block err

[mikesch]

I'm using vb6,  When I try to Initialize a block I get a block error. The return -2 (Can't find block). If I run ni dialog first then vb code Initialize the block.   I'm using  ni fuction nifOpenBlock

The nifbstd.dll 4/6/06 and ni-fbus Communications Manger 3.1.1

The sequence of initializing a block is :

open session -> open link -> open device -> open vfd -> open block

Please check your code, whether all the actions have been performed before open block.

NI Dialog also will do these tasks automatically to initialize block.

You can refer to example code:
