this time i wanted to make a class i created static inside another class.
MainVariables.h file
static fge::window mWinMain;
if someone ever wants to reach it
MainVariables.cpp file
fge::window MainVariables::mWinMain;
...
...
fge::window MainVariables::GetWinMain()
{
return mWinMain;
}
but when i created some other MainVariables classes at other places instead of them reaching to the same window two window is being created.
yes i know maybe there are better methods but currently i m working on polymorphism and i need some static members.

View 1 Replies View RelatedI have three tables (company,department and employee). Company table has two rows (CompanyID, CompanyName). Department table has four rows (DeptID, DeptName, CompanyID, EmpID). Employee table has three rows (EmpID, EmpName, EmpAddress).
I want to search by Departments For example I want to have one Checkbox named Department if I checked Department it should show me all the available departments in the Company so if i select a particular department it should show me all the employees that they belong to the department that has been selected.
I've got a calendar in Form 1 in my code, and buttons in Form2. I need these buttons to send codes for this calendar in Form1. How may I make these work? My friend told me to do a function as a new class, but I'm not sure how can I do this.
View 5 Replies View RelatedI am busy with a project, it is going to consist out of 3 different windows which is logic enough for this whole code to be interactive.
It must be able to pull data into a windows form, displaying it into a textbox, and when you click on the textbox it needs to open up another window where you will have a windows form that will display data as the code loops through the questions in the database.
I am not sure how to push the data that has been selected on the database to the next window..
Here is my code for the first window:
;
namespace WindowsFormsApplication1
{
public partial class Form1 : Form {
//SqlConnection myConnection = new SqlConnection("Data Source=(local);Initial Catalog=KnowledgeEssentials;Integrated Security=SSPI");
//int intType = 0;
public Form1()
[code].....
With the second window the data in the table needs to be displayed and each row from the table needs to have a checkbox next to them, so that if the check box is checked, the relevant information of the checked row will show up in the 3rd window... so MY question is, HOW do I pull that data from that specific database and let it show in the listcheckbox?
I can't seem to make the STL iterator class work how I need it to.I am implementing a multi list graph and I need to iterate through my STL list of Vertex pointer objects. I keep getting the error:
Error 1 error C2679: binary '=' : no operator found which takes a right-hand operand of type 'std::_List_iterator<_Mylist>' (or there is no acceptable conversion) and the same for != for my terminating condition.
template <typename V, typename E>

list<Vertex<V>*>::iterator iter;
for(iter = m_Vertices.begin(); iter != m_Vertices.end(); ++iter)

Just mark the destructor final: [URL] ....
Well, sort of - my question is, since the destructor has to be virtual in order to be marked final (you get an error otherwise), does this cause virtual function overhead anywhere, or add a vtable?
I want to make Class for 2D array.
This is part of Class Definition.

I have a class like this:
file one :
Code:
class X : public Y {
public:
virtual int query(int, int);
// constructor
X(int, int);
[Code] .....
And i construct my M and Nby calling :
Code:
X Y(a,b); and afterwords by calling
Code:
result = Y (c,d) i get my result.
The problem is I need to be able to call result = Y (c,d) from outside my main function and get results but i don't know how to do this. So I want to be able to do something like this.
Code:
#include <iostream>
int g;
void func2(int *h){
*h = g;

can we make a class without any data member ? but it may have member functions ! in c++

Public:
A (int);
A(int,int);
int get (int,int);
};
make a class that you can make only one Object of it.
For example if you have Class A.
Let's say you create one object A* a=new A();
Now the next time you, try to create another object. For example:
A* b=new A(); What will happen is that b will get the same object (or reference) as a. In other words hey'll be pointing towards the same place. So basically you'll only have one object of it created. I tried doing it but I couldn't quite make it.
Here is what I tried: (but couldn't complete the exercise)

I am given 2 methods and they want me to create a stand alone class for sql that will change the sql string.
my question is how can i take these 2 methods and make one class out of them that will used on various other forms.
#1
public string AuthenticateWithDB(CUiPontisDatabaseSpecification pdb, string sUserId, string sPassword,
bool bCreatePersistentCookie)
#2
public static void ChangeConnection(Util.ODBC.ODBCDSN odbcInfo, CPonDatabaseVendorType dbType, string uid, string password)
they want it so they can use it like
CUiHttpSessionManager.SimpleDataConnectionString = SomeNewClass.CreateSimpleDataConnectionString()
where some new class is my new class
is this possible to make a class without any data member in c++ ?

The question says that:

But then the 2nd part of the question itself says that "Acno entered by the user". So we need to identify/search for an account with that Account Number. How can we do this without comparing Acno with S.Acno? I know that S.Acno is not accesible as it is a private member but then how to compare Acno without even using a member function(public) that can return the value of Acno?

I am trying to make a table class that will be able to have multiple columns of data. I want it to have something to hold data (I was using a 2D vector for only one data type) in it, somewhat like a pair, but for any number of data types. The class is a template to make it generalized.
I have looked a little at variadic templates, but I don't know how to declare the vectors for each data types then.
I'm using Visual C++ 2010 Express on Windows 8. What I want to do at the moment, is to create a class to make WinHttp requests easier. This is the code that I'm basically using to build the class: [URL] ....
This is what I got so far. (Completely untested). Example of how I hope that it will work:
HttpRequest MyRequest;
MyRequest.Initialize("Mozilla/5.0 (Windows NT 6.2; WOW64; rv:28.0) Gecko/20100101 Firefox/28.0","","");
htmlCode = MyRequest.SendRequest("www.cplusplus.com","GET","");
