引言: 各位大大 假如有兩個應用程式A.EXE,B.EXE 是否可以把A.EXE中的資料(也許是某個structure) 像寄mail一樣，直接寄給B.EXE? 而不是透過某個 > < face="Verdana, Arial, Helvetica"> VickyTsai141 你好: 其實是可以做得到的，請參考以下的做法 < class="code"> // struct 的資料結構 typedef struct _MYSTRUCT { char szChar[16]; int iInt; } MyStruct; // Sender 端的程式碼, Unit1.cpp void __fastcall TForm1::Button1Click(TObject *Sender) { HWND hWnd=FindWindow(NULL, "ReceiveForm"); if(hWnd) { MyStruct ms; lstrcpy(ms.szChar, "This is my char"); ms.iInt=100; COPYDATASTRUCT CopyData; CopyData.dwData=0; CopyData.cbData=sizeof(MyStruct); CopyData.lpData=&ms; SendMessage(hWnd, WM_COPYDATA, (WPARAM)Handle, (LPARAM)&CopyData); } } // Receiver 端的程式碼, Unit1.h class TForm1 : public TForm { __published: // IDE-managed Components private: // User declarations void __fastcall WMCopyData(TMessage& Message); public: // User declarations __fastcall TForm1(TComponent* Owner); BEGIN_MESSAGE_MAP MESSAGE_HANDLER(WM_COPYDATA, TMessage, WMCopyData) END_MESSAGE_MAP(TForm) }; // Receiver 端的程式碼, Unit1.cpp void __fastcall TForm1::WMCopyData(TMessage& Message) { COPYDATASTRUCT *CopyData=(COPYDATASTRUCT*)(Message.LParam); if(CopyData->cbData==sizeof(MyStruct)) { MyStruct ms; CopyMemory(&ms, CopyData->lpData, CopyData->cbData); ShowMessage(ms.szChar); ShowMessage(IntToStr(ms.iInt)); } } -- Enjoy Researching & Developing --

兄,好用穩定方便通用的好方法.
