总显示编译错误，未声明名称“_lVars”

Dim camList As WinForm.ComboBox = e.Form.Controls("CamList")
'设置控件大小
Functions.Execute("SetCamBoxSize",e.Form,True)
'设置移动条
e.Form.Controls("BarX").Value = e.Form.Controls("LineBox").Left - e.Form.Controls("CamViewBox").Left
e.Form.Controls("BarY").Value = e.Form.Controls("CamViewBox").Height - (e.Form.Controls("LineBox").Top - e.Form.Controls("CamViewBox").Top)
e.Form.Controls("BarW").Value = e.Form.Controls("LineBox").Width
e.Form.Controls("BarH").Value = e.Form.Controls("CamViewBox").Height - e.Form.Controls("LineBox").Height
'显示拍照框尺寸
e.Form.Controls("BoxW").Value = e.Form.Controls("LineBox").Width
e.Form.Controls("BoxH").Value = e.Form.Controls("LineBox").Height
_lVars(0) = e.Form.Controls("AutoTake").Checked
'设置保存路径
If _sVars(0) <> ""
    e.Form.Controls("FileName").Value = _sVars(0)
End If
'获取摄像头列表
Functions.Execute("GetCams")
'显示摄像头列表
Dim i As Integer
camList.Items.Clear
For i=0 To _CamList.Count - 1
    camList.Items.Add(_CamList(i))
Next
'默认选中第一个摄像头
If _CamList.Count > 1 And _CamIndex < 1
    _CamIndex = 1
End If
camList.SelectedIndex = _CamIndex
'激活预览
If _CamList.Count > 0
    Functions.Execute("SetCamView",_CamIndex,e.Form.Controls("CamView"))
Else
    MessageBox.Show("未检测摄像头,请先连接摄像头!","警告")
    e.Form.Close()
End If
'启动定时器
_iVars(0) = 0
e.Form.TimerEnabled = True

设置全局代码

老师您好，我在全局变量中设置：

'临时共享变量
Public _sVars(100) As String
Public _dVars(100) As Date
Public _bVars(100) As Boolean
Public _iVars(100) As Integer
Public _lVars(100) As Long

'摄像头
Public _Cap As DCap.Capture
Public _Cams As DCap.Filters = New DCap.Filters()
Public _Cam As DCap.Filter
Public _CamList As New List(Of String)
Public _CamIndex As Integer

总是出错：编译错误：未定义类型“DCap.Capture”

错误代码：pubic_Cap As DCap.Capture

红色的三行都会显示错误。

把dll文件引入，设置命名空间
