Database Object Selector

Code On Time generator creates database web applications that allow working with all tables and views of your data store. You can limit the number of data objects in your application by excluding those that are not needed in Designer.

The new option allows specifying the scope of your project on Database Connection page of the project wizard.

The following picture shows the project that will include all tables and views.

Click on “Select the database tables and views included in the project” link and database object selector will be presented.

Make your selection and click OK button.

Continue until you reach the summary of data controllers.

If you are testing this feature with Northwind database then you will see a substantially shorter list of database objects included in the project.

Here is the generated ASP.NET 4.0 web application.

Disabling Action on Specific Pages

Q.  How can I disable the New and Delete button on any particular page.

A.

Consider using WhenHRef property of data controller actions. Open the data controller definition in Designer, select Actions tab and activate the action. The action property WhenHRef must represent a valid regular expression.

For example, If you want to use New and Delete actions on pages ~/Pages/Page1.aspx and ~/Pages/Page2.aspx only then the following syntax will work.

Page1|Page2

The assumption is made that the same data controller is present on both pages. You can use any valid regular expression to create a URL test.  The expression will be tested against the URL in the web browser address box. A more precise and complex expression may look as the one below:

/Pages/Page(1|2)\.aspx

If there are other pages that use the same data controller and you want to prevent New and Delete actions from displaying on Page1 and Page2 but have them available on all other pages then we recommend to use an extension to regular expression syntax. Simply put "false:" in front of your expression:

false:Page1|Page2

The prefix in the example above is not a part of regular expression definition and is used to make it easier writing negative regular expression then would have been required otherwise.

Testing and Deploying ASP.NET 4.0 Apps

Code OnTime code generator is not using IIS to run the generated web sites on development machine.

Please install one of the following on your machine to enable testing of ASP.NET 4.0 web sites generated with Code OnTime generator:

Both products will install local Web Developer Server on your machine. There are two Web Developer servers capable of running ASP.NET 3.5, and ASP 4.0. You can find the at "C:\Program Files (x86)\Common Files\microsoft shared\DevServer\10.0".

Our code generator is producing ASP.NET 3.5 web sites for all code generation projects. Web Site Factory code generation project also supports ASP.NET 4.0. The code generator will need WebDev.WebServer40.EXE to run the ASP.NET 4.0 projects.  Otherwise WebDev.WebServer20.exe is required.

If you run the code generator and select the "browse" option next to the name of your project then the appropriate version of the local web server will be started.

If you are generating an ASP.NET 4.0 project and running it under IIS 7 then the following requirements must be met:

You may need to execute "iisreset" from command line to restart the server for  changes to take affect.

Otherwise the application deployment procedure is based on XCOPY model. You will find numerous deployment options described at http://msdn.microsoft.com/en-us/library/ms178610(VS.80).aspx.

We are planning to publish a visual tutorial explaining the deployment process on our YouTube channel. Subscribe to be notified when next batch of tutorials is available.
