Hi, all!
Does anyone of you know how to apply C++ to program an algorithm named "Subspace iteration", which is mainly for the calculation of eigenvalues and eigenvectors.
Thank you very much for your guidance!

How can I find out what OS my program is running under. I need to be able to distinguish between NT 4.0 and Win 2K.
Regards,
SAK

you can use GetVersionEx
OSVERSIONINFO.dwMajorVersion will be 4 for NT 4.0 and 5 for Win 2K

Hi there
I am learning Visual C++ and tring to build some kind of Visual CAD Builder
on MFC{ like Visio}
But of course I experience lack of knowledge
So, can anybody help me with that and send me link or some project where I can learn how to do that.
Thank you

You'll have to be more specific about the areas you are struggling with. I suggest reading up on GDI and GDI plus. Also the Scribble tutorial that comes with Visual C++ will help you build the basic framework.

Do you know any good reading on GDI
GDI plus.... I have never heard about that

Clim, I think your trying to jump too far ahead if you haven't yet heard of GDI (CDC). Doing so will be damaging for you for two reasons, you'll miss the basics of graphics work and risk being disillusioned with your programming experience if you fail on your early projects.
As suggested, the scribble sample program is a good place to start, because it teaches the 'object' method of drawing.
After going through the scribble tutorial to get the basics, I would suggest setting up an almost bare-bones project with just a standard View. Then work through the GDI functions, to see what they do and how there work. Then try some drawing objects of your own.
For example you might have a box class
class CBox : public CObject
{//data only class
CRect m_Box;
CPoint m_Possition;
COLORREF m_BorderColor;
COLORREF m_FillColor;
};
You might decide then to add intelligent shapes,
class CCircle : public CObject
{//Intelligent class
CRect m_BoundingRect;
double GetRadius();
double GetCircumference();
};
You could even, once you have done the ground work, create a CDC class of yuor own that understands your own objects.
But first you need to study CDC. Your C++ has already got a wealth of information of how to get started, don't waste your money on a £50 book until you have fully explored what you have and then know exactly which area of graphics you need help with, if any.
We do it for the joy of seeing the users struggle.

Sorry, I meant to also say that text is an important area of graphics, thats still a CDC thing, and a plain View is the best place to work with that too.
You will need to understand the CFont/LOGFONT and how to calculate the dimensions etc.
You have a lot of work to do, but its best to just nuckle down and get on with it, you'll need to write interfaces in a your programming so the sooner you get these lessons out of the way the better.

Hello, I need a program, which decode header file and extract name of the function. Please can you help me? Where i can find describtion of header file? 
Thank
|
|
|
|
|
Are you talking about a C/C++ .h file. These are text files. You could load the .h file into a string and parse the string looking for the function type (void,int, etc) From there if you find the first ( the text inbetween the two postions will be your function name.

I've been using C# for about a year now and I'm enjoying it. (first lang. I've enjoyed).
I do have some definite problems with it though:
1. If it's compiling to the same MSIL as VB.NET and VB.NET has untold hacks to get it to the place that it is now (like adding OO to it), then how on earth can the C# only compile to the same thing. This is a brand new language - barring the fact that Anders Hejlsberg also worked on VJ++. 
2. The fact that C#'s main competitor is ... VB.NET. If there was no VB.NET then the current VB "programmers" would be forced to move into the world of Java/C#/Delphi.
3. The MS coders used MS Frontpage to write the .NET splash -- take a lot, I kid you not.

1. MSIL is an intermediate language. It has very little to do with VB.NET. With the right compiler you could compile almost any language to MSIL including Perl, Java, C++, C, Fortran, etc.
2. VB.NET is not C#'s main competitor. Where did you get this idea? So the rest of your logic is a bit flawed.
3. so.
President of the Group for the Abolishment of Visual Basic Programmers World-Wide.
From your logic you almost sound like a VB programmer  Wouldn't that be suicide?

How about a win32 example which shows how to change the background color of individual items of a listview control ?
I have been trying to find and know how to do this but till now without much success

See Neat Stuff to do in List Controls Using Custom Draw. It uses MFC, but it's just message handling so it'll be simple to change the message handler over to straight Win32.

Hi Michael
Thanks for replying. I have seen that code. but it doesn't seemt o work for me in Win32 or maybe I have done something wrng i just can't figure it out.
Would appreciate help on this. I have posted the problem yesterday in the Visual C++ discussion board but nobody replied.
I have given details of my problem there and I can't seem to figure out the problem. I will put the stuff here again.
I am making a win32 dll (non MFC) and i have these three functions which I am using (i have more functions but may not be exactly useful here)
HWND WINAPI EXPORT MakeListView(HWND hwnd,long x ,long y,long width,long height)
{
INITCOMMONCONTROLSEX iccex;
iccex.dwICC=ICC_LISTVIEW_CLASSES; //ICC_WIN95_CLASSES;
iccex.dwSize=sizeof(INITCOMMONCONTROLSEX);
InitCommonControlsEx(&iccex);
hwndTT = CreateWindow("SysListView32","",WS_CHILD | WS_VISIBLE | WS_BORDER | LVS_REPORT | LVS_SHOWSELALWAYS , x, y,width,height,awParam->hwnd, NULL, hInst, NULL);
ListView_SetExtendedListViewStyle(hwndTT, LVS_EX_FULLROWSELECT );
//initialize the LVCOLUMN structure
//The LVCOLUMN is used for adding title to the header of listview.
lvc.mask=LVCF_FMT | LVCF_WIDTH | LVCF_TEXT | LVCF_SUBITEM;
lvc.cx=100;
lvi.mask = LVIF_TEXT | LVIF_IMAGE | LVIF_STATE;
lvi.state = 0;
lvi.stateMask = 0;
return(hwndTT);
}
//The above sample code is for making a listview and it returns a handle
void WINAPI EXPORT ListChangeItemColor(HWND listviewhandle)
{
glPrevWndProc = SetWindowLong(listviewhandle, GWL_WNDPROC,(LONG)(WNDPROC)DoNotify);
}
//this is the second function which accepts the listviewhandle and attempts to use the window procedure of the ListView. I think this is the problem, not sure if i am doing this right.
long DoNotify(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam)
{
switch(msg)
{
case WM_NOTIFY:
{
LPNMLISTVIEW pnm = (LPNMLISTVIEW)lParam;
switch (pnm->hdr.code)
{
case NM_CUSTOMDRAW:
{
LPNMLVCUSTOMDRAW lplvcd = (LPNMLVCUSTOMDRAW)lParam;
if(lplvcd->nmcd.dwDrawStage == CDDS_PREPAINT)
return CDRF_NOTIFYITEMDRAW;
if(lplvcd->nmcd.dwDrawStage == CDDS_ITEMPREPAINT)
{
if(!(lplvcd->nmcd.dwItemSpec % 3))
{
GetClientRect(hwnd,&rect);
MessageBox(NULL,"I am here","help",MB_OK);
lplvcd->clrText =RGB(255, 0, 0);
lplvcd->clrTextBk = RGB(0,0,0);
InvalidateRect(hwnd,&rect,FALSE);
return(CDRF_DODEFAULT);
}
}
}
}
}
default:
return(CDRF_DODEFAULT);
}
return CallWindowProc((WNDPROC)glPrevWndProc, hwnd, msg, wParam, lParam);
}
//This is the window procedure which i call from ListChangeItemColor
Could you tell me what i am doing wrong. I have thought of this for almost the entire 1 whole day and for some reason can't seem to get it working. I saw your code (MFC version) but i still don't know what i am doing wrong.
HELP

Hi all,
I want to write a program that can run a cgi scrip from a domain in VC++.
And it communicate with domain through proxy.
If you have any relative information, please show me! Thank you very much!
Best regards,
BUNG

CGI scripts are run by sending a HTTP GET or POST request, and the results will be in the HTTP response. If you are using a proxy, you send the HTTP request to the proxy instead of the final destination, and give the absolute URI of the CGI script in the request.

I need samples of code on how to
create win32 programs with a visual
inferface like KPT Bryce and KPT plugins for photoshop.
So basically, nothing like the standard windows interface.
I've been trying to sort this for years, and I believe
it's an important issue with XP basically looking like Mac Applications
- visually appealing. It's what customers want.
I've only found samples on designing curvy windows.
Is there a standard way (easy way) for creating KPT Bryce like
interfaces??
