获取输入法列表

现在好多在CE下做开发的都不使用CE的界面，所以也无法使用系统提供的输入法切换的功能。

 

如何自己枚举输入法，显示在自己应用的界面中，供用户选择呢？

 

以前在CE5下研究过一段时间相关的东东，分享出来大家一起学习。以求有抛砖引玉的作用，小心哦，不要被砖拍到，嘿嘿...

 

主要是下面这个类，一个.h文件：

调用示例：

// TestIM.cpp : Defines the entry point for the application. // #include "stdafx.h" #include "InputOper.h" int WINAPI WinMain( HINSTANCE hInstance, HINSTANCE hPrevInstance, LPTSTR lpCmdLine, int nCmdShow) { CInputLanguage *InputTest; InputLink *pLPList = NULL; InputLink *pTmpLPList = NULL; // TODO: Place code here. InputTest = new CInputLanguage(); pLPList = InputTest->GetInputIMList(); pTmpLPList = pLPList; while(NULL != pTmpLPList) { //DrawText(hdc, pTmpLPList->tcName, NameBufSize, &rt, // DT_SINGLELINE | DT_VCENTER | DT_CENTER); pTmpLPList = pTmpLPList->pNext; RETAILMSG(1,(L"SIP name of No.%d is %s/r/n",pTmpLPList->tcName)); } InputTest->SelectInputIM(pTmpLPList); return 0; }
