Need some help!

[darzanmihai]

What would be the reason for witch I cannot create a graphic with GUICtrlCreateGraphic after deleleing it, but in certain conditions:

I have a Gui in witch I have 2 buttons:

- one button is for refreshing the Graphic

- the other button is for opening a child gui

For refreshing the Graphic I am deleting it and then creating it again GUICtrlCreateGraphic .

Everithing is fine until I open the child gui by pressing the button. After closing the child gui, when I refresh the Graphic, it delets it but it wont create it again and the function GUICtrlCreateGraphic returns 0.

I have no ideea what is the reason for this.

Thank you!

Could you post your script? Maybe one of us can find a flaw in your coding and it would certainly make things easier.

The button $GenerareGrafice deletes the graphic control and creates it again. It works fine until I press $AlegeCumparatori or $AlegeFurnizori. After pressing one of those 2 buttons, when I press $GenerareGrafice the graphic will only be deleted but not created again: GUICtrlCreateGraphic() returns 0

Thanks in advance!

You don't have to take this "literally" - you have to prepare a small verion of your script (an example) to show your problem. I doubt some1 will have enough time and patience to look through 1000+ line of code searching for error.

Take this as a friendly advice. You should do accordingly if you want some1 to give you any help.

Also, try some debugging first: use some messageboxes, error codes check to see where your problem is; the best help will come from yourself.

EDIT: a working example must be provided if you choose to post your original script; your code is incomplete, all #Include are missing.

EDIT2 : "inaltimea" is more apropriate than "grosimea" (that's how you translate "height") (just kidding a little bit )

I know what you are saying, and I prepared a small version of the code, but everithing worked just fine...that is why I posted the code you have seen!

I have tried debugging, but the only thing I have found is that the GuiCtrlCreateGraphic() returns 0.....no error no nothing!

Well, after some time spend building this example I've noticed a particular behaviour of GUICtrlCreateGraphic

Example:

expandcollapse popup

#include <GUIConstantsEx.au3>

GUICreate("1", 200, 200, 100)
$but2 = GUICtrlCreateButton("Create Gr Success", 20, 170, 160, 25)
GUISetState()
GUICreate ("2", 200, 200, 310)
GUISetState()
$but = GUICtrlCreateButton("Create Gr Fail", 20, 170, 160, 25)
$gg = GUICreate ("3", 200, 200, 520)
GUISetState()

Do
    $msg = GUIGetMsg()

    If $msg = $but Then
        GUIDelete($gg)
        
        $a = GUICtrlCreateGraphic(20, 50, 100, 100)
        GUICtrlSetBkColor(-1, 0xffffff)
        GUICtrlSetColor(-1, 0)

        GUICtrlSetGraphic(-1, $GUI_GR_COLOR, 0xff0000, 0xff0000)
        GUICtrlSetGraphic(-1, $GUI_GR_PIE, 50, 50, 40, 30, 270)

        GUICtrlSetState(-1, $GUI_SHOW)
        MsgBox(0, "return", "a = "&$a, 2)
    EndIf
    If $msg = $but2 Then
        $b = GUICtrlCreateGraphic(20, 50, 100, 100)
        GUICtrlSetBkColor(-1, 0xffffff)
        GUICtrlSetColor(-1, 0)

        GUICtrlSetGraphic(-1, $GUI_GR_COLOR, 0xff0000, 0xff0000)
        GUICtrlSetGraphic(-1, $GUI_GR_PIE, 50, 50, 40, 30, 270)

        GUICtrlSetState(-1, $GUI_SHOW)
        MsgBox(0, "return", "b = "&$b, 2)
    EndIf
Until $msg = $GUI_EVENT_CLOSE

Particular behaviour: GUICtrlCreateGraphic will try to create the graphic always on the last form created if the last form was deleted then GUICtrlCreateGraphic will fail.

My friend - I think that was what happened to you - you have created a new gui and deleted it and your function was trying to write on that GUI.

I have no idea if this behaviour is intended for this function. What you have to do is to give up creating and deleting graphics and try to clear the current graphic and draw the new one OVER. I know it's "messy" but ... I can't see what else can you do.

I also thought that this wos the problem.....I shall see what I can do

Thanks!

I'll try to open a ticket for this - I'm not sure if it is intended behaviour or a bug.

I don't see that this is a bug. When you create a control the control is created on the last gui referred to. If you have more than one gui, or want the control on a particular gui then you should use GuiSwitch.

Do
    $msg = GUIGetMsg()

    If $msg = $but Then
        GUIDelete($gg)
       guiswitch($g1)
        $a = GUICtrlCreateGraphic(20, 50, 100, 100)

That's brilliant martin

I've never used GUISwitch before ... well what a better example that we always have something to learn

Thanks,

It is brilliant....it is so simple...Thank you!
