Cvb.py set node

Hello
right now I can read nodes from a camera with the following code:

device_node_map=device.node_maps[“Device”]
print (str(device_node_map[“ExposureTime”]

I wonder how I can set a value?

Does anybody has an advice? Thanks a lot

This should do the trick:

device_node_map = device.node_maps['Device']
exposure_time = device_node_map['ExposureTime']
exposure_time.value = 20000.0

Or even shorter for feature nodes:

device_nodes = device.node_maps['Device']
device_nodes.ExposureTime.value = 20000.0

Hi everyone

When trying:

device_node_map = device.node_maps[‘Device’]
exposure_time = device_node_map[‘ExposureTime’]

I get:

Process finished with exit code -1073740791 (0xC0000409)

Working on windows 10 64bit
CVBpy version: CVBpy-v0.9.0.build-265.rev-2949+ Release vc14 @ x64 & CVB+±v1.0.0.build-222.rev-2963+ & CVB-v13.00.006

I can load the camera device and read images in.

Any sugestions?

Thank you,
