Then you should use:
ofstream file("c:\\test.txt", ios::binary);

thanks for the answer but i dont want to use ofstream and ifstream class instead i want to use fstream class only. Is it possible? and i also need the file to be created as using ofstream.

|

if the file does not exist, you have to use
fstream file("c:\\test.txt", ios::out | ios::binary);

what's problem with this bit masking
ios::in | ios::out | ios::binary
since we have specified out in the mask, why the file is not being created.
thanks for replying.
|
|
|
|

The problem is you can't read from a not exitsting file, I suppose.
Your bit mask works if the file do exist. On the other hand, if the file does not exist you should use the
ios::out | ios::binary
mask.

Hi,
I am using ON_WM_KEYDOWN event for keyboard shortcuts in my application. And below is function to handle this keydown action.
void CRearPanel::OnKeyDown(UINT nChar, UINT nRepCnt, UINT nFlags)
{
if(nChar == 112)
{
if(((CMainFrame*)AfxGetMainWnd())->GetRearPanel()->m_hWnd != NULL)
((CMainFrame*)AfxGetMainWnd())->GetRearPanel()->ShowWindow(SW_HIDE);
if(((CMainFrame*)AfxGetMainWnd())->GetHWSimulatorDlg()->m_hWnd != NULL)
((CMainFrame*)AfxGetMainWnd())->GetHWSimulatorDlg()->ShowWindow(SW_HIDE);
}
else if(nChar == 113)
{
((CMainFrame*)AfxGetMainWnd())->OnViewHWSimulator();
if(((CMainFrame*)AfxGetMainWnd())->GetRearPanel()->m_hWnd != NULL)
((CMainFrame*)AfxGetMainWnd())->GetRearPanel()->ShowWindow(SW_HIDE);
}
else if(nChar == 114)
{
((CMainFrame*)AfxGetMainWnd())->OnViewRearpanel();
::SetFocus(((CMainFrame*)AfxGetMainWnd())->GetRearPanel()->m_hWnd);
if(((CMainFrame*)AfxGetMainWnd())->GetHWSimulatorDlg()->m_hWnd != NULL)
((CMainFrame*)AfxGetMainWnd())->GetHWSimulatorDlg()->ShowWindow(SW_HIDE);
}
CDialog::OnKeyDown(nChar, nRepCnt, nFlags);
}
Now let me explain my problem,
Here I am having one main document window which is coming up initially. And I have another 2 dialog window which should be open on keydown event. From main document window I am able to get key down event and functionality working properly. In Those 2 dialog I put same events, and there start my problem. First time when it(dialog) comes up its not catching keydown event. If I close that dialog and then open it again then I am able to catch it. I found on net some where to put below code,
BOOL CRearPanel::PreTranslateMessage(MSG* pMsg)
{
if( pMsg->message == WM_KEYDOWN )
{
::TranslateMessage(pMsg);
::DispatchMessage(pMsg);
return (1);
}
return CDialog::PreTranslateMessage(pMsg);
}
But I dint find it helpful. Can any one help me for this issue.

Do you want the dialogs to execute anything when key down?
or..
Is the parent window the one that has to execute anything on the key down from dialog?

So focus is not fixed sometimes its that in main dialog sometimes in child dialog. Is there any way that for 3 keys F1, F2, F3 took event in mainframe or main application class. I dont want to pass this 3 key down event to any further dialog,

You were not bothering, and sorry about the absence (I was pretty busy last days).
Glad that you found a solution

why do u need for google APIs?
 Failure is Success If we learn from it!!

The Google Maps API have a lot of practical applications, not the least of which is just to learn how it works. To question someone's need for that seems silly.

Well, this is your third time doing this question, and you don't even bother in changing such a lazy content.
In one [^] of them you got an answer from Christian Graus and, in the second one[^], you got an answer from me.
Instead of asking another time, why the hell don't you take a look in your previous questions?
If you continue like that, I bet that you will not end nicely.
Regards.

Judging by the questions you're asking about the PE format, you'll find this article[^] and this one[^] very useful.

how does a class allocated in memory image?
i.e.
class A{
public:
A(void);
virtual ~A(void);
public:
virtual void someMethod(void);
virtual void someMethod2(void);
public:
void someMethod3(void);
void someMethod4(void);
private:
int m_nMenber;
};
A a;
how does these virtual functions and normal functions and member data allocate in memory as part of a.
more complicate:
class B : public A{
public:
B(void);
~B(void);
public:
virtual void someMethod(void);
virtual void someMethod2(void);
public:
void subClassMethod(void);
};
B b;
how does new inherited functions and new created functions allocate in memory as part of b,which is inherited from A?
any professional help would be appreciated!

Hello
Can any body tell in detail what is relative virtual addressing and all its basics?
Why virtual addressing is needed? How RVA invlolves in execution of PE files(EXEs,DLLs and so on..)
Regards
Muhammad Usman Khalil
|
|
|
|
|
When the loader loads a DLL or EXE the address it loads it at (the base address) plus the RVA of something of interest in the image will give you its address in memory. Put another way, it's the location of something in memory relative to the base address of the containing module. Remember that DLLs can be relocated if need be so the base address need not always be the same.
