I think using PostThreadMessage would be better. Also check how the message queue is handled in your target thread.

What is the cause of the exception. I would assume m_pDlg isn't valid at the time it is used.

CWnd* objects are not thread safe, give the thread a copy of the HWND and send a message to that.

What does UM_UPDATEDIALOG equate to? How does the dialog class respond to the posted message? Maybe the pointer is invalid.

I think, some years have 52 weeks while some have 53. Is there a way of using CTime/SPan classes to compute this
|
|
|
|
|
How about do it like that :
COleDateTime ct = COleDateTime( 2003, 12, 31, 23, 59, 59 );
int iNumWeeks = atoi( ct.Format( "%U" ) );

Hi !
please use the <pre> HTML tags (see Formatting bar under your sig when writing a message) to format your code instead of bold. It is far more readable.

I am building a project.I want to write something to registry to save some informatiom.
|
|
|
|
|
Who can give me a sample or a demo?
|
|
|
|

Use RegOpenKey, RegQueryValue, RegCloseKey.
You can look for sample code in MSDN, or you can search Google for a whole lot of sample code
You might also find some code on CP

Here are some code snippets, which you may use :
//////////////////////////////////////////////////////
CString GetFromRegistry( CString csRegKeyString, CString csRegKeyField, CString csDefault )
{
CString csResult = csDefault;
CRegKey* pRK = new CRegKey();
LONG lRegOpen = pRK->Open(HKEY_LOCAL_MACHINE, csRegKeyString);
if(lRegOpen == ERROR_SUCCESS)
{
char cValue[1000];
memset( cValue, 0, sizeof( cValue ) );
DWORD dwSize = sizeof( cValue );
LONG lRegQuery = pRK->QueryValue( &(cValue[0]), csRegKeyField, &dwSize );
if(lRegQuery == ERROR_SUCCESS) csResult = cValue;
}
delete pRK;
pRK = NULL;
return( csResult );
}
//////////////////////////////////////////////////////
BOOL SetInRegistry( CString csRegKeyString, CString csRegKeyField, CString csValue )
{
BOOL bResult = FALSE;
CRegKey* pRK = new CRegKey();
LONG lRegSetValue = pRK->SetValue( HKEY_LOCAL_MACHINE, csRegKeyString, csValue, csRegKeyField );
if(lRegSetValue == ERROR_SUCCESS) bResult = TRUE;
delete pRK;
pRK = NULL;
return( bResult );
}
I think there are a lot of complete classes here at codeguru. Use the code above only as an example how you may do it.
Best regards

Who can tell me how to change the height of CComBox.

Dave:
First thands a lot,SetItemHeight works very well.
But another question is that how can i change the font size of the ccombobox,i created the control in source file instead of in source view control.i put the control on the toolbar instead of on dialog box.
Can you help me further?

Something like:
CFont* pOldFont = m_combo.GetFont();
LOGFONT lf;
memset( &lf, 0, sizeof(LOGFONT) );
pOldFont->GetLogFont( &lf );
CClientDC dc( m_combo );
lf.lfHeight = -MulDiv( PointSize, dc.GetDeviceCaps( LOGPIXELSY ), 72 );
CFont* pNewFont = new CFont();
pNewFont->CreateFontIndirect( &lf );
m_combo->SetFont( pNewFont );

Is it Ok (good practice) to include headers within other header files ?
I have a CTimer Class declared in TimerClass.h and implemented within TimerClass.cpp.
I have a CAnimatedSprite class declared in AnimatedSprite.h and implemented within AnimatedSprite.cpp.
Is it alright for the AnimatedSprite.h to #include "TimerClass.h" and for the AnimatedSprite.h to have as a class member CTimer AnimationTimer; ?
Is there a requirement for the CTimer to be a friend of CAnimatedSprite ?
Responses much appreciated,
Wodger

There is no problem having includes within includes, and they really should be there if the file won't compile without them.
You do not need to make CTimer a friend of CAnimatedSprite just to make it a member variable. You only need a friend class when it needs to access protected/private members of another class.

You should always minimize inclusion of headers in other headers, especially on larger projects as you get unnecessary compiles on the slightest change. Read "Large Scale C++ Design" (I think that is the title) for a very informative and in depth discussion of the many problems here.
Try not to make CTimer a member, but instead use CTimer* then you can forward declare CTimer (eg. class CTimer;) and hide its implimentation from the AnimatedSprite.h file. ie. It only needs to be visible in AnimatedSprite.cpp Read about PIMPL and look at Boost Smart Pointers www.boost.org[^]

Cheers, Thanks and Superb to both of you.
I'm not quite sure what you mean wrt CTimer* (Newbie Alert)
// AnimatedSpriteClass.h
// Doesn't the statement
CTimer* pSpriteTimer;
// require the TimerClass header to create a pointer to one ?
// No: because it is not initialised ?
// AnimatedSpriteClass.cpp
// Then when I define the InitSprite(int x, int y, int CurrentAnimSequence);
// do I initialize the Ctimer pointer to an instance of the CTimer ?
pSpriteTimer = new CTimer;
// will that do the trick ?
// Cheers,
// Wodger
