GH python error Oasys GSA API: Could not convert argument 1 for call

Hi everybody,

I am starting to work with grasshopper python component to send information to analysis software and to get back results.

The sending and analysing works well. The problems come when I try to get the output. In this case the output needs to be set before requesting for it. I am doing it with this call:

ret = gsaobj.Output_Init_Arr(1,"Global","A1",14003001,3)

In API help the call is documented like this:

short Output_Init_Arr (long iFlags, string sAxis, string sCase, enum ResHeader header, long num1dpos)

so this call has 5 arguments (long, string, string, long, long) (the enums are defined as longs)

This call works, because when I print the ret, i get 0 that is "succeded" so everything works so far.

Then I request the output with the following:

results = [] 

ret = gsaobj.Output_Extract_Arr(10,results,numcomponents)

In API help the call is documented like this:

short Output_Extract_Arr(long iRef, SAFEARRAY(struct GsaResults)*arrayResults, long* numComponents)

I am getting the error "

Runtime error (ArgumentException): Could not convert argument 1 for call to Output_Extract_Arr."

So it seems that is not accepting 10 as a long in the beginning (assuming that argument 1 is the first). I already tried passing a variable as long, using long(10) there, nothing works.

Furthermore I don't know if the other two variables are correct like that. I come from VBA where I need to declare everything but AFAIK python is more permissive in this sense. "results" should be a dynamic array of objects and "numcomponents" a long.

Any help would be appreciated! 

Thanks! :)
