Hi there,

Did you code your own profile provider? If so, you need to provide more information about it in the <profile> section of web.config:

Code:

<profile enabled="true" defaultProvider="YourProvider">
  <providers>
    <add name="YourProvider"
       type="Your.NameSpace.YourProvider, YourAssembly"
       connectionStringName="YourConn"
       applicationName="AppName"
       description="Your Desc."/>
  </providers>
  <properties>
    ... properties here
  </properties>
</profile>

As you can see, this example also provides info about the name of the provider, namespace, assembly etc...

Cheers,

Imar

yeah i did that i har a vb file like this

Public Class custom_profile
    Inherits ProfileProvider

    Public Overrides Property ApplicationName() As String
        Get

        End Get
        Set(ByVal value As String)

        End Set
    End Property

    Public Overrides Function DeleteInactiveProfiles(ByVal authenticationOption As System.Web.Profile.ProfileAuthenticationOption, ByVal userInactiveSinceDate As Date) As Integer

    End Function

    Public Overloads Overrides Function DeleteProfiles(ByVal usernames() As String) As Integer

    End Function

    Public Overloads Overrides Function DeleteProfiles(ByVal profiles As System.Web.Profile.ProfileInfoCollection) As Integer

    End Function

    Public Overrides Function FindInactiveProfilesByUserName(ByVal authenticationOption As System.Web.Profile.ProfileAuthenticationOption, ByVal usernameToMatch As String, ByVal userInactiveSinceDate As Date, ByVal pageIndex As Integer, ByVal pageSize As Integer, ByRef totalRecords As Integer) As System.Web.Profile.ProfileInfoCollection

    End Function

    Public Overrides Function FindProfilesByUserName(ByVal authenticationOption As System.Web.Profile.ProfileAuthenticationOption, ByVal usernameToMatch As String, ByVal pageIndex As Integer, ByVal pageSize As Integer, ByRef totalRecords As Integer) As System.Web.Profile.ProfileInfoCollection

    End Function

    Public Overrides Function GetAllInactiveProfiles(ByVal authenticationOption As System.Web.Profile.ProfileAuthenticationOption, ByVal userInactiveSinceDate As Date, ByVal pageIndex As Integer, ByVal pageSize As Integer, ByRef totalRecords As Integer) As System.Web.Profile.ProfileInfoCollection

    End Function

    Public Overrides Function GetAllProfiles(ByVal authenticationOption As System.Web.Profile.ProfileAuthenticationOption, ByVal pageIndex As Integer, ByVal pageSize As Integer, ByRef totalRecords As Integer) As System.Web.Profile.ProfileInfoCollection

    End Function

    Public Overrides Function GetNumberOfInactiveProfiles(ByVal authenticationOption As System.Web.Profile.ProfileAuthenticationOption, ByVal userInactiveSinceDate As Date) As Integer

    End Function

    Public Overrides Function GetPropertyValues(ByVal context As System.Configuration.SettingsContext, ByVal collection As System.Configuration.SettingsPropertyCollection) As System.Configuration.SettingsPropertyValueCollecti on
        HttpContext.Current.Response.Write("getpropertyval ue")
        return nothing
    End Function

    Public Overrides Sub SetPropertyValues(ByVal context As System.Configuration.SettingsContext, ByVal collection As System.Configuration.SettingsPropertyValueCollecti on)
        HttpContext.Current.Response.Write("setpropertyval ue")
    End Sub
End Class

i use the HttpContext.Current.Response.Write("setpropertyval ue")
because i'm learning to work with the profile provider and want to know wich function being called and when they are called

i just want to use a ms acces database because the sqlserver is 10 mb on his own and that's why i'm trying to create my default provider

Imar · December 28th, 2006, 06:25 AM

The 10MB you see is just the default for a new SQL Server database created in the App_Data folder of a website. It should be easy to create a blank new one of, say, 1MB, and then configure it for the ASP.NET services.

That said, take a look at this article: http://Imar.Spaanjaars.Com/QuickDocId.aspx?quickdoc=404

It explains how to use an Access database for ASP.NET services....

Hope this helps,

Imar

this is great i will look at it,
only problem is that it only uses c#
i don't know anything about c#
do they have acces providers in vb.net ???

Imar · December 28th, 2006, 07:50 AM

Unfortunately, no, there's only a C# version available.

However, if you only want to *use* the Access version, you don't need to look at the code; all you need to do is compile it.

If you do want to learn from the code, you indeed need to look into C#, although you'll find that a lot of the code is reasonably straight forward and deals a lot with accessing the database...

Cheers,
