Just when I get my program back and running. I code in the matrix manipulation part of it and I get this stupid error. Here is the line and the error...

  
ColorMatrix = new (unsigned char[hColorMap.sizex][hColorMap.sizey]);

error C2540: nonconstant expression as array bound

Anyone bumped into this before? I make a stupid error? I looked over K&R, can''t figure it out.

As far as I understand, you can''t allocate multi-dimensional arrays. You have to have the first one be a static array size, and then you can allocate the second.

I think this should do it for you:

  
unsigned char **ColorMatrix;

//...


ColorMatrix = new unsigned char *[hColorMap.sizex];
for(DWORD i = 0; i < hColorMap.sizex; i++)
    ColorMatrix<i> = new unsigned char[hColorMap.sizey];

//And to delete:

for(DWORD i = 0; i < hColorMap.sizey; i++)
    delete [] ColorMatrix[i];

delete [] ColorMatrix;

I havn''t tested that, but I think it should work
