Issue with program to automate excel

[Haroonrulz]

Dear C++ Gurus/Experts,

I am writing a program to automate excel.My program is working well when I use integer (Write/Read) in excel.My program also works well when I use string.But the issue appears when I use array of strings.I am getting the issue as below
"error C2664: 'SysAllocString' : cannot convert parameter 1 from 'char *' to 'const OLECHAR *' ". Please Help.

Program:

//working good with strings

for(int i=1; i<=15; i++) {
for(int j=1; j<=15; j++) {
// Create entry value for (i,j)
BSTR b;
VARIANT parm1;
b = SysAllocString(L"Haroon"); // this line working good
parm1.vt = VT_BSTR;
parm1.bstrVal = b;
// Add to safearray...
long indices[] = {i,j};
SafeArrayPutElement(arr.parray, indices, &parm1);
}
}

//Having problems with Array of strings (Same as above but with array of string)

//Array of strings

char *hrs[]={"noor","riz","vignesh"};

for(int i=1; i<=15; i++) {
for(int j=1; j<=15; j++) {
// Create entry value for (i,j)
BSTR b;
VARIANT parm1;
b = SysAllocString(hrs[0]); // issue in this line
parm1.vt = VT_BSTR;
parm1.bstrVal = b;
// Add to safearray...
long indices[] = {i,j};
SafeArrayPutElement(arr.parray, indices, &parm1);
}
}

I believe an OLECHAR is a wide char. You could try:

const OLECHAR* hrs[] = { L"noor", L"riz", L"vignesh" };
