VC++: Validate character/string in unicode(multi lingual support)

Hi All,
I need help regarding validating a string. This string is in unicode i.e it supports multiple languages.
I need an API which checks if a charater/string is supported by the current font or not.

Detail:
I need to show all the charaters supported for the selected font(from a combobox) in a grid layout. Then when user selects a particular grid, the string should get updated in a rich edit text control. Currenly I can see blank gyphs for characters which are not supported by the selected font. And same appear in the richtext control.
My requirement is to: Not to show the string in the grid control if it is blank.
Solutions tried till now:
I tried GetCharacterPlacement, MultiByteToWideChar, IsTextUnicode and GetGlyphIndices(does not work on XP).
But nothing useful.
Has anyone come across a situation like this.
Please help me. Am stuck badly.

Thanks,
Arti Gujare

use CRectTracker to track down the movement and then when you use the L button up, you have the new rectangle (held by CRectTracker) to place your dialog within.

hope this helps ya

Memory Leak

Hey
When I run my prog the size visible in the task manager goes up by about 5mb each second. I have searched for information about memory leaks but most is about remembering to delete memory set with new, malloc , etc.

My prog only uses STL and a couple of pointers to arrays... how can I see which lines of my code are causing the problem??

cheers

I suggest you use an profiler tool like the one from http://www.compuware.com/products/devpartner/[^] Good luck!

If it's an MFC program, then starting the debugger will show you in the output window the memory leaks when you close your program.

If you are using STL it might be possible that you are passing these STL arrays in a function as a paramter or returning from a function. Check out if you are using a normal copy or reference copy.
This might shoot up the memory used though not using new/malloc.

I am passing stl vectors and returning them. Some of the fuctions have reference parameters.

So basically at the end of each function I need to call vec.~vector() ??

cheers and thank you

program might consume more memory if you pass the array this way

<br />
void foo(vector<int> vArray)<br />
{<br />
// do something.<br />
}<br />
<br />
try doing<br />
void foo(const vector<int> &vArray)<br />
{<br />
// do something.<br />
}<br />
<br />
or<br />
void foo(vector<int> &vArray)<br />
{<br />
// do something.<br />
}<br />

it consumes more memory, but it doesn't leak the memory...

Please see the initial question posted
""When I run my prog the size visible in the task manager goes up by about 5mb each second. ""
This can happen without memory leaks too. using STL
Hence the guess.
Did it help?

i had read && understood his question.

what he desscribes looks really like a memory leak because if it was a huge allocation, it would happen depending on what he does thru the application, and it would certainly allocate a big memory block once, and stop then.

what you answered is not a solution to fix memory leaks, even using STL AFAIK.

it's much a good habit to use when dealing with big objects as function parameters (and not only STL containers).
and it's not because he changes his functions signatures by using references that his memory won't increase that fast... (maybe less each second at least, but that's all).
