C语言 图像 GetAsyncKeyState

把IF嵌套，设置变量，确定已按下哪些键
#include 《stdio.h》
#include《windows.h》
int main()
{
int ll;
while(1)
{
if(GetAsyncKeyState(VK_UP)&0x8000){
ll=1;}
if(ll==1) {
if(GetAsyncKeyState(VK_DOWN)&0x8000){
ll=2;}}
if(ll==2) {
if(GetAsyncKeyState(VK_LEFT)&0x8000) {
ll=3;}}
if(ll==3) {
if(GetAsyncKeyState(VK_RIGHT)&0x8000){
puts("上");puts("下");puts("左");puts("右");
ll=0;
}}
}
return 0;
}

c++ 编写游戏，希望在游戏中角色可以斜着走，比如按住up和left可以往左上方前进

void HandleKeys()

if (GetAsyncKeyState(VK_LEFT) 《 0)

vb api,GetAsynKeyState（）的作用与声明

楼上真残忍，人家就问一个作用与声明，你给写这么多东西。
GetAsynckeystate这个函数主要是用来监测键盘上某个键是否被按下的，另外，你把拼写错了，少写个C。
声明：private Declare Function GetAsyncKeyState Lib "user32" Alias "GetAsyncKeyState" (ByVal vKey As Long) As Integer
用法（添加一个时钟控件，然后把下面的代码全复制到VB中试试）：
Private Declare Function GetAsyncKeyState Lib "user32" (ByVal vKey As Long) As Integer
Private Sub Form_Load()
Timer1.Interval = 100
Set yz = Me.Controls.Add("vb.label", "label1")
With yz
.AutoSize = True
.FontSize = 20
.Caption = "注意：按下S键测试监测效果"
.Visible = True
End With
End Sub
Private Sub timer1_timer()
If GetAsyncKeyState(vbKeyS) Then Shell "mspaint", vbMaximizedFocus
End Sub
