I've tried both WM_NCMBUTTONDOWN and WM_NCLBUTTONDOWN, but neither works.

Hi
You need to lock the mouse cursor to your windows.
During this lock all messages will be parsed by you.

In the close function you can relase the mouse

If you use MFC you can call CWnd::SetCapture like this

<br />
BOOL CMyDlg::OnInitDialog()<br />
{<br />
...<br />
// Capture the mouse<br />
this->SetCapture();<br />
...<br />
}<br />

You then need to capture the WM_LBUTTONUP message since the whole desktop is now client arrea you will get this message then simply check whether the point is your window rectangle or not.

<br />
void CdlgcloseDlg::OnLButtonUp(UINT nFlags, CPoint point)<br />
{<br />
  CRect rtWnd;<br />
  GetWindowRect(&rtWnd);<br />
  ScreenToClient(&rtWnd);<br />
  <br />
  if(!rtWnd.PtInRect(point))<br />
  {<br />
    // Release the mouse<br />
    ReleaseCapture();<br />
    //  Invoke WM_QUIT<br />
    PostQuitMessage(0);  <br />
  } <br />
  <br />
  CDialog::OnLButtonUp(nFlags, point);<br />
}<br />

If you use the win32 API the funtions are:

<br />
SetCapture(HWND hWnd);<br />
ReleaseCapture();<br />

Hope that this is what you needed

hi,

where do you capture the WM_LBUTTONUP (or DOWN) messages, in the messageloop of the dialog or in one of the child controls.

If you capture/process it in the messageloop of the dialog it should, work Confused | :confused:

I tried it with a small sample app and didn't get any problems

Does anyone know how to get the amount of disk space the system has reserved for Temporary Internet Files? I know you can change this setting in IE. I need to get it programatically.

Here is an image of the Settings dialog in IE that shows the variable: http://img356.imageshack.us/my.php?image=tifdiskspace6rv.jpg

WriteFile take a long time, Why?

I create a big file, using the SetEndofFile, then i Seek the filepointer and write some data in it, but i found the func WriteFile take a long time, Why?

HANDLE hFile = CreateFile(_T("D:\\writetest.dat"),
GENERIC_WRITE,
FILE_SHARE_WRITE|FILE_SHARE_READ,
NULL,
CREATE_ALWAYS,
FILE_ATTRIBUTE_NORMAL|FILE_FLAG_RANDOM_ACCESS,
NULL);

LARGE_INTEGER llPos, llNew;
llPos.QuadPart = 2000*1024;
llPos.QuadPart *= 1024;
SetFilePointerEx(hFile, llPos, &llNew, FILE_BEGIN);
SetEndOfFile(hFile);

llPos.QuadPart = 1800*1024;
llPos.QuadPart *= 1024;
SetFilePointerEx(hFile, llPos, &llNew, FILE_BEGIN);

DWORD dwBytes = 256 * 1024;
BYTE * pBuffer = new BYTE[dwBytes];
DWORD dwBytesWritten;
DWORD dwBegin = GetTickCount();

WriteFile(hFile, pBuffer, dwBytes, &dwBytesWritten, NULL);

DWORD dwTime = GetTickCount() - dwBegin;
CString strTime;
strTime.Format(_T("Time: %d"), dwTime);
AfxMessageBox(strTime);

delete []pBuffer;
CloseHandle(hFile);

Thats' a big file alright. So it will take it's time to handle.

But you might speed it up by replacing FILE_FLAG_RANDOM_ACCESS with FILE_FLAG_SEQUENTIAL_SCAN or FILE_FLAG_WRITE_THROUGH.

I suspect FILE_FLAG_SEQUENTIAL_SCAN will give the most performance gain. (You aren't really doing random access of the file, just sequential writing).

MessageBox used in C++ .NET

Tom Sapp3-Nov-05 16:35

3-Nov-05 16:35

I am trying to use MessageBox in .NET but I keep getting an error.

Code I am using:

MessageBox( NULL, "This is the text", "MessageBox", MB_OK );

Error I am recieving:

error C2065: 'MB_OK' : undeclared identifier

I get this error, however, when I mouse over MB_OK it gives me a tooltip saying "#define MB_OK 0x00000000L". Anyone know what I can use in it's place or how to fix this?

Thanks,

Oh, this is a managed C++ message box. In that case - MessageBox has no constructors. Instead, it has a static method called Show. In that case, you need to pass in the managed enum, you can't pass in a MB value or a number.
