怎样动态调用DLL?

[regft]

library Project1;

{ Important note about DLL memory management: ShareMem must be the
first unit in your library's USES clause AND your project's (select
Project-View Source) USES clause if your DLL exports any procedures or
functions that pass strings as parameters or function results. This
applies to all strings passed to and from your DLL--even those that
are nested in records and classes. ShareMem is the interface unit to
the BORLNDMM.DLL shared memory manager, which must be deployed along
with your DLL. To avoid using BORLNDMM.DLL, pass string information
using PChar or ShortString parameters. }

uses
SysUtils,
Classes,
forms,
Unit1 in 'Unit1.pas' {Form1};

{$R *.res}
procedure LoadFormxp(AppHandle:THandle);stdcall;
begin
Application.Handle:=AppHandle;
Form1:=TForm1.Create(Application);
Form1.Show;
end;

procedure UnFormxp();stdcall;
begin
if Assigned(Form1) then
FreeAndNil(Form1);
end;
exports
LoadFormxp,
UnFormxp;

begin
end.


请大家帮助,怎样动态调用DLL?

我也记不到了。给你个例子吧：
procedure test;
const
　ADllName='D:\dll\Project2.dll';
　AProcName='DoTest';
var
　Lib:Integer;
　AProc:procedure (H: THandle;AConn: TADOConnection); cdecl;
begin
try
　　Lib:=LoadLibrary(PChar(ADllName));
　　if Lib<>0 then
　　try
　　　AProc:=GetProcAddress(Lib,PChar(AProcName));
　　　if @AProc=nil then
　　　begin
　　　　MessageBox(Handle,Format('动态链接库"%s"中找不到过程"%s"的入口地址!',[ADllName,AProcName]),'错误','MB_ICONERROR);
　　　　Exit;
　　　end;
　　　AProc(Application.Handle,ADOConnection1);
　　finally
　　　FreeLibrary(Lib);
　　end else
　　　MessageBox(Handle,Format('找不到动态链接库"%s"',[ADllName]),'错误',MB_ICONERROR);
　except
　　on E:Exception do
　　MessageBox(Handle,PChar('不明错误!错误信息为:'+E.Message),'错误',MB_ICONERROR);
　end;
end;

三个API函数:
LoadLibrary()
GetProcAddress()
FreeLibrary()

有详细的吗?
