I thought this would be simple... Trying to create a login does an ajax check before submit


I have the standard .net login control that is working.  (Still learning .net after 15yrs of classic)

What I want to do is OnButtonClick run a javascript function (to do an ajax call to the db to check if login is valid or not) and if it returns true, then submit the form normally, else don't submit. The piece that I can't figure out, is how to correctly override the default click even to hit my JS routine and then submit the form properly afterwards.

Thanks ahead of time

How to modify the login control



I'd like to record more information than the default control allows as well as perform actions with the input when the form is submitted but I'm having trouble figuring out how.

So firstly, if I want to record the middlename for example, how would I do that, and by default, where would it go if anywhere?
When the form is submitted, I'd like to take specific input, such as just the middlename for example, and write some linq to sql code to specify when and how it's stored.
In what event would I put this code?

Visual Web Developer 2010 Express "Copy Web Site" using different login


I created a site and am trying to grant another pesron access to upload changes to it without giving them my super-user login.

I made a login for her but I can't test whether it works or not because no matter how much I "disconnect" in the Copy Web Site page of VWD 2010, reconnecting to the same site always logs in as my superuser account without prompting me for a login again.

How do I test is the account it set up correctly before having her try to upload to it?    I want to force the login to remote site dialog to pop up again to test her account.

Any ideas?

Login Adpater


I am having problems getting the adpaters to work.  The Whitepaper references a vsi to install but the link to download does not contain the vsi - just source for the CSSFriendly kit.  The kit is missing the css/import.css file also.

Anyway, I fumbled around and was able to get the menu working but I cannot figure out how to specify the css class for the login control.  With the CSSFriendlyAdparters.browser file in my project, I lost all styles and most of the features of the login control.  The menu uses cssselectorclass but I tried that server tag on the <asp:login> and it did not work.  The original cssclass attribute does not seem to do anything either.

Can someone point to some documentation on how to use these tags and integrate with the CSSFriendly.dll adpaters.

Thank you,

Advanced Basics: Revisiting Operator Overloading


On the conference circuit recently, I was speaking about some of my favorite new features in the Microsoft® . NET Framework 2. 0, using the content of three recent columns in this series as fodder. In my talk I sped through generics, operator overloading, and the BackgroundWorker component, all in the space of an hour (for the columns, see Advanced Basics: Being Generic Ain't So Bad, Advanced Basics: Calling All Operators, and Advanced Basics: Doing Async the Easy Way).

Login page for whole site


Hi all,


I've been searching and trying to get this now for hours, so i though i'd come here.

For my website, there will be an admin site. I want to create users in my website database, i have a logins table with a hashed password column. The problem i have is making sure that every request if not already logged in send the user to the login page.


I have a page Login.aspx which i have created, but if i enter http://website/admin/news.aspx it bypasses the login screen and shows the page!!


Does anyone know how i can do this? i have created Login.aspx myself and verified that the username and password enetered are correct.

Customize failure text for login control


Hi all,

I would like to show the failure text in a client-side alert box for login control in c#. Please help me if there is an easy way to convert it from vb.net to c#.net. Thanks a lot!

Protected Sub Login1_LoginError(ByVal sender As Object, ByVal e As System.EventArgs) Handles Login1.LoginError
'Display the failure message in a client-side alert box
ClientScript.RegisterStartupScript(Me.GetType(), "LoginError", _
String.Format("alert('{0}');", Login1.FailureText.Replace("'", "\'")), True)

 End Sub

 Converted, but it doesn't work.

protected void Login1_LoginError(object sender, System.EventArgs e)
    //Display the failure message in a client-side alert box
    ClientScript.RegisterStartupScript(this.GetType(), "LoginError", string.Format("alert('{0}');", Login1.FailureText.Replace("'", "\\'")), true);

Syntax error (missing operator) in query expression

Good Day Gurus!

I have a Excel user application which has a user form (named 'Registo') that displays criteria and an image that has been entered in it's corresponding spreadsheet. This works the way it should.  There's also the ability to search the spreadsheet via a form (by clicking 'Pesquisar' button) this opens a search form. However, I having a bit of a problem with it. When I try to search for something it basically doesn't do anything at all. It just sits there. So I tried to debug it and I think I'm having a problem with either the JET db engine or somethign with teh query or maybe I don't have the correct reference.

I 'borrowed' this Excel application from another forum because it's exactly what I'm looking for! However, I suck at vb.

So I was hoping somebody could take a look at the code and see if I'm missing something?  I'm kinda' desparate to get this working because I'm been trying to figure it out for days and I'm running out of time.  Cry
