I would be inclined to use:

void CMyClass::OnUnload()
{
    CInternetSession m_Inet;
    CFtpConnection* pConnection = NULL;
 
    try
    {
        pConnection = m_Inet.GetFtpConnection(sServer, m_sUsername, m_sPassword));
        ...
    }
    catch (CInternetException e)
    {
        TCHAR szCause[255];
        e.GetErrorMessage(szCause, sizeof(szCause));
        AfxMessageBox(szCause, MB_ICONERROR); // does this display when invalid credentials are used above?
    }
        
    if (pConnection != NULL)
        pConnection->Close();
 
    delete pConnection;
}

(Thanks for your answer.)

"CInternetSession m_Inet;" is declared as a class member but not initialized.

The "AfxMessageBox()" declared in the "catch" statement is not displayed.
The "GetFtpConnection()" function displays the following error messsage:
"220 NET+OS 6.3 FTP server ready"
"530 Not logged in"
and then it makes my function exit.
When I set some breakpoints with VS6, the debugger does not stop on them.
The end of my function is never reached!

Any more ideas, please?
Pascal

Thanks and regards
Pascal

Which would seem problematic since you also have one declared in the OnUnload() method.

In fact, I've moved the declaration from the method to the class because:
- when declaring in the method: the error message box contains square characters Dead | X|

- when declaring in the class: the error message box contains understandable characters Unsure | :~

In a standard Windows message box with a "OK" button to close it...

Maybe WinInet is not compatible with a UNICODE compilation?!
D'Oh! | :doh:

EMF object handling

Hi all,

I have an application which shows map of a city. The picture is stored as EMF. The application has zoom in and zoom out facility.

I need to hide detailed texts and lines when zoom out to small, for better clarity of the city map. The text and lines will have different sizes. The small sized objects need to be hidden.

I am trying to use EnumEnhMetaFile for this purpose. But I dont know how to identify the size of text and lines in the EnhMetaFileProc with the current size of the image.

Could anybody help me?

Thank you.

i might be wrong, but i don't think you can do conditional drawing inside EMFs. at least, you can't save the condition - of course you can draw based on whatever logic you want, you just can't save the app logic along with the GDI commands.

Ofcourse I did some logic inside my app for this. Let me show some code snippet that I did experimentally.

int CALLBACK EnhMetaFileProc( ...... )
{
static bool bTextout = true;
if( lpEMFR->iType == EMR_SELECTOBJECT )
{
PEMRSELECTOBJECT p = (PEMRSELECTOBJECT)lpEMFR;
LOGFONT lf = { 0 };
if( sizeof(lf) == ::GetObject( lpHTable->objectHandle[p->ihObject], sizeof( lf ), &lf ))
{
if( lf.lfHeight >= -35 )
bTextout = false;
else
bTextout = true;
}
}
if(( lpEMFR->iType == EMR_EXTTEXTOUTW ) || ( lpEMFR->iType == EMR_EXTTEXTOUTA ))
{
if( !bTextout )
return TRUE;
}
::PlayEnhMetaFileRecord( hDC, lpHTable, lpEMFR, nObj );
return TRUE;
}

My problem is that I dont know how to identify the scaling. For example, how can I identify the following inside the EnhMetaFileProc...
EnumEnhMetaFile( dc, m_hEMF, EnhMetaFileProc, 0, CRect( 0, 0, 100, 100 ));
EnumEnhMetaFile( dc, m_hEMF, EnhMetaFileProc, 0, CRect( 0, 0, 500, 500 ));
Also I am not sure whether this is the correct method to do.

I did not get any details about this yet from MSDN or from net... Frown | :(

Hi
I have worked with some nice apps like Remind! 5.45 and Macro Toolsworks 6.31. Many crackers have reported that such apps are not easy to crack.

Any guess, how they would have implemented crack-protection. If any one has idea or experience how to implement such crack-protection.

I need to implement similar crack protection in our VC++/MFC App. The idea is to make it more dificult to crack (i.e. with some check for anti-debugging, anti-cracking and anti-softice etc.)

I truly appreciate any help/ideas/reference links.

Thanks
Ana

Sorry,

I have an initial string, in which I have to find a substring and replace it with a diffrent one. Like Replace() from CString.

Thanks,
