In C, it’s common to define macros that do some stuff getting the verbatim argument, and at the same time define functions to be able to get the address of it transparently. // could evaluate at compile time if __builtin_sin gets // special treatment by the compiler #define sin(x) __builtin_sin(x) // parentheses avoid substitution by … Read more
Using C# (.net 4.0) with SQLite, the SQLiteConnection class has a property LastInsertRowId that equals the Primary Integer Key of the most recently inserted (or updated) element. The rowID is returned if the table doesn’t have a primary integer key (in this case the rowID is column is automatically created). See https://www.sqlite.org/c3ref/last_insert_rowid.html for more.

If you want a simple design, essentially I would do it in a static mapper class. We definitely need more information to help you, but short of that, here is some psuedocode (not production code) that should be a sufficient design pattern. public static class CustomMapper { public static void leadToContact(Lead lead, ID contactID) { … Read more
For use in Visual Studio, this has been answered here. In particular, the string provided in OBWANDO’s answer can be used to set the break point condition. Note, however, that it is a bit klugy. You will receive a warning message when the breakpoint is hit even though the debugger has stopped. It doesn’t appear … Read more
