I think the two friend declarations need template <class T>

template <class T>

You can use const_cast, i.e.

Node * temp = const_cast<Node*>(this);

Maybe you could revise the 'constness' of the code (I did not look too closely). Perhaps read about Const correctness...

There is a contradiction, in your first post you say that "Each file has: #include "include.h"". If enum.cpp actually includes include.h, that results in the error you described.


Assuming...

Now remember the second parameter to write(), that specifies how many bytes are written.

PS. Maybe you could try to re-post your code

It seems that you are desperately trying various ways to write the file.

Maybe relax and try to master e.g. a binary .pnm file of a very small size, say 2x2 pixels hence being easily viewed in...

Read about When should my destructor be virtual? (http://www.parashift.com/c++-faq-lite/virtual-functions.html#faq-20.7)

The function prototype for ON_MESSAGE() is
afx_msg LRESULT memberFxn( WPARAM, LPARAM );


Ctry_ENTERDlg::OnBnClickedButton1 does not match, so you might add a new member function which handles...

If the stream object is in error state, then you also need to call clear() in order to make the object functional again. Could that be the reason in this case?

As soon as the map goes out of scope, its destructor takes care of destructing all the vectors, whose destructors in turn destruct all the strings. So it all happens automagically (as long as you are...

resource.h is not the place to define _WIN32_IE. Do it instead above the #includes, i.e.

#define _WIN32_IE 0x0301
#include <windows.h>
#include <commctrl.h>


Or alternatively in the...

In your project, #define _WIN32_IE to at least 0x0300.

InitCommonControlsEx() takes a pointer to a INITCOMMONCONTROLSEX struct. You are not using the function correctly ...

A typo has slipped in ... it should be localVariable.

Seems that I misunderstood the problem. Anyhow, the CMyEdit class' code that you have should capture the Enter key.
Maybe you don't have the following in the dialog class implementation
...

That functionality can be achieved by simply making sure that:

the first button (only) has the 'default button' -option checked
the first edit box does not have the 'want return' -option...

See GetExitCodeThread() (http://msdn.microsoft.com/en-us/library/ms683190(VS.85).aspx)

Don't allocate using the operator new, use _aligned_malloc() instead to have the data properly aligned.

One approach would be to

generate a default MFC-based add-in


study it so that you understand how things work


strip off all MFC/AFX -based stuff, converting the add-in to a standard DLL...

To get 'non-destructive writes', open the file specifying also the ios::in mode.

It appears as if you might have stumbled upon the virtualization feature of Windows Vista. Try looking it up on the MSDN.

You can circumvent that by ...

int main()
{
...
switch(option)
{
case 'h':
case 'H':
{ // new scope begins here ...

Wouldn't it be easiest to add 'standard' ON_UPDATE_COMMAND_UI handlers for those two sub-menus, i.e. you'd have something along the lines of:

ON_UPDATE_COMMAND_UI(IDM_SUBMENU1, OnUpdateSubmenu1)...

Hmm, you have to understand that char editControl_Content[2]; allocates space for two chars.
The array indexes start from zero, meaning that the only indexes you are allowed to access in this case...

You are not getting the window text properly, it should be


char editControl_Content[2];
// the following gets one char into editControl_Content[0] and sets
// editControl_Content[1] to '\0'...

Well, by doing the following ...


...
background = load_image("background.bmp");

if(background == NULL)
{
// load_image() failed ...
cout << "load_image() failed, error: " <<...

Assuming that SDL is unable to load the image, you might place a call to SDL_GetError() (http://sdl.beuc.net/sdl.wiki/SDL_GetError) immediately after the line:
background =...

Try with these changes

I think you are using a 32-bit toolset (VS Express) and trying to link with the 64-bit version of libmysql.lib.
The 32-bit version of libmysql.lib comes with those missing symbols, what you have is...

Perhaps your intention was to replace also a '\v' with a space but you forgot to do it?

Which compiler/OS are you using?
The (modified) code worked for me (Visual Studio 2005), but NOT with GCC 3.4.2.

A couple of things

1) When opening the file, in addition to the ios::out|ios::in flags, specify one of: app, ate or trunc (http://www.cplusplus.com/reference/iostream/fstream/open.html) flag.
...

One fix to the reading problem is to re-open the file, or alternatively you might implement
something similar to seekg() (http://www.cplusplus.com/reference/iostream/istream/seekg.html) to set...

I think you are after ...

typedef List<String^> Vec1;
typedef List<Vec1^> Vec2;

Vec2 List1;

for( int j = 0; j < 1000; j++ )
{
List1.Add(gcnew Vec1());

Use #include <time.h>, and use clock_t and clock() instead of std::clock_t and std::clock().

Hmm, just a thought .. how about changing one line of the signature to:

cout << "Hi there!" << "I'm a non-standard-compliant C++ coder!";


;)

It appears as if you might find already deleted students, because of the ...

for (int n = 0; n < MAX_STUDENTS; n++)
{
if (strcmp(delStudent, students[n].ID) == 0)
{

I think you'd want to have the string and the newline the other way around, i.e.

text += Dummy2 + System::Environment::NewLine;

Simply put, it invalidates the view so that its OnDraw() function gets called.

By the way, the OnDraw() leaks memory since you are not deleting the CRect that you allocate there.

I'm not quite sure what you actually expect to happen, but I think you maybe want to add the RDW_INVALIDATE flag to the RedrawWindow() call.

If it is TRUE, then it worked, else not (i.e. it is FALSE).

MFC provides the VERIFY() macro, which you might find useful, i.e.

VERIFY(button1.Create(_T("HI"), WS_CHILD | WS_VISIBLE |...

You are not checking the return value of Create(...), so you are unaware of the error.

Override the view's OnInitialUpdate() method and create the button there. At that point the view is readily...
