Well, one would think. That's what I cannot figure out. The bit that it is failing has had zero changes. There have been no changes to the AppCode folder. There have been changes elsewhere, but it builds and debugs fine, but if I try and publish it then it doesn't work.

This is really strange.

ok back up your App_Code and delete everything there. Build your Project , you will obviously get Errors and copy back the backup contents. Don't copy the folder copy only the contents and built it again and see if this line appears again

I've not tried that yet - I will add it to the list of things to try. I'm currently seeing what it does if I build it in Debug mode (seeing as it seemed to think already it was in debug mode, when I thought I'd set it to release)

That used to happen when the root folder of the website was '/' (rather than the default website name). Try changing the root folder (properties on web site project) and see if it works. If that's the problem, there was probably a hotfix or something for it (?)

I suggest you try this: http://www.integrationpractices.com/post/2010/02/17/Publication-(web)-Object-reference-not-set-to-an-instance-of-an-object.aspx

It perfectly worked for me.

problem with sending emails through website

Hi,

I am making a form in asp.net 3.5 which will send an email to the recipient

Initially I was using system.web.mail

as it is obvious whenever you send an email to some recipient a display name appears instead

of the email id of the sender

consider:

mail_sender=mail@gmail.com

display_name="my name"

in my case instead of the display_name "mail" the initial portion of the sender's email id is coming

but it is desired that "my name" should appear in the recipient's inbox.

due to this I had to switch to system.net.mail

but there also same problem occurs.

I have tried googling on this issue too, but still no help.

Any help shall be appreciated !

Thanks
Shankbond

Have you read the documentation ? Why is the login control on your master page at all ?

CG is right, make a separate page for Login Control and definitely read documentation. Smile | :)

OK - so, you hide it by setting it's visibility. I'm not sure what the issue is.

Use .Master property. You can get MasterPage from this property and then use FindControl() method to cast Login View. Then you can make the control invisible.

Use Authentication Section in Web.Config. User will only be able to access menu.aspx if he/she is logged in.

Use LoginStatus control, it shows a link which displays "Login" if user is not loggedin and "Logout" if user is loggedin. If used click on "Logout" he will be logged out.

I am not clear, what you want here.

After successful login, make it invisible and make it visible after logout.

By changing your code so that it checks every year and not just the current year.

Did you really expect a detailed answer on how to fix code you didn't bother to show us ?
