Good afternoon. Help, people of goodness!
There's a Delphi program, the results of her work, she keeps it in the format file. pdf (this is done with help doPdf of MSWord) Can there be some software contact with the window? doPdfwhich requests retention? It's just that the program doesn't ask for the name of the remaining file, and it's automatic... I'll be happy with any advice. Thank you.

If press calls are synchronized, there is no other solution to use the additional flow into the head.

To be able to perform the iteration on the "brother" you must recover the valueitem := item.NextSibling; By doing this, item recovers the value of the next node. With this you get the next nodes. But please note that at the end item will not be assigned when there are no more nodes. So in the loop you have to make sure it is assigned. It would be like this:while assigned(item) and (item.NodeName = 'channel') do begin id := item.Attributes['id']; //¿No habría que hacer algo on id? item := item.NextSibling; end; I hope it serves you.

Another alternative, native from Delphi 2009 or higher, is the function http://docwiki.embarcadero.com/VCL/2010/en/SysUtils.ByteLength the unit SysUtils.Here's an example (retreat of documentation):var LS1: WideString; begin LS1 := 'Hello World!'; Writeln('UnicodeString: ''', LS1, ''' contains ', Length(LS1), ' characters in ', ByteLength(LS1), ' bytes.'); Readln; end. The output will be: How well https://pt.stackoverflow.com/questions/10517/como-saber-o-tamanho-em-kb-de-uma-string/10740#comment18452_10740 function ByteLength is not available for versions lower than Delphi 2009, looking at the function source code ByteLength it is possible to see that it is essentially the same code posted https://pt.stackoverflow.com/a/10624/6454 .Code:function ByteLength(const S: string): Integer; begin Result := Length(S) * SizeOf(Char); end;

I work with you. docker Windows 8. We've got a lot of projects. Vagrant and VirtualBoxAnd recently we've moved on. docker♪ I read somewhere that VirtualBox doesn't live with Hyper-V, so we use it. Docker Toolbox and VirtualBoxTo start working after installation Docker Toolbox and VirtualBoxWe need to take a few steps.Create Docker Machinedocker-machine create --driver virtualbox default docker-machine start default Build Docker MachineMaintenance of team performance docker-machine env default in variable environments (computer properties)C:\>docker-machine env default You can further specify your shell with either 'cmd' or 'powershell' with the --shell flag. SET DOCKER_TLS_VERIFY=1 SET DOCKER_HOST=tcp://192.168.99.100:2376 SET DOCKER_CERT_PATH=C:\Users\Пользователь.docker\machine\machines\default SET DOCKER_MACHINE_NAME=default SET COMPOSE_CONVERT_WINDOWS_PATHS=true REM Run this command to configure your shell: REM @FOR /f "tokens=*" %i IN ('"C:\Program Files\Docker Toolbox\docker-machine.EXE" env default') DO @%i For example, there are five variables from DOCKER_TLS_VERIFY before COMPOSE_CONVERT_WINDOWS_PATHSOptical: add the record to the file C:\WINDOWS\System32\Drivers\etc\hosts (sighs)192.168.99.100 - this is the IP address from the variable. DOCKER_HOST)192.168.99.100 docker.local That's it. You can start working = And linux doesn't need a system, you've got a little misunderstanding, and the system will spin inside. dockerYou can start with a simple file. docker-compose.ymlversion: "2.1" services: nginx: image: nginx:latest ports: - "80:80" It's necessary to create it in the user folder, for example, C:\Users\Пользователь\Docker\Qwerty♪ More specifically, it needs to be done in projects where host files should be accessible inside the container, this is not a requirement in this example.In the file with the file. docker-compose.yml Starting the team. docker-compose up -d We're going in. http://docker.local/ ♪ There'll be a default page. NginxTips & Tricks: Sometimes it's like there's no Internet inside the container. Then we need to stop first. docker-machine stopAnd then start over docker-machine startYou can go for a google. docker-compose nginx php mysql

After searching a lot (3 days!) I ended up discovering the solution along with a coworker. Below is an example of the solution implemented within a onClick and a buttonprocedure TForm1.Button1Click(Sender: TObject); var contexto: TRttiContext; TypObj: TRttiType; Prop: TRttiProperty; SubProp: TRttiProperty; obj: TObjeto; begin obj:= TObjeto.Create; contexto:= TRttiContext.Create.Create; TypObj:= contexto.GetType(obj.ClassInfo); Prop:= TypObj.GetProperty('P1'); SubProp:= Prop.PropertyType.GetProperty('S'); ShowMessage(SubProp.GetValue(Prop.GetValue(obj).AsObject).ToString); end;

How exactly are you running the program? (I can't leave a comment because I don't have enough score).First you should make sure that the Python installation is ok on your running machine python --version in your terminal. If you show the right version, it is pq is ok. If you do not recognize the command you must redo the installation.Once the installation is correct, run the command python, this will put you inside the Python interpreter. There you can run multiple commands individually, including print("Hello, world!").To run a program you have in a file, run the command in the terminal python nomeDoArQuivo. Make sure that the file has .py extension, and that you are running the command in the same directory where the file is located. I hope I helped.

Maybe it's just that URL doesn't find anything? For example, you've got references like http://www.... and you're transmitting a "www...." Try not to follow the code but directly through the Engine/Server explorer Database.

Hey, thanks for the answers if you're right. What's going on is, I haven't cooked anything. And I don't think my order is understood. I'm not going for the subject that helps me codify something. I was just asking for suggestions that I can prove. For example as the links you leave. Where you can suggest me, try this bookstore. Framework. Plugins etc. To review and be able to try to replicate the demo or idea you leave where you should start. Just indicate you could prove it. Not so much help encoding.I hope you understandGreetings

Wake the socks until it's working.Read about building a client-serious system. Look, the server should have a white IP address so you can connect to him with a client.Learn how the p2p system works.In any case, you'll be using sockets for data transmission/acceptance.
