in my project i am allowing user to select multiple images at a time and i am passing the ids of these images to next page WATERMARK...
in the WATERMARK page i am allowing users to select combos like for a particular image id they are able to select different messages to embed...
but it performs watermark on only one image id which is selected at the end....
here is a piece of my code..
[Code]....
In my project i have a table named WATERMARKED_IMAGES where i have columns like WID,IMAGE_ID,LOGO_ID,POS,ALPHA,SECRET_KEY[IMAGE_ID and LOGO_ID here are the foreign keys]....i need to retreive IMAGE_CONTENT from another table IMAGE using IMAGE_ID ..the same way LOGO_ID also...after retreiveing i need to embed the logo in the image at the pos and with alpha value mentioned in the table WATERMARKED_IMAGES...
but the problem here is that as i am able to retrieve data IMAGE_CONTENT,LOGO,CONTENT,POS,ALPHA in a single query] from database but i dont know that how to use this detail and where to use these details in my WATERMARK class...
How can i do that with ASP?
Is this process going to be a great overload for the server?
Could i use an image for a watermark instead of simple text?
I am doing a project on digital watermarking. This is the process. The user will choose his image file to upload, chooses his image key(either from the visual studio gallery-folder name is Image Key, or he chooses his own from the directory).
He enters a password, and this password will be embedded into the image uploaded.
Next, there is an option to digitally watermark the image (This is where I am having problems - stuck with the codes)
Here is the work so far, and I couldn't get any further.

View 1 RepliesIs there a way to upload image and save to folder with watermark of Copyright on image ?
View 1 RepliesIs there a way to process images once uploaded to my asp.net site, to put a watermark or some text across the image to copyright the images? I would like to do this server-side if possible.The other option I have discovered here [URL] would be to store the images as they are on the server, but to manipulate the display so it appears the image is watermarked . However, this solution is in PHP. Does anyone know a good PHP to VB.NET translator?! Or does anyone have a good suggested link, idea or code? Or can I add PHP to my ASP.NET site?
View 4 RepliesI have a page in which there are multiple updatepanels and each of these update panels are trigerred by different triggers.
These update panels are used to do Async post back and the page is updated with the data retrieved from the async post back.
Now the issue i am facing is that since there are multiple update panels, the update done by one panel is lost when the other panels does the post back.
let me know if any one knows on how to solve this issue.
I want to know if we can use multiple membership providers simultaneously in a single ASP.net application.
View 1 RepliesWas wondering if someone can help me out with this multi update problem
I have a webform that populates a single table but due to certain dropdown data conditions it could also potentially populate 3 other tables
The tables information populates a gridview with amounts from accounts etc..
e.g.
Table 1
Site DataType account update
34 SS 12.50 N
Table 2
Site account
34 12.50
Say the above entry has the updated column changed to Y via the webform the amount 12.50 should disappear from the gridview. I was
a bit shortsighted and added the additional tables afterward. The information on the gridview pulls from the additional tables and since
the first table and the additional tables are not linked the data still stays the same in the gridview
I do have an Id column on both tables but unfortunately I added the rest of the tables after the first one so the Id's do not really match.
How can insert, Display ,update multiple records simultaneously through GridView in Asp.net.I have Button for insert, update . I want insert, update multiple records through a GridView in a single click.

Problem is when I upload image and click on btnupload it shows image in new window with watermark text but it doesn't save it into host...
I want when I click on btnupload it doesn't show image in new window I want it just uploaded image with watermark into host...
How I can do it?
In general, If multiple users thru an application try to update the same tables in database simultaneously, then by default on what basis the priority will be given.Like if we don't have any extra logic for the locking implemented.
View 3 RepliesI have a page that display like a print pre-view. It shows the watermark in the background. But when I print it, it doesn't include the watermark. I know in IE7 you can change your IE settings to make it print the water mark but in IE8 you can't do that. Is there another way to print my water mark out? Here's that part of the code:

How to Display the treeview control with multiple images(each link should be with one image) instead of + images in asp.net
View 2 Repliesi posted a problem few days ago
i was trying to upload images
after using the upload asp control
i save them into an array to upload them all at once this is working fine on the localhost but if the array contains more than 3 images on a different PC on the domain it gives me an exception
the exception "Cannot access a closed file"
i am saving my images in a folder in the same project and only the path in data base i do not know if that the best solution but i considered the performance that way will be better
i tried the solution mzmishra gave me
< httpRuntime maxRequestLength="10240" requestLengthDiskThreshold="4096"/ >
it did work and there is no more exceptions in different permition levels but in a permition level the images does not saved in the server so when i tried to view them there is no image to view.

View 1 RepliesFirst off loving the new look, well done to the moderators / owner of the site.
Okay I want to display in a div 16 image controls which are 100 x 100 px in dimension. I need to display four rows of four but I just cannot get them to line up.
i am creating a page that will display multiple images from the database. i can do it if i will only display one image, by using a page to be rendered as image. something like this...
using (SqlDataReader reader = comm.ExecuteReader())
{
Byte[] images = new Byte[]();
while (reader.Read())
{
Response.BinaryWrite(images);
}
}
and in the aspx file i have: <asp:Image ID="imgPhoto" runat="server" ImageUrl="~/ShowImages/LoadImages.aspx" Height="100px" Width="100px" BorderWidth="1px" /> what i want to achieve is to display multiple images from the database without making a page to be rendered as image...
