He wants 2D dynamic arrays, let's give him one:
type
TMyArray = array of array of Float;
var
MyArray: TMyArray;
begin
SetLength(MyArray,Width,Height); // Valid index now:
[0..Width-1,0..Height-1]
// Do something with MyArray
// No deallocation needed, the compiler does this for you
end;
I'm still unable to build my libraries. Can I get anyone to help? :-)

Ah yes, you are correct. However the the Open returns the following
error:
"Query: Cannot open a non-select statement"
I also have found some more help in the Lazarus wiki which just happens
to have an example of how to do a "show tables". So then, I tried the
following:

I think "execsql" never returns any records, you supposed to use "open"
for queries returning results.
Execsql is for insert, delete, update, etc.

Hi,
I am trying to pre-fill a TComboBox with the all the tables in a

you can try

// alloc array
GetMem(YourArray, Width*Height*Sizeof(Float));

I went for this one. Excel 2.1 reading works nicely.
It also reads Excel 5
Hi,
I may have found a way top solve my problem (saving a list of components
from various places, not necesarely all nested in the top level
component / See below)
The question now is, how forward-compatible is this ode. How much do I
have to expect any of the current code to change in ways

Because it depends on the code page of the system you are using at the
moment you parse the char.

I know that all to well. :-) I made a ug
The problem with such function is that it requires a lot of data to be
used on a non ANSI table. and you can not use in a unicode
implementation the Char type, because a char can be more then one

Hi,
IsCharAlpha() is a Win32 API call. I'm trying to convert code that
uses that call, to be Windows and Linux compatible. Does FPC have a
cross-platform version of that API call? I did a text search through
the RTL of v2.2.3 and it only seems to have the Windows API version.
I can add a Linux
