(r+g+b)/3 it only an approssimation of the right formula... I used this in past to implement a fast algorithm, but of course it isn't exact.

Our eye is more sensitive on the green light and less on red.
So, that constants are related to the features of the human eye.
hope it helps.

Problem with calling web service using HTTPSendRequest and InternetReadFile on EVC 3.0.

I am trying to call a web service on Pocket PC (ARM processor) using HTTPSendRequest. But when doing InternetReadFile it is giving me incomplete string like this

I got such incomplete information after calling this web service 2 to 3 times. Initially 2 times i got blank reply.

Now When I used HTTPQueryInfo it showed following message

H T T P / 1 . 1 4 0 0 B a d R e q u e s t
S e r v e r : M i c r o s o f t - I I S / 5 . 0
D a t e : F r i , 2 8 S e p 2 0 0 7 0 8 : 3 5 : 5 1 G M T
X - P o w e r e d - B y : A S P . N E T
X - A s p N e t - V e r s i o n : 2 . 0 . 5 0 7 2 7
C a c h e - C o n t r o l : p r i v a t e
C o n t e n t - L e n g t h : 0

My web service contains just one method “HelloWorld” which does not take any input parameters and returns the “HelloWorld” string to the calling application.

My code of calling web service is following.

LPTSTR AcceptTypes[2] = {TEXT("text/xml"), NULL};
DWORD dwFlags = INTERNET_FLAG_NO_CACHE_WRITE |INTERNET_FLAG_KEEP_CONNECTION;

HINTERNET hNet = InternetOpen(L"EvcWebService", INTERNET_OPEN_TYPE_PRECONFIG,
NULL, NULL, 0 );

if (hNet)
{
HINTERNET hSession = InternetConnect(hNet, _T("10.37.54.93"), INTERNET_DEFAULT_HTTP_PORT, _T(""), _T(""), INTERNET_SERVICE_HTTP, 0, 0);

if (hSession)
{
HINTERNET hRequest = HttpOpenRequest(hSession, _T("POST"), _T("/TestService/Service.asmx?wsdl"), TEXT("HTTP/1.1"),NULL, (LPCTSTR*)AcceptTypes, dwFlags, 0);

if (hRequest)
{
TCHAR szSoapAction[256];
_tcscpy( szSoapAction, _T("Content-Type: text/xml;charset=utf-8\n") );
_tcscat( szSoapAction, _T("SOAPAction: \"") );
_tcscat( szSoapAction, _T("http://tempuri.org/HelloWorld") );
_tcscat( szSoapAction , _T("\"\0\r\n\r\n") );

TCHAR szSoap[512];
_tcscpy(pszSoap, _T("") );
_tcscat(pszSoap, _T("<soap:envelope xmlns:soap="\"http://schemas.xmlsoap.org/soap/envelope/\"" \="" xmlns:xsi="\"http://www.w3.org/2001/XMLSchema-instance\"" xmlns:xsd="\"http://www.w3.org/2001/XMLSchema\"">") );

_tcscat(pszSoap, _T("<soap:header>") );
_tcscat(pszSoap, _T("") );
_tcscat(pszSoap, _T("<soap:body>") );

_tcscat(pszSoap, _T("<helloworld \
="" xmlns="\"http://tempuri.org/\"">") ); //
_tcscat(pszSoap, _T("") );

_tcscat(pszSoap, _T("") );
_tcscat(pszSoap, _T("") );

BOOL bSent = HttpSendRequest(hRequest, szSoapAction, _tcslen(szSoapAction), szSoap, _tcslen(szSoap) );

if(bSent)
{
called HTTPQueryInfo.....
}

This HTTPQueryInfo returns bad request. But this code works fine on Win32 and give Bad Request on WinCE.
Please let me know how should i build soap packet for EVC so that it will call web service on Pocket PC?

Repainting of Internet Explorer

Hi All,
I have developed a ActiveX control that is invoked in IE(Internet Explorer) using Java Script. Now when the control is executing something, and the user switches to some other window and then back to IE, IE does not repaint itself. The screen is not getting painted uniformaly and the control does not get displayed until and unless the processing for the task being executed is over.
Has someone ever encountered this problem? I want IE to show even when the processing is done within the ActiveX control.
Any help would be appreciated.

I am making a toolbar for a website. initially the toolbar is normal and when the yser login the toolbar changes and takes the setting for the logged in user as is in the case of Yahoo.
If the user does not work on the website application for 18 minutes i.e. if he takes no action he should be logged out and the toolbar should be in its initial state.
Now the problem for me is i am not able to track that no event has been fired and the session of 18 minutes has expired and because of which I am not able to change my toolbar as a aresult of which what happens is that even if the yser is logged out of the site after 18 minutes still my toolbar is having the users settings.

I am using WIN32 ATL and WTL.

Please help me what to do.

Thanks in Advance.

in a CListCtrl every first column in a row is an item and every other column is a subitem of the item.

I mean:

If a Matrix of MxN, then you have M rows, where column 1 are items and columns [2, N] are subitems. So you have M items and N-1 subitems.

So you can use:

CListCtrl::GetColumn
BOOL GetColumn( int nCol, LVCOLUMN* pColumn ) const;

Return Value
Nonzero if successful; otherwise zero.

put it in an iteration and the last time you get nonzero as return is the number of columns.

Or doing it by associating your programm to office in the registry,

or doing a message-spy looking at which programm is being called and, if office... then call your as well.

But sorry, I can't tell you code.

If I need to do it I will do it, but at the moment... I can give you (and I have given you) the idea how to go in that way. There are articles and message in forum in this website. And you have google. Use it Smile | :)

I have read an article that intercepts mesenger and makes some things. I guess is something similar.

Look for info about HOOKS, THREADS and MESSAGES RECEPTION you should find something to use

Send Unsigned Char* using Winsock.h

How to send unsigned char* using winsock.h?
The send function in winsock that I know is only accepted char*.
Thanks.

So what exactly is the problem? As long as the receiving end casts what it gets to an unsigned char, it should be fine.

The server is only accepted unsigned char, and I can't change the configuration (it's must not).
So my client application should send unsigned char.
The problem : is winsock able to send unsigned char?

Not unless you first cast it to a signed char.

I had already found that winsock is send the value of the char, it depends on the length parameter.
