How to get the path of a file object? Topic is solved

[JackMa]

I want to get the path of the file object. I have tried to search for "path" in the help file of the file object and search for relevant keywords on Google, but I did not find a satisfactory answer.

Does the file object have this method?

You would have needed the path to create the file object, correct? That would be the time where your script would know it and assign it to a variable if desired.

This is possible like this:

Code: Select all

filePath := "D:\MyFile.txt"
file := FileOpen(filePath, "r")
myPath := GetFilePathFromFileObject(file)
file.Close()
MsgBox, % myPath

GetFilePathFromFileObject(fileObj) {
   chars := DllCall("GetFinalPathNameByHandle", "Ptr", fileObj.__Handle, "Ptr", 0, "UInt", 0, "UInt", 0)
   VarSetCapacity(filePath, chars << !!A_IsUnicode, 0)
   DllCall("GetFinalPathNameByHandle", "Ptr", fileObj.__Handle, "Str", filePath, "UInt", chars, "UInt", 0)
   Return RegExReplace(filePath, "^\\\\\?\\")
}

Do you mean to store variables in advance?

Perfect solution to my problem, very good, thank you

I mean when you create the file object, it’s with a known path, right? So you could just capture the path at that point by saving it to a variable. Not sure whether you consider that in advance or not.

I have considered that this operation is obvious. Next time I ask a question, I will write the known methods.

A lot of people post questions and have overlooked the most straightforward solutions, so it's worth mentioning. Since you're new here, I don't know what you may have considered.

Code: Select all

file := "C:\TestFolder\test.txt"
Loop, %file%
    FilePath := A_LoopFileDir
    MsgBox, % FilePath

The text box should show "C:\testFolder".

I don't know if that's what you needed, but I'll leave it here, I was looking for a way to get the path without using regular expressions.
