ZoomIn插件制作（VS2010 arcObject10.2 ）全网应该是唯一的

这个过程就是制作ArcMap插件的过程，说实话挺恶心的，为什么不用VS2013呢？主要是环境有问题。

Go! Let‘s do it！

一、新建ATL项目（项目命名Demo即可）

第二步直接点完成、无需修改当中项：

第三步右键当前项目Demo 添加类

选择“ATL简单对象”

点击添加而后命名ZoomIn 简洁明白大方：

然后在接口处选择“自定义” 主要是为了后面实现ICommand接口

完成即可；

而后对Demo.idl 部分修改：

接下来是引入esri对象库文件（在stdafx.h当中引入）：


#pragma warning(push)
#pragma warning(disable : 4192)
  //disables warning: automatically excluding 'name' while importing type library 'library'
//import esriSystem.olb
#import 'C:\Program Files (x86)\ArcGIS\Desktop10.2\com\esriSystem.olb' raw_interfaces_only raw_native_types no_namespace named_guids exclude('OLE_COLOR', 'OLE_HANDLE', 'VARTYPE', 'XMLSerializer') rename('min','esrimin') rename('max','esrimax') rename('GetObject','esriGetObject') rename('GetJob','esriGetJob')
//import esriSystemUI.olb

//import esriGeoDatabase.olb
#import 'C:\Program Files (x86)\ArcGIS\Desktop10.2\com\esriGeoDatabase.olb' raw_interfaces_only raw_native_types no_namespace named_guids rename('GetMessage','esriGetMessage')

#import 'C:\Program Files (x86)\ArcGIS\Desktop10.2\com\esriCarto.olb' raw_interfaces_only raw_native_types no_namespace named_guids exclude('UINT_PTR') rename('PostMessage','esriPostMessage')
//import esriControls.olb
#import 'C:\Program Files (x86)\ArcGIS\Desktop10.2\com\esriControls.olb' raw_interfaces_only raw_native_types no_namespace named_guids rename('DrawText','esriDrawText')
#import 'C:\Program Files (x86)\ArcGIS\Desktop10.2\com\esriSystemUI.olb' raw_interfaces_only, raw_native_types, no_namespace, named_guids, auto_search
#import 'C:\Program Files (x86)\ArcGIS\Engine10.2\com\esriSystemUI.olb' raw_interfaces_only, raw_native_types, no_namespace, named_guids, auto_search
#pragma warning(pop)

然后转到类视图右键CZoomIn ------> 添加 -----> 实现接口（ICommand接口）

完成即可；

接下来就是对这些方法进行实现

转到ZoomIn.h 删除原因的方法块：

转到ZoomIn.cpp去实现这些方法


// ZoomIn.cpp : CZoomIn 的实现
#include 'stdafx.h'
#include 'ZoomIn.h'
// CZoomIn
IHookHelperPtr m_ipHookHelper;
STDMETHODIMP CZoomIn::get_Enabled(VARIANT_BOOL *Enabled)
{
  if (Enabled == NULL)
    return E_POINTER;
  *Enabled = VARIANT_TRUE; // Enable the tool always
  return S_OK;
}
CZoomIn::CZoomIn()
{
  m_hBitmap = ::LoadBitmap(_AtlBaseModule.GetResourceInstance(), MAKEINTRESOURCE(IDB_BITMAP1));
}
STDMETHODIMP CZoomIn::get_Name(BSTR *Name)
{
  if (Name == NULL)
    return E_POINTER;
  *Name = ::SysAllocString(L'ZoomInDu');
  return S_OK;
}
STDMETHODIMP CZoomIn::get_Caption(BSTR *Caption)
{
  if (Caption == NULL)
    return E_POINTER;
  *Caption = ::SysAllocString(L'ZoomIn*Du');
  return S_OK;
}
STDMETHODIMP CZoomIn::get_Category(BSTR *Category)
{
  if (Category == NULL)
    return E_POINTER;
  *Category = ::SysAllocString(L'GisTools');
  return S_OK;
}
STDMETHODIMP CZoomIn::get_Bitmap(OLE_HANDLE *Bitmap)
{
  if (Bitmap == NULL)
    return E_POINTER;
  *Bitmap = (OLE_HANDLE)m_hBitmap;
  return S_OK;
}
STDMETHODIMP CZoomIn::OnCreate(IDispatch *hook)
{
  m_ipHookHelper.CreateInstance(CLSID_HookHelper);
  HRESULT hr = m_ipHookHelper->putref_Hook(hook);
  return hr;
}
STDMETHODIMP CZoomIn::OnClick()
{
  // HRESULT checking omitted for clarity
  IActiveViewPtr ipActiveView;
  m_ipHookHelper->get_ActiveView(&ipActiveView);
  IEnvelopePtr ipEnv;
  ipActiveView->get_Extent(&ipEnv);
  ipEnv->Expand(0.5, 0.5, VARIANT_TRUE);
  ipActiveView->put_Extent(ipEnv);
  ipActiveView->Refresh();
  return S_OK;
}
