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.

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.

I am trying to develop an application which will be able to convert several
European currencies to Euros and back, using visual C++

I need to convert 3 currencies to euros and theother way.

I also need to connecting it to a database where currency data
from at least 10 European countries will be stored.

The user must be able to choose to convert any of the
currencies included in the database, or add more currencies of his
choice, using application’s database link.

Can you help me out ?

Compiler Error C2628

Hi all,

Every time I try and compile I receive a Compiler Error C2628, stating the following:

Error 16 error C2628: 'DWORD' followed by 'unsigned' is illegal (did you forget a ';'
c:\program files\microsoft visual studio 8\vc\platformsdk\include\wtypes.h 385
Error 17 error C2628: 'DWORD' followed by 'long' is illegal (did you forget a ';'
c:\program files\microsoft visual studio 8\vc\platformsdk\include\wtypes.h 385

And when I press F1 on the error, the MSDN states the following on the problem:

Error Message
'type1' followed by 'type2' is illegal (did you forget a ';'?)

A semicolon may be missing.

The following sample generates C2628:

  Copy Code 
// C2628.cpp
class CMyClass {}
int main(){}   // C2628 error

Possible resolution:

  Copy Code 
// C2628b.cpp
class CMyClass {};
int main(){}

But as far as I can see there is no semicolon missing !!
Can someone please help me ??? Confused | :confused:

Many thanks.

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

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) . I need to write certain time to file (using .NET C# -> write Ticks value) and than read it in C++ == create time structure (constructor with !same! ticks or something...) . I'm using old VS 6 C++ !!!

thanx

Menu Font problem [modified]

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?
