Yes you are right  I have confirmed that it is the drawing part of OnNcPaint that is stopping the visual style. Since I do my drawing after the default window processing completes, Windows must work out that I will be calling DrawFrameControl in the future and then render using the old Windows 2000 style.
I think all I have to do now is replace DrawFrameControl with some theme based drawing when running on XP. I have just added to code to load the uxtheme.dll library and get pointers to theme functions I need to call. I think I just need to do the following with appropriate parameters to draw my icon...
if (uxthemeloaded)
{
pOpenThemeData(...);
pGetThemeBackgroundContentRect(...);
if (pIsThemeBackgroundPartiallyTransparent(...))
{
pDrawThemeParentBackground(...);
}
pDrawThemeBackground(...);
pCloseThemeData(...);
}

U can get the title bar height by taking the difference in the top of the window rect and client rect( do forget to call the ClientToScreen of the client rect ).

Few days back i posted here the same problem.I want to get some answers pls help me.
In the application one keyboard is made by using a dialog with bitmap.Then by pressing the keys in that keyboard the application will get data like numbers,alphabets,enter key...like that.This keyboard have all buttons like the system keyboard.
I have to enter values to dialog edit control through this keys.So i get sample coding..In that they coded in keyboard class like..PostMessage(WM_KEYDOWN,49,0);
and in the corresponding dialog class where the value should entered they coded as
void CFacePlate::OnKeyDown(UINT nChar, UINT nRepCnt, UINT nFlags)
{
case 49:
sSktNumValue += "1";
break;
CDialog::OnKeyDown(nChar, nRepCnt, nFlags);
}
So i debugged the program..When ever the Postmessage function in Keyboard class is executed then the contol is going to OnKeyDown function in Dialog class.How it si going there?
I dont know whats happening there.
I coded like this for my application..but the control is not going to OnkeyDown function..How can i make that?

1.One socket with 2 threads do read/write,is that ok?
2.One socket with 2 threads write to that socket with no lock,could the OS provide the receiver's pack oreded,that is,if thread A and thread B send message to the same socket with no sync protected,for exp A send "AAAA",B send "BBBB",is is possible for the receiver socket recive AAAABBBB(ordered) or ABAABAB(disorederd).
3.If using WSASend api to send a buf to several sockets,can we simply use a loop to send like following examples
WSABUF buf;
buf.buf = "test";
buf.len = 4;
Socket list[someNum];
for(i = 0;i++;i< someNum)
{
WSASend(list[0],&buf,1,...);//here we keeping use the same buf!!
}
if its not so correct,is there any good solutions?
Best regards!

Hello everyone!
I still don't quite get how C works... I always get weird, and I mean weird errors, like this one:
I have a char* string. It's a filename. If I printf() it, it gives me "x5" or other characters that don't have anything to do with it. But if I open the file, it opens correctly, and I can even display a string on the file...
Why is this? Is there a tutorial or something that explains this kind of stuff? Thanks!

I need some help converting between TCHAR strings and ASCII strings. (I understand that the actual type for TCHAR is decided by the compiler switches.) In this case, TCHAR is UNICODE. But I have a char* string passed into my function that I need to deal with. My questions:
What's the best way to convert the char* string (array) to TCHAR? I'm doing it one char at a time in a loop, but I am hoping for something more elegant.
How do I handle the ASCII end of string in TCHAR? For example, in one section I need to loop through the characters in the TCHAR string. I want to stop if I hit a new line from the char* string. That's easy in an ASCII string, but in UNICODE... well it's probably just as easy if you know what to look for!  Should I be looking for TWO TCHAR characters (0xA and 0x0)? or something else?
Thank you!

Place the macro USES_CONVERSION at the beginning of your function. You then have access to all of the string conversion macros. You can convert between any of ACSII (A), OLE (OLE), WIDE (W)and TCHAR (T). To convert ASCII to TCHAR do the following.
LPSTR *lpSrc;
LPTSTR *lpDest = A2T(lpSrc);
Similarly T2A, A2W, W2A, A2OLE, etc can be used. You can also put a C after the 2 to get a const string returned.
The good thing about these macros is that if you build the application with _MBCS defined, TCHAR is the same as ASCII so the A2T macros becomes nothing. If you build with _UNICODE defined then it will allocate a buffer and covert to Unicode for you. The memory is allocated on the stack with _alloca, so you can't keep the converted string after the function returns without taking a proper copy of it first. Also don't use inside a loop because it could allocate a lot of memory if the loop iteration is large.

If you use the newer ATL7 conversion macros then you do not have to use USES_CONVERSION and you can safely use the conversion macros inside a loop.

Thanks, this works fine. But I am wondering how the macros work. I followed the code and see that it ultimately ends up at defs for MultiByteToWideChar and others. But of course the code is not shown. So I wonder if this is implemented as just a big lookup table or if there is some better way to approach this.
Obviously this question has become somewhat academic at this point. My initial problem is resolved. But I am just thinking about how I would have implemented this and I don't see a better way than using a big lookup. That seems too clumsy.

An alternative to using the ATL macros is to use the _bstr_t class. It has constructors that take both ASCII and WIDE character sets, and have overloaded operators for both char* and wchar_t*. It will end up calling the same functions in the end (the MultiByteToWide, etc.) but it easier to read and debug since it isn't a macro.
