ISGetCurrentWindow is retrieving null

Hi Hamdy,

Thank you for the sample.

Since you are going to close the window from an IFrame button, it is recommended to access the window parent first. Therefore, you could use the following code to modified the code in PageDialogBox sample:

function Button2_onclick() {            
            var wnd = window.parent.ISGetObject("WebDesktopManager1");
            var activeWnd = wnd.GetActiveWindow();            
            alert(activeWnd.Name + " is closed");
            activeWnd.Close();
        }

I hope this could helps.

Regards,

Julia

ISGetCurrentWindow is retrieving null

The issue :

that the windows cllection will remove the child window if the user close a dialog from this child window

So Active window is null and also if I tried to get the window by GetWindow function it will retrive null as well

Then I checked the windows.lenght if gound it zero

I implement a workaroud as follow

 function Button1_onclick() {
            var dialogbox = ISGetObject("WebDialogBox1");
            var wnd = ISGetDesktopManager();
            if (lastwnd == null)
                lastwnd = wnd.GetActiveWindow();
            dialogbox.ShowDialog();
        }

assiging a bublic variable lastwnd before opening the dialog

and in closing

var lastwnd =null ;
 function Button2_onclick() {
            var wnd = ISGetDesktopManager();
    if (wnd.GetActiveWindow() !=null)
        wnd.GetActiveWindow().Close();
    if (lastwnd !=null)
        lastwnd.Close();
        }

I will close this public variable if the GetActiveWindow retrieve null

and It works correctly

Dear Julia

Still the sample not my case

my case , that the button which close the opened window in the window it self not in the parent

I attached your sample after making my case

and it has the error

1- open the dialog box from the child window

2- close the dialog

3- close the child window from the button on it (Close the form)

if i did not open the dilaog box the button will wiork and close the window

sorry the code by VB.net

and also he is the code PageDialogBox

I have follow your step in this sample and its working fine in my end. Could you please try this sample in your place and let me know if this sample work or not?

Below is the following step:

- click on button open 'DialogBox'

- close the dialog box ( click close (x) )

- click on button 'close all' to close the window

If this sample is not work, could you send me your sample project that replicating your issue?

And for better result, please do not forget to use the latest bins before you run the project.

Hi Hamdy,

I'm apologize if I have misinterpret the scenario that you describe in the statement above. If I'm not wrong, are you trying to close the WebDesktop's window and WebMenuBar after open WebDialogBox?

If yes, you could use these snippet :

function Button1_onclick() {
            var wnd = ISGetDesktopManager("WebDesktopManager1");
            var mnuBar = ISGetObject("WebMenuBar1");
            var activeWnd = wnd.GetActiveWindow();
            mnuBar.Hide();
            activeWnd.Close();    
        }

Unfortunately, I'm sorry that I'm not use your code because the codes doesn't work in my end.

Here I attach the sample for you. Please let me know if this sample has appropriate with your need or not.

And if this sample is not fit with your scenario, please let me know the scenario with more details. Thank you.

Regards,

Julia

I have a desktop wep

I want to close an page

so like the sample I am using this code var curWin = ISGetCurrentWindow();

                        ISGetObject("WebMenuBar1").HideAll(); // ensure all menus are closed before exit
                        curWin.Close(true); // close with raise event

but in one page I have a dialog box

if I open this dialog and close it ISGetCurrentWindow function will retrive null and the closing code will not work

I tried to use this fucntion ISCloseCurrentWindow();

also not working

this happenes only if I open the dialog box and close it
