During Creation Override OnInitDialog function and
add this ModifyStyle(0, WS_MAXIMIZE); to your code.

Like

CDialog::OnInitDialog();
ModifyStyle(0, WS_MAXIMIZE);
}

Copy to clipboard problem.

I need to copy some string to the clipboard.
This is the code I use:

handle = GlobalAlloc(GMEM_MOVEABLE,text.GetLength()+1);
if (handle)
{
    if (OpenClipboard(hWnd) && EmptyClipboard() )
    {
        out = (char*)GlobalLock(handle);
                    // this fails sometimes (out=NULL)

My code sometimes fail at out = (char*)GlobalLock(handle);
GlobalLock returns NULL and GetLastError() = 6 (invalid handle).

Any ideas why ?
Is there more reliable code for copying to clipboard ?

Thank you!

I ran across the following code in one of our projects - not sure if it will help you or not

<br />
HGLOBAL hData = 0;<br />
// open memory file<br />
CSharedFile clipb (GMEM_MOVEABLE|GMEM_DDESHARE|GMEM_ZEROINIT);<br />
clipb.Write(cstrString, cstrString.GetLength()*sizeof(TCHAR));<br />
clipb.Write(_T("\0"), sizeof(TCHAR));<br />
hData = clipb.Detach();<br />
// Now, hand over memory block to clipboard<br />
if (hData)<br />
{<br />
   VERIFY(OpenClipboard());<br />
   SetClipboardData(CF_TEXT, hData);<br />
   VERIFY(CloseClipboard());<br />
}<br />

shared data segment

Hi all,

I have two dll
1)DLLHook- global hook dll
2)BHODLL- a BHO dll

and a server application
3) DlgApp

in DLL hook i have
#pragma data_seg(".shared")
map<_tstring,_tstring> g_map;
// Other objects
##pragma comment(linker, "/section:.shared,RWS")

In DlgAPP, I am inserting some values in map.
Now I have to use these value in BHODLL.

While I debug the BHO, i do not see and values in the map. As per my understanding the global data section will be avaible in all the process after installing hook.so the map should be avaible in BHO code.

Is these possible? or I am doing something wrong?

Thanks in advance.
Regards
Abhi Lahare

That can not work. This is because a map is allocates memory on the heap which does not work using shared data segments because the heap is not part of the shared data segment. You need to use a structure that at compile time allocates the maximum storage necessary and does this in the shared data segment.

Or create a memory mapped file and don't use a shared data segment at all...

Any sufficiently gross incompetence is nearly indistinguishable from malice.

Hi,
I want to create vertical tab pages, with bitmap images on the title of each property page, using CPropertyPage. Can anyone tell me how to do this? I tried to paint on the title of the page, but do not know from which place should I do this.

By 'title' do you mean the tab that you click on to select the page?

If so then you can do this from the CPropertySheet class. Use CPropertySheet::GetTabControl() to get a pointer to the tab control, you can then use the CTabCtrl member functions to do what you want, including custom drawing the tabs.

You may be right
I may be crazy

I think this is a typo in your post but this is objbase.h

Anyway, post the line of code where you call it, it's probably a typo.

Inside the a thread

{
//CoInitialize(NULL);
CoInitializeEx(NULL,COINIT_MULTITHREADED);

m_TimeLock.Lock();
m_timeLastAction = CTime::GetCurrentTime();
m_TimeLock.Unlock();

// Attach the socket handle to a CSocket object.
// This makes sure that the socket notifications are sent to this thread.
m_ClientSocket.Attach(m_hSocket);
