Last week, Edward Bakker started summarizing some notes and resources on Software Factories, then Jezz Santos added this one on "When would you build one". (Their latest posts have a cyclic dependency, by the way :) I don't know if people (apart from these two guys. They're already into it to their neck :) are more talkative on SF notion lately or my doors of perception are more open to this kind of posts since I'm trying to build one myself, but I started seeing more and more on this subject.

I remember seeing a discussion between Grady (an IBM Fellow, as his blog says) and Greenfield, Cook, Wills and Kent on the UML vs SF kind of debate (and I assure you I didn't have a clue back then how important things they're talking on). Then I interested in code generation. Then I had to use NHibernate for a little project. Then I wanted to generate .hbm.xml documents in VS. Then I thought I prefer attribute decorations rather than XML declarations. Then I found out DSL Tools in this post (Sequence ended in mid 2006. Quite late for me, huh?).

Now, with DSL Tools in hand, I feel like I can take over the world :) Seriously, check the comments for this post. People want tools for their everyday needs. Put some guidance in, integrate with the IDE and they're willing to do the rest. Learning curve might be a little steep but anybody dreaming a tool to generate some code or project instruments or a custom domain intelligent enough to do some repetitive / predefined work may start building it right now or use existing ones, be it DSL Tools, GAT / GAX or one of the available software factories.

It sometimes get frustrating when you debug your project through another instance of Visual Studio, especially if you manipulate the "active" DTE within your debug project. I somehow ended up to the following when getting a reference to DTE:


It worked most of the time, but "not all the time" means you may add a project to the solution where your code resides (the parent VS instance), rather than where the debugging session is. So, after some research, DTE code turned into this:


public static extern int GetRunningObjectTable(int reserved, out IRunningObjectTable prot);


public static extern int CreateBindCtx(int reserved, out IBindCtx ppbc);


public static DTE GetDTE(string processID)


    IRunningObjectTable prot;

    IEnumMoniker pMonkEnum;


    string progID = "!VisualStudio.DTE.8.0:" + processID;


    GetRunningObjectTable(0, out prot);

    prot.EnumRunning(out pMonkEnum);



    IntPtr fetched = IntPtr.Zero;

    IMoniker[] pmon = new IMoniker[1];

    while (pMonkEnum.Next(1, pmon, fetched) == 0)


        IBindCtx pCtx;

        CreateBindCtx(0, out pCtx);

        string str;

        pmon[0].GetDisplayName(pCtx, null, out str);

        if (str == progID)


            object objReturnObject;

            prot.GetObject(pmon[0], out objReturnObject);

            DTE ide = (DTE)objReturnObject;

            return ide;




    return null;

I was trying to solve the Custom Tool property issue with .actiw files in ActiveWriter, as suggested by Bogdan Pietroiu months ago, and spent a clear hour trying to figure how to inject my own registry keys into WiX setup project of DSL Tools. I modified the .vstemplate for .actiw files to include the following:



  <CustomParameter Name="$itemproperties$" Value="CustomTool" />

  <CustomParameter Name="$CustomTool$" Value="ActiveWriterCodeGenerator" />



and thought that the file, when added to the project, will have Custom Tool property already set. I was appearently wrong (documentation says it should work).

Bogdan's suggestion was to have a key named after the file extension under Generators\{Language}, and I manually confirmed that it works great. So, how to automate the process of adding this reg key through the setup? WiX Toolkit documentation shows the way, so I copied Registry.wxs to have my own key registered.

<?xml version="1.0" encoding="utf-8"?>

<Wix xmlns='http://schemas.microsoft.com/wix/2003/01/wi'>

  <Fragment Id="CustomToolFragment">

    <FeatureRef Id="DefaultFeature">

      <ComponentRef Id="_ActiveWriterCTReg" />


    <DirectoryRef Id="TARGETDIR">

      <Component Id="_ActiveWriterCTReg" Guid="{some GUID}">

        <Registry Root='HKLM' Key='Software\Microsoft\VisualStudio\8.0\Generators\{164b10b9-b200-11d0-8c61-00a0c91e29d5}\.actiw' Id='{some GUID}' Type='string' Value='ActiveWriterCodeGenerator' />

        <Registry Root='HKLM' Key='Software\Microsoft\VisualStudio\8.0\Generators\{fae04ec1-301f-11d3-bf4b-00c04f79efbc}\.actiw' Id='{some GUID}' Type='string' Value='ActiveWriterCodeGenerator' />





<Registry> elements define the key to be added, as you may have guessed. Anyway, although I changed the build action on the .wxs and although it seems that Candle and Light picked up the file, the installer didn't add the registry key. So? Orca to the rescue. You should check Component and Registry tables in .msi file to check if your key slipped in, and Orca shows them quite detailed. In my case, though, it shows the absence of my additions.

Long story (not so) short, it seems that I should examine Registry.tt as the first step, but didn't. To include your ComponentRef in DefaultFeature, you should have your Fragment as FragmentRef in Main.wxs . So, you should add each of your custom fragment in the list defined in customFragmentIds in InstallerDefinitions.dslsetup as shown below:

<installerDefinition xmlns="http://schemas.microsoft.com/VisualStudio/2005/DslTools/InstallerDefinitionModel"



I hope this info helps someone.
