Events on WinApi C++

[skoumas]

Hello there.

I am using Visual C++ Express right now.

I dont want to make applications throught the automated processes that this pack offers me, cause application gets much larger than they should have bin.

Yesterday I made my first step on WinApi: this is the result.

#include <windows.h>


char* App_Title = "Skoumas and the brains at the kangela";


LRESULT WINAPI myProc(HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam) 

{

	if(message == WM_CLOSE) {
	
		int apantisi;
		apantisi = MessageBox(NULL, "Are you Sure?",App_Title,1);

		if (apantisi==1)  
		PostQuitMessage(0);

		
	}
	return 0;
}

LRESULT WINAPI myProcbutton(HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam) 

{

	if(message == 1) {
	
		int apantisi;
		apantisi = MessageBox(NULL, "Are you Sure?",App_Title,1);

		if (apantisi==1)  
		PostQuitMessage(0);

		
	}
	return 0;
}


int APIENTRY WinMain(HINSTANCE, HINSTANCE, LPSTR, int)

{
MSG msg;


	HWND myDialog=CreateWindowEx(0, WC_DIALOG, App_Title, WS_OVERLAPPEDWINDOW | WS_VISIBLE,
		600, 100, 400, 200, NULL, NULL,NULL,NULL 
	);

	HWND button1=CreateWindowEx(	0,"BUTTON",	"My Button",BS_PUSHBUTTON | WS_VISIBLE | WS_CHILD,
		50,50,100,25,myDialog,NULL,NULL,NULL

	);

	
SetWindowLong(myDialog,	DWL_DLGPROC, (long) myProc);
SetWindowLong(button1,	DWL_DLGPROC, (long) myProcbutton);


	while(GetMessage(&msg,NULL,0,0)) 
	{
		TranslateMessage(&msg);
		DispatchMessage(&msg); 

	} 


	return 0;

}

In this code you can see that the program generates a simple window and a button inside it.

I want to be able when i press the button to show a message box.

Can you please help me?
