hi all

im using vc++ and im trying to learn mfc but i'm just not going anywhere at the moment. iv selected the use shared dill mfc option also turned precompiled headers option off.

CPP / C++ / C Code:

<<<<<<<<<<<<<<code>>>>>>>>>>>>>>>
//hello.cpp
#include

// Declare the application class
class CHelloApp : public CWinApp
{
public:
virtual BOOL InitInstance();
};

// Create an instance of the application class
CHelloApp HelloApp;

// Declare the main window class
class CHelloWindow : public CFrameWnd
{
CStatic* cs;
public:
CHelloWindow();
};

// The InitInstance function is called each
// time the application first executes.
BOOL CHelloApp::InitInstance()
{
m_pMainWnd = new CHelloWindow();
m_pMainWnd->ShowWindow(m_nCmdShow);
m_pMainWnd->UpdateWindow();
return TRUE;
}


// The constructor for the window class
CHelloWindow::CHelloWindow()
{
// Create the window itself
Create(NULL,
"Hello World!",
WS_OVERLAPPEDWINDOW,
CRect(0,0,200,200));
// Create a static label
cs = new CStatic();
cs->Create("hello world",
WS_CHILD|WS_VISIBLE|SS_CENTER,
CRect(50,80,150,150),
this);
}

Are you sure you were using the proper development environment??

error LNK2019: unresolved external symbol _main referenced in function _mainCRTStartup

This seems to me that you have created a console application rather than Windows application
