BCB創建dll和VS使用dll方法 [VSCallBCBDll]
GITHUB: https://github.com/jash-git/VSCallBCBDll
01.BCB_DLL [建立測試用DLL]
CPP
//---------------------------------------------------------------------------
#include
#include
#pragma hdrstop
//---------------------------------------------------------------------------
// Important note about DLL memory management when your DLL uses the
// static version of the RunTime Library:
//
// If your DLL exports any functions that pass String objects (or structs/
// classes containing nested Strings) as parameter or function results,
// you will need to add the library MEMMGR.LIB to both the DLL project and
// any other projects that use the DLL. You will also need to use MEMMGR.LIB
// if any other projects which use the DLL will be performing new or delete
// operations on any non-TObject-derived classes which are exported from the
// DLL. Adding MEMMGR.LIB to your project will change the DLL and its calling
// EXE's to use the BORLNDMM.DLL as their memory manager. In these cases,
// the file BORLNDMM.DLL should be deployed along with your DLL.
//
// To avoid using BORLNDMM.DLL, pass string information using "char *" or
// ShortString parameters.
//
// If your DLL uses the dynamic version of the RTL, you do not need to
// explicitly add MEMMGR.LIB as this will be done implicitly for you
//---------------------------------------------------------------------------
#pragma argsused
extern "C" __declspec(dllexport) int BCBType_Count(int m, int n);
BOOL WINAPI DllMain(HINSTANCE hinstDLL, DWORD fwdreason, LPVOID lpvReserved)
{
return 1;
}
int BCBType_Count(int m, int n)
{
long sum = 0;
for(m; m<=n; m++)
{
sum += m;
}
return sum;
}
//---------------------------------------------------------------------------
產生DEF的BAT
impdef.exe BCB_DLL.def BCB_DLL.dll
BCB_DLL_Old.def[原始產生]
LIBRARY BCB_DLL.DLL
EXPORTS
_BCBType_Count @1 ; _BCBType_Count
___CPPdebugHook @2 ; ___CPPdebugHook
BCB_DLL.def[手動修改]
LIBRARY BCB_DLL.DLL
EXPORTS
BCBType_Count @1 ; _BCBType_Count
___CPPdebugHook @2 ; ___CPPdebugHook
02.CreateVCLIB [建立VC使用的LIB]
建立VC專用LIB的BAT
LIB /DEF:BCB_DLL.def
pause
03.VCCallBCBDll [VC使用LIB呼叫BCB DLL]
CPP
// VCCallBCBDll.cpp : 定義主控台應用程式的進入點。
//
#include "stdafx.h"
#include
using namespace std;
extern "C" __declspec(dllexport) int BCBType_Count(int m, int n);
void Pause()
{
printf("Press Enter key to continue...");
fgetc(stdin);
}
int main()
{
cout << "Hello world!" << endl;
cout << "1+2+3....+100=" << BCBType_Count(0, 100) << endl;
Pause();
return 0;
}
04.CSCallBCBDll [C#呼叫BCB DLL]
CS
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Runtime.InteropServices;//USE DLL
namespace CSCallBCBDll
{
class Program
{
[DllImport("./BCB_DLL.dll", CallingConvention = CallingConvention.Cdecl, CharSet = CharSet.Ansi, EntryPoint = "_BCBType_Count")]
public static extern int BCBType_Count(int m, int n);
static void Pause()
{
Console.Write("Press any key to continue...");
Console.ReadKey(true);
}
static void Main(string[] args)
{
Console.WriteLine("1+2+3+...100={0}", BCBType_Count(0, 100));
Pause();
}
}
}
05.CBCallBCBDll [純C++ 利用WINDOWS API『LoadLibrary』直接使用CB DLL函數]
#include
#include
using namespace std;
//---
//不使用LIB動態載入DLL函數
//http://www.infernodevelopment.com/simple-c-dll-loading-message-box
#include
typedef int (*FuncPtr)(int m,int n);
//---不使用LIB動態載入DLL函數
void Pause()
{
printf("Press Enter key to continue...");
fgetc(stdin);
}
int main()
{
FuncPtr myDllFunc;
BOOL linkSuccessFlag = FALSE, fFreeResult;
HINSTANCE hinstLib = LoadLibrary("BCB_DLL.dll");
if (hinstLib != NULL)
{
myDllFunc = (FuncPtr) GetProcAddress(hinstLib, "_BCBType_Count");
if (myDllFunc != NULL)
{
cout << "1+2+3+...+100=" << myDllFunc(1,100) <
