Parameters

wParam
Specifies one of the following values.
SES_EMULATESYSEDIT
When this bit is on, rich edit attempts to emulate the system edit control.
SES_BEEPONMAXTEXT
Rich Edit will call the system beeper if the user attempts to enter more than the maximum characters.
SES_EXTENDBACKCOLOR
Extends the background color all the way to the edges of the client rectangle.
SES_USEAIMM
Uses the AIMM input method component that ships with Microsoft® Internet Explorer 4.0 or later.
SES_UPPERCASE
Converts all input characters to uppercase.
SES_LOWERCASE
Converts all input characters to lowercase.
SES_NOINPUTSEQUENCECHK
When this bit is on, rich edit does not verify the sequence of typed text. Some languages (such as Thai and Vietnamese) require verifying the input sequence order before submitting it to the backing store.
SES_XLTCRCRLFTOCR
Turns on translation of CRCRLFs to CRs. When this bit is on and a file is read in, all instances of CRCRLF will be converted to hard CRs internally. This will affect the text wrapping. Note that if such a file is saved as plain text, the CRs will be replaced by CRLFs. This is the .txt standard for plain text.
lParam
A mask consisting of one or more of the wParam values. Only the values specified in this mask will be set or cleared. This allows a single flag to be set or cleared without reading the current flag states.

Return Value

The return value is the state of the edit style flags after rich edit has attempted to implement your edit style changes. The edit style flags are a set of flags that indicate the current edit style, made up of the values in the preceding table .
