odd wostringstream problem
Hello,
I thought this would trace the value "10" twice -
wostringstream OldSetting;
wostringstream OldSetting2;
WORD wValue = 10;
int iValue=10;
OldSetting << wValue;
TRACE(OldSetting.str().c_str());
OldSetting2 << iValue;
TRACE(OldSetting2.str().c_str());
but the WORD (or unsigned int) value does not appear. With different values I sometimes get garbage coming out. In this case I got nothing at all.
If I use ostringstream then it works as expected. Is this a bug or have I done something wrong?
This is with Visual Studio 2003.
Thanks.
Peter

Obviously, you can't expect a wchar_t stream to be implicitly converted to char * by calling c_str while still getting meaningful results... If you need to use c_str for some reason then you should stick to char based streams. Also, check teh definitio of TRACE. What kind of strings does it expect?

Thanks - I thought TRACE catered for that but it doesn't. I changed my test to the following code and it works fine now.
wostringstream OldSetting;
wostringstream OldSetting2;
unsigned int wValue = 10;
int iValue=10;
OldSetting << _T("word value is: ") << wValue << _T("\n");
wcout << OldSetting.str().c_str();
OldSetting2 << _T("int value is: ") << iValue << _T("\n");
wcout << OldSetting2.str().c_str();
