Re: How do you initialize a structure with a CPoint member?

CPoint cannot be initialized with an initializer list probably because it has one or more constructors, and has a base class.

OR:

typedef struct {
int x;
int y;
} MyCPoint;

struct s_Door{
s_Door();
MyCPoint InsertionPt;
int iPline;
int iEach_Pline[1];
int iVert;
MyCPoint Vert[5];
CPoint adk;

}

s_Door::s_Door() : InsertionPt( 0, 0), iPline( 1 ), ... adk( 0, 0 )
{
// anything you want to addd....
}

ftp problem

Hi,

I have implemented an FTP application, which will schedule itself to run daily by using SetTimer, once it’s started. Everyday it will FTP-get a plain text file from a remote server using MFC classes CInternetSession and CFtpConnection.

The plain text file’s name will be the same, but the content is updated daily. The problem I’m having is the first time I start the application, it gets the text file of that day, but then it will get the same file, even though the content of the remote file has already been updated. It seems like the file is cached somewhere. If I stop the application and re-start it, again it will be fine the first time.

The code is below:

CInternetSession session(_T("DBAdmin"));
CFtpConnection* ftp;

session.SetOption (INTERNET_OPTION_CONNECT_TIMEOUT, 30000);
session.SetOption (INTERNET_OPTION_CONTROL_SEND_TIMEOUT, 30000);
session.SetOption (INTERNET_OPTION_CONTROL_RECEIVE_TIMEOUT, 30000);
session.SetOption (INTERNET_OPTION_DATA_SEND_TIMEOUT, 30000);
session.SetOption (INTERNET_OPTION_DATA_RECEIVE_TIMEOUT, 30000);

try
{
ftp = session.GetFtpConnection (strIP, strLogin, strPwd, iPort);
if (ftp)
{
if (!ftp->GetFile (strSrc + strFileName, strDest + strFileName))
}
}

Is this a setting problem or a programming one?

Thanks in advance.

Tony

I suspect there is a problem on the server side. The server may not be updating its data relative to the actual file. In other words, the server is no aware that the file has changed.

When you construct the CInternetSession object, pass the flag INTERNET_FLAG_DONT_CACHE as the Flags parameter:

CInternetSession session(_T("DBAdmin"), 1, INTERNET_OPEN_TYPE_PRECONFIG, NULL, NULL, INTERNET_FLAG_DONT_CACHE);

Installing VC6 SP5

I just downloaded SP5 from msdn and I choose the multi-part download. So I have 11 files numbered 1 to 11 this is the SP5 core, no problem with those.

There are aslo 3 files called vs6sp5s1.exe, vs6sp5s2.exe and vs6sp5s3.exe. When I unpack them they are full of headers, .lib and so. I don't know how to install those files, should I unzip them in the same folder as the SP5 core. It seems odd to me as SP5 is mainly composed of CAB files when the 3 others are a bit messy.
Any info someone ?

Thnak in advance Wink | ;)

Just for yor information, you need to unzip all files into one folder and then run the Setup.exe that came with the 1st cab file.

Hi guys
I've read the following optimizations switches
/G5 Optimizes for Pentium processor.
/G6 Optimizes for Pentium Pro processor.

But exists some newer switches to optimize for Pentium III or Pentium 4 processors?

Get the Intel C++ compiler if you want the fastest possible code for P4.

How to check if bit STORE_RTF_OK is set in message store provider?

Re: Extended MAPI

David Crow11-Jun-03 4:24

Call the message store's GetProps() method to retrieve the PR_STORE_SUPPORT_MASK property. Then check the STORE_RTF_OK bit.

Re: Extended MAPI

David Crow

if ((pPropVal->Value.l & STORE_UNCOMPRESSED_RTF) == STORE_UNCOMPRESSED_RTF)

will get it.

Re: Extended MAPI

David Crow12-Jun-03 2:33

David Crow

12-Jun-03 2:33

Which is incorrect. The expression (pPropVal->Value.l && STORE_UNCOMPRESSED_RTF) evaluates to 1 so of course the whole condition is TRUE. To AND two values, you need to use the '&' operator.

Have you tried printing the hex value of pPropVal->Value.l? It'll show you what bits are set and what bits aren't.

CRichEditCtrl slowing down my application

I am permanently logging lines of text with a "\r\n" at the end to a CRichEditCtrl. That way, the CRichEdit appends a new line of text with every call of ReplaceSel("SomeText\r\n") and keeps scrolling down. Stupidly the whole thing gets very sluggish as Confused | :confused:

the amount of text increases. I saw applications doing this kind of "logging" for several hours without getting slower. Does anybody have an idea how to do this ???

Compile problem

Roger Allen11-Jun-03 4:03

11-Jun-03 4:03

I have a problem I have been scratching my head on for a few hours now. I have a class in a project which has not changed in 6 months, but when I came to build the whole project this morning I got about 22 errors in it to do with some friend functions for serialzation trying to access a protected member variable.

	// serialization
#ifdef _DEBUG
	friend CDumpContext& AFXAPI operator<<(CDumpContext& dc, CGoodTime time);
#endif
	friend CArchive& AFXAPI operator<<(CArchive& ar, CGoodTime time);
	friend CArchive& AFXAPI operator>>(CArchive& ar, CGoodTime& rtime);
#pragma message("    GoodTime.h")
protected:
   void SetDays( tm *ptm );

private:
	tm m_time;
};

The actual implemenations of these functions throw up the compile errors. Now I have added in a #pragma message command to make sure the correct header is being used, and it is. So the next thing I tried was the compiler /P option to get a copy of the output that goes into the compiler, needless to say with the /P option it compiles without any problems, remove /P and they come back.

Any ideas why this should be so?

I know this does not solve your problem, but I just wanted to clarify in case you were expecting something that was not meant to happen.
