record

So what will be the preferred way of initializing records? With a 'factory function': TMyRecord = record valueX: integer; valueY: integer; end; function MyRecord(const AValueX, AValueY: integer): TMyRecord; begin result.valueX := AValueX; result.valueY := AValueY; end; var myrec: TMyRecord; begin myrec := MyRecord(1, 2); end; or a constructor: TMyRecord = record valueX: integer; valueY: integer; constructor Create(const AValueX, AValueY: integer); end; constructor TMyRecord.Create(const AValueX, AValueY: integer); begin self.valueX := AValueX; self.valueY := AValueY; end; var myrec: TMyRecord;

given: -record(foo, {a, b, c}). I do something like this: Thing = #foo{a={1,2}, b={3,4}, c={5,6}}, Thing1 = Thing#foo{a={7,8}}. From a semantic view, Thing and Thing1 are unique entities. However, from a language implementation standpoint, making a full copy of Thing to generate Thing1 would be intensely wasteful. For example, if the record were a megabyte in size and I made a thousand "copies," each modifying a couple of bytes, I've just burned a gigabyte. If the internal structure kept track of a representation of the parent structure and each derivative marked up that parent in a way that

I wrote a scriptlanguage for my applications and my goal is to make it possible to publish any type from delphi in the script. I use rtti to automatize this task. For any instance type like classes I use the following code to find and call a method from script. var Info : TRttiType; Meth : TRttiMethod; Param : TArray<TValue>; Result : TValue; AnyClass : TClass; begin ... Info := RttiContext.GetType(AnyClass); Meth := Info.GetMethod('AMethod'); Setlength(Param, 1); Param[0] := TValue.From<Integer>(11); Result := Meth.Invoke(ClassInstance, Param); ... end; But with a record this code doesn't

I need users to record their voice on a browser and then automatically upload the resulting mp3 to a webserver. I am thinking the user presses a big fat start record/stop record button to do this. This would then save a file on the users hard disk. Then it would be efficiently compressed and automatically ftp'd up to a website. Is it possible to do this using ActiveX or perhaps Java? Or are there libraries available that help? The application is for users who can install software if need be so it will be possible to install exe's or whatever. Any suggestions are most appreciated. The ideal

I'm try to create application where user can record video from camera. One of the feature of this application must be a pause file recording. For example: User start record after pressing "Start" button. After some time user press "Pause" button and video recording paused. Then user press "Resume" button and video continue recording in the same file. Can any body help me? Thank you. WBR Maxim Set up an AVCaptureSession and a AVAssetWriter then you can switch the recording on an off with the boolean "isRecording". BOOL isRecording; -(void)captureOutput:(AVCaptureOutput *)captureOutput

This query works fine, WITH test AS ( SELECT array_agg(t) as x FROM ( SELECT 1111 as id, 'aaaaa' as cc ) AS t ) SELECT x[1] FROM test; but, can I access the recod elements? I try SELECT x[1].id ; SELECT x[1][1] ; ... nothing works. PS: with Google we see only OLD solutions... The context here is v9.X, no news about "array of record"? I try also select x[1] from (select array[row(1,2)] as x) as t; no solution to access only item 1 or only item 2. A clue that I was unable to follow: postgresql.1045698.n5.nabble.com solve the problem using a CREATE TYPE ... Ok, but I need "all in a query"

Is there a component or code that allows the following: Record a spoken word (or words) and save it/them to a file that can be played back. The file must be able to be played back on XP, Vista and Windows 7. The file can be either stand alone or saved to a datasource. [Using Delphi 7 for creating apps on XP and using Absolute Database.] The functions in MMSystem.pas let you do this using Windows API. You can either use high-level functions such as the MCI functions and PlaySound , or low-level functions such as waveInOpen , waveInPrepareHeader , waveInProc etc. If you want high control, you
