sprintf is convenient but we really ought to shun it for the reason you say. In the past I've run into nasty memory bugs in maintenance because of developers' fondness for sprintf.

Guys,
I have noticed - CHtmlView sometimes does not process correctly if form does not have submit button, Enter key does not submit.
This form will work perfectly - submit on Enter key:
<br />
<form name="myform" onSubmit="return cmd();" ><br />
<input type="text" class="form-say" name="say"><br />
<input type="submit" class="form-say" name="say" ><br />
</form>
And this one will just ignore Enter key (but in IE works fine):
<br />
<form name="myform" onSubmit="return cmd();" ><br />
<input type="text" class="form-say" name="say" ><br />
</form>
Do you know the way to work around it?
Thanks
PS - I'm using MFC with good old VC++ 6.0 . Maybe is it fixed in newer versions ?

Maybe some JavaScript that does the Submit, or a hidden Submit button, assuming that is possible.
PS. I don't thing this is a CHtmlView issue.

The problem is - I'm writing multy-window browser, so I have to process pages "as is", and this particular example - part of IRC:CGI, so I have to work with "submit-less" forms correctly.
I believe it is CHtmlView issue (not mine), because I've created simple Document/View CHtmlView-based project by wizard, and opened test "submit-less" page without any code modification - same result - it does not sumbit.

This doesn't surprise me. Why not modify the HTML after it is loaded. ie. in xxx::OnDocumentComplete().

When your dialog is created, store its class instance in a static member variable in the dialog class. Create a static function that returns that instance.
So, if your dialog class was named CDlg, then to get the dialog, you could do:
CDlg* dialog;
dialog=Dlg.GetMainDialog();

my dialog and my class are far far away...
my dlg calls a class by returning ans int to ir(this class is not a dlg)
then this class has to call another class..
this another class needs to access the dilog...
now can i pass the dlg to the class as the class is created by returning a valu..
and C++ only allows returning one param...
I HAVE TO USE RETURNING to to create the class...
so i cant substitute it with anything else

The method I showed you works as long as the other class is in the same process as the dialog class.
The other thing you can do is pass the class in the method:
Dialog calls class, passing instance of itself to the class.
Class calls class 2, passing the dialog instance that was passed to it.
Class 2 calls the dialog instance that was passed to it.

Suppose the method you wanted to call in the first class was called DoSomething(CDlg dialog), the method you wanted to call in the second class was DoSomething2(CDlg dialog), and the method to be called in the dialog was called CallDialogMethod. The code below would do what you wanted:
class1.DoSomething(this);
class2.DoSomething2(dialog);
dialog.CallDialogMethod();
You might consider buying some books on programming in C++. They'll help you with this type of thing.

Dear all
I am desperately trying to print a jpeg/bmp image in vc++.
It prints it on the top left corner of the page ina very small size.
I used the mm_loenglish mapping mode.
It would be great if you could help me to fix this.
Thankyou very much for your time.

I have an abstract base class CFoo that contains a pure virtual method void setDefault() as well as a public static method void doSomething(), like so:
class CFoo {
public:
CFoo()
{ setDefault(); }
virtual ~CFoo()
{}
virtual void setDefault() = 0;
static void doSomething() {
int x = 0;
x = 32;
}
}
One of CFoo's clients does this:
CFoo::doSomething();
which causes VC6's linker to complain that CFoo::setDefault() is not implemented. It's as if the compiler wants to construct a CFoo object (which makes no sense since it's an abstract base class).
Is it me or VC6? (It's probably me, but I can't figure out what I'm doing wrong).

I think it is VC6. Both VC7.1 and Comeau compiled it just fine.
The results I get from Comeau,
MODE:strict errors C++
"ComeauTest.c", line 7: warning: call of pure virtual function
setDefault();
^
"ComeauTest.c", line 16: warning: variable "x" was set but never used
int x = 0;
^
In strict mode, with -tused, Compile succeeded (but remember, the Comeau online compiler does not link).

Thanks.
What's weird is, I went ahead and implemented CFoo::setDefault() keeping the pure virtual specifier, and guess what - VC6 didn't complain! Eeek!  (Nor did the problem go away.)

If no one actually attempts to instantiate a CFoo object, then it won't complain.
If you just do:
CFoo fred;
it will.

Actually, you can never instantiate a CFoo, since it's an abstract class.
The problem has to do with the fact that CFoo's static (factory) method was constructing a derived class which caused the linker to want to resolve CFoo::setDefault(). This is sorta hokey, but what I was doing was wrong, since the derived class's vtable has not been initialized in the base class' constructor.

It's giving an error because you're calling CFoo::setDefault() directly, and that method is not implemented. Remember the virtual only kicks in if you call the method through a pointer. You need to call plain setDefault() to get the polymorphism that I think you are expecting.

Actually I'm calling CFoo::setDefault() indirectly - I neglected to mention that doSomething() is actually a factory method that serves up a specialization of a CFoo, which causes CFoo's constructor to be called, which causes a call to a method in a derived class, which is just plain wrong!
But I still think the compiler should have caught the error.

er, you aren't calling a virtual function in the CFoo ctor, are you? The vtbl isn't initialized yet so that will probably crash at runtime with a pure virtual function call.
