Question

Newbie Visual Studio扩展问题：我想创建一个扩展来监视击键并将统计信息报告给可停靠窗口（“可停靠”，如解决方案资源管理器或属性窗口）。我在查找编辑器中提供的不仅仅是语法高亮的好教程时遇到了麻烦。

这是否可以作为扩展？或者我是否需要创建加载项？我最感兴趣的课程是完成这些高级任务？

Answer 1

您将能够通过Visual Studio加载项轻松实现您的想法。如果要创建VS样式ToolWindow，请按照下面的步骤操作。在示例中，VS ToolWindow承载TreeView，但您可以使用您选择的控件。我更喜欢C ++ CLI，但通常下面的步骤对C＃或VB.Net也应该有效。

通过 File-＆gt; New-＆gt; Project-＆gt; OtherProjectTypes-＆gt; Extensibility-＆gt; VS Add-In

将以下内容实施到加载项类

中

public ref class Connect : public IDTExtensibility2, public IDTCommandTarget
{
public:
...
private:
   literal String^ VSToolWinGuid = "{6CCD0EE9-20DB-4636-9149-665A958D8A9A}";

   DTE2^ appObject;    // object which lets us access the IDE
   AddIn^ addInInstance;   // the AddIn object itself
   Window^ MainWindow;     // VS style tool Window
   TreeView^ FormTreeView; 

   // Instance of the Add-In button located in the VS IDE Toolbar
   CommandBarButton^ StdCommandBarButton;  

   void InitializeToolBarButton(); // Creates a button on the Standard Toolbar
   void ShowAddInWindow();     // Creates and displays the Tool Window
...
};



void Connect::OnConnection(...)
{
   appObject = dynamic_cast<DTE2^>(Application);
   addInInstance = dynamic_cast<AddIn^>(AddInInst);

   // Initialize the add-in when VS is setting up it's user interface
   if (ext_ConnectMode::ext_cm_UISetup==ConnectMode)
      InitializeToolBarButton();
}


void Connect::Exec(...)
{
   handled = false;
   if (vsCommandExecOption::vsCommandExecOptionDoDefault == ExecuteOption)
   {
      // when the ToolBar Button is clicked through the UI
      if (!CmdName->CompareTo("FormBrowserAddIn.Connect.FormBrowser"))
      {             
         ShowAddInWindow();
         handled = true;
         return;
      }
   }
}


void Connect::InitializeToolBarButton()
{
   try
   {    
      Command^ command = nullptr;           
      try
      {  // obtain the command if it is already created         
         command = appObject->Commands->Item(addInInstance->ProgID + "." + AddInName, -1);
      }
      catch(Exception^){}

      // create the command if does not exists
      if (nullptr == command)
      {
         // it is better to use the newest Commands2, because it allows to create
         // the ToolBar button with the style definition at once
         EnvDTE80::Commands2^ commands2 = safe_cast<EnvDTE80::Commands2^>(appObject->Commands);

         // optional, determines which environment contexts (debug mode, design mode, ...) show the command
         Array^ contextGUIDs = Array::CreateInstance(Object::typeid, 0);                

         // create the ToolBar button for our Add-In
         command = commands2->AddNamedCommand2(addInInstance, 
              AddInName, AddInCaption, AddInToolTip, true, 59, contextGUIDs,
             (int)(vsCommandStatus::vsCommandStatusSupported | vsCommandStatus::vsCommandStatusEnabled),
             (int)vsCommandStyle::vsCommandStylePict, vsCommandControlType::vsCommandControlTypeButton);
       }

       // Obtain the Standard command bar and insert our ToolBar button there
       VisualStudio::CommandBars::CommandBars^ commandBars;
       commandBars = (VisualStudio::CommandBars::CommandBars^)appObject->CommandBars;
       CommandBar^ stdCommandBar = commandBars["Standard"];
       StdCommandBarButton = (CommandBarButton^)command->AddControl(stdCommandBar, stdCommandBar->Controls->Count+1);
    }
    catch(Exception^ e)
    {
        MessageBox::Show(e->ToString());
    }
}


void Connect::ShowAddInWindow()
{
   try
   {
      if (nullptr == MainWindow)
      {
         // obtain the assembly of the TreeView
         String^ TreeViewFullName = "System.Windows.Forms.TreeView";
         String^ assembly = Reflection::Assembly::GetAssembly(System::Windows::Forms::TreeView::typeid)->Location;

         // create the VS style Tool Window
         Object^ UserCtrlObject = nullptr;
         EnvDTE80::Windows2^ win = (EnvDTE80::Windows2^)appObject->Windows;
         MainWindow = win->CreateToolWindow2(addInInstance, assembly, TreeViewFullName, AddInCaption, VSToolWindowGuid, UserCtrlObject);

         // set-up the tree view
         FormTreeView = (TreeView^)UserCtrlObject;      
      }

      // refresh the content and make the add-in visible
      RefreshTreeView();
      MainWindow->Visible = true;
   }
   catch (Exception^ e)
   {
      MessageBox::Show(e->ToString());
   }
}

我从未尝试过处理加载项中的关键事件，但我希望您能找到答案here。

无论如何，你可以找到很多好的教程here或者搜索MZTools。
