SQL Server :: Auto Generate More Complex ID?

Jul 17, 2010 02:11 AM

I really don't know if this Post fit in this Forum section. But here I go. I need some sugestion to develop an ASP.NET code that generate complex IDs / Keys automatically. Let me be more understandable:

I want to create uniquelly IDs with more complex composition (kind of 18958351512783997769711... or crlu0xakecjzlgmjsgnedr55) or something link that (doesn't matter the lenght... those are only examples).

So, I can use that to set COOKIE ID's... PRODUCTS CODE ID's.... CUSTOMER's CART ID's... etc... But it need to generate uniquelly numbers. I don't know if you got my point I hope you did.

Forms Data Controls :: Best Way To Auto-format Auto-generated Grid Columns?

Mar 09, 2010 02:42 PM

I have a "database explorer" page that is desgined to be pointed to an unknown database and allow users to browse the data, so it basically uses the SQL system tables to develop its queries and pull in data to tables using auto-generate columns.The problem that I have is that I would like certain types of columns to have certain formats and I'm wondering the best way to go about it. I could format the column in code in the RowDataBound event I assume, but I'm wondering if there some better standard way to do this? Is there a setting of any kind that I can use? For example I want all of the datetime fields to be formated for short date, like {0:d}, I want decimal fields to have 4 decimal places, etc.

Which Files Are Auto-generated?

Jan 19, 2010 02:18 AM

I know that Visual Studio auto-generates a lot of code when you develop a web application. How do I know which code is auto-generated? I do a lot of code editing and tweaking by hand (Im not a WYSIWYG guy), and I want to make sure I'm not editing something thats going to get over-written later by the auto-generator!

WCF / ASMX :: Auto-generated Values?

Feb 17, 2011 10:56 AM

I'm trying to call a Soap Web Service, and I need to pass an Address Object to the Server. I can pass an existing address.Id to update an existing address, or if I leave the address.Id empty, it should be saved as a new Address. The Problem is that the Id is of long type, and it allways has a value of 0.And this makes problems for the server, because even if the Id=0, the Server Side function will take the Address as Existing one, and it will start to search on the Database for an Address with Id=0. Of course there is no such address, and it throws an error. When I try to call the Web Service with WebService Studio or SoapUI, and I delete the id manually, then It works as expected, as soon as I put <address id="0"> then it returns me an error - Address with Id=0 not found.So the question is, how to change the webservice definitions, or the proxy classes so that it does not generates this id="0" at all?P.S. I cannot change the Server Side method, it would have been the easiest solution, but unfortunatelly is not possible.

MVC :: [AllowHtml] In LINQ To SQL Auto Generated Models?

I used the auto generated models to use my existing SQL server in a new website.in some forms I use rich text editor (CKEditor) so I added [ValidateInput(false)] to those post back actions. but that is a bad solution 'caus I have lost of other from items which needs validation. I came across a potential solution to that using [AllowHtml] which I need to add to the model properties. I tried that:

DataSource Controls :: Linq To Sql Auto Generated Value?

Mar 12, 2010 08:35 PM

In a database table, let's say I have a non-null field named "Description" with a default value of (''). If I drag this table onto the .dbml view in Visual Studio and click on the Description field, the properties will indicate that the Auto Generated Value is set to false, thus ignoring my default value of (''). This is fine, as long as I always explicitly set a value for Description when I perform an insert/update, but I ran into a problem today when I tried to do an insert without specifying a value for Description: Cannot insert NULL value into Description. The default value I set for the field was being ignored. To try and fix this error, I went back into the .dbml and set Auto Generated Value to true, and tried again - no error this time, but the data I tried to insert was ignored, and the default value, (''), was inserted instead. I do not want to explicitly set every field to a default value programmatically when I perform inserts. Is there any other way to resolve this issue other than making the fields nullable?

MVC :: Can't Modify Auto-generated Files With Dataannotations

Feb 21, 2011 06:53 AM

Split off from http://forums.asp.net/t/1654957.aspx/1?Validation+in+MVC+using+JQUERY+OR+JAVASCRIPT. Start new questions in a new thread.

Hey thanks a lot!!!

The following link worked fine http://geekswithblogs.net/stun/archive/2010/02/27/asp.net-mvc-client-side-validation-summary-with-jquery-validation-plugin.aspx

However, I am Having one other problem. There are four solutions in my project. All my controllers and Views are declared in the Presentation solution. There are auto-generated class files in the solution named DomainModel. So, my views inherits these auto-generated files from the DomainModel solution. The problem is that I can't modify these auto-generated files by using Data Annotations in there. Hence, cannot accomplish my validation. I tried by creating partial classes but no result. By creating a class file in my Presentation solution and then binding it with the view the validation works fine. But my views are binded with the class files (auto-generated) from the DomainModel.

Can you/anyone help me work it out so, that validation works with those classes without modifying it.

C# - Adding DataAnnotations To Auto Generated DBML Class?

Feb 17 10 at 14:33

i'm worried about doing this since my changes will be overwritten when the dbml file is auto generated again (as they often are).

i'm thinking of doing a partial class and writing out the same properties to annotate them, but worried that it will complain about duplicates, and the reason i can't even experiment brings me to the second part of my questions...

... that, the expandable arrow on my dbml file listing is missing, right clicking and selecting "View Code" just displays an empty partial class as below...

Partial Class FPDataContext
End Class

I'm using VS2010 RC and am just developing an MVC 2.0 app where i want to be able to use the UI Annotations such as [UIHint("RelativeDateTime")]


here is my VB version edit as an example...

Imports System.ComponentModel.DataAnnotations
<MetadataType(GetType(CommentMetaData))> _
Partial Public Class Comment
End Class
Public Class CommentMetaData
<UIHint("PostedSince")> _
Public Property DateAdded() As DateTime

Specify CLR Namespace Of Auto-generated Web Service Proxy Class?

Sep 10 10 at 14:41

When you add a Web Reference in an ASP.NET project in Visual Studio the web application's root namespace is always added.So, if I add a web reference called MyWebService and the default namespace of the application is MyApplication the namespace of the generated proxy class will be: MyApplication.MyWebService.

However, I want to be able to specify which namespace to use for the generated class (to skip the default namespace and have the namespace be called simply MyWebService).Is using wsdl.exe through the command line the only way of accomplishing this? I don't want to manually edit the generated class (since it can get re-generated).

C# - Fluent NHibernate Many-to-many Mapping With Auto-generated Pk Instead Of Composite Key?

Feb 2 10 at 16:50

I'm working on a RoleProvider in .NET, using Fluent NHibernate to map tables in an Oracle 9.2 database.

The problem is that the many-to-many table connecting users and roles uses a primary key generated from a sequence, as opposed to a composite key. I can't really change this, because I'm writing it to be implemented in a larger existing system.

Here is my UserMap:

public UserMap()

Yet, this is giving me the error:

Type 'FluentNHibernate.Cfg.FluentConfigurationException' in assembly 'FluentNHibernate, Version=, Culture=neutral, PublicKeyToken=8aa435e3cb308880' is not marked as serializable.

Is there a simple fix to allow this HasMayToMany to use my PersistentObjectMap extension? I'm thinking I may have to add a convention for this many-to-many relationship, but I don't know where to start with that, since I've just started using NHibernate and Fluent NHibernate only recently.

EDIT: I think I've found a possible solution here: http://marekblotny.blogspot.com/2009/02/fluent-nhbernate-and-collections.html

I'll try the above method of creating an entity and a class map for the linking table and post my findings.

EDIT 2: I created a linking entity as mentioned in the above blog post and downloaded the newest binaries (
This helped me discover that the issue was with setting lazy load and trying to add roles to the user object in a completely new session.

I modified the code to move OpenSession to the BeginRequest of an HttpModule as described here. After doing this, I changed my data access code from wrapping the open session in a using statement, which closes the session when it is finished, to getting the current session and wrapping only the transaction in a using statement.

This seems to have resolved the bulk of my issue, but I am now getting an error that says "Could not insert collection" into the USR_ROLE table. And I'm wondering if the above code should work with a UserRoleMap described as:

public UserRoleMap()
this.Table("USR_ROLE"); [code]....

Hibernate's documentation for many-to-many relationship suggests creating an object to maintain a one-to-many/many-to-one, as in an ERD. I'm sure this would be much easier with conventional naming standards, but I have to stick with certain abbreviations and odd (and not always properly-implemented) conventions.

MVC :: How To Inject Auto-generated Code Into Views Via Partial Classes

Sep 16, 2010 06:33 AM

I have written a t4 template that basically replaces the work done by StronglyTypedResourceBuilder to give design time access to string resources as properties of classes, one class per resource file. Why? Well I needed to add some customer code that handles string token substitution and a few other customizations. Anyway, the template is working out really well and I may blog on it soon.

In the mean time though, following a common pattern, I have one .resx file for each view, master page, controller, etc. I would really like my t4 template to add a property to each such entity that gives quick access the custom resource class associated with it. For controllers this is easy. T4MVC is ensuring that they are a all declared partial. All I need to do is create the appropriate partial class in my output that declares a readonly property that returns an instance of the appropriate generated resource class.

The Problem:

I would like to do the same thing, inject generated code, into my views. Were this traditional ASP.Net, each .aspx page would have a .aspx.cs page and possibly an .aspx.designer.cs page that are all partial classes extending in the aspx page's class definition. There is no such thing by default in MVC and for good reason. However, I think for my purposes, if there is a way to do this, it would be the way to go.

I could subclass ViewPage and add a generic type parameter and a property that returns the class of that type but that has certain complications. I think adding auto generated code to each view via partial class (that is what partials are for after all) is the way to go.

I have made a basic attempt. I have created a .aspx.cs file for a view and placed a code behind attribute in the page declaration but the class generated from the view seems to reside in a different assembly any my "partial class" ends up as its own class in the same assembly as all my other code.

Prevent HTML Encoding In Auto Generated GridView Columns?

Jan 30 10 at 17:07

I have a GridView bound to a DataTable that I construct. Most columns in the table contain the raw HTML for a hypelinklink, and I would like that HTML to render as a link in the browser, but the GridView is automatically encoding the HTML, so it renders as markup.

How can I avoid this without explicitly adding HyperLink, or any other, columns?

Visual Studio :: How To Change Auto Generated Sql Syntax To Use Quotes Instead Of Brackets

May 28, 2009 06:11 PM

Is there anyway with visual web developer express to change the way the "Configure Datasource Wizard" generates it's sql statement commands to surround the database tables with quotes instead of brackets for odbc connections to non microsoft databases?

For example, I have a database that uses a DataDirect odbc driver and visual web developer seems to connect to it just fine with the connection string but the "Configure Datasource Wizard" generates the following code:

SELECT * FROM [Customers] which breaks my odbc driver instead of using SELECT * FROM "Customers" which works fine with my odbc driver. Most of the other software programs I use generate quotes instead of brackets including Crystal Reports, PrimalScript, PrimalSql, Admin Script Editor and FileMaker Pro Advanced so it would really if we could get visual web developer to generate the quote syntax also.

I have noticed that you can go back in the code later and change the statement, but it sure would be convenient if I could just tweak something so that Visual Studio would generate it correctly with the wizard....

Type Of Data In GridView / Listview Bound - Template And Auto Generated Fields

Aug 18 10 at 11:16

Background: I'm populating lots of asp.net c# GridViews and ListViews from a database and subsequently users may export them to Excel. I want export as native Excel (not html). I can't use office automation, and I'm using JET which works fine. I have no control over users' machines. Question: When doing the export, you have to tell Jet what type each field is, in my case "text" (varchar) or "numeric" (double). The difference is that if you export a numeric column, the users can sum the data in Excel, where as strings are exported with a leading apostrophe and so are not much use in arithmetic.

Currently I parse the first data row of the Grid/ListView, check if each value is numeric or text, and assign a type to the column accordingly. That works, except for when I have something in the first column which looks numeric but in fact is a text string. I don't want to parse every row in order to be sure I have the correct data type as some of these exports are quite large. When I load the Grid/ListView from the database, the database certainly knows what type each field is. So my question is... how do I extract the type of the database item behind a a Grid/ListView item? I could explicitly code it as an attribute on the item, but that's duplicating information I already have, if only I can get to it. I know that where I have a DataTable then I can get the underlying type from that, but mostly I don't have tables handy, just the Grid/ListView. Note that Jet will throw if you try to insert an empty string into a nullable numeric column. The way to do this is to omit that column name from the insert statement, or output a zero.
