For W2k, didn't Microsoft add some (Winsock2?) functions that let you compose your own IP packets, including TCP/UDP headers and all?
Have you tried searching MSDN? I'm pretty sure there was a sample there some time ago of how to form and send your own formed IP packet. If I'm wrong, perhaps it was on another site (e.g. codeguru)?

I have a hard time figuring out where ::HTMLHelp looks for the .chm's specified. Path of caller? current folder? Search path? Further adding to the confusion, there's HKLM\Windows\HTML Help in the registry, which seems to contain filename->full path mappings, but only for MS Office help.
TIA

Hi,
Take a look at

Well, is not right just what you were looking for ( is on a View), but maybe you can somehow fake it or make something..
Good luck !

Hi,
I have 2 threads & 2 events.In one thread i will set one event & 2nd thread will be waiting for that event.
This logic works fine if i put a messagebox in the 2nd thread,otherwise it hangs.
Any idea?
|
|
|
|
|
Could you post some code showing the problem? The explanation sheds little light (to my eyes) about what's going on.

Ok, There is a main thread(application thread) & i have created another thread using _beginthread() function.
Also i have 2 events created as below in the main thread.
CallBackEventHandle= CreateEvent( NULL,TRUE,FALSE,NULL);
ImageEventHandle= CreateEvent( NULL,TRUE,TRUE,NULL);
In my thread function i will be waiting for ImageEventHandle event.there it hangs,but it works fine if i put a messagebox in the thread function.
could you pl help me solve this??

Sounds like you are trying to send a message to something in the secondary thread but don't have any type of message loop. Adding the message box creates a temporary message loop.

I do have a message loop.Adding a message box creates a temporary message loop,right.So i replaced the messagebox with a message loop,but it hangs.
Could you pl help me...

The third parameter to CreateEvent is whether the event is initially signalled. If you are trying to wait for ImageEventHandle, it won't since it's already signalled.

Anyone knows how to retreive/store an image in a MDB file? I'm using CByteArray and it does not work! I know there's an article on CP that is using CLongBinary but it does not suit my needs (it uses a tmp file, I need an HBITMAP).
HBITMAP CdbCieSet::GetLogo()
{
CByteArray Array;
Array.Copy( m_logo );
if( Array.GetSize() <= 0 )
{
return NULL;
}
// the header of BLOB is OLE stuff like "Paint Brush Application" .... ecc..
// the len is 78 byte ( I do not know for other headers )
int HeaderLen = 78 + sizeof(BITMAPFILEHEADER);
Array.RemoveAt( 0, HeaderLen ); // I cut all Headers
// some BMP information
BITMAPINFOHEADER &bmiHeader = *(LPBITMAPINFOHEADER)Array.GetData() ;
BITMAPINFO &bmInfo = *(LPBITMAPINFO)Array.GetData() ;
// If bmiHeader.biClrUsed is zero we have to infer the number
// of colors from the number of bits used to specify it.
int nColors = bmiHeader.biClrUsed ? bmiHeader.biClrUsed : 1 << bmiHeader.biBitCount;
LPVOID lpDIBBits;
if( bmInfo.bmiHeader.biBitCount > 8 )
{
lpDIBBits = (LPVOID)((LPDWORD)(bmInfo.bmiColors + bmInfo.bmiHeader.biClrUsed) +
((bmInfo.bmiHeader.biCompression == BI_BITFIELDS) ? 3 : 0));
}
else
{
lpDIBBits = (LPVOID)(bmInfo.bmiColors + nColors);
}
CClientDC dc(NULL);
HBITMAP hBmp = CreateDIBitmap( dc.m_hDC, // handle to device context
&bmiHeader, // pointer to bitmap size and format data
CBM_INIT, // initialization flag
lpDIBBits, // pointer to initialization data
&bmInfo, // pointer to bitmap color-format data
DIB_RGB_COLORS); // color-data usage
Array.RemoveAll(); //Release Memory
return hBmp;
}
BOOL CdbCieSet::SetLogo(CString szFileName)
{
CByteArray BlobFile;
CFile aFile(szFileName,CFile::modeRead);
BlobFile.SetSize(aFile.GetLength());
aFile.Read(BlobFile.GetData(),aFile.GetLength());
aFile.Close();
m_logo.Copy(BlobFile);
SetFieldDirty(&m_logo);
SetFieldNull(&m_logo,FALSE);
return TRUE;
}
Thanks!

I want to create a DLL which will be used in an EXE. In the DLL, I want to export some simple classes, but they use MFC's CString as memebers. What kind of DLL should I create, how to export them, and import them. Should I use AFX_EXT_CLASS instead ? However, I'm planning remove MFC dependency by using some kind of CString clone in the future.
I tried use __declspec(dllexport) and __declspec(dllimport) with created the DLL as regular MFC DLL. However, in using it, in deleting the heap allocated instances, it has memory violation.
Can anyone tell me the hints ?

Use the multithreaded DLL version of the C run-time library in both the DLL and the EXE. This will ensure only one heap is used globally.

I checked both the EXE and the DLL are using Debug Multithreaded DLL.

You must create a MFC Extension Dll and declare your classes with the AFX_EXT_CLASSES like this:
class AFX_EXT_CLASS CMyClass
{
....
};

I just suddenly started getting this. It is happening in multiple projects.... not *all*. Is that a MFC dll? One common thread seems to be that all the ones that won't compile use MFC.
The debug version is the only one that gives this error. Release works fine...
Any ideas??
Thanks

Ehh, "foo"? No, it's an error (a terminal bug) in the linker.
Reading the MS NG microsoft.public.dotnet.languages.vc I can only come to the conclusion that this release should never have happened. It contains so many (terminal) bugs that it's apparent their so-called QA was on vacation this year also.
For a more authorative answer you should try to post this to that NG (and watch the "maybe fixed in the next version" comment you'll get from MS).

Yup, you have hit an internal bug in the linker. Try a rebuild all.
That MSPDB70.DLL is probably a common DLL they use to support the .PDB debug files.

I do some draw action:
void CMyView::OnPaint()
{
CPaintDC dc(this); // device context for painting
if( m_bDraw == FALSE )
return;
/**/
CDC* pDC = GetDC();
CDC cacheDC;
VERIFY( cacheDC.CreateCompatibleDC( pDC ));
if( m_pBitmap == NULL )
{
m_pBitmap = new CBitmap;
VERIFY( m_pBitmap->CreateCompatibleBitmap( pDC, m_ClientRect.Width(), m_ClientRect.Height() ) );
}
CBitmap* pOldBmp = cacheDC.SelectObject( m_pBitmap );
//Draw background
CRect rect( m_ClientRect );
cacheDC.FillSolidRect( &rect, RGB(255, 255, 255) );
//cacheDC.Rectangle( rect );
cacheDC.Draw3dRect( &rect, RGB( 0, 0, 0 ), RGB( 255, 255, 255 ) );
//!! Some draw actions here, use cacheDC
pDC->BitBlt( m_ClientRect.left,
m_ClientRect.top,
m_ClientRect.Width(),
m_ClientRect.Height(),
&cacheDC, 0, 0, SRCCOPY );
cacheDC.SelectObject( pOldBmp );
cacheDC.DeleteDC();
}
When I open tha "TaskManager", I notice that the memory usage of My app is increase, what's wrong with my draw method?
I'm amumu, and you?

You are not deleting your m_pBitmap after you are done with it. Your code should look like this:
cacheDC.SelectObject( pOldBmp );
cacheDC.DeleteDC();
m_pBitmap->DeleteObject();
