dynamic

问题 How do I create a dynamic COM/OLE/ActiveX object in C# 4.0 from a program identifier or ProgID (such as "Word.Application") without referencing a library? In C# 3.5 I'd have to write something like Type comObjectType = Type.GetTypeFromProgID(progId, true); Activator.CreateInstance(comObjectType); Is there an easier way to do it in C# 4.0 so I can assign it to a variable of type dynamic (using the dynamic keyword)? 回答1: What's wrong with dynamic myTypeInstance = Activator.CreateInstance(Type

问题 i have a card game in C (i have to make it in C, class project). And i created a method for moving Structs from one dynamic array to another. Unfortunately the method works at first, but later when i call it in the program it starts throwing malloc() errors.

问题 I have a dynamically-created control which I gave the ID "ckbxEmp" As I discovered by "Viewing Source," Sharepoint (or Chrome, or "somebody") impertinently and presumptuously re-Ids (and names it, and "for"s it) this control, giving it the Welsh-esque "ctl00_ctl24_g_1caf4ad1_092d_4224_bd10_28ab028aab50_ctl00_ckbxEmp" And so (I assume this is the reason), all attempts to manipulate "ckbxEmp" via jQuery fail - that is to say, when I look for the short ID I gave it, like so: $(document).on(
