extreme basics: browser

Saturday, March 24, 2012

The default page is only showing HTML when copied to Host.

Hi Guys,

I'm working on a little site for a friend (my first!) I've been viewing in browser and everything is going fine, but when I copy the site to the hoster for further development all I'm seeing is html. I'm usingwww.streamline.com as the host, I have all the settings correct (I think), and I have set the webconfig file debug to false.

So, what am I doing wrong.

below is the code from the masterpage. (yes, I'm sure it's messy, but I haven't done the css yet).

Most likely ASP.NET is not setup on the site. Check with the host to be sure the site is on an IIS server running the version of ASP.NET (2.0|3.5) that you have built the site with. Most likely they have not setup ASP.NET on the server.

Thanks. They only open 10am til 4pm gmt so I'll ask them tomorrow.

I don't think you host provides .Net, or if they do .. most probably not 2.0/3.5

Looks like Streamline is a merchant company, not a hosting company.

What is the difference, they offer hosting?

Yes, they charged me an extra 35 quid for the ASP.NET framework, still only 4.5 quid a month though, so not bad.

Ta!

Sorry for my ignorance, but what is a quid in relation to a pound? I know a pound is a little more than a US $ and a pence is similar to our penny.

'Quid' is slang for 1 pound sterling (roughly $2), and a penny is roughly 2 cents.

Everybody says quid, and it's easier on a computer in case the reader's browser doesn't support the Libre 'pound' symbol. For instance, in the british civil service, I believe it is common practice to use a small i instead of the pound symbol.

You learn something every day!

Cool! I was watching the office on BBC America last night and they were talking about Quid. The manager paid the secretary 100 quid to help him in a motivational speaking event.

The dreaded back button

Within an application, is there any way to "tamper" with the history of URLs retained by the browser, so that I can control the URL associated with the back button?

I guess this would entail deleting the last page from the linked list that the browser holds for pages that I do not wish to revisit.

Is this possible?Because of security reasons, you can't get the history from the client.

The first application gives server load error

I'm new to asp.net. Started following a book, I created a FirstApplication and when i try to run it on the browser it gives me the server parse error 'firstapplication.global file not loaded'. Error line 1.
I have not changed anything except for adding a header in the global.aspx file in between the form tags. also the application did'nt create the .vsdisco file. Heard vs2003 does'nt create one. Does it have to do anything with it. Help please!!!!!!!!!!!a header in global.aspx ?
global.aspx to my knowledge isnt used for anything other than writing
applicaiton onstart... on end... session on start and on end etc...
you just write methods for each in global file.
remove the header (cause i dont know y you are adding that header)
open the code file... gloabal.aspx.cs or vb

save the project... build it... and run it...

The image cannot be displayed, because it contains errors.

I have a code in photo.aspx.cs as follows to display image in browser (photo.aspx does not have any space or markup, only @dotnet.itags.org. Page directive):

protected void Page_Load(object sender, EventArgs e)
{
Response.Clear();
Response.ClearContent();
Response.ClearHeaders();
Response.ContentType = "image/bmp";

string employeeID = Request.QueryString["EmployeeID"];
string sqlText = "SELECT Photo FROM Employees WHERE EmployeeID = " + employeeID;
SqlConnection connection = new SqlConnection(ConfigurationManager.ConnectionStrings["NorthwindConnectionString"].ToString());
SqlCommand command = new SqlCommand(sqlText, connection);
connection.Open();
SqlDataReader dr = command.ExecuteReader();
if (dr.Read())
{
Response.BinaryWrite((byte[])dr["Photo"]);
}
connection.Close();
Response.Flush();
Response.Close();
}

Now when I access this page as http://localhost:4538/WebSite12/photo.aspx?EmployeeID=1 in firefox, it gives following error. Can someone help me to sort out this problem please?

The image "http://localhost:4538/WebSite12/photo.aspx?EmployeeID=1" cannot be displayed, because it contains errors.

Hi,

How about this one, which is from http://davidhayden.com/blog/dave/archive/2006/07/25/SavingDisplayingPhotosInSQLServerUsingASPNET.aspx

protectedvoid Page_Init(object sender, EventArgs e){if (Request.QueryString["id"]!=null) {int id;if (Int32.TryParse(Request.QueryString["id"],out id)) { Response.Clear(); Response.ContentType="image/jpeg"; Image image= RetrieveImage(id); image.Save(Response.OutputStream, ImageFormat.Jpeg); } }}private Image RetrieveImage(int photoId){ Image image=null;using (SqlConnection connection=new SqlConnection("...")) {using (SqlCommand command= connection.CreateCommand()) { command.CommandText="SELECT Photo FROM Photos
 WHERE PhotoId = @.PhotoId"; command.Parameters.AddWithValue("@.PhotoId", photoId); connection.Open();byte[] imageData= (byte[])command.ExecuteScalar(); MemoryStream memStream=new MemoryStream(imageData); image= Image.FromStream(memStream); } }return image;}
