internal means visible in the current project. I thought protected internal means visible only to derived classes within the project.

How can we enforce server to open a confirm pop up window just 4 min before
before expiration of session of a user
,if user select "OK" session time shall increment
Like :
Your session is about to expire
do you want to extend?
OK--||---No
If user select "OK" session time shall increment
if user select "NO" session shall expire
NOTE: POP up should open from server not using from with in the window
thanks

Doesn't the session time out based on inactivity ? So as soon as the server does something, the session timeout is reset. But, your server cannot send anything to the client, the client has to request it. An obvious way is to have a timeout in the page that brings up a popup, clicking yes does a postback, thus persisting the session.

hi i am rightnow building a chat application using asp.net 2.0and i am having this problem When a user sends a request using chat application to another user how will the server sends the response back to the other client that another user wants to start a chat session or wants to start a private chat or is inviting him to join a different room by opening a server enforced information pop up window

Not much idea, but a wild guess. You need to use XML file for communication. Both users should listen to same XML file frequently. Server can put popup command in this file. If client is getting that popup command from XML file, it should popup a new window. I hope you can expand this idea to a working model

You can't send the client anything, the client has to request it, so you need to either have a page that constantly refreshes itself, or a page that makes constant AJAX calls.

The first step when your code is this messy, is to break it down into many smaller pieces of code, so you can work out which one has the problem.

Christian was right.
That method name is OOP ( Object Oriented Programming ).
|
|
|
|
|
I don't think OOP is the point here, he doesn't need an object, just better structured procedural code

Dear All,
I am using asp.net2.0, C#, sql2005 using Visual studio 2005
Let Me explain the scenario I have checkboxlist containg 15 field. Based on no of checked field . I created dropdownlistbox and label dynamically through loop and assign id as dropdownlist + no of iteration. Now my question is how I access these control as when I am accessing one of the control I am getting nullobjectreference error stating “Object reference not set to an instance of an object.”I created control as
Foreach(listitem)
{
//…….
Label label = new Label();
DropDownList dropdownlist = new DropDownList();
//assinging id
label.ID = "label" + i.ToString() ;
dropdownlist.ID = "dropdownlist" + i.ToString() ;
}
And I am accessing it through
cmd.Parameters.Add("@para1", SqlDbType.VarChar).Value = Page.FindControl("label1").ToString() ;
cmd.Parameters.Add("@value1", SqlDbType.VarChar).Value = Page.FindControl("dropdownlist1").ToString();
and my second question is how do i access selected value in dropdownlist1(dynamically created control)
Please guide me
Thanks

Your main problem is that if you don't add your controls bfore the page load event, viewstate will not be restored and so you don't be able to get the selected values as tehy won't be set in the code behind for you.

YES, see Submit1 is empty and you cannot convert "" into a boolean.
