'Nico' raised some bug with MS RichEdit Control (EditorGadget) when using it for plain text
It is MS bug not PB

Hello RASHAD

I have an error, on the END line 137

And i have not really understand what your code do

Posted: **Wed Sep 29, 2010 2:57 pm**

This code is to see a colored/formated text.

I will try fix it cause i use this in a VB6 application and I'm porting to PB.

Thank you very much.

Posted: **Wed Sep 29, 2010 3:38 pm**

Sorry KCC
I was and still very busy
- Open WoprdPad and write any formatted text with different font name,font size,font color
- Save the file as 'Test.rtf' in the same dir of this code

I was testing a bug with the scrollbar of the EditorGadget as 'Nico' mentioned
Beside now you can use RichEdit Control Ver 3.0 if you like to do that
And you can use Edit Control for Plain Text w/o any problem

Sorry again KCC

and have a good day sir

Posted: **Wed Sep 29, 2010 4:25 pm**

Code: Select all

PokeS(*MemoryBuffer, a.s, Len(a.s)+1,#PB_Ascii)  
     SendMessage_(HwndEditText1,#EM_REPLACESEL,0,PeekS(*MemoryBuffer ,Len(a.s)+1,#PB_Unicode))

This lines have a mismatch, first you call PokeS with #PB_Ascii flag and after you call PeekS with #PB_Unicode flag. Are you sure of that?

Hi Vitor

Compile the next code as Unicode
And do what you want to do with it and see the difference

Thanks for your explanation, and very good day to you

Posted: **Wed Sep 29, 2010 5:03 pm**

It works now, thanks.

I think what I need is more hard. I need add a line in the control with code only. Look my example on VB6:

Code: Select all

Public Sub AddMessages(RICHTEXT As Object, ByVal Color As Long, Message As String, Optional Bold As Boolean)
    With RICHTEXT
        .SelStart = Len(.Text) 'Move to end of RTB.
        .SelFontName = "Tahoma" 'Set font.
        .SelFontSize = 8.5 'Set font size.
        .SelBold = Bold
        .SelItalic = False
        .SelUnderline = False
        .SelColor = Color
        .SelText = Message & vbCrLf
    End With
End Sub

PB equivalent.

Well, the Bold, Italic I know how reproduce in that example, but the color is the problem.

This return only Chinese characters, how fix it?
Any Idea?
