Re: The API

There's no API calls needed. If you have a picturebox control and an image file, you just do the following:

VB.NET Syntax (Toggle Plain Text)
PictureBox1.Image = Image.FromFile("C:\somepic.jpg")
PictureBox1.Image = Image.FromFile("C:\somepic.jpg")

Of cource, there are other ways to get and display images depending on the source of the image.

Re: The API

Still no API needed.

VB.NET Syntax (Toggle Plain Text)
Imports System.IO
 
Dim MemStream As MemoryStream
Dim ByteArr() As Byte
 
' Read image bytes from the file
ByteArr = My.Computer.FileSystem.ReadAllBytes("C:\somepic.jpg")
' Create a memory stream from the bytes
MemStream = New MemoryStream(ByteArr)
 
' Create an image from the stream
PictureBox1.Image = Image.FromStream(MemStream)
Imports System.IO

Dim MemStream As MemoryStream
Dim ByteArr() As Byte

' Read image bytes from the file
ByteArr = My.Computer.FileSystem.ReadAllBytes("C:\somepic.jpg")
' Create a memory stream from the bytes
MemStream = New MemoryStream(ByteArr)

' Create an image from the stream
PictureBox1.Image = Image.FromStream(MemStream)

and the picture box is a control in the repeater control.
