繼續編寫VisualStudio插件。這次我編寫的插件叫DevAssist（意思是開發助手）。在看了前面的文章之後你知道了一個VisualStudio插件一般是由兩個工程組成的：功能dll和資源dll。首先我們先建一個功能dll——DevAssist，具體過程請參考第一篇：自己動手編寫一個VS插件（一）。然後我們再建一個資源dll——DevAssistUI。
編譯一下DevAssistUI工程，結果出錯：
generalerror c1010070: Failed to load and parse the manifest
上網查了下，發現編譯一個空工程會出現這個錯誤，於是把一個位圖資源導入進去再編譯就沒有這個錯誤了。再編譯DevAssistUI工程，還有錯誤：
1>------已啓動生成: 項目: DevAssistUI, 配置: Debug Win32 ------
1>正在鏈接...
1>LINK: error LNK2001: 無法解析的外部符號 __DllMainCRTStartup@12
1>E:\PIE3_src\outdir/Debug/1033\DevAssistUI.dll: fatal error LNK1120: 1 個無法解析的外部命令
1>生成日誌保存在“file://E:\PIE3_src\Intdir\Debug\DevAssistUI\BuildLog.htm”
1>DevAssistUI - 2 個錯誤，0 個警告
========== 生成: 成功 0 個，失敗 1 個，最新 0 個，跳過 0 個 ==========
在工程設置裏把該工程改爲無入口點即可，如下圖： 
現在我們開始實現創建一個工具欄並把它顯示出來。首先需要在AddIn.rgs中指定資源dll，具體是在HKCU段添加SatelliteDllName和SatelliteDllPath兩個變量，具體如下：
HKCU

{

valFriendlyName = s 'DevAssist -開發助手。'
valDescription = s 'DevAssist - 用於輔助開發。'
valAboutBoxDetails = s '有關DevAssist的詳細信息，請參見DevAssist 站點\r\nhttp://blog.csdn.net/clever101\r\n關於客戶支持，請致電: 1-800-xxx-xxxx。\r\n版權所有(C) 2013 DreamStudio Inc.'
valAboutBoxIcon = s '%MODULE%,1'

val SatelliteDllName = s 'DevAssistUI.dll'
valSatelliteDllPath = s '%MODULE_PATH%'
}
}
}
}
}
}
}
然後開始添加創建工具欄的代碼：
// 按鈕信息結構體
struct stCommandInfo
{
LPCTSTR m_name; // 按鈕名字
LPCTSTR m_strTip; // 按鈕提示
BOOL m_hasIcon; // 是否有圖標
UINT m_bitmapID; // 對應的位圖ID
UINT m_cmdID; // 命令ID
};

{
if(pCommandBars == NULL || pOut == NULL)
return E_FAIL;
CComVariant varToolbarName(szToolbarName);
int nToolBars = 0;
HRESULT hr = pCommandBars->get_Count(&nToolBars);
for(int idx = 1; idx <= nToolBars; idx++)
{
CComPtr<CommandBar> pCommandBar;
hr = pCommandBars->get_Item(CComVariant(idx), &pCommandBar);
if(FAILED(hr))
continue;
BSTR bsName = NULL;
if(pCommandBar != NULL)
pCommandBar->get_Name(&bsName);
if(CComVariant(bsName) == varToolbarName)
{
*pOut = pCommandBar;
(*pOut)->AddRef();
break;
}
SysFreeString(bsName);
hr = E_FAIL;
}
return hr;
}
// When run, the Add-in wizard prepared the registry for the Add-in.

wcscpy_s(item, 256, MODULE_NAME);

HRESULT hr = pCommands->Item(CComVariant(item), -1, &pCommand);
if (SUCCEEDED(hr))

}
int curToolbarPosition = 1;

修改後工具欄按鈕都亮了。

原因分析：對於ULONG_PTR類型，VS2008的類型庫和windowsSDK出現重定義。解決辦法是：在導入VS2008的類型庫時重命名ULONG_PTR類型(LONG_PTR也有類似問題)，如下：
#import "libid:80cc9f66-e7d8-4ddd-85b6-d9e6cd0e93e2" version("8.0") lcid("0") raw_interfaces_only named_guids rename("ULONG_PTR","ULONG_PTRDTE") rename("LONG_PTR","LONG_PTRDTE")b. 鏈接器工具錯誤 LINK : fatal error LNK1168: 無法打開..\outdir\Debug\DevAssist.dll 進行寫入。
解決辦法：
在VS裏的外接程序管理器裏把啓動去掉，如下圖：
然後編譯如果還要錯誤就重啓VS，如果還有錯誤就打開任務管理器，殺死所有explorer.exe,然後新建一個explorer進程。
c.修改工具欄按鈕的位圖資源或提示，但是工具欄總是不更新。
在工具欄的自定義對話框中將工具欄刪掉，如下：
然後重啓VS再啓動插件即可看到工具欄的更新狀態。
