I 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?

I use to store client Images in DB in bytes, the problem is how can I render that image on .aspx page
View 2 Repliesi have an image field in my sql server table , i want to dislay it ( databound) in a grid view.
how can i do it ?
I have a database, one field is named "clicked" with values 0 or 1.
When the gridview is displayed I would like to show the value from the field "clicked" to be displayed as an image (example: instead of 0 to display and for 1 to display)
Is it possible?
Just wondering if anyone has ever managed to find a way to have a datagridview image button column in a template field which display different images on different rows depending on some data element in the row. Our application needs to display a series of fees charged against an account column which will be either less then 500, 500 to 1000 or >1000. Some of those fees are charged at a full rate, others at a partial rate, and some are not charged at all. The user would like to see a simple 3-state graphic which would convey the simple info: full-charge, partial-charge, or no-charge. Sounds easy enough but I've not yet managed to find a way to do this. Every time I attempt to modify the individual cell's graphic it seems to want to change the graphic for all the rows.

I have a page which displays details and a pictures of employees. The details are stored in a SQL database and the images are on the server. How can I set a default Image to display (e.g. an Image saying "Awaiting Image") if an employee picture is missing?
I can't use NullImageUrl as the Images are not stored in the database. I can't use the solution found on [URL] as an ImageField does not accept an ID attribute.

I created a image handler...
Partial
Class
ImageTemp
Inherits System.Web.UI.Page
Protected
[Code]....
1.Should I be able to just open the Image handler and see the image...if so then I think my problem is in it because all I see is a blank screen.
2. Is image/png a legitimate image type? The file is a .png file but I have found no information that this is a image type.
3. Not sure I have the IMAGEURL coded correctly.
I have hardcoded my variables in the image handler just to test.
I want to achive on functionallity like below.
I want to Dispaly image after image selection.so Users can see image at that moment.
I have a fileupload control in a contentplaceholder in a masterpage. I have to preview the image whenever I browse an image beside it in an imagecontrol.
My application is running on a different server .So I can't give the filepath of my local system.
Also I don't want to store the image in any location and i'm not supposed to use any session variable to pass it to generic handler.
I 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?

View 1 RepliesI have a service which reads an image stored in the database. I want to be able to read an image stored on the file system and return that back to the requestor.
View 4 Repliesthis is my aspx page code :
<a runat="server" id="hlkmail"><img src="../images/send_mail_icon.jpg" alt="" /></a>
<a runat="server" id="hlkgallery"><img src="../images/galleryl_icon.jpg" alt="" /></a>
this is code behind (aspx.vb) :
hlkmail.HRef = "sndmail.aspx?Clientname=" & clientName
hlkgallery.HRef = "pgallery.aspx?Clientname=" & clientName
above code shows fixed images.
i want to display image dynamiccally depending upon the db value.
i have a stored proc that returns hasmail ='true/false' and hasgallery='true/false' from database.
if true i want to display send_mail_icon.jpg else send_mail_icon_watermark.jpg
and gallery_icon else gallery_icon_watermark.jpg. i want to do this in code behind using if loop.
