前期准备：uses Vcl.Themes, Vcl.WinXCtrls;procedure TForm1.ComboBox1Change(Sender: TObject);beginTStyleManager.SetStyle(ComboBox1.Text);end;procedure TForm1.FormCreate(Sender: TObject);varStyleName: string;begin for StyleName in TStyleManager.StyleNames do
GIF 动画建立var Gif:TGifImage;begin //Setting the delay for each frame TGIFGraphicControlExtension.Create(Gif.Add(image1.Picture.Bitmap)).Delay := 300; TGIFGraphicControlExtension.Create(Gif.Add(image2.Picture.Bitmap)).Delay := 300; TGIFGraphicCo
procedure TForm2.Button1Click(Sender: TObject);var StrLst:TStringList;begin StrLst:=TStringList.Create; StrLst.LoadFromFile('D:\text.txt'); ShowMessage(StrLst[StrLst.Count-1]); StrLst.Free;end;
在Form上放一个ADOConnection,连结指向目标Access库比如txt文件在c:\temp\aaaa.txt就执行ADOConnection.Connected := True;ADOConnection.Execute(’Select * Into abcd From [Text;Database=c:\temp].aaaa.txt’);方法2：procedure TForm1.btnimporttextClick(Sender: TObject);var TextFileVar: Tex
一、遍历 TStringsvar List: TStrings; s: string;begin List := TStringList.Create; List.CommaText := 'aaa,bbb,ccc'; for s in List do ShowMessage(s); List.Free;end;二、遍历数组var Arr: array[0..2] of Byte; i: Integer; b: Byte;begin for i := Low(A
