There are a few articles there and on MSDN to get you going. What's your problem specifically?

Dear all
in C language we can create dynamic multi dimentional arrays by using malloc operator.
But how we can create multidimentional arrays by using new operator in C++.
Please note that length of each dimention is dynamic and is not apparant in compile time.

You can do that in C++.

A code example for a two dimensional array:
int** pArray;
pArray = new int*[10];
for (int i=0; i<10; i++)
pArray[i] = new int[10];
This will create a 10 X 10 array.
|
|
|
|
|
For instance:
int ** p;
int n=3;
int m=4;
p = new int *[n];
p[0]= new int [5];
p[1] = new int [m];
p[2] = new int [10];
p[0][1]=13;

Not a daunting task.
Please make, at least an attempt, then post specific questions whenever you find yoursef in troubles.

There is. To complete class defintion, semicolon must be there.
So class CMyClass {} is not valid statement, its valid when you give semicolon.

I am well aware of that fact, I was trying to say that I did put a semicolon after the class definition.
But I include this file shlobj.h and then I receive the error, when I comment this file out the project builds successfully.
Why is this ???
Many Thanks.

The following codes are doing things ok. but when i try to right click on task bar button( applications task bar button - close/minimize application from system menu) minimize and close button is not repinted as expected. The codes are

ModifyStyle(NULL,WS_SYSMENU|WS_MINIMIZEBOX);
Default();
ReDrawCaptionBar( &dc );
ReleaseDC( &dc );
}

{
OnNcPaint();
return TRUE;
}

rcCap = rc;
rcCap.bottom = ::GetSystemMetrics( SM_CYCAPTION ) +

if you want to compare two images a way is that isnt very good you can use of CImage class you make two loops for height and width and use of GetPixel for check color of pixel on each images but this way is a problem and its slow but I think on the codeproject is other ways.

Hi,
Can you help me how to "synchronize" .NET DateTime.Tick and C++ time (CTime, LPSYSTEMTIME, t_time doesn't matter which one) .

Hi
I am trying the change the default font of the menu.
I have used code from http://www.codeproject.com/menu/menuch.asp.
In the App file,there are AppendMenu(),DrawItem() overriden functions.
Under drawItem(),I have written the code to change the default
font of the Menu.I have declared objects like m_FileMenu, m_EditMenu
of type App class in the Mainframe header file and through these variables
I have called AppendMenu() from within the constructor of Mainframe class.
Like m_FileMenu.CreatePopupMenu();
m_FileMenu.AppendMenu(MF_ENABLED,ID_MYFILE_NEW,"&New\tCtrl+N");
m_FileMenu.AppendMenu(MF_ENABLED,ID_FILE_OPEN,"&Open\tCtrl+O");
Similarly, I have called AppendMenu()for m_EditMenu object also.
Next,Under CreateMenu()which has been called from OnCreate handler,I have
taken the pointer of CMenu through GetMenu(), and all the default items of
menu have been removed through RemoveMenu().
Like pMenu->RemoveMenu(0,MF_BYPOSITION);
Then,through that CMenu pointer,I have called InsertMenu() through which all
the appended items are getting inserted in the menu.
Like
pMenu->InsertMenu(0,MF_BYPOSITION|MF_POPUP,
(UINT)m_FileMenu.m_hMenu,"&File");
pMenu->InsertMenu(1,MF_BYPOSITION|MF_POPUP,
(UINT)m_EditMenu.m_hMenu,"&Edit");
Now,the problem is that although the font of all the submenu items are getting changed as per my given font in the drawitem(), but the font of menu items like "File" and "Edit" are not getting changed.
If possible Can you please tell me what could be the reason behind it and what should I do to solve it?
