Bitmap arrays

Hi all!

I've been using VB6 for a few years now and I've finally decided to move to .NET a few weeks ago.

I've now got a small problem, I'll explain it the best I can...


I want an array of the bitmap variable with the resolution declared.

For example: -

Dim bmpPicture(10) As New Bitmap(320,240)


Problem 1: It won't allow the "new" keyword and if I take it out the resolution can't be declared.

Problem 2: If I just do: -


Dim bmpPicture(10) as Bitmap

bmpPicture(0).SetResolution(320,240)

OR

bmpPicture(0).SetPixel(320,240,Color.Black)


...I get a run-time error, something about a null exception or reference on those lines.

I can use the bitmap variable OK but I can't get it to work as an array - Which is what I want!!! :mad:


What is going on? :rolleyes: I'm confused! VB.NET so far seems to be a different lauguage!!!

I hope someone can help me since I'm new to VB.NET and I've been trying to get it working for a week now!


Thanks in advance.

To make the bitmap you have to load it from something else instead of out right. For instance from a file like this:

VB Code:

Dim bmp As Bitmap = Bitmap.FromFile("..mybmp.bmp")

No, that isn't true, the image object can't be created directly, but the bitmap can (I do it all the time). Here is what the docs say about the image class:

Quote:

---

An abstract base class that provides functionality for Bitmap, Icon and Metafile descended classes.

---

Now, to figure out how to create an array of bitmap objects, you do this (this is also how the MSDN library suggests to do it):

VB Code:

Dim bmpPicture(10) As Bitmap
Dim iCounter As Integer
 
For iCounter = 0 to 10
    bmpPicture(iCounter) = New Bitmap(320,240)
Next
 
'Now do what you want with them.

hellswraith: Thanks alot! That code did the trick! I searched the MSDN but found nothing! Where excatly did you find it?

Thanks for your quick response.

I can't remember now, but I was searching with the words 'arrays' and 'objects'.

Glad to hear it works.
