Hi all,

I'm a newbie.
I tried this visual c++ code:

Console::WriteLine("Insert a double");
String __gc * letto = Console::ReadLine();
double doppio=letto->ToDouble(0);
Console::WriteLine( "you entered " );
Console::WriteLine(doppio);

but if i enter, for example, 20.5, the last command prints 205.

What should i do to print the correct value ?
Thanx in advance,
Desmo16.

You are doing it in the correct manner .No problem with that.

Somethings seem HARD to do, until we know how to do them.

Maybe you should enter 20,5 with comma?

You are supposed to post Managed C++ questions under (Managed)C++/cli section. Going forward Please do that.

There is nothing wrong in the code. Its works fine for even decimals. Make sure u entered the decimal also while entering the data.

how to implement global subclassing

i have got around 6 controls in a Dlg and to create a subclass for all controls will be cumbersome what to do

Can you be more specific on what you really want to do, if you want to avoid Subclassing. What's your need?

what i wanted to explain is that i have got a dialog which has 6 edit controls. all controls need subclassing, so can i make one subclass and use it for all the controls. Smile | :)

I got that from your very first post that you need to subclass the controls on your dialog. Can you be specific on what type of controls are you having on the dialog that need to be subclassed and for what?
If you want to process some messages to the control's you can subclass the edit control for once.
Say create a class called CXEdit derived from CEdit and then make the control variables for edit boxes of type CXEdit

Somethings seem HARD to do, until we know how to do them.

they are all edit boxes and i need to restrict the alphabets and numbers in edit box .i cant use the PreTranslateMessage since i need to enable a listbox when i press the key .if i use subclasses it will take 6 subclasses .so can i use global subclassing and how to implement it. Big Grin | :-D

Just derive the one class from CEdit and use that class for all the controls of type CEdit .. Smile | :)

class CEditEx:public CEdit<br />
{<br />
   add extra methods or override the methods of the control.<br />
}

use the class as how we use Normal variables.
CEditEx m_Name,m_Goal;

Hi,
See CEdit::SetPasswordChar(TCHAR ch) to set the password for Edit Box.

Add a control variableto Edit-Box let m_edit.
Add following statement in your code
m_edit.SetPasswordChar('*');

Best Regards,
Aniket

Right Click on the Edit control and Select Properties and tehre you can set the Password = true in VS2003 and in VS 6.0 check the Password property from Styles Tab.

Maybe you should try this?

HBRUSH CAdmin::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor) 
{
    HBRUSH hbr;
    if(nCtlColor == CTLCOLOR_STATIC )
    {
        hbr=CreateSolidBrush(RGB(0,100,0));
        pDC->SetBkColor(RGB(0,100,0));
        //for text colour, also use this: pDC->SetTextColor(RGB(0,0,0));
    }
    else
    {
        hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
    }
    return hbr;
}
