Why are you using pure C here?
As you program C++, try to use C++ structures.
Like a std::vector of std::strings.
Or the MFC-class CStringArray.
Also, input and output is much easier using the predefined IOStreams std::cin and std::cout!
Let's think the unthinkable, let's do the undoable, let's prepare to grapple with the ineffable itself, and see if we may not eff it after all.

You make the same error on each allocation:
For instance your code is
dehseth wrote: a = (char**) calloc(10, sizeof(char));
but a is declared as follows
char ** a;
hence you must allocate memory this way
a = (char**) calloc(10, sizeof(char <big>*</big>));
Please note the * operator inside sizeof.
BTW as Cedric Moonen already stated, in C++ language, new is the preferred way to allocate memory.
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

This is going on my arrogant assumptions. You may have a superb reason why I'm completely wrong.

First of all thank you everyone!
I am writing the code in DLL, and this was not the actual code. I need malloc and calloc and free in my code.
Problem solved by using * in sizeof functions. As an example:
previous code:
allocater** a = (allocater**) calloc(10, sizeof(allocater));
new code:
allocater** a = (allocater**) calloc(10, sizeof(allocater<big>*</big>));
I forgot that 50 in loop since I have tried too many things I guess.
I should have noticed this 
Thank you everybody again.
Let's keep movin'

Problem has been solved. i is the loop integer which gets values from zero to ten in given example code.

Actually, it was being incremented to 50, hence the crash and my question.

CString csSql= "update [MY_TABLE]"
" set"
" STRING_0 = \'hello\', "
" TIME_0 = \'02/30/2008 12:5:7\'"
" where"
" TABLE_ID = 10"
" and ITEM_ID = 100"
" and TIME_0 = \'01/24/2008 7:10:33\'"
;
//===============================================
When the SQL is executed, an error says:
Data type mismatch in criteral expression (3464)
//===============================================
when I delete last line of the SQL statement
" and TIME_0 = \'01/24/2008 7:10:33\'"
the SQL statement becomes OK.
type of field TIME_0 is Date/Time.
what is wrong?
any sample code for using Date/Time in 'where' of 'update ... set ...' statement?
thanks

Have you tried displaying the csSql string with a message box and verified that the SQL statement is perfect before executing it on the DB?

Max. possible day value of February 2008 is just 29 together with a leap year. Feb. 30 is an invalid date (02/30/2008).

Did you right click the control on the ToolBox?

It shows you are using VS 6.0 or lower (than 2005)
Khathar wrote: is it possible to remove that control from the toolbox? if yes how, no means why?
1) no, it is the issue with VS [PRB: Can't Remove Controls from the Controls Toolbar in VC++^], go for higher IDE like 2005 or higher it supports easy UI for that.
2) yes, but manually [How to remove a Toolbox component, an OLE Control, or a Component Gallery component from a Visual C++ project
^]
Khathar wrote: (e.g. MSFlexGrid).
remove all the files created (font1.(cpp & h) msflexgrid.(cpp & h) picture1.(cpp & h) rowcursor1.(cpp & h) remove any dependency with other classes like message handlers)
delete or backup your *.dsw file and edit your *.dsp file to remove the sections
# Section <project name> : {7BF80981-BF32-101A-8BBB-00AA00300CAB}
# 2:5:Class:CPicture

# 2:5:Class:COleFont

# 2:8:ImplFile:font1.cpp
# End Section
now re load the *dsp and allow the IDE to create fresh *dsw

Are you sure compile time is because of this, please have a look at [reducing Compilation time^]

where to add the code for status bar if i need to use it in dialog other than the main dialog,they don't have a OnInitDialog()function in them
RAJA

i did see the coding given in that link,but my question was where should i do it in the newly created dialogs,they don't have a OnInitDialog(...)....so where should i put this code
m_bar.Create(this);
m_bar.SetIndicators(indicators,2);
CRect rect;
GetClientRect(&rect);
m_bar.SetPaneInfo(0,ID_INDICATOR_NISH,
SBPS_NORMAL,rect.Width()-100);
m_bar.SetPaneInfo(1,ID_INDICATOR_TIME,SBPS_STRETCH ,0);
RepositionBars(AFX_IDW_CONTROLBAR_FIRST,AFX_IDW_CONTROLBAR_LAST,
ID_INDICATOR_TIME);

Hi,
U can only do it in the OnInitDialog(). The OnInitDialog is similar to OnCreate. So u need to place your code inside the OnInitDialog of the dialog in which u wanted place the Status bar.
thanks

I need to add the status bar in this dialog,but i don't have a onInitDialog(),so where should i add the code????????
IMPLEMENT_DYNAMIC(autoscan, CDialog)
autoscan::autoscan(CWnd* pParent )
: CDialog(autoscan::IDD, pParent)
{
}
autoscan::~autoscan()
{
}
void autoscan::DoDataExchange(CDataExchange* pDX)
{
CDialog::DoDataExchange(pDX);
}
BEGIN_MESSAGE_MAP(autoscan, CDialog)
ON_BN_CLICKED(IDOK, &autoscan::OnBnClickedOk)
ON_LBN_SELCHANGE(IDC_LIST2, &autoscan::OnLbnSelchangeList2)
END_MESSAGE_MAP()
void autoscan::OnBnClickedOk()
{
OnOK();
}
void autoscan::OnLbnSelchangeList2()
{
}

If you want to make status bar when you clicked a button you can put your code on that function,now where's problem?

OnInitDialog is an override, why don't you add this to the autoscan class.
Use can use Class View to add this override, class view -> autoscan class property->overrides: OnInitDialog.
or manually override the function
header file
class autoscan: public CDialog
{
...
public:
virtual BOOL OnInitDialog();
};
cpp file
BOOL autoscan::OnInitDialog()
{
CDialog::OnInitDialog();
// TODO: Add extra initialization here
return TRUE; // return TRUE unless you set the focus to a control
// EXCEPTION: OCX Property Pages should return FALSE
}

Hi,
I am developing an application which hooks the common dialog WIndow. I wanted to send a message to the common dialog to make a force redraw of the window. I used PostMessage API to post a message to the queue but it does not work for Child Window. How can i send a message to a child Window without using the SendMessage API.
thanks
Nitheesh

Yes SendMessage Works fine. But i want to Post Message to the Queue.

if sendmessage work, post message ought to work. try putting breakpoint in MessageHandller function to check when it recv the postmessage request
