why transparent Image background is still shown?

[saibaba111]

Hi all,

I hope someone can help me with this.

I have made transparent gif images using photoshop hoping that when i use them in windows forms picturebox the background won't be visible . They blend with the different backgrounds but still there is a rectangular background around the picture with the same color of the picturebox background. why is this happenning?
And also when I overlap two images I want them to be see through so that the picture beneath is visible.

Thank you all
Sai

Ask each question only once please. Your other thread has been deleted.

This post is most suitable for the GDI+/Graphics catagory so it's been moved there.
You should use GDI+ to draw your images. The background of the picturebox is visible because PictureBoxes don't support transparency.
Search this category for GDI+ and it's DrawImage method, read a bit and if you have more questions feel free to ask.

Imports System.Drawing

Private Sub pctImages_Paint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles Me.Paint

Dim g as graphics = e.graphics

Dim rect As New Rectangle(6, 12, 32, 32)
g.DrawImage(My.Resources.ImageName, rect)

End Sub

that will draw an image that has been added to your projects resources hope that helps.

as for transparent images, i would go with PNGs rather than GIFs
