I get the same Unhandle exception by placing it in OnInitDialog(). I think it is a different method call in net 7.1......I am wasting so much time digging for such a simple problem.....

But how are you calling the SetWindowText() in there?

I'm calling it like this
GetDlgItem(IDD_SYSTEM_ALIGN)->SetWindowText("Junk One");
|
|
|

Which is incorrect. Remove the call to GetDlgItem().

David,
It works on both ends, referencing the GetDlgItem was my problem.
Thanks a lot....

Both ends of what?

This works fine in v6. It must be something specific to v7.x, or you have other code in place that is masking the problem.

SetWindowText(...) will work i suppose.

Can someone please verify that if a derived class redefines a protected virtual function from the base class it must be redfined as a public member in the derived class. So for instance,
class Core {
protected:
virtual double grade(double) const;
};
class Grad: public Core {
public:
double grade(double) const; // OK, it's public.
protected:
double grade(double) const; // NOT OK!
};
If true, can you please provide the logic behind this? Otherwise, why is VC++ 6.0 complaining?
THANKS!! Much obliged!

It's not true. Otherwise, what would be the point of a protected virtual function if you had to make it public?
If you remove the public version from Core it should compile.
|
|

|

There is no public version in Core, only a protected version. The example shows a redefined function in Grad: one version is public and one protected. They are mutually exclusive. I only put them both there for the example.

This compiles
class Core {
protected:
virtual double grade(double) const;
};
class Grad: public Core {
protected:
double grade(double) const;
};
Nevertheless its better to keep in the declaration
virtual double grade(double) const;
cos maybe ull have another level of derivation

Thanks! I found the problem (but don't quite understand it). It's related to a clone function that I had in my derived class. When I remove the private clone function I get a clean compile. From Accelerated C++:
The return type for the clone function in class Grad must be changed to be a Core* rather than a Grad* as written in the book:
#ifdef _MSC_VER
Core* clone() const { return new Grad(*this); }
#else
Grad* clone() const { return new Grad(*this); }
#endif
because VC++ 6.0 does not yet allow a virtual function returning a pointer (or reference) to a base class to be defined in a derived class to return a pointer (or reference) to the derived type.

I have a dialog application with a list control and a edit control. I am trying to write float values to the controls, or to at least one of them, at run time. I dont know how to do this. Can someone help me out?

double d = 12.34;
char s[32];
sprintf(s, "%f", d);
edit.SetWindowText(s);
list.AddString(s);

U can use
SetWindowText for this
example
float b=.343;
CString o;
o.format("%f",b);
johnsb2->SetWindowText(o); //where johnsb2 is CEdit
Bye
Hopes this help u.

Hai guys
I have a new idea for compressing files.. it work as follows
Example:
samlpe text : "something is better than nothing"
first s is placed first letter as usual now i will find the difference between s and o and only that difference is placed and so on..
How is this idea
pls respond if u understand what i said(my language is poor .
 i know it).
bye

It seems to me its a substitution and not a compression
am i wrong?

Hum...
And how will the text compressed ???
You will need to store the difference between the two characters and this will be stored in a 1 byte type (can be more if you use integers but then you increase the size of your file !!!!).
So, you will store 1 byte instead of 1 byte. There is no compression at all and you will lose a lot of time for nothing 
|
|
|
|
|
Size of the data for string difference may be less than 1 byte.
|
|
|
|

Yes it could but to go from the lowest letter to the highest letter it will have to be as many bits as the letters anyways. You could use some type of encding to save bits for the differences using some type of average difference and making these ther shortest code but I'd bet this will not help as the differences between letters looks distributed to me.
