If you want to stick to older technology, you can try WSE (Web Service Enhancement). If I remember correctly, WSE is an add-in which makes SOAP with Attachments (SwA) and Direct Internet Message Encapsulation(DIME) possible on older framework, e.g. .Net 1.1. I, however, do not recommend you to learn phasing out technology. SwA and DIME are now replaced by MTOM.

Strictly speaking, you can't send a file through webservices, you can only send the data in the file.

If you can't assume anything about the content of the file, a byte array is the only way that you can represent the data in the file. You can then convert the bytes to anything you like, for example a Base64 string, but there is no way around the byte array.

I understand that I can send only the data in the file. The question is how to represent this data for transfering through webservices? I want the memory size of my file data to be as small as it can be. For example, if I have an array of bytes, data that passes through webservices should look like this: (array)(byte)1(/byte)(byte)2(/byte)(/array). And it's not very good, because "byte" xml-nodes are repeated too often. And the string representation causes some problems with encodings.

You can turn it into a Base64 string using the Convert.ToBase64String method, and convert it back to a byte array using the Convert.FromBase64String.

The Base64 encoding stores 6 bits in each character, which gives you an overhead of only 33%.

But 2 bits will be lost, won't they? (I am not strong in encodings...)

Of course not, that would be pointless. All the bits are distributed across characters. Three bytes (3*8 bits) are stored in four characters (4*6 bits).

I don't know, may be there is some special stream for sending file data from client to server at once, isn't there?

Meta Tags with Master Pages

Sam Heller30-Aug-07 4:12

30-Aug-07 4:12

I am currently implementing some search engine optimisation accross a large site. The site has a single master page that handles all of the pages. Obviously within each page I can set the pages title using
Master.Page.Title = "The title"

But when it comes to meta tags there are no available easy way's of tackling this, so i had planned to create some. As follows

<!-- BEGIN META TAGS --><br />
<meta id="MetaDescription" runat="server" name="Description" content=""  /><br />
<!-- END META TAGS --><br />

As one tag

and then

Public Property MetaTagsDescription() As String<br />
    Get<br />
        Return MetaDescription.Attributes.Item("content")<br />
    End Get<br />
    Set(ByVal value As String)<br />
        MetaDescription.Attributes.Add("content", value)<br />
    End Set<br />
End Property

to create the get and set properties. My question is this. If I were to add another meta tag and create it's get and set properties how could I got about surrounding these two get and set section into a single meta tag property.

So I could do the following code in the page

Master.MetaTags.Description = "Hobo"<br />
Master.MetaTags.Title= "Hobo"

Any help on this one is much appreciated.

Did you have any previous versions installed? Sounds like a version conflict. Try removing all instances of EL and reinstalling.

javascript runs on the client-side. session is a server-side object.
you can't set javascript variable value to Session Variable in javascript.

You have to pass the javascript variable to the server somehow, and set the session variable there.

You can use AJAX methods, or some postback event to get the variable to the server.

Just off the top of my head...didn't check it but this is the basic concept

DateTime BeginningOfWeek = DateTime.Today;
while( (BeginningOfWeek = BeginningOfWeek.AddDays(-1)) != DayOfWeek.Sunday);
DateTime EndOfWeek = BeginningOfWeek.AddDays(7);
