Check if file exist and then take it from there...

[Roshith]

A function is never a variable.

A variable just stores some value

A function executes a set of commands and it may or may not return values.

Example: func add($a, $

return $a+$b

endfunc

Here Func add return the sum of variables a & b.

Just a word of caution, it will only return 1 if the ini file doesn't contain anything in the section specified in the the $section variable, and nothing in the key pointed to by $var. If it does contain something in them, you will get the value from the key and not 1 (unless that key holds the value of 1).

#include <WarUDF.au3>
$var = WarUdf(@AppDataDir & "\Program","test.ini","variable","section")
MsgBox(0,"",$var) ; first run through
iniwrite(@appdatadir & "\Program\test.ini", "section", "variable", "value")
$var = WarUdf(@AppDataDir & "\Program","test.ini","variable","section")
MsgBox(0,"",$var) ; second run through
Exit

Rewrote the green helpfile a touch

WarUdf.au3

Question:

Is it possible to turn it into part of the syntax?

Like this thing:

Edit: Didnt relise how big it was before posting...

@Roshith: I see, thanks for clearing that up!

@BrewManNH: So if the key holds 7 then it wont work ?

What if i add this before i return ?

If $read = 0 then
    $read = 0
Else
    $read = 1
EndIf

Wouldnt that work ?

Read up on "User Calltips" and "User UDFs syntax highlighting" in the SciTE4AutoIt3 helpfile.

[Maffe811]

Will do!

[BrewManNH]

In response to the popup tooltip you're asking about, look in the SciTE\api folder for a file called "au3.user.calltips.api", if it doesn't exist you can create a new one. Inside that file you'd create your new calltips, as they're called in SciTE, formatted something like this

_BASS_SetConfig($option, $value) Sets the value of a config option. (Requires: Bass.au3)

The red section is your function name and it's parameters, the green section is the desriptive text you want displayed when you start typing the function. The last section isn't needed, it just helps to remind users what include file is needed to use this function.

[Maffe811]

Thanks to both of you, it worked like a charm

But i thinkin about rewriting the script...

So instead of a 0/1 script ill make it able to fetch any value...

Maybe later

I made a test script to show what i was planning the script to do from the start:

expandcollapse popup

#include <WarUdf.au3>
#include <GUIConstantsEx.au3>

;Write and read UDF variables
$War_Dir = @ScriptDir
$War_File = "test.ini"
$War_Section = "test section"
$War_Key = "test"

;Write and read UDF
$WarUdf = WarUdf($War_Dir, $War_File, $War_Section, $War_Key)

;GUI variables
$EditHeight = 40
$EditWidht = 200
$EdgeRemove = 30
$title = "Info"

;Gui set up
GUICreate($title , 300, 200, -1, -1)
$guihandle = WinGetHandle($title)
$Name = GUICtrlCreateInput("Name", 50, $EditHeight-$EdgeRemove, $EditWidht, $EditHeight)
$Age = GUICtrlCreateInput("Age", 50, $EditHeight * 2-$EdgeRemove, $EditWidht, $EditHeight)
$Occupation = GUICtrlCreateInput("Occupation", 50, $EditHeight * 3-$EdgeRemove, $EditWidht, $EditHeight)
$OkButton = GUICtrlCreateButton("Ok", 50, $EditHeight * 4-$EdgeRemove,$EditWidht, $EditHeight)

;Shows gui if its first time
If $WarUdf = 0 Then
GUISetState(@SW_SHOW)
EndIf


;While loop
While 1
    If $WarUdf = 0 Then;If its first time
        $msg = GUIGetMsg()
        If $msg = $GUI_EVENT_CLOSE then;If close then exit
            Exit
        EndIf
        If $msg = $OkButton Then;If okay then save variables
            GUISetState(@SW_HIDE);Hide gui
            FileChangeDir($War_Dir);Change dir to the ini file
                If GUICtrlRead($Name) = "Name" Then;If the name isnt changed alert user and reset UDF variable
                    MsgBox(0,"Name", "You did not enter your name!")
                    IniWrite($War_File, $War_Section, $War_Key, 0);Reset UDF variable
                Else
                    IniWrite($War_File, $War_Section, "Name", GUICtrlRead($Name));If name is changed then save variable
                EndIf

                If GUICtrlRead($Age) = "Age" Then;If the age isnt changed alert user and reset UDF variable
                    MsgBox(0,"Age", "You did not enter your age!")
                    IniWrite($War_File, $War_Section, $War_Key, 0);Reset UDF variable
                Else
                    IniWrite($War_File, $War_Section, "Age", GUICtrlRead($Age));If Age is changed then save variable
                EndIf

                If GUICtrlRead($Occupation) = "Occupation" Then;If the occupation isnt changed alert user and reset UDF variable
                MsgBox(0,"Occupation", "You did not enter your occupation!")
                IniWrite($War_File, $War_Section, $War_Key, 0);Reset UDF variable
                Else
                IniWrite($War_File, $War_Section, "Occupation", GUICtrlRead($Occupation));If occupation is changed then save variable
                EndIf
            Exit
        EndIf
    Else
        FileChangeDir($War_Dir);Change dir to the ini file
        $Read_Name = IniRead($War_File, $War_Section, "Name", "Not found!");Reads name variable
        $Read_Age = IniRead($War_File, $War_Section, "Age", "Not found!");Reads age variable
        $Read_Occupation = IniRead($War_File, $War_Section, "Occupation", "Not found!");Reads occupation variable
        MsgBox(0,"Name", "Name: " & $Read_Name);Presents name
        MsgBox(0,"Age", "Age: " & $Read_Age);Presents age
        MsgBox(0,"Occupation", "Occupation: " & $Read_Occupation);Presents occupation
        Exit
    EndIf
WEnd

Im not sure, but i think i uploaded the wrong file last time... but im not sure.

This works and is final version:

WarUdf.au3

And then i want to end with saying this forum is great!

Ive asked and you have responded with helpfull tips and pointed me to a syntax i could look up in the helpfile!

Thanks for everything and i will definantly be spending more time here

[BrewManNH]

If you changed the contents of the variable that holds the ini filename to this: $War_File = @ScriptDir & "\test.ini" you could avoid all of the FileChangeDir commands and just access the ini file the same way with the same command. Either way will work, but there's less coding doing it this way.
