谁能给我一个和Windows资源管理器差不多的Delphi源码？

其实delphi做个windows资源管理器最简单，只需要将控件名中与Shell相关的几个控件添加进去，基本上就可以做出windows资源管理器的那种效果了。

比如Raize控件包中的三个控件：TRzShellCombo、RzShellTreeview、RzShellListView，再加个StatuBar、MainMenu，基本上就全了。

给大家提供几个常用的图象格式转换方法和其转换函数
希望可以对你有帮助
1. ICO图标转换BMP格式
2. 32x32 BMP格式图象转换为 ICO格式
3.转换BMP-JPEG文件格式
4.JPEG 转换为BMP函数
5.Bmp转换为JPEG文件格式函数
-------------------------------------------------------------------------------------------------------------------------
1.Chinese : ICO图标转换BMP格式
English :(Conversion from ICO to BMP)
--------------------------------------------------------

var
Icon : TIcon;
Bitmap : TBitmap;
begin
Icon := TIcon.Create;
Bitmap := TBitmap.Create;
Icon.LoadFromFile('c:picture.ico');
Bitmap.Width := Icon.Width;
Bitmap.Height := Icon.Height;
Bitmap.Canvas.Draw(0, 0, Icon );
Bitmap.SaveToFile('c:picture.bmp');
Icon.Free;
Bitmap.Free;
===================================
2.Chinese: 32x32 BMP格式图象转换为 ICO格式
English :32x32 bit Bitmaps to ICO's
-----------------------------------
unit main;

interface

uses

end;

end.

end;

--------------------------------------------------------------------
4.JPEG 转换为BMP函数

procedure Jpg2Bmp(const source,dest:string);

finally
bmp.free;
myjpeg.Free;
end;
end;

----------------------------------------------------------
5.Bmp转换为JPEG文件格式函数

procedure Bmp2Jpg(const source,dest:string;const scale:byte);
var
MyJpeg: TJpegImage;
Image1: TImage;
begin
Image1:= TImage.Create(application);
MyJpeg:= TJpegImage.Create;
try
Image1.Picture.Bitmap.LoadFromFile(source);
MyJpeg.Assign(Image1.Picture.Bitmap);
