Writing to a file

[Surgery]

Ok, here's the script snippet:

Local $path = FileOpenDialog("Find Launcher", "C:\", "Launcher (index.html)");
    Local $file = FileOpen("pointer.txt", 2);
    FileWriteLine($file, $path);
    MsgBox(0, "Status", $path);
    FileClose($file);

it writes the file location to the pointer.txt file fine if the file is in the same folder as the script executable. but if it isn't it just doesn't write anything, even though the msgbox prints out the correct path. It'd make a little more sense if the msgbox also printed nothing, but I don't understand why it isn't writing correctly. Thanks.

If your saying what I think you are, then it's because $path is written to pointer.txt if certain things are true. The MsgBox(), however, will appear no matter what. Does this help?

Ah, yes. You are right. However, I forgot to say that in my debugging I have tried capturing the result of the FileWriteLine call and MsgBoxing that, and I get 1. And when I open the file it was supposed to have written to either there is nothing there or there is no change.

Sorry to bump this, but this is a major problem, and if it's a language issue I'd like to know so I can move on and find another language.

When you choose a file in another folder the working directory is set to that folder. So when you open the file to write it will be created in that folder. You need to set the working directory back before you open the file to write.

Local $currentworkingdir = @WorkingDir
Local $path = FileOpenDialog("Find Launcher", "C:\", "Launcher (index.html)");
FileChangeDir($currentworkingdir)
Local $file = FileOpen("pointer.txt", 2);
FileWriteLine($file, $path);
MsgBox(0, "Status", $path);
FileClose($file);

EDIT Correct "file to read" to "file to write"

Aha! Thank you so much. That makes sense and it works perfectly now. And the project can move forward. Thanks again.
