C# :: Using DateTime Field From SQL Database

Oct 30, 2014

I have a DateTime field on a database it looks like this :

2014-10-21 14:34:37.697

I want to use it, as is, in an UPDATE statement something like:

UPDATE PayrollRuns SET IsProcessed = 'True' WHERE Date_Time_Triggered = '2014-10-21 14:34:37.697'

I must have the exact date & time as that uniquely identifies the record.

The problem I'm having is getting it off the database and into an C# variable without it being changed.

I can get it into a string but it changes it becomes:

21/10/2014 14:34:37

I've got it in an object. I've tried:

string date_Time_Triggered = databasesRow["Date_Time_Triggered"].ToString();
//
//and
//
var date_Time_Triggered = databasesRow["Date_Time_Triggered"];

C# :: Convert From Datetime To Unix Time?

Sep 1, 2014

I am converting unix timestamp to datetime format like this:

static readonly DateTime UnixEpoch = new DateTime(1970, 1, 1, 0, 0, 0, 0, DateTimeKind.Utc);
static readonly double MaxUnixSeconds = (DateTime.MaxValue - UnixEpoch).TotalSeconds;
public static DateTime UnixTimeStampToDateTime(double unixTimeStamp) {
return unixTimeStamp > MaxUnixSeconds
? UnixEpoch.AddMilliseconds(unixTimeStamp)
: UnixEpoch.AddSeconds(unixTimeStamp);
}

use it:

Console.WriteLine("From UNIX do datetime 1300123800440 : " + UnixTimeStampToDateTime(1300123800440));

output: 14.03.2011 5:30 PM

Now i would like to have function which convert it back to unix timestamp but unfortuently my new function is cutting down last 3 digits for instance:

public static long UnixTimestampFromDateTime(DateTime date) {
long unixTimestamp = date.Ticks - new DateTime(1970, 1, 1).Ticks;
unixTimestamp /= TimeSpan.TicksPerSecond;
return unixTimestamp;
}

after use of it i am retrieving:

Console.WriteLine(UnixTimestampFromDateTime(Convert.ToDateTime("14.03.2011 5:30 PM")));

result:

1300123800

C/C++ :: Retrieve Data From USB Device

Jun 16, 2014

I am looking to retrieve data from a USB device, this device is a fingerprint scanner. Because I bought it online and wasn't reading carefully enough, drivers and other installation programs weren't included. Send it back? Nah . . .

I want to see if it is possible to retrieve data from this device. To be honest, I don't even know if it's possible, but I would love to give it a whack.

I looked into making INF files and things Microsoft has put out, but I honestly don't know where to start simply because I have absolutely no experience doing this. I have a program set up to organize the data and such, I just need to find a way to actually get it.

What should I research and look into? Are drivers necessary?

Here is a little more information :-)

I want to save data from a fingerprint scanner.I bought a fingerprint scanner, but nothing came with it (drivers, software, etc.). I decided to not return it and see what fun I could have.

I have no code written up yet (mainly because I don't know where to start). But I looked into the device a little...Microsoft recognizes it as a "Fingerprint Scanner" but is still considered unrecognized.I have the USB identifier (at work right now, don't have it on hand)...

Is it even possible to communicate with the device without the initial drivers.Do I really need drivers for the device, or can I communicate with it as it is now.If I do need drivers, where should I start?What should I look into to get communicating with the device?

C++ :: Retrieve Data / Files From A Server?

Feb 25, 2013

I was wondering if i had to say simply retrieve data from a server whether it be simple plain text for variables or download whole files (FTP), what would be the best method for this? I would imagine there is a pretty big difference between retrieving text and downloading files but im just wondering what the best thing would be to research for both.

C++ :: Retrieve Object From Hash Table

Feb 25, 2013

I'm trying to retrieve the Player object from my hash table so I can edit the content of that object. Here is what I have.

Player* HashTable::retrieve(char * key, Player& aPlayer) {
//calculate the retrieval position (the index of the array)
size_t index = calculateIndex(key);
//search for the data in the chain (linked list)
node * curr = table[index];
char id[100];

[Code] .....

Here I'm calling the retrieve and I need to return a pointer of that object.

Player* PlayerDB::FetchPlayer(char* name) {
Player* info = new Player();
out << "Fetching player " << """ << name << "" -- ";
if(h.retrieve(name, *info)) {
out << "Success!" << endl;

[Code] .....

And here is my call in main.
Player* outPlayer = NULL;
outPlayer = pdb.FetchPlayer("Sappho");
if (outPlayer != NULL) {
outPlayer->LevelUp();
}

I'm just trying to change the actual level of the player using the LevelUp function, but right now it is not making that change. I've been told I need to return a reference of the object in my retrieve function, but I thought that was what I was doing already.

C/C++ :: Retrieve Index After Bsearch Or Lfind?

Jul 15, 2014

Basically, I'm trying to figure out the index in an array from a pointer that is returned by either bsearch or lfind.

void *val;
void *begin = (char *)v->elems (I need to use this separate variable)

Then, I call on either search, which seems to be working fine...

val = bsearch(key, begin, v->count, v->elemsz, cmp);

I'm trying to do the following:

index = *(int*)((char*)value_to_find - (char*)start_ptr)/sizeof(cv->elemsz)

However it segfaults everytime I do this. My logic is that I cast both void pointers to type of char*, then subtract the distance b/w the pointers since you can't do pointer arithmetic on void. I divide this by the size of each element to return the index, which needs to be cast to an int. What am I missing here?

Visual C++ :: Retrieve IP Information On Any Windows

Sep 23, 2012

I used to retrieve IP and NIC information by querying windows registry. Now I'm trying to use GetAdapterAddresses() API. Using GetAdapterAddresses() to get IP is not that easy, I need to dig a long deep as I check some examples so far, anyways my question is: Calling this API will return success on all versions of Windows ie: 32bits & 64bits ?

Though Microsoft has not opened any source, where this API is actually retrieving Windows IP information.?. Is it reading Registry or some windows file.
