If the salary calculation is the only thing that's different between employees and contractors then I suggest you try something like the following
class contr_salary_calc
{
public:
int operator()( employee& E )
{
}
};
class perm_salary_calc
{
public:
int operator()( employee& E )
{
}
};
class employee
{
public:
employee()
{
m_bPermanent = false;
}
void calculate()
{
if( m_bPermanent )
{
m_PermCalc()(*this);
}
else
{
m_ContrCalc()(*this);
}
}
void MakePermanent()
{
m_bPermanent = true;
}
private:
bool m_bPermanent
contr_salary_calc m_ContrCalc;
perm_salary_calc m_PermCalc;
};
Somtimes there's nothing wrong with a little if..else logic when the word is little less static than your class hierarchy.

How can I subclass or create a popupmenu in another application?
I use a WH_CBT Hook to be informed when a special window is created. Now I'd like to add popupmenus to all
of the application's buttons or alter existent popupmenus.
Any ideas?

Hi, so here's my problem:
Basically I want to format a CString such that the trailing zeroes are all eliminated.
For example, let's say I have a double such as: 610.15100000
And I want to print this to a CString so that I can set the text in an edit control.
Right now I do something like this:
CString strTemp;<br />
double fVal = 610.151;<br />
strTemp.Format(TEXT("%lf%), fVal);
But in the edit control, it shows up with all the zeroes at the end:
610.15100000000
How do I make it print so that it shaves off the extra zeroes at the end?
Thanks!

Assuming you want three places after the decimal, use:
strTemp.Format(TEXT("%.3f"), fVal);If, however, you are wanting to remove all trailing zeros regardless of how many, see the TrimRight() method.

The above will fail on fVal = 1.051000 (provided I understood his requirements).

Actually it fails also on his input (610.15100000).

How so? strTemp has a value of 1.

It worked fine for me. strTemp has a value of 610.

But it needs to be 610.151. Thanks though!

So use .3 instead of .0 then.

I think he wants to remove trailing zeroes in a general way, i.e. that his input was just an example.

Yeah, I read it wrong. I thought he wanted to remove everything after the decimal. Sorry for the confusion.

You may use strTmp.TrimRight(_T("0")); to the purpose.

strTmp.TrimRight(_T("0")); works as long as I have numbers after the decimal, but if I don't, it leaves me with whole numbers that end with a decimal, i.e:
610.00000
would become: 610.
However, strTmp.TrimRight(_T(".0")); seems to work! Thank you much!

Please tell me how to use the functions present in a DLL file in a new WIN32 console application.
I want to use a function from an existing DLL file, in a new program.
Thanks.

On Visual Studio, usually you have to:
(1) include the library header file
(2) add the library .lib file to you project.
(3) make the IDE know about the folder path of your library .lib file.

There is a dialog and it has more than one controls.I want to get all these controls to set or change some their properties at runtime. To do this , i use that code.
<br />
CWnd* pChildWnd = wnd->GetWindow(GW_CHILD);<br />
<br />
while ( pChildWnd )<br />
{<br />
pChildWnd = pChildWnd->GetWindow(GW_HWNDNEXT);<br />
} <br />
But i can't get controls and this while loop enters infinite loop. Please help me to get all controls. Thanks.

Can't you use EnumChildWindows()?

Hi Experts,
I have written a shell context menu COM dll. It is working fine on all files and folders. But this is not coming on briefcase. How can I achieve that.
|
|
|
|
|
I would suspect that the briefcase is not a real directory, but a namespace extension (like the recycle bin). In which case, you might be out of luck.
For this sort of thing, I use regmon from sysinternals. Navigate to the "directory", start regmon going, and see what COM reads explorer does when you right click on a briefcase item. It may not even look at the keys you have your extension registered under, which would be a hint to give up, or look if any of the keys it *does* look at give you any ideas.
Iain.
Plz sir... CPallini CPallini abuz drugz, plz plz help urgent.
