这个dll调用该怎么释放？
我写了一个dll，封装了几个窗口，窗口之间有调度操作，
应用部分：

Delphi(Pascal) code

procedure TForm1.Button1Click(Sender: TObject);typeTFunc=procedure;stdcall;varTh:Thandle;Tf:TFunc;beginTh:=LoadLibrary('ReStore.dll'); {装载DLL}if Th>0then begin     try       @Tf:=GetProcAddress(Th,PChar('createform'));       if @Tf<>nil       then tf       else ShowMessage('createform函数没有找到');     finally      FreeLibrary(Th);     end;     endelse ShowMessage('ReStore.dll没有找到');end;

DLL定义：

Delphi(Pascal) code

uses  SysUtils,  Classes,  AdminRestoreDBSelectDB in 'AdminRestoreDBSelectDB.pas' {AdminRestoreDBSelectDBForm},  AdminDeleteDB in 'AdminDeleteDB.pas' {AdminDeleteDBForm},  AdminRestoreDB in 'AdminRestoreDB.pas' {AdminRestoreDBForm};  procedure createform;stdcall;  begin  AdminRestoreDBForm:=TAdminRestoreDBForm.Create(nil);  AdminRestoreDBForm.ShowModal;  end;{$R *.res}exports createform;beginend.

因为调用dll后马上释放了dll，所以关闭dll的打开窗口后会抛出错误，但如果不在try...finally里释放dll，又该怎么执行FreeLibrary()呢？

[解决办法]
DLL里建FORM时,使用模式显示,即Showmodal;
