View 1 RepliesI have a fileupload control in my form which stores image to the SQL database as binary data.
BUT it stores as 0X000000.... I just realized that.
BUT IT DOESN'T MAKE ANY SENSE BECAUSE WHEN I PRINT THIS BYTE ARRAY IT SHOWS THE CONTENT.
This part is the server side code:
[Code]....
StoreToDatabase function:
[Code]....
DisplayFileContent function:
[Code]....
Displaying function shows like 2552162552240167470737001110960960025521906708667658777998101220131211111225181............BUT IN DATABASE it stores like 0X00000000000000000...

View 1 RepliesI have uploaded a .jpg image and resized as Small and Large thumbnail. The small image is (135 X 173) but after resizing the small thumbnail image file size is of 40.8 KB. And mostly all images (around 64) thumbnails having file size more than 40 KB. Due to which thumbnails taking lot of time to get display.
Is there a way through which we can reduce the image file size upto 8 to 12 kb, but without effecting image quaity??
Below is the source code that i am using for resizing an image:
If FileUpload1.HasFile Then
Dim stream As Stream = FileUpload1.PostedFile.InputStream
Dim x As String = IO.Path.GetExtension(FileUpload1.FileName).ToLower
If x = ".jpg" Or x = ".jpeg" Then
Dim image As New Bitmap(stream)

View 3 RepliesI would like to be able to read an image based on a url hosted elsewhere. To be clear, this is a legitimate service that is provided and they do allow caching of data, so I'm not trying to steal someone elses data.
So far I have the following code:
public static byte[] GetBytesFromUrl(string url)
{
byte[] bytes;
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);
WebResponse resp = req.GetResponse();
The area that I'm looking to improve on is the emboldened line. I think it would be better to read in say 1024k chunks until the file end. Can anyone help me out with the syntax for this?

I tried doing a search about saving a gridview as an image but have not found anything that works. I need to capture it or create one as an image to send to a mobile device for a dashboard. I know people tried capturing the grid like a screen shot but is there any other way? Sometimes the grid goes off screen. I assume i could create an image dynamically right? The tough part is setting the width of the columns and right/left justifying the data. Even if I could save an html table to an image also that would work.
View 1 RepliesI'm using varbinarymax.....IN SQL gridview image and setting the nullimage value doesn't this problem.. I'm looking for code that can make this lil miracle happen
& it doesn't really matter which way , whether the code says if image null then display this image from ~/Images/thispic.jpg or if i1 display this image from ~/Images/thispic.jpg for a little bit more insight into this I'm creating a legend for the database and the null has been used for displaying one pic so i'm after the 1 or visa versa to display another image.... and i'm not trying to upload pics to 1000 plus documents, and when i came at it from a sql angle tying 5 tables together the parent table ended up not sending the proper return. is this even possible or am i ahead of visual studio
i have an image file which is of (600* 800 size) or any size . now i need to convert them into an thubnail image size which is of size **(110*110)**
but if i reduce the size of an image i should not change the Quality of image. as once we reduce an image size the the Quality of the image is gone
is there any way without affecting the Quality of the image we can convert them into an thumbnail image[ is there any built in class for that in .net)
