用 C++ Builder 寫DLL及測試DLL代碼 (留記錄)

一、DLL入口聲明

extern"C"__declspec(dllexport)int__stdcall fnDoFaceRecOut(charfileFaceIni);



int__stdcall fnDoFaceRecOut(charfileFaceIni)

{

AnsiString filename=fileFaceIni;

//....return0;

}

二、測試 DLL代碼

void__fastcall TForm1::BitBtn2Click(TObjectSender)

{

HINSTANCE dd;

typedefint_stdcall (deffnDoFaceRecGenMap)(char*fileFaceIni);

deffnDoFaceRecGenMap fnDoFaceRecGenMap;

AnsiString CurrentDir=ExtractFilePath(ParamStr(0))+"FaceRecDll.dll";

dd=::LoadLibrary(CurrentDir.c_str());

AnsiString fileFaceIni="";

if(dd)

{

if(OpenDialog1->Execute())

{

fnDoFaceRecGenMap=(deffnDoFaceRecGenMap) GetProcAddress(dd,"fnDoFaceRecGenMap");

if(fnDoFaceRecGenMap)

{

lblMessage->Caption="正在處理...";

Application->ProcessMessages();



Caption=IntToStr(fnDoFaceRecGenMap(OpenDialog1->FileName.c_str()));

lblMessage->Caption="處理完畢!";

}

}

}

}
