C Sharp :: Search A Record In SQL Table Using Datetime Variable
Jan 1, 2014
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;
How to validate the data if the data already exist in the table record in c#?
For example I wanted to add the student roll no. if roll no. is 134 and if we are adding rollno. 134 student then we get the warning like roll no. 134 is already exist ....
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 am trying to get my program to search for the account ID in the structure and deletes the record as the account ID is found. The problem is that my codes are not working. (since my whole program is too long, I only show a part of it.) Here are my codes:
Below is a snippet of my code in which it loops through a file trying to find the matching record of a selection given by the user. I use tellg() to tell me where the search begins and it does in fact start at the beginning. But when the search actually executes, it starts at the last record, loops once, and ends, as it does not find the matching record (when the user enters '24' for example)
void Hardware::updateExistingRecord(ofstream &addRecordInfo, ifstream &updateRecord, Hardware &_records) { //selection on which field to update enum Field { RECORD_NUMBER = 1, TOOL_NAME, QUANTITY, COST, EXIT }; cout << "Enter record number you would like to update "; cout << "Enter zero to exit ?";
I have a C# .NET Application which get data from QuickBooks via the ODBC Driver and save the result to C# data table. So, I want to transfer this data table to a mysql table on my own server. That's the code I use:
using System.IO; using MySql.Data.MySqlClient; //Add mysql dll on the .NET Tab in Project's references string connStr = "DSN=QBTest;"; string myServerAddress = "192.168.0.243"; string myDataBase = "CostTest";
I want to display the content of my database in list view. The table has 5 columns however when I tried this code
string view = "Select * from cust_infor"; SqlCommand cmd = new SqlCommand(view,FL.clsconnection.opencon()); SqlDataReader dr = cmd.ExecuteReader(); listView1.Items.Clear(); while (dr.Read()) { listView1.Items.Add(dr[0].ToString()).SubItems.Add(dr[1].ToString()); }
It limits the display to 2 columns. List view will only show the first 2 columns. The code above won't let me add more indexes or subitems. Only up to 2 columns.
I have a Gridview ,in that one of the Column is DropDownList .I have 10 Records in my Grid and my DropDown Values are like this 1,2,3....10.This is the format to store my DropDown values ,if i delete 4th Row ,then my DropDown Values are Changed like 1,2,3,4....9.This is my task ,but i'm getting this format 1,2,3,--,5...10.
I have to develop a C program that reads a very complex txt file (output of a calculation code, so full of mixed text and numerical tables), search for a specific table in it and individuate/print or replace a specific value with assigned position in the table.
1st when i fill the things on form then saved in database after saving record when i want add another record it shows an error. after saving it saves new record refresh doesn't work
I have project "Time Table of school". How it possible logically as well as visually in .NET. it contain all teachers name and their periods. when any one absent then we enter the name of teacher or course name, highlight the absent teacher periods and then generate arrange period list and print it. when it highlight timetable we click on them and show all other teacher names who are free at this time.......
what controls are need in .NET with c#. it will be desktop application,
I am trying to work with C# and i am stuck here. My problem is i want to retrieve the count of all the users in a specific side. Let me Explain. Here is my table snapshot with sample data.
Now what i want exactly is that i get the count of users in a specific side as i give a user id as a parameter.The data is stored in MS Sql Database and i have to implement this on a website so efficiency of code is also a issue.
Suppose i give 1001 as input The output should be : Left:1 , Right: 8
if 1002 is input The output should be : Left:5, Right:0
if 1003 is input The output should be : Left:3, Right:0
if 1004 is input The output should be : Left:0, Right:0
if 1005 is input The output should be : Left:1, Right:1
and so on. how to implement this thing. I also want to get a code which would return an array of all child users of a particular ID in a hierarchical manner so that i could process that data with RadOrgChart Control.
im doing a program to store name, age, time and fitness. and i need to hold a table of 5 such records.can i do this?
#include <iostream> using namespace std; int name1, age1, time1, fitness1; int name2, age2, time2, fitness2; int name3, age3, time3, fitness3; int name4, age4, time4, fitness4; int name5, age5, time5, fitness5;
I need to save excel file data directely into oracle database by using XML string but getting error as
ORA-01704: string literal too long 01704. 00000 - "string literal too long" *Cause: The string literal is longer than 4000 characters. *Action: Use a string literal of at most 4000 characters. Longer values may only be entered using bind variables. Error at Line: 50 Column: 31
I would like to fill a combobox with particular field for example if i have atable with fields such as CustID, CustName, CustAge.
I would like to only fill the combobox with the Name filed such that only the CustNames will be field in the combobox and am able to write an event handler for the selected index.
I'm trying to write a program which prints a table of ASCII chars, I'm not really done with my thoughts on it but I already ran into the following error:
Error: cannot initialize a variable of type 'char' with an rvalue of type 'char (*)[16]'
Here's my code so far:
# include <iostream> using namespace std; int main() { char asciiTable = new char[8][16]; int nextSign = 0;
I am having trouble getting the cout statements that I commented out to work properly. And I can't figure out why the first movie in the movies.txt file displays at the end of the list in my output screen when it should only display once as the first item. I am also having trouble figuring out where and how to set up the static variable.
Purpose : This assignment requires that you to develop a program using the classes listed above. Specifically you will build a hash table containing movie data. The collision strategy will be to build linked lists as the array elements.
Program Specifications : Your program will read the data from the file named Movies.txt located in the StudentFiles1.zip file on the Connections Portal. Each record contains 2 fields separated by a space. They are:
FieldsData Type Motion Picture Association Code (MPAC)Integer Movie NameString
Your application program will read each record, create a Movie structure instance and place that structure instance into the hash table.
You will need to modify the appropriate code to provide for an audit trail of the hash table construction. To accomplish this, you will use cout statements in the above class member functions. You will need to modify them to include couts, but the modifications will be relatively small. If not, you are doing it wrong. The hashing algorithm to use is:
Index = int ( 0.618033 * MPAC) % size
Make the array size a constant and set it to 10.
Include a counter for the number of collisions that occurred in building the hash table. Including a static variable in the LinkedList or List class is the best method for doing that.
See the sample audit trail below for the first 5 records on Movies.txt and the size of the hash table set to 3. This is shown for illustration only. The full file will have different locations calculated.
1101-Casablanca is being added The hashed location is 2 There was no collision loading 1101-Casablanca ------------------------------------------------ 1200-Duck Soup is being added The hashed location is 0 There was no collision loading 1200-Duck Soup ------------------------------------------------
[Code] ....
After the above is displayed, prompt the user to enter the MPAC of a movie to locate. Produce an audit trail when locating the requested movie as shown below: Make sure you list all movies that have collided at the hashed location. That may also cause you to modify one of the existing ADTs a little.
Will search for 6601 at the hashed location is 2 There was a collision here with 6601-Wizard of Oz There was a collision here with 1101-Casablanca retrieved from hash table: 6601-Wizard of Oz
