I’m using C# to create LL Designer. My original data source is from multiple XML files (no relationship) but since LL Card doesn’t support multiple XML files. I plan to flatten XML and combine them in a queue. What is the fast way to send the value of this queue as variables to LL Designer or how to create manual variable ? Or if anyone can point me to the sample or manual to read on, it would be great too. I looked into all .NET samples and programmer’s manual but can’t find what I am looking for.
