hi i just began with visual c++ and i had programmed in just c++
and there the code was
ofstream output ( c:.....);
output >> int y
but i tried that in visual c++but it didnt work....
This is my code:
void CBr4turboDlg::OnOK()
{
// TODO: Add extra validation here
AfxMessageBox ( "F*** you");
CString szEdit;
m_editText.GetWindowText ( szEdit );
}
I have a member variable in my edit field and i want that 2 write 2 a text file??

|

so what's your problem ???  
what error does the compiler returns (you said it didn't work...)
please be more explicit, otherwise, you'll stay alone with your empty text file...

I have searched every page for a code for writing a variable in a text file

Emm that was me above

If you write non-Unicode application, you should use simple
ofstream << (LPCTSTR)strName
With Unicode, it's more complicated, because STL doesn't provide generic text mapping, i.e. TCHAR's, LPCTSTR's etc. You could use your own mapping:
<br />
#if defined(_UNICODE)<br />
#define tstring wstring<br />
#define tofstream wofstream<br />
....<br />
#else<br />
#define tstring string<br />
#define tofstream ofstream<br />
#endif<br />
I use it in many of my apps and it works ok.

Hi every body!
I have created a global hook function (in Dll) to capture Keyboard events. Every a key has been pressed, the hook function send a user-defined message to my application. My problem is:
My application can only receive the message, when it has focus.
Could you tell me why? And How can I correct it?
Thanks!
//Hook function
static LRESULT CALLBACK KeyboardHook(UINT nCode, WPARAM wParam, LPARAM lParam)
{
if( (nCode >=0) && (nCode == HC_ACTION) && (wParam == VK_SNAPSHOT))
PostMessage(hWndReceiver, UWM_CAPTURED,0,0);
return CallNextHookEx(hookKeyBoard,nCode,wParam,lParam);
}
//Message Map
BEGIN_MESSAGE_MAP(CTestHook, CDialog)
ON_REGISTERED_MESSAGE(UWM_CAPTURED,OnCapture)
//{{AFX_MSG_MAP(CTestDllDlg)
ON_WM_SYSCOMMAND()
ON_WM_PAINT()
ON_WM_QUERYDRAGICON()
//}}AFX_MSG_MAP
END_MESSAGE_MAP()
//
afx_msg bool OnCapture(WPARAM wParam, LPARAM lParam);

Does that imply that the PostMessage() statement is posting the message regardless of what window has the focus? If not, I'd be curious if any of the three conditions preceding the PostMessage() statement are evaluating to FALSE.

I am using PreCreateWindow in my MDI application and
have noticed that it gets called twice. The first time it gets called, the CREATESTRUCT has nothing in it (e.g. lpszName is null and so are lpszClass). The 2nd time it is called, I see information of my app in the lpszName and lpszClass fields of the CREATESTRUCT. Why is this being called twice (and with one call passing nothing to it?)?
|
|
|
|
|
this is the text from the msdn
The default implementation of this function checks for
a NULL window class name and substitutes an appropriate
default. Override this member function to modify the
CREATESTRUCT structure before the window is created.
and also
By design, these derivations of PreCreateWindow are
not documented
so you too need to check for null and perform any relavant operation.
May be the first call is for you too fill any information i.e if you want to create your own window class, coz if you dont MFC defines it.
then in the next call you are given an option to modify the window style.
Still Alive!!!
Thank you God.

Can we overload the function operator () - Curly brackets ?
If yes then what would be the syntax for this.
|
|
|
|

int operator()(int i1, int i2)
{
return ;
}

Why would you want the curly brackets to have a dual role in life? What problem are you trying to solve?

I agree with you, no need to overload curly brackets.

humm???
I lookedup in MSDN and it should be links for JScript..
As far as my knowldge Brase brackets are not operators so you cant overload it.
brase brackets is used by the compiler for scope management of the identifiers.

Thank you God.

STL uses it all the time: they are called 'functors'. Search MSDN or Google for functors and you'll understand what I mean.

Right:
You can overload normal parenthesis, being (), which is what I think the original poster really meant.
You can't overload curly braces {}, because it's meaningless (although I could see some possible uses for lambda constructs, perhaps.)

No I mean for parenthesis ().
This has been asked to me during an interview. Can we overload function operator () ? If yes then how and in what scenario this would be required.

class multiplier
{
public:
int operator()(int i) { return i * 3; }
};
multiplier mul;
cout << mul(10);
