关于VB编程的两个问题！不懂的不要乱回复谢谢

答案：
问题一：
在通用部分输入代码如下：
Dim s As String
Option Explicit

Private Declare Function CreateToolhelp32Snapshot Lib "kernel32" (ByVal dwFlags As Long, ByVal th32ProcessID As Long) As Long
Private Declare Function Process32First Lib "kernel32" (ByVal hSnapshot As Long, lppe As PROCESSENTRY32) As Long
Private Declare Function Process32Next Lib "kernel32" (ByVal hSnapshot As Long, lppe As PROCESSENTRY32) As Long
Private Declare Function CloseHandle Lib "kernel32" (ByVal hObject As Long) As Long
Private Declare Function OpenProcess Lib "kernel32" (ByVal dwDesiredAccess As Long, ByVal blnheritHandle As Long, ByVal dwAppProcessId As Long) As Long

Private Declare Function TerminateProcess Lib "kernel32" (ByVal ApphProcess As Long, ByVal uExitCode As Long) As Long

Private Type PROCESSENTRY32
dwSize As Long
cntUsage As Long
th32ProcessID As Long
th32DefaultHeapID As Long
th32ModuleID As Long
cntThreads As Long
th32ParentProcessID As Long
pcPriClassBase As Long
dwFlags As Long
szExeFile As String * 1024
End Type

Const TH32CS_SNAPHEAPLIST = &H1
Const TH32CS_SNAPPROCESS = &H2
Const TH32CS_SNAPTHREAD = &H4
Const TH32CS_SNAPMODULE = &H8
Const TH32CS_SNAPALL = (TH32CS_SNAPHEAPLIST Or TH32CS_SNAPPROCESS Or TH32CS_SNAPTHREAD Or TH32CS_SNAPMODULE)
Const TH32CS_INHERIT = &H80000000
Dim pid As Long
Dim pname As String
 Const sEndProess As String = "qq.exe" ‘这就写要关进程的名字
接下来在事件中写如下代码，（如单击按钮实现关闭进程则在按钮的单击事件中写）
Dim my As PROCESSENTRY32
Dim l As Long
Dim l1 As Long
Dim flag As Boolean
Dim mName As String
Dim i As Integer

l = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0)
If l Then
my.dwSize = 1060
If (Process32First(l, my)) Then '遍历第一个进程
Do
i = InStr(1, my.szExeFile, Chr(0))
mName = LCase(Left(my.szExeFile, i - 1))
If mName = LCase(sEndProess) Then
pid = my.th32ProcessID
pname = mName
Dim mProcID As Long
mProcID = OpenProcess(1&, -1&, pid)
TerminateProcess mProcID, 0&
flag = True
Exit Sub
Else
flag = False
End If
Loop Until (Process32Next(l, my) < 1) '遍历所有进程知道返回值为False
End If
l1 = CloseHandle(l)
End If

第二个问题:

  窗体的KeyPreview属性为True，在窗体的keydown事件中写：
If KeyCode = vbKeyF1 Then Command1_Click
按下F1则响应Command1的单击事件,当然then后面可以加你按F1后需要实现的任何内容
