it is not created because, as soon as OnInitDialog function Exit, scope of MyStatic variable will end which inturn destory the object..
Now if you want to see Your Dynamically created Static Box you have to decalre CStatic variable as global or as classmember, so ity lifetime is that of program Smile | :)

Overloaded member function not found in CNoteMgr

Hi,
I create MFC extension DLL and wrote couple of functions adding one class i.e.CNoteMgr
in the DLL workspace.
In the class header of CNoteMgr,
there are two functions whose signature is given as below :

BOOL CNoteMgr::drawLine(HDC,HPEN,POINT,HWND);
BOOL CNoteMgr::drawCurve(HDC,POINT,HWND);

The implementation has been done in different way for line drawing and drawing curve.

But while compiling the DLL, i am getting the following errors as below :
****************************************************************************************
Compiling...
Notebook.cpp
D:\FancyViewer\Notebook\Notebook.cpp(78) : warning C4101: 'msg' : unreferenced local variable

Generating Code...
Error executing cl.exe...
****************************************************************************************
PLEASE NOTE that the error id is "C2511".

I do not know where the point of overloading comes as the method names are different.
I found from MSDN regarding the error C2511 and tried all possibilities but still
the problem persists.
=========================================================================================
MSDN says that for the error C2511
'identifier' : overloaded member function not found in 'class'
No version of the function is declared with the specified parameters.
Possible causes :

(1)Wrong parameters passed to function.
(2)Parameters passed in wrong order.
(3)Incorrect spelling of parameter names.
The following sample generates C2511:

Example ->
// C2511.cpp
class C {
int c_2;
int Func(char *, char *);
};

int C::Func(char *, char *, int i) { // C2511
// try ...
// int C::Func(char *, char *) {
return 0;
}=========================================================================================
Can anyone help me out please ??

Changed as the folowing:

<br />
BOOL CNoteMgr::drawLine(HDC,HPEN,POINT*,HWND);<br />
BOOL CNoteMgr::drawCurve(HDC,POINT*,HWND);<br />

Because of your implementation is POINT[]

Get number of days used

My app requires to update software from the internet.

I need to know the number of days from last update day to current day.

one solution is using GetSystemTime().
GetSystemTime() obtains year, month and day, but how to transfer SYSTEMTIME to absolute days, so number of days between the period can be calculated easily.

Insert Animation Control on dialog .
Add variable from it (m_AVICtrl);
add avi source to your project (IDR_AVI1);
call Open of variable :---> m_AVICtrl.Open(IDR_AVI1) ;
call Play function ---> m_AVICtrl.Play() ;

modulus operator

12-Jul-06 16:25

Hey all,
I need to do this operation

float x;
int y;
int z;

x= (float)((y-z)/60);
if(x % (int)x)!= 0)
{x = (int)x +1;
}

how do i do a mod of float and int. If x is an int then, I can use % operator. But in my case I need to find out if x = 2.1 then I need to round it to 3 ; also if x= 2.6, i need to round it to 3.

How can I do this? Can anyone help? Iam using VC++6.0

Thanks in advance.

x=ceil(x);<br />

{<br />
x = (int)x +1;<br />
}<br />

hey what happens to
ceil(x);
if x =2.0, then will it be 2.0 or 3.0?

try this

float x = 2.1;
int n= x;
if( n < x )
{
n++;
x = n;// x will contain 3 now
}
