[Lazarus] How to use data from stringlist in another form.
I have 2 forms, form 1 calls form 2 on a buttonclick process. Form 2 loads a string list, operations are carried out and the stringlist is saved. The application opens with form 1, data is produced and stored in a Tedit What I want to do is to compare the Tedit on form1 with data held in the stringlist of form2. The problem is that the stringlist is not yet created from the stringlist file. I have tried to load the stringlist from within form 1 but compilation fails with :- TestProj1.lpr(21,1) Error: Error while compiling resources. Compile with -vd for more details. Check for duplicates. The messaged produced using -vd did not indicate any duplicates and terminated the application with the same message. I'm sure this must be possible but with my limited knowledge, I can't see how.

How this started was because I wanted to write the content of my Memo to the clipboard and be able to paste it back in again, but I couldn't figure out how to do this in the linux version. Another thing how can I find out legal qualifiers i.e. Memo.Clear , Memo.Text (both illegal). What is legal?

Type Memo. then press ctrl-space, then identifier completion will show
you legal qualifiers.
I didn't fine .Lines.SaveToFile?
You can also go to the declaration of the tmemo (using alt-up) and see
the source code to inspect the properties/methods/functions but as
you'll see TMemo descends from TCustomMemo, probably inheriting some
properties etc, and the inheritance tree goes on up.
Finally, built in help is a nice aid: with your cursor on TMemo, press
F1 and you'll see properties and methods that are available.
I don't think my built in help is working, F1 does nothing.
How do I enable built in help?

Could one of you experts look at my code please.

The following is just a snipet.

end;
var
Form1: TForm1;
head : array [0..7] of string = ('Extra1', 'Extra2', 'Extra3',
'Extra4','Extra5', 'Extra6', 'Extra7', 'Extra8');
x : integer;
y : integer;
z : integer;
w : integer;
currentLength : integer;
collection : array of Detail;
information : array of array of string;
procedure TForm1.MenuItemInputClick(Sender: TObject);
//initial setup
begin
SetLength(collection,1);
SetLength(information,8,1);
end;
procedure TForm1.ButtonNextClick(Sender: TObject);
begin
// extend array lengths
if Length(collection) (y+1)then
begin
SetLength(collection, y+1);
SetLength(information[x],y+1);
end;
// load array
information[0,y] := TEdit1.Text;
information[1,y] := TEdit2.Text;
information[2,y] := TEdit3.Text;
information[3,y] := TEdit4.Text;
information[4,y] := TEdit5.Text;
information[5,y] := TEdit6.Text;
information[6,y] := TEdit7.Text;
information[7,y] := TEdit8.Text;
//display aray lenghts
z := (Length(collection));
LabelResult.Caption := inttostr(z);
w := (Length(information));
LabelResult1.Caption := inttostr(w);

After the first set of strings are added, I get this error message:-

I'm sure it's just me not understanding how arrays should be manipulated,

I know what I want to achieve with a gui program but not the best way to to complete an operation. Any pointers would be most welcome, Paul -- ---This message has been sent using Thunderbird on kubuntu--- -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
Re: [Lazarus] terminal window not displayed in lazarus on kubuntu linux

The problem: When I choose run, the program compiles just fine but the output is not displayed in a terminal window. This happens with all of my programs running on lazarus. I have the same lazarus, fpc and programs running on windows and on windows as soon as the program is compiled a terminal window pops up and displayed the results. From the 'Run' menu, select 'Run Parameters' and check 'Use Launching Application'. If Lazarus complains that it can't find the launching application, choose another from the combobox list snip Thank you for your reply Malcolm and leledumbo, The rub parameter for selection is:- /usr/bin/konsole -T 'Lazarus Run Output' -e $(LazarusDir)/tools/runwait.sh $(TargetCmdLine) If I select this and then run a program execution is stopped but the console window (from DeBug window-Terminal output) shows the following:- QDBusConnection: session D-Bus connection created before QCoreApplication. Application may misbehave. QDBusConnection: session D-Bus connection created before QCoreApplication. Application may misbehave. Fontconfig warning: /etc/fonts/conf.d/50-user.conf, line 9: reading configurations from ~/.fonts.conf is deprecated. If I don't check 'Use Launching Application' but have the debug console showing I get the following: [6n[H[m[H[2J9 9 2 2 8 5 4 3 5 10 3 4 6 8 6 8 8 1 3 2 10 5 6 4 1 3 10 4 5 8 9 10 1 3 8 10 6 1 0 5 1 5 8 5 4 4 5 9 1 3 2 [1BPlease Press Enter To Quit [1B This program should clear screen and generate random numbers but the [6n[H[m[H[2J and[1B seem to be control codes, also the console does not refresh. So as an example how can I check that a program is working correctly without having to run a final executable? If I './executable' it run and clears screen perfectly. I just can't see why the linux version will not work the same as the windows version. I hope all of the above is clear and look forward to any advise. regards Paul -- ---This message has been sent using Thunderbird on kubuntu--- -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
