Hello all,
I am looking for some samples on using the IDE Extensibility's CodeElements.
I am building some add-ins and I have a couple of problems:
1 - Adding a constructor to a class using:
EnvDTE.CodeFunction cF =
codeClss.AddFunction("Account",EnvDTE.vsCMFunction.vsCMFunctionConstructor,0
,-1,EnvDTE.vsCMAccess.vsCMAccessPublic,"");
This gives me the error: Invalid parameter! But it does not say which one:)
2 - Also I am able to create properties using:
EnvDTE.CodeProperty codeProp =
codeClss.AddProperty("Name","Name","string",-1,EnvDTE.vsCMAccess.vsCMAccessP
ublic, "");
but I can not modify the getter or the setter after that.
I will appreciate any help in getting some sample code on manipulating these
CodeElements.
Regards,
Santos

Santos-
Ok, so you had two issues:
-an invalid parameter for the constructor you were adding
and
- modifying the getter and setter for the property you created.
For the constructor issue:
Currently, there is an issue in extensibility with creating constructors in
C#; we are addressing it now...
In the meantime, there are two approaches to creating a constructor:
Solution 1
The first solution is to insert a string literal into the class, using the
EditPoint object. Here's a bit of macro code that creates a class in the
code file "newfile.cs" and adds a constructor. You may notice that this is
VB code - the other solution we provided is in C#, but takes a different
approach from the design you were using.
Public Sub AddAConstructor()
Dim proj As Project
proj = DTE.Solution.Projects.Item(1)
Dim pi As ProjectItem
pi = proj.ProjectItems.Item("newfile.cs")
Dim games As CodeNamespace
Dim name As String = InputBox("namespace")
games = pi.FileCodeModel.AddNamespace(name)
' Add a class to the namespace.
Dim chess As CodeClass
chess = games.AddClass("Chess")
Dim ep As EditPoint = _
chess.GetEndPoint( _
EnvDTE.vsCMPart.vsCMPartBody).CreateEditPoint()
ep.LineUp(1)
Dim indent As String = ControlChars.CrLf & ControlChars.Tab & _
ControlChars.Tab
Dim constructor As String = _
indent & "Chess()" & _
indent & "{" & _
indent & ControlChars.Tab & "int i = 10;" & _
indent & ControlChars.Tab & _
"MessageBox.Show(i.ToString());" & _
indent & "}" & ControlChars.CrLf
ep.Insert(constructor)
End Sub
Solution 2
The second solution uses the System.CodeDom namespace to generate code. This
bit of C# code creates a class and writes the class to the console.
using System;
using System.IO;
using System.CodeDom;
using System.CodeDom.Compiler;
namespace ConstructorTest1
{
/// <summary>
/// Summary description for Class1.
/// </summary>
class Class1
{
/// <summary>
/// The main entry point for the application.
/// </summary>
[STAThread]
static void Main(string[] args)
{
CodeDomProvider csharpProv;
ICodeGenerator csharpGenerator;
StringWriter s = new StringWriter();
CodeCompileUnit ccUnit = new
CodeCompileUnit();
csharpProv = new
Microsoft.CSharp.CSharpCodeProvider();
csharpGenerator =
csharpProv.CreateGenerator(s);
CodeNamespace codens = new
CodeNamespace();
CodeGeneratorOptions cgOpt = new
CodeGeneratorOptions();
codens.Name = "Games";
ccUnit.Namespaces.Add(codens);
CodeTypeDeclaration class1 = new
CodeTypeDeclaration();
class1.Name = "Chess";
class1.IsClass = true;
codens.Types.Add(class1);
CodeConstructor cctor = new
CodeConstructor();
cctor.Attributes =
MemberAttributes.Public;
cctor.Statements.Add(
new CodeSnippetStatement("for(int i=0; i<3; i++);"));
class1.Members.Add(cctor);
csharpGenerator.GenerateCodeFromCompileUnit(
ccUnit, s, cgOpt);
Console.WriteLine(s);
}
}
}
For the getter and the setter issue, we were unable to figure out exactly
what you were trying to accomplish - what do you want to change about the
getter and setter?
If you need further clarification of the above, or have any other questions,
please holler.
Thanks
