Win32 :: Process ...目标问题 [英] Win32::Process ... target problem
问题描述
在玩''fork''以试图让一个进程监视另一个进程之后，我已经改变了我的方向并切换到了Win32： ：处理。实际上，看起来这个功能可以满足我的要求：
A：启动一个Windows应用程序
B：该应用程序定期运行监视日志文件
C：如果Windows应用程序崩溃或锁定，则监视进程将终止作业并干净地关闭脚本，并提供错误代码作为返回。
但是，我遇到了一些语法问题并发现虽然我可以使用Win32 :: Process :: Create来打开我需要的程序（在这个测试''notepad''中），我发现目标文件（此处：nptest.txt）将无法打开。我只是得到一个空白文本文件。
这是我的代码示例...
我的$ ProcessObj;
Win32 :: Process :: Create（$ ProcessObj，
" C：\\WINDOWS \\ system32 \\\\
otepad.exe"，
" C：\\Temp \\\\
ptest.txt"，
0，
NORMAL_PRIORITY_CLASS，
C：\\Temp或者死于ErrorReport（）;
我在路径中尝试了各种变化但是无法打开目标文件。我发现这个奇怪的是应用程序本身（记事本和其他Windows应用程序）打开正常...但不是目标。
这一定是一些简单的事情，我错过了但我有用网上的例子回来看看，我看不到它。也许第二双眼睛会看到我错过了什么？
或许你可以建议另一个命令/语法/过程让一个（重复）过程监视另一个（长）过程？
我会非常感谢您提供的任何提示或想法。
致敬和谢谢，
Alan Searle。

尝试使用wordpad测试。
Hallo everyone,
After playing around with ''fork'' in order to try to get a one process to monitor another, I have changed my tack and switched to Win32::Process. Indeed, it looks like this function will be able to do what I require:
A: Start a windows application
B: While that application is running regularly monitor a log file
C: If the windows application falls over or locks up, then the monitor process will kill the job and close the script cleanly, supplying an error code as return.
However, I am having some issues with the syntax and find that although I can use Win32::Process::Create to open the program I require (in this test ''notepad''), I find that the target file (here: nptest.txt) will not open. I just get a blank text document.
Here is a sample of my code ...
my $ProcessObj;
Win32::Process::Create($ProcessObj,
"C:\\WINDOWS\\system32\\notepad.exe",
"C:\\Temp\\nptest.txt",
0,
NORMAL_PRIORITY_CLASS,
"C:\\Temp") or die ErrorReport();
I have tried all kinds of variations in the path but couldn''t get it to open the target file. I find this bizarre as the application itself (notepad and other windows applications) opens fine ... but not the target.
It must be some simple thing that I have missed but I have checked back with examples from the web and I just can''t see it. Maybe a second pair of eyes will see what I have missed?
Or maybe you can suggest an alternative command/syntax/process for getting one (repeating) process to monitor another (long) process?
I''d be very grateful for any tips or thoughts that you have.
Regards and thanks,
Alan Searle.

try using wordpad for the test.
