Dody_DK29-Aug-05 23:29 Dody_DK 29-Aug-05 23:29  I know how to import the .lib files into vc++, but how to use them? if I import MSN Messengers .lib files, then I can see its classes like DMessengerEvents::OnSignin; but when I creat a button and put the code in Onclick, then nothing happen... any ideas about this? Grouping windows Nishad S29-Aug-05 23:27 Nishad S 29-Aug-05 23:27  Hello, I need to make my window to be the background window of some of currently running windows (eg. all notepad windows). When the user activates the notepad (one of the running notepad or opening a new one), my application should come to top, but behind all the notepads. Similarly if the user activates my window, the same thing should be happened. In other words, my window needs to be the background of all the notepads. Does anybody have an idea to solve this problem?

UNICODE woes TheGroinalRampager29-Aug-05 23:15 TheGroinalRampager 29-Aug-05 23:15  In my attempts to make my program as versatile as possible I followed all the advice given about using TCHAR's and the _T macro so that my code could be compiled in both the ansi standard and the UNICODE standard. However i have run into a wall now which suggests i am not understanding something..... in this line: sFontDetails.FaceName = _T("Times New Roman"); i get the error: error C2440: '=' : cannot convert from 'const unsigned short [16]' to 'WCHAR [32]' I was under the impression that the _T macro when used with a string literal should be automatically converted to the WCHAR[] type or the normal char[] type depending on whether i have the line #define UNICODE in my program or not..... what am i missing? Thanks in advance, Ed Bosher Re: UNICODE woes toxcct29-Aug-05 23:25 toxcct 29-Aug-05 23:25  did you defined those two constants : stdafx.h : #define _UNICODE #define UNICODE do it at the beginning of the stdafx.h file...

TOXCCT >>> GEII power [toxcct][VisualCalc] -- modified at 7:32 Tuesday 30th August, 2005 oh..... but still..... TheGroinalRampager30-Aug-05 1:16 TheGroinalRampager 30-Aug-05 1:16  Ok thx didn't know that but still, I have definately declared both the UNICODE macros, if I remove them it says: error C2440: '=' : cannot convert from 'const char [16]' to 'CHAR [32]' instead of (with #define _UNICODE and #define UNICODE): error C2440: '=' : cannot convert from 'const unsigned short [16]' to 'WCHAR [32]' So maybe the question is why is the UNICODE macros turning my string into and unsigned short and not a WCHAR? Re: oh..... but still..... toxcct30-Aug-05 1:20 toxcct 30-Aug-05 1:20  because the operator = () don't copy the contents of the C-style strings but only the addresses of the pointers... does this error occur with strcpy() ? i doubt... you could use strncpy() also if you want to copy not the totality of the string but a part... TOXCCT >>> GEII power [toxcct][VisualCalc] Re: UNICODE woes TheGroinalRampager30-Aug-05 1:01 TheGroinalRampager 30-Aug-05 1:01  Yes it is WCHAR, I have already included the #define UNICODE and #define _UNICODE line, if I hadn't i believe it would have a different error along the lines that _T would not be a declared macro....

I suppose some macros could fix it but i would rather just use the _T macro which is how MSDN says it should work..... thx again though Re: UNICODE woes [edited] toxcct30-Aug-05 1:25 toxcct 30-Aug-05 1:25  hum, yes, but you can now define a macro like this : #if defined(_UNICODE) #define _MBCSCPY wcscpy #else #define _MBCSCPY strcpy #endif now, you can use it just like that : #include <string.h> TCHAR* psz = "Hello"; TCHAR tab[10]; _MBCSCPY(tab, psz); _tcscpy(tab, psz); it will use strcpy() if _UNICODE is not defined, wcscpy() otherwise.

Anyway thanks again to all who helped... loading images in memory a_david12329-Aug-05 23:13 a_david123 29-Aug-05 23:13  Respected all Regards! I am david and have a problem.
