Browser variable between two projects

variable

#1

Is it possible to send browser properties via argument. My loop fails to recognize the browser property mentioned in navigation activity.

Also, how can I check if I have value in browser variable?

Thanks for help in advance

Hi,

you can send browser variable in an argument in the same way as any other variable.

You can check if it’s empty with for example (if myBrowser IsNot Nothing). This returns true if myBrowser has value.

Hi MGDL,
A quick question whether the solution proposed by Topi worked fine with you? I am trying to do a similar thing and keep getting error message whenever I try to get UiBrowser Output variable assigned to the Argument of UiPath.Core.Browser type.

Hi Pawel,

What error are you receiving?

Browser objects are not serializable, meaning they can’t be passed as arguments between workflows that are invoked via LaunchWorkflowInteractive or InvokeWorkflow with Isolated = True.

You could pass the selector and reattach at the other end of the invoke, if you need to use one of those.

Thanks for showing me the right direction.
