Get Session Info Operation - Edit IVI Tools Step Dialog Box
Get Session Info Operation
Use the Get Session Info operation to retrieve the low-level session manager instrument session as well as the API class handles and references to the IVI instrument.
Note
Do not pass an instrument handle between operating system processes because instrument driver handles you obtain in one process do not function in any other process.
Get Session Info Operation
The Get Session Info operation contains the following options:
- Session Manager Reference —A variable or property to which the step assigns a COM pointer to the InstrSession object that session manager creates for the specified logical name. You can use an InstrSession object to obtain an instrument API handle or reference.
- Class Driver C Handle —A variable or property to which the step assigns the C-based class driver API handle for the specified logical name. You can use a class handle to control an instrument with an IVI class driver.
- Specific Driver C Handle —A variable or property to which the step assigns the C-based specific driver API handle for the specified logical name. You can use a class handle to control an instrument independent of the IVI class driver.
- ActiveX Control Reference —A variable or property to which the step assigns the COM pointer to the Measurement Studio for Visual Basic ActiveX control for the class the logical name specifies. You can use a control reference to interact with the instrument using the Measurement Studio COM interface.
