View 7 RepliesI have a database which signature images. Images are saved in binary.
I want to retrieve the image and display in an image control. I am kinda new to ASP and what seemed so simple has suddenly become a real problem.
The at the botom is how I would do it on a winform. Unfortunately I have no picturebox control in .asp. So how do I get the image stream into image1.imageurl?
Is there a way to put the stream into a session variable and then point to that as a url?
for instance replacing the last line below with this and then pointo to it from image1.imageurl?

View 1 RepliesI want to add controls (or simply texts) to a ListView inside the ItemTemplate at run time.
The reason is that in my application I don't know in advance how many controls (or texts) I should insert.
For example I have to read the fields from a database table and insert in the ItemTemplate controls according to those fields:
<ItemTemplate>
<%# Eval("fieldname1")%> - <%# Eval("fieldname2")%> - <%# Eval("fieldname3")%> - .....
Afterwards I have to bind the ListView to the table content, so I need to preserve the <%# ... %> structure for the binding
if (Session["image"] != null)
{
ImageButton1.ImageUrl = "~/IMAGE/pic.jpg?" + DateTime.Now.Ticks.ToString();
}
The session key image is from another aspx page
{
string strPhoto = Request.Form["imageData"]; //Get the image from flash file
byte[] photo = Convert.FromBase64String(strPhoto);
FileStream fs = new FileStream(Server.MapPath("~/IMAGE/pic.jpg"), FileMode.OpenOrCreate,

The issue is

I am unsure on how to perform this task, what i need to do is make a gallery with tagging. I need this as it is a requirement for the project. Each user will have there own gallery and be able to upload and delete images from there gallery. I already know how to insert and select images from a database. I will then display the gallery using a data repeator with paging, I am sure i can google an article for data repeator with paging.
My challenge is, when the user wants to save a image to there gallery, he must 1st upload the image and then i must some how display the image, when the image is displayed, i will have a text box where they can add tags, this textbox will save in the tag table for that user_id, picture_id and the tag will have an id also. I am unsure on how to do this When he clicks save, i wanna insert the image into the table, and the tag. If he does not click save, then nothing should be saved. Now the 2nd part.
In the data repeator, i want a modal window to popup when they click an image, this modal will have the image and the respective tags that where saved for this image, I am unsure how to this.
i have used Ado.net entity framework...how to insert an image to a table and retrieve it an show it.

View 8 RepliesI want to read from database where I've stored a image in binary field and display a image.
while (reader.Read())
{
byte[] imgarr = (byte[])reader["file"];
Stream s = new MemoryStream(imgarr);
System.Drawing.Image image = System.Drawing.Image.FromStream(s);
Graphics g = Graphics.FromImage(image);
g.DrawImage(image, new Point(400, 10));
image.Save(Response.OutputStream, ImageFormat.Jpeg);
g.Dispose();
image.Dispose();
}
con.Close();
This piece of code doesn't work:
System.Drawing.Image image = System.Drawing.Image.FromStream(s);
I tried the code from this article. And I got the same mistake " the parameter is not valid ". Maybe I'm not aware of something, some setting in sql server or webconfig or sth else. Anyone else who has experience from fetching images from database? The parameter is not valid is the error message. db table contains data. What am I doing wrong?
