Hi,
I was trying to send a number from a HTML textbox to add a value to it at the Server, then return it to an ASP textbox.
But I don't know to to pass the value of the HTML textbox to the server.
The 2 Javascript functions are:
//the first function to call the server
function GetNumber() {
UseCallBack();
}
// The function receive the adjusted value from the server and display it into the textbox1
function GetRandomNumberFromServer(arg, context) {
document.forms[0].TextBox1.value = arg;
}
Here are the server side code, written in the .vb file:
Dim _callbackResult As String = Nothing
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim cbReference As String = Page.ClientScript.GetCallbackEventReference(Me, _
"arg", "GetRandomNumberFromServer", "context")
Dim cbScript As String = "function UseCallBack(arg, context) {" & cbReference & "}"
Page.ClientScript.RegisterClientScriptBlock(Me.GetType(), "UseCallBack", cbScript, True)
End Sub
Public Function GetCallbackResult() As String Implements System.Web.UI.ICallbackEventHandler.GetCallbackResult
Return _callbackResult
End Function
Public Sub RaiseCallbackEvent(ByVal eventArgument As String) Implements System.Web.UI.ICallbackEventHandler.RaiseCallbackEvent
_callbackResult =
'equal the value from the HTML textbox + 5
End Sub
Does anyone know where I can add some code to ask to pass the value to the Server?
Thanks,

Hi,
As u show here your callback function can pass Argument to server...
U just simply put it on your UseCallBack Function of javascript...
Use
======================
UseCallBack("Argument u Pass","");
=======================
Now on Server Side U can get this value by RaiseCallBackEvent funtion
Like
=============================
_callbackResult =eventargs.ToString() // It written in C#
=============================
This way u can get Value from javascript to Server

You have to find out where the problem really is. The database field is capable of storing the characters, so it's either when you store the value, when you retrieve the value, or when you display the value that the problem is. Check the actual data before and after each of those stages.

Ok but why when i add the small text as same there isn't any problem ?

It has most likely nothing to do with the size of the text, but rather the contents of the text.

I have developed a web application in which i create some temp files in a temp directory with in appdomain's current directory.
What i want to do is to delete all these files when application starts?
Accordingly i have placed code in Application_Start event of Global.asax file. When i run application through IDE then all temp files get deleted. But when i access the application straight away by typing the url in web browser then it doesn't deletes temp files.
How can i solve this problem?
Thnx in advance

Is it possible to add any code or html in a web page to disable the "Save" ,
"Save As" in the File menu and "Source" option in the view menu of a web
browser. I already have code that disables the right click on a page but I
would also like to disable the View Source and Save/Save As option in the
top menu of the browser. I have tried looking on MSDN's website but I have
not been able to find anything because it is so much info on it.

I have heard of code that does parts of that in some browsers. There is however no code that will do that on all browsers, and there is no code that will cover all the other possibilities to view the source code. You can easily circumvent anything like that by simply using another browser, disable Javascript, get the file from the cache folder, or use some other program to request the page.
What do you have in the source code that you think is worth protecting anyway?

b { font-weight: normal; }

I think you do not need to do that because someone always can get the source as long as the page is accessable from internet.
