체크박스
생성방법은 이전의 푸쉬버튼과 동일하다.
CreateWindow(TEXT( "button"),TEXT("Draw Ellipse?" ),WS_CHILD | WS_VISIBLE | BS_CHECKBOX,20,20,160,25,hWnd,(HMENU)0,g_hInst,NULL);
체크박스는 주로 참과 거짓을 선택할때 사용한다.
우선 기본적인 체크박스는 선택/비선택의 상태를 가지고 3가지 상태를 가지는 체크박스는 두경우를 제외하고도 Grayed라는 제3의 상태를 가진다.
또한 수동과 자동(윈도우즈가 자동 설정)으로 선택하는 체크박스로 나뉘어 총 4가지의 종류가 이루어져있다.

스크롤 바
스크롤 바는 지금까지의 컨트롤에 비해서는 비교적 복잡한 컨트롤이다.
수치로 된 정확한 값보다는 정확하지 않은 값을 신속하게 요구할 경우 사용한다.
BOOL SetScrollRange( HWND hWnd, int nBar, int nMinPos, int nMaxPos, BOOL bRedraw );
SetScrollRange 함수로 최대값(nMaxPos), 최소값(nMinPos)을 지정하되 첫번째 인수가 스크롤 바의 윈도우 핸들이다. 두번째 인수 nBar는 메인 윈도우에 부착된 스크롤 바 또는 별도의 스크롤 바 컨트롤을 지정하는데 이 값이 SBS_CTL이면 별도의 컨트롤을 지정한다.
SetScrollPos는 스크롤 바의 현재 위치를 세번째 인수 nPos로 지정한다.
또한 다른 컨트롤과는 달리 스크롤 바는 WM_HSCROLL(수평일 경우), WM_VSCROLL(수직일 경우)이라는 별도의 메시지를 부모 윈도우로 보낸 후 상태 변화 메시지를 보낸다.
LOWORD(wParam)으로 전달되는 값은 사용자의 스크롤 요구사항을 나타내며 가능한 값의 종류는 다음과 같다.

스태틱
스태틱은 모든 컨트롤을 통틀어 제일 간단한 컨트롤이다. 이유는 문자열을 출력하기만하는 것이 기능의 전부이기 때문이다.
주로 다른 컨트롤을 설명하는 역할을 한다.
스태틱을 사용하는 주된 이유는 TEXTOUT와는 다르게 스스로 메시지를 처리 할 수있으므로 지워질 염려가 없다.
다음은 스태틱의 스타일이다.

대화 상자
대화상자는 크게 모달형과 모델리스형으로 나뉘어진다. 모달(Modal)형은 대화상자를 닫기 전에 다른 윈도우로 전환할 수 없으며 반드시 OK버튼이나 Cancel 버튼을 눌러 대화상자를 닫아야 다른 윈도우로 전환할 수 있다.

모델리스형 대화상자
대화상자 생성방법
1. Dialog 리소스를 추가한후 편집한다.
2. 대화상자 프로시저를 작성(단 함수원형을 선언하지 않은경우 WinMain과 WndProc 사이에 선언)
BOOL CALLBACK AboutDlgProc(HWND hDlg,UINT iMessage,WPARAM wParam,LPARAM lParam)
{
switch (iMessage) {
case WM_INITDIALOG:
return TRUE;
case WM_COMMAND:
switch (LOWORD(wParam)) {
case IDOK:
EndDialog(hDlg,IDOK);
return TRUE;
case IDCANCEL:
EndDialog(hDlg,IDCANCEL);
return TRUE;
}
break;
}
return FALSE;
}
3. 마지막으로 WndProc에서 필요할 때에 대화상자를 호출
LRESULT CALLBACK WndProc(HWND hWnd,UINT iMessage,WPARAM wParam,LPARAM lParam)
{
switch (iMessage) {
case WM_LBUTTONDOWN:
DialogBox(g_hInst,MAKEINTRESOURCE(IDD_DIALOG1),hWnd,AboutDlgProc);
return 0;
case WM_DESTROY:
PostQuitMessage(0);
return 0;
}
return(DefWindowProc(hWnd,iMessage,wParam,lParam));
}
<소스코드 예제 : About>
#include <windows.h>
LRESULT CALLBACK WndProc(HWND,UINT,WPARAM,LPARAM);
HINSTANCE g_hInst;
LPCTSTR lpszClass=TEXT( "First");
int APIENTRY WinMain(HINSTANCE hInstance,HINSTANCE hPrevInstance
,LPSTR lpszCmdParam, int nCmdShow)
{
HWND hWnd;
MSG Message;
WNDCLASS WndClass;
g_hInst=hInstance;
WndClass.cbClsExtra=0;
WndClass.cbWndExtra=0;
WndClass.hbrBackground=(HBRUSH)GetStockObject(WHITE_BRUSH);
WndClass.hCursor=LoadCursor(NULL,IDC_ARROW);
WndClass.hIcon=LoadIcon(NULL,IDI_APPLICATION);
WndClass.hInstance=hInstance;
WndClass.lpfnWndProc=WndProc;
WndClass.lpszClassName=lpszClass;
WndClass.lpszMenuName=NULL;
WndClass.style=CS_HREDRAW | CS_VREDRAW;
RegisterClass(&WndClass);
hWnd=CreateWindow(lpszClass,lpszClass,WS_OVERLAPPEDWINDOW,
CW_USEDEFAULT,CW_USEDEFAULT,CW_USEDEFAULT,CW_USEDEFAULT,
NULL,(HMENU)NULL,hInstance,NULL);
ShowWindow(hWnd,nCmdShow);
while (GetMessage(&Message,NULL,0,0)) {
TranslateMessage(&Message);
DispatchMessage(&Message);
}
return (int )Message.wParam;
}
#include "resource.h"
BOOL CALLBACK AboutDlgProc(HWND hDlg,UINT iMessage,WPARAM wParam,LPARAM lParam)
{
switch (iMessage) {
case WM_INITDIALOG:
return TRUE;
case WM_COMMAND:
switch (LOWORD(wParam)) {
case IDOK:
EndDialog(hDlg,IDOK);
return TRUE;
case IDCANCEL:
EndDialog(hDlg,IDCANCEL);
return TRUE;
}
break;
}
return FALSE;
}
LRESULT CALLBACK WndProc(HWND hWnd,UINT iMessage,WPARAM wParam,LPARAM lParam)
{
switch (iMessage) {
case WM_LBUTTONDOWN:
DialogBox(g_hInst,MAKEINTRESOURCE(IDD_DIALOG1),hWnd,AboutDlgProc);
return 0;
case WM_DESTROY:
PostQuitMessage(0);
return 0;
}
return(DefWindowProc(hWnd,iMessage,wParam,lParam));
}

대화상자를 이용하여 계산기를 구현해 보도록 한다.
