Please help with Compiler Error: CS0030

[keithb]

This application works without error in the development environment using
the VS web server. When I publish the site to my IIS 6.0 server, I get this
error at runtime when I open the Change Password page:


Compiler Error Message: CS0030: Cannot convert type
'ASP.admin_changepassword_aspx' to
'System.Web.UI.WebControls.ChangePassword'

Compiler Error Message: CS0030: Cannot convert type
'ASP.admin_changepassword_aspx' to
'System.Web.UI.WebControls.ChangePassword'

Warning: CS0108: 'ASP.admin_changepassword_aspx.ApplicationInstance' hides
inherited member 'ChangePassword.ApplicationInstance'. Use the new keyword
if hiding was intended.



I don't have clue as to the cause. Can someone suggest a way to resolve
this?

Thanks,

Keith

[davefromalbury]

i had a similar problem-try changing the name of the class (where it
says Inherits="some_class" and in the .cs file). Solved it for me

cheers

Hi,

As Dave says above, this problem occurs whenever you have a class name which already exists in the System.Web.UI.WebControls namespace.

So there is plenty of stuff - Login - View - Calendar - any of these cannot be reused.

So, in your example, change the following to get this to work:

1) rename ChangePassword.aspx to ChangePasswordPage.aspx
- if using visual studio, this will also rename the codebehind file.
2) Change the CLASS name in the codebehind also to ChangePasswordPage
3) Change inherits="ChangePassword" to inherits="ChangePasswordPage" in the markup of ChangePassword.aspx

It should now work!
