推荐答案

尝试一下:

声明功能capGetDriverDescriptionA库"avicap32.dll"(ByVal wDriver为简称，_
ByVal lpszName作为字符串，ByVal cbName作为整数，ByVal lpszVer作为字符串，_
ByVal cbVer As Integer)As Boolean



用法:

Dim strName As String =空格(100)
Dim strVer As String =空格(100)
Dim bReturn为布尔值
Dim x As Integer = 0

''
bReturn = capGetDriverDescriptionA(x，strName，100，strVer，100)

msgbox(设备名称="&strName)

Try this :

Declare Function capGetDriverDescriptionA Lib "avicap32.dll" (ByVal wDriver As Short, _
ByVal lpszName As String, ByVal cbName As Integer, ByVal lpszVer As String, _
ByVal cbVer As Integer) As Boolean



Usage :

Dim strName As String = Space (100)
Dim strVer As String = Space (100)
Dim bReturn As Boolean
Dim x As Integer = 0

''
bReturn = capGetDriverDescriptionA (x, strName, 100, strVer, 100)

msgbox("Device name ="& strName)
