Structure verification through API

Anonymous — Fri, 16 Mar 2012 12:38:19 GMT

I'm writing a script that removes unitilised bars and i need to check for instability after removal of each bar.

Is there any method in the API that checks the model for singularities without running a full calculation?

No, you have to run calculation.

OK.

Is there anyway I can abort the calculations when presented with a warning? I realise that i can abot manually by clicking the dialog box that appers with the warning, but I'm looking for a way to automise this task.

Hope you can help.

Very simple example written in C# which shows how to handle the warnings generated by calculation engine and how to break the calculations if needed.

namespace MyCalc
{
    class Program
    {
        static void Main(string[] args) {
            RobotOM.RobotApplication app = new RobotOM.RobotApplication();
            app.Project.Open(@"c:\Temp\Pdelta.rtd");
            app.Project.CalcEngine.CalcNotifyEx += new RobotOM._IRobotCalcEngineEvents_CalcNotifyExEventHandler(CalcEngine_CalcNotifyEx);
            Console.WriteLine(app.Project.CalcEngine.Calculate().ToString());
            app.Project.CalcEngine.CalcNotifyEx -= new RobotOM._IRobotCalcEngineEvents_CalcNotifyExEventHandler(CalcEngine_CalcNotifyEx);
        }

        static void CalcEngine_CalcNotifyEx(int nCaller, string strText, string strFullText, string strCaption, int nType, int nDataType, string strSelection, out bool bHandled, out int nReturnValue) {
            bHandled = false;
            nReturnValue = 0;
            if (nCaller == 1) { // CALCULATIONS==1
                if (!string.IsNullOrEmpty(strText)) {
                    bHandled = true;
                    nReturnValue = 7; // IDNO=7, break calculations
                    Console.WriteLine(strText);
                }
            }
        }
    }
}
