سلام،

کامپوننت آماده‌اى سراغ ندارم. روش این است که فایل mpeg را بصورت BLOB ذخیره کنید و در هنگام نمایش آن را خوانده و در یک فایل موقت قرار دهید و آن فایل را با استفاده از ُکامپوننت MediaPlayer پخش کنید.

شما اگه فایلت رو از نوع Image تعریف کنی ، میتونی هر نوع فایلی رو داخلش ذخیره کنی
روش ذخیره هم که مثل باقلوا کدش ریخته تو اینترنت
فقط این رو توی گوگل جستجو کن
How To Save Image To Database in delphi

[یوسف زالی]

البته ماکروسافت توصیه می کنه از VarBinary استفاده کنید.

[benyaminrahimi]

برای ذخیره هر نوع فایل میشه از فایل استریم (varbinary) یا فیلد image در اس کیو ال استفاده کرد ... برای نمایش هم میتوان از کامپ.ننتی نظیر atviewer که خود مدیا پلیر رو در یک فرم کال میکنه استفاده کرد

همچنین من یه متد نوشتم که شما میتونید هر فایلی که برنامش در ویندوز نصب شده رو در یک فرم مثل پنل نشون بدید

http://segalpardaz.ir/wp-content/uploads/scan-and-showfile.jpg


function tpatern.showfileinobject(afile: string;
obj: TWinControl
): HWND;

var
forground: HWND;

hand: HWND;

begin

hand := 0;
forground := GetForegroundWindow;

patern.openfile(afile);

hand := GetForegroundWindow;

while (hand = forground) or (hand = 0) do
begin

hand := GetForegroundWindow;
sleep(100);
end;

Windows.SetParent(hand, obj.Handle);

SetWindowLong(Hand,

GWL_STYLE,
GetWindowLong(Hand, GWL_STYLE)
and not WS_CAPTION);

Result := hand;

end;

با سلام در خصوص پترن
tpatern
توضیح مختصر بدهید ممنون میشوم

[benyaminrahimi]

ببخشید او یه لایه از نرم افزار شما میتونید با shellexute جایگزین کنید .. معمولا ما کدهای مشترکمون رو تو لایه پترن مینویسیم

[fahimi]

ممنون از پاسخ شما
در خصوص ایجاد لایه پترن چیزی نمی دانم و جستجو در اینترنت هم چیزی دستگیرم نشد.
من مسیر فایل های از قبیل doc-pdf-jpg- و ... را ذخیره و در صورت نیاز با نرم افزار پیش فرض نمایش می دهم امکان این هست تمام فایل ها را که توسط سیستم عامل کاربر قابل نمایش است را درون فرم نرم افزار نمایش داد مانند تصویری در خصوص ورد انجام داده اید

[benyaminrahimi]

بله تمتم فرمت هایی که در ویندوز مصب شده اند رو نمایش میده
