How to store more than 4k bytes of data in SQL CE 4?


I need to store more than 4k of bytes in my SQLCE 4 database. How can I do that with the ASP.NET Web Pages 1.0?

1: The Microsoft.Data provider fails when I try to populate a parameter with more than 4k bytes.
2: Referencing SqlServerCe assembly and using SqlCeConnection/SqlCeCommand/SqlCeParameter throws exception:  SQL Server Compact is not intended for ASP.NET development.

How can I somehow map the generic DbType, which does not have NText as an option, to the ntext column in my database? (SqlCeParameter supports DbSqlType, which has ntext, but see problem #2)

connection string question from a newbie


when publishing  in the webmatrix dialogue it asks for "destination connection string" for my "database.mdf"

I was not sure what it was so I pasted this from my web.config file :

Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\database.mdf;Integrated Security=True;User Instance=True

it all published ok, but wont run, so I guess it has somthing to do with this connection string or some kind of configuration issue.

My question is this, What should go in the field for "Destination connection string"

Security Question Answer Retrieval


I know there is a method built in for retrieving the encrypted password, but how do I retrieve the encrypted security answer?

What I want to do is have a member profile update screen that the end user can update their password and security question and answer. However, when they get to this page, I want to already be showing the security question (the easy part) and its answer (the not so easy part).

I have updated web.config with passwordFormat=Encrypted and have added a machineKey with the generator (forgot the link, but located on eggheadcafe somewhere).

I haven't done ANYTHING yet, since I already have a user store with hashed information. I wanted to get some functionality done before publishing, wiping the store and recreating users (only a couple developers).


Very Basic Question - Error message running first page


Hi Everyone,

I am running Windows 7 and I have gone into Control Panel and activated all of the IIS Functions.

The web application I am running was downloaded from the net (and has worked on other machines previously).  Once I downloaded it, I moved it into C:/inetpub/wwwroot/code/main.asp

I am a bit of a novice at this!  But I am hoping someone can point me in the right direction!


I get the following error when I try and run the web application through IE:

"An error occurred on the server when processing the URL. Please contact the system administrator. If you are the system administrator please click here to find out more about this error."

(When i click the "click here" button it just goes to the IIS site).


Appreciate any help I can get!




C#, LINQ: (List<>) Question???


Hi Everyone,

I have a strange problem:


There is an entity (Table) called "Filters" in my .edmx which has all my tables and stuff in it (to use it for LINQ queries)

I have created a class called "CustomFilters" which inherits "Filters". So now my cutom class has all the properties of the original "Filters" class (table) and 1 more additional property that i wanted which is a List of "CustomFilters":

List<CustomFilters> children = new List<CustomFilters>();

Now i get all my records into:

List<CustomFilters> theOriginalList = new List<CustomFilters>();

NOTE: first all records are tken into a List<Filters> and then these are added into List<CustomFilters> where List<CustomFilters> for children of that record is added, and then children of the child records, and so on......

so now, every record is an instance of CustomFilters which has a property named "children" which is a list again; and each child again has instanaces of "CustomFilters", and each instance again has children...and on and on and on.....

(basiacally its a data source for a treeview in my silverlight control)

every thing is good and working as expected.


linqdatasource parameters question



I'm currently getting to know the linqdatasource control. What would happen if several WHERE parameters are added to the linqdatasource control declaritively in the aspx page but no WHERE clause is defined? 

1. is there any issue with setting up multiple WHERE parameters in the aspx markup for linqdatasource but then deciding which ones actually get used at runtime by setting the actual WHERE clause at run time? Would the unused parameters simply be ignored and cause no issues?

2. when you need to modify WHERE clause or WHERE parameters at runtime do you need to do so in an event handler? such as linqdatasource.selecting?
I see from the above link it is possible, but is that the standard way to handle controlling filtering in code behind for linqdatasource?

2b. if you use an event such as linqdatasource.selecting to add where parameters and/or modify the where clause in code will that also break the builtin sorting and paging support of the linqdatasource with a gridview? 

database interface design question


For handy database interface, is it good to use SqldataSources exclusively intead of EntLib functions?

Store and display Japanese characters



Can anyone tell me the best way of storing Japanese characters through ASP.NET.
I have to put characters into a asp:textbox on one page, which saves it to an Access DB.
On a second page I want to display the content in a asp:label.

Should I store the characters directly to the database or should they be encoded, and
how do I encode the characters? 

In my web.config i have:

<globalization fileEncoding="ISO-2022-JP" requestEncoding="ISO-2022-JP" responseEncoding="ISO-2022-JP" culture="ja-JP" uiCulture="ja-JP" />  

On the display page I have:

<meta HTTP-EQUIV="Content-Type" CONTENT="text/html;CHARSET=shift_jis">
