As soon as I try to access a folder/file containing an emoji in its name from my Lua 5.2 script, for example like this:
os.execute('start "" "' .. path .. "\\scripts\\menu\\📄 My Scripts" .. '"')
The Windows' Command Prompt simply refuses to open it with the following error message:
I'm aware Windows' Command Prompt doesn't support emojis and therefore is not possible to make it work just like that, but my doubt is if won't exist some workaround or whatever I can do to ensure any Windows/Unix user is going to able to get the folder open by my Lua script without any problem.
I have tried i.e. things like use the codes instead (1246 and U+1F4F0 in this page facing up case) without success. Couldn't I for example simply use some kind of "wildcard" instead? I mean, knowing it's always going to be the very first character in the name. Or, well, any other ideas will be welcomed, cause nothing I'm trying really seems to work...
Of course if it's going to represent any problem I'll simply refuse to use them, but it came in handy for some "first sight" folder distinction and, if possible, I'd like to can count this little visual resource 🙄
This is a Problem about how the string is constructed.
I found only one solution with [[command "path"]] (on Windows 11 and Lua 5.3)...
os.execute([[start ]] .. path .. [["\scripts\menu\📄 My Scripts"]])
-- My Testpath is/was: os.execute([[dir "%localappdata%\nvim\📄 Lua"]])
...the long string ([[]]) will not be interpreted (coercionated) by Lua.
That also have the side effect that you can use single backslashs with that kind of string.
Environment variable expansion (e.g. Windows: %localappdata%) only works inside doublequotes.
Single quotes instead ([[command '%localappdate%\path\']]) will not work (expanded).
os.execute accepts only ANSI-encoded strings (win-1252 in European Windows), but it is unable to encode an emoji.
Hint: you can create .bat-file to do the task for you and invoke it from Lua with os.execute.
I know there are similar articles like PDF file conversion in JMeter but they do not answer the actual problem which is "when converting a PDF to a variable/object/property then back to PDF the document whilst the correct number of pages is 'whit on white'= blank.
is there a way to :
Create a runtime variable/object/property from an existing PDF file that can be used in a subsequent action.
Here other actions happen in the Test Plan but they do not
Convert the variable/object/property back to a pdf so that when viewed it does not contain just blanks.
Notes: I do not just wish to just copy a to pdf to pdf.
I have also tried creating a UDV form the pdf using the following posted on here without success too.
${__groovy(vars.putObject("hoping_its_a_pdf"), new File("my_original.pdf"))}
Reading other posts here I have also noticed strange character strings like "%âãÏÓ" when using both putObect and props.put when viewing them post creation but as the article said, most probably page break characters or similar so I have ignored those for now as I assumed it is the conversion and not the reason for the blank content.
Can someone please assist as this is now 4 weeks in and I still have white pdf's.
We cannot state what's wrong with the code which you're copying and pasting from some random sources.
There is not problem with storing the PDF file in JMeter Variables or properties and creating the file back from them.
Demo:
There are 2 problems the only piece of "code" you're sharing:
Your way of using vars.putObject() function is wrong, it takes 2 parameters: variable name and the object value. See Top 8 JMeter Java Classes You Should Be Using with Groovy article for more information on this and other JMeter API shorthands
Apart from this the function itself is syntactically incorrect, you need to escape any comma in the function with a backslash
So if you change your:
${__groovy(vars.putObject("hoping_its_a_pdf"), new File("my_original.pdf"))}
to
${__groovy(vars.putObject('hoping_its_a_pdf'\, new File('my_original.pdf')),)}
at least this bit will start working as you expect.
Could someone please help me create a path for an image that I am displaying in the image box? This tool is intended for use of others. Therefore, they will have to download it in their computers and the path to the image will change. I have tried several ways but nothing seems to work. Here is the code:
Me.cmdImage2.Picture = LoadPicture("G:\Pedestrian Bridges\New folder with organization\Visual Basic Tool\Tool\New folder\TRB paper Version\Imagenes Finales\Alternative 2.JPG")
Thanks a lot!!!!!!!!!!
Try thisworkbook.path or activeworkbook.path it will be saved the image in same folder
This is a good question and something I've been recently working on. I will show you a few lines of my code that would be beneficial for you to use as well.
The first potential method you could use would be to implement the IO class's ability to return the path your application is being run from. You can do that by following this example:
MessageBox.Show(IO.Path.Combine(IO.Directory.GetParent(Application.ExecutablePath).FullName, "myimage.jpg"))
Another potential solution would be to use environmental variables.
In order to do this you will need to import the IO class:
using System.IO;
Then you can reference environmental variables like this:
DirectoryInfo dst = new DirectoryInfo(Environment.GetEnvironmentVariable("UserProfile") + #"\Desktop\!#!Desktop_Cleanup\" + s + #"_Desktop\" + category);
Sorters.CopyFiles(src, dst, true, "*."+ extension);
In my example, I'm using the UserProfile enviromental variable that is stored in Windows. Then, knowing where that path leads I am able to add a path to a file system on my desktop that I use for cleaning the desktop. Keep in mind you will need to use the # symbol before strings containing backslashes so they will be read properly and not as escape characters.
Sorters is a class that I made and won't be applicable in your application, but I included that line so you could see a possible implementation of the DirectoryInfo you create.
Hope this helps!
This is more of a curiosity than actual problem as there is an easy and propably more preferable workaround. When using Codeigniters form validation and when displaying error message the CI user guide gives two ways to set one's own validation messages: through set_message-method and editing the language file which is located in the system folder.
However when editing the language file to contain error messages in my native language (which contains special character liks 'Ä' and 'Ö') the special characters are replaced with a black diamond. When using the set_message-method from form_validation it works without a problem and the characters are encoded with UTF-8 properly.
I am wondering where lies the problem when using the file instead of the method and how to solve it?
It sounds like the file is not saved by your editor as UTF-8. Make sure that it is.

When using the registry to associate file extensions and application, I put in the full filename of my application, but that does not work well, only if I use the 8.3 filename.
for example ( taken from the registry) this works:
[HKEY_CLASSES_ROOT\Toto.Document\shell\myVerb\command]
#="C:\\my\\path\\bin\\Debug\\bin\\myexe_~1.EXE /dde"
[HKEY_CLASSES_ROOT\Toto.Document\shell\myVerb\ddeexec]
#="[myVerb(\"%1\")]"
but this does not work :
[HKEY_CLASSES_ROOT\Toto.Document\shell\myVerb\command]
#="C:\\my\\path\\bin\\Debug\\bin\\myexecutable.EXE /dde"
[HKEY_CLASSES_ROOT\Toto.Document\shell\myVerb\ddeexec]
#="[myVerb(\"%1\")]"
The action is called by right-clicking on the file in Explorer, I get the error :
"Windows cannot find 'c:\users\me\desktop\tata.toto'. Make sure you typed the name correctly, and then try again".
I'm creating the keys programatically with CRegKey and using GetModuleFileName to get the application path.
2 questions :
- I'm probably missing something in my registry entry ? (i've tried quoting the paths, but does not work)
- Can I get the "short" filename ? (searching a little bit seems that GetShortPath should work, but not always!)
Thanks.
Max.
(edit 22/03/2011)
I tried using quotes but it did not work (with /dde)
I decided to use normal parameters instead of /dde and it seems to work nicely with the normal path (not shortened like stated above).
I'm still not certain why when creating a simple MFC SDI project it will write out registry values with the old short name instead of the long name.
Thanks again.
Max.
Try creating the key with another couple of double-quotes (note between .EXE and /dde:
#="C:\\my\\path\\bin\\Debug\\bin\\myexecutable.EXE" "/dde"
