I'm trying to convert a program from Linux to use on Windows, and it calls test -f, or test -d on Linux. I need it to do the same thing on Windows. Is there a built-in command, or another program I can use to do the same thing?
I'm programming using FreeBASIC (horrible, but it's what I got).
EDIT: An external program is the best option here. I've looked at the API, and it's not good.
Never heard of FreeBasic before but looking at the help there's a DIR command that supports using fbDirectory as one of the attribute patterns to filter for.
And looking slightly further down on that page I just saw that they have a sample for checking if the objects found are files or directories. Just look here, look at the second example on that page.
Not sure what exactly those test commands do, but if you want to test if a specific object is a directory you should be able to call Dir("exactname", fbDirectory, something) I'd thought. And then you could test for a file by putting a Not in somewhere (assuming that FreeBasic supports that).
Edit: To make your own tool, here's a sample that shows a tiny C++ app that could easily be changed to look for directories or not. Look for the FindFirstFile in the sample and shortly after that it checks if it's readonly, which could be changed for FILE_ATTRIBUTE_DIRECTORY.
http://unxutils.sourceforge.net/
you can use test.exe just like under linux
Not sure about FreeBASIC, have you looked into vbscript? You could use the FileSystemObject
Dim fso, msg
Set fso = CreateObject("Scripting.FileSystemObject")
If (fso.FolderExists(fldr)) Then
'Do Something here
Else
'Do Something
End If
If (fso.FileExists(filespec)) Then
'Do Something here
Else
'Do Something
End If
You can also use Kiwi for FreeBasic in order to check if a path leads to a file or directory. You can find Kiwi on Github (https://github.com/nsiatras/kiwi)
#include once "kiwi\kiwi.bi"
#include once "kiwi\io.bi"
' Declare a new file
Dim myFile as File = File("C:\Users\nsiat\Desktop\Test.txt")
' Check if file exists, is a File or is a Directory
print "File exists: " & myFile.exists()
print "Is file: " & myFile.isFile()
print "Is Directory: " & myFile.isDirectory()

I am a Java programmer, and I do not know anything about VBScript. I needed a way to modify the target path of a certain shortcut, and I according to my research, only VBScript can help me. I tried it, but there were many errors.
I tried to resolve them by a butt ton of googling, but I think there is some other problem.
Here is the code:
Set sh = CreateObject("WScript.Shell")
Set shortcut = sh.CreateShortcut("C:\Users\pedne\Desktop\Zoom.lnk")
shortcut.TargetPath = "C:\Users\pedne\AppData\Roaming\Zoom\bin\Zoom.exe ""--url=zoommtg\://zoom.us/join?action=join&confno=955 1234 1234&pwd=12345"""
shortcut.Save
I do not know whether I need any prerequisites or external libraries for writing VBScript code, and I wrote it on notepad.I would also like to know whether there is any 100% Java or any other workaround to this. (Totally up to you)
Please excuse me if I do not understand anything about your answers as I copied the code from Change a shortcut's target from command prompt
The last error I got was at Line 3 char 1, Invalid procedure or call
Do not append the arguments to the target path. Use the Arguments property instead:
shortcut.TargetPath = "C:\Users\pedne\AppData\Roaming\Zoom\bin\Zoom.exe"
shortcut.Arguments = "--url=zoommtg\://zoom.us/join?action=join&confno=955 1234 1234&pwd=12345"
shortcut.Save
Using this perl code below, I try to output some names in a random generated file. But the files are created with weird characters like this:
"snp-list-boo.dwjEUq5Wu^J.txt"
And, obviously when my code looks for these files it says not such file. Also, when I try open the files using "vi", they open like this
vi 'temporary-files/snp-list-boo.dwjEUq5Wu
.txt'
i.e. with a "new line" in the file name. Someone please help me understand and solve this weird issue. Thanks much!
code:
my $tfile = `mktemp boo.XXXXXXXXX`;
my $fh = "";
foreach my $keys (keys %POS_HASH){
open ($fh, '>>', "temporary-files/snp-list-$tfile.txt");
print $fh "$keys $POS_HASH{$keys}\n";
close $fh;
}
mktemp returns a line feed character in its output that you need to chop() or chomp() first.
Instead of using the external mktemp program, why don't you go with File::Temp instead?
Using external programs unnecessarily is a bad idea for a few reasons.
The external program that you use might not be available on all of the systems where your code runs. You are therefore making your program less portable.
Spawning a new sub-shell to run an external program is a lot slower than just doing the work in your current environment.
The values you get back from the external program are likely to have a newline character attached. And you might forget to remove it.
It's the last one that is burning you here. But the others still apply as well.
Perl's standard library has, for many, many years included the File::Temp module which creates temporary files for you without the need to use an external program.
use File::Temp qw/ tempfile /;
# It even opens it and gives you the filehandle.
($fh, $filename) = tempfile();
So I am trying to compile Pascal programs and everything is find; however, I would like to put the generated files after each compilation is a separated folder. I am looking of something like this: fpc "Destination Folder" "program.pas".
Thanks
From Alphabetical listing of command line options
-FE<x> Set exe/unit output path to <x>
-FU<x> Set unit output path to <x>, overrides -FE
So something like fpc program.pas -FEc:\output should work. I don't have fpc installed so I cannot verify. If you try it and get errors that you can't work through post them.
This one works for me:
fpc hello.pas -o"Web/hello.cgi"
I was using ubuntu, notice there is no space between the argument -o and the beginning of the path "Web/..."
I have attempted to follow the instructions on this post but I am falling short of understanding how some of the posters instructions work.
I want to be able to package the app with a prewritten bash script and then execute it, but don't follow from Step 4 onwards.
Post writes:
4. Also in your AppleScriptObjC script, add the following where appropriate:
property pathToResources : "NSString" -- works if added before script command
5. Where appropriate, also add the following in your AppleScriptObjC script:
set yourScript to pathToResources & "/yourScriptFile.sh"
-- gives the complete unix path
-- if needed, you can convert this to the Apple style path:
set yourScriptPath to (((yourScript as text) as POSIX file) as alias)`
6. As an aside, you could then open the file for read using
tell application "Finder"
open yourScriptPath
end tell
Questions:
Where do I add the line:
property pathToResources : "NSString"
Do I add which of the following, and where?
set yourScript to pathToResources & "/yourScriptFile.sh"
OR
set yourScriptPath to (((yourScript as text) as POSIX file) as alias)
How is it possible to execute the script itself? The mention As an aside, you could then open the file for read using only covers the Apple style path, it does not cover using the aforementioned style.
Can anyone shed a bit more light on this for me, or post a static copy of a AppDelegate.applescript file that shows how the original poster required the base code to be used? I have tried his method and looked across the internet for the past 3 weeks to no avail. I don't want to have to convert all my code for specific tools from bash scripts into AppleScript, as this would take a lot of work.
I only need to know how to reference to the script file (for example myBashScript.sh) in my app, which would reside in the application and be included by Xcode at time of compilation.
I think you should use the command path to resource <specifiedResource>.
See Standard Additions, path to resource.
You could set it by set myVariableName to path to resource "myBashScript.sh" or just use the command instead of your property so it points always to the right place (a user could move your app while running... lol).
ADDITION:
I did it that way in my AppleScript-Application:
on run_scriptfile(this_scriptfile)
try
set the script_file to path to resource this_scriptfile
return (run script script_file)
end try
return false
end run_scriptfile
Whenever I want to run a script that is bundled within my app I do this:
if my run_scriptfile("TestScript.scpt") is false then error number -128
run_scriptfile(this_scriptfile) returns true when everything worked.
I ended up bringing all the information together and now have a solution.
This takes into consideration the following facts:
firstScript = variable name that points to a script called scriptNumberOne.sh
scriptNumberOne.sh = the script that I have embedded into my application to run
ButtonHandlerRunScript_ = the name of the Received Action in Xcode
pathToResources = variable that points to the internal Resources folder of my application, regardless of it's current location
Using this information, below is a copy of a vanilla AppDelegate.applescript in my AppleScriptObjC Xcode project:
script AppDelegate
property parent : class "NSObject"
property pathToResources : "NSString"
on applicationWillFinishLaunching_(aNotification)
set pathToResources to (current application's class "NSBundle"'s mainBundle()'s resourcePath()) as string
end applicationWillFinishLaunching_
on ButtonHandlerRunScript_(sender)
set firstScript to pathToResources & "/scriptNumberOne.sh"
do shell script firstScript
end ButtonHandlerRunScript_
on applicationShouldTerminate_(sender)
-- Insert code here to do any housekeeping before your application quits
return current application's NSTerminateNow
end applicationShouldTerminate_
end script
I have written following code in vb.net to delete the file.
If File.Exists(strPath & "\ReportEng.ini") = True Then
File.SetAttributes(strPath & "\ReportEng.ini", FileAttributes.Normal)
File.Delete(strPath & "\ReportEng.ini")
End If
File.Copy("\\192.168.0.1\SAP_Shared\AddonExtra\ReportEng.ini", strPath & "\ReportEng.ini")
This code works perfectly in windows xp. But in Windows 7,I can not delete it. This OS is hectic OS from developer's point of view. Some or other problem occurs and Microsoft has not considered the developer while building this OS.
How do I delete file in Windows 7 ?
It's so easy to do so;
If My.Computer.FileSystem.FileExists("C:\somefile.ext") Then 'Check whether file exists
My.Computer.FileSystem.DeleteFile("C:\somefile.ext") 'Delete the file!
End If
Have a nice day!
You don't need to delete the file: there is an overload File.Copy Method (String, String, Boolean) which allows overwriting.
You didn't say what error you get. I suspect it is because the user doesn't have write access to the directory. You should probably be using a subdirectory of the directory returned by Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData) or maybe .LocalApplicationData, and definitely not the directory containing the program.
Also, using Path.Combine(strPath, "ReportEng.ini") is how you're meant to combine paths - it'll take care of, e.g., the trailing path separator for you.
The preferred method for interfacing with the Windows file system uses the following namespace:
Imports Microsoft.VisualBasic.FileIO.FileSystem
To delete a file:
Dim FileLocation As String = strPath & "\ReportEng.ini"
If Not GetDirectoryInfo(FileLocation).Exists Then
GetFileInfo(FileLocation).Delete()
End If
