simple dot rendering width directX 9

P: n/a
First I want to say I'm very new to directx.

I'm trying to build a simple game. I already have a loop and sort of
GameTimer. With this I was able to render a "color-fading"
background.

But offcourse I want more ;-).

I'm trying to render a group of dots.

this is my dot-array:

public CustomVertex.TransformedColored[]
DotData;

And I'm trying to fill it this way:
[code:1:cc81f228a9]
for(int i = 0; i < 100; i++)
{
DotData[0].X = rand.Next(100);
DotData[i].Y = rand.Next(100);
DotData[i].Z = 1.0f;
DotData[i].Rhw = 1.0f;
DotData[i].Color = Color.FromArgb(rand.Next(200) +
55, rand.Next(200) + 55, rand.Next(200) +
55).ToArgb();
}[/code:1:cc81f228a9]

Compiling goes well, but when i launch the application I get this
error (translated from dutch to english):

The appication generated an exeption wich cannot be processed.

[code:1:cc81f228a9]Process-id=0xb48 (2888), thread-id=0xf04
(3844)

Click OK to close the application.
Click CANCEL to track errors in the application.[/code:1:cc81f228a9]

When I click cancel it says the error-tracker isn't available.
And when I click OK the application exits.

This code produces the same error:

[code:1:cc81f228a9]DotData[0].X = 10;[/code:1:cc81f228a9]

And when I comment that line all works well (no dots offcourse, but I
do see the fading BG).

Does anyone know what is wrong?

Thanks in advance,
Jules
