Hello,
     Can I use rich text box to display and print reports. My problem is I don't know how to add text to RTF Box at runtime using different fonts and colors at a particular line.

     For example, If I do something like this:
       
     rtf.Font.Size = 15
        rtf.Text = "Hello"
        rtf.Font.Name = "Arial"
        rtf.Font.Size = 20
        rtf.Text = rtf.Text & " How"
     
     Then both words are displayed using Size 20 and font arial. But I wanted that only second word should be of size 20 and font "Arial".
     
     Also If I want to move to a particular line and then move to a column n and start writing text at column n. So is there any way to do it?

Check this,

    RichTextBox1.Text = "text stuff*color me blue*textstuff*color me blue*text stuff*blue*text*blue*text"
   
    Marcfindit = "*"
    Lengther = Len(Marcfindit)
    TotalLength = Len(RichTextBox1.Text)
   
   
    Start = 0
    Do Until Start >= TotalLength
      foundpos1 = RichTextBox1.Find(Marcfindit, Start, TotalLength, Text)
      If foundpos1 = -1 Then Exit Do
      If foundpos1 <> -1 Then 'asterisk found
          foundpos2 = RichTextBox1.Find(Marcfindit, foundpos1 + 1, TotalLength, Text)
            If foundpos2 = -1 Then Exit Do
            If foundpos2 <> -1 Then

                 RichTextBox1.SelStart = foundpos1
                 RichTextBox1.SelLength = foundpos2 - foundpos1 + 1
                 RichTextBox1.SelBold = True
                 RichTextBox1.SelColor = RGB(0, 0, 255)
               
                 Start = foundpos2 + 1  ' start looking here
            End If
         End If
    Loop
     
      RichTextBox1.SelStart = 0
      RichTextBox1.SelBold = False
      RichTextBox1.SelColor = RGB(0, 0, 0)

Yes It works but * is visible. What else can be used in its place; space? Also you have added all text before changing font color etc. I want to retrieve record from a database and then display information contained in a record's fields one by one and line by line. If I use this method then for every field/row I add, I have to add a new invisible special character to identify that field/row which may not be possible. Also If there many lines then It wont look great on slow computers if text attributes change after displaying all text.

For example, If want to create a report to display employee records and I want that employee name should be Bold and centred, other fields should use different color, indentation etc. So, if I don't use this special character because it may not be used if there are 30-35 fields, I need a way to go a particular row and particular column and then write text there and change its colors etc. and then go to next row, write other information change text attributes and so on.

So main problem is going to a particular line/column, add more text and then change font etc of added text only.

Is there any way to achieve this?

Yes it was very close to my requirement. But I cannot add text to rtf directly but I have to retrieve records from database and then display them one field at a time. So I need a way where when I add more text, formatting of old text of rtf box doesn't change.

For example if I do rtf.text = rtf.text+"Hello" than I don't want that properties of text (fonts, colors etc)which is already there in rtf.text doesn't change.

Changing text attribute of text when text is entered directly into rtf box is simple.
But how can I achieve it when entering text through code at runtime?

>>But how can I achieve it when entering text through code at runtime?

The way to do this is to use code like that shown in from n_narayanan's example!  
1) Insert the text
2) Select it (programatically via SelStart and SelLength)
3) Then set the attributes (e.g. SelBold)

Richie_Simonetti, Right, you are!  However, I think that the "gentle hint" or the "mysterious ambiguity" is not going to go too far with this User.  indianmunda is needing some very specific answers.
