为什么创建的编辑控件没有水平滚动条

[AK47DCJ]

我的代码如下，按理应该没有水平滚动条

#include<windows.h>

#define ID_EDIT 1

HINSTANCE hIns;

LRESULT CALLBACK WindowProc(HWND hwnd, UINT uMsg,
WPARAM wParam, LPARAM lParam);

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,
LPSTR szCmdLine, int nCmdShow)
{
TCHAR szAppName[15] = TEXT("PopPad2");
HWND hwnd;
MSG msg;
WNDCLASS wndclass;

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 = WindowProc;
wndclass.lpszClassName = szAppName;
wndclass.lpszMenuName = NULL;
wndclass.style = CS_HREDRAW | CS_VREDRAW;

RegisterClass(&wndclass);

hwnd = CreateWindow(szAppName, szAppName,
WS_OVERLAPPEDWINDOW,
CW_USEDEFAULT, CW_USEDEFAULT,
CW_USEDEFAULT, CW_USEDEFAULT,
NULL, NULL, hInstance, NULL);
ShowWindow(hwnd, nCmdShow);
UpdateWindow(hwnd);
hIns = hInstance;
while(GetMessage(&msg, NULL, 0, 0))
{
TranslateMessage(&msg);
DispatchMessage(&msg);
}
return msg.wParam;
}

LRESULT CALLBACK WindowProc(HWND hwnd, UINT uMsg,
WPARAM wParam, LPARAM lParam)
{
static HMENU hMenu, hMenuPop;
static HWND hwndEdit;
static int cxClient, cyClient;
switch(uMsg)
{
case WM_CREATE:
hwndEdit = CreateWindow(TEXT("edit"), NULL,
WS_CHILDWINDOW | WS_VISIBLE | WS_HSCROLL | WS_VSCROLL |
WS_BORDER | ES_LEFT | ES_MULTILINE |
ES_AUTOHSCROLL | ES_AUTOVSCROLL,
0, 0, cxClient, cyClient,
hwnd, (HMENU)ID_EDIT,
hIns,
NULL);

return 0;
case WM_SIZE:
cxClient = LOWORD(lParam);
cyClient = LOWORD(lParam);
MoveWindow(hwndEdit, 0, 0, cxClient, cyClient, TRUE);
return 0;
case WM_DESTROY:
PostQuitMessage(0);
return 0;
}
return DefWindowProc(hwnd, uMsg, wParam, lParam);
}

你在里面输入字符，超过它一次性能显示的字符后就会出现滚动条啦

看不懂
lz的意思到底是应该有还是没有呢？

对不起，说错了，我加了
WS_VSCROLL 和WS_HSCROLL 按理应该有滚动条，
编译运行后只有垂直滚动条，没有水平滚动条！
希望高手指点一下，是那里出问题了， 多谢了！！！

设置　多行　属性　了吗？

[AK47DCJ]

用CreateWindow创建编辑框时加了ES_MULTILINE,应该算设置了多行属性，可是还是没有水平滚动条啊！
希望各位高手帮小弟看看是哪出问题了，是不是编译器的设置出了问题!
多谢！多谢！

WS_VSCROLL | WS_HSCROLL
指定了就会有的。
