Here is a way to do it
Class YourClass
{
public:
void operator=(const &YourClass c);
private:
int iNum;
CString szStr;
}
void YourClass::operator=(const &YourClass c)
{
iNum = c.iNum;
szStr = c.szStr;
}

Excellent example of an assignment operator overload. Unfortunately this was not what the OP wanted, he asked for a equality operator overload!

opps 
about equality,your code looks ok...so there shouldn't be any problem

Your operator is correct !

Wow, got it right on the first guess. Thanks for the confirmation.

hi,
I have some tbbuttons with text only on my toolbar.
The code looks like
<br />
for(int s = 0 ; s < groups.size() ; s++){<br />
if (groups.at(s).IsVisible()){<br />
tbb[m].iBitmap = I_IMAGENONE;<br />
tbb[m].iString = m_wndToolBar1.GetToolBarCtrl().AddStrings(groups.at(s).GetGroupName());<br />
tbb[m].fsState = (m==0)?TBSTATE_CHECKED:0 |TBSTATE_ENABLED;<br />
tbb[m].fsStyle = BTNS_BUTTON|BTNS_CHECKGROUP|BTNS_SHOWTEXT;<br />
tbb[m].idCommand = IDM_FIRST_OPENGROUP + groups.at(s).GetGroupId();<br />
m++;<br />
}<br />
}<br />
m_wndToolBar1.GetToolBarCtrl().AddButtons(m, tbb);
<br />
m_wndToolBar1.GetToolBarCtrl().SetButtonSize(CSize(95,35));<br />
THIS last line i have to add so the text will be on my buttons. If i don't change the button size then the text is completely of the button (except for 1 pixel).
SO after changing, my button is 35 pixels high, but the text is completely on the bottom half of the button. 
I just want to have small buttons (let's say standard size (22pixels)) but then my text isn't readable. How can i solve this?
greets,

I'm getting a C1001 error (internal compiler error) with the following console app:
#include <windows.h>
class blah {
public:
blah();
~blah();
} ;
blah::blah()
{
}
blah::~blah
{
}
int main( void )
{
return 0;
}
I know exactly where the error is (I somehow managed to forget the "()" after "blah::~blah"), but is anyone else seeing this compiler error on VC6 w/SP6? It took me long enough to find the true error...

Like most things, unless data integrity is involved, it'll likely not get fixed. For a product that is roughly six years old, it does not make sense to make changes to it simply for the sake of making changes.

hello,
i have a problem i have been trying to solve for the last two weeks but i haven't even come close to finding a solution.
In my SDI app, i open a dialog through the document class by obtaining the view and opening the dialog:
<br />
POSITION pos = GetFirstViewPosition();<br />
G5GravFormVW * view = (G5GravFormVW *)GetNextView(pos);<br />
...<br />
m_gravureDlg.Create(view);<br />
m_gravureDlg.ShowWindow(SW_SHOW);<br />
m_gravureDlg.UpdateWindow();<br />
i then need to update the controls on this window through callback functions so i use:
<br />
if (AfxGetMainWnd()->GetForegroundWindow() != NULL)<br />
AfxGetMainWnd()->GetForegroundWindow()->SetDlgItemText(1033, "Ajout du fichier: '" + CString(object->GetFileName()) + "'...");<br />
if (AfxGetMainWnd()->GetForegroundWindow() != NULL)<br />
AfxGetMainWnd()->GetForegroundWindow()->UpdateWindow();<br />
It has been working fine for Windows 98, NT and 2000 but now with window XP, there's a problem: when i open another application (let's take for example Windows Explorer) on top of my app and then close or minimize the new app window to come back to my app's window, the window (dialog) i opened is not refreshed or redrawn anymore whereas it was before using Win XP. so it's impossible to follow the progress of my app!
i tried all the Window State and Update/Painting Functions, SetForegroundWindow (), Invalidate (), BeginModalState (), etc... but nothing is working.
thanks for ur help

Hola!
I´m making a small Windows Forms App. using VC++.net 2003.
Adding a "MessageBox" in the self generated code (the Form1.h - file) works fine, until I add my own header file to the project and include this new header file at the top of the "Form1.h" -file.
I get the error message:
error C2653:"MessageBoxA" is not a class or a namespace name.
Why this "MessageBoxA"?
What could be wrong?
thanks

Are you adding your own MessageBox() function, or are you calling MessageBox()? If the latter, why do this in a .H file?

I´m callin MessageBox : MessageBox::Show("string");
I´m doing it in the self generated code simply because double-clicking e.g. an Button in the design mode, the method that handles this is placed in the Form1.h file automatically.
Don´t really need to have it there. Just trying to learn the basics now...

MessageBoxA is the ANSI version of MessageBox (MessageBox is actually a macro that expands to MessageBoxA in ANSI builds and MessageBoxW in UNICODE builds). Apparently the compiler can't see the definition of MessageBoxA at the point of error. Perhaps you didn't include the correct header files in the correct order, or you may have unmatched #ifdef/#endif statements. Since it happens when you include your own header file I'd look in that for unmatched statements.
Disclaimer: I have never worked in VC++.net 2003, but the above applies to VC++ 6.0.
Cheers

I've got these structs
struct node
{
string label;
node *next;
};
struct titleNode : public node
{
node *child;
};
template<typename typeOfData>
struct dataNode : public node
{
typeOfData *data;
};
I want to be able to traverse through something that might look like this:
title-title
|
node-title-node
|
node
An example function:
void traverse(node *start)
{
node *current = start;
while (current)
{
cout << current->data << endl;
current = current->next;
}
}
The line at PROBLEM1 won't work since data isn't a member of node. The line at PROBLEM2 works fine BUT I won't be able to reach any of a titleNode's children of the same reason as PROBLEM1. So the question is: How do I now what to cast to? Can you find this out some way, I mean there actually IS a full titleNode with a child under start even if you can't see it through the start pointer?

I would put everything in one node class:
<br />
struct node<br />
{ <br />
string label; <br />
node *next;<br />
node *child;<br />
};<br />
<br />
template<typename typeOfData>struct dataNode : public node<br />
{ <br />
typeOfData *data;<br />
}<br />
<br />
void traverse(node *start)<br />
{<br />
node* current=start;<br />
while (current) <br />
{<br />
cout << (static_cast<dataNode<int> >)->*data < endl
if (child) traverse(child);<br />
current = next;<br />
}<br />
}<br />
This uses recursion, but it's just an example. I would use child == NULL as an indication that it's a "node" node and child != NULL as proof that it's a "title" node. But you can also implement type information (e.g. by an enum) as a member variable in the struct.
In any event, you still have a problem with identifying what kind of data data points to, here you also need some sort of type information analogous to the node-type problem.

Yeah, maybe that's the best solution... Thanks!

Use dynamic_cast for your casting. It will return NULL if the cast can not be done.
void traverse(node *start)
{
titleNode *currenttitle = dynamic_cast<titleNode *>(start);
if (titleNode)
{
}
else
{
dataNode *currentData = dynamic_cast<dataNode *>(start);
if (dataNode)
{
}
else
{
}
}
}

hmm, that solution seems nice, but the compiler gives me a C2683: "'node' is not a polymorphic type"
|
|
|
|

Ok, a polymorphic type is a class or struct that has virtual functions. The easiest way to make your node struct polymorhic is to add a virtual destructor
struct node
{
string label;
node *next;
virtual ~node() {};
};You will also have to enable RTTI (run time type information) by setting the /GR compiler option (may already be done).
