Debug custom dll that is being referenced in visual studio macro

Question

I previously asked: Add dll reference to visual studio macros

the idea of creating the macros in my language (C#) makes it easier to create the macros. The prob

Answer 1

I have yet another answer which is even better!

The only reason why I created the addin is because I needed a reference of the DTE. Why not reference the dte that I need.

The the algorithm is as follow:

1. Use class Ide to get the DTE of whatever instance of visual studio.

2. Once you have that dte create the macro.

Here is the Ide class:

public class Ide
{        
    [DllImport("ole32.dll")]
    private static extern void CreateBindCtx(int reserved, out IBindCtx ppbc);

    [DllImport("ole32.dll")]
    private static extern void GetRunningObjectTable(int reserved, out IRunningObjectTable prot);

    public static DTE2 GetDte(string solutionName)
    {
        DTE2 dte = null;

        GetDte((displayName, x) =>
        {
            if (System.IO.Path.GetFileName(x.Solution.FullName).Contains(solutionName))
            {
                dte = x;
                return false; // we found it stop seraching
            }
            else
            {
                return true; // continue searching
            }

        });

        return dte;
    }

    public static DTE2 GetDte(int processId)
    {
        DTE2 dte = null;

        GetDte((displayName, x) =>
        {
            if (displayName.Contains(processId.ToString()))
            {
                dte = x;
                return false; // stop searching we found matching dte
            }
            else
            {
                return true; // continue searching
            }
        });

        return dte;
    }

    public static List GetAllDte()
    {
        List list = new List();
        GetDte((displayName, x) =>
        {
            list.Add(x);
            return true; // continue serching we want all dte's
        });
        return list;
    }

    private static void GetDte(Func foo)
    {
        Dictionary dtesProcessIds = new Dictionary();

        //rot entry for visual studio running under current process.            
        IRunningObjectTable rot;
        GetRunningObjectTable(0, out rot);
        IEnumMoniker enumMoniker;
        rot.EnumRunning(out enumMoniker);
        enumMoniker.Reset();
        IntPtr fetched = IntPtr.Zero;
        IMoniker[] moniker = new IMoniker[1];
        while (enumMoniker.Next(1, moniker, fetched) == 0)
        {
            IBindCtx bindCtx;
            CreateBindCtx(0, out bindCtx);
            string displayName;
            moniker[0].GetDisplayName(bindCtx, null, out displayName);
            object comObject;
            rot.GetObject(moniker[0], out comObject);

            if (comObject != null)
            {
                DTE2 dteCurrent = null;
                try
                {
                    dteCurrent = (EnvDTE80.DTE2)comObject;

                    // if solution is not open continue
                    // this will cause an exception if it is not open
                    var temp = dteCurrent.Solution.IsOpen;

                    string solName = dteCurrent.Solution.FullName;

                    // if there is an instance of visual studio with no solution open continue                        
                    if (string.IsNullOrEmpty(solName))
                    {
                        continue;
                    }

                    // avoid adding duplicate ide's
                    if (dtesProcessIds.ContainsKey(displayName) == false)
                    {
                        dtesProcessIds.Add(displayName, displayName);
                    }
                    else
                    {
                        continue;
                    }

                }
                catch (System.Runtime.InteropServices.COMException e)
                {
                    continue;
                }
                catch (Exception e)
                {
                    continue;
                }
                if (dteCurrent != null)
                {
                    var cont = foo(displayName, dteCurrent);

                    if (cont == false)
                        return;
                }
            }

        }
    }
}

then if I have an instance of visual studio runing that contains a solution with the name ConsoleApp1 then I will be able to do:

 var dte = Ide.GetDte("ConsoleApp1");
 dte.ActiveDocument.Selection.Insert("My macro is working!");

and the text My macro is working! will be inserted in the active document. make sure there is an active document though
