Return value

Remarks
The EM_GETLINECOUNT message retrieves the total number of text lines, not just the number of lines that are currently visible.
If the Wordwrap feature is enabled, the number of lines can change when the dimensions of the editing window change.
Rich Edit: Supported in Microsoft Rich Edit 1.0 and later. For information about the compatibility of rich edit versions with the various system versions, see About Rich Edit Controls.
