Hi All
I am converting my non-unicode project to unicode , in this case when i compiling my code i get errors where char data type is used, so does it means that i can not use char data type in unicode? Is it necessary to convert all char. variables to wchar_t or TCHAR variables.

Thank you

Yes, it depends on what you plan to do with a char in a UNICODE build, every(almost all) WIN32 api function has two variants A and W (e.g. SetWindowTextA and SetWindowTextW) xxxW version is called if unicode is defined other wise xxxA if you pass char to xxxW then it will not compile, keeping that in mind if you want to store an 8 bit value and check its individual bits there is nothing stopping you from doing that in a UNICODE build IMHO.

If you think you can than you can, if you think you can't you are right.

You'll need to use wchar_t or TCHAR instead.

This is a problem which i have been facing for a long time.
Now i found a new thing in it (a step ahead) that i am getting an error below....

BOOL CWnd::DestroyWindow()
{
 if (m_hWnd == NULL)
   return FALSE;

 CHandleMap* pMap = afxMapHWND();
 ASSERT(pMap != NULL);
 CWnd* pWnd = (CWnd*)pMap->LookupPermanent(m_hWnd);
#ifdef _DEBUG
 HWND hWndOrig = m_hWnd;
#endif

#ifdef _AFX_NO_OCC_SUPPORT
 BOOL bResult = ::DestroyWindow(m_hWnd);
#else //_AFX_NO_OCC_SUPPORT
 BOOL bResult;
 if (m_pCtrlSite == NULL)
  bResult = ::DestroyWindow(m_hWnd);
 else
  bResult = m_pCtrlSite->DestroyControl();
#endif //_AFX_NO_OCC_SUPPORT
	
 // Note that 'this' may have been deleted at this point,
 //  (but only if pWnd != NULL)
 if (pWnd != NULL)
 {
  // Should have been detached by OnNcDestroy
#ifdef _DEBUG
  ASSERT(pMap->LookupPermanent(hWndOrig) == NULL);// <big>HERE IT FAILED</big>
#endif
 }
 else
 {
#ifdef _DEBUG
  ASSERT(m_hWnd == hWndOrig);
#endif
  // Detach after DestroyWindow called just in case
  Detach();
 }
 return bResult;
}

What does it mean and What i have to do?

Here i found a similar question in codeguru forum [^]. But did not understand the answer given by Jonny Poet.
He said

open the 'Calling list Viewer' ( I dont know the english exact word),
where you can see all the calls which have been done to get to this point.
In that list you look backword this list to find the next point where there is
a name of a function of your program This was then obviously the point
where from it comes.Before that you set your breakpoint.And then you will se why
this happens.

what does he mean by the 'Calling list Viewer' and where can i get that?

How are you creating the CWnd object on stack or via new operator?

How to invoke MSDN from an application?

I have an application which need to invoke MSDN (local) and providing it an argument, such that the effect is the same as if we manually opened MSDN and looked up the "argument" in MSDN.

How do I achieve this?

Hello,
here is the format of my date string:

Thu, 13 Oct 2005 08:31:51 GMT

I try to do this like:

<code>
CString csDate = L"Thu, 13 Oct 2005 08:31:51 GMT";
COleDateTime oleTime;
// here i need help :(
</code>

i know how to parse that string manualy, but i hope that there is an internal function
to do this! Confused | :confused:

this should be new format of them:

2005-10-13

I just need the date from this string, not the time and other text likt "Thu" etc.

regards

Best XML Config class ?

I'm looking for a small and fast XMLConfig class in C++ that I can use for program settings. It needs to support multiple instances of a program which all use the same settings file. Since all instances can possibly read and write to the config file at the same time, it needs to handle this instance.

There are lots of different XMLConfig classes available, and I'm wondering which one would best suit my needs ?

tinyXML and CMarkup i have used both in production code, use CMarkup if you require a small footprint.. tinyXML is more complete.

Sorry, I'm a little bit confused here. You probably meant that you want to open and compile your project with VC2005, right ?

Well, it depends of the type of project (and also depends of the code itself). Normally, if you open your .dsw file with VC2005, it will start a conversion wizard that will do the conversion of the project for you. Normally it should work correctly. If you still have problems, tell us where exactly the problems are.

Depends on how good your code was. It's very possible that portions of your code won't compile, or at least give new warnings.

But, in the first instance, you can open and build it via the conversion wizard, which is automatic, just open the DSW
