For my Arduino project, I want to have a class called Buttons, that has six EasyButton instances as members. I want to pass the pins of the EasyButton instances to the Buttons constructor. How can I instantiate the six EasyButton members of my Buttons class in the Buttons constructor?
#include <EasyButton.h>
uint32_t debounce_time = 200;
bool pullup_enable = true;
bool active_low = true;
class Buttons
{
private:
public:
Buttons(uint8_t pin1, uint8_t pin2, uint8_t pin3, uint8_t pin4, uint8_t pin5, uint8_t pin6);
// do the following in the constructor.
EasyButton button1{pin1, debounce_time, pullup_enable, active_low};
EasyButton button2{pin2, debounce_time, pullup_enable, active_low};
EasyButton button3{pin3, debounce_time, pullup_enable, active_low};
EasyButton button4{pin4, debounce_time, pullup_enable, active_low};
EasyButton button5{pin5, debounce_time, pullup_enable, active_low};
EasyButton button6{pin6, debounce_time, pullup_enable, active_low};
};
This can be done with an initialiser list
class Buttons
{
private:
public:
Buttons(uint8_t pin1, uint8_t pin2, uint8_t pin3, uint8_t pin4, uint8_t pin5, uint8_t pin6);
EasyButton button1;
EasyButton button2;
EasyButton button3;
EasyButton button4;
EasyButton button5;
EasyButton button6;
};
Buttons::Buttons(uint8_t pin1, uint8_t pin2, uint8_t pin3, uint8_t pin4, uint8_t pin5, uint8_t pin6)
: button1(pin1, debounce_time, pullup_enable, active_low),
button2(pin2, debounce_time, pullup_enable, active_low),
button3(pin3, debounce_time, pullup_enable, active_low),
button4(pin4, debounce_time, pullup_enable, active_low),
button5(pin5, debounce_time, pullup_enable, active_low),
button6(pin6, debounce_time, pullup_enable, active_low)
{

I am trying to implement the IInternetSecurityManager on a WebBrowser control in order to override some IE security restrictions.
I have extended the WebBrowser control (call it MyWebBrowser) and have subclassed the WebBrowserSite class (call it ExtendedWebBrowserSite), and I've overridden the CreateWebBrowserSiteBase method on MyWebBrowser to return an instance of ExtendedWebBrowserSite.
class MyWebBrowser : System.Windows.Forms.WebBrowser
{
protected override WebBrowserSiteBase CreateWebBrowserSiteBase()
{
return new ExtendedWebBrowserSite(this);
}
}
My ExtendedWebBrowserSite class implements IServiceProvider and IInternetSecurityManager interfaces:
class ExtendedWebBrowserSite : WebBrowserSite, IServiceProvider, IInternetSecurityManager
{
// constructors omitted...
// IServiceProvider implementation
public int QueryService(ref Guid guidService, ref Guid riid, [MarshalAs(UnmanagedType.Interface)] out object ppvObject)
{
if (guidService == SID_IInternetSecurityManager && riid == SID_IInternetSecurityManager)
{
ppvObject = this;
return HRESULTS.S_OK; // = 0x0
}
ppvObject = IntPtr.Zero;
return HRESULTS.E_NOINTERFACE; // 0x80004002
}
// IInternetSecurityManager implementation ommitted...
}

[return: MarshalAs(UnmanagedType.I4)][PreserveSig]
int GetZoneMappings(UInt32 dwZone, out IEnumString ppenumString, UInt32 dwFlags);
}
Results
The QueryService method is called when the WebBrowser is initialized. However, right after the QueryService method finishes and returns HRESULTS.E_NOINTERFACE, an AccessViolationException is thrown:
AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
at System.Windows.Forms.UnsafeNativeMethods.IOleObject.SetClientSite(IOleClientSite pClientSite)
at System.Windows.Forms.WebBrowserBase.TransitionFromLoadedToRunning()
at System.Windows.Forms.WebBrowserBase.TransitionUpTo(AXState state)
at System.Windows.Forms.WebBrowser.get_AxIWebBrowser2()
at System.Windows.Forms.WebBrowser.set_ScriptErrorsSuppressed(Boolean value)
Note: None of the IInternetSecurityManager methods get called, because QueryService never gets the chance to assign an implementation of it. So I omitted the IInernetSecurityManager methods for brevity.
Anyone have any ideas as to why this could be happening?
The following, when compiled, produces a "1 unresolved externals..."
My question is - what are the proper parameters?

Ui.cpp:

The compiler error will say the line number for the question you originally asked.
However, it looks like you have
namespace Spammer2 {
//lots of usings
public ref class Ui : public System::Windows::Forms::Form
{
//lots of other stuff
}
};
You need to end the class definition with a semicolon, not the namespace:
namespace Spammer2 {
//lots of usings
public ref class Ui : public System::Windows::Forms::Form
{
//lots of other stuff
}; //<-------
} //<-------
Edit:
Since the question has now changed, if this is all your code add a main to UI.cpp
#include "StdAfx.h"
#include "Ui.h"
int main()
{
}
I would like create my CustomQSpinBox .
This CustomQSpinBox must inherit of QPushButton and QSpinBox
but when I compile this code :
#include <QSpinBox>
#include <QPushButton>
class CustomQSpinBox : public QSpinBox, public QPushButton
{
Q_OBJECT
public:
CustomQSpinBox (QWidget *parent = 0);
~CustomQSpinBox ();
void initMinMax(int min, int max);
void init();
signals:
void needNumpad();
public slots:
void clicked();
};
I get an error :
erreur : C2594: 'static_cast'ÿ: conversions ambigu‰s de 'QObject *' en
'CustomQSpinBox *'
How I must do my inheritance ?
Yes, when the numPad is closed, the value is set in the QSpinBox. The problem is so to open the numPad when I click on the QSpinBox.
For the moment I manage with this code :
#include <QSpinBox>
#include <QPushButton>
#include <QMoveEvent>
#include <QResizeEvent>
class CustomQSpinBox: public QSpinBox
{
Q_OBJECT
public:
CustomQSpinBox(QWidget *parent = 0);
~CustomQSpinBox();
void resizeEvent(QResizeEvent *event);
void moveEvent(QMoveEvent * event);
signals:
void needNumpad();
public slots:
void clicked();
private:
QPushButton * button;
};

The problem at hand is that your namespace and your form class both share the name Form1. You have to disambiguate the symbol by specifying that it's the class within the namespace.
Application::Run(gcnew ::Form1::Form1());
