I've been using dev c++ while learning c++ for the past two years. I want to learn to use the win32 api which works fine with devc++.
However, as I will eventually want to use directx, I downloaded visual studio 2008 express.
The code that works in devc++ does not work in vs.
I'm sure that its just a setup issue, but with the mass of info regarding vs 2008 I can't seem to figure out whats going on.
As I say, I'm new to windows programming and i'm finding he learning curve pretty steep.
This is the basic code i'm trying to compile:
#include <windows.h>
HINSTANCE hInst;
HWND wndHandle;
bool initWindow(HINSTANCE hInstance);
LRESULT CALLBACK WndProc(HWND, UINT, WPARAM, LPARAM);
int WINAPI WinMain(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPTSTR lpCmdLine, int nCmdShow)
{
if (!initWindow(hInstance))
return false;
// Main message loop:
MSG msg;
ZeroMemory( &msg, sizeof(msg) );
while( msg.message!=WM_QUIT )
{
if( PeekMessage( &msg, NULL, 0U, 0U, PM_REMOVE ) )
{
TranslateMessage( &msg );
DispatchMessage( &msg );
}
}
return (int) msg.wParam;
}
bool initWindow(HINSTANCE hInstance)
{
WNDCLASSEX wcex;
wcex.cbSize = sizeof(WNDCLASSEX);
wcex.style = CS_HREDRAW | CS_VREDRAW;
wcex.lpfnWndProc = (WNDPROC)WndProc;
wcex.cbClsExtra = 0;
wcex.cbWndExtra = 0;
wcex.hInstance = hInstance;
wcex.hIcon = 0;
wcex.hCursor = LoadCursor(NULL, IDC_ARROW);
wcex.hbrBackground = (HBRUSH)(COLOR_WINDOW+1);
wcex.lpszMenuName = NULL;
wcex.lpszClassName = "DirectXExample";
wcex.hIconSm = 0;
RegisterClassEx(&wcex);
wndHandle = CreateWindow("DirectXExample",
"DirectXExample",
WS_OVERLAPPEDWINDOW,
CW_USEDEFAULT,
CW_USEDEFAULT,
640,
480,
NULL,
NULL,
hInstance,
NULL);
if (!wndHandle)
return false;
ShowWindow(wndHandle, SW_SHOW);
UpdateWindow(wndHandle);
return true;
}
LRESULT CALLBACK WndProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam)
{
switch (message)
{
case WM_DESTROY:
PostQuitMessage(0);
break;
}
return DefWindowProc(hWnd, message, wParam, lParam);
}
and this is the error i'm getting:

If there is something simple that I'm missing, please enlighten me.
If not, is there a book or web resourse that will help.
Thanks
