Sometimes we need to either generate or download an image from a 3rd party service and want to serve up the image within the UI.
Below is an example on how to convert a MemoryStream Object that was generated from an HttpWebResponse into something that is viewable on screen or can be saved into the data base
using (System.Net.HttpWebResponse response = request.GetResponse() as System.Net.HttpWebResponse)
{
stream = response.GetResponseStream();
System.IO.MemoryStream filestream = new System.IO.MemoryStream();
//we need to convert the main stream to a memory stream in order to access the binary objects
stream.CopyTo(filestream);
BinData binData = new BinData();
container baseContainer;
Image image = new Image();
//convert the memory stream into a container object which can then be converted into a binData object which can then be defined on an image object which can then be displayed to the end user
baseContainer = Binary::constructFromMemoryStream(fileStream).getContainer();
binData.setData(baseContainer);
image.setData(binData.getData());
//define the image control on a form to the image that was generated from the memory stream
FormImageControl1.image(image);
}
