Hi trying test , I wish to attain a layout of image inside a DBCtrlGrid an hope to use the AysncMode of the imageEn.IO to load pictures in the background in Delphi 6, However I am having problems with this the picture loads as expected however when you close the app it freezed about 1 minute most of the time the form becomes white and unresponsive,. bellow is the goal I wish to attain layout
P.S. it doesn't need to be the exact effects but all i want is an image and can be some text overlay, the shadow and the rounded mask can be ignored this is only an idea
I need to put captions for product names and prices also and bellow here's my test code, the ImageEnView was placed inside the DBCtrlGrid for it to iterate.
object Form1: TForm1
Left = 192
Top = 107
Width = 696
Height = 480
Caption = 'Form1'
Color = clBtnFace
Font.Charset = DEFAULT_CHARSET
Font.Color = clWindowText
Font.Height = -11
Font.Name = 'MS Sans Serif'
Font.Style = []
OldCreateOrder = False
OnShow = FormShow
PixelsPerInch = 96
TextHeight = 13
object DBCtrlGrid1: TDBCtrlGrid
Left = 16
Top = 16
Width = 665
Height = 417
ColCount = 5
PanelHeight = 139
PanelWidth = 129
TabOrder = 0
RowCount = 3
OnPaintPanel = DBCtrlGrid1PaintPanel
object ImageEnView1: TImageEnView
Left = 8
Top = 8
Width = 114
Height = 124
ParentCtl3D = False
ImageEnVersion = '3.1.2'
EnableInteractionHints = True
TabOrder = 0
end
end
object ADOQuery1: TADOQuery
Parameters = <>
Left = 232
Top = 104
end
end
unit Unit1;
interface
uses
Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
Dialogs, ieview, imageenview, dbcgrids, DB, ADODB;
type
TForm1 = class(TForm)
DBCtrlGrid1: TDBCtrlGrid;
ImageEnView1: TImageEnView;
ADOQuery1: TADOQuery;
procedure DBCtrlGrid1PaintPanel(DBCtrlGrid: TDBCtrlGrid;
Index: Integer);
procedure FormShow(Sender: TObject);
private
{ Private declarations }
public
{ Public declarations }
end;
var
Form1: TForm1;
implementation
{$R *.dfm}
procedure TForm1.DBCtrlGrid1PaintPanel(DBCtrlGrid: TDBCtrlGrid;
Index: Integer);
begin
ImageEnView1.IO.AsyncMode := True;
ImageEnView1.IO.LoadFromURL('http://www.example.com/'+ADOQuery1.fieldbyName('pic_file').AsString+'.jpg');
end;
procedure TForm1.FormShow(Sender: TObject);
begin
ADOQuery1.Close;
ADOQuery1.Open;
end;
end.
Can this be possible? or am i using the wrong components to achieve this? the pictures will be in a central network, I wish to use the multi-thread loading because if not the program most of the time hangs when getting many pictures from the server.
