How to pass data from one Process to another in code .I am using Spring Boot in Java code.
If you use a call activity, then you don't need code to start the referenced process and to pass data. The engine will take care of it if you model the corresponding attributes.
Also see documentation here: https://docs.camunda.io/docs/components/modeler/bpmn/call-activities/

I am currently learning how to start developing on ChainLink, and I saw that there is a GetRoundData() method that is used to return data from a specific timestamp.
When I dig into the code and I found that there the method came from the interface AggregatorV3Interface. Also, I didn't find the implementation of the function inside any of .sol files, but I find it in a .go file.
My question is, how is the aggregator store data on the blockchain? as I see the data come from nowhere when I call getRoundData. If data comes from the module written by Go lang, does that means the data source is off-chain? Thank you.
Code snippet captures:
aggregator_v2v3_interface.go
AggregatorV3Interface.sol
A contract implementing this interface is deployed on an address specified in the _AggregatorV2V3Interface Golang variable.
So your offchain script is connected to a node of some EVM network (Ethereum, BSC, Polygon, ...) and queries the node to perform a read-only, gas-free, call on that specific contract address. The actual data is stored onchain.
I have several (15 or so) builds which all reference the same string of text in their respective build process templates. Every 90 days that text expires and needs to be updated in each of the templates. Is there a way to create a central variable or argument
One solution would be to create an environment variable on your build machine. Then reference the variable in all of your builds. When you needed to update the value you would only have to set it in one place.
How to: Use Environment Variables in a Build
If you have more than one build machine then it could become too much of a maintenance issue.
Another solution would involve using MSBuild response files. You create an .rsp file that holds the property value and the value would be picked up and set from MSBuild via the command line.
You need to place it into somewhere where all your builds can access it, then customize your build process template to read from there (build definitions - as you know - do not have a mechanism to share data between defs).
Some examples would be a file checked into TFS, a file in a known location (file share), web page, web service, etc.
You could even make a custom activity that knew how to read it and output the result as an OutArgument (e.g. Custom activity that read the string from a hardcoded URL).
I have seen some posts that mention the xmlserializer being called at runtime in .Net.
I have a sharepoint web-part that calls a webservice to retrieve data, and then is supposed to display that data on the web-part. But I get this error:
System.Runtime.InteropServices.ExternalException: Cannot execute a program. The command being executed was "C:\Windows\Microsoft.NET\Framework64\v2.0.50727\csc.exe" /noconfig /fullpaths #"C:\Users\my_deploy_spFarm_user\AppData\Local\Temp\OICE_356C17F3-2ED2-423C-8BBE-CA5C05740FD7.0\eelwfhnn.cmdline
Now the posts I have read here, state that the problem is that the compiler is trying to to create an XML serialization assembly on the fly, but does not have privilege to do so.
I have seen some suggestions to use the post-build events to create this XML Serialization Assembly at Compile-time. However I am not sure of how to do that, and also I am not sure if this assemply would get included in the .wsp package?
I'd take a good look at whether you really want the full, automatically generated serializer, or whether you just want to emit/parse some relatively straightforward XML - if the latter, you'll solve this problem by not using stuff that needs generated code, i.e. use the XmlReader/XmlWriter directly.
This link has the basic command to create the pre-compiled serializers.
How can I get a list of all the AT scheduled tasks' application names?
But I want to know how to do it exactly by using function NetScheduleJobGetInfo and AT_INFO Structure?
I'm programming in C++
Actually, I think you have the wrong function. You should be looking at NetScheduleJobEnum() which will give you an array of AT_ENUM structs, one for each job. Inside AT_ENUM is the command associated with the task.
I'm writing a desktop application that communicates with a web service. Would you name all web-service functions that that fetch data LoadXXXX, since they take a while to execute. Or would you use GetXXXX, for instance when getting just a single object.
Use MyObject.GetXXXX() when the method returns XXXX.
Use MyObject.LoadXXXX() when XXXX will be loaded into MyObject, in other words, when MyObject keeps control of XXXX.
The same applies to webservices, I guess.
I would use Load if you expect it to take "file-time" and Get if you expect it to take "simple DB" time.
That is, if the call is expensive, use "Load".
Get. And then provide a way of calling them asynchronously to emphasize that they may be out to lunch for a while...
Do what the verb implies. GetXXX implies that something is being returned to the caller, while LoadXXX doesn't necessarily return something as it may be just loading something into memory.
For an API, use GetXXX to be clear to the caller that something will be returned.
Always use Get, except perhaps when actually loading something (eg, loading a file into memory).
When I read LoadXXX, I'm already thinking that the data comes from some storage media. Since the web service is up in the cloud, GetXXX feels more natural.
