Windows 7 - to change the focus window input method,

1. GetForegroundWindow return window handle to 0, and cannot obtain,

Exactly how to get focus window,

 

DWORD dwThread=GetWindowThreadProcessId (GetForegroundWindow (), NULL); 
AttachThreadInput (dwThread, GetCurrentThreadId (), TRUE); 
HWND hFocus=GetFocus (); 
STD: : cout & lt; AttachThreadInput (dwThread, GetCurrentThreadId (), FALSE); 



- to change the focus window input method, 

Void SetImeConversionStatus (HWND& HWND, _IME_Mode mode) 
{
HIMC HIMC=ImmGetContext (HWND); 

If (mode==_IME_Off) 
{
//the IME オ フ 
ImmSetOpenStatus (hImc, FALSE); 
} 
The else 
{
ImmSetOpenStatus (hImc, TRUE); 
DWORD dwConversion=0; 
DWORD dwSentence=0; 
ImmGetConversionStatus (hImc, & amp; DwConversion, & amp; DwSentence); 
STD: : cout & lt; The switch (mode) 
{
Case _IME_Hiragana://ひ ら が な 
DwConversion |=IME_CMODE_NATIVE | IME_CMODE_FULLSHAPE; 
DwConversion & amp;=~ IME_CMODE_KATAKANA; 
break; 
Case _IME_Katakana://Angle カ タ カ ナ 
DwConversion |=
IME_CMODE_NATIVE | IME_CMODE_FULLSHAPE | IME_CMODE_KATAKANA; 
break; 
Case _IME_Alpha://the Angle of the number of 
DwConversion |=IME_CMODE_FULLSHAPE; 
DwConversion & amp;=~ (IME_CMODE_NATIVE | IME_CMODE_KATAKANA); 
break; 
Case _IME_KatakanaHalf://half Angle カ タ カ ナ 
DwConversion |=IME_CMODE_NATIVE | IME_CMODE_KATAKANA; 
DwConversion & amp;=~ IME_CMODE_FULLSHAPE; 
break; 
Case _IME_AlphaHalf://half Angle the number 
DwConversion & amp;=
~ (IME_CMODE_NATIVE | IME_CMODE_FULLSHAPE | IME_CMODE_KATAKANA); 
break; 
Default: 
break; 
} 
ImmSetConversionStatus (hImc dwConversion, dwSentence); 
} 
ImmReleaseContext (HWND, hImc); 
} 

CodePudding user response:

Takes time, Sleep (1000), and have found the reason,

But I don't know why HIMC HIMC=ImmGetContext (HWND);

HImc always returns NULL, other processes cannot be obtained through ImmGetContext other window hImc
