I have code like: var t = SomeInstanceOfSomeClass.GetType(); ((t)SomeOtherObjectIWantToCast).someMethodInSomeClass(...); That won't do, the compiler returns an error about the (t) saying Type or namespace expected. How can you do this? I'm sure it's actually really obvious.... ...
You can see what i'm trying to do below: typedef struct image_bounds { int xmin, ymin, xmax, ymax; } image_bounds; #define IMAGE_BOUNDS(X) ((image_bounds *)(X)); typedef struct { image_bounds bounds; float dummy; } demo; int main(void) { demo my_image; /* this works fine */ ((image_bounds *)(&my_image))->xmin...
Hi, In Groovy you can do surprising type conversions using either the as operator or the asType method. Examples include Short s = new Integer(6) as Short List collection = new HashSet().asType(List) I'm surprised that I can convert from an Integer to a Short and from a Set to a List, because there is no "is a" relationship between t...
Everything seems to be a string right now & that kinda ruins the whole xml as an internal data structure thing, I don't need a big tree of string I need typed data :-/ Are there any changes I can make to either my XML files or my AS3 code that will force it to cast ints as ints and Numbers as Numbers? Or maybe some kind of type schema I ...
Is there any difference between type casting & type conversion in c++. ...

I need a way to cast an object to a type that is not know at compiler time. something like this: object obj; public (type of obj) Obj { get { return obj } set { obj = (type of obj)value; } } The only thing that is know is that obj is a value type. I doubt that something like this would be pos...
Hi all, Let us suppose the following table (e.g. a result of several inner join statements): id | column_1 | column_2 ------------------------ 1 | 1 | 2 | 2 | 2 3 | | 3 Which you could for example get from the following statement: select a.id, t1.column_1, t2.column_2 from a left join t1 on a.id = t1.id le...

I currently have an arrayCollection in Flex and I want to sent it to PHP (Zend_AMF). According to the Zend_AMF wiki, sending an arrayCollection over directly will force Zend_AMF to cast the arrayCollection as an object which is no good. I'd rather have an array of my models. I assume the best way would be to convert the arrayCollection...
I have this XML document <AdditionalParameters> <PublishToPdf Type ="System.Boolean">False</PublishToPdf> </AdditionalParameters> in my code and I'm trying to build an array of arguments containing the <PublishToPdf> node. object test = (object) ((typeof(publishNode.Attributes["Type"].value)) publishNode.InnerText); This breaks at ...

Hi, I'm trying to cast from one generic to another, say: myClass<MoreAbstract> anItem = myclass<DerivateFromMoreAbstract> anotherObject; Or do something like aFunction(anotherObject); // myclass<DerivateFromMoreAbstract> anotherObject where aFunction signature is aFunction(myClass<MoreAbstract> item); In fact, myClass is actual...

If i have some code like the following: short myShortA = 54; short myShortB = 12; short myShortC = (short)(myShortA - myShortB); Both operands are shorts and it's going into a short so why do i have to cast it? ...
I'm aware that questions like this have been asked before and I doubt it's possible, but I just wanted to make 100% sure that it isn't. In VB.net or C# (either language, it doesn't matter), I want to cast a variable to a type represented by another Type variable. Here's an example of the kind of code that would be needed in C#: Object...
I am porting some C code to a TI DSP chip environment. I'm grappling with the C compiler. I have a data structure that includes a pointer to a function. I have a function that initializes the data structure. Something like this: typedef void (*PFN_FOO)(int x, int y); struct my_struct { PFN_FOO pfn; }; init_struct(struct my_str...
