loops - Vb.Net Wait for Async Response -


i working on windows form application controls number of stepper motors in turn drive camera. stepper motors controlled through arduino acting serial port.

in app, arduino receives absolute position commands (e.g. x;23,y;90,z;120) , moves various motors respective commands, whilst motors moving arduino outputs current position, @ end have output x;ok,y;ok,z;ok response.

as motor positions received arduino, these updated within application on status view, within code need loop below (pseudocode);

for = lowerlimit upperlimit step intervalstep      com1.writeline("x;" & x ",y;" & y & ",z;" & i)      'wait ok response serial port      'capture image next

how go pausing loop (thread) until receive ok response serial port?

many thanks!

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
