ReadOnlyCollection or IEnumerable for exposing member collections?
...If you're using .NET 3.5, you can avoid making a copy and avoid the simple cast by using a simple call to Skip:
public IEnumerable<Foo> Foos {
get { return foos.Skip(0); }
}
(There are plenty of other options for wrapping trivially - the nice thing about Skip over Select/Where is that t...
Does MS SQL Server's “between” include the range boundaries?
... When using BETWEEN to filter DateTimes between two dates, you can also cast the DateTime to a Date, eg: where CONVERT(DATE, MyDate) BETWEEN '2017-09-01' and '2017-09-30' This approach makes the time element of the DateTime irrelevant

constant pointer vs pointer on a constant value [duplicate]
...is constant and immutable but the pointed data is not.
You could use const_cast(in C++) or c-style cast to cast away the constness in this case as data itself is not constant.
const char * a;
means that the pointed data cannot be written to using the pointer a.
Using a const_cast(C++) or c-style ...
Conversion failed when converting date and/or time from character string while inserting datetime
...re are many formats supported by SQL Server - see the MSDN Books Online on CAST and CONVERT. Most of those formats are dependent on what settings you have - therefore, these settings might work some times - and sometimes not.
The way to solve this is to use the (slightly adapted) ISO-8601 date form...
Enum “Inheritance”
... int values to the constants as defined in the existing enum, then you can cast between the enum and the constants, e.g:
public enum SomeEnum // this is the existing enum (from WSDL)

A = 1,
B = 2,

Random float number generation

This will generate a number from 0.0 to 1.0, inclusive.
float r = static_cast <float> (rand()) / static_cast <float> (RAND_MAX);
This will generate a number from 0.0 to some arbitrary float, X:
float r2 = static_cast <float> (rand()) / (static_cast <float> (RAND_MAX/X));...
