Web Forms :: How To Display Image Preview Without Saving In Database Or Folder
Apr 28, 2013
i used a file upload control to upload file..after uploading i want to preview image without storing its path or storing in DB or solution explorrer folder.when i upload using fileupload control..path of image comes in fileupload control now i used a button so,that on button click image should be displayed in image control..
I've been tasked with creating a page where the user can do the following in this order:
1. browse to and select a jpg image 2. preview the image that the user just selected 3. if the user is happy with the preview then click the GO button to load the image to the Image folder.Does anyone have any good examples or sample code of how to do this?
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 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)

I 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:

Displaying function shows like 2552162552240167470737001110960960025521906708667658777998101220131211111225181............BUT IN DATABASE it stores like 0X00000000000000000...
