VB多进程怎么做啊？就是那个啥activex exe的，能详细一点吗？

VB的多线程比较吃力。多个线程最后想出的办法是用多个进程也就是你说的exe代替多个线程。一个form就是一个进程你搞几个from其实就是多进程也就是类似的多线程但是比较麻烦点而已，顺便给个建议VB.NET可以轻松解决多线程。

Vb 多进程技术

调用 2.exe 用 shell 方法就可以了.不用多说.

至于检测 5个 2.exe 是否全都结束的方法,可以在 1.exe 中添加1个TIMER ,设定每隔1秒遍历系统进程表.]

找出系统进程中 2.exe 的个数,若为 0个 则显示"处理完成"

遍历进程需要调用API：

Declare Function CreateToolhelpSnapshot Lib "kernel32" Alias "CreateToolhelp32Snapshot" (ByVal lFlags As Long, ByVal lProcessID As Long) As Long

Declare Function ProcessFirst Lib "kernel32" Alias "Process32First" (ByVal hSnapShot As Long, uProcess As PROCESSENTRY32) As Long

Declare Function ProcessNext Lib "kernel32" Alias "Process32Next" (ByVal hSnapShot As Long, uProcess As PROCESSENTRY32) As Long

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

Declare Function OpenProcess Lib "kernel32" (ByVal dwDesiredAccess As Long, ByVal bInheritHandle As Long, ByVal dwProcessId As Long) As Long

Declare Function CloseHandle Lib "kernel32" (ByVal hObject As Long) As Long

Public Declare Function ShellExecute Lib "shell32.dll" Alias "ShellExecuteA" (ByVal hwnd As Long, ByVal lpOperation As String, ByVal lpFile As String, ByVal lpParameters As String, ByVal lpDirectory As String, ByVal nShowCmd As Long) As Long

Const MAX_PATH As Integer = 260

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 * MAX_PATH

End Type

Const TH32CS_SNAPheaplist = H1

Const TH32CS_SNAPPROCESS = H2

Const TH32CS_SNAPthread = H4

Const TH32CS_SNAPmodule = H8

Public Const TH32CS_SNAPall = TH32CS_SNAPPROCESS + TH32CS_SNAPheaplist + TH32CS_SNAPthread + TH32CS_SNAPmodule

'下面的"GetCount" 函数用于返回 2.exe 的个数:

Public Function GetCount()

Dim i As Long, lPid As Long

Dim k As Long

Dim Proc As PROCESSENTRY32

Dim hSnapShot As Long

hSnapShot = CreateToolhelpSnapshot(TH32CS_SNAPall, 0) '获得进程“快照”的句柄

Proc.dwSize = Len(Proc)

lPid = ProcessFirst(hSnapShot, Proc) '获取第一个进程的PROCESSENTRY32结构信息数据

i = 0

k = 0

Do While lPid 0

If InStr(1, Proc.szExeFile, "2.exe", vbTextCompare) 0 Then

k = k + 1

End If

i = i + 1

lPid = ProcessNext(hSnapShot, Proc) '循环获取下一个进程的PROCESSENTRY32结构信息数据

Loop

CloseHandle hSnapShot '关闭进程“快照”句柄

IsDone = k

End Function

VB.net 如何设计多线程运行

Sub Main()

Dim thr As Thread

For Pi As Integer=0 To 4 //启用5线程

MulParams =Pi vbTab sFile vbTab dFile vbTab 1 vbTab DelN vbTab cr vbTab cg vbTab cb vbTab IndexI

GlobalParamas(pi)=MulParams .Split(vbTab)

thr=New Thread(AddressOf MyMulThreadCaller)

thr.Start() //启动多线程进程

Application.DoEvents

Next

End Sub
