vb.net拓扑寻路的简单介绍

怎样用VB.NET进行网络编程?

都可以,可以用winsock,也可以自己重写SOCKET套接字.建议你如果工期紧,可以先用WINSOCK.当然最好是自己学用SOCKET套接字.这对未来开发网络通讯是很有帮助的.因为用WINSOCK有个毛病就是杀毒软件总会阻止

用vb.net实现网络通信

用 vb.net socket通信

Dim th As Threading.Thread

①.0 Try

①.1 If IP "" Then

用vb.netl编写的floyd算法求两点间的最短路径,怎么输出path经过的顶点序列?

Function Min(x() as integer,y() as integer) as double

dim i,j,k,a

dim m() as double

dim s() as string

dim mins as string

redim m(ubound(x),ubound(x))

redim s(ubound(x),ubound(x))

for i=1 to ubound(x)-1 '从起始点0点到i点的距离

s(i,0)="0-" cstr(i)

next

for i=1 to ubound(x)-1

for j=1 to ubound(x)-1

if instr(s(j,k-1),cstr(i))=0 then'避免重复走一点

if a+m(j,k-1)m(i,k) then

m(i,k)=a+m(j,k-1)

s(i,k)=s(j,k-1) "-" cstr(i)

endif

end if

'计算经过各点后到达最后一个点的最短距离

msgbox "最短距离:" min vbcrlf "最短路径:" mins

End function

private sub Command1_Click

dim m as double

x(0)=0

y(0)=0

......

m=min(x,y)

End sub
