For Windows Mobile devices, the SHSetInputContext function changes the state of a context feature of an input window. This function allows run-time modification of the contextual properties of an input window.

Syntax

HRESULT SHSetInputContext (
  HWND hwnd,
  DWORD dwFeature,
  const LPVOID lpValue
);

Parameters

• hwnd
  [in] Handle to the window whose context feature is being set.

• dwFeature
  [in] The context feature to change, specified by a value from the SHIC_FEATURE enumeration. For more information, see Remarks.

• lpValue
  [in] The new value assigned to feature. For more information, see Remarks.

Return Value

• S_OK
  The function completed successfully.

• ERROR_INVALID_PARAMETER
  The hwnd parameter was NULL, or the lpValue parameter was NULL when that was not a valid option for the specified dwFeature.

• ERROR_NOT_SUPPORTED
  The feature specified by the dwFeature parameter was invalid.

• ERROR_INVALID_DATA
  The value specified by lpValue is not a valid option for the specified dwFeature.

Remarks

The features that can be changed are determined by the SHIC_FEATURE enumeration. One of the enumerators of SHIC_FEATURE must be passed as the dwFeature parameter of this function. Each enumerator has corresponding valid values that can be passed in the lpValue parameter.

For any context feature that is not explicitly defined through this function, the value of that feature is taken from the window's parent window.

Applications that use SHSetInputContext with the SHIC_FEATURE enumeration values SHIC_FEATURE_CLASS or SHIC_CLASS_* must initialize the COM library (using CoInitializeEx) before creating the edit control.
