what I need to do is load a dataset with the most recent record for each item in the database table. Each item has an ID, location ID and date along with some numeric data. the item ID, location ID, and date is referenced in each record of the table. So each item will have multiple records with different dates that could be anything. To make things worse there may be the same item in multiple locations. and each locations items most recent record needs to loaded in to the dateset and then displayed in a data grid. At a later time there will be a location sort as well so only items in a particular location or group of locations will be loaded. More question on the data grid to come.
I'm trying to create a web service that uses a dataset called dsPeople, but it doesn't seem to know where it is, and gives me a directive/namespace error underneath it where it occurs. Do I need to declare it somewhere or something?
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Services; using System.Data; using System.Data.OleDb; namespace WebServiceTest
How would I go about shrink the duplicate data set from CWorksheetTwo? For CWorksheetTwo has both CUser and CUserEx, and I only need CUserEx, and all other classes are happy with CUser
Since there is no such thing virtual variable what are my choices? In CWorksheetTwo set users to NULL and use another exclusively? Change CSettings variable to template <class T> std::vector<T>users?
Is there a way to indicate how many records exist in a given file? For example, vectors have the vector.size() command to show the number of given elements. Is there a such command for files and records?
Is this the right codes for deleting a recoed on the text file.
void dlte(){ string line, recorddate; cout << "Please Enter the date of record you want to delete: "; cin >> recorddate; ifstream myfile; ofstream temp; myfile.open("herald.txt");
I have to ask the user if they want to delete any records. The user can enter -1 to finish deleting records. I have to write the remaining records in an output file. So, i have this, but
1) it doesn't let me enter more than 1 id, and 2) it doesn't output anything to my output.txt.

In my form, I'm adding new records in the datagridview. However, for some reason only the first column of that datagridview is updated. Then I tried to clear out the other codes and left the code for the datagridview. Apparently, I failed. Then I tried creating a new form with the same design and code. And it works out pretty well.

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 have got 4 radio buttons on my form and & i am trying to match the text for these radiobuttons with a record in one of the database tables. Essentially I would like when the submit button is clicked to match if the selected or clicked radiobutton Text with a database record. And if this matches a messagebox to be displayed saying "match" and if not matched the messagebox should show "no match found"
in this case the "Emp_1" is the matching record , when I run my project when other options or radio buttons are clicked it executes the messageBox showing that it matches even if its not a matching record. What I am trying to say is that it does not execute the else {MessageBox.Show("no match found");} when records don't match.

I am increasing my array in multiples of 5 (or in this case, my constant BLOCK). This is the result of my printout (t1-t40 is correct, the rest of the values should be 1):
t1 1 1 t2 1 1 t3 1 31329 t4 31297 1 t5 1 31249 t6 31217 1 and so on .....
I noticed that in my test, realloc was called 7 times. My array has 7 distorted records. Each time I call realloc, it is distorting one of my records.
