(Newbie problem) Setting array values?

[meretrix]

test = new Byte[1600];
for (int i=0; i<40; i++)
for (int j=0; j<40; j++)
test->SetValue(0x0A, (j*40)+i);

gives the error: "void System::Array::SetValue(System::Object __gc*, int): cannot convert parameter 1 from 'int' into 'System::Object __gc*' "

How do you set the values of an array?

Is this in managed C++?

 

[meretrix]

Yes it is.

test= 2;

Now it spits a new error at me...

'[' : Cannot perform pointer arithmetic on __gc pointer 'System::Array __gc*'

(That's what I tried to begin with, by the way... I've done plenty of C programming, but this managed C++ stuff is totally new to me.)

You need to box the object into a managed object.

test->SetValue(__box(0x0A), (j*40)+i);

You may need to do it more like this.

int val = 0x0A;

test->SetValue(__box(val), (j*40)+i);

Since I'm not sure if __box will work on straight values rather than variables or objects.

Perfect! I had to do "unsigned char val=0x0A" instead of "int," but it works now. Thanks a lot!
