VB.Net pictureboxes and loops.?

Question

I'm a newbi programmer (halfway through my 1st year of computing at AS)

i want to have a for loop the set the image inside a picture box to a set image from my hard-drive.

I don't want to have to do 42 of these

PictureBox43.Image = System.Drawing.Image.FromFile("")

Changing the number everytime. But when i use a for loop

For i = 1 to 42
Pictureboxi.image = System.Drawing.Image.FromFile("")
next

I know it's because the pictureboxi is considered a name for a picture box and the computer can't find my pictureboxi.

So what way is there for me to make this loop?

I'm using VB.net on visual studio 2010 on the college computers by the way.

Answer 1

If you look at the link below it sounds like it gives an answer to your question, however it is probably best to refactor your code as the author has done to use an array of pictureboxes. Hope this helps.

Answer 2

You could add them all to an array like this:



dim pictureBoxes(42) as PictureBox = {PictureBox1, PictureBox2, ...}



Or use reflection and get the fields:



for i as integer = 0 to 42



dim name as String = String.format("PictureBox{0}", i)

dim info as FieldInfo = Me.GetType().GetField(name)

dim pictureBox as PictureBox = DirectCast(info.GetValue(me), PictureBox)

dim file as String = String.format("FileName{0}", i)

pictureBox.Image = Image.FromFile(file)



next i

Answer 3

dim myPictureBoxControl(41) as picturebox



for i=0 to 41



'INITIALISE CONTROL

myPictureBoxControl(i) = new picturebox



'SET PROPERTIES OF CONTROL

myPictureBoxControl(i),Name =

myPictureBoxControl(i). image = image.fromFile( )

myPictureBoxControl(i).location = new system.drawing.point( xposition , ypostion )



next



:) Something along those lines is what you need
