Hi all,
Can any one please help me how to call an function from dll in vc++.
// test1.cpp : Defines the entry point for the console application.
//
#include "stdafx.h"
#include "windows.h"
#include "conio.h"
#include "windef.h"
int _tmain(int argc, _TCHAR* argv[])
{
HINSTANCE instcall=LoadLibrary(TEXT("c:\\test2.dll"));
if(instcall==NULL)
printf("Failed to load dll");
FARPROC getproc=GetProcAddress(instcall,"funcall");
if(getproc==NULL)
printf("failed entry point");
typedef int(__stdcall * picFunc)();
picFunc funcall;
funcall=picFunc(getproc);
funcall();
getch();
//LPTSTR path=(LPTSTR)"c:\test2.dll";
/*system("notepad.exe");
DWORD threadId=dwThredId*/
/*typedef void *(_stdcall *creatfn)();
creatfn myfunc=(creatfn) GetProcAddress(instcall,"call");
void *objptr=myfunc();*/
/*picFunc funcall;*/
//=picFunc(getproc);
//funcall();
///call=mycall(getproc);
}
I have this code in the main file
the dll file code is below
// test2.cpp : Defines the exported functions for the DLL application.
//
#include "stdafx.h"
#include "stdio.h"
#include "conio.h"
void funcall()
{
printf("hello");
}
When i execute i get this exception Unhandled exception at 0x00000000 in test1.exe: 0xC0000005: Access violation reading location 0x00000000.
Can any one please help me out in solving this problem. I am using Visual studio 2008 as compiler
Thank you
