but in "picturebox(i) i got error

its mean that i cant use index for picturebox?

so what i have to do?

if there is another way please post it

thank

A picturebox doesn't have an index it is merely for displaying images. If you have loaded your pictures into an imagelist then you can set the image for the picture box from your imagelist....

me.picturebox.image = me.imagelist.images.item(the index of the image you want to show)

Is this what you are trying to accomplish?

Add all the PictureBoxes to a Panel and use it's Controls collection

For i As Integer = 0 To 299
  DirectCast(Panel1.Controls(i), PictureBox).Image = ImageList1.Images(i)
Next

Are you really sure that you want to have 300 PictureBoxes? I guess there could be reasons for it but it sounds unusual. Perhaps you could tell us what you're trying to achieve.

I totally agree with your question, jmcilhinney. 300 pictureboxes does sound like just another "I'm in love with VB6, don't VB.Net got control arrays?"...

thnaks it works fine

but why the image when load from listimage have bad quality?

the colordepht also set to 32 bit

but the quality is not best

thanks

If you changed colordepth after you added the images to imagelist, then they will be the imagelist default value 8bit .Net 1.1 (4bit .Net 1.0).

Set the depth to 32bit then add images.

::edit:: I tested 'another' and depth change was applied either way.. the first I had to remove images, change depth, then re-add. strange, but it's something you can test.
