could not start dss node in visual programming language RRS feed

  • Question

  • hi, i'm a absolute beginner to MSRDS. Tried my first Hello world program in Visual Programming Language.
    I got an error.
    "Could not start DDS node. Please check if there is another DDS node already running on the system."

    Please help me. :/

  • This likely means there is some process using the same port (e.g. 50000). Usually this means, as the error says, that there is another DSS host already running. Maybe run task manager and look for dsshost32.exe. It could also be some some other process using the port. From a DSS command prompt, try running httpreserve to ensure you can access the port you want. Or, switch to using another port (in VPL, that's under Run > Port Settings).

    Hope that helps!
