1.获取输入法列表
//保存输入法信息的结构
struct _tagInputMethod
{
char szLanguageId[30];
char szLanguageName[100];
char szLanguageImeFileName[100];
HICON hIcon;
};
_tagInputMethod m_InputMethodList[30];
int m_InputMethodCount;
//获取输入法列表
HKEY hKey,hKey1;
DWORD cp=16;
char LanguageId[15];
CString szID;
CString szKeyName,szKeyName1;
szKeyName = "Keyboard Layout\\Preload";
szKeyName1 = "System\\CurrentControlSet\\Control\\Keyboard Layouts\\";
int i=0;
szID.Format("%d",i+1);
DWORD lpT=REG_SZ;
if(::RegOpenKey(HKEY_CURRENT_USER,szKeyName,&hKey)==ERROR_SUCCESS )
{
while(::RegQueryValueEx(hKey,szID,NULL,&lpT,(LPBYTE)LanguageId,&cp) == ERROR_SUCCESS )
{
CString szTempName;
szTempName = szKeyName1 + (LPCTSTR)(LPTSTR)LanguageId;
if(RegOpenKey(HKEY_LOCAL_MACHINE,szTempName,&hKey1)==ERROR_SUCCESS )
{
char szLanguageName[100];
memset(szLanguageName,0,100);
char szImeFileName[100];
memset(szImeFileName,0,100);
char szImeFileName_Layout[100];
memset(szImeFileName_Layout,0,100);
char Temp[100];
memset(Temp,0,100);
DWORD lpSLen=100;
if(RegQueryValueEx(hKey1,"Layout text",NULL,&lpT,(LPBYTE)szLanguageName,&lpSLen)==ERROR_SUCCESS)
{
strcpy(m_InputMethodList[i].szLanguageId,LanguageId);
strcpy(m_InputMethodList[i].szLanguageName,szLanguageName);
}
//ImeFileName
lpSLen=100;
RegQueryValueEx(hKey1,"IME file",NULL,&lpT,(LPBYTE)szImeFileName,&lpSLen);
if (strlen(szImeFileName)>0)
{
strcpy(Temp,szImeFileName);
}
else
{
lpSLen=100;
RegQueryValueEx(hKey1,"Layout File",NULL,&lpT,(LPBYTE)szImeFileName_Layout,&lpSLen);
if (strlen(szImeFileName_Layout)>0)
{
strcpy(Temp,szImeFileName_Layout);
}
}
strcpy(m_InputMethodList[i].szLanguageImeFileName,Temp);
//从IME的文件里取出16*16图标
HICON hSmallImeIcon[1];
int _ImeIconCount=ExtractIconEx(Temp,0,NULL,hSmallImeIcon,1);
if (_ImeIconCount==0)
{
hSmallImeIcon[0]=LoadIcon(AfxGetApp()->m_hInstance,(LPCTSTR)IDI_UnKnowInputMethodIcon);
}
m_InputMethodList[i].hIcon=hSmallImeIcon[0];
}
::RegCloseKey(hKey1);
i++;
szID.Format("%d",i+1);
m_InputMethodCount=i;
}
}
::RegCloseKey(hKey);
2.通过编程方式切换输入法
HKL hkl=LoadKeyboardLayout(szLanguageId,KLF_ACTIVATE);
::PostMessage(::GetForegroundWindow(),WM_INPUTLANGCHANGEREQUEST,TRUE,(LPARAM)hkl);
获取系统当前的输入法列表并通过编程方式切换输入法
