Android Question Minor IDE bug?

RB Smissaert · Feb 13, 2021

B4X:

Wait For (File.CopyAsync(File.DirRootExternal & "/PhonePats/", strMainDBName, Starter.strSD_DB_Dir, strMainDBName)) _
        Complete (bSuccess As Boolean)

Where strDBName is a string variable in Main Sub Process_Globals()
For some reason strMainDBName is not highlighted (purple) in the above code.

Otherwise it shows fine highlighted eg:

B4X:

lblFileCopy.Text = "Copying DB, " & strMainDBName & " (" & strFileSize & ") ..."

The highlighter does not parse code. Only literal strings are highlighted, variable names are not.

Ok, but then why does for it for example highlight if you do:

B4X:

Round(strDBName)

This might one of the few cases where it's actually appropriate to post code as a screenshot.

As far as I can see it doesn't unless you omit the declaration in which case it is highlighting it as an error, not because it is a string

Attached a screenshot.

If it's a screenshot why is it in a docx file?

EDIT: OK I opened it with WordPad as I'm nervous as hell about docx and doc files. That's not a String highlight it's a Global variable highlight. It will do it regardless of type.

I misunderstood, I thought you were expecting the variable name to be highlighted like a String because it was a String variable. Yes I agree, it does not highlight within the WaitFor so it does look like a bug!

Indeed.
Will find a better way to post images for next time.

I just drag them on to the compose panel and resize them there.

I just use the "printscreen" key and past it in place and resize as needed

Something like this will work. See working code and screenshot that shows the purple

B4X:

Public str1name As String ="andrewOne.txt"  'Process_Globals
Public str2name As String ="andrewTwo.txt"

B4X:

Dim sf As Object = File.CopyAsync(File.DirInternal, str1name, File.DirInternal, str2name)
    Wait For (sf) Complete (Success As Boolean)
    If Success Then
        Log("file was successfully copied")
    Else
        Log("Sorry, file copy failed")
    End If

Yes, that highlights the variable, but no need to declare the variable Public and no need to assign an initial string.

The important thing is: Does it do the job in copying the file and give you the purple color you were looking for. That is more important than the variables declaration because I do not know the rest of your code. The declaration was just there just to have variables.

You confused me initially by thinking the variable needed to be Public and have an initial value assigned.
The only thing that made the difference is how the Wait For is coded.

The code I posted is more general and I was not specifically addressing your issue. It is out there in case someone needs to test.
