Hi Jorgen - thanks for the reply. I found my problem just after I made the posting (typical, eh !!) - I needed to select the tick boxes for OLE Automation and OLE Controls when generating the project using AppWizard - it doesn't seem to have included COInitialize() in my source files, but it's got me over the problem, until the next one pops up ...... ! Thanks again !;)

ShellExecute problem

I finally settled on this but am still uneasy.

HINSTANCE res = ShellExecute(NULL,"Open", helpFile, "","E:\\", SW_SHOWNORMAL);

int r = (int)res;

if(r <=32)ShellExecute(NULL,"Open", helpFile, "","C:\\", SW_SHOWNORMAL);

I imagine all I need in the 5th paramtere is the drive letter where the explorer exe is stored. My assumption that its either in E or C is dangerous. How should I handle this dilemma?
Thanks,

Just pass NULL for the starting directory, that is unimportant when you're running IE to show a web page

Setting File Attributes

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++)
			{
				// get the track folder name
				sInstalledTrackDir = pTracksINI->GetTrack(i)->GetTrackDir();

				// make a fully qualified path
				sInstalledFullPath.Format("%stracks\\%s", m_sSimPath, sInstalledTrackDir);

				// see if it's in the trackset
				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
		{
			// pTracksINI is NULL - not an error
		}
	}
	else
	{
		// user doesn't want to play with tracksets - not an error
	}
}

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 )
    // handle error...
  else
    {
    dwAttrs &= ~(FILE_ATTRIBUTE_NORMAL | FILE_ATTRIBUTE_HIDDEN);
    dwAttrs |= dwDesiredAttrib;
    BOOL bResult = SetFileAttributes ( sInstalledFullPath, dwAttrs );
    }

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

Your window needs to have the WS_MAXIMIZEBOX or WS_MINIMIZEBOX style for those items to be on the menu.

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.

WSANO_DATA- WHAT does this mean?

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.

Problems by catching outlook events

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 ?

wsnprintf() method .h file needed ..

derik_konark29-Nov-03 23:52

29-Nov-03 23:52

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 Blush | :O
