Simconnect with vb6

[Glote]

Hi Russel, I'm a french user of MSFS2020. I have nicely developt an API using VB6 and simconnect to access all the simvars and so on (Working Title, Mobifligh.wasm) and all is working well EXCEPT an ugly latency produced by the used time of the sim. So, I've seen you know well VB6 and the sample I read use SimConnect_RequestDataOnSimObjectType instead of SimConnect_RequestDataOnSimObject by using Simconnect_GetNextDispatch instead of Simconnect_CallDispatch which appear to be more efficients. But I don't know to program in the right way (CallDispatch)...
Have you an idea to enlight my mind ?

Thank's in advanced and have a nice day
