Re: Hi - C / C++ / MFC Discussion Boards

Thanks

What I want is to add dual functions to it

like multiply divide on the same button or Fahrenheit To Celsius and vice versa on the same button

The one you showed displays different texts not what I want

Thanks

You seem to be contradicting yourself. "Multiply" and "Divide" are different, as are "Fahrenheit" and "Celsius."

As you can see the button have 2 hover states

What I intent to do

if the user clicked on the left half the button perform division or Fahrenheit to Celsius if the user clicked on the right half the button perform multiplication or Celcius to Fahrenheit

The button perform 2 operations depending which half you click

Which is exactly what the article I pointed you to does, although it has 8 "sides."

it just displays different text loll

i want the button to perform 2 actions

Are you that inept that you cannot figure out that if the code is currently figuring out which one of eight sides of a button is being clicked and performing a single action (e.g., updating a listbox), it could easily be changed to perform eight separate actions instead? Roll eyes | :rolleyes:

I want code snippets to add!#?

i need the the code to add

it is complicated

it uses user definded messeges etc !~

Only because you're making it that way.

And what is that supposed to mean? Are we not going to be able to read your code as a result? I provided you with code that does 90%, if not more, of what you require. Just how hard is it to come up with the balance?

Hi
Can you provide with code needed for it

Reflected message etc user defined message etc

any code necessary and needed to make it work??

It's all right here.

As a programmer, that's your job.

Hi
Ty

I,am new can you add the code to http://www.4shared.com/file/105379147/23d04050/dualactionmfcbutton.html[^]

plz

No I can't. Good luck.

helo

Here is the code i made it did not work loll

Sorry

It compiled but it did not work loll

Here is the code i wrote in

void C_Double_Task::OnClicked()
{

DWORD dwpos = GetMessagePos() ;
CPoint pt ;
pt.x = LOWORD(dwpos );
pt.y = HIWORD(dwpos) ;
CRect client_rectangle ;
GetClientRect( client_rectangle) ;
CString strA , strB ;
double db_a ,db_b ;
GetParent()->GetDlgItemText(IDC_NUM1,strA) ;
GetParent()->GetDlgItemText(IDC_NUM2,strB) ;
db_a = atof(strA);
db_b= atof(strB);
double result ;

result = db_b + db_a ;
CRect leftRect ;
leftRect = client_rectangle ;

leftRect.right = client_rectangle .left +client_rectangle.Width()/2;

if(leftRect.PtInRect(pt))
result = db_b - db_a ;

CString Str_result ;
Str_result.Format("%3.2f",result);

GetParent()->SendMessage(UDM_REGION_CLICKED, result);

}

Wink | ;)

and

LRESULT CHashiDlg::OnRegionClicked( WPARAM wParam, LPARAM lparan12 )
{
CString resl ;

resl.Format("%3.3",wParam);

SetDlgItemText( IDC_RESULT , resl) ;

return (0);
} Wink | ;)

What doesn't work? Does OnClicked() get called? Does OnRegionClicked() receive the message? Is the value of result correct? What does wParam contain?

[edit]
I just made a few changes to that article I pointed you to and it worked fine.

Hi
I made this on OnClicked ( the derived custom button)

void C_Double_Task::OnClicked()
{

DWORD dwpos = GetMessagePos() ;
CPoint pt ;
pt.x = LOWORD(dwpos );
pt.y = HIWORD(dwpos) ;
CRect client_rectangle ;
GetClientRect( client_rectangle) ;
CRect leftRect ;
leftRect = client_rectangle ;

leftRect.right = client_rectangle .left +client_rectangle.Width()/2;
IsRight = TRUE ;
if(leftRect.PtInRect(pt))

IsRight = FALSE ;

GetParent()->SendMessage(UDM_REGION_CLICKED, 12);

}

all what do is to set flag if on the right half or left half

LRESULT CHashiDlg::OnRegionClicked( WPARAM wParam, LPARAM lparan12 )
{
UpdateData();

double num1 , num2 , result ;
num1 = atof(m_strNum1);
num2 = atof( m_strNum2);

result = num1 + num2 ;
if (m_two_actions_botn.OnRight() )
result = num1 - num2 ;

m_str_Result.Format("%3.2" ,result);

UpdateData(FALSE);
return (0);

The OnRegionClicked check the flag throught fubction onRight and perform addition or subtraction depending on the value of IsRight ''

it also did not succeed loll

Did you even bother to read and understand the code in the article I pointed you to 10 days ago? The changes I made to it (to have a two-sided button rather than an eight-sided button) took no more than three minutes.

Hi there guys!

I wrote a BigNum class with two operations (addition and subtraction) and it consists of an array of integers. But lets suppose I read two numbers, with the following digit separation:

120 43 353 54 345
54 345 455 34 344

This is in base ten. Adding them together I get:

174 388 808 88 689

Which, obviously, is wrong. I used the standard addition algorithm, and it seems correct, so my question is: after "manipulating" the values, how can I print them correctly in base 10? Or do I need to keep a byte string with the digits and start from there?

Best regards

Fratelli

How you will read big num & fill it in array of int?

Your "digit separation" does not make sense to me.
Looks like you forgot the carry (even though you say you used the standard addition algorithm)
Converting to base 10 is easy, but not trivial (you can not convert every integer to base 10 and then concat them, I hope you didn't even think of that as a possibility)

Is it normal to have some groups of 2 and others of 3?

You digit separation doesn't make sense. Do your operations make sense, instead?
