（本文来源于图老师网站，更多请访问https://m.tulaoshi.com/bianchengyuyan/）把生成的HTML载入Webbrowser，生成网页表格 2procedure TFrmMain.loadHtml;var URL,v:OleVariant; HTMLDocument:ihtmldocument2;begin try makehtml; except on e:exception do //showmessage('出错！'+e.Message); //exit; end; HTMLDocument := (WebBrowser1.Document as IHTMLDocument2); v := VarArrayCreate([0, 0], varVariant); v[0] := htmlbody; // Here's your HTML string HTMLDocument.Write(PSafeArray(TVarData(v).VArray)); HTMLDocument.Close; end;
（本文来源于图老师网站，更多请访问https://m.tulaoshi.com/bianchengyuyan/）然后模拟点击网页的提交按钮，提交表单数据：表格 3procedure TFrmMain.submitForm;var obj:OleVariant; doc: ihtmldocument2;begin doc:=(WebBrowser1 .Document as IHTMLDocument2); if doc nil then begin //RichEdit1.text:=doc.body.innerText; obj:=doc.all.item('sub',0); obj.click; end;end;
设置代理服务器：表格 4function TFrmcheckproxy.ChangeProxy(const Proxy, Port,ByPass: string; const bEnabled: boolean = True): boolean;var reg: Tregistry; info: INTERNET_PROXY_INFO; Fproxy:string;begin Result := False; FProxy:=Format('%s:%s',[Proxy,Port]); reg := Tregistry.Create; try reg.RootKey := HKEY_CURRENT_USER; if reg.OpenKey('SoftwareMicrosoftWindowsCurrentVersionInternet Settings', True) then begin reg.Writestring('ProxyServer', Fproxy); reg.WriteInteger('ProxyEnable', integer(bEnabled)); info.dwAccessType := INTERNET_OPEN_TYPE_PROXY; info.lpszProxy := pchar(proxy); info.lpszProxyBypass := pchar(ByPass); InternetSetOption(nil, INTERNET_OPTION_PROXY, @info, SizeOf(Info)); InternetSetOption(nil, INTERNET_OPTION_SETTINGS_CHANGED, nil, 0);// InternetSetOption(nil, INTERNET_OPTION_REFRESH, nil, 0);// Sendmessage(HWND_BROADCAST, WM_SETTINGCHANGE, 0, 0); Result:=True; end finally reg.CloseKey; reg.free; end;end;
