关于在Windows Mobile下今日插件使用WTL的问题

简介

本文讲述在今日插件开发中整合WTL遇到的问题,问题已经解决,看解决部分。

 

问题

最近一段时间都在开发今日插件(Today Plug-in)。开始把代码都写的差不多了,整合了Sqlite和WTL,关于Sqlite和WTL也可以参考之前写的文章。

Windows Mobile下访问Sqlite的Native C++封装

 

Windows Mobile和Wince下的WTL(Windows Template Library)开发

Windows Mobile 和 Wince 下的 WTL(Windows Template Library) 界面开发  

 

最后测试的时候发现今日插件没有正确显示出来。

一般来说一个部署成功的今日插件可以在配置里面显示。如下图:

Start->Settings->Today->Items

today1

我的插件名字叫做Jake’s Today。

 

但是一旦我整合了WTL,插件就不能显示到Today Setting里面了。

#include <atlbase.h>

#if _ATL_VER == 0x900
#define _SECURE_ATL 1
#endif
#include <atlstr.h>

#define _WTL_NO_CSTRING

#include <atlapp.h>

在StdAfx.h加入WTL的头文件,如果仅仅加入ATL支持,是没有问题的,但是一旦加入#include <atlapp.h> 后今日插件就不能显示到Today Setting里面了。如下图:

today2

今日插件Jake’s Today消失了。

我使用Dumpbin查看接口,发现接口与是否整合WTL无关。

同样我把WTL整合的代码去掉,只是加上Sqlite的整合后,也出现同样的问题。目前为止,我没有整合到任何第三方到今日插件中。Windows Mobile下访问Sqlite的Native C++封装

 

这个问题我查找了MSDN没有找到答案,发贴提问了也没有人回答。

How to use WTL in today plug-in DLL

 

由于工期原因,我决定放弃原先的方案,直接使用Win32来完成这个今日插件。如果那位碰到并解决这个问题,请告知,在此先谢了。

 

PS:可能有曲线救国的方法,使用一个today host来调用DLL,因为这个host可以调用C#的DLL的,参考下面的链接。

Creating Managed Today Screen Items

 

解决

 经过Ray和UMU的帮助,找到了解决方法。问题是如果编译出来的DLL依赖于msvcr90d.dll的话,加载就失败了,我想可能是shell32不能成功加载msvcr90d.dll导致的。

下面使用 Dumpbin /imports win32.dll 查看没有使用WTL的版本的DLL。

发现WTL版本比Win32版本增加了对msvcr90d.dll和ole32.dll的依赖。
如果要去掉这些依赖可以通过编译Release版本来解决。
