C Sharp :: Updating String Values Into Custom Data Xml Field
Feb 23, 2014
I have a variable named Authors. Sometimes I will insert one author into the database, sometimes more than one author will be inserted into the database.
The page that performs the update is a .cs page. Here is the layout:
using System;
using System.Collections.Generic;
using System.Configuration;
using System.Data.SqlClient;
[Code]....
This definitely works for updating one author's name:
if (old.Author != Author) RequestItem.UpdateField(LibraryDocID, Editor, "Author", Author);
I just can not nail down how to insert a string of author's names.
I want to search for the "movie_code" and change the [movie_status] from Active to Inactive.
So lets say for example i have a movie code 12345 saved in my movie file. I want to change the value from "Active" to "Inactive"for argument sake.
This is the code i was trying to do it with:
FILE *movie_fp; movie_fp = fopen("movie.dat", "r+b"); int m_code; MOVIE movie_data; printf("*** Welcome to the movie updater! *** "); if(movie_fp != NULL){
I just wanna update my database with one click only.
I do for update my database from datagridview1 but it shows a error like this :
Unhandled exception has occurred in your application . If you click Continue, the application will ignore this error and attempt to continue. If you click Quit,the application will close immediately.
Update requires a valid UpdateCommand when passed DataRow collection with modified rows
I am developing 1 desktop application to my friend office,in that application i can store multiple images and i can retrieve the information for the same..My issue here is after retrieving the information when i click on update button I'm getting runtime exception i.e (Empty path is not legal exception)..
Here is the code which I wrote under updatebutton method:
public partial class CustomerDetails : Form { string imageloc = ""; string imageloc1 = "";
class Excuse {... public string Description { get; set; } public string Results { get; set; } public DateTime LastUsed { get; set; } public string ExcusePath { get; set; } ....}
[Code] ...
When I run it, I do get the messagebox popping up with the correct description, but then nothing happens. When I debug, I see the fields under the UpdateForm() method are set to null.
I'm guessing this happening because it is looking at the 'currentExcuse' that was declared in the form body. I thought however that redeclaring 'currentExcuse' in the method would overwrite this instance or am I wrong?
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 am writing a program that manages a group of tool bins. This group is handled as an object that is an array of two element structures called InvBin. I initialize the bins with data from a file which contains the descriptions and initial quantities. I also have functions to add or subtract items from a bin and a function to display a report of the description and quantity of all of the bins.
The add and remove functions work correctly based on the cout statement in the functions, however when I display the report, it displays the initial quantity instead of the new quantity. In addition, when I use the add and remove functions again on the same bin, they use the initial quantity.
These are the add and remove functions and the report function from the main program.
Code: //Adds an item to a bin void addItem(HANDLE screen, BinManager tools, int &count) { int binNum; int addNum; system("cls");
This code is working totally fine. Right now, I'm trying to update a specific data from the student info. Let's say I'm trying to update my student number of Daniel. So, in this case, I want to replace 6744590 to some other student number. I think I have to use fseek() or rewind() and use fputs() but, I don't know how I should decide where to look.
And it will keep updating like this and I want to update the previous numbers I extracted with now the new numbers after the 4,5, and 6 space.
So I have to write a code to let it know when it encounters [ [ start looking for the 4,5,6 space and get those numbers and once it reaches ;... that's the end of that section so re-look for the next section of numbers after the 4,5,6 space.
The file will be a text file or matlab file that is always being updated with these sections of numbers. Can I make this a #include<nameoffile.h> or does .h not work with a file that is always being updated.
I have a problem I am working on where I need to sort some data based on the values of a string of bits. The strings look like this,
010000001110000000
there are 18 bits, 1 means a feature is present, 0 means the feature is absent.
Each of these string has 4 on bits. I need to sort them such that I have the longest possible runs with 3 of the same on bits. It doesn't matter which 3 bits are on, I am just looking to order them in blocks with the longest possible runs. As a second step, the ordered blocks will be sorted by size large>small.
The following data is ordered like I need it to be.
Code: // block 1, run of 12, keys 1,2,11 are identical (key 12 is also identical) 011000000001100000 011000000001100000 011000000001100000 011000000001100000
[Code] .....
This is the sort order that I am looking for. I need to be able to take a list of the bit strings in any particular order and sort them into the order above. The algorithm would need to recognize that there are 4 on keys and then look for groupings of three common on keys.
This is more of an algorithm question than one about specific implementation in code. I generally assume that most programming problems have been solved one way or another, so I don't know much about analyzing and manipulating strings of bits.
Is there a standard method for this kind of pattern recognition?
I am writing some code that takes a string of n letters, so a, or aa or aaa or aaaa...a and transforms these into d or dd or ddd or dddd...d by essentially counting. e.g aaaa -> aaab -> aaac -> aaad -> aaba and so on. Also technically the user inputs what the ending is whether it be d or e,f,g; however, for practical reasons counting up to dddd should work. My main issue is I am having trouble getting the letters correct. I get up to aadd and then once I go to abaa I have trouble getting the second to last a to switch correctly.
Code: #include<iostream> #include<string> #include<vector> using namespace std; int main() { vector<string> pleasework; string apple = "aaaaaa"; int end = apple.size()-1;
class DataBase { // Change the connection path here to your own version of the database public SqlConnection con = new SqlConnection(@"Data Source=(LocalDB)v11.0;AttachDbFilename=|DataDirectory|UberDatabase.mdf;Integrated Security=True;"); public DataBase() { } }
And in the same namespace as this class I have a form that calls it like so:
DataBase dBase = new DataBase(); SqlCommand trythis = new SqlCommand("Register", dBase.con);
However, I'm getting the field initializer error on dBase.con. I'm not sure why, but when I call the database from another file (program.cs) it works fine this way.
I m making calendar in server control page by taking composite control.I am also adding textbox in each cell of calendar. Now i want to access the value of each textbox of selected month and respected date in default.aspx page on button click event. Here the button is not a custom control but defined in default.aspx page..
Can't access textbox text and date or controls of server page in website(default.aspx) page.
I was wondering if this was even possible and if so, how do I do it.
else if (speech.ToLower().Contains("truck") && speech.EndsWith(number)) { Here I would like to see if my speech had ended with any of the values i would have stored in the string "numbers". If it did, I would like to just take the value and add it to a new string called whatever }
I have tried this a million different ways and I cant get it to work. I'm not even sure how I would go about storing tons of different numbers in one string, or if that's even possible.
I have an ms access database with 2 tables in it which I named Customers and Products. I am using visual studio 2010, in my windows form I have 4 textboxes and 3 button in it, for my 1st textbox when I entered one of my ProductCode such as 10111, then press the Display button, the other remaining 3 textboxes should populate and display the following;
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 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.
I want to store values permanently in a variable. The same variable should be able to be edited and saved by user, and whatever it is I need the value of the variable from the last time I modified it, like a database. database because i need this to set my connection string of the database.
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.
