CWebStudio

ShortCuts

You can also use shortcuts to set the search requirements as the same name of the id/class that you want to find.

    //means some information were not provided or it's with the
    //wrong type
    if(CWebHyDrationBridge_has_errors(bridge)){
        return;
    }
    bool name_its_empty = strcmp(first_result_of_name, "") == 0;

This example demonstrates how to use shortcuts in HyDration.
