Foreach loop, determine which is the last iteration of the loop
...plicate items. In this cases something like this may be more appropriate:
int totalCount = result.Count();
for (int count = 0; count < totalCount; count++)
{
Item result = Model.Results[count];
// do something with each item
if ((count + 1) == totalCount)
{
// do somethi...
Can I use a binary literal in C or C++?
...rams as well (it is 100% preprocessor-driven.)
To do the converse (i.e. print out a number in binary form), you can use the non-portable itoa function, or implement your own.
Unfortunately you cannot do base 2 formatting with STL streams (since setbase will only honour bases 8, 10 and 16), but you...
How do I flush the cin buffer?
...
Possibly:
std::cin.ignore(INT_MAX);
This would read in and ignore everything until EOF. (you can also supply a second argument which is the character to read until (ex: '\n' to ignore a single line).
Also: You probably want to do a: std::cin.clear(...
Visual studio long compilation when replacing int with double
... can easily believe this.
The difference between IEEE standard floating point ops and the ones implemented by a processor often forces linking in library routines to do the translation, while integer math can just use the CPU instructions. At the time the IEEE defined the standard, they made some c...
Ensuring json keys are lowercase in .NET
... a custom contract resolver for this. The following contract resolver will convert all keys to lowercase:
public class LowercaseContractResolver : DefaultContractResolver

protected override string ResolvePropertyName(string propertyName)

HorizontalScrollView within ScrollView Touch Handling
...
Update: I figured this out. On my ScrollView, I needed to override the onInterceptTouchEvent method to only intercept the touch event if the Y motion is > the X motion. It seems like the default behavior of a ScrollView is to intercept the touch event whenever there is ANY Y motion. So with the...
Why isn't vector a STL container?
... &x = b[5]; // that's what really happens
bool y = b[5]; // implicitly converted to bool
assert(b[5] == false); // converted to bool
assert(b[6] == b[7]); // bool operator==(const reference &, const reference &);
b[5] = true; // assignment on reference
assert(b[5] == true); // and actua...
Django Rest Framework File Upload
... very helpful thank you a lot. But i don't understand, why you are converting dict data to QueryDict in parser? In my case in Django, normal dictionary data work perfectly without converting.
