XAF MOBILE CONTEXT - SUPPORTED in eXpandFramework

XAF offers mobile support long time and the XAF team is constantly adding new features and modules, I guess the out of CTP mode is close enough. So its about time to support the mobile platform from our community project (eXpandFramework).

Long story short: eXpandFramework up to now only recognized two contexts (Win, Web), this will change from v17.1.5.2 where a Mobile context is introduced.

What this means for you?

At the moment there are no new mobile modules released, however you are now able to use eXpandFramework your agnostic modules that reference eXpandFramwork in the mobile platform.

p.s.: All easytests for the Win, Web platform still pass on every release, but at the moment there are no tests for the mobile. but its on schedule.

Looking forward for your feedback at http://www.expandframework.com/forum/

Sending modifer keys to client over RDP

Those of you that use Remote Desktop connection you probably noticed that some key combinations like CTRL+ALT+UpArrow are not passed to the client.

I looked everywhere but I could;t locate a ready solution so in invented one with the use of AutoHotKey.

Install AutoHotKey on both machines and create a Autohotkey script (a file with ahk extension) for the host machine and enter:

*^LAlt::^AppsKey

This will replace all key strokes that use the left alt key with the Control + AppsKey(the one that opens the context menu when right click).

and for the client machine similarly to switch back you need a second script with the following command

*^AppsKey::^LAlt

I am using this workaround for a week now with no issues, hope it helps some of you.

p.s. : if you have a better way, please post in comments

enjoy!

ASP.NET Dashboard Designer - XAF integration

DevExpress released in v15.2.9 an ASP.NET Dashboard Designer (Online Demo). Following eXpandFramework with v15.2.9.2 release an update to the existing integration of the dashboard suite.

Windows

In the existing windows implementation the end user can use the UI to create a DashboardDefinition, assign a few Business object types as datasources and execute the Edit Dashboard action to run the Designer.

Web

Similarly the end user need to perform the same actions to run the ASP.NET dashboard designer and create dashboards over the existing  Business Object domain.

image

As you can see from the images above the eXpandFramework Dashboard module utilize security and syntax highlight editors integrations. The highlight for the win platform is done with the help of DevExpress XtraRichEdit control  and for the web with the help of ACE cloud9 editor.

For those of you interested in the XtraDashboardTester solution you can find and run the related Easytests for the module. Basically the ASP.NET dashboard designer implementation consists of a DashboardDesignerPropertyEditor and a DashboardDesignerController.

As always your feedback/question are welcome in our forums.

How to debug eXpandFramework

In this post I will go through the process of debugging eXpandFramework for each of the distribution channel.
The sources
If you download the sources either from GitHub or our download page or our build server you need to run the buildall64.cmd file located in the root folder. The batch will generate the symbol files (pdb) and will register the assemblies in the GAC. Debugging is enabled by default since symbols and sources are in place.
The Nuget packages
eXpandFramework is distributed through Nuget and since version 14.1.4.8 and with the excellent GitHubLink project provides frictionless debug experience as long as Symbol Server support is enabled under your VS/Options/Debugging settings. The symbols are in the same package as the dll so expect the package size to be at least double in size. We will consider a better implementation if there are requests. GitHubLink patches the symbols so to request the assembly sources from the online GitHub repo so there is not need to have the sources in place.
The Binaries / The Installer
Either way you choose you will end up with a folder containing the eXpandFramework assemblies + the patched symbols. So, debugging is enabled by default and sources will be queried from the online GitHub repo as long as Symbol Server support is enabled under your VS/Options/Debugging settings
PS: In the installer case you can also find the sources under the Sources folder in your installation directory.

Troubleshooting
With debugger attached open your Debug/Windows/Modules list and inspect the messages for each module.

How confident I am with my code?

With smart frameworks like XAF it is inevitable that you will create applications one would except they developed by a whole team and not from just one person. A side effect of rich/large applications is that it is impossible to determine if all parts of the application function unless you have tests.

Enter AutoTest from EasyTest

XAF comes together with EasyTest a functional testing framework. EasyTest has an undocumented command the AutoTest. In short  the AutoTest command will go through all your Navigation Items and for all related views will execute the New action if available and open/close the related detailview.

So, lets talk by example. In eXpandFramework there are 38 Demos with a large number of views, each one demonstrating certain features. By using the AutoTest command we can automate the opening of all views therefore we can expect a code coverage larger than 80%.

Following is the RunEasyTests target used in eXpandFramework build script (Xpand.build).

  <Target Name="RunEasyTests" >
    <MSBuild Projects="@(EasyProjects)" Targets="Build" Properties="Configuration=EasyTest" />
    <CallTarget Targets="EasyTestUpdateDBTimeout" />
    <Delete Files="@EasyTestLogs"/>
    <CreateItem Include="@(EasyTestReqs)" AdditionalMetadata="CopiedToDir=%(EasyTests.RelativeDir);" >
      <Output ItemName="EasyTestReqsToDelete" TaskParameter="Include"/>
    </CreateItem>
    <Copy SourceFiles="@(EasytestReqs)" DestinationFolder="%(EasyTests.RelativeDir)"/>
    <Exec ContinueOnError="true"
          WorkingDirectory="%(EasyTests.RelativeDir)"
          Command='%(EasyTests.RelativeDir)\ProcessAsUser.exe $(TestExecutorName) %(EasyTests.Filename).ets'>
      <Output TaskParameter="ExitCode" PropertyName="ErrorCode"/>
    </Exec>
    <Delete Files="%(EasyTestReqsToDelete.CopiedToDir)%(EasyTestReqsToDelete.Filename)%(EasyTestReqsToDelete.Extension)"/>
    <Error Text="Login failed" Condition="'$(ErrorCode)' == '255'" />
    <CallTarget Targets='PrintEasyTestLogs' ></CallTarget>
  </Target>


Next we will discuss in detail each line of the RunEasyTests target.



<MSBuild Projects="@(EasyProjects)" Targets="Build" Properties="Configuration=EasyTest" />



First we need to build all demos under the EasyTest configuration where the required EasyTest components are functional.



<CallTarget Targets="EasyTestUpdateDBTimeout" />



In the above line we call the EasyTestUpdateDBTimeout target that will run DBUpdater for all demos that have long operations in their ModuleUpdaters. We need to explicitly execute the DBUpdater because there is a threshold in time between each EasyTest command so the Login action may fail if moduleupdater takes more than 25sec to complete. 



<Delete Files="@EasyTestLogs"/>



This command will delete all EasyTest logs to make sure that our build script will not pick up any previous failed tests.



<Copy SourceFiles="@(EasytestReqs)" DestinationFolder="%(EasyTests.RelativeDir)"/>



This will copy a set of required files for EasyTest like the TestExecutor, XpandTestAdapters etc in the same path as the test. In the build server assemblies are not in the GAC so by putting them in the same path we minimize assembly binding errors due to version conflicts.



<Exec ContinueOnError="true"           WorkingDirectory="%(EasyTests.RelativeDir)"           Command='%(EasyTests.RelativeDir)\ProcessAsUser.exe $(TestExecutorName) %(EasyTests.Filename).ets'>





This line executes the TestExecutor for all EasyTests, It uses the ProcessAsUser.exe because the build script is actually executed from our build server service using the System Account which has no windows session therefore useful EasyTest features like screenshots are not available. In general we do not want to mess with the system account in order to make our tests run. So the ProcessAsUser reads a username and password from a registry key and by using an RDC connection (Windows Server) creates a new session and executes the tests there under the specified user security privileges. Finally because we are interested to execute all tests without failing the build to fail we set ContinueOnError to true.



<Delete Files="%(EasyTestReqsToDelete.CopiedToDir)%(EasyTestReqsToDelete.Filename)%(EasyTestReqsToDelete.Extension)"/>



This line will delete all EasyTest required files copied in previous steps



<Error Text="Login failed" Condition="'$(ErrorCode)' == '255'" />



If the ProcessAsUser returns 255 then we fail the build with the Login failed message.

<CallTarget Targets='PrintEasyTestLogs' ></CallTarget>



The PrintEasyTestLogs target will go through all EasyTest logs and for any entry with non passed Result it will fail the build with the related error message from the EasyTest xml log.



  <Target Name="PrintEasyTestLogs" >
    <MSBuild.ExtensionPack.Xml.XmlFile
      TaskAction="ReadElements" File="%(EasyTestLogs.FullPath)" Condition="'@(EasyTestLogs->Count())'!='0'"
      XPath="/Tests/Test[@Result='Warning' or @Result='Failed']" ReadChildrenToMetadata="true">
      <Output TaskParameter="Elements" ItemName="Test"/>
    </MSBuild.ExtensionPack.Xml.XmlFile>
    <Error Text="%0D%0AApplicationName: %(Test.ApplicationName)%0D%0AError: %(Test.Error)" Condition="'@(Test->Count())'!='0'"  ContinueOnError="True"></Error>
  </Target>


A big thanks this time to the AutoTest command that provided 80% code coverage for our community framework. I am sure AutoTest will be extended to provide even smarter automated tested in future versions. If you got into that trouble and have interesting ideas to share or contribute for AutoTestV2 please use our community framework forums.

DX-Nuspec files hosted on GitHub

DevExpress offers a great installer for their components and frameworks. But if you work in a continuous integration environment or have to deal with different versions of the components NuGet packages are the better way to deploy and version-control  dependencies. This project contains .nuspec files for  DevExpress WinForms, Web and XAF assemblies. It is not an official release and it is not supported by DevExpress.

This is the description of the DX-Nuspec files, open sourced from Sergej Derjabkin a casual community contributor! The files are available in https://github.com/derjabkin/DX-Nuspec and of course they will be distributed as a submodule from eXpandFramework v13.2.9.1.

A few more reasons to upgrade to v13.2

13.2 was a great release and many of you already upgraded your applications. For everyone else I am here to help you make that decision sooner and easier, by reminding you what our reviewers had to say, when they upgraded their apps to our latest major release.

These are real world feedback without any kind of interaction from us.

Gustavo Marzioni
Making Business Applications Easier

Gustavo is a veteran programmer (20 years+) with a great presence in our community (most active user in eXpandFramework). He posted a very complete review of all new XAF features and a few other interesting things we released with 13.2 as part of our DXperience subscription. In addition you can find a performance comparison for our new ReportsV2 module.

Mario Blataric
Dungeons of XAF and Magic 13.2

Mario reviews v13.2 and explains how XAF helps him to fight monsters in today’s modern dungeon of dev technologies and platforms. His XAF app has more than 1500 reports so he focuses on the ReportsV2 module.

Martynas Dauciunas
Devexpress 13.2 Review - why bother upgrading ? 

Martynas known from his very useful Excel Import Wizard module wrote an extensive review of all new features and problems encountered when he updated his 12.x ERP/CMMS application to v13.2.

Manuel Grundner
