delphi 调用帆软报表

Delphi是一个编程语言，帆软报表是一款企业级报表软件，可以通过调用帆软报表提供的API接口，在Delphi中嵌入帆软报表，实现报表的生成、查询和展示等功能。下面是一个简单的示例代码：

1. 在Delphi项目中添加以下两个单元：

unit UReportInterface;

interface

type

TReportInterface = class

public

class function ShowReport(const aReportFilePath: string): Boolean;

end;

implementation

uses

Winapi.Windows, Winapi.ShellAPI, System.SysUtils;

class function TReportInterface.ShowReport(const aReportFilePath: string): Boolean;

var

s: string;

begin

s := ExtractFilePath(Application.ExeName) + 'FR\' + aReportFilePath;

if FileExists(s) then

begin

ShellExecute(0, nil, PChar(s), nil, nil, SW_SHOWNORMAL);

Result := True;

end

else

begin

Result := False;

end;

end;

end.

unit UMainForm;

interface

uses

Winapi.Windows, Winapi.Messages, System.SysUtils, System.Variants,

System.Classes, Vcl.Graphics,

Vcl.Controls, Vcl.Forms, Vcl.Dialogs, Vcl.StdCtrls, UReportInterface;

type

TForm1 = class(TForm)

Button1: TButton;

procedure Button1Click(Sender: TObject);

private

{ Private declarations }

public

{ Public declarations }

end;

var

Form1: TForm1;

implementation

{$R *.dfm}

procedure TForm1.Button1Click(Sender: TObject);

begin

TReportInterface.ShowReport('Report1.frf');

end;

end.

2. 在项目中添加一个按钮，单击事件中调用ShowReport方法即可。
