Another essential reason to modify to solar technology may be the cost benefits it provides. Solar panel systems can handle generating electricity for businesses, reducing or eliminating the need for traditional resources of energy. This may end in significant savings on energy bills, particularly in areas with high energy costs. Furthermore, there are many government incentives and tax credits open to companies that adopt solar technology, which makes it a lot more cost-effective and affordable. The technology behind solar power is not at all hard, yet highly effective. Solar power panels are made of photovoltaic (PV) cells, which convert sunlight into electricity. This electricity can then be kept in batteries or fed directly into the electrical grid, with respect to the specific system design. So that you can maximize the advantages of solar power, it is vital to design a custom system this is certainly tailored to your unique energy needs and requirements. This may make sure that you have the best components in position, like the appropriate amount of solar panel systems plus the right form of batteries, to optimize your time efficiency and cost savings.

Amiguinhos, Sei que o tópico é antigo. Não sei se resolvido. Só para brincarem um pouco com CRUD e JSON. Usei Harbour e Fivewin, mas dá para adaptar.

Amiguinhos, Itamar M. Lins Jr. » 01 Sep 2026, 09:53 Olá! ... Então eu pergunto para quem usa. Como se faz para compilar um prg com o xHarbour ? Preciso de um exemplo. Eu ainda não me adaptei ao hbMake por preguiça, ainda uso .bat e com ele compilo testes usando as varias versões de Borland e Harbour/xHarbour passando como parâmetro quais eu quero. Mas assim só uso para .PRGs solitários. Estatísticas: Enviado por rochinha — 01 Out 2026 09:59

Amiguinhos, Só para lembrar que o xHarbour tem outra biblioteca. filemem Estatísticas: Enviado por rochinha — 01 Out 2026 09:48

Amiguinhos, Com harbour pódemos manipular via DOM tanto JSON como XML mas e HTML? Bom, com este pequeno exemplo de uso e minha classe MiniXPath você pode capturar IDs dentro de qualquer HTML e obter seu conteúdo. Para testar a classe o .PRG de teste fará a verificação da disponibilidade dos serviços NFC-e e EPEC diretamente da página do ambiente autorizador de São Paulo. Código: #include "FiveWin.ch"FUNCTION Main() local oXPath := TMiniXPath():New( "https://www.nfce.fazenda.sp.gov.br/NFCePortal/" ) if oXPath:Analisar() ? "NFC-e ................:", If( oXPath:lDisponibilidadeNFCe, "Disponivel", "Indisponivel" ) ? "Contingencia EPEC ....:", If( oXPath:lDisponibilidadeEPEC, "Disponivel", "Indisponivel" ) if oXPath:lDisponibilidadeNFCe MsgInfo( "Servico NFC-e OPERANTE" ) else MsgAlert( "Servico NFC-e INDISPONIVEL!" ) endif else MsgStop( "Erro na consulta: " + oXPath:cErro ) endifreturn NIL#include "TMiniXPath.class" Obtenha a classe diretamente em meu gitHub.

Amiguinhos, porter você já olhou o log do Apache, PHP ou MySQL para ver qual módulo não está subindo? Tente subir o MySQL pelo prompt. Uma coisa que pode causar a não inicialização do MySQL é corrompimento da pasta DATA. Renomei-a para _DATA, crie outra pasta e inicie o MySQL para ver se o mesmo sobe.
