TMemo....help needed

[jshand2010]

hi guys.  just wondering how to get the total nukber of lines in your memo box.  please let me know.  i have tried tmemo.lines.....that doesn't work.

YourMemo.Lines.Count

[Avishai]

I think it's Memo1.Lines.Count

[jshand2010]

thanks for your help

i have place in the meinformationChange procedure this code:

g := meinformation.Lines.Count;

i am unsure if this is working as yet;

the following i have coded in the same procedure:

for d := 1 to g do
  begin
      sm[d].information := meinformation.Lines[d];
 end;

this doesn't seem to work.  please help me.  also loading into the memo box is proving difficult for me as i have little knowledge for this control.

thanks again

this doesn't seem to work. 

Based on what? Debugger output?

Lines in a memo are numbered from 0.. Count-1.

Code: Pascal  [Select][+][-]

1. g := meinformation.Lines.Count;
2. //...
3. for d := 0 to g-1 do
4.   begin
5.      // sm[d].information := meinformation.Lines[d];  <-- WHAT IS smd[d]?
6.  end;

hi there
sm[d].information is an array of strings.

hi there
sm[d].information is an array of strings.

Please post the type definitions.

[jshand2010]

hi eny, below are the type definitions you asked for

type
  StaffMemo = record
    information: string;
  end;

under vars is:

sm: array[1..1000000] of StaffMemo;

[fabienwang]

by doing, array[1..1000000], you will take a lot of memory space at the declaration.
as you won't use all of them, i suggest you to define the array dynamically,
m: array of StaffMemo;

maintain a global counter: nbsm: Integer;
and each time you want to add lines into it:
Inc(nbsm);
setLength(sm, nbsm);

Alrighty, now what is that you wish to accomplisch?
Because your initial question has already been answered.

(As FabienWang said, you have defined a rather big static array...)

[liewald]

Why are you copying the Memo to an array of strings? Memo.lines is essentially a dynamic array of strings anyway with some extra handling built in.  Any line can be accessed using memo1.lines

• like any normal array. I don’t really understand what you are trying to achieve here.

I don’t really understand what you are trying to achieve here.

Hence my question...
