//my code here
}
void Application_End(object sender, EventArgs e)
{
// Code that runs on application shutdown
}
void Application_Error(object sender, EventArgs e)
{
// Code that runs when an unhandled error occurs
}
</script>
And when I want to use that variable...
ASP.global_asax.JustTesting
...which works, but I'm sure there must be a more elegant way of calling it instead of having to add ASP.global_asax. all the time.

You can use Application object.
Reading:
var x = Application["x"];
Writing:
Application.Lock();
Application["x"] = "value";
Application.UnLock();
Reference: http://msdn.microsoft.com/en-us/library/94xkskdf(v=vs.90).aspx
You can also create your own class, which should be thread safe.

Not getting value in Viewstate in asp.net using C#?

I am using a asyncfileupload control to upload a file there i am taking the path in a view state like this:
protected void ProcessUpload(object sender, AjaxControlToolkit.AsyncFileUploadEventArgs e)
{
string name = System.IO.Path.GetFileName(e.FileName);
string dir = Server.MapPath("upload_eng/");
string path = Path.Combine(dir, name);
ViewState["path"] = path;
engcertfupld.SaveAs(path);
}
Now when i am trying to save that path in a buttonclick event i am not getting the value of viewstate:
protected void btnUpdate_Click(object sender, EventArgs e)
{
string filepath = ViewState["path"].ToString(); // GETTING NULL in filepath
}
In this filepath i am getting null actually i am getting error NULL REFERENCE EXCEPTION
What can I do now?

Put the Path value in the Session object instead of the ViewState, like this:
protected void ProcessUpload(object sender, AjaxControlToolkit.AsyncFileUploadEventArgs e)
{
....
string path = Path.Combine(dir, name);
Session["path"] = path;
}
Then in the Button Click:
protected void btnUpdate_Click(object sender, EventArgs e)
{
if (Session["path"] != null)
{
string filepath = (string) Session["path"];
}
}

I guess the upload process is not a "real" postback, so the ViewState will not be refreshed client side and won't contain the path upon click on btnUpdate_Click
What you should do is use the OnClientUploadComplete client-side event to retrieve the uploaded file name, and store it in a HiddenField that will be posted on the server on btnUpdate_Click.
Here is a complete example where the uploaded file name is used to display an uploaded image without post-back :

Redirects with Global.asax file in C#

I have added the following code to my Global.asax file:
<%# Application Language="C#" %>
<script runat="server">
protected void Application_BeginRequest(Object sender, EventArgs e)
{
if (ConfigurationManager.AppSettings["IsReviewServer"] == "Yes")
{
if (!Request.IsSecureConnection)
{
string path = string.Format("https{0}", Request.Url.AbsoluteUri.Substring(4));
Response.Redirect(path);
}
}
}
void Application_Start(object sender, EventArgs e)
{
// Code that runs on application startup
}
etc.....
But my BeginRequest function just gets ignored. How do I redirect my entire application from http: to https:?

If you're using a master page or a base class, I would put your logic there. Global events shouldn't be relied upon for logic like this.
Put the logic in Page_Load (or earlier in the lifecycle) of the master page or base class like this:
protected void Page_Load(object sender, EventArgs e)
{
if (ConfigurationManager.AppSettings["IsReviewServer"] == "Yes")
{
if (!Request.IsSecureConnection)
{
string path = string.Format("https{0}", Request.Url.AbsoluteUri.Substring(4));
Response.Redirect(path);
}
}
}
You could do the above at another point in the lifecycle if you wanted too, like PreLoad or PreRender.
Using global events
If you're going to use a global event, I would actually use Application_EndRequest, because it gets called on every request so the application can clean up resources.
