问一个简单的问题--怎么用keybd_event()模拟回车键?

[kaiki]

keybd_event(bVk,bScan,dwFlags,dwExtraInfo)中的各参数分别应为什么?
谢谢!

[sonicdater]

现在手上没资料.
只记得 要用 的其中一个参数 是 VKF1("F1"键) 之类的 常数, 还有一个是
键盘上的键 对于 系统底层的 常数, 要先用 另外一个 api 获得. 你 查查 msdn .

Declare Sub keybd_event Lib "user32.dll" (ByVal bVk As Byte, ByVal bScan As Byte, ByVal dwFlags As Long, ByVal dwExtraInfo As Long)

?bVk
Specifies a virtual-key code. The code must be a value in the range 1 to 254.

?bScan
Specifies a hardware scan code for the key.

fdwFlags
A set of flag bits that specify various aspects of function operation. An application can use any combination of the following predefined constant values to set the flags:
KEYEVENTF_EXTENDEDKEY
If specified, the scan code was preceded by a prefix byte having the value 0xE0 (224).
KEYEVENTF_KEYUP
If specified, the key is being released. If not specified, the key is being depressed.

?dwExtraInfo
Specifies an additional 32-bit value associated with the key stroke.

Const VK_H = 72
Const VK_E = 69
Const VK_L = 76
Const VK_O = 79
Const KEYEVENTF_EXTENDEDKEY = &H1
Const KEYEVENTF_KEYUP = &H2
Private Declare Sub keybd_event Lib "user32.dll" (ByVal bVk As Byte, ByVal bScan As Byte, ByVal dwFlags As Long, ByVal dwExtraInfo As Long)
Private Sub Form_KeyPress(KeyAscii As Integer)
'Print the key on the form
Me.Print Chr$(KeyAscii);
End Sub
Private Sub Form_Paint()

keybd_event VK_E, 0, 0, 0 ' press E
keybd_event VK_E, 0, KEYEVENTF_KEYUP, 0 ' release E
keybd_event VK_L, 0, 0, 0 ' press L
keybd_event VK_L, 0, KEYEVENTF_KEYUP, 0 ' release L
keybd_event VK_L, 0, 0, 0 ' press L
keybd_event VK_L, 0, KEYEVENTF_KEYUP, 0 ' release L
keybd_event VK_O, 0, 0, 0 ' press O
keybd_event VK_O, 0, KEYEVENTF_KEYUP, 0 ' release O
End Sub

用sendkeys行不行？

sendkeys"{Enter}"就搞定啦。

[kaiki]

不能用sendkeys函数，只能用api函数实现
keybd＿event中
"a"的bVk＝65;"b"的bVk＝66;"c"的bVk＝67.......
这些我都知道了，但是我现在想知道回车键的bVk参数是多少？？？
谢了！

[sonicdater]

Const VK_RETURN = &HD

[uguess]

YES!

[kaiki]

谢谢“发呆呆”
还想问一下，Alt键的bVk参数是多少？

[sonicdater]

Const VK_MENU = &H12

Alt ==> VK_Menu

[hydnoahark]

ALT key =VK_MENU(&H12)

另外,该谢,但也该"给分"呀!

[uguess]

我倒!! 又晚拉,兄弟们手都够快的!

[kaiki]

多谢大家！
分不够再加。
借此机会，我还想问一个问题
怎样向一个应用程序的文本框输入一段已确定的字符串？（用vb程序自动完成）

[uguess]

老哥，你的分还在路上么？

[kaiki]

不好意思，上次给分的时候给不了。

[81083]

ok.

[ddjsh]

不错,回答的真好.
