web application generator

Commands issued by the application framework use a default timeout of 30 seconds. When necessary, this timeout can be changed to fit application requirements.

Let’s change the default command timeout to 5 minutes.

Start Code On Time web application generator, and click on the project name. Then, click on Develop option. The project will be opened in Visual Studio.

In the Solution Explorer, right-click on ~\App_Code folder and press Add | Add New Item.

Select Class from the list and press Add to create the file. Replace the code with the following:

C#:

using System;
using System.Data.Common;

namespace MyCompany.Data
{
    public partial class Controller
    {
        protected override DbCommand CreateCommand(DataConnection connection)
        {
            DbCommand command = base.CreateCommand(connection);
            command.CommandTimeout = 60 * 5;
            return command;
        }
    }
}

Visual Basic:

Imports Microsoft.VisualBasic
Imports System
Imports System.Data.Common

Namespace MyCompany.Data
    Partial Public Class Controller
        Protected Overrides Function CreateCommand(connection As DataConnection) As DbCommand
            Dim command As DbCommand = MyBase.CreateCommand(connection)
            command.CommandTimeout = 60 * 5
            Return command
        End Function
    End Class
End Namespace

Save the file.

Let’s make sure that the application uses the new command timeout. Place a breakpoint at the last line in the method, and press F5 key to run the web app.

Navigate to any page that has a data view. The application will stop at the breakpoint. Mouse over the command timeout property – the value will now be “300”.

Changing Upload Size Limit

Code On Time automatically handles file uploading and downloading for blob fields. However, ASP.NET limits file upload size to 4 MB by default. When a user attempts to upload a larger file, an error will be thrown.

Let’s change the file size limit in order to allow for larger files to be uploaded.

Start the web application generator. Click on the project name, and select Settings. Press Web Server Configuration.

In the Web.Config modification instructions, insert the following:

SetAttribute: /configuration/system.web/httpRuntime
maxRequestLength: 102400

The maxRequestLength value is the size limit in KB.

Press Finish, and continue to regenerate the web application. When a file larger than 4 MB is uploaded, the upload will no longer throw an error.

Many-To-Many, Project Locations and Groups

Release 8.7.3.0 introduces support for user-defined projct locations and project groups. There is also a set of improvements in many-to-many field handling in forms and inline editing mode. The application framework has been refactored to support addons. For example, release 8.8.0.0 will support Offline Sync Add-On.

Many-to-Many Fields

Inline editing of many-to-many fields is fully supported in the release on mobile and desktop devices.

The application generator now handles the following implementations of many-to-many tables. Tables EmployeeTerritories, EmployeeTerritories2, and EmloyeeTerritories use compound, identity-based, and GUID –based primary keys.

Here is an exampl of Check Box List presentation of the field. The previous screen shot shows “basket” implementation with Auto Complete.

Project Locations and Groups

New Project screen of the app generator has changed and allows specifying an arbitrary project name and project location. Developers can change the display name and group directly on the Namespace & Framework page of the Project Wizard. The start of the app generator will group projects and have them displayed alphabetically within a group. There is also a “top 5” or rather “last changed” projects rendered in a dedicated group at the top of the start page. If the number of projects is less than 10 then “top 5” are not presented.

This is the new version of the New Project screen. Note that if the Visual Studio is installed on your development machine then the Location is automatically set to [User Profile]\Source\Repos folder. The new app will also be configured to use Git for source control.

Cloud On Time

The application framework has been changed to support Cloud Identity, the upcoming membership system based on claims.

If you are using Cloud On Time app for development then make sure to install the latest version. If the app is re-generated then it will become incompatible with the prior releases of Cloud On Time.

Summary of the Release

See release details below:

Many-To-Many fields are now compatible with inline editing.
Many-to-many fields based on tables with identity, guid-based, and comp0und primary keys now work uniformly correctly.
Action with command name Navigate and Result.NavigateUrl will now load in iframe embedded in the virtual Touch UI page if URL starts with “http” . Can force behavior with “_internal:” target, or use "_self" to load current tab, or "_blank" for separate tab.
Touch hyperlinks will now open in internal iframe if target = "_internal".
Touch UI - Read-only checkbox does not overlap the text of the field footer.
Classic UI – Data View property AutoHighlightFirstRow works correctly with hidden child data views.
Classic and Touch UI - Corrected processing of NewValue and OldValue in _findKeyValue method, which was previously causing error when uploading binary data.
Project Wizard now captures Display Name and Group on the "Namespace and Framework" page. The same page also provides a link to open the project location.
The installer now includes folder ~/Library/_Explorer/Images. This folder was missing from the last release.
Cloud Identity request handler is now a part of the framework. Learn about this upcoming feature at http://codeontime.com/roadmap.
Framework now implements support for addons. This feature makes possible for us to introduce the first new product called Offline Sync Add-on. The upcoming Code On Time v9 will be delivered as an add-on.
Important fixes to NewValue and OldValue processing are delivered in this release. Value of the read-only fields is calculated as OldValue if not Modified and as NewValue when Modifed property has been assigned explicitly. Otherwise the OldValue is returned for ReadOnly fields. This addresses numerous issues on the forum in the past week.
