Selecting delimited txt strings VB6

Specs: winxp pro, 800mhz Duron
I need help with selecting specific text in a richtextbox control in VB6.

What I originally wanted was a box with multiple paragraphs, each separated by two linefeed characters:

Dim strExample = "This is filler for the sake of this example, and serves to be nothing more than pretentious writing, solely for the purpose of being overly verbose and nonsensical; doing this proves to suit my purposes just fine." & vbCrLf & vbCrLf & _
"This second filler paragraph is to continue the train of thought with an unbroken, unfettered display of absolutely nothing, though slightly interesting and mildly entertaining nontheless."

RichTextBox1.Text = strExample

Now, I want to use the Click event to select all of the text in either of the two paragraphs, but not all text inside the entire richtextbox control:

Private Sub RichTextBox1_Click()
'not sure how to do it
'I was hoping someone would
'be able to help me
'thanks in advance
End Sub

Any ideas?
I have scoured the web for hours - and to no avail.

Use the VBSplit function.

dim Ar() as string

Ar = Split(strExample, vbCr)

Ar is an undefined array. Split defines it filling each element of the array with text between each vbCRlf. In this example every other element in the array will contain a Null string because there are two successive delimiters with nothing between them.

If that is unacceptable then use the Instr in conjunction with the Mid$ function to search for each successive vbCrLf. That takes a little more coding.

Thanks again (you helped me before with the wininet.dll)

It works great -

Also, what I ended up doing was:

strDelimiters = vbCrLf & vbCrLf
Arr() = Split(strExample, strDelimiters)

...which gives me the two elements I originally wanted.

Thanks again!

Oh, and by the way - here's another quick question:

How would I be able to click inside a richtextbox and select only a single paragraph in order to copy it to the clipboard?

I know I can drag the I-beam to select, but I want my prog to be more intuitive and easy to use.

I envision a richtextbox loaded with paragraphs and by clicking on one, it would be selected, leaving the rest unselected.

Is this an easy thing to impliment?

Good thinking Greg, putting the two CrLfs into a single string.

Selecting a whole paragraph with a single click could be a bit more difficult.

One way is to use the strings created with the Split function.

dim a as Integer
a = RTF1.Find(Arr(0), 0)

A will then contain the start location of the paragraph and the paragraph should be highlighted.
