.NET Forum / Visual Studio.NET / Extensibility / April 2006Data sources in miscellaneous project system
Hello, Can the Data Sources window be used with the 'miscellaneous' project system? I am rehosting a modified windows form designer so that it is registered with the miscellaneous project system; that is, I have created an VS editor with a user control that hosts the Windows Form design surface and integrates with the Visual Studio toolbox. I am creating several custom controls for use with my designer and wrapping some existing controls, such as the DataGridView control. The DataGridView control has a DataSource property. Normally, in a vanilla C# Windows Application project system, when I use the DataGridView control, I can choose to add a new data source. However, in the case of my custom editor in the miscellaneous project system, when I choose to select a Datasource from the property grid, there is no facility to add a new data source. Likewise, if I use a BindingSource component in this environment, the DataSource property doesn't give me the ability to add a datasource. So my question is, is it possible to use the Data Source Window and thus controls like DataGridView and BindingSource from a miscellaneous project system? What about through a custom project system, other than the miscellaneous project or is this ablility restricted to the C#, VB .NET and other MS project systems? Thanks, Notre Hi Notre, This is a quick note to let you know that I am performing research on this issue and will get back to you as soon as possible. I appreciate your patience. Thanks for your understanding.

Hi Yanhong Huang, Yes, I am still monitoring the thread and would like to know more. Please contact your support team. Thanks, Notre Hi Notre, so it looks like the data source window tries to get the active project by checking out the property on the hierarchy i.e. hierarchy.Getproperty(VSITEMID_ROOT, VSHPROPID_ExtObject, out o EnvDTE.Project project - o as Project You can try a simple macro that gets the project object for the solution to see if it works for you. The data source tool window also checks if it is not a web project and if project.CodeModel is non-null. You can use a quick macro to check for the codemodel property via looking at the properties of your project object where p = DTE.Solution.Projects.Item(1). Look at the locals window to see if your particular project implements a codemodel. After those checks, they iterate through each of the projectitems with a xsd extension. For each schema projectitem, they get the filecodemodel and iterate through the codeelements. There might be some other checks later on but those are the most important checks at the beginning when the data source window is being initialized. I hope that helps. Thanks! Mike Wong Microsoft Developer Support Hi Mike, Thanks for the explanation. My first question was whether the data source window would work with a 'miscellaneous' project system. I tried the little macro you suggested with the miscellaneous project system and the CodeModel is indeed not defined, so I guess going this route will not work for me. I appreciate the further comments on what the data source tool window looks for, as this may prove to be useful for me in the future, when I implement a custom project system. Thanks, Notre Hi Notre, I don't see anything obvious in addition to the earlier post but there is one area that might hinder some functionality. On right click on a column node in the data sources window, Select Edit dataset with designer. In the xsd designer, if we right click and select the context menu option "view code". I noticed the internal code tries to obtain the codedomprovider from the service provider, a projectitem, or via project language (compares the guid returned from codemodel.language with VB, CSharp, JSharp). If it fails, then possibly the view code command will fail. I think one of the larger issues in the extensibility realm is how you can test and truly integrate your packages into existing features of Visual Studio. It is sort of a two part question - how do you know if you are providing what one package wants? Will you be able to change it if we hit a roadblock? For example, we can test a certain code path out of using the data sources window with a custom project system but we could hit a roadblock with one conditional in the Microsoft.VsDesigner.dll that say checks on language. I think some source code access would be beneficial but that potentially only addresses part of the question. Hmmmmm.... thanks! mike Hi Notre, Would you mind letting me know the result of the suggestions? If you need further assistance, feel free to let me know. I will be more than happy to be of assistance. Have a nice day!
