Hi guys, Im new to writing macros in Xcode and am having a problem writing my own NSLog replacement. I've been using a few examples but want to tweak them slightly, so they act more like Log4. Im trying to write a 2nd macro (or ideally just a delegate of the first) which takes a log level variable as well as the string and arguments fo...
I've created a lot of forms in Excel, which sum, calculate, highlight, index, etc. I can lock or unlock certain parts of it so that users can only edit the input fields, but it's nearly impossible to format Excel to anything other than a straight up grid. I have different inputs needed, in groups of different sizes, and formatting a spre...

I've defined 2 macros: #define HCL_CLASS(TYPE) typedef struct TYPE { \ HCLUInt rc; \ void (*dealloc)(TYPE*); #define HCL_CLASS_END(TYPE) } TYPE; \ TYPE * TYPE##Alloc() { TYPE *ptr = (TYPE *)malloc(sizeof(TYPE)); if (ptr != NULL) ptr->rc = 1; return ptr; } The purpose of these macros...
I was going over the C++ FAQ Lite online. I was browsing inlines again since I haven't found a use for them and wanted to know how the stopped the circular dependency as showed in this answer. I first tried to do the, "Why inlines are better than defines." example with the following code: #define unsafe(i) \ ( (i) >= 0 ? (i) : -(i) ...

Hi, I have an Excel 2003 file. In the first sheet, I put a combo box. After that, I assign a macro to handle the change event. The macro is located a module in the VB Editor's Project Explorer box. In the macro, I want to write some lines to get the index of the combo box's selected item index. What should I write? I wrote the line I...
I've written a macro in Objective-C to perform a safe cast. Here's what it looks like so far: #define SAFE_CAST(OBJECT, TYPE) ([OBJECT isKindOfClass:[TYPE class]] ? (TYPE *) OBJECT: nil) This works really well, but it'd be nice if there was a way to store OBJECT in a variable so it didn't get called twice. For instance, using the ma...

(Question is related to my previous questions here, here, here, and here). I am maintaining a very old application that was ported years ago from DOS to Windows, but a lot of the old C conventions still carry forward. The one particular convention is a setBit and clrBit macro: #ifndef setBit #define setBit(word, mask) word |= mask #en...
Hi all, I have a code that runs on an embedded system and it has to run really fast. I know C and macros, and this particular project is coded mostly in C but it also uses C++ templates [increasingly more]. There is an inline function: inline my_t read_memory(uint32 addr) { #if (CURRENT_STATE & OPTIMIZE_BITMAP) return readOptimiz...

Suppose we have following two classes: class Temp{ public: char a; char b; }; class Final{ private: int a; char b; char c; public: Final(Temp in):b(in.a),c(in.b){} //rest of implementation }; suppose the only use of objects of Temp class is to construct objects of Final class, so I wonder if in current standard of c++...
