Visual C++ 6.0/SP5
I have written a program that sets folders to be either "hidden" or "normal" (based on user selections). This program works just fine on Win2K and WinXP, but Win98 users aren't seeing any success at all. Here's the code I'm using:
void CMyClass::ChangeFolderAttributes(CPersonality* pItem)
{
if (g_pPersonHelper->GetChangeTrackFiles())
{
CTracksINI* pTracksINI = GetSimTrackList(SIM_NR2K3);
if (pTracksINI)
{
CString sInstalledTrackDir = "";
CString sInstalledFullPath = "";
int nInstalledCount = pTracksINI->GetCount();
for (int i = 0; i < nInstalledCount; i++)
{
sInstalledTrackDir = pTracksINI->GetTrack(i)->GetTrackDir();
sInstalledFullPath.Format("%stracks\\%s", m_sSimPath, sInstalledTrackDir);
bool bInTrackSet = g_pTrackSetHelper->GetTrackSet(pItem->GetTrackSet())->TrackIsInSet(sInstalledTrackDir);
DWORD dwDesiredAttrib = (bInTrackSet) ? FILE_ATTRIBUTE_NORMAL : FILE_ATTRIBUTE_HIDDEN;
BOOL bResult = SetFileAttributes((LPCTSTR)sInstalledFullPath, dwDesiredAttrib);
}
}
else
{
}
}
else
{
}
}
I've scoured the MSDN stuff, google the API calls, and checked a number of programming bulletin boards, but there is no mention of an incompatibility.
The one thing I did notice is that when I manually select a folder and set it to hidden (using Windows Explorer) Win2k asks is I also want to hide all of the sub-items. I don't have a Win9x box, so I can't see if Win9x does the same thing, but I don't remember that happening.

Two things I'd change.
1. The line that builds the full path:
sInstalledFullPath.Format("%stracks\\%s", m_sSimPath, sInstalledTrackDir);is assuming backslashes in certain places. Is that always right? I'd use the shlwapi functions instead (like PathAppend()) to build the name.
2. You're calling SetFileAttributes() without getting the existing attributes first. This results in you unsetting the FILE_ATTRIBUTE_DIRECTORY attribute, which might be what's causing the error. You should always get the current attrs and modify them. I'd do:
DWORD dwAttrs = GetFileAttributes ( sInstalledFullPath );
DWORD dwDesiredAttrib = bInTrackSet ? FILE_ATTRIBUTE_NORMAL : FILE_ATTRIBUTE_HIDDEN;
if ( INVALID_FILE_ATTRIBUTES == dwAttrs )
else
{
dwAttrs &= ~(FILE_ATTRIBUTE_NORMAL | FILE_ATTRIBUTE_HIDDEN);
dwAttrs |= dwDesiredAttrib;
BOOL bResult = SetFileAttributes ( sInstalledFullPath, dwAttrs );
}

Hi,
I wrote a program using the CFile object.It is giving the following error.
c:\program files\microsoft visual studio\vc98\mfc\include\afxv_w32.h(14) : fatal error C1189: #error : WINDOWS.H already included. MFC apps must not #include <windows.h>
I included windows.h and afx.h as headers.What else should I include to get rid of this problem

Don't inlcude windows.h, afxv_w32.h takes care of that for you via afx.h.

My System-Menu only contains 'Close' and 'Move' commands.
What am I missing ? any specific style ?

I have them both but alas 
My window wouldn't respond to the 'minimize-all' button until I added WS_MINIMIZEBOX, but still the option doesn't show on my window

I use SHBrowseForFolder, select the Recycle-Bin, get a PIDL, and fail to convert it to a legitimate path.
Is this by design ?
|
|
|
|

I think so, because there is no single one recycle bin. IIRC, there's a recycle bin on each drive. The one you see on the deskop is just a "union" of all the individual recycle bins.

Hi. I am trying to connect to a remote module by TCPIP. It keeps failing at gethostbyaddr. THe error is WSANO_DATA. MSDN says that this means "Valid name, no data record of requested type." What does this mean? What do I need to change or do for this. From hyperterminal, it will connect correctly so there must be something simple to do to take care of this I think.
THanks!!

Hi,
I found this article about catching outlook events:
http://www.codeproject.com/internet/outlookxpevents.asp?target=NewMail%7Cevent#xx635951xx
With this code you can catch the event, when a new mail is in the inbox.
It works fine !
I would like to catch an events when a new contact is saved or when a new appointment was created.
Theres´s no way for me to do this !
The problem is, that the FindConnectionPoint returns an error for the ItemEvents ConnectionPoint.
This is my code, which is same as in the article but only changed to the ContactItem.
//In the dialog class
1. ItemEvents m_OutlookContact;
2. //Add an event handler for the Application object.
m_pAppEventListener = new CAppEventListener();
m_pAppEventListener->AddRef();
m_pAppEventListener->AttachToSource
( m_OutlookContact.m_lpDispatch );
//In the cpp class where the EventListener is defined
STDMETHODIMP CAppEventListener::AttachToSource
( IUnknown* pEventSource )
HRESULT hr = S_OK;
IConnectionPointContainer* pCPC = NULL;
hr = pEventSource->QueryInterface( IID_IConnectionPointContainer,
(void**)&pCPC );
if (SUCCEEDED(hr)){
hr = pCPC->FindConnectionPoint( IID_ItemEvents,&m_pConnectionPoint);
if (SUCCEEDED(hr)){
hr = m_pConnectionPoint->Advise( this, &m_dwConnection );
}
pCPC->Release();
}
return hr;
}
//In the header class of the event listener I defined the item events from
the outlook typ libraries (OLE/COM Object Viewer)
const IID IID_ItemEvents=
{0x0006303A,0x0000,0x0000,{0xc0,0x00,0x00,0x00,0x00,0x00,0x00,0x46}};
Why is &m_pConnectionPoint : 0x00000000 ?
Only when I change the IID_ItemEvents to the IID_ApplicationEvents, which is
{0x0006304E,0x0000,0x0000,{0xc0,0x00,0x00,0x00,0x00,0x00,0x00,0x46}}
the function returns OK.
Can someone help me please ?

Hello Everyone,
I need your sincere help in finding the suitable header file
for the wsnprintf() method. For finding the Domain Users in
Microsoft Active Directory Services(ADSI), i called the ADSI API i.e. FindUsers() to fetch the list of user objects
from a container or directory tree. For that the FindUser()
API code has used the method i.e. wsnprintf() for adding the filter.
RESULT FindUsers(IDirectorySearch *pContainerToSearch, // IDirectorySearch pointer to the container to search.
LPOLESTR szFilter, // Filter for finding specific users LPOLESTR *pszPropertiesToReturn, // Properties to return user objects found.
BOOL bIsVerbose)
This FindUsers() is the API where the definition of the ADSI API calls the wsnprintf() method like as below : DWORD
#define MAX_PATH 520
dwLength = MAX_PATH*2;
// Create search filter.
LPOLESTR pszSearchFilter = new OLECHAR[dwLength];
// Add the filter.
wsnprintf(pszSearchFilter, dwLength, L"(&(objectClass=user)(objectCategory=person)%s)",szFilter);
Please help me out in giving me the details about the header file and the .lib file to make the code compilable.
Thanks,
Derik

Are you sure you don't mean _snwprintf() that is declared in stdio.h?

Hello Everyone,
I am from CG Maersk, Chennai, India.I have problem while
compiling wsnprintf() function in one of my piece of COM code. I use this function to add the filter.
#define MAX_PATH 520
LPOLESTR pszSearchFilter = new OLECHAR[dwLength];
LPOLESTR szFilter; // Filter for finding specific users.
// NULL returns all user objects.
LPOLESTR *pszPropertiesToReturn;
DWORD dwLength = MAX_PATH * 2;
wsnprintf(pszSearchFilter, dwLength, L"(&(objectClass=user)(objectCategory=person)%s)",szFilter);
I need a help in finding the suitable header file for the wsnprintf() signature.

Hi!
I have a mdb file created by Access 2002 and I am using ado. (and no mfc)
pSet is my recordet pointer. I connect and open the database like this:
<br />
try{<br />
CREATEiNSTANCE(pDb,Connection);<br />
pDb->ConnectionString = L"driver={sql server};SERVER=(local);Database=pubs;" L"UID=sa; PWD=;"; <br />
pDb->ConnectionString = constr;<br />
pDb->Open( "", "", "", -1 );<br />
CREATEiNSTANCE(pSet,Recordset) <br />
pSet->PutRefActiveConnection( pDb );<br />
pSet->Open("SELECT TEST1 FROM TABLE1", constr, adOpenDynamic, adLockBatchOptimistic, -1);<br />
pSet->MoveFirst();<br />
} <br />
catch(_com_error &e)<br />
{<br />
......<br />
}<br />
This works fine until I call MoveLast or MovePrevious. When I call these it gives an abnormal program termination error. On the net I found some information about it and it tells me that MovePrevious and MoveLast will generate and error if there is no support for bookmarks or no support for backward cursors... I think I managed to integrate backward cursors by specifying adOpenDynamic ( right???). How can I integrate bookmarks or check if my database supports bookmarks? 
Thank you very much for your future answers!
Well... I am a beginner ...

I would like some help in implementing a very large integer for the RSA.
|
|
|
|
|
Here's a library which'll handle it for you: GMP[^]. I've used it myself to successfully implement the encode and decode functions of RSA. I also wrote a (very inefficient) keygenerator for RSA with it as well. It works.

Has anyone found a way to delete email off servers that works?
P.J. shows the following in CPop3Connection:
BOOL CPop3Connection::Delete(int nMsg)
{
BOOL bSuccess = TRUE;
//Must be connected to perform a delete
ASSERT(m_bConnected);
//if we haven't executed the LIST command then do it now
if (!m_bListRetrieved)
bSuccess = List();
//Handle the error if necessary
if (!bSuccess)
return FALSE;
//Send the DELE command along with the message ID
char sBuf[20];
sprintf(sBuf, "DELE %d\r\n", nMsg);
int nCmdLength = strlen(sBuf);
if (!m_Pop.Send(sBuf, nCmdLength))
{
TRACE(_T("CPop3Connection::Delete, Failed to send the DELE command to the POP3 server\n"));
return FALSE;
}
return ReadCommandResponse();
}
It does NOT clear the server of the message.
I emailed the folks at apache and they suggested their is a know issue, and to send along a flush.
So....
// Send the flush command to server
char sbuff_f[20];
sprintf(sBuf_f, "FLUSH\r\n");
int nCmdLength = strlen(sBuf_f);
if (!m_Pop.Send(sBuf_f, nCmdLength))
No joy after flush.
Please help!
Best Wishes and Happy Holiday's,
