Still not getting reply from your side!!!!!!
Ok let me explore something more that what I have tried that you can understand more in this problem.
I include #include Ntsecapi.h file into my .h file (where I want to use this functions) and I try to use this function like below.but it gives me the errors as I going to show....
<br />
PULONG count;<br />
PLUID *luidptr;<br />
LsaEnumerateLogonSessions(count,luidptr);<br />
I got the errors using this function like below...
<br />
<br />
error LNK2028: unresolved token (0A000009) "extern "C" long __stdcall LsaEnumerateLogonSessions(unsigned long *,struct _LUID * *)" (?LsaEnumerateLogonSessions@@$$J18YGJPAKPAPAU_LUID@@@Z) referenced in function "public: void __clrcall CUserInfo::OnCreate(void)" (?OnCreate@CUserInfo@@$$FQ$AAMXXZ)<br />
<br />
error LNK2019: unresolved external symbol "extern "C" long __stdcall LsaEnumerateLogonSessions(unsigned long *,struct _LUID * *)" (?LsaEnumerateLogonSessions@@$$J18YGJPAKPAPAU_LUID@@@Z) referenced in function "public: void __clrcall CUserInfo::OnCreate(void)" (?OnCreate@CUserInfo@@$$FQ$AAMXXZ)<br />
<br />
fatal error LNK1120: 2 unresolved externals<br />
Plz help me. I am confused with problem.

Have you added Secur32.lib in dependencies of the project?

You missed the point (and the following 'h').
Change
#include <stdlib>
to
#include <stdlib.h>

You mean array of integers?
Then, int a[3][4];

how to create random real number matrix 3x4?thanks

I didnt get you...
You mean elements as real numbers?
If so float a[3][4];
And for getting random numebrs you can use rand(). But it is returning integer values. So you have to convert it to real. For example,
float f = ( rand() % 1000 ) / 1000;
|

NS17 wrote: float f = ( rand() % 1000 ) / 1000; // random number between 0 and 1
the above always evaluates to
float f = 0;
Moreover, the best way to produce statistically meaningful random values inside a range is (see http://msdn2.microsoft.com/en-us/library/398ax69y.aspx[^])
int u = (double)rand() / (RAND_MAX + 1) * (range_max - range_min) + range_min;

Yes. I forgot about the casting...
It has to be
float f = ( rand() % 1000 ) / 1000.0;
|
|

for instance:
const double MIN_RANGE = 3.0;
const double MAX_RANGE = 1200.0;
int i,j;
double m[3][4];
for (i=0; i<3; i++)
{
for (j=0; j<4; j++)
{
m[i][j] = (double)rand() / (RAND_MAX + 1) * (MAX_RANGE - MIN_RANGE) + MIN_RANGE;
}
}
see MSDN http://msdn2.microsoft.com/en-us/library/398ax69y.aspx[^]

why (RAND_MAX + 1) is needed?
|
|
|
|
|
const double MIN_RANGE = 3.0;
const double MAX_RANGE = 1200.0;
// change the range to fit your needs, of course keep MAX_RANGE > MIN_RANGE
int i,j;
double m[3][4];
for (i=0; i<3; i++)
{ for (j=0; j<4; j++)
{ m[i][j] = (double)rand() / (RAND_MAX + 1) * (MAX_RANGE - MIN_RANGE) + MIN_RANGE;
}
}
however i couldn't get m=3x4 matrix yet, please can give me detail..i did in IDE.
the reslut is 0013fecc..
thanks a lot

Hi,
I am mainframe programmer as such its been really difficult to make the transition to OO way of thinking anyway....
I have a table or a structure which I would like to make dynamic
meaning I can add an entry to it and just re-compile and re-build it
IS DLL export/import they way to go meaning when I define the structure add dllexport to the defination
and make the structure a DLL and get the address of the table with GetProcAddress
Thankx

1. Lets say I have a MFC SDI with a dialog containing 5 edit boxes.
2. I want to left click on any of the five edits and generate "Hello" in it.
3. I have reached the point where I can click anywhere on the dialog and generate "Hello" into one single edit box.
4. I haven't figured out how to determine if the click is in one of the edit boxes rather than anywhere in the dialog.
5. Then I need to know which edit box.
So, I need advice on #4 and #5. Here is what I have:
CTest.h
afx_msg void OnLButtonDown(UINT nFlags, CPoint point);
CTest.cpp
BEGIN_MESSAGE_MAP(CTest, CDialog)<br />
ON_WM_LBUTTONDOWN()<br />
END_MESSAGE_MAP()<br />
...<br />
void CTest::OnLButtonDown(UINT nFlags, CPoint point) <br />
{ <br />
CDialog::OnLButtonDown(nFlags, point);
GetDlgItem(IDC_EDIT_C1L1)->SetWindowText("Hello");
}
Thanks

Try as follows...
BOOL CTestDlg::PreTranslateMessage(MSG* pMsg)
{
if( pMsg->message == WM_LBUTTONDOWN )
{
if(( pMsg->hwnd == GetDlgItem( IDC_EDIT1 )->m_hWnd ) ||
( pMsg->hwnd == GetDlgItem( IDC_EDIT2 )->m_hWnd ))
{
::SetWindowText( pMsg->hwnd, "Hello" );
}
}
return CDialog::PreTranslateMessage(pMsg);
}

When you click on an edit control, the message goes to the
edit control window, not to the dialog window.
You could derive a class from CEdit and use that class to
subclass the edit controls. When your CEdit-derived class gets a
WM_LBUTTONDOWN message, it could notify its parent by posting an
app-specific message.

you may use the function sprintf function, for instance
int i;
char buffer[20];
i=7;
sprintf(buffer,"%d", i);
or, if you prefer the CString class
int i;
CString str;
i=7;
str.Format("%d", i);
