View 2 RepliesI am having a big problem with the OnTextChanged event of a textbox....
I have tried several different scenerios and just don't seem to be getting it to work right...
I either get a full page postback which is not what I want or get a very peculiar extra textbox added to my page after OnTextChanged is executed...
currently the update panel is working as expected but it inserts an extra textbox into my form "magically"... so strange...the textbox that is added keeps a running history of what is submitted...you can take a look here at the behavior.. it is the email form in the middle of the page
Sample
Here is what I am working with...
[Code]....
and then in the code behind I insert a image to let the user know what is going on..
[Code]....
not sure why an extra textbox is added but everything else seems ok.....
I have tried the following solutions in my ASP.Net(C#) website for which I had previously configured ASP.Net membership module.http://riderdesign.com/articles/Check-username-availability-with-JQuery-and-ASP.NET.aspxhttp://www.ajaxlines.com/ajax/stuff/article/validate_username_using_jquery_ajax_json_and_aspnet_web_method.phpBut when my username textbox losses focus, a following error appears besides my textbox,
[Code]....
Why it is giving this error? Why it is not locating CheckUserName() function that I have added in myPage.aspx.cs file which is it admin's folder?Is it the path issue that I have given in JSON? or its due to something else !!!
Is there any way to check a web service's availability and get an alert whenever it is down?
I am supporting a very critical application and it went down few times because the webservice that it is supposed to be using was not accessible to it. So is there a way in which I could set up some monitoring and poll the web service periodically to check if it is available or not.
If calling the web service is the only way to check, I have a method in the web service which is supposed to return true.. How do I write code(windows app/web app/windows service/anything) so that it calls this method every 5 mins and sends me an email.
What would be the best way to setup the periodic polling, and how do I do it?
have once posted a question but am really not sure how can I go about using AJAX to do it. Some have suggested using jQuery but I'm not sure how to use the jQuery so any suggestions on ASP.NET AJAX? I've already got the codes for the non-AJAX method(using a select statement), but thought that AJAX will be more dynamic.
how can I do it? Here are the codes I used for the non-AJAX method. It works fine, just that I want to use AJAX to do it.[Code]....
I have tried code, but there is error...

View 3 RepliesI wrote a small web service (asmx) to write stuff to a file on the server. It works fine when run in the VS2008 test container. But when I run it under IIS on a remote machine, I get:
System.IO.DirectoryNotFoundException: Could not find a part of the path 'y:grahammiscprops.txt'.
'y' is a mounted drive on both the test and remote machines. The path really does exist. It works on the test machine; not remotely. So:
Is it the fact that 'y' is a mounted drive causing it to fail remotely? or Is it the fact the the path lies outside of the web application directory structure? Is there something I should put in web.config??; or
Is something else the problem? I would have thought that the service running on the server could do anything it wanted! It's not denying me access to the file; it's saying it can't find it??!!

I am looking for a asp.net control that will display a full year in a grid format, with each month as a row and each day in the month as the columns. I have found the following classic ASP script which produces the correct format: http://www.livio.net/code/calendar_36/CalendarTestYearly36.asp?infomode=HELP (see Yearly Calendar)Is anything like this available or is there a way to do this simply without a specific control? I am new to asp.net.
View 2 RepliesI have a web site using master page and login page. I use the MasterPage to check the availability of a session. I'm coding with VB + MS Access database.I believe something is wrong with my master page and I can't figure it out. In the code behind of the MasterPage, I try to check the user session is available. If so, the user is still logged and get access to all the menu. If no session is available, it means the user is logged out and few menu as shown. Here is the code
[Code]....
Please note that my Login.aspx page is also base on the same MasterPage. On the Login.aspx.vb, if the user credential are correct, I did this:
[Code]....
So my logic is this: when the web site is launched MasterPage + Default.aspx load. So Sesson("MyLink") is empty. If the user's credential are correct, I create the session so the it can be available for MasterPage.My default menu isMenuPublic1, MenuPublic2, MenuPublic3When a user logged in, I add to the MenuPublic some reserved menu like below.MenuPublic1, MenuPublic2, MenuPublic3, Menu_Users1, Menu_Users2, Menu_Users3I'm testing my application on two different web hosting server: aspspider.com and somee.com. In the local, everything works perfectly fine.My problem is that on aspspider.com if a user logged in and then click on any MenuPublic, the application does not let him show information from Menu_Users. It's wrongly sending him to the login.aspx but still show his profil on the masterpage and the "welcome username" with beside the Logout link. It seems like the user is still connected but cannot have access to users pages.On the other server (somee.com), even if the user logged in successfully, I still have "welcome guess" with beside the Login link. I also have the user's profil information with all the links. If a user click on any MenuPublic, he can still see all the Menu_Users. But if he clicks on any Menu_Users, the application redirect him to the login.aspx; but still displaying all the information as if he is logged.The package deployed on both server is the same; except the connection string.FYI, I have Global.asa in the package but I don't use it. The web.config has plenty of stuff that came when I first start the project. The only thing I added is the connection string.
Can we Determine the availability of sufficient memory for an operation? if yes, then how can?

View 1 RepliesLets say there's a table Table1 with Primary key as "MainID" and this MainID is being used as a Foreign key in many tables.
Now when I try and delete a record from Table1 who's MainID as foreign key is being used in some child tables, then it throws this exception that "Foreign key conflict n stuff"..
Now I want to design my Delete Strored procedure in such a way that first of all checks ALL the child t ables that have that foreign key column "MainID" and if MainID from Table1 is being used in any of the child tables it should return 0 . Based on this 0 value I want an alert box to show that will say "Still in use or watever" and wont let the user delete that record unless ALL the records in child tables have been deleted that were using that mainID from table1.
I can't use ON DELETE CASCADE. I want the user to delete child table records manually one by one. Only after child table records using the MainID have been deleted that the user can delete record from Table1
