The property Environment.CurrentDirectory always returns the path of system directory instead my application directory. In my colleague's PC, it returns application directory.
What is the problem? How can I solve it?
The following code is working for me
ePCRSettings = XMLParser.XmlParser.Deserialize<PCRGeneratorSettings>(string.Format("{0}\\ePCRPDFSettings.xml", AppDomain.CurrentDomain.BaseDirectory));
AppDomain.CurrentDomain.BaseDirectory - Returns the directory E:\MyApplications\.
The following code is not working for me
ePCRSettings = XMLParser.XmlParser.Deserialize<PCRGeneratorSettings>(string.Format("{0}\\ePCRPDFSettings.xml", Environment.CurrentDirectory));
Environment.CurrentDirectory - Returns c:\windows\system32.
This .dll file can be used in VB 6 and ASP.NET applications
set current directory
Directory.SetCurrentDirectory(AppDomain.CurrentDomain.BaseDirectory); //or set executing Assembly location path in param
Environment.CurrentDirectory //now returns your app path
Use
System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetEntryAssembly().Location);
You shouldn't be using the Environment.CurrentDirectory value as a base for file lookups because it can change and may not always be under your control. e.g. a File Save As to a different folder may change the 'current folder' value. As you can see it can yield unpredictable results.
Use a value that you can control better. e.g. a ResourcesFolderPath value in a configuration (xml?) file that is updated when you install your app.
I suspect that this could have something to do with the current user id that the app is running under, for example if you are running the app in a user session (e.g. debugging in VS) then this may return your current directory, but if you were running it under IIS then this could be why it is defaulting to the system folder?

I've got the file "updates.exe", which runs a program. When this file is executed, I might see the next info:
Program Started 101.0.4951.41 version. etc.
How to get the version value '101.0.4951.41' ?
I need to put it to a variable and use it in my further actions.
$CurrentVersion = 101.0.4951.41
Like this.
Thanks!
When starting Netbeans, I need to add a system property named mEnvironment and set it as a sub-directory of the user's home. Example: In the netbeans.conf, I would like to add:
netbeans_default_options="-J-XX:+UseStringDeduplication -J-Xss2m -J-DmEnvironment=${USER_HOME}/mySubDirectory ......
USER_HOME is given as example of course.
Does someone know how Netbeans get the user home directory in the netbeans.conf file?
Thank you

Does someone know how Netbeans get the user home directory in the
netbeans.conf file?
The process is convoluted, and varies by operating system, but is described in great detail within netbeans.conf itself. This is the relevant content for my Apache NetBeans 11.1 installation:
# On Windows ${DEFAULT_USERDIR_ROOT} will be replaced by the launcher
# with "<AppData>\NetBeans" where <AppData> is user's
# value of "AppData" key in Windows Registry under
# "HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders"
# and ${DEFAULT_CACHEDIR_ROOT} will be replaced by the launcher
# with "<Local AppData>\NetBeans\Cache" where <Local AppData> is user's
# value of "Local AppData" key in Windows Registry under
# "HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders"
#
# On Mac ${DEFAULT_USERDIR_ROOT} will be replaced by the launcher
# with "~/Library/Application Support/NetBeans" and
# ${DEFAULT_CACHEDIR_ROOT} with "~/Library/Caches/NetBeans"
#
# On other systems ${DEFAULT_USERDIR_ROOT} will be replaced by the launcher
# with "~/.netbeans" and ${DEFAULT_CACHEDIR_ROOT} with "~/.cache/netbeans"
....
netbeans_default_userdir="${DEFAULT_USERDIR_ROOT}/11.1"
However, none of that really helps you, because you cannot access the values of netbeans_default_userdir or DEFAULT_USERDIR_ROOT; they are used internally by NetBeans itself, and are not System properties. You can verify this by displaying the values returned by System.getProperties(); none of the entries in netbeans.conf are shown.
Also, you can't meaningfully add new name/value pairs in netbeans.conf; you can only modify the values of the names used by NetBeans. That file is for NetBeans configuration, not user configuration. So if you add a line containing (say) MyConfSetting="ABC" then NetBeans will simply ignore that, and it won't be accessible to you either.
However, you can use an alternative approach to set a System Property for your directory in your application:
The read-only environment variable APPDATA points to your (operating system's) user directory. On my Windows 10 machine it has the value C:\Users\johndoe\AppData\Roaming.
The default user directory for NetBeans is the value of APPDATA + a sub-directory named NetBeans + a sub-directory named the NetBeans version. On my machine it is C:\Users\johndoe\AppData\Roaming\NetBeans\11.1. See the value of User directory in the Help > About screen for confirmation.
I don't know how to dynamically determine the version of NetBeans, but if that isn't important you can programmatically create a system property specifying your directory path:
String dir = System.getenv("APPDATA") + "\\NetBeans\\mySubDirectory";
System.setProperty("myDir", dir);
System.out.println("myDir=" + System.getProperty("myDir"));
On my machine that println() call displays myDir=C:\Users\johndoe\AppData\Roaming\NetBeans\mySubDirectory. I don't know if that approach meets your requirements, but I don't know of any other simple way to dynamically set your directory name.
Notes:
I checked this on Windows 10. Details may vary on other operating systems, but the overall approach should still work.
You can also specify parameters at run time using {project} > Properties > Run > Arguments (e.g. arg1=%APPDATA%\NetBeans\MyDir) and {project} > Properties > Run > VM Options (e.g. -Dvmopt1=%APPDATA%\NetBeans\MyDir), but that approach won't work because the %APPDATA% is simply treated as the literal "%APPDATA%" rather than evaluated as an environment variable.
I'm using Sphinx on a Linux production server as well as a Windows dev machine running WampServer.
The index configurations in sphinx.conf each require a path setting for the output file name. Because the filesystems on the production server and dev machine are different, I have to have two lines and then comment one out depending on which server I'm using.
#path = /path/to/folder/name #LIVE
path = C:\wamp\www\site\path\to\folder\name #LOCALHOST
Since I have lots of indexes, it gets really old having to constantly comment and uncomment dozens of lines every time I need to update the file.
Using relative paths would be the ideal solution, but when I tried that I received the following error when running the indexer:
FATAL: failed to open ../folder/name.tmp.spl: Invalid argument, will not index. Try --rotate option.
Is it possible to use relative paths in sphinx.conf?
You can use relative paths, but its kind of tricky because you the various utilities will have different working directories.
eg On windows the searchd service, will start IIRC with a working directory of $WINDIR$\System32
on linux, via crontab, I think it has working directory left over from previously, so would have to change the folder in the actual command line
... ie its not relative to the config file, its relative to the current working directory.
Personally I use a version control system (SVN actually) to manage it. The version from Dev, is always the one commited to the repository, the 'working copy' on the LIVE server, has had the paths edited to the right location. So when 'update' to the latest file, only changes are merged leaving the local filepaths in tact.
Other people use a dynamic config file. The config file can be a script (php/python/perl etc) - but this only works on linux so wont help you.
Or can just have a 'publish' script. Basically, you edit a 'master' config file, and one that can be freely copied to all servers. Then a 'publish' script, that writes the apprirate local path. It could do it with some pretty simple search replace.
<?php
if (trim(`hostname`) == 'live') {
$path = '/path/to/folder/';
} else {
$path = 'C:\wamp\www\site\path\to\folder\`;
}
$contents = file_get_contents('sphinx.conf.master');
$contents = str_replace('$path',$path,$contents);
file_put_contents('sphinx.conf',$contents);
Then have path = $path\name in the master config file, which will get replaced to the proper path, when run the script on the local machine
I got the following error while starting JBoss from a command line prompt today:
'findstr' is not recognized as an internal or external command
Please google it, you can find a lot of answers. But do as below to fix it. Add the following value to Right Click My Compuer -> Advanced -> Environment Variables -> System Variables -> Select Path variable -> append the below value.
C:\WINDOWS\system32
It should work with that change.
As others pointed, issue is in wrong settings of PATH variable in Windows.
According to article this is most probably because some stupid installer wrongly modified PATH variable in Windows registry. Registry has 2 different string value types - REG_SZ and REG_EXPAND_SZ. Only the second one allows for expansion of %SystemRoot%.
So check your path by typing set path in command prompt. If you see unexpanded %SystemRoot% and other variables in Path, you are affected (PATH should show only plain directory names, not variables).
You need to edit Path variable in registry: HKEY_CURRENT_USER\Environment and HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment. As it is not possible to change the type of key, save the path value somewhere, delete the key and re-create it with type REG_EXPAND_SZ. You need to logout for changes to take effect.
for me it works when I've coped findstr(from windows/system32) to wildfly/bin
Please go throught the simplest steps:-
go to C:\Windows\system32\ and copy findstr.exe file.
paste this file into the location C:\Program Files\Java\jdk1.6.0_24\bin
Run your jboss again you will get out of this.....
Check to see if you %SystemRoot% is evaluating (type set path into a command prompt, you should not see %SystemRoot%, but instead that actual path). If your path variable's (user, or systems) first entry begins with an %(an environment variable) this can cause an issue.
To resolve this, simply swap this first entry with anything else in your path that does not lead with an environment variable.
You can also hard code the directory by replacing 'findstr' with 'C:\Windows\system32\findstr'. This is useful when using systems with restricted user permissions.
I have try to work with play framework but stuck with to run activator.bat file but solution is the same just copy file from windows/system32/findsr and past it to under stuck folder then run the respective file again.
thanks to andrewsiand Suryaprakash
Please beware that current Windows systems use a Capital "S" for the System directory, so:
C:\WINDOWS\System32
%SystemRoot%\System32
Omitting the capital S will result in a neglect of the line in the %PATH%
In my case (not JBoss related) the following helped to fixed this error.
Instead of:
SET path="%path%;C:\some\additional\path"
I used:
SET "path=%path%;C:\some\additional\path"
For IBM ACE solution for
'findstr' is not recognized as an internal or external command,
Go to the path C:\Windows\System32
Find the findstr.exe, copy it and then find the path where you bin file of your application is found. eg C:\Program Files\IBM\ACE\11.0.0.12\server\bin then past it inside the bin file
cancel the console of ace and re-open it.
Then run ACE toolkit command on ace console.
Then press enter, now it can open.
On all my Windows servers, except for one machine, when I execute the following code to allocate a temporary files folder:
use CGI;
my $tmpfile = new CGITempFile(1);
print "tmpfile='", $tmpfile->as_string(), "'\n";
The variable $tmpfile is assigned the value '.\CGItemp1' and this is what I want. But on one of my servers it's incorrectly set to C:\temp\CGItemp1.
All the servers are running Windows 2003 Standard Edition, IIS6 and ActivePerl 5.8.8.822 (upgrading to later version of Perl not an option). The result is always the same when running a script from the command line or in IIS as a CGI script (where scriptmap .pl = c:\perl\bin\perl.exe "%s" %s).
How I can fix this Perl installation and force it to return '.\CGItemp1' by default?
I've even copied the whole Perl folder from one of the working servers to this machine but no joy.
#Hometoast:
I checked the 'TMP' and 'TEMP' environment variables and also $ENV{TMP} and $ENV{TEMP} and they're identical.
From command line they point to the user profile directory, for example:
C:\DOCUME~1\[USERNAME]\LOCALS~1\Temp\1
When run under IIS as a CGI script they both point to:
c:\windows\temp
In registry key HKEY_USERS/.DEFAULT/Environment, both servers have:
%USERPROFILE%\Local Settings\Temp
The ActiveState implementation of CGITempFile() is clearly using an alternative mechanism to determine how it should generate the temporary folder.
#Ranguard:
The real problem is with the CGI.pm module and attachment handling. Whenever a file is uploaded to the site CGI.pm needs to store it somewhere temporary. To do this CGITempFile() is called within CGI.pm to allocate a temporary folder. So unfortunately I can't use File::Temp. Thanks anyway.
#Chris:
That helped a bunch. I did have a quick scan through the CGI.pm source earlier but your suggestion made me go back and look at it more studiously to understand the underlying algorithm. I got things working, but the oddest thing is that there was originally no c:\temp folder on the server.
To obtain a temporary fix I created a c:\temp folder and set the relevant permissions for the website's anonymous user account. But because this is a shared box I couldn't leave things that way, even though the temp files were being deleted. To cut a long story short, I renamed the c:\temp folder to something different and magically the correct '.\' folder path was being returned. I also noticed that the customer had enabled FrontPage extensions on the site, which removes write access for the anonymous user account on the website folders, so this permission needed re-applying. I'm still at a loss as to why at the start of this issue CGITempFile() was returning c:\temp, even though that folder didn't exist, and why it magically started working again.
The name of the temporary directory is held in $CGITempFile::TMPDIRECTORY and initialised in the find_tempdir function in CGI.pm.
The algorithm for choosing the temporary directory is described in the CGI.pm documentation (search for -private_tempfiles).
IIUC, if a C:\Temp folder exists on the server, CGI.pm will use it. If none of the directories checked in find_tempdir exist, then the current directory "." is used.
I hope this helps.
Not the direct answer to your question, but have you tried using File::Temp?
It is specifically designed to work on any OS.
If you're running this script as you, check the %TEMP% environment variable to see if if it differs.
If IIS is executing, check the values in registry for TMP and TEMP under
HKEY_USERS/.DEFAULT/Environment
