I have a friend that is working at a local college who called recently because he was having some trouble with his CSS using the Module Settings feature where you can add additional code for the Module’s header and footer.

If you aren’t already aware of this feature, now would be a good time to learn about it.  it can be used to embed javascript into your form, add or change CSS or even provide additional wrapper code for your module.

This is part two of the discussion I started yesterday about the StackOverflowException, where I explained how memory gets allocated for the different types of variables we have in our systems and how understanding that can prevent the StackOverflowException.  The question came back with some code this time which looked something like this:

private mystruct[] m_struct = 
    new mystruct[6000000];
private mystruct[] GetStructArray()
{
    m_struct[0] = 
        new mystruct(3, 2);
    ...
    m_struct[5900000] = 
        new mystruct(5,4);
}
struct mystruct
{
    public mystruct(int i,int j)
    {
        m_i = i;
        m_j = j;
    }
    public int m_i;
    public int m_j;
}

This post has been percolating in my brain for several weeks now and I think it’s finally at the point where it’s “done.”  Well, see…

The problem area is this.  At what point and under what conditions would you write the code yourself vs. using a content management system?  And if you were to use a content management system, which one should you use and why?

Along the way I’ll tell you what my current choices are, but more importantly, I’ll tell you what my thought process is.  So even if you decide to use different tools than I do, you can ask the same questions to select the tools you have decided to use.

In the last several posts, I’ve demonstrated various ways of getting data onto the screen.  What I’ve purposely omitted up until this point is how to update this information.

So let’s start by going back to the demo we created in Febuary.

What we ended up with is an application that would display the First name and the last name out of the Person class.

What we want to do today is to update the code so that the person class gets its data from a database on the server using a web service.  So the first thing we’ll want to do is create a web service.
