I've got a control to draw lines:

new OpenLayers.Control.DrawFeature(vecLayer, OpenLayers.Handler.Path, {
            callbacks : {
            //    "done" : doneHandler,
                "point" : function(aPoint){

and now i can get all points from linestring i add to the map. But what i need is to get length of the feature that is not finished (the reason i can't use done callback).

How can i make this? I'm completly stuck, any help!

Thanks to Aragon, i've made it this way:

        var measure_ctrl = new OpenLayers.Control.Measure(OpenLayers.Handler.Path, {
        persist : true,
        immediate : true,
        handlerOptions : {
            layer : vecLayer
        "measure" : handleFinalMeasurements,
        "measurepartial" : handleMeasurements

and then getting event.measure
