control a downloaded activex control

I have an activeX control that I have tested and signed - however I have discovered
that I can download the control from a web page that is on a different site to the control (.cab)

Is there a way of marking the control so that it cannot be 'borrowed' by another site ?

there's some licensing you can do - for example, the MSHFlexGrid (in Visual Studio etc) is a licensed control - there is a special procedure that must be gone through to use it on a machine that does not have VB or Visual Studio installed. I don't know how to license a control, but I do have experience with this particular control and the hoops we had to do to get it to work. (on a pc that had not had the licensing procedure run, it displays as a blank box)

thanks - I did look at licensing but I couldn't see how it would stop anyone from using the control x-domains - I eventually implemented something via IObjectWithSite - to get the URL that the control was working under and then check to see if the url domain was one I allow access to

How to use Custom Resources

Hi.

My program needs a block of binary data to work. I do not want this binary data in a separate file because it is a) unchanging and b) i want minimal dependancies.

I've created a custom resource in resource editor and put my binary data in there.

I want to get a (BYTE *) pointer to this data at run time. The only method i've found of doing that up to now is this:

BYTE *p_SREData;
HGLOBAL hGlobal; HRSRC hRSrc;

hRSrc=FindResource(NULL, MAKEINTRESOURCE(IDR_DATA1),RT_RCDATA);
hGlobal=LoadResource(NULL, hRSrc);
p_SREData=(BYTE *) LockResource(hGlobal);

Whilst this works, surely there's a better, simpler way of getting the data?

And MSDN for LockResource states that the system frees allocated memory upon program termination, but you can free the memory manually when you no longer need it by calling one of the functions. But it's not obvious which function to use for a custom binary resource. Any ideas?

Sorry to dissapoint you all with my lack of a witty or poignant signature.

Actually there is a faster way to do this. If you define your custom resource as for example
a "BINARY" data (Insert Resource->Custom (button) ->"BINARY" without quotes).
I always defined custom resource as binary anyway but give it the name you want...
Fastest way to get the data in my opinion is this:
// LPCTSTR lpszName = MAKEINTRESOURCE( idr_your_resource_id );
// LPCTSTR lpszType = _T("BINARY");
// HINSTANCE hRes = AfxGetResourceHandle();

BYTE* GetResourceData(LPCTSTR lpszName, LPCTSTR lpszType, HINSTANCE hRes)
{
   HRSRC res = ::FindResource(hRes, lpszName, lpszType);
   ASSERT( res != NULL);
   BYTE* pBytes = (BYTE*) LockResource(LoadResource(hRes, res ));
   ASSERT( pBytes != NULL);
   return pBytes;
}

Hello everybody!

I have a little problem, help me please!

1. I'm create the listbox with multi-column style
2. I'm set the Width of ListBox (SetColumnWidth)

How can I add string to the second column, third column and etc?

Best regards,

Re: Help with multi-column ListBox

You should use:
BOOL SetItem( int nItem, int nSubItem, UINT nMask, LPCTSTR lpszItem, int nImage, UINT nState, UINT nStateMask, LPARAM lParam );

The nItem is the line and the nSubItem is the column:
SetItem(102,2,0,"Second Colum",0,0,0,0);

Re: Help with multi-column ListBox

But SetItem method is a member of the CListCtrl class and not member CListBox.

I want made multi-column from CListBox!

You can't! use CListCtrl. CListBox has less features than CListCtrl but
a CListCtrl is a bit harder to use.

TrackPopupMenu Fails in Thread

17-Dec-01 1:14

Hi -

VC6 NT4 and Win98

I'm having a problem where TrackPopupMenu() fails and ERR is 0. I make the call inside a worker thread. Why does it fail there with no error? I read somewhere that TrackPopupMenu has its own message pump. Is this true?

Here's some code:

//
// this method works.
// TrackPopupMenu returns 1 and the menu is displayed.
//
void CTestMenusDlg::OnButton1()
{
CMenu *pMenu = new CMenu();
VERIFY(pMenu->CreatePopupMenu());
VERIFY(pMenu->AppendMenu(MF_STRING | MF_ENABLED, 32001, "Test1"));
VERIFY(pMenu->AppendMenu(MF_STRING | MF_ENABLED, 32002, "Test2"));
BOOL bOK = ::TrackPopupMenu(pMenu->m_hMenu,
TPM_LEFTALIGN |TPM_RIGHTBUTTON,
300, 300, 0, this->m_hWnd, NULL);
}

//
// this method will start a thread
//
void CTestMenusDlg::OnButton2()
{
CWinThread *pThread = AfxBeginThread(
PipeThread, this, 0,THREAD_PRIORITY_NORMAL,0,NULL);
}

//
// Runs same code as button1.
// TrackPopupMenu returns 0 and ERR is 0
//
UINT PipeThread(LPVOID lpvParams)
{
ASSERT( NULL != lpvParams );
CTestMenusDlg *pDlg = reinterpret_cast<CTestMenusDlg *>( lpvParams );
CMenu *pMenu = new CMenu();
VERIFY(pMenu->CreatePopupMenu());
VERIFY(pMenu->AppendMenu(MF_STRING | MF_ENABLED, 32001, "Test1"));
VERIFY(pMenu->AppendMenu(MF_STRING | MF_ENABLED, 32002, "Test2"));
BOOL bOK = ::TrackPopupMenu(pMenu->m_hMenu,
TPM_LEFTALIGN | TPM_RIGHTBUTTON,
300, 300, 0, pDlg->m_hWnd, NULL);
DWORD dwErr = ::GetLastError();
return 0;
}

I have a question:
Why you want to create a popup menu from a worker thread?

Re: TrackPopupMenu Fails in Thread

17-Dec-01 8:49

>> Why you want to create a popup menu from a worker thread?

Actually my real code does the opposite of my example. A worker thread gets sent a menu hierarchy via CORBA, creates a bunch of HMENUs and stores them in a table. Later on, when an item in a view is right-clicked, I look up the appropriate HMENU and create a popup.

When I started to debug this thing, I was sure that it was a threading issue and I thought that I couldn't share HMENUs across threads. I wrote a TestMenu app to check this theory out and I somehow flipped it so that the popups were being created inside the worker thread.

I've solved my problem though - a coding error in the worker thread was creating empty menus. Good HMENUs, but just no items. Still, in this instance and in my example code, when TrackPopupMenu was failing, it returns 0 and GetLastError is 0.

If TrackPopupMenu has its own message pump (as someone wrote in another post) and I pass a valid hWnd to TrackPopupMenu, why would it matter though if I called it from a non-UI (worker) thread?

thanks

Hi All,

We are having a requirement in which we need to calculate sunrise and sunset time depending on latitude, longitude and time zone. It would be of great help if you could suggest us any alogrithm to calculate the sunrise and sunset times.

Thanks

If you're only interested in the IP addresses, check Warren Young's Winsock Programmer's FAQ example Getting the Local IP Address. If you're looking for more comprehensive information about the NICs, then SNMP is the way to go, and you might find it interesting having a look at Lee Hamel's article Retrieving NIC information using SNMP queries.

static data member in MFC program

Dave K Dosanjh16-Dec-01 16:28

16-Dec-01 16:28

In my MFC application I had to create a static callback member function. The function works ok, but now I need to declare a static data member.

So I added a static member like so…

class Blah
{
public:
static HRESULT SomeCallback (…);
static int YayIAmStatic;
.
.
.
}

This compiles ok, but when I try to access the static member (from within the static callback or any other regular method) I get the following linker error:

unresolved external symbol "public: static int Blah::YayIAmStatic"

Is this not the appropriate syntax for creating a static member? Please humour a poor newbie – this is my first crack at an MFC program.

Re: static data member in MFC program

Christian Graus16-Dec-01 16:47

16-Dec-01 16:47

To declare a static variable in class Blah, put the statement in the header, as you have, then in the .cpp file put

int Blah::YayIAmStatic;

As it stands, you've told the compiler there is going to be a static int, but you've not created it.
