Question

I am a kind of new for c++ , while working on the windows CE .net compact application

while trying to write hexa datas to a file

CString dataBlock1;
dataBlock1 = "";

CString temp;
for(int i = 0; i < rLen; i++)
{
temp.Format(L"%02X ",rec[i]);
dataBlock1 += temp;

}

std::ofstream out(file);

I am getting this error can not convert parameter 1 from wchar * to const char*
on while using the below write function to write hexa datas to a file

out.write(myReader.dataBlock1.GetBuffer(),myReader.dataBlock1.GetLength());

how can we convert wchar_* to const char* to make the write function work.

Thanks.

You can use the wcstombs function, reference here.
