C Sharp :: GET Values From Table In A Recursive Manner
Nov 14, 2013
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.

I am having an issue with my sort function. This is one part of the Hash table program. The main issue is that I am trying to sort the pointer table after all of the values have been entered. The ptr_sort function is not a class function and so I am therefore unable to use the class variables psize and pTable. Is there another way I should be trying this? it is a Vector should I use the sort() function from the vector class in STL?

Below, is the program I completed so far. I need to write a C program that reads in a stream of integer values, each representing an (x,y) pair on the cartesian plane. It then says I need to display the distance and direction from one point to the next. I tested it out, and it works.I need to use a conditional statement, and I'm a little confused how to display the direction(right, left, up, or down).I think I need to use an. "If" statement with my first one being something like:
If (y2 = y1) && (x2 > x1)
and I'm not sure what else to put,or if this is wrong. And with y staying the same and x increasing, the direction would be right.
Code:
#include <stdio.h>
#include <stdlib.h>
#include <math.h>
int main(void)
{
int x1, y1,x2,y2,x3, y3,x4,y4,x5,y5,x6,y6; //x and y coordinates

get my code to display a table with values from a file. my current code fills up all the sections of the table with the same data. here is what I need: from a file .txt I upload numbers that should show a table like this :
Lake Beach Average E-Coli Level
Recommendation
Ontario Kew Beach 47.12 OPEN Huron Goderich 51.13 CLOSED Simcoe Sibbald Point 0 INSUFFICIENT
my problem is in the last two columns. The ave. E-coli has one value for all which should look like the above table but my code doesn't. Also my recommendation shows the beach # instead of open close or insufficient.the data is:
Lake table
1: Ontario
2: Erie
3: Huron
4: Muskoka
5: Simcoe
Beach table
100: Kew Beach
101: Sunnyside Beach
103: Sandbanks
201: Port Dover
202: Port Burwell
203: Crystal Beach
301: Goderich
302: Sauble Beach
303: Kincardine
401: Muskoka Beach
501: Sibbald Point
the .txt file contains the following data:
1 101 5 66.6 33.3 22.2 98.9 11.1
5 501 2 33.3 44.3
now this is my code:
Code:
#include <stdio.h>
#include <math.h>
int main(void)
{
FILE *in;
}
[code]......
fix the two last columns so the correct info shows like the table above.

Am using the below code to INSERT values into MSI Database (Registry table)
private void button2_Click(object sender, EventArgs e) {
String Name1 = lblDName.Name;
String Value1 = txtDName.Text;
String Name2 = lblUnisntall.Name
String Value2 = txtUninstall.Text;
[Code] ....
This code work properly, but after inserting values in MSI database.
The Value1 and value 2 are created as REG_SZ (String) but as per my requirement,
Value1, should be REG_EXPAND_SZ
Value 2, should be REG_DWORD
Need to convert them in my code and then to insert into the MSI database.

how to rearrange lists in an special manner.
I have heard about the hashset but I do not fully understand how that thing works or if it is the best option for this issue.
Basically I have 3 lists: LIST1, LIST2 and LIST3.
LIST1 is a set of xyz points and LIST2 shows how the points are connected (clockwise, counter clockwise, coolinear).
For example the fact that in the first line of LIST2 appears 0, 1, 2,-1 means that the points in LIST1 are connected as follows:
(0 0 128.588459085565)->(25 0 134.979628462965)->(0 0 134.979628462965)
Same for line2 of LIST2: 1, 4, 2,-1
(25 0 134.979628462965)->(25 0 140.100717207301)->(0 0 134.979628462965)
etc...
The value -1 at the end of each line does not mean anything but I need to keep it.
Finally LIST3 tells me if the points are connected counterclockwise (-1), clockwise (1), or coolinear (0).
The thing is that I want to get things as follows:
If the values of list 3=1 then I need to extract all the points in the list 1 that correspond to the value 1 in order. However the values in LIST2 cannot keep being 1, 4, 2,-1 they need to be reorganised starting by zero. Expected result in LIST2= 0,3,1,-1.
We need to do this for each value in list3 (1,-1 and 0).
The idea is to get 3 groups of values:
- Group 1 including all the values that are clockwise (list3) with the points in order in list1 and showing connections starting from zero on in list2.
- Group 2 including all the values that are counterclockwise (list3) with the points in order in list1 and showing connections starting from zero on in list2.
- Group 3 including all the values that are coolinear (list3) with the points in order in list1 and showing connections starting from zero on in list2.
The idea is to be able to print 3 files in the following way:
FILE1:
Points which are clockwise in LIST 1
...
Connections of those points in LIST 2
...
FILE2:
Points which are counterclockwise in LIST 1

In my case, it involves making a wrapper class of sorts for the std::set. I'm wanting to go all-out on it and make some "fashionable" constructors for it, one of which being similar to C-style array initializations.
// C-array initialization.
int array[5] = { 1, 2, 3, 4, 5 };
// Some example usage of what I'm wanting.
Set<long> num_set = { 10, 20, 30, 40, 50 };
Set<std::string> str_set = { "Hello", "I", "am", "a", "set." };
I almost never overload operators when I work--if it can be done with a function, it's done with a function--but I realize that doesn't make the best user-experience when other people come across your code, so that's what I'm trying to improve.
It looks like I'm going to be needing to overload the = operator, no big deal. But the array segment is confusing, since {} is not an overloadable operator in C++.

Write a program that reads in the numeric representation of a date and prints it out in a formatted manner as the box below.
1. If the user entered an invalid number for the month it should display "Invalid Month"
2. If the user entered an invalid number for the date it should display "Invalid Date"
3. Check to see if the day is outside the range for that particular month
An example of the input and the output:
Enter the date: 1 24 2013
The date you entered is: 1242013
Im not sure on how to go about this problem, but this is what I have.
#include <stdio.h>
int main(void) {
int a, b, c;
int status;
printf("Enter the Date");
status = scanf("%d,%d,%d",&a, &b, &c);
printf(" The Date is : %d",status);
return 0;
}
Am I going about this right? Is there an easier or better way to go about it? All that happens is that the program reads the first number and spits that back out.

I am grabbing data from three entities and want to grab a field value in each of the entites and place it in an arraylist. What I would like to do is loop through the arraylist for all the values and do something for each value only once. If the value in the array list is repeated, I want to not do anything for it and continue till the end. Basically, I loop through all the values do something for each value and skip over the repeated value if I already did something.

If a user enters a string of boolean algebra it will ouput the table.
I have input parsing, cycling through the combinations, and outputing working. However once i parse the input I am not sure what to do with it. I have thought of having it write the parsed input to a new file as a function and then use that function, but that seems bad.
How to dynamically create the function, how to implement it.
BTW This is a console function, if that changes anything.

I have written an SQL statement that would:
1) Count the number of rows in the table booking that are open and where the booking.postcode is "MK",
2) Take a note of the plot (in booking.plot_id), and then update the table plot.jobs with the value count.
For example running the SQL query when booking table has the following rows:
Would see the following highlighted values in plot.jobs being updated to 1:
I managed to resolve it with this code so far (note I am using Connector/Net):
public void RefreshPlot(){
string query =
"SELECT Count(*) AS count, plot_id FROM booking WHERE postcode='MK' AND status='open' GROUP BY plot_id";
var cmd = new MySqlCommand(query, _connection);
var da = new MySqlDataAdapter(cmd);
var dtCounts = new DataTable();
da.Fill(dtCounts);
[code]....
Currently, my code only checks for existing rows in the booking table and updates the plot table. However if the row gets deleted in the booking, then the changes are not reflected in the plot table.
Example: If we delete the row with plot.id=1 and plot.plot_id=4, then booking.plot_id should go back to being 0, if it was initially 1. At the moment, it doesn't. How would I update my SQL statement to better reflect this? In a sense, it should check for "non-existent" rows, i.e. the impact that the row plot.plot_id=4 & plot.id=1 has on booking.plot_id when deleted?
