1) object_getIvar(id object, Ivar ivar) returns an 'id' if the Ivar is an object eg. if the variabe is an NSString, presumably the id = NSString which contains the value. Is that correct? Or what do I need to do to access the value of the Ivar. 2) if the Ivar is a float/int etc. what will get returned and how do I convert it into someth...
if the variable in object_getIvar is a basic data type (eg. float, int, bool) how do I get the value as the function returns a pointer (id) according to the documentation. I've tried casting to an int, int* but when I try to get that to NSLog, I get error about an incompatible pointer type. ...
If I return nothing explicitly, what does a php function exactly return? function foo() {} What type is it? What value is it? How do I test for it exactly with === ? Did this change from php4 to php5? Is there a difference between function foo() {} and function foo() { return; } (I am not asking how to test it like if (foo() !=0) ....
Hi, this is more of an advise thread I guess. I've been wondering how one could create a button which display "play" when it's not pressed. And then shows "pause" once it's pressed. And visa versa when it's pressed again. I had a similar problem when trying to create an expand panel button, but that was easy because I could just set a ...
Hi, this is very strange. All of a sudden, I get this error message from Visual Studio saying that TypeInitializationException was unhandled. Searching for this error reveals that I should check if a variable is null(nothing) or not. My scenario is like this. I have a separate GlobalVariables.vb module which I create variables in. I do...
In C, automatic variables, if uninitialized, hold a garbage value. However, consider the following program: int main(){ signed char term; (char)term--; printf("%d\n",term); } It prints a value of '7'. If I don't do a (char)term--, it prints a value of '8'. So, it definitely doesn't hold a garbage value. Isn't this contradictory? ...
Now I understand this has been asked to go from Parent to Child before, which is all well and good, but what I want to know is, how do I go about passing from a Child SWF back to the Parent? The way I do it for Parent to Child is: In your parent swf you’d put _global.myvariable = blah; In your child swf you’d put this. myvariable =...

This is a kind of follow-up from my last question if this can help you. I'm defining a few ctype structures class EthercatDatagram(Structure): _fields_ = [("header", EthercatDatagramHeader), ("packet_data_length", c_int), ("packet_data", POINTER(c_ubyte)), ("work_count", c_ushort)] class EthercatPacket(Structu...
I'm just curious... Is it possible to release a variable in c#? What I mean is, can you do something like this: ... string x = "billy bob"; //release variable x somehow string x = "some other string"; //release variable x somehow int x = 329; ... ... so basically you are declaring the variable multiple times in the same scope. ...
I saw a few answers to this issue, and I get it — you can't declare and assign variables inside a switch. But I'm wondering if the following is correct at throwing an "error: expected expression before 'int' switch (i) { case 0: int j = 1; break; } Why would putting an NSLog before it result in no errors? switch ...

In Firefox the following selector works: $flashvars1 = $(".homepagecolumn1 embed").attr("fla...
1) What's the policy for declaring a variable? Should you always use the keyword private, or is it OK to skip it? string MyVar1; vs. private string MyVar1; The only reason I see is that Microsoft one day can change the default access modifiers to public instead of private. Where does it say that private is optional? Any references...
