C# :: Link Multiple Tables In Crystal Report With Foreign Key
Apr 2, 2014
i have 2 tables with primary and foreign key
Customer Details
EID - Primary Key
PurchaseDetails
PNo-Primary Key
PDate,
EID- Foreigh Key
NetAmount
Report Query written in c#
SELECT DISTINCT P.PNo, P.PDate, P.PM, P.DisAmt, P.LT, P.NT, P.EID, P.PTime, C.EName FROM PurchaseDetails AS P INNER JOIN CustomerDetails AS C ON P.EID = C.EID
I created a dataset that contains an empty dataTable that has several columns , and then I created a new report that is linked to this datatable using the report wizard. In my form there is a button when clicked should fill the datatable mentioned above ( I checked if it is being filled by displaying its content in a dataGridView and by firing a messagebox that is triggered when 'datatable.rows.count > 0' ).
The reason that the datatable is initially empty is that it depends on some conditions that may alter the query used to fill it.
But finally when I load the form that has the report viewer it only has the names of the columns of the datatable and no contents. What's wrong ?
I'm having a bit of trouble with something. What I'm trying to do is create a new Access table by combining other already existing Tables.
For instance, let's consider Table1 (with columns A, B and C), Table2 (with columns A, D and E) and Table3 (with columns A, F and G), where Table1.A = Table2.A = Table3.A.
From these, I want to create a new table TableResult, with columns A, B, C, D, E, F and G, with all the data contained in them. There's one catch: I want the code to get the names of the other columns, apart from column A.
I've thought about using Union, but I need to actually create a new table by combining the previous tables.
I have downloaded this project from here -->> [URL] ....
This one works fine and it's a great commented code to understand even for beginners like myself, but it only works with one table per sheet. Once I add second table in sheet, it throws an error that something is wrong in one of the columns in my spreadsheet: It says: " Error occurs! The error message is: Cannot find column 4. "
Basically, I have this type of tables in my spreadsheet:
So I want that my program would export those two tables in a single .XML file (just read them both). And those two tables should be separated in two XML childs: the upper one should be Order-Header and the lower one - Line-Items, like this:
I copied all the code because I think it is the easier way to spot where to change it, to read those two tables in one spreadsheet and export them both in one XML file. How could I achieve this kind of functionality.
I receive unexpected outcome in my program. Instead of getting all combinations of 0, 1, 2 (i.e. 000, 001, ..., 222) I get only 000 001 002 010 011 012. The idea of the progarm is to create a crystal lattice. Each atom of the lattice has 3 coordinates (x, y, z). That's why I create class Atom. Then I create 3-dim array of the type derived from class Atom. Now each element of the class will represent an atom.
Code: #include <iostream> using namespace std; class Atom { public: float x, y, z;
The report works in my computer. But when I deploy to another computer, it doesn't work. It got login in prompt. I used SqlClient to get data then bind to DataSet, then set report source.
My environment: XP + VS 2003 DataBase : MS SQL 2005 (another server) System : Windows Form
I need to run some basic statistics on about ~150 tables that are currently in dBase format. Rather than use excel to do them all individually, i was told to use s+ and write a code to loop through them, but I have never written any code and my experience with spotfire s+ is limited (the stat software i have available) ....
In my code I have lots of structures. I try to make tables of structures and then get access to elements of the structures to use them all along my code: here is an example to clarify things
typedef struct { Fabric **closfabric; }Network;
Net is part of another structure called Switch and Fabric itself is a composed structure. I have done the following
The compilation returns a segmentation fault because aSwitch->net.closfabric is NULL (0) .
Surprisingly, in other codes the same analogy of using tables made of double pointers works perfectly with no problems and I have no problem of core dumped and NULL pointers.
Why am I getting this problem. It is the case whenever I try to use large dimension tables (tab *** struct for example)...
I am creating 5 different tables each one has 20000 more elements more than the previous when i try to sort them with the sort algorithm quick sort for the first table tha has 20000 elements runs grate then it throws this exception how is this fixable ?
Exception : terminate called after throwing an instanceof 'std::bad_alloc' this application has Requested the Runtime to terminate it in an unusual way. Please contact the applications's support team for more information. Process returned 255(0xFF) . here is the code that gives this return :
Code: #include<time.h> #include<stdlib.h> #include <string.h> #include <ctime> using namespace std; int * Create_Table(int table[],int N);
Currently I have to manually look up values on several different tables in different locations. I have 8 or 10 tables with 100 to 500 parts.
I would like to write a program so if I enter a value it will return the corresponding correct answers from the tables.
If I entered 2.5 for a value it would return the following three items from the tables since they all meet the requirement.
Table 2 Part min max 235 2.4 2.9
Table 6 Part min max 589 2.3 2.5
Table 7 Part min max 12 2.3 2.7
What would the best method be for setting up and accessing tables like this? Is C++ good at representing something like this or should I be looking at a different language?
What I would like to happen, when I run my code is that I'll get the following
Item_ID, Name, parent_Name 1 , jeff , jackson
DataSet DS = new DataSet(); if (this.OpenConnection() == true) { mySqlDataAdapter = new MySqlDataAdapter("select Item_ID, NAME, Parent_ID from table1, table2", connection); mySqlDataAdapter.Fill(DS); dataGridView1.DataSource = DS.Tables[0]; //close connection this.CloseConnection(); }
So this spit out parent ID = 5.
I've not worked with Dataset before and I was just wondering what is the best approach? Can this be done via a SQL command or will I have to replace the value(5) with the string(jackson) using a large IF loop to search and replace.
I'm trying ultimately to do a radix sort. I'm going with the implementation using two tables. One will initially hold the unsorted values then hold the partially sorted values thereafter. The other will be an array of linked lists which will be where the radix sort is done. Here is my code thus far:
Main
#include <iostream> #include <fstream> #include "radix.h" #include "radix.cpp" using namespace std ; int main ( int argc , char * argv [ ] ) { ifstream input ( argv [ 1 ] ) ;
[Code] ....
It appears to be crashing during void insert_into_sorted ( int to_insert , int place ) ; and I'm not sure why.
i have project (person ID cared) and fortunately i could finish it in programming,,,,, but the thing that i don't know what to do about it is how to print this data? can i use reportviewer ?
I need to show in a comboBox thats shows infor from Entity framework but i need to select a specific colum in the tables..
All in C# visual studio xaml form
So I created a var but i get and output: name of programe.NLHEntities
using (var context = new NLHEntities()) { var blog = context.EtagesChambres .Where(b => b.TypeChanbre == "Prive") .FirstOrDefault(); textBox2Type.Text = Convert.ToString(blog);// i put a text box to see what the output would be.. }
I'm trying to write a table (2D array) with a string of random chars in one row for the student names, six other rows for the project numbers and random numbers for the grades.Then calculate the averages of grades per student and per project, add them as the last row and the last column. And write a menu of 4 options:
1- sort per student names (alphabetical order) 2- sort per student grades (in increasing order) 3- sort per project grades ( in increasing order) 4- exit
The program must continue execution after displaying any report, need to use an infinite loop, it exits only if the chosen 'exit'.
It cannot loop back to the top coding, cause what i want is the code can loop back to the 1st cout question, and it will asking over and over again, and how to declare a function for the summary report?
I have a table in sql called empattendancetable the fields are
eid empname designation logindatetime status emp001 abc manager 30-05-201412;00PM present
likewise i want to display the month wise attendance details of all the employees
the logindatetime field value from datetimepicker i am not getting how to write the query to get the month wise detailsusing c# i am creating a windows application to maintain the details of employees
