The problem with doing that is doesn't it stop the code from being able to be compiled in both ansi and UNICODE since i would have wcscpy() in my code? 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

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.

Or simply use _tcscpy, which is already defined with the same purpose Smile | :)

Hi,

sFontDetails.FaceName is an array of character, you cannot simply do this
sFontDetails.FaceName = _T("Times New Roman");

So use _tcscpy() it will work fine for you

Thanks everyone, tried _tscpy and it worked like a charm:

_tcscpy(sFontDetails.FaceName, _T("Times New Roman")); //no problem Laugh | :laugh:

Learning C++ having done C# is clearly giving me some problems. Anyway thanks again to all who helped...

First you have to make some memory dcs. I think you can!

Then load the images to that dcs with LoadImage(...).

You can then use those dcs anytime you want to show the images.

OK?

Use the CImageList class or create your own array of CBitmaps.

This assumes you are using MFC.

How to specify a sound card in windows media player

I want to specify a sound card for windows media player but keep the windows default sound card unchanged (i.e., windows use another sound card). By the use of DirectSound, I can enumerate all sound cards in my system.

So, after I obtained the GUID of the sound cards, how can I specify a GUID for the windows media player? Also, how can i specify another GUID for the system as its default sound card?

Thanks for your kindness help!!!

Linking an object with Win32 API

Hi I will link an object of C module with a simple Win32 console application,
but became link errors. For example i have written a "void SomeFunc()" function in C module and declare it in testMain.cpp(Win32 API cpp module)as:
extern void SomeFunct(void);.
When i link this object, the result is:
1- SomeObject.obj : error LNK2005: _SomeFunc already defined in SomeObject.obj
2- testMain.obj : error LNK2001: unresolved external symbol "void __cdecl SomeFunc(void)" (?SomeFunc@@YAXXZ)
3- Debug/testMain.exe : fatal error LNK1120: 1 unresolved externals
Therefore, i try to declare it as:
extern "C" void SomeFunc(void);
When i link this object, the result is:
1- SomeObject.obj : error LNK2005: _SomeFunc already defined in SomeObject.obj
2- Debug/testMain.exe : fatal error LNK1169: one or more multiply defined symbols found

I don't know why? I will be thankful, when everybody can help me.
Best regards, Alireza

You seem to be including SomeObject.obj twice, most likely from diferent locations.

Hi,

maybe you could read forward and then turn your buffer...

Hi,

the most easiest way to do this is:

#include <string>
#include <algorithm>

using namespace std;

string buffer = "hello world";

reverse(buffer.begin(), buffer.end());

// now buffer is "dlrow olleh"
