Check for open models?

Hi Martin,

The only way I got this to work is to use a macro. You can then call the script from the macro after closing open models...

Hope this helps.

Thanks Francois. Unfortunately Macros can only detect open models on your own client. I need a way to detect models currently opened by other users on the server.

Hi Martin,

Idea is that you try to set a model flag, if it does not allow you to set the flag, the model is open. Catch the error and go from there...

var lng = Context.getSelectedLanguage();

function main() {
    var selMods = ArisData.getSelectedModels();
    for(var mc = 0; mc < selMods.length; mc++) {
        var curSel = selMods[mc];
        try {
            curSel.changeFlag(Constants.MODEL_PRINT_LANDSCAPE, true);
        }
        catch(e) {
            var modOpen = true;
        }
    }
}

main();

You could also possibly use an attribute instead of a flag... Thought there should be a flag, that's why I started there :)

Hope that helps,

Francois

Martin, you can use a hack like this:

var models = ArisData.getSelectedModels();
for( var i = 0; i < models.length; i++ ) {
    var model = models[i];    
    if( !isWriteable( model ) )
        Dialogs.MsgBox( "Model is not writeable: " + model.Name(-1) );
}

function isWriteable( m ) {
    try{
        var bpc = m.getBgColor()
        return m.setBgColor( bpc );
    }catch( e ) {
        return false;    
    }
}

Hello,

You can use this trick : Try to change the background color, if it fails, then this means the model is opened (or locked) :-)

E.g. :

var oldBg = model.getBgcolor

try{

model.setbgcolor(black)

}catch(err){

model is open...

}

Thanks! Neat little hack.

Hello, All!

Info about error ("Unable to save modified objects.") is always written to log file. It doesn't depend on using try-catch block or not.

Hi Martin,

I think there is some confusion. A macro if it is deployed on a server, you will get to execute it on server. Hence, if you write a macro to check if a model is open and deploy that macro on the server it will let you know if a model is open even by some other user. 

Besides, while checking if the model is open using a report, you can use 'lock' and subsequently 'unlock' API on the model. When you do 'lock' to a model and if the model is already open you will get an error in the 'LockResult' and by using the API 'getErrorMessage()' you can check if the model is open or is it locked by some user.

Hope this resolves your query.

Hi,

I tried this piece of code today but seem to get en exception/error every time when trying to change the background colour of a model, regardless of if it is open or closed.

Does anyone have an idea of why the object is seen as read-only even if the model is closed?

Thanks for any input!

Addition: In fact later today I found the reason for this behaviour - the report script did not have the "Writes to database" checkbox selected.
