Delphi中DLL调用后如何完全释放
Delphi有静态加载Dll和动态加载Dll,静态加载的Dll不用我们释放;动态加载需要我们自己释放;
这里只附上动态加载DLL的释放(此处Dll和Exe程序在同一路径下):
procedure TForm1.Button2Click(Sender: TObject);
var MyHandle:THandle ;
FPointer:Pointer;
MyDll_Func: function (s:string):Integer;stdcall;
begin
try
try
MyHandle:=LoadLibrary('project1.Dll') ;
if MyHandle<>0 then
begin
FPointer:=GetProcAddress(MyHandle ,PChar(Edit1.text));
if FPointer<>nil then
begin
MyDll_Func:=FPointer;
MyDll_Func(Edit1.text) ;
end
else
ShowMessage('此'+Edit1.text+'方法,在project1.Dll中不存在');

印象笔记源码showmessage('加载project1.Dll异常');
印象笔记源码end;
印象笔记源码finally
印象笔记源码FreeLibrary(MyHandle) ;
印象笔记源码end;
