I don't think this is the right way to define an array of 10 integers:

C++

users_NoVhInfo[i] = {1,2,3,4,.....};

Have a look at array declaration and initialization here:http://msdn.microsoft.com/en-us/library/aa288453(VS.71).aspx[^]

Rectify your code and then post your experience.

Assuming the code snippet provided is some mangled psuedo code. Check your for loop is actually doing something along the lines of:

C#

int[] users_NoVhInfo= new int[10];
for(int i=0;i<10;i++)
{
    users_NoVhInfo[i]=i;
}

And you're then calling a function passing in the array, then you shouldn't see that error (due to the array). I would follow what's happening to that array very carefully using the VS debugger.
