mobile 显示今日界面时 调出输入法面板 无法使用 拼音输入法中的 拼音功能
也就是没法输入中文,请教各位达人如何解决

输入法面板中左下角的“拼”“英”“符”三个按钮中的“拼”按钮点击无效,其它两个可以正常使用

------解决方案--------------------
这两个事件处理了没?
case WM_ACTIVATE:
// Calling this function when we get WM_ACTIVATE ensures that our
// application will handle the SIP properly. This function does
// nothing when we 're running on Smartphone.
SHHandleWMActivate(hwnd, wp, lp, &sai, 0);
break;

case WM_SETTINGCHANGE:
// This helper function will resize our main application window when the SIP
// goes up and down. Try commenting out this function and see how it affects
// our drawing code. This function is optional, so choose whichever behavior
// you prefer. Again, this function does nothing on Smartphone.
SHHandleWMSettingChange(hwnd, wp, lp, &sai);
break;
