Visual Basic 2010 Imagine an application that has a list of items available on the left. These are just variables (ints, objects, doubles, any of the usual programming elements). This list is produced at run time based on the actual programmatic items available.
In the rest of the form there is a multi-line text field for the user to enter visual basic code. The code has access to all the elements on the left. Since all the elements on the left are already declared, something like this would be possible: (the "|" character is to divide the list from the code area) _____________________________________________ x | x = 3 y | y = x + otherVar otherVar | soneClass.someVar = y someClass | ___________|__________________________________ So the list is on the left, and the code the user entered is on the right. I've seen this done with a Java base and BeanShell, but I am using Visual Basic. I know this example above is simple, but you get the idea. I could use an expandable treeview on the left, for example, to illuminate the elements of classes, tooltips for variable types, etc. I've looked at Dynamic Code, and beside being overkill it is not a VB solution. Am I thinking of something that isn't possible? Of course not. But I notice a few things in reading how app domains load assemblies at run time that make my app queezy... App domains don't, as far as I can tell, unload gathered assemblies. Compiling and loading assemblies- even if they are the same name as any previous, will result in an incremental increase in memory used. The whole reason I need a dynamic compile is that the app is a 24/7 app that cannot be taken down to reload, nor give my users the source code and ask that they recompile. So most of the code never changes, but the user can change the business logic any time they want-but without a reboot, restart, or memory problem. TIA! pat :)
