by lattice, you mean something like a grid/2d array/spreasheet ?
I suggest you display your data using Chris Maunder's Grid Control[^], and define one new cell type that will draw itseld according to the number drawn inside it.
to define the shading, you have a number of choices, I suggest something simple using RGB values; to use shades of grey; but there is a resolution issue, depending on the range of the numbers in the cells ( between lower and upper values ) each grey shade will be used for a range of number.
int iRandomNumber; int iLowerBound = 0;
int iUpperBound = 25000;
int iShadeValue;
iShadeValue = ( iRandomNumber / iUpperBound ) * 255;
COLORREF cShadeColor = RGB( iShadeValue, iShadeValue, iShadeValue );

Here's how to make a rainbowish colours:
COLORREF Rainbow(unsigned int val)
{
enum
{
max = 255,
h = max/2
};
BYTE red;
if ( val<h )
{
red = static_cast<BYTE>(255.0*(1.0-double(val)/double(h)) + 0.5);
}
else
{
red = 0;
}
BYTE green;
if ( val<h )
{
green = static_cast<BYTE>(255*(double(val)/double(h)) + 0.5);
}
else
{
green = static_cast<BYTE>(255*(2.0-double(val)/double(h)) + 0.5);
}
BYTE blue;
if ( val<=h )
{
blue = 0;
}
else
{
blue = static_cast<BYTE>(255*(double(val)/double(h)-1.0) + 0.5);
}
return RGB(red, green, blue);
}
0->Red, 128->Green, 255->Blue and the rest fall between.

Here's code to make a better rainbow:
-------------------------------------
COLORREF Rainbow(int x)
{
enum
{
maximum = 255, // Range of x is from 0 to this value.
h1 = maximum/4,
h2 = maximum/2,
h3 = 3*maximum/4,
};
const double m = 255/h1;
BYTE red;
if ( x<=h1 )
{
red = 255;
}
else if (x>=h2)
{
red = 0;
}
else
{
red = static_cast<BYTE>(-m*x+510.0 + 0.5);
}
BYTE green;
if (x<h1)
{
green = static_cast<BYTE>(m*x + 0.5);
}
else if (x>h3)
{
green = static_cast<BYTE>(-m*x+1020.0 + 0.5);
}
else
{
green = 255;
}
BYTE blue;
if (x<=h2)
{
blue = 0;
}
else if (x>=h3)
{
blue =255;
}
else
{
blue = static_cast<BYTE>(m*x-510.0 + 0.5);
}
return RGB(red, green, blue);
}

Hi,
Thanks for your help, I got really nice rainbowish colors. But I need to get only the shadows of one color (for example: different shades of grey or red). I have tried to modify your code, unfortunatelly I could't get the right solution. Is the method proposed by you suitable to solve this problem? Thanks. DirA

Code like this should do it:
double f = double(val)/max_val;
COLORREF Shade = RGB(GetRValue(BaseColour)*f, GetGValue(BaseColour)*f, GetBValue(BaseColour)*f);
Where
- val determines the shade an in between 0 and max_val.
- BaseColour is the base colour, the colour you want shades of.

How to create an application, which open multiple instances without invoking new exe.
For example if we open different word documents, many new word application will open, but there will be only one exe running at a time.
Thanks

It is for avoiding multiple instance. I need an application, whcih can spawn many instance from same exe. In WORD, if we open many word documents, we can see many windows as orginal one, but if we go to TaskManger, ther is only one WindWord.exe...

My bad. I misread your request. Most posts want to know how to limit the instances to one.

Help! Im trying to figure out Active Directory and the C++ interface that microsoft provides. I need to return to a list box all the OUs in a domain. The application Im writing should eventually allow a user to create a new user in a domain and an OU selected from it. The problem I have is, what to do after binding to the object. Here is what I have so far........
CoInitialize(NULL);
IADsOU *pObject = NULL;
HRESULT hr;
hr = ADsOpenObject(L"LDAP://OU=yyy,DC=XXX,DC=xxxx,DC=co,DC=UK", NULL, NULL, ADS_SERVER_BIND, IID_IADs, (LPVOID*)&pObject);
if (hr == S_OK)
{
// need to get all OU's here somehow?
pObject->Release();
}
CoUninitialize();
This doesnt work though and I could really use some help with this  Our AD structure is as follows:
DC=XXX.xxxx.co.uk
--OU=yyy
----OU
------User
----OU
------User
Hope this helps.
regards,

Dear everyone;
I want to build a flash decompiler. How hard is that gonna be ??? And will it take a very long time?
Does any one know how to do that? Or at least direct me to some articles if possible.
Your views and suggestions will be very much appreciated.
Thank you

I really could not find any articles about how to make flash decompilers on google. most of what i found are commercials and products.
Well i want to build a flash decompiler for legal purposes. I am not gona sell the product or anything, i just need it as part of my research and its not my ultimate objective.
Its really weird though seing companies selling flash decompilers while you say it is illegal !!!
I need more views please

I see.
So dont you know any articles about decompiling flashes ?
thanx

The flash file format is open, you can check out from the results here:
http://www.google.co.in/search?hl=en&q=swf+file+format&meta=[^]
These should be enough for decompiling a flash file manually. But if you are looking for an article that explains how to build a flash decompiler, I am not sure but it is unlikely that you will find one. You might want to search on www.sourceforge.net to see if any open source flash decompiler is available.
thanks!

I have to play a movie using DirectX from a URL. But the IGraphBuilder interface accept only file name. Can I use a file name as URL ( i.e play movie from a webserver)

I have one result in .txt file.When the user clicks on the line then pop up window should come up so that's why I want to put my data on the MFC window.
How it could be done???

Could you be more specific ? Which window ? Which text file, which result... ?
Can't you simply read the file and put the result in an edit box or something like that ?

i have some data. that I wnat to open using the menu dialog option open. So the user can see the file on the MFC dialog window. It's the huge data file.
I want to put some links in that window so when the user clicks on the link the pop-up window should come.
Akshay

Geez, be more explicit. What is this MFC dialog window ? And how do you want to display your data ? Is it plain text ? So where do you want to display it ? In an edit control or what ?
And what are these links you are talking about ? And what is this pop-up window that comes when you click on the links ?
Akshay Sankeshwari wrote: I wnat to open using the menu dialog option open.
Anyway, this part (opening with the open from the dialog menu) needs to be done with serialization (but this won't work I think if your file wasn't saved by your program). If you want to overcome this problem, just add another entry in the menu and associated with your own function for loading the text file. Then when it is loaded, you just have to display it.

i have some text data in txt file. That thing I wnat to put on the MFC dialog window. The file get loaded when user selecte the open dialog menu clicks.
When user clicks on the line(which is a link to some other file)then one more child window will open & user can able to see the data.
That data is large so if possible then that data I want to put it on the MFC dialog window itself.
