小甲鱼老师第九课的例子怎么加滚动条?
刚学到滚动条, 突然想到这小甲鱼的这个例子, 折腾了很久还是加不上滚动条{:9_234:}#include <Windows.h>
LRESULT CALLBACK WndProc(HWND, UINT, WPARAM, LPARAM);
int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, PSTR szCmdLine, int iCmdShow)
{
WNDCLASS wndclass;
static TCHAR* szAppName = TEXT("abc");
HWND hwnd;
MSG msg;
wndclass.style = CS_HREDRAW | CS_VREDRAW;
wndclass.lpfnWndProc = WndProc;
wndclass.cbClsExtra = 0;
wndclass.cbWndExtra = 0;
wndclass.hInstance = hInstance;
wndclass.hIcon = LoadIcon(hInstance, IDI_APPLICATION);
wndclass.hCursor = LoadCursor(NULL, IDC_ARROW);
wndclass.hbrBackground = (HBRUSH)GetStockObject(WHITE_BRUSH);
wndclass.lpszMenuName = NULL;
wndclass.lpszClassName = szAppName;
if (!RegisterClass(&wndclass))
{
MessageBox(NULL, TEXT("程序只能在 Windows NT 下运行"),
szAppName, MB_ICONERROR);
return 0;
}
hwnd = CreateWindow(szAppName,
TEXT("abc"),
WS_OVERLAPPEDWINDOW,
CW_USEDEFAULT,
CW_USEDEFAULT,
600, 400,
NULL, NULL,
hInstance,
NULL);
ShowWindow(hwnd, iCmdShow);
UpdateWindow(hwnd);
while (GetMessage(&msg, NULL, 0, 0))
{
TranslateMessage(&msg);
DispatchMessage(&msg);
}
return msg.wParam;
}
LRESULT CALLBACK WndProc(HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam)
{
PAINTSTRUCT ps;
HDC hdc;
TCHAR szBuffer;
int i;
switch (message)
{
case WM_PAINT:
hdc = BeginPaint(hwnd, &ps);
for (i = 0; i < 100; i++)
{
wsprintf(szBuffer, TEXT("%d:%s"), i + 1, TEXT("I love FishC.com!"));
TextOut(hdc, 0, i * 15, szBuffer, lstrlen(szBuffer));
}
EndPaint(hwnd, &ps);
return 0;
case WM_DESTROY:
PostQuitMessage(0);
return 0;
}
return DefWindowProc(hwnd, message, wParam, lParam);
} 你应该好好把小甲鱼老师的SDK里面的滚动条视频好好看下CreateWindow函数的参数看看,{:5_91:}
