[DONE] Writing to a file from a stringgadet

[PresFox]

Hello,

I have a stringgadget in my window, and i want to take the input from it and write it to a file.

I am not sure how to go about this.

I have tried this:

Code: Select all

Procedure Open_Window_1()
  If OpenWindow(#Window_1, 308, 114, 391, 76, "New window ( 1 )",  #PB_Window_SystemMenu | #PB_Window_SizeGadget | #PB_Window_TitleBar )
    If CreateGadgetList(WindowID(#Window_1))
      StringGadget(#String_0, 20, 10, 340, 30, newlander$)
      ButtonGadget(#Button_3, 290, 50, 70, 20, "add")
      
    EndIf
  EndIf
EndProcedure

and this is the in the main loop:

Code: Select all

 ElseIf GadgetID = #Button_3
    
    ; add a landing page to the list
    
    If OpenFile(0, "Landers.dat")    ; opens an existing file or creates one, if it doesn't exist yet
    FileSeek(0, Lof(0))         ; jump to the end of the file (result of Lof() is used)
    WriteStringN(0, newlander$)
    CloseFile(0)
  EndIf

The file gets created, but nothing is written in it?

As far as I can see there may be different mistakes, however I can only guess, because the code is not working.
Pleass post next time copy-able code which can be run immediatly.

1. newlander$ seems to be an empty string
2. #String_0, #Button_3 may have the same value

A very very useful command is by the way enable explicit. It forces you to declare every variable. At first it seems annoying, but you wont miss it in future.

Have you checked the value of the newlander$ string? (send it to the debug output window using 'Debug')

If you want the contents of the StringGadget you should use GetGadgetText().
For instance

Code: Select all

WriteStringN(0, GetGadgetText(#String_0))

You may be looking for GetGadgetText()?

Hi PresFox, welcome to the board

Just a note how to indicate that a question has been solved: just edit your first posting and write something like "[Done] " at the front of the subject...

Putting [Done] at the start just means better solutions (when possible) may be ignored, though. People with better solutions may just skip the thread. Something to be aware of. I wouldn't be so quick to close off future solutions to lurkers.
