Dynamic variables

Recommended Posts

Depending on the current resolution of the user I would like to define a variable

I came up with this, but this does not seem to work.

The variable only gives me a value of 1 (consolewrite $dheight) for example.

I think the problem lies with eval(). I can only put strings (or text?), but not numbers (like @desktopheight - 200)

Is there another solution to this problem?

 

 

#include <GUIConstantsEx.au3>
#include <MsgBoxConstants.au3>
#include <StaticConstants.au3>
#include <ColorConstantS.au3>
#include <EditConstants.au3>
#include <WindowsConstants.au3>

GLOBAL $x = @DesktopWidth

Switch @DesktopWidth
    Case "1920"
        consolewrite("case werkt 1920")
        ;assign("dwidth",1920 / 2 - 960,2)
        assign("dwidth",$x,2)
        assign("dwidth1",1220,2)
        assign("dwidth2",200,2)
        assign("dwidth3",935,2)
        assign("dwidth4",1920 / 4,2)
        assign("picheight",300,2)
        assign("Picwidth",1820,2)
        assign("Picstartleft",1920 / 2 - 1820 / 2,2)

EndSwitch

Switch @DesktopHeight
    Case "1080"
        assign("dheight",1080 - 430,2)
        ;ConsoleWrite('1080' & @CR)
    Case "900"
        assign("dheight",1080 - 200,2)
        ;Global $dheight = @DesktopHeight - 200
    Case "768"
        assign("dheight",1080 - 200,2)
        ;Global $dheight = @DesktopHeight - 200
    Case else
        assign("dheight",1080 - 200,2)
EndSwitch

        Global $dwidth = Eval("dwidth")
        Global $dwidth1 = Eval("dwidth1")
        Global $dwidth2 = Eval("dwidth2")
        Global $dwidth3 = Eval("dwidth3")
        Global $dwidth4 = Eval("dwidth4")
        GLOBAL $picheight = Eval("picheight")
        GLOBAL $Picwidth = Eval("Picwidth")
        GLOBAL $Picstartleft = Eval("Picstartleft")

        Global $dheight = Eval("dheight")
        If Not IsDeclared("dwidth") Then
        MsgBox($MB_SYSTEMMODAL, "", "The variable dwidth is not declared.")
        endif

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>

Example()

Func Example()
    Local $sFilePath = "..\GUI\logo_autoit_210x72.gif"

    ; Create a GUI with various controls.
    Local $hGUI = GUICreate("Example", 1080, 1920)
    GUICtrlCreatePic("..\GUI\msoobe.jpg", 0, 0, 400, 100)
    consolewrite ($dheight)
    ; Display the GUI.
    GUISetState(@SW_SHOW, $hGUI)

    Local $hChild = GUICreate("", 210, 72, 20, 15, $WS_POPUP, BitOR($WS_EX_LAYERED, $WS_EX_MDICHILD), $hGUI)

    ; Create a picture control with a transparent image.
    GUICtrlCreatePic($sFilePath, 0, 0, 210, 72)

    ; Display the child GUI.
    GUISetState(@SW_SHOW)

    ; Loop until the user exits.
    While 1
        Switch GUIGetMsg()
            Case $GUI_EVENT_CLOSE
                ExitLoop

        EndSwitch
    WEnd

    ; Delete the previous GUIs and all controls.
    GUIDelete($hGUI)
    GUIDelete($hChild)
EndFunc   ;==>Example

 

 

My previous code I did it like this (code below). But then I run into other problems.

 

If @DesktopWidth = 1920 Then
    Global $dwidth = @DesktopWidth / 2 - 960

Don't believe you can re-declare variables with the same name for example try $DTWidth = Eval("dwidth") or just use Eval("dwidth") by itself.

Why use Assign at all? With the code you posted there's absolutely no reason to go that route. Just use something like this:

Global $x = @DesktopWidth, $dwidth, $dwidth2, $dwidth3, $dwidth4, $picheight, $Picwidth, $Picstartleft

Switch @DesktopWidth
     Case "1920"
          ConsoleWrite("case werkt 1920")
          ;assign("dwidth",1920 / 2 - 960,2)
          $dwidth = $x
          $dwidth1 = 1220
          $dwidth2 = 200
          $dwidth3 = 935
          $dwidth4 = 1920 / 4
          $picheight = 300
          $Picwidth = 1820
          $Picstartleft = 1920 / 2 - 1820 / 2

You don't need to use Assign, all of your variables aren't "dynamic" they're just regular variables with "dynamic" values assigned to them. The variables themselves aren't changing name based on something, just the values assigned to them.


If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

Thank you, I will try this out.

Still have a question.. I just don't understand the first line.

Global $x = @DesktopWidth, $dwidth, $dwidth2, $dwidth3, $dwidth4, $picheight, $Picwidth, $Picstartleft

I dont understand how this line works....Why does it needs to starts with $x =

He is defining a number of variables in one line. $x is a variable that holds the @DesktopWidth as its value. The other variables are empty at the moment.
