In your child frame class, add the following override:

BOOL CChildFrame::PreCreateWindow(CREATESTRUCT& cs)
{
// TODO: Modify the Window class or styles here by modifying
// the CREATESTRUCT cs

if( !CMDIChildWnd::PreCreateWindow(cs) )
return FALSE;

cs.style = WS_CHILD | WS_VISIBLE | WS_OVERLAPPED | WS_CAPTION | WS_SYSMENU
| FWS_ADDTOTITLE | WS_MINIMIZEBOX | WS_MAXIMIZEBOX | WS_THICKFRAME;

return TRUE;
}

To Maximize a MDI-Child on Opening.

BOOL CChildFrame::PreCreateWindow(CREATESTRUCT& cs)<br />
{<br />
	// TODO: Modify the Window class or styles here by modifying the   CREATESTRUCT cs<br />
	if( !CBCGPMDIChildWnd::PreCreateWindow(cs) )<br />
		return FALSE;<br />
	cs.style |= WS_MAXIMIZE|WS_VISIBLE;<br />
	return TRUE;<br />
}

And then, don't forgert to remove ResizeParentToFit() in OnInitalUpdate() from your CFormView based Class!

Sorry, copied the wrong block.... THis is the one:

void CChildFrame::ActivateFrame(int nCmdShow)
{
// TODO: Modify this function to change how the frame is activated.

nCmdShow = SW_SHOWMAXIMIZED;
CMDIChildWnd::ActivateFrame(nCmdShow);

Are you referring to an IP statistics? One solution is GetIpStatistics().

One solution is getsockopt(). For this api, you will have to call it for each socket status, i.e. connect, send, etc.

I know nothing here -- but this seems like the kind of thing you shouldn't be able to do. Actual handles should be private to the application, unless they make em global?

Some handles in windows are global to the OS, like mutexes, thread and process handles.

Get data from a password protected webpage

Hi,

I try to get data from a password protected webpage and need a little help.

At first I want to describe the situation in the browser.
When I call the webpage, I got a page with a little login screen. This is realized by some javascript code. I fill in the username and password, click on 'login' and voila, there are my wanted data.

I looked at the javascript code an noticed the names of the fields. I tried to call the webpage directly with:

http://<address>?<NameOfUserField>=<username>&<NameOfPasswordField>=<password>&action=<actionname>

... and it works fine. Now I had to do the same in my MFC-Projekt but I failed. I was unsuccessful with the following two attempts

#################
## First Attempt
#################
********************************************************************************************************
...
CInternetsession InternetSession(_T("AppName"),1, INTERNET_OPEN_TYPE_PRECONFIG);
char Url = "<address>?<NameOfUserField>=<username>&<NameOfPasswordField>=<password>&action=<actionname>";
CString strServerName; // Server
CString strObject; // directory
INTERNET_PORT nPort; // port
DWORD dwServiceType; // accesstype
AfxParseURL(Url, dwServiceType, strServerName, strObject, nPort)
DWORD dwHttpRequestFlags = INTERNET_FLAG_RELOAD;
CHttpFile *pHttpFile = pHttpConnection->OpenRequest(CHttpConnection::HTTP_VERB_GET,// or HTTP_VERB_POST
strObject, NULL, 1, NULL, NULL,
dwHttpRequestFlags);
pHttpFile->SendRequest();
CString sz;
while (pHttpFile->ReadString(sz)){
...
}
********************************************************************************************************
#################
## Second Attempt
#################
...
CInternetsession InternetSession(_T("AppName"),1, INTERNET_OPEN_TYPE_PRECONFIG);
char Url = "<Only_Address_without_parameter>";
CString strServerName; // Server
CString strObject; // directory
INTERNET_PORT nPort; // port
DWORD dwServiceType; // accesstype
AfxParseURL(Url, dwServiceType, strServerName, strObject, nPort)
DWORD dwHttpRequestFlags = INTERNET_FLAG_RELOAD;
CHttpFile *pHttpFile = pHttpConnection->OpenRequest(CHttpConnection::HTTP_VERB_GET,// or HTTP_VERB_POST
strObject, NULL, 1, NULL, NULL,
dwHttpRequestFlags);
CString szHeader = _T("<NameOfUserField>=<username>&<NameOfPasswordField>=<password>&action=<actionname>");
pHttpFile->AddRequestHeaders(szHeader);
pHttpFile->SendRequest();

CString sz;

Any Idea's?

Writing CString to file - problems

Berkut27-May-03 3:11

hi,

i am trying to save a CString to a file. I'm doing this like this:

<br />
CStdioFile cfFile(strPath, CFile::modeCreate | CFile::modeReadWrite | CFile::shareDenyNone);<br />
CArchive ar(&cfFile, CArchive::store);<br />
<br />
cfFile.WriteString(strContents);<br />
<br />
ar.Close();<br />
<br />
cfFile.Close();<br />

This works, but it always places weird characters after the end of the contents of the string.

I'm deleting the file first before saving it, and I know the contents of the CString are correct. Any ideas?

thanks

How do you know the "writing" code is faulty? What are you using to verify the weird characters?

Of course it will place wierd characters at the end of the string because you used CArchive. CArchive will insert its own codes. Remove the stuff for CArchive and you should be ok. Also check the documentation because I beleive the file may also be stored as binary and not text.

CArchive is an object-store -- not a text file.... it seems to be storing the CString "object", not the string....

You don't want to open a record set for this call. See the following code:

   _ConnectionPtr pCon;<br />
<br />
    _RecordsetPtr pRecordset;<br />
    pCon = m_pConnection ;  //  Please see previous examples and how to use ADO Connection object<br />
<br />
<br />
        // string I/O stream<br />
    basic_stringstream<wchar_t> strSQLStatement;<br />
    variant_t vntRecordAffected;<br />
<br />
    strSQLStatement <<L"INSERT INTO Access(Name, HTML) VALUES('myName', 'myHTML' ) ";<br />
    bstr_t strSQLstmt = strSQLStatement.str().c_str();<br />
<br />
    try<br />
    {<br />
        pCon->Execute(strSQLstmt, &vntRecordAffected, adCmdText );<br />
    }<br />
    catch( _com_error &e)<br />
    {<br />
        // get info from _com_error<br />
        _bstr_t bstrSource(e.Source());<br />
        _bstr_t bstrDescription(e.Description());<br />
        TRACE("%s", e.ErrorMessage());<br />
      }<br />
    catch(...)<br />
    {<br />
        TRACE("*** UNHANDELED EXCEPTION ***");<br />
    }
