急啊，公司季度考试，桌面右键菜单实现，点击就是不动作，怎么办！

[大鸭子男孩]

实在不会，这能现学，比着别人的修改的，原文：http://www.cppblog.com/shly/archive/2013/10/07/157894.html
到底哪里出错了，在桌面右键后，然后点击添加的“我是显卡选项” 就是没反应啊！
现在：

#include "CtxMenuExt.h"
#include "shlobj.h"

单步跟踪看看！确定你点击“我是显卡选项”的时候，是否得到相关协议的第一步相应！ 并通过此协议是否成功调用相关接口函数！

lz遇到的这个问题我前几个月也见过,但是最后通过多方面的尝试,发现是32位和64位系统的问题,如果你的电脑是64位系统请尝试编译64位dll来注册,希望能帮到你.

你们公司是学校么？还季度考试？？

[大鸭子男孩]

谢谢你们 ，最后还是找不到哪里错了，个人猜测是InsertMenuItem之后 return MAKE_HRESULT的值有问题，改用InsertMenu了

加了点注释,代码扣给你研究下

HRESULT CUploadMenuExt::QueryContextMenu (HMENU hmenu, 
                                      UINT uMenuIndex, 
                                      UINT uidFirstCmd,
                                      UINT uidLastCmd, 
                                      UINT uFlags )
{

	if (uFlags & CMF_DEFAULTONLY)
	{
		return MAKE_HRESULT(SEVERITY_SUCCESS, FACILITY_NULL, 0);
	}
	
	UINT uCmdID = uidFirstCmd;
	//添加横线
	InsertMenu (hmenu, uMenuIndex, MF_SEPARATOR | MF_BYPOSITION, 0, NULL);
	uMenuIndex++;

	HMENU hSubMenu = CreateMenu();
	//添加子菜单
	if(hSubMenu)
	{	
		InsertMenu (hSubMenu, 0, MF_BYPOSITION, uCmdID++, _T("上传至个人目录"));
		SetMenuItemBitmaps(hSubMenu, 0, MF_BYPOSITION, m_hBitmapUpLoad, m_hBitmapUpLoad);
	}
	//添加菜单项
	InsertMenu (hmenu, uMenuIndex, MF_STRING | MF_POPUP | MF_BYPOSITION,
		(UINT_PTR)hSubMenu, _T("安全小助手"));
	SetMenuItemBitmaps(hmenu, uMenuIndex, MF_BYPOSITION, m_hBitmapMenu, m_hBitmapMenu);
	uMenuIndex++;
	
	//添加横线
	InsertMenu(hmenu, uMenuIndex, MF_SEPARATOR | MF_BYPOSITION, 0, NULL);
	 uMenuIndex++;

	return MAKE_HRESULT ( SEVERITY_SUCCESS, FACILITY_NULL, 1  );

}


//处理菜单响应
HRESULT CUploadMenuExt::InvokeCommand (LPCMINVOKECOMMANDINFO pCmdInfo )
{	
	if (0!=HIWORD(pCmdInfo->lpVerb))
