I have a dialog of radio buttons, 100 of them
I use this to select type of material product is made from so I can select correct ink for printing. Selections are everything from alumininum, plastics to wood.
I would like to select 1 radio button and have it return
the int of that selection without having to add an event handler for each and everyone of the radio buttons
Is there a routine that can handle any check on any button?
If(any button is checked) return(int # of the button)
you have busted my bubble.
To me, it seemed easier to look at a dialog page
with radio buttons rather than search a listing
especially for my printers who may not have to learn how
to use drop down list boxes
Seems to me that the program knows when a radio button
is selected and then marks is as such and turns off all others in the group..
I was hoping I could intercept the routine and just
add my own function to it.

I have 3 functions that do sorting on a CArray.
CArrays are declared in header file:
// Do sorting for m_Integer here
// DO sorting for m_String
// Do sorting for m_Double
Now what i want to do is, have one generic function and then pass the CArray to that.
So far what i did is,
in Header file:
void sortAll(CArray<void*,void*> m_Array);
in CPP file:
void sortAll(CArray<void*,void*> m_Array)
int size = m_Array.GetSize();
m_Array.GetAt(0); // Error here
The error is that, it needs a class type and not a void type.
I am not sure how to proceed with writing a generic function to handle all different data types in one.
Any help is welcome!
I need to work with callback functions between different classes. With VS2010 I have done this already different times without any problem.
With VS2015 I cannot compile such code!
in Header in Class Declaration:
bool ProvideItemData(int nItem, int nSubItem);
//using namespace std::placeholders; // for `_1`
m_ListCtrl.SetOwnerData(std::bind(&CBlockEditView::ProvideItemData, this, std::placeholders::_1));
declaration in called class:
bool SetOwnerData(std::function <bool(int nItem,int nSubItem)> callback);
When compiling in VS2010, I get weird error messages:
c:\program files (x86)\microsoft visual studio 14.0\vc\include\type_traits(1501): error C2440: 'return': cannot convert from 'std::_Unforced' to 'bool'

I do not find any solution. So at the moment I do not have any idea, how to solve this issue!
1. I set tab order for control in a MFC dialog.
2. Started the application.
3. Clicked a button in dialog, whose tab order is 3.
4. A modal dialog displayed.
5. Closed the modal dialog.
Now the focus automatically moved to the control having tab order 0.
Since the focus was on the button just before the click, I would like to retain the selection on the same button.
