That is the problem with the Babylonian method you have used.
Paul Hsieh has a very good webpage on everything about square roots but were afraid to ask.

It includes details most of the techniques from the standard C library, to the faster integers version that NVidia and Quake use.

hi..i have a requirement to write C/c++ application that converts Microsoft Word
(.doc) Documents into XML format. The application should be able to receive/open a Word document and save a XMl file with the same
name, but with the extension .xml..ur valuable suggestions will help me n will be appreciated..thanks
|
|
|
|
|
|
is there any library file to include in the code?..how to convert the entire docx formate?
|
|
|
|

You need to follow some of those links and do some research. As I said, reading Word documents in C/C++ is not particularly easy, unless you are familiar with C++/CLI, in which case you can use the Microsoft.Office.Interop.Word Namespace[^]

yes i have good experience in c++ but i have not worked on this requirements..if so i can read the data but question is how to store tht in xml format...suggestions will be greatly appreciated

Store what? A word document is just like a book, lots of words separated by punctuation characters. In order to store that as XML you will need to design a set of rules and tags to split the data into logical sets. Each set would probably need some attrinutes, such as font (character set, height, fixed or true-type, bold, italic etc.). Writing the final XML is just a question of using one of the XML libraries available, either Microsoft or third-party.

thank u for ur reply..can u pls provide me links it would great help

I already gave you a link to the Word Interop. You should be able to search MSDN for yourself to find other pages of interest.

I'm thinking the easiest way would be to use Office Automation.

why do we use %u while outputting addresses????
|
|
|
|
|
I would say that %p is preferred. Maybe this[^] link will help.
|
|
|
|
|
%u is not a good choice for outputting memory addresses.
Personally, I use %p or %x for memory addresses.
Look here for printf type fields - printf Type Field Characters[^]

As shown below, there are a few functions in CButton, but i want to change its behaviour by dealing with
virtual void DrawItem(LPDRAWITEMSTRUCT lpDrawItemStruct) . Yes, just this one and only one functon. It would generate more code than expected if I derive a class from CButton. I wonder if it possible to process this function without Subclass, and not use derivation. If so, how?
Remarks: I must use MFC, it's so hard to use pure Win32 API.

What does that have to do with drawing a CButton? Hooks are system wide so you would need to capture every drawing message and then decide whether it was for your control or not. That's like using a big hammer to crack a small nut.

Inheritance is the natural way for doing that. Any other way (if feasible) would be contrived.

Hi.
A friend of mine wrote this crazy function in VB and i have translated it to C++ in hopes that we could get a bit better performance. I guess the performance might be a bit better but it is still an enourmous amount of loops to go through.
Do you have any suggestions on how to optimize this loop or perhaps replace it completely to be able to finish all iterations in a managable time? Is it hard to have it run on the GPU and would that improve anything?

The C++ standard template library (STL) comes with a lot of algorithms optimized for performance.
So if you can tell me what the above code is trying to do, maybe I could suggest an STL algorithm that does the same.
Not sure if the GPU will be able to do this, because I see a lot of data dependencies between the loop variables.
AFAIK, GPU programming needs the loop variables to be independent of each other.

Hi and thanks for the answer.
The code above is trying every combination of values 1-70 and is supposed to output them to an array of 20 values.
Example output each iteration: arrVals[] = {3, 6, 12, 15, 22, 26, 29, 34, 37, 41, 44, 48, 51, 54, 57, 61, 63, 67, 69, 70};
Each position in the array has limitations to how big or small they can be as follows:
int llim [20] = {1, 2, 5, 8, 11, 14, 17, 21, 24, 28, 31, 35, 38, 42, 45, 50, 53, 58, 61, 66};
int hlim [20] = {6, 10, 14, 19, 22, 26, 29, 34, 37, 41, 44, 48, 51, 54, 57, 61, 63, 67, 69, 70};
The array arrVals is sent to another function each iteration to decide if the current row of 20 is usable or not.
I hope this is clear enough, please ask if not.

I think the std::next_permutation would be perfect tough i need conditions for it so that it doesn't try to find every permutation for all 70^70, which would take forever.
I'm actually not sure if it will be fast enough even with conditions.
I'm obviously not good enough with C++ to manage this :p

I have added (to the working library) GUID for CLSID_IMGSinkFilter to uuids.h header using this :
// 1d4d3676-96ef-4cd7-a3d7-07fac0d0c585
OUR_GUID_ENTRY(CLSID_IMGSinkFilter,
0x1d4d3676, 0x96ef, 0x4cd7, 0xa3, 0xd7, 0x07, 0xfa, 0xc0, 0xd0, 0xc5, 0x85)
This GUID will be used in static library.
The library compiles and builds, by itself.
The main application complies but it fails to link to the GUID with following error:
VidCapLib.lib(_Graph.obj) : error LNK2001: unresolved external symbol _CLSID_IMGSinkFilter
Debug/TCC_MDI.exe : fatal error LNK1120: 1 unresolved externals
So the VidCapLib.lib is not complete.
What did I missed?
Any help as always will be appreciated.
Cheers
Vaclav
