Can anyone tell how to convert a widechar string to VARIANT
I have an unsigned char* string , I am converting it to widechar using MultiByteToWideChar.
How to convert it to VARIANT ?
The data is getting lost if i use ColeVariant.

If you paste your code here, that would be more helpful but simply u can do it by setting the vt of variant to VT_BSTR and then create a bstr. Put the string in BSTR by using ::SysAllocString and set that BSTR in the variant.
Something like:
BSTR bstrString = ::SysAllocString(str);
VARIANT var;
var.vt = VT_BSTR;
var.bstrval = bstrString;

I have sumthng like this
VARIANT getData()
{
unsigned char* puc_Data = " SOME TEXT ";
// I am converting the above unsigned char to whar_t* using
MultiByteToWideChar(CP_UTF8,..,puc_Data,len,wchar_t*,len);
// I want to take this wchar string and convert it to VARIANT
// Doing it thru COleVariant
ColeVariant var(wchar string );
// Data is getting lost sumwhere here ...
return var;
Can anyone suggest wat i m doing wrong??

Why not just do this and let COleVariant do what it is designed to do?
ColeVariant getData()
{
char* puc_Data = " SOME TEXT ";
ColeVariant var(puc_Data);
return var;
}

Ring0 is in kernel memory area. So, you must create your program
as part of kernel.
(I never create this such program, but as long as i know you must
create modularized program which is registered in OS).

Hi,
I am new to this forum>plz let me know which forum is suitable for 'C' language.
And my question is -
What are the possible ways of writing C codes using 'const' keyword. I have written some.I need few more.
Plz go thru and send me any other cases where we can use const keyword in C only not C++.Hope I will get reply as early possible.
const int degrees = 360;
int const degrees1 = 180;
const float pi = 3.14;
const char quit = 'q';
int * const var1;
const int * var2;
int const * var3
const char * const Var4;
char const * const Var5;
void test1() const;
const int * test2(); /* function returns a adress that
could not be modified */
void test3(const int *i);
const int arr1[]={1,2,3,4,5,6,7};
char const *arr="coderzone";
typedef struct member
{
char name[20];
long phno;
};
const struct member M1 = {"Marino" , 62627000};
struct member * const M2 = {"John" , 2786900};
const struct member * const M3 = {"Smith",57361777};
union single
{
int I1;
char C1;
};
const union single S1 = {97};
union single * const S2 = {'A'};
const union single * const S3 = {'0'};
Thank U..

There is nothing better than a paper and ink bounded book to learn C or in that case any programming language. To start with C please use the The C Programming Language by Schaum Series and move onto The C Programming Language by Dennis Richie and Brian W Kerningham, Pearson Education Publication.
But if you still insist on online Sites, best would be to Google the keyword and choose the best site upto your understanding.

what is the final goal behind this question please ?
const only means that the variable/object to which it is declared cannot be modified once initialized.

Ya, You can draw in any area of you application using device context. You can also restrict the area of drawing.
Have a look over:
CPaintDC, CClientDC, CMetaFileDC and CDC.
Well, everything depends on where and in which kind of application you want to draw. Try to be specific what exactly you want.

Clean the build and rebuild it. sbr file is a source browser file needed to have the enlisting of the constituents of the build.
