Hi hk:

Thanks for your reply in quick way.

i already create my membership project in the same solution of website. two class under the membership project have been setup, which i named for IV_membershipProvider.cs(replace aspnetmembershipProvider.vb) and IV_securitymembershipProvider.cs(replace aspnetsqlmembershipProvider.vb). both of them are empty class with only default outline. i add two references in the Reference folder of membership project(dotnetnuke.dll and notnetnuke.membership.dataprovider.dll) the same manipulation in website \bin folder should be (1.remove the dotnetnuke.provider.aspnetprovider.dll.   2. add the project to it) i also config the web.config in website as guildline from your <implementing membership and role providers in dotnetnuke> tutorial. but when i set my project as startup point to build , the page in totally blank. when i do the same thing in my website, also the same page occur as well , which replace the original page(notnetnuke default page).

i don't know what's the problem. any suggestion will be appreciated

thanks again

hi hk:

i will answer your confusion in seperate step.

1.  Does the project build without compilation errors?

    yes, i can build my project on successful way

2. When you run the site can you get to the login control(page)?

   if i didn't add my project to the same solution of website and make the change to the bin folder, in which i just remove and add some references, i can logon the default dnn page, all of the function work well including login page. after my modification on above part, i can build my website without any error message,but the default dnn page become a blank page without anything display properly.

3. Can you set a breakpoint on ValidateUser() method in your class to verify that you have your project configured correctly and step through that code when you run the site?

   yes, when i only debug the method validateUser(), which located in AspNetMembershipProvider.vb, can run without error. because i think it's a default method existed in ASpNetMemebershipProvider folder in source file of dnn.

my puzzle is that i build my own MembershipProvider that mainly has the function to authenticate the user from my own database and add or delete user to my personal database rather than default dnn aspnet_* table,which is provided by aspnetmembshipprovider. if i only create a folder named such as IV_Membership Provider which contained only the files of aspnetmembershipprovider.vb and aspnetsqlmembershipprovider.vb without any change to the code in the sub-folder(MembershipProvider)of source folder.  does it work well?

i think at least i should change somethings in original aspnetmembershipprovider.vb such as the namespace to my own project(Company.Security.Membership)and change something in the method, because my own data table of user don't have the same attributes like the aspnet_user.

does it sound wrong or on the reverse way to my destination?

thinks your help !!! 

hi hk:

first of all, thanks for your reply.

i still get confused of the configuration of  web.config file. my project will be in the situation as i described below:

1. i created the project called"IVMembershipProvider" within the the same "solution" of the dnn website.

2.under the project, i directly create three .cs file(IVMembershipProvider.cs, IVMembershipDataProvider. cs, IVRoleProvider.cs) which replace the default provider defined in dnn provider(AspNetMembershipProvider.vb,  AspNetSqlMembershipProvider.vb and DNNRoleProvider.vb) respectively.

3. I already write some necessary methods (override) to execute my function based on my customer membership provider. they can work well as i expected.

4. in the web.config file under the dnn website, i already modify some configure like:

a.

<

members defaultProvider="IVMembershipProvider">providers>clear/>add name="IVMembershipProvider" type="IVMembershipProvider.IVMembershipProvider, IVMembershipProvider.Provider.IVMembershipProvider" providerPath="~\Providers\MembershipProviders\IVMembershipProvider\"/>providers>members>

<

<

<

</

</

b.  c. above two points are the all place i made the modification to original web.config file 

<

roles defaultProvider="IVMembershipProvider">providers>clear/>add name="IVMembershipProvider" type="IVMembershipProvider.IVMembershipProvider, IVMembershipProvider.Provider.IVRoleProvider" providerPath="~\Providers\MembershipProviders\IVMembershipProvider\"/>providers>roles>

<

<

<

</

</

when i only run the project(set as startup project) the debug will be successful, then a blank page will be launched at the end.

when i run the website (set as the startup project) the debug also out of error. but the published page has error message like:

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

 i think there are should be something wrong in the web.config file. but i have no idea about it, could you give some suggestion, i will appreciate any advise

Thanks

Roger,

I opened the project that you sent and I have some concerns listed below:

1. The project appears to be a c# library that contains both .cs and .vb files. A suggestion here, convert all your files to one language (per project).

2. The file AccessMembershipProvider currently does not compile as the functions and private data members are defined outside the Class definition.

3. I noticed that there is a login.aspx page in your project. I'm guessing you trying to test something with this? As if you implement your new provider correctly you would not need (or probably want) to replace the default DNN control.

4. The entries that I saw in the web.conf were in your project (.dll). These should be in the web.config of the DNN site that you are developing with.

I really want to help you here but I'm still not clear as to your intent here. Let me give you a scenario in which you could/should replace the membership provider (or any other providers for that matter).

You are entertaining the idea of using DNN for a project. You currently have a user base in another data store (Oracle, Access or an existing SQL server db). In this other store you have user related information i.e. email, passwords and so on. You can replace the ASPNetMembershipProvider class with your own. The end goal here is to “swap” out the provider for your own. DNN is none the wiser to this (or shouldn’t be). The login form remains “AS IS”. The difference is that your provider class has logic in it to perform all membership related functions i.e. ValidateUser().

An example of where you would find the file that you are replacing is here: C:\Inetpub\wwwroot\DotNetNuke\Library\Providers\MembershipProviders\AspNetMembershipProvider\AspNetMembershipProvider.vb.

I would suggest to start a new project and a new DNN install (4.4.1 as I know that later versions have changed). Take the above file and begin replacing the code to go to your Access DB or whatever. One by one replacing the logic until all calls to read/write to the default ASPNET_* tables are gone. Remember, you still have to make the calls to DNN specific tables as you can’t escape those (yet).

Hope this helps,

Regards,

hk

Same problem here. Is there any chance that you create some kind of tutorial with images and everything to do this custom membershp provider stuff? I know that this is to much for me to ask but it would be really useful.

Thanks
