Re: [Lazarus] Component compilation problem with lazarus 2.2

Sorry, I also allocate the complete file
Hello to all,
This code compiles with lazarus 2.0.12
constructor TExtTabPanel.Create(AOwner : TComponent);
begin
{$IFDEF LCL}
ￜￜ PageClass := TExtPanel_Tab;
{$ENDIF}
ￜ inherited Create(AOwner);
ￜ Disabled := False;
ￜ Hidden := False;
end;ￜ
but with lazarus 2.2 it gives me the following error:
*extp_design_ctrls.pas(1247,4) Error: Identifier not found "PageClass"*
How do I resolve?
Remove the {$ifdef}...{$endif} altogether.
The reference to "PageClass" is presumably some leftover from earlier
code. It is not needed.

Re: [Lazarus] How to get space before auto-inserted assignment?

Re: [Lazarus] Feedback Wanted: Next tutoring project
On 06/05/2019 01:32, Anthony Walter via lazarus wrote: Regarding the next project, I think I am going to concentrate two different programming tasks for my students. One task is to create various tones through simple functions, and the other is to create effects (again through simple functions) which manipulate a sound source. Examples of effects might include a chorus effect, pan effect, flanger effect, reverb effect, echo effect, and probably a few crazy original sounding effects that don't make much sense for musicians to use. In any case, I suspect that I will allow the user to again hook effects up together in a chain, possibly using the same node type user interface where one effect outputs samples that can be fed into other effects. And in place of the image drawn above like in the Image Shop example, I might just make the rendering take the shape of graphing real time wave forms and cut back slightly on the musical staff, at least until another point in time. As well as effects to alter the tones, you could consider adding a repetitive mode in which beats/rhythm is introduced for one or more tones, such as various drumming styles, pizzicato, rock rhythms, hip hop, waltz and other dance beats etc. If the tones sounded concurrently this could add a ground bass effect. -- ___ lazarus mailing list lazarus@lists.lazarus-ide.org https://lists.lazarus-ide.org/listinfo/lazarus

Re: [Lazarus] Converting all code to use UnicodeString

I understood that I can use like this:

Not like this:

Right?
But this is not compile:
const
V1: string = 'a';
V2: string = V1 + 'b';
You can't do that in a const declaration.
But in an implementation, the following does compile:
{$J+} {$H+}
const
V1: string = 'a';
V2: string = 'b';
V3: String = '';
begin
V3:=V1 + V2;

Re: [Lazarus] Writing >1000 TBufDataset records to file is extremely slow
On 26/03/17 22:53, Werner Pamler via Lazarus wrote: Trying to extend the import/export example of fpspreadsheet from a dBase table to a TBufDataset I came across this issue with TBufDataset: While data are posted to the database as quickly as usual writing to file takes extremely long if there are more than a few thousand records. Run the demo attached below. On my system, I measure these (non-linearly scaling) execution times for writing the TBufDataset table to file: 1000 records -- 0.9 seconds 2000 records -- 8.8 seconds 3000 records -- 31.1 seconds etc. Compared to that, writing of the same data to a dbf file is a wink of an eye. Is there anything which I am doing wrong? Or should I report a bug? I don't think you do anything wrong. I can get small performance increases by - avoiding FieldByName() calls and using AppendRecord - using SaveToFile and avoiding an intermediate memory stream - increasing the value of PacketRecords but the speedups are insignificant. Clearly either the insertion algorithm should be improved, or the buffering, or the way the buffered records are written to disk. Maybe all three areas of TBufDataset can be optimised for better performance. -- ___ Lazarus mailing list Lazarus@lists.lazarus-ide.org http://lists.lazarus-ide.org/listinfo/lazarus
