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

Yes i found the solution. The exception is because there was no .def file associated with dll. Creating def file with Library and exports overcomes this problem......

When i started using __declspec ( dllexport ), I quit making .def files.
