I guess it would be, this is hand type off the top of my head

<asp:Hyperlink runat="server" id="hl_Logout" href="~/Logout.aspx" class="logout" visible="false">Logout
</asp:Hyperlink>

Then in your code behind page on the Page.Load

hl_Logout.visible = False;

If it were my project I would create this as a server control and have it set its own visibility. That way it could be used anywhere and not so tightly coupled to your masterpage.

Failure is not an option; it's the default selection.

Create two different masterpages one for specifically LoginPage without any Menu or Logout Ribbon and other for after Login with all functionality.

Events are not triggered magically. Look at your code, you are causing it somehow.

Hi,

I have an email method written in render event, I dont know but the email is sent multiple times.
Is there any way to avoid page rendering multiple times, or I am using session to control the execution of send email method.

But if the session is there its automatically sending the email. Is there any better solution for this situation.

In render I am capturing the page layout and I am checking for a session, if session is available it has to send the email automatically. But it is sending for multiple times. And there is some email button in its click event too, we have to send the email, but there also it is sending email for multiple times.

Thanks,
Abdul.

If you don't want something to happen then don't code it to happen. You are in complete control of your application, or should be. Look at Page.IsPostback[^]

Dear All,

What is the proper place to set the default culture and uiculture of the entire website?

And the proper place to set the user specific culture and uiculture based on data in de database, ofter the user logs in?

Thanks in advance.

The bad thing is that processes do inherit the language/culture settings from Windows, not from a parent thread. Consequently, you must set that whenever a new thread is started - i.e. at least once for each web page.

Hi,
Please follow any one of the below alternatives.

XML

Alternative 1
In Web.Config file:   <globalization culture="de-AT" uiCulture="de-AT" ….>
Note: If configured here the value would remain same for all the webforms of the project and is not based on clients choice of language.

Alternative 2<a href=""></a>
//Following should be written in Global.asax and this global to all the webforms of the application.
  protected void Application_BeginRequest(object sender, EventArgs e)
  {
        if (Request.Cookies["culture"] == null) return;
        System.Globalization.CultureInfo ci = new System.Globalization.CultureInfo(Request.Cookies["culture"].Value);
        System.Threading.Thread.CurrentThread.CurrentCulture = ci;
        System.Threading.Thread.CurrentThread.CurrentUICulture = ci;

Hi all,
My javascript has a mutidimensional array variable whos content should be filled out by an xmlhttprequest (no ajax preferred) call to a c# web service. The javascript array looks like something below:
var myarray=[[2000,[],[5,6,7],[],[[[3,1,6],0x20,10000,[1]],[[2],0x00,-1,[3]],[[1],0x00,-1,[]],[[1],0x08,500,[2]]]],
[999,[],[],[3],[[[1],0x00,0,[]]]]];

each array element represnts
[type, [values], [sub-types],[next-types],[[item1],[item2],...,[itemn]]]

item=[[indexes],value,attribute,[nextitems]]

How can i convert C# objects into a json response or something like
myarray=myhttpcall()?

Any clues, examples can simplify my work or get me start?

retrieving blob data(image) and display in a picture box

amSherihan13-Apr-12 23:24

13-Apr-12 23:24

my project is based on
asp.net (.net framework 3.5)
language C#
database mysql
the table contains around 50 records of teachers where two field hold blob datatype to store images of teachers(passport size)and signature. I could store the images by the following code

HttpPostedFile postedFile = fluTeacherImage.PostedFile;
Stream stream = postedFile.InputStream;
BinaryReader bReader = new BinaryReader(stream);
byte[] bytesImage = bReader.ReadBytes((int)stream.Length);

it stores the image in the database fine. to that i called my database access class's method. i cant post it here because its too long.
I am using mysql connector 6.4.4

.0

my next task is to retrieve the image from the database and display in a picture box in a webpage which shows the completed profile of a teacher.note that i am just storing the image as blob (not storing its size). I need to get the blob from the db and convert it to byte array or something to display it in the picture box.

please help me as soon ass possible because I couldn't find a suitable code relevant to this
thank you

sir;
in the ordinary case when the image is stored on the server hard disk, the client has the html of

HTML

<image src="request path" />

. But what makes the image to be displayed?

the request(src property) comes back with a response of type image/imagetype and content of the bytes that represent the image.

so, all you have to do is to response the a specific request by setting the content type of the response to image/imagetype and write the bytes in the response.
you can achieve this using an HttpHandler. see this article Httphandlers ASP.NET 2.0[^]
