Hello Forum,

I am building a Visualization Library made out of custom Visualization Elements.

Right now I would like to use the UserManagement functionality within my functions similar to the way it is used in the codesys library.

For example:

How could I call this function from User Management ?

I have seen the post regarding the KeySwitch_VisuClient but I am still not sure how to really implement that. ( I also think it isn't the same thing I want to implement, but highlights a bit how the VisuUserManagement works)

Could someone please provide more info regarding the best practices when using the VisuUserManagement function OpenLoginDialog for example.

I would like to do something like this - For example the xFoo is set when a button is clicked:

pClientData     : POINTER TO VisuElems.VisuStructClientData;
xFoo : BOOL;

IF xFoo = True THEN
    VisuUserManagement.OpenLogInDialog(pClientData := This^.pClientData)
END_IF

Basically I would like to pass the event to openLogInDialog. So far when I do this, I get a dialogbox which gets stuck and I can not manage to get rid of it. Mainly it is because I have yet not understood how the VisuUserManagement functionalities really tick, or maybe I am not handling it the way it is meant to be handled.

I would appreciate any answer to this topic.

Thanks,

KBK

Ok after tinkering a little bit and I understood how this works. This opened other questions.

so basically one has to get all connected clients by doing the following - This was taken from VisuClientIPAdresse_v1.1 Project so I do not take credit for that (but I will comment it):

VisuElems.g_ClientManager.BeginIteration();

// get next client 
pClient := VisuElems.g_ClientManager.GetNextClient();

WHILE pClientData <> 0 DO
    // as long as a client is available do
    IF( pClientData^.GlobalData.ClientType = VisuElems.Visu_ClientType.Targetvisualization )THEN
        pClientDatatTargetVisu := pClientData;  // assign it to a Global variable if its target visu
    ELSIF ( pClientData^.GlobalData.ClientType = VisuElems.Visu_ClientType.Webvisualization )THEN
            pClientDatatWebVisu := pClientData; // assign it to a Global variable if its web visu
    END_IF
// get next client
    pClientData := VisuElems.VisuElemBase.g_ClientManager.GetNextClient();

END_WHILE

What I am trying to do is the following:

1 - I have created a library with a drop down list (which is conform to our own Style)

2 - I use an FB within the library that manages the click events

-> I extend the click event function within my project in order to call the Login Dialog from the UserManagement library. Now here is the tricky part. Usually our display is given out to all the clients. We have a total of 1 Target Visualization and up to 2 Web Visualizations (we limited it for performance reasons).

For the login event we would like however to differentiate between which request came from where. So if someone is on the target visu entering the credentials , the login dialogue doesn't pop up on our web visualization and vice versa.

I added the Library VisuGlobalClientManager in order to use CURRENTCLIENTID. However I checked all the information and all Clients have the Currentclientid = -1.

Am I missing anything ? why are all the currentclientid = -1 ? How can I get some kind of unique Identification based on a click event to know where the click came from, from Target Visu ? or WebVisu ?

I have struggled with this myself. My solution is to broadcast the dialog to all clients then, upon receiving confirmation from the active client, close the dialog on the remaining clients.

Open the dialog on all clients:

METHOD OpenWarningDialog
VAR_INPUT
    DialogName: STRING(128);
END_VAR

VAR
    isDialogOpen: BOOL;

//  visuMgr: VU.IVisualizationClientIteration;
    dlogMgr: VisuElems.IDialogManager;
    clientDataPtr: POINTER TO VisuElems.VisuStructClientData;
    warningDlog: VisuElems.IVisualisationDialog;
END_VAR

dlogMgr:= VisuElems.g_VisuManager.GetDialogManager();
warningDlog:= dlogMgr.GetDialog(DialogName);

VisuElems.g_ClientManager.BeginIteration();
clientDataPtr:= VisuElems.g_ClientManager.GetNextClient();

WHILE clientDataPtr <> 0 DO
    isDialogOpen:= VisuDialogs.VisuDlgUtil_IsDialogOpen(warningDlog, clientDataPtr, dlogMgr);
    IF (NOT isDialogOpen) THEN
        dlogMgr.OpenDialog(dialog:= warningDlog, pClient:= clientDataPtr, bModal:= TRUE, pRect:= 0);
    END_IF
    clientDataPtr := VisuElems.g_ClientManager.GetNextClient();
END_WHILE

Close the dialog on all remaining clients.

METHOD CloseWarningDialog
VAR_INPUT
    DialogName: STRING(128);
END_VAR

VAR
    isDialogOpen: BOOL; 
    //visuMgr: VU.IVisualizationClientIteration;
    dlogMgr: VisuElems.IDialogManager;
    clientDataPtr: POINTER TO VisuElems.VisuStructClientData;
    warningDlog: VisuElems.IVisualisationDialog;
END_VAR

dlogMgr:= VisuElems.g_VisuManager.GetDialogManager();
warningDlog:= dlogMgr.GetDialog(DialogName);

VisuElems.g_ClientManager.BeginIteration();
clientDataPtr:= VisuElems.g_ClientManager.GetNextClient();

WHILE clientDataPtr <> 0 DO
    isDialogOpen:= VisuDialogs.VisuDlgUtil_IsDialogOpen(warningDlog, clientDataPtr, dlogMgr);
    IF (isDialogOpen) THEN
        dlogMgr.CloseDialog(dialog:= warningDlog, pClient:= clientDataPtr);
    END_IF
    clientDataPtr := VisuElems.g_ClientManager.GetNextClient();
END_WHILE

@barton Thanks a lot for your answer. I'm afraid that is a nightmare. There is no way of identifying where the click came from ? either some kind of function which returns the ID ? do you know where the USERCLIENTID comes from and if it is somehow during initialization set? Or is it provided by the OEM ?

Thanks

Have you seen this example?

I'm going to use this to determine if a particular client is currently displaying the visualization that I'm interested in. You could use this if the the event that you are seeking takes place only on a certain visualization. Inside the loop previously posted, find the name of the current visualization:

    currentVisu: VisuElems.VisuElemBase.IVisualisation;
    currentVisuName: STRING;
    fullNameFlag: BOOL:= FALSE;

WHILE clientDataPtr <> 0 DO
    currentVisu:= clientDataPtr^.GlobalData.LastVisu;
    currentVisuName:= currentVisu.GetName(fullNameFlag);
    isDialogOpen:= VisuDialogs.VisuDlgUtil_IsDialogOpen(warningDlog, clientDataPtr, dlogMgr);
    IF (NOT isDialogOpen) THEN
        dlogMgr.OpenDialog(dialog:= warningDlog, pClient:= clientDataPtr, bModal:= TRUE, pRect:= 0);
    END_IF
    clientDataPtr := VisuElems.g_ClientManager.GetNextClient();
END_WHILE

I am sorry but I dont really get what you are trying to do? Why is the input action not good enough? What trigger are you trying to use then? Why do you have to iterate over all clients?
