vb6.0中如何自动篇历系统的全部驱动器并获得全部信息？

Answer 1

假如只是想列驱动器名，如下很简单的，网络驱动器映射后也一样能列出。
‘列出所有驱动器，不含A，B
Dim drv() As String
Dim sd As String
drv() = Split("C,D,E,F,G,H,I,J,K,L,M,N,O,P,Q,R,S,T,U,V,W,X,Y,Z", ",")
For i = 0 To 23
sd = drv(i) & ":\"
If Dir(sd, vbDirectory) <> "" Then
comb.AddItem sd ’添加到列表中
End If
Next
