I am trying to create an VS add in for my reporting engine. I need to be able to loop through each project and then loop through the project and find reports by type. (Like you do with the Bo Mapper) .. i am trying something like below just cannot figure out how to load or just get at the assembly. thanks for  any help

Dim LoProject As Project

Dim loAssembly As Reflection.Assembly

Try

'Check to see if Solution is open, I forget everytime debugging this

If Not _appobject.Solution.IsOpen Then

MessageBox.Show("Please load solution")

Else

For Each LoProject In _appobject.Solution.Projects

'show what projects we have

MessageBox.Show("Project Name: " & LoProject.FullName)

'-- Here i need to be able to load the assembly and then do through the types

' loAssembly = Reflection.Assembly.Load

For Each loType As Type In loAssembly.GetTypes()

If loType.IsSubclassOf(GetType(DevExpress.XtraReports.UI.XtraReport)) Then

Me.ListView1.Items.Add(loType.FullName)

End If

Next

Next

End If

Catch objException As System.Exception

MessageBox.Show(objException.ToString)

End Try

 

You are going to have to use the EnvDTE name space, you will then wan to get a DTE object and once you have that, you will be able to get the ActiveSolution, and enumerate the Projects with the solution:

You will want to create a class and implement the IDTExtensibility2 implemention on your class.  This will require that a method called OnConnection be created.  This method has a parameter called Application which can be typed as a DTE or DTE2 object, and this will be your entry point:

You can also create a wizard class that implements the IWizard interface which will give you a similar starting point and you can tie into template that shows up under (New Item).  This will allow you to provide additional functionality when creating a new item.  This class has a RunStarted method on that implemention and the automationObject is the DTE object in this case.

Once you have the DTE object, you can then get the active solution and project items:

Hi Trent I got the reference but am still having trouble trying to find objects of a certain type. hopefully the code below makes sense. For whatever reason I am missing something and it is driving me nuts Thanks for your help

This code would work normally but as an add in I guess the solution is in a seperate app domain.

That won't work in most cases.  You will have to use the ITypeDiscoveryService to search for the object types.  Using the IsSubClassOf will work under cetain conditions, but you will miss a lot of classes or types.  You can get the ITypeDiscoveryService reference through the GetService method on a provider (IServiceProvider):

Thanks alot Trent I'll try that,  so much for "It will probably be faster to make a small add in to generate report metadata"   Aw well nothing is ever easy is it?

Thanks again for the help

No...add-ins are a MAJOR commitment.  Once you get one going, and have an understanding of the DTE it gets better, but it is a very deep, complex, and painful environment to develop for.  But once you get it integrated and helping you out, then it becomes worth the pain
