Да я понимаю к чему ты клонишь но символы должны быть разные для каждого edit ! Несколько функций объявлять тоже не хочется
Нет, не понимаешь. PHP: CheckSym('Символы для первого Edit', Edit1.Text);...CheckSym('Символы для второго Edit', Edit2.Text);...CheckSym('Символы для третьего Edit', Edit3.Text);
Подскажите где ошибка? при выборе камеры в ComboBox , выдает ошибку... код: Code: var Form1: TForm1; VideoDevice: TSysDevEnum; AudioDevice: TSysDevEnum ; implementation {$R *.dfm} procedure TForm1.FormCreate(Sender: TObject); var i,j: integer; begin VideoDevice:= TSysDevEnum.Create(CLSID_VideoInputDeviceCategory); AudioDevice:= TSysDevEnum.Create(CLSID_CWaveinClassManager); if VideoDevice.CountFilters > 0 then for i := 0 to VideoDevice.CountFilters - 1 do ComboBox1.Items.Add(VideoDevice.Filters[i].FriendlyName); if AudioDevice.CountFilters > 0 then for j := 0 to AudioDevice.CountFilters - 1 do ComboBox2.Items.Add(AudioDevice.Filters[j].FriendlyName); end; {-----------------------------------------} procedure TForm1.ComboBox1Change(Sender: TObject); begin FilterGraph.ClearGraph; FilterGraph.Active := false; Filter1.BaseFilter.Moniker := VideoDevice.GetMoniker(ComboBox1.ItemIndex); FilterGraph.Active := true; with FilterGraph as ICaptureGraphBuilder2 do RenderStream(@PIN_CATEGORY_PREVIEW, nil, Filter1 as IBaseFilter, SampleGrabber1 as IBaseFilter, VideoWindow1 as IbaseFilter); FilterGraph.Play; ButtonStopPlay.Enabled:=True; end; вроде все правильно сделал или сам компонент DSPack не поддерживает мою камеру?
Ты привел кодес заполнения комбобоксов, но не выбора камеры. Покажи какой у тебя там ивент (OnChange, OnClick) или может по нажатию на кнопке.
Code: procedure TForm1.ComboBox1Change(Sender: TObject); begin FilterGraph.ClearGraph; FilterGraph.Active := false; Filter1.BaseFilter.Moniker := VideoDevice.GetMoniker(ComboBox1.ItemIndex); FilterGraph.Active := true; with FilterGraph as ICaptureGraphBuilder2 do RenderStream(@PIN_CATEGORY_PREVIEW, nil, Filter1 as IBaseFilter, SampleGrabber1 as IBaseFilter, VideoWindow1 as IbaseFilter); FilterGraph.Play; end;
Попробуй так: PHP: RenderStream(@PIN_CATEGORY_PREVIEW, @MEDIATYPE_Video, Filter1 as IBaseFilter, SampleGrabber1 as IBaseFilter, VideoWindow1 as IbaseFilter); У тебя точно в FilterGraph.RenderStream косяк, нужно только правильные аргументы передать.
Блин, ну тогда надо открывать делфи, а под рукой ее нету. Завтра если не забуду, постараюсь посмотреть)

вопрос как спарсить users?!
Специально для тебя) Code: function getBetween(src: String; a: String; b: String): String; var p: Integer; begin p:=Pos(a, src)+Length(a); Result:=Copy(src, p, PosEx(b, src, p)-p); end; и юзаешь Code: строкаДляЮзеровЧерезЗапятую:=getBetween(str, '"users":[', ']'); Где в str у тебя этот json. Дальше в массив, если надо, сам. Думаю, в гугле есть ответ
Здравствуйте собственно такой вопрос: как определить какие именно Checkbox выбраны у меня их три checkbox1, checkbox2, checkbox3?
Нет это итак понятно как сделать чтобы не писать PHP: checkbox1.Checked, checkbox2.Checked, checkbox3.checked ? checkbox[i].Checked ошибка
Это где вас так учили к компонентам обращаться? PHP: var e: TCheckBox; cbName: string; i: integer;begin Memo1.Clear; cbName:='CheckBox'; for i:= 1 to 3 do begin e := (FindComponent(cbName+IntToStr(i)) as TCheckBox); if (e <> nil) and (e.Checked) Then Memo1.Lines.Add('CheckBox'+inttostr(i)+' checked') Else Memo1.Lines.Add('CheckBox'+inttostr(i)+' NOT checked') end;end;
Считаю следующий вариант более правильным: Code: for i:=0 to ComponentsCount-1 do begin if (Components[i] is TCheckBox) then begin if (Components[i] as TCheckBox).Checked then Memo1.Lines.Add((Components[i] as TCheckBox).Name+' is checked') else Memo1.Lines.Add((Components[i] as TCheckBox).Name+' is not checked'); end; {if} end; {for} Это если компоненты сразу на форме. Если, например, на панели, то обращаться как Panel1.ComponentsCount и Panel1.Components, например
