Hi Mike,

If I just added a new line to a vector layer using GM_AddLineToVectorLayer(), is there a way to get the FeatureIndex or LineIndex so that I know which feature is new?

Thanks,

Qiao

    Qiao,

    To get the index of the new feature, simply call GM_GetLayerInfo before adding the feature and observe the mNumLines value. This will be the index of the next line feature added.

    Let me know if I can be of further assistance.

    Thanks,
