Hello to anyone who can help me.

I have an (old) roborealm file that I run on images.

Now i would like to start to use the API.

My goal is to have RoboRealm process an image (from file) when available and only do one run/processing on it.

Based on the C# API example I have build:
[code]
// result from some COM object functions
int VARIANT_TRUE = -1;
int VARIANT_FALSE = 0;

RR_COM_APILib.API_Wrapper rr = new API_Wrapper();
rr.SetCOMType(0);

{
    if (rr.Startup() == VARIANT_TRUE)
    {
        rr.Run("off");
        rr.LoadProgram("C:\\run_test.robo");

        //rr.LoadImage("", "C:\\test.jpg");
        rr.LoadImage("", "C:\\test2.bmp");

        rr.Run("once");

        //rr.WaitImage();

        object nameArray = new object();
        object valueArray;
        int num = rr.GetAllVariables(ref nameArray, out valueArray);
        if (num > 0)
        {
            object[] names = (object[])nameArray;
            object[] values = (object[])valueArray;
            int i;
            for (i = 0; i < num; i++)
                Console.WriteLine(names[i] + "=" + values[i]);
        }

        rr.Disconnect();
        rr.Close();
    }
}
[/code]

This runs fine when using test.jpg, GetAllVariables() returns 109 variable objects.
According to RR runtime is 384ms and 10 blobs are found.

It fails though when I input test2.bmp
GetAllVariables() returns 0 objects.
But RR shows (and also debug output is written to files) all the variable objects.
According to RR runtime is 551ms and 282 blobs are found.

Uncommenting "rr.WaitImage();" doesnt change anything.

My gut feeling tells me "rr.Run("once");"is not a blocking operation.
But "rr.WaitImage();" doesnt change the outcome.

Does anybody have an idea why GetAllVariables() doesnt return anything in this case?
If more information is needed please let me know.

Cheers,
Marco
