This message is sent to an application when a window of the application is activated.
At a Glance
| Header file: | Imm.h |
| Windows CE versions: | 2.10 and later (Japanese version 1.0 and later) |
Syntax
WM_IME_SETCONTEXT fSet = (BOOL) wParam;
iShow = (DWORD) lParam;
Parameters
fSet
Boolean that is set to TRUE if the input context is active, or to a FALSE, the context is inactive.
iShow
Show flags. It can be a combination of the following values:
| Value | Description |
| ISC_SHOWUICOMPOSITIONWINDOW | Shows the composition window by UI window. |
| ISC_SHOWUIGUIDWINDOW | Shows the guide window by UI window |
| ISC_SHOWUISOFTKBD | Shows the soft keyboard by UI window |
| ISC_SHOWUICANDIDATEWINDOW | Shows the candidate window of Index 0 by UI window. |
| ISC_SHOWUICANDIDATEWINDOW << 1 | Shows the candidate window of Index 1 by UI window. |
| ISC_SHOWUICANDIDATEWINDOW << 2 | Shows the candidate window of Index 2 by UI window. |
| ISC_SHOWUICANDIDATEWINDOW << 3 | Shows the candidate window of Index 3 by UI window. |
If the application draws the composition window, the default IME window does not need to show its composition window. In this case, the application must clear the ISC_SHOWUICOMPOSITIONWINDOW value from the lParam parameter before passing the message to the DefWindowProc or ImmIsUIMessage functions.
Return Values
Returns the value returned by DefWindowProc or ImmIsUIMessage.
Remarks
Windows CE applications should pass this message to the DefWindowProc function.
