Hi all,

Is it possible to highlight code in a richtextbox in the same way as in the SQL Query analyzer?
I've looked in MSDN, and I think it's feasable, but I really didn't find how to do that.

Thanks for the help

Here is a very basic example of hightlighting in a rich text box

rText.Text = "Don't highlight, highlight"
   
rText.SelStart = 17
rText.SelLength = 9


Hope it helps.

Note, There are other properties that set attribs. for the selected text such as Color, bold, etc...  They all begin with Sel (SelColor) in the properties of the Rich text box.

I know how to higlight, thanks.
I meant the SQL highlighting format.
eg: when you write "exec", it automatically turns to blue...

SQL syntax in higlighted in different colors.
Is this possible?

Thanks

Do you mean that you want to use an RTB with SQL code and highlight it as SQL would? If so then I can certainly help here as I was involved in another thread that did exactly this a while ago.

Ok, just found it:

Add a textbox and a richtextbox on the form, add a reference to Microsoft SQL Parser Object Library 1.0 (SQLPARSE.DLL in \program files\microsoft office\office\ folder) Then run the application and start typing in the text box, the RTB should display the correctly highlighted SQL code.

Private Sub WriteToRTF(ByRef RTBox As RichTextBox, ByVal Statement As String)
    Dim intElement As Long
    RTBox.Text = ""
    Dim aryElements() As String
    aryElements = Split(Statement, "\cf ")
    For intElement = LBound(aryElements) To UBound(aryElements)
        If Trim(aryElements(intElement)) <> "" Then
'            If aryElements(intElement) = String(Len(aryElements(intElement)), " ") Then
'                RTBox.Text = RTBox.Text & aryElements(intElement)
'            Else
                strContent = Mid(Trim(aryElements(intElement)), 6, Len(Trim(aryElements(intElement))) - 5)
                With RTBox
                    .Text = .Text & String(Len(aryElements(intElement)) - Len(strContent) - 5, " ")
                    .Text = .Text & strContent
                    .SelStart = Len(.Text) - Len(strContent)
                    .SelLength = Len(strContent)
'                    Debug.Print .SelStart, .SelLength, strContent
                    Select Case Mid(Trim(aryElements(intElement)), 4, 2)
                    Case "1 "
                        'Keyword
                        .SelColor = vbBlue
                    Case "3 "
                        'System Function
                        .SelColor = vbGreen
                    Case "5 "
                        'Operator
                        .SelColor = RGB(75, 75, 75)
                    Case "6 "
                        'Text
                        .SelColor = vbRed
                    Case "7 "
                        'Number
                        .SelColor = vbCyan
                    Case "8 "
                        'Comment
                        .SelColor = vbMagenta
                    Case "10"
                        'Standard Text
                        .SelColor = vbBlack
                    Case Else '2, 4, 9
                    End Select
                End With
'            End If
        End If
    Next
End Sub

Private Sub Text1_Change()
    ParseContent Text1.Text
End Sub

Private Sub ParseContent(ByVal SQL As String)
   Dim osQL As MSSQLParser.vbSQLParser
   Dim sTemp As String
   Set osQL = New MSSQLParser.vbSQLParser
   sTemp = osQL.ParseSQLSyntax(SQL, vbSqlServerSyntax)
   WriteToRTF RichTextBox1, sTemp
   Debug.Print sTemp
   Set osQL = Nothing
End Sub
