C# :: How To Represent A Table That Contains Dynamic Content In Header

Jun 2, 2014

I've attached an image that shows a basic table with dynamic content in the header.

Initially, I thought about using a datagrid. However, I can't use a datagrid because of the format of my data visually. The DataGrid would not allow me to have static and dynamic data inside my column headers.

You see anything I am displaying in brackets, {}, are being updated with results after I process some data in the backend. After the data analysis is done, the results are displayed based on an algorithm.

So, let's say for control1, for each family, it would indicate whether the data passed or failed. Then, in the rows themselves, it would update with choice 1 or choice 2 depending on the data generated.

So, the data that is in brackets shows properties being updated. I'm not sure what UserControl I can use to accommodate this kind of display.

C# :: WPF Using Color Resource In Rectangle Stroke Color

Sep 7, 2014

Trying to define some global colors so I can use the one instance though-out my application. Here is my color code:

<Color x:Key="GlobalTextColor">#E0E0E0</Color>

But this color doesn't display in the list when I start to type {StaticResource ...}

This is the code where I'm trying to reference the color, see Stroke="{StaticResource GlobalTextColor}". GlobalTextColor doesn't actually come up in the list so won't work.

C++ :: Hash Table Program - Sorting Pointer Table After All Of Values Entered

Nov 19, 2013

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?

#include "/home/onyuksel/courses/340/progs/13f/p9/util9.h"
#include "/home/onyuksel/courses/340/progs/13f/p9/hTable.h"

#ifndef H_TABLE1
#define H_TABLE1
void ptr_sort ( );

C++ :: Truth Table Generator - If User Enters String Of Boolean Algebra It Will Output Table

Jan 25, 2013

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.

C# :: Lookup Non-existent Rows In MySQL Table And Then Update Another Table

Dec 15, 2014

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?

C# :: Use Table Adapter With Textboxes To Edit SQL Table?

Mar 8, 2015

I am a bit stumped with trying to write some code to get the tableadapter/binding source to "update" a current 'user' to the table.

I have the insert/delete methods working fine, but it's the updating that has got me screwed up.

Example of insert.

try
{
personTableAdapter.Insert(tFirstName.Text, tSurname.Text, Convert.ToDateTime(tDoB.Text), tPhone.Text, tAdd1.Text, tAdd2.Text, tSuburb.Text, tState.Text, tPostcode.Text, TeacherType.Text);
teacherTableAdapter.Insert(Convert.ToInt32(tTID1.Text), tRegNo.Text, tPassword.Text);

[Code]....

I also tried to do the updated string/original string with the tableadapter.update, but that didn't work either.

C++ :: Calling A Function From A Header To Another Header?

May 16, 2014

I'm doing a compiler, and I'm using writing everything in headerfiles.

at the moment I have lexer.h, token.h and for this case I need reservedWords.h

reservedWords.h is made up of enums showing the needed words

in token.h I have a function called reservedWords reservedLookup(string str) which returns a reservedWord (enum)

now in lexer.h I have a function called Token* getNextToken() in which I need to make use of the function reservedLookup found in token.h

note that all of them are classes apart from reservedwords as in

class Lexer
{
public: .....
}
class token
{
public .....
}

how I can call that function?

I tried declaring reservedWords reservedLookup (string str) BUT obviously it's directing me as Lexer::reservedLookup and not as Token::reservedLookup

When I tried using Token::reservedLookup it gave me

E:Universitycompilerslexer.h|65|error: cannot declare member function 'Token::reservedLookup' within 'Lexer'|

N.B I use namespace std, that's why I didnot write std::string str
