求助：有关其他程序的调用问题

[addone]

请问列位高手，如何在程序中调用其他程序？并且可以指定目标程序的工作目录 ？并且可以获得目标程序的进程ID？SHELL（）和SHELLEXECUTE（）均不够。那么如何使用SHELLEXECUTEEX（）？最好给出源代码。谢谢。

lpDirectory参数！


ShellExecute

VB声明
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
说明
查找与指定文件关联在一起的程序的文件名
返回值
Long，非零表示成功，零表示失败。会设置GetLastError
参数表
参数 类型及说明
hwnd Long，指定一个窗口的句柄，有时候，windows程序有必要在创建自己的主窗口前显示一个消息框
lpOperation String，指定字串“open”来打开lpFlie文档，或指定“Print”来打印它
lpFile String，想用关联程序打印或打开一个程序名或文件名
lpParameters String，如lpszFlie是可执行文件，则这个字串包含传递给执行程序的参数
lpDirectory String，想使用的完整路径
nShowCmd Long，定义了如何显示启动程序的常数值。参考ShowWindow函数的nCmdShow参数

实在不行用CreateProcess
