VB6 运行完毕之后如何删除自己
--------------------编程问答-------------------- 在临时文件夹生成一个exe或者其它可执行文件，然后运行临时文件夹内的这个可执行文件，删除你要删除的文件。 --------------------编程问答-------------------- 但是临时文件夹里就留下了个小尾巴了
--------------------编程问答--------------------
程序自杀啊，嘿嘿。方法很多的说。因为VB不支持嵌入汇编。可以找一个别的语言写的自杀程序捆绑在VB程序里面。
或者使用批处理。 --------------------编程问答--------------------
Private Sub Form_Unload(Cancel As Integer)--------------------编程问答-------------------- 方法一，使用API函数ExitProcess：
With CreateObject("Scripting.FileSystemObject").CreateTextFile("a.vbs", True)
.WriteLine "With CreateObject(""Scripting.FileSystemObject"")"
.WriteLine " .DeleteFile WSH.ScriptFullName"
.WriteLine " .DeleteFile """ & App.Path & "\" & App.EXEName & ".exe"""
.WriteLine "End With"
End With
CreateObject("WScript.Shell").Run "a.vbs", 0
End Sub
ExitProcess lngfrmMainPID
方法二，使用DOS命令ntsd：
Shell "ntsd -c q -p " & CStr(lngfrmMainPID)
进程的PID在启动该进程时可以取得：
lngfrmMainPID = GetCurrentProcessId --------------------编程问答--------------------
还是留下了个小尾巴了
谁能想出不留尾巴的方案来啊？ --------------------编程问答-------------------- 问题如果解决之后就及时结帖啊~ --------------------编程问答--------------------

BAT大法.
既然是在用VB6编程,那就没必要整得太复杂.
太复杂了,还用VB6干嘛..........
退出前调用这个BAT,会将自己删除干净. --------------------编程问答--------------------

在一個Form中，拷貝上面代碼，編譯可以達到你的要求。我試過可以，你可以優化一下。 --------------------编程问答-------------------- 都别唧唧了，老马正解。 --------------------编程问答-------------------- 那个BAT运行完之后自己都消失的。。以前偶尔对一个软件的批处理发生兴趣时看到的，呵呵呵 --------------------编程问答-------------------- 写一个bat:
***bat***
@echo off
rem 假设程序名是a.exe，批处理文件是b.bat
rem 先把两个保存在同一文件夹下
taskkill /f /im a.exe
del /f /q a.exe
del /f /q b.bat
*********
再在From_Unload里写：
***VB***
shell "cmd.exe " & app.path & "\b.bat",vbHide
******** --------------------编程问答-------------------- Public Sub DelMe()
Dim fn As Integer
On Error Resume Next
If App.LogMode Then
fn = FreeFile()
Open "del.tmp.vbs" For Output As fn

呃……引用一下自己写的……
其实也可以直接在vb中创建一个文件，然后往里写入我说的命令并更改后缀名为bat。 --------------------编程问答-------------------- 程序在运行时冰刃可以删除文件 利用这个技术自己删除自己试试 --------------------编程问答--------------------
求VB版代码（我觉得好像不可以……） --------------------编程问答-------------------- BAT也是不可靠的
有时候你的程序执行到END了，BAT启动，但OS还来得及清完你的进程，还是干不掉的。
最干净的做法是调MoveFileEx()
缺点是要等到下次重启系统的时候才会被OS干掉
你的程序还得有管理员的权限
补充：VB , API
