How To Declare A C# Web User Control But Stop It From Initializing
Apr 2, 2010
I have a C#/ASP.NET .aspx page that declares two controls that each represents the content of one tab. I want a query string argument (e.g., ?tab=1) to determine which of the two controls is activated. My problem is, they both go through the initialization events and populate their child controls, wasting CPU resources and slowing the response time. Is it possible to deactivate them somehow so they don't go through any initialization?
I would like know how to declare a global variable that can be used within a user after the user login and before the user logout across all the possible pages.
I need to develop a web application that will connect to 5 different servers depends on the selection of user on what server they wish to connect and after they select a server and login...I will need to keep track the server name in a variable last until the user logout (user may visit various pages but the server name MUST NOT be changed due to other user login into different server). So how can I do it so that other users may select different servers and will keep the server name for each different users.
Let says:-
User A selects Server A and login and User B selects Server B and login at the same time, so how the global variable can handle the needs for each user (User A & B) with different server select?
Is "Session" the only way to fulfill the above? I think of using Application State but it seems that the value stored will be shared by all users and not for a particular user.
However the code above is giving me a classic Object reference not set to an instance of an object. error. Why? Shouldn't (Session["myIndex"]).Equals(null) capture this particular error?

Im building a web application that charges for access on a per user basis. Ive used standard roles and membership for setting up accounts and logging in. I want to ensure that a client cant use the same user details to login more than once
ie if user abc1 is already logged in, someone else cannot login again using the same credentials
I don't think I understand fully how ASP.NET does inheritance of controls.I have a user control, ucBase, which has an asp.net label in the ascx file. Code behind references the label and it works fine during run time if the control is not a parent for another user parent.
If I have another user control, ucChild, inheriting from ucBase, the label in ucBase's code is always null. ucChild has no controls in its ascx fileThe server controls (like the label) needs to be declared in the ascx file and not created programmatically.What needs to be done for ucBase to see its own controls when it's a parent user control?
I am developing a simple email portal as my college assignment and I refer gmail for various features.Now when we sign into a gmail account and then if we hit the back button of the browser we somehow still remain on the inbox page.In my case after login if I press back button I comeback to the login page.
I have several functions running on a postback that can take a little time to complete.When postback is initiated I show a loading image with this code:
[Code]....
I want to be able to add code to this function so if user tries to leave at this point they are informed the operation is not complete.I found this code:
[Code]....
This works but I only want the code to be active when the loading image is active.I tried the following but it shows the alert message when the page eventually posts back:
Problem Description: A person has to enter all his details and take a photo(While Taking his Snap in our website there will be a Image Component and we have to Initilize the Client System(Any Company Webcam)Webcam and below Image Component there will be a button(Take Snap) When he clicks on it , it should take his snap store it. After He fills all his details when he clicks on Save button, all the details along with that image should be Uploaded to the server.
1) How to Check Whether the Client has Installed any Webcam or Not First. 2) If the Client has Installed any Webcam then Initialize that Webcam When he clicks on Take Picture. 3) Stream that Video that is coming from that Webcam Inside our Image Control in Website. 4) After He Clicks on Save Image button that streaming should stop and still image should be saved. 5) Accessing that Image(Later Converting it to Byte Stream) and uploading Image along with his data to Sql Server.
Problem Statement: I have a details web page which has a unique sesssion ID generated per user. Now if a user does Ctrl + N or File > New Window and opens a new browser instance then the same session ID is genrated and user can update on both the windows differently and this leads to ambigous updates to DB. How can we stop user to open a new window or how can we detect that a new instance of the same session ID has been genrated twice so as to kill both the sessions with a user firiendly message.

I have an asp.net page and I'm trying to add a couple of hidden HTML input controls. I will be submitting this form to another site (PP) so I need the names of the controls to NOT change when rendered. Is there a way to make ASP.NET honor the name property that I set in the code-behind?
As an alternate, I don't need to dynamically create these controls, I can also just assign the value to an existing HTML field but I don't know how to do that with ASP.NET/C#
I have a page with several asp buttons defined on a Master Page. I only wish these buttons to be activated when they are selected by the mouse click. I have one button on the content of the form, that is the button I want to execute if the user hits enter and it is selected or they use the mouse. So in a nutshell. how do I stop the buttons on the master page from executing unless the user mouses them?
