Is that 'grab bitmap' same meaning with 'extract pixel data' from video capture window? Microsoft directX 9.0 sdk has provided such grab bitmap tool. How can i utilize it?

Maybe writing a MACRO for MSWord (or OpenOffice!) is easier than deciphering the proprietary DOC-Format?

You can't read the content of the ms document as it is binary file.
You can read from one doc and write to another doc by using binary files(i.e. open files in binary mode).

As far as I know, the system doesn't send any notification upon login. But, upon logoff, it sends.
Could u tell me, why this concept is needed?

I'm having a problem sending a message from one window to another in my (Win32) application. A little background:
1) It's a dialog based app
2) It consists of a tab control and several child window dialogs
I want to send the text of an edit control from one tab/child window to another tab/child window's list box using:
SendMessage(hwnd, LB_ADDSTRING, 0, (LPARAM) szString);
However I can not get them to communicate.
I can't figure this out (never attempted it before). I have a single function handling all messages of each child window of the tab control. Everything works great as long as I'm updating the window/tab in view.
Can anyone point me in the right direction? Thanks in advance.

You cannot do that with a string. The string is in the memory of your process, all that you are sending is the address, which the second process will not be able to read. To send a string send the WM_COPYDATA message instead. But this will not allow you to add it to a listbox like you are trying.

He doesn't mention two windows from two processes here.

Make sure your message handler is prototyped as follows:
in the header file:
afx_msg LRESULT OnHandleMyMessage(WPARAM wParam, LPARAM lParam);
and in the cpp file:
BEGIN_MESSAGE_MAP(CMyClass, CDialog)
ON_MESSAGE(LB_ADDSTRING, OnHandleMyMessage)
END_MESSAGE_MAP()
LRESULT CMyClass::OnHandleMyMessage(WPARAM wParam, LPARAM lParam)
{
return 1L;
}
Also, you should call PostMessage unless you need to wait for the message handler to return.

Thanks for the reply. I'm quite new at coding and can't quite decipher what you provided, but are you suggesting I subclass the control?
|
|
|
|

He means, make sure you have correctly configured the message handler. But this is only valid if you are using MFC.
|
|
|
|
|
I see. I'm using Win32. Is there a workaround for this?
|
|
|
|
|
Not familiar with Win32, If you can, add something like the following:
BOOL MyDialog::PreTranslateMessage(MSG* pMsg)
{
// catch any WM_USER messages
if (pMsg->message == WM_USER)
{
// see if it's your message
if (pMsg->wParam == LB_ADDSTRING)
{
... process the message ....
.....

What value does this function returns ?
I assume hwnd is handle to target list box.

CMyListCtrl derives from CListCtrl. In CMyListCtrl, I must decide how to subclass CHeaderCtrl:
<br />
void CMyListCtrl::PreSubclassWindow()<br />
{<br />
CListCtrl::PreSubclassWindow();<br />
CHeaderCtrl* pHeaderCtrl = CListCtrl::GetHeaderCtrl();<br />
if (pHeaderCtrl && pHeaderCtrl->GetSafeHwnd())<br />
m_HeaderCtrl.SubclassWindow(pHeaderCtrl->GetSafeHwnd());<br />
}<br />
Everything seems good, but when CMyListCtrl is dynamic created, or created without visible syle, the pHeaderCtrl returned from CListCtrl::GetHeaderCtrl() is null,so subclass CHeaderCtrl failed!
now, I solved the problem, but I don't satisfied.
<br />
void CMyListCtrl::OnShowWindow(BOOL bShow, UINT nStatus) <br />
{<br />
CListCtrl::OnShowWindow(bShow, nStatus);<br />
<br />
if (bShow && !m_HeaderCtrl.GetSafeHwnd())<br />
{<br />
CHeaderCtrl* pHeaderCtrl = CListCtrl::GetHeaderCtrl();<br />
if (pHeaderCtrl && pHeaderCtrl->GetSafeHwnd())<br />
m_HeaderCtrl.SubclassWindow(pHeaderCtrl->GetSafeHwnd());<br />
}<br />
}<br />
Is there any other better resolvents?
thanks
best regards

How about in the OnCreate for the CListCtrl.
That way, you get to subclass even if the list control window is never shown, if that matters or not.
From MSDN:
The CWnd object receives this call after the window is created but before it becomes visible. OnCreate is called before the Create or CreateEx member function returns.
Override this member function to perform any needed initialization of a derived class.
The CREATESTRUCT structure contains copies of the parameters used to create the window.
