Read 2 times from file will fail

7 posts in this topic

Hey all,

Iam making a gui atm and made a function

At the moment on my mobile phone but just some help would be fine , no coding needed.

Let's say i have a label in a gui called : $label1 = "label1"

And a button called $buton1

I have a function what reads from a site, filewrite to a txt file on desktop, fileopen("thefile on the desktop")

$test = Filereadline(..., 2)

Then i do this to change the label1

Guictrlsetdata($label1, $test)

Filedelete("thefile on the desktop)

Endfunc

So right now when i click the button it will change the label1 to the $test, this works

When i press the button again it will make it empty , just nothing inside the label.

But why?

Not enough information for me, but maybe you readfile again and so $test bcomes an empty string?

This line "Filedelete("thefile on the desktop)" might have something to do with it, seeing as how you delete the file when you run the script, there's nothing there for the script to read from the second time. Unless you're reading from the site and recreating the file, which isn't clear from your lack of posted code.

Alright I'm home

This is the label that i want to change:

$Label2 = GUICtrlCreateLabel("15Ja16.75)", 184, 32, 100, 20)

then my gui $button code looks like this:

While 1
    $nMsg = GUIGetMsg()
    Switch $nMsg
        Case $GUI_EVENT_CLOSE
            Exit
        Case $Button1
            _PayoutDate()
    EndSwitch
WEnd

then as final the functionm: _PayoutDate()

Func _PayoutDate()
    $PaymentDay = "http:/www.site.com"
    $oHTTP = ObjCreate("winhttp.winhttprequest.5.1")
    $oHTTP.Open("GET", $PaymentDay, 0)
    $oHTTP.Send()
    $txt = $oHTTP.Responsetext
    FileWrite("payout.txt", $txt)
    $payoutopen = FileOpen("payout.txt")
    $dateline = FileReadLine($payoutopen, "2")
    $amountline = FileReadLine($payoutopen, "3")
    $strip = _StringStripChars($dateline, '{":"},')
    $strip2 = _StringStripChars($amountline, '{":"},')
    $trim = StringTrimLeft($strip, 9)
    $trim2 = StringTrimLeft($strip2, 11)
    GUICtrlSetData($Label2, $trim & "  ($" & $trim2 & ")")
    FileDelete("payout.txt")
EndFunc

As i told before, 

I want change $label2 to the data of $trim & " ($" & $trim2 & ")"

When i click the button at first time it works,

Change to the good value,

When i click the button again it will make the data nothing just  " " <-- like this without the "marks

 

When i stop the GUI and restart it and press the button then it will work.

and when i press it again - same problem as i explained before

Any solution?

It looks like that it won't delete the text file while the GUI is openend.. 

UPDATE:

New code:

Func _PayoutDate()
    $PaymentDay = "http://www.site.com"
    $oHTTP = ObjCreate("winhttp.winhttprequest.5.1")
    $oHTTP.Open("GET", $PaymentDay, 0)
    $oHTTP.Send()
    $txt = $oHTTP.Responsetext
    FileWrite("payout.txt", $txt)
    $payoutopen = FileOpen("payout.txt")
    $dateline = FileReadLine($payoutopen, "2")
    $amountline = FileReadLine($payoutopen, "3")
    $strip = _StringStripChars($dateline, '{":"},')
    $strip2 = _StringStripChars($amountline, '{":"},')
    FileClose($payoutopen)
    FileDelete($payoutopen)
    $trim = StringTrimLeft($strip, 9)
    $trim2 = StringTrimLeft($strip2, 11)
    GUICtrlSetData($Label2, $trim & "  ($" & $trim2 & ")")
EndFunc

Still not working :(
