A classic source of run problems in C# can be if your using components that are 32bit in an application with the Platform. Setting the Platform Target to x86 will often solve this whilst still allowing the app to run on an x64 platform.

#define

admin — Thu, 16 Dec 2010 13:36:52 +0000

#define is only used to create somthing to test against (e.g. #if DEBUG #endif)

You can’t use it to create macros. Bloody annoying, but get over it – you can’t! So instead use constants. Note that you have to use constants within a class.

Number Defines


const int TIFF_VERSION = 42;

String Defines


const string MY_THINGS_PATH = "c:\\windows\\";
private const string MY_THINGS_PATH = "c:\\windows\\";
