无法从C DLL调用函数

//DLL Code

#include <stdio.h>

extern "C"

{


__declspec(dllexport) void DisplayHelloFromDLL()

    {
        printf("Hello from DLL !\n");
    }
}


//Program Accessing DLL

#include<windows.h>
#include<iostream>
#include<conio.h>

typedef void (*DisplayHelloFromDLLFuncPtr)();
using namespace std;



int main()

{

    HINSTANCE hGetProcIDDLL = LoadLibrary("L:\\C_Learning\\Library\\MyLib\\Debug\\MyLib.dll");
    if (!hGetProcIDDLL)
    {

        cout << "\nCould Not The Library";
        return EXIT_FAILURE;

    }

    else

    {
        cout << "\nDLL is Loaded";

    }

    DisplayHelloFromDLLFuncPtr LibMainEntryPoint=(DisplayHelloFromDLLFuncPtr)GetProcAddress(hGetProcIDDLL, "DisplayHelloFromDLL");

    if (!DisplayHelloFromDLL)
    {

        cout << "\nCould not locate the function";
        return EXIT_FAILURE;
    }

    cout << DisplayHelloFromDLL(); 

    return EXIT_SUCCESS;

    _getch();
    return 0;


}

1. 代码在else条件下执行直到cout语句。

3. 收到错误“DisplayHelloFromDLL”:未声明的标识符

4. 视情况而定。exe,确认DLL地址空间中的函数可用性。

5. DLL和示例程序在32位环境下编译。

   有什么建议吗?
