C# :: How To Retrieve Only Date From Datetime From Database
Nov 25, 2014
i have a form in which i have a field date of birth , and a textbox to fill date of birth , when a person fills his date of birth like 01/01/1990 , then it will be saved into database , and when i retrieve this date form database then this comes 01/01/1990 12:00 AM , i want only date part from it.
i have saved my data in sql and i can retrieve them except datetime i can't retrieve ,, this is my code
SqlCommand cmd1 = new SqlCommand("select ID,name,carplatnumber,cartype,expiredate,badgtype from [ID-personal] where id like('" + textBox1.Text + "%')", cn); SqlDataReader dr1;
I wanted to retrieve all rows from database and display in listview using list<string>
con.Open(); MySqlCommand view = new MySqlCommand("Select Cust_ID,Fname,Mname from Customer;", con); MySqlDataReader v1 = view.ExecuteReader(); while (v1.Read()) { for (int i = 0; i < v1.FieldCount; i++){ result.Add(v1["Cust_ID"].ToString());
I am creating an employee details project, the image is getting stored in the database but i am not able display it in the picture box.
private void button1_Click(object sender, EventArgs e) { SqlConnection con = new SqlConnection(Connectionstring); con.Open(); SqlCommand cmd = new SqlCommand("select photo from emprecordtable where eid='"+comboBox1.Text+"'", con); //SqlDataAdapter da = new SqlDataAdapter(cmd); //DataSet ds = new DataSet();
[code] ....
In sql server i have table called emprecordtable and i have the fields eid, rfid, empname, designation, phno, addres, and photo which is the image field and i have given the datatype as image but in the database the image is getting stored as Binary Data.. So, how to display in the picturebox from the database.
i am student working on a project in c# to maintain the datas from a solar battery monitoring.i already imported the datas from the battery monnitoring and saved them in mysql database and retrived the data in c#.
i have problem in retriving the data in accordance with the date and time range selection.
what i am trying to do is there are more than 1000 datas in the table if i select two date and time the datas in the table should cross check these dates and show all the datas in the table in between those date&time
I am not getting all the records.... when i select the same date in both datetimepicker no record is displayed... i also want the record of the selected dates from both datetime picker..
i'm making a program that, given a person's birthdate or any other date, will display the day of the week of the person was born.
There is this part where it says "use a switch statement to make this calculation, If desired month is 12, add the number of days for November, if desired month is 11 add the number of days for october....
So it's suppose to start with "case 12 :...
I can't figure out what to write for the statement....
I have two date/time structures which I'm populating, but when I populate the second one it sets the same values in the first. This is what I've got so far
I'd like to get a a field name "eventDateTime" from a DB table and its storage is datetime year to fraction (3) . I have created a function return results like this but i put its type as a int:
int Status::GetEventFromSQL(){ int j = 0; int eventTime = 0; MYSQL_ROW myROW; MYSQL_RES *myRES = NULL;
[code]....
"eventTime " is also declared in another sheet .h as an int. In execution i have a big and negative number ; I know that's because of the int type but i'm bigenner in C++...
I currently have a DatePicker in my xaml forum. In my constructor and class I have my dates as a DateTime object. I am currently trying to get my datepicker date to be passed into my constructor or maybe I have to convert the datepicker to a datetime object?
private void btnSave_Click(object sender, RoutedEventArgs e) { DateTime xxx = new DateTime(); xxx = Convert.ToDateTime(dateCurrent.SelectedDate); //validate registration form lifter = new User(txtFirstName.Text, txtLastName.Text, txtStartWeight.Text, genderStatus, xxx);
I have an application in C sharp that searches for a record in a sql database using a datetimepicker,the output is displayed in a datagridview.When I execute it I got a blank datagridview with empty columns.I can not view the content and I don't get any error message.
Here is my code:
DataTable dt=new dataTable(); SqlDataAdapter sda=new sqldataadapter("select * from Delivery where convert (char(20),Delivery_Date,112)='"+ dateTimePicker1.value.Date,con); //con is sqlconnection Sda.Fill(dt); Datagridview1.DataSource=dt;
In c89/90 is there a way to retrieve a pointer from stack or whatever that would behave as this would once cast to the correct type? This is more of a curiosity than a requirement.
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?
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.
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.
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?
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.
