Do you know how I can filter them out? I am working on a custom font thingie [.NET] but this font problem is annoying me.
These 5 fonts dont render at all [they just show up in some random font and MeasureItem totally fails on them.

I get them rendered correctly in .NET in my balloon help. Even Nnamdi gets that correct in his Font combo.

Huh? They show up in the actualy indian font?
I am using Graphics.DrawString and it shows up as Arial but bigger, really bigger

Actually no. He is not chking for font height. Thus they dont expand, that's all. Even in his thing they show up as Arial.
p.s. How did you see that? You are on sonork too?

I thought that you were not able to measure the height.
Anyway looks like GDI+ doesnot have anymeans to do that. You can use PInvoke to find whether a font i strue type or not.

You mean use EnumFonts and the callback etc... ?
Damn! All that work just to figure out whether a font is true type!!!
This .NET thingie is sure incomplete!!!

I don't know much about fonts, but it sounds to me like either they aren't installed correctly, or you're trying to use characters that don't exist for that font (i.e. english characters for indian fonts). Try using the Character Map utility to determine which characters are actually implemented, and then use those.

To get a string out of the value field from a simple Acccess data base I have seen the following:
strContent = (char *) (_bstr_t) db.m_pRecordset->Fields->GetItem ("Color")->Value;
What if the value stored in there is an integer?
Would it be:
strContent = (int*) (_bstr_t) db.m_pRecordset->Fields->GetItem ("Color")->Value;
I am not familiar with _bstr_t so am not sure. Another thing I saw was Value.lVal, Value.bstrVal, etc but dont recall where I saw it and what its use is specifically.
Thanks for helping,
ns

I don't see why you need char *, _bstr_t should provide that for you automatically. A _bstr_t wraps a BSTR and a char *.
nss wrote:

Nope. Replace both casts with one to int. Of course your variable needs to be an int and not a char *. The reason it's a char * is that a char * is how strings are represented in C. A char is one character.

The .vt value of the returned variant will tell you what type the returned field is. This will indicate how you treat the _variant_t data type.
The various data type can be found in the documentation of the VARIANT data type.
Here is a simple extract of how I tend to use the returned variant value from a recordset:
CString str = _T("");
_variant_t vtFld;
vtFld = pRecordset->Fields->GetItem(lpczFieldName)->Value;
switch(vtFld.vt)
{
case VT_BSTR:
str = vtFld.bstrVal;
break;
case VT_I4:
str = IntToStr(vtFld.iVal);
break;
case VT_DATE:
{
COleDateTime dt(vtFld);
szValue = dt.Format(_T("%Y-%m-%d %H:%M:%S"));
}
break;
case VT_EMPTY:
case VT_NULL:
break;
default:
szValue.Empty();
return FALSE;
}

I have a CString array a[10], that I created with new. Now I want to copy this into another array
so do I create that with new as well, and do a loop like this?
CString *b = new CString [10];
for (int i =0, i < 10, i++)
{
b[i] = a[i];
}
Also for all the "new"s I make, I need to keep them around, so should I do the delete[] in th edestructor? What if I didnt. Is that bad?
Thanks,
ns

Yes, that's how you copy the array. Yes, you need to delete[] them all or you will leak memory. Overall, you'd be better to check out using std::vector for your array needs. I have a number of articles on CP regarding the STL, which is where vector lives.

You could also use CStringArray. It cleans up after itself.

Christian already suggested STL vectors
One thing left: What's the difference between delete[] and delete.
C++ developer, even experienced ones, often tell that in C++ pointers and arrays are the same. However, this is wrong! C/C++ does syntactically not distinguish between pointers and arrays. Semantically pointers and arrays are quite different things! And this is the reason for two versions of operator delete:
CString a[] = new CString[ 10 ];
CString b[] = new CString[ 10 ];
delete a;
delete[] b;
Because arrays and pointers share the same syntax, both a and b in the above code could be interpreted as pointer or as array. However, as I wrote above, they are not sematically the same thing:
- The first delete statement (delete a) interprets <coda>a as a pointer. It therfore destroys the object (calls the destructor) to which the pointer refers - this is a[0]. Then the buffer itself is freed. The destructors of a[1] to a[9] are not called. Because CString objects manage their own string buffer and free in the destructor, these buffers are never freed for a[1] to a[9] and cause memory leaks.
- The second delete statement (delete[] b) interprets b as an array. It first calls the destructor for every single array element and then frees the buffer.
Technically the one and only difference is that if you use operatore delete[] the destructor of each array element is called, while operator delete calls only the destructor of the first element. Therfore for object types that do not have an user defined destructor, both are semantically equivalent:
TCHAR szBuffer = new [MAX_PATH];
...
delete szBuffer;

This is purely from a design viewpoint at the moment to help me understand OOP a little better - I don't want any code, just theory please.
Let's say we have four classes: Parent, Son, Daughter and Grandchild. Now if I was to model a typical local family it would look like this:
Parent
^ ^
/ \
Son Daughter
^ ^
\ /
[Grandchild<sup>n</sup>]
There can be multiple direct offspring of Parent based on this model, and each sibling pair can have more than one grandchild. Sometimes a sibling may choose to directly adopt a Grandchild without courting one of their brothers or sisters, but the siblings will never form a threesome (us country folk do have some standards you know!)
Now let's say Parent has some common attributes and methods, e.g. Age, GetAge and SetAge. How would this look from the Grandchild's perspective? I.e. how would a Grandchild determine it's age?
I'm not sure how to approach this one. 
This isn't technically related to C++, but I figured it would be the best forum given the choices.

Is your diagram an object inheritance chart or (as I suspect) is it meant to show the "is born to" relation? They are 2 very different things.
If it's an inheritance chart and the age methods are publicly defined in Parent, objects that inherit from it will also inherit the methods. So when you do:
grandChild.getAge() the method getAge() in Parent gets called.
If the method is defined virtual, descendant classes may override it. If it's defined pure virtual, they have to override (i.e. implement) it. In this case, Parent would be an abstract base class.

It was *meant* to be an inheritance chart. Then again, I didn't pay much attention to that in class...
Ravi Bhavnani wrote:

That much I understand (wow!) but what is confusing me is say the Son and Daughter objects each provide overridden Get/SetAge methods, and the Parent object's method is called from within each to perform some common task. Now if I call Grandchild's GetAge member what gets used? Would it even work? If so, would the Parent's member get called twice?
My example of ages is getting a little confusing, so let me explain the real problem I am looking at:
In a game we have many CGameObject's:
GameObject
^ ^
/ \
Animatable Intelligent ... (there are more)
GameObject GameObject
^ ^
\ /
PlayerGameObject
GameObject provides a virtual method called Frame which is called each frame in the game to allow the object to perform any actions if required to. The GameObject.Frame method performs some basic "all objects require this" actions. The AnimatableGameObject.Frame method updates the animation status, etc. The IntelligentGameObject.Frame method evaluates the AI state of the object and calls its own methods as appropriate. The PlayerGameObject.Frame performs some calculations using user input and various other factors. Now I want PlayerGameObject.Frame to perform all of the tasks of all of the overriden (inclusing its own) and the original methods. Exactly how, if at all, would this work? Could I do something like:
PlayerGameObject::Frame()
{
AnimatableGameObject::Frame();
InteligentGameObject::Frame();
}
How would GameObject::Frame be called if both the AnimatableGameObject and InteligentGameObject overidden methods call it? Argh - my head!

It would be called twice. That probably isn't what you want. So don't call it from both.

Damn, thought so. The problem is that it must be called from both as their are other objects which in turn inherit from either AnimatableGameObject or InteligentGameObject. A thought has just struck me...
** don't all say "uh oh" at once now  **
If I add a parameter to each virtual function of the direct sibling objects (those like Son, Daughter, etc) like thus...
Frame([normal parameters...], bCallRootClass)
...then PlayerGameObject.Frame would look like this:
PlayerGameObject::Frame([normal parameters...], bCallRootClass)
{
AnimatableGameObject::Frame([normal parameters...], bCallRootClass);
InteligentGameObject::Frame([normal parameters...], bCallRootClass);
if (!bCallRootClass)
GameObject::Frame([normal parameters...], bCallRootClass);
}
And then do the same sort of thing in the AnimatableGameObject.Frame and InteligentGameObject.Frame methods.
That *should* work, no? The hierarchy would never go more than three deep, and it is only on the first sibling "stage" that mutliple inheritance would take place.
