您可以使用以下代码在VB6.0中模拟按下Ctrl键未放,再按下C键:
```
Public Declare Sub keybd_event Lib "user32" (ByVal bVk As Byte, ByVal bScan As Byte, ByVal dwFlags As Long, ByVal dwExtraInfo As Long)
Const VK_CONTROL = &H11
Const VK_C = &H43
keybd_event VK_CONTROL, 0, 0, 0 '按下Ctrl键
keybd_event VK_C, 0, 0, 0 '按下C键
```
这段代码和上一个例子相比,少了释放Ctrl键和C键的代码。这样就可以模拟按下Ctrl键未放,再按下C键的操作。如果您需要释放这些键,可以在适当的时候添加释放键的代码。

用VB6.0模拟键盘同时按下ctrl和C
您可以使用以下代码在VB6.0中模拟同时按下Ctrl和C键:
```
Public Declare Sub keybd_event Lib "user32" (ByVal bVk As Byte, ByVal bScan As Byte, ByVal dwFlags As Long, ByVal dwExtraInfo As Long)
Const VK_CONTROL = &H11
Const VK_C = &H43
keybd_event VK_CONTROL, 0, 0, 0 '按下Ctrl键
keybd_event VK_C, 0, 0, 0 '按下C键
keybd_event VK_C, 0, KEYEVENTF_KEYUP, 0 '释放C键
keybd_event VK_CONTROL, 0, KEYEVENTF_KEYUP, 0 '释放Ctrl键
```
这段代码和上一个例子基本相同,不同之处在于在第三行和第四行同时按下了Ctrl和C键。
用VB6.0模拟键盘按下ctrl+C
您可以使用以下代码在VB6.0中模拟按下Ctrl+C:
```
Public Declare Sub keybd_event Lib "user32" (ByVal bVk As Byte, ByVal bScan As Byte, ByVal dwFlags As Long, ByVal dwExtraInfo As Long)
Const VK_CONTROL = &H11
Const KEYEVENTF_KEYUP = &H2
keybd_event VK_CONTROL, 0, 0, 0 '按下Ctrl键
keybd_event &H43, 0, 0, 0 '按下C键
keybd_event &H43, 0, KEYEVENTF_KEYUP, 0 '释放C键
keybd_event VK_CONTROL, 0, KEYEVENTF_KEYUP, 0 '释放Ctrl键
```
这段代码使用了Windows API函数`keybd_event`来模拟键盘按下。首先按下Ctrl键,然后按下C键,接着释放C键和Ctrl键。
