Im programing a LaserProgram for my Lumax card in VB...
And I cant get Lumax_OpenDevice to return anything alse then 0....
If I use the LumaxTest program ONLINE it says that My program are using the card..
But I cant get the Handle Lumax_OpenDevice.
Has Anyone programed Lumax card with VisualBasic?

It seems like Lumax_OpenDevice is failing to return a valid handle. Check if:

The drivers are properly installed.
The card is not already in use by another program.
You are running your VB program with admin privileges.
The correct device index is being passed.
