Generate Ordered Numbers (Starting at a Specified #)

Posted on 2006-06-20

Hello All;
This is a bit of an "Must Have" issue.

I need to have a function that will Generate Numbers from a {Starting # that I specify} into the beginning of every line in a RichEdit.
For Example: (Have a TEdit, to allow for Starting Number Insertion)

Line line line line
Line line line line
Line line line line

In this example, I need to start the Number out at: [6] so it would be something like this
6 Line line line line
6 Line line line line
6 Line line line line

Please someone, have any idea's on this one?

do you mean something like

6 line line line
7 line line line
8 line line line

I take it you already know how to insert text into a richedit? using SelPos, and SelText?

So what you need to do is determine what line number you want to start on, and then seek the endofline and insert the text.
Are you also wanting to remove numbers from the richedit if you call the routine again with a different starting number?

What control specifically do you want to do this with, Tedit, or TRichEdit? it makes a difference

var
s, i : integer;
begin
s := 10;
for i := 0 to RichEdit1.Lines.Count - 1 do
RichEdit1.Lines.Strings[i] := inttostr(s + i) + RichEdit1.Lines.Strings[i];
end;

If you dont want to increment the starting number then

var
s, i : integer;
begin
s := 10; // your starting number
for i := 0 to RichEdit1.Lines.Count - 1 do
RichEdit1.Lines.Strings[i] := inttostr(s) + RichEdit1.Lines.Strings[i];
end;

Yes Harris
6 line line line
7 line line line
8 line line line
That is what I meant. Sorry about that, was 1/2 a sleep while writing it.

Atul, I will get back with you sometime after while if this code is what I need.
The one thing that I do not see in either of the codes that you have supplied here
Is a way to manually change the beginning #, like a Edit1.text...

Thanks a bunch guys

Harris.
The Starting # would be a TEdit
The lines are contained in a TRichEdit.
(If that is what you are asking about)
And no, I will not be having to Remove the Numbers.
This will be used as a 1-time thing.

Thanks

Sorry Atul.
I think that I goofed at the beginning of the post.
And you probably have not read my comment that cleared up my mistake.

I need the numbers to be like so:

Line line line line
Line line line line
Line line line line

In this example, I need to start the Number out at: [6] so it would be something like this
6 Line line line line
7 Line line line line
8 Line line line line

They need the numbers to be Ordered, (NOT) Rambom, and not just 1-single #

Sorry about the confusement.
I was 1/2 a sleep, when I wrote the starting of this Post/Question.

var
s, i : integer;
begin
s := StrToInt(Edit1.Text);
for i := 0 to RichEdit1.Lines.Count - 1 do
RichEdit1.Lines.Strings[i] := inttostr(s + i) + RichEdit1.Lines.Strings[i];
end;

If you are using D7 above, use TryStrToInt instead of StrToInt function.

var
s, i, code : integer;
begin

// first check that you have a valid integer to work with
val( Trim(edit1.text), i, code)
if code = 0 then
s := i
else
exit;

// now loop
for i := 0 to RichEdit1.Lines.Count - 1 do
RichEdit1.Lines.Strings[i] := inttostr(s + i) + RichEdit1.Lines.Strings[i];
end;
