C Sharp :: ISO 8601 To Standard Date

May 2, 2013

How I can convert an ISO 8601 to a standard DateTime like dd/mm/yyyy.

The string is:
2013-01-03T00:00:00.0000000Z

And I'd want it to show it like so:
03-01-2013

I'm storing this in an SQLite Database and the code I use to store everything:

conn.Open();  
                  command.Connection = conn;
                  command.CommandText = "insert into Test ([Date], [LogName], [Channel], [DateRecord], [SizeInBytes]) values" 
+ "(@Date, @LogName, @Channel, @DateRecord, @SizeInBytes)";  
                                command.Parameters.Add("@Date", DbType.String);
                                command.Parameters.Add("@LogName", DbType.String);
  
[Code] ....

the Visual aspect is that I use a datagridview to see the data, so the conversion would have to happen while I read and store the data in the database.

C :: Date Math Using Standard Libraries?

Dec 22, 2013

Is there any way to do date math using standard C libraries? I looked around in the time.h but didn't see what I needed.

What I need to do is be able to add a certain number of minutes to a date and have it give the current date/time. For example, add 15918765 minutes to 01/01/1980 00:00 and have it tell me 04/07/2010 4:45PM. I really don't want to write this myself or go platform-specific.

Does this exist somewhere or am I SOL?

C Sharp :: Compare Date In Registry With Local Time?

Feb 2, 2013

The first time my application opens up, it should get the local date out of the System and store this in a registry key. But the second time it should get the date stored in that registryKey and compare it to the date right now.And there is where I am stuck, I just don't know how to get the date out of that key and compare it to the date right now.

This is my code:

RegistryKey key1;  
        private void btnTrial_Click(object sender, EventArgs e) {
            DateTime current = DateTime.Now;  
            key1 = Registry.CurrentUser.OpenSubKey("myKey");    
            if (key1 == null)

[code]....

at the last "if" statement it should compare the date stored in the key with the DateTime.Now.

C++ :: How To Make Standard Deck Of Cards

Feb 6, 2014

How to make a standard deck of cards and being able to shuffle and distribute the cards. I have made an array to store each card and I can display them but I assigned them all in order according to the suit and rank. Is this a viable way to do it if I intend to have a shuffle effect? Or should I create an array, randomly generate card, check for duplicates, then put them in the array, then display the array? Each card is a structure with two void pointer members for suit and rank.

C :: Why Not The First Line At The Standard Input Read

Mar 21, 2013

Here's my code, it's for a poker hand evaluator

input:
'ad 2d 3d 4d 5d...
...4s 5s 6s 7s 8s'

I think it should go through all the 10 crads and disply the name of each card, but it seems to only do it for the second hand

Code:
include <stdio.h>
#include <ctype.h>
int main( void ) {
char inputtedhand[64];
int z=0, counter=0;
int index;
int i=0,m=0,n=0;

C :: Calculate Equations Just Like A Standard Calculator

Oct 23, 2013

The main point of the program is to calculate equations just like a standard calculator but I wanted to do it myself. I don't understand what the problem is right now but I've managed to create a program that asks for both values but somehow it doesn't want to ask for an operator (*, /, + etc). What's wrong with my code that the terminal skips the scanning part for the operator?

Code:

int main() {
int value1, value2, answer;

C++ :: Looking For Standard Namespaces Inside Own Files

Sep 2, 2013

This has never happened before but I imagine that I've somehow accidently disabled a library or such.

namespace Data{
class DLL Filed abstract{
//DLL is a macro defined as either __declspec(dllexport) or __declspec(dllimport)
//depending on whether this is open as a project or a header

The error is from intellisense and is present on every occurrence of std::string
