お返事ありがとうございます。
以下のようなプログラムで、無事に動作させることができました。
関数の宣言等：
Public Declare Function SendMessage Lib "user32.dll" Alias "SendMessageA" ( _
ByVal hWnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long
Public Type CHARFORMAT2
cbSize As Integer
wPad1 As Integer
dwMask As Long
dwEffects As Long
yHeight As Long
yOffset As Long
crTextColor As Long
bCharSet As Byte
bPitchAndFamily As Byte
szFaceName As String * 32
wPad2 As Integer
wWeight As Integer
sSpacing As Integer
crBackColor As Long
lcid As Long
dwReserved As Long
sStyle As Integer
wKerning As Integer
bUnderlineType As Byte
bAnimation As Byte
bRevAuthor As Byte
bReserved1 As Byte
End Type
Public Const EM_GETCHARFORMAT = &H43A
Public Const EM_SETCHARFORMAT = &H444
Public Const SCF_SELECTION = &H1
Public Const CFM_BACKCOLOR = &H4000000
マウスでテキストを選択した時、選択範囲のテキストの背景色を赤色にするプログラム：
Private Sub RichTextBox1_MouseUp(Button As Integer, Shift As Integer, x As Single, y As Single)
Dim cf2 As CHARFORMAT2
cf2.cbSize = Len(cf2)
SendMessage RichTextBox1.hWnd, EM_GETCHARFORMAT, SCF_SELECTION, cf2
cf2.dwMask = CFM_BACKCOLOR
cf2.dwEffects = 0
cf2.crBackColor = RGB(255, 0, 0)
SendMessage RichTextBox1.hWnd, EM_SETCHARFORMAT, SCF_SELECTION, cf2
End Sub
