I am trying to make a photo gallery. I want to save the uploaded image to data base ...the article below at "
Display image after upload without page refresh or postback using ASP.Net AsyncFileUpload Control" shows how to show the uploaded image.. How to save the image in SQl Database?
I do not know how to do it.. Can the code be modified..?
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:
[Code]....
Displaying function shows like 2552162552240167470737001110960960025521906708667658777998101220131211111225181............BUT IN DATABASE it stores like 0X00000000000000000...
I am asking user to upload images using file upload control..In the database i am saving the filename as varchar. My problem is how do i save it.. If file name is saved in database where is file actually saved? If i make a folder to save,it is hard code path.. So, any way to save the file uploaded by user.
View 1 RepliesAfter uploading image it appears somewhat like its upside getting down. I have getting some other suggestion for that is use ExifLib but I don't know how to get exif detail of image and fix image orientation property if it rotated automatically..!
View 1 Repliesi 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..
View 1 RepliesI was so proud because I researched saving files and figured out how to extract the file name from what might be the full path. However, this doesn't work as I had expected. I still get the exception!
Here's the function that saves the file:
protected string SaveFile(HttpPostedFile file)
{
string savePath = Server.MapPath("~/Articles/");
string fileName = Path.GetFileName(article.FileName);
savePath += DateTime.Now.ToString();
savePath += " _ ";
savePath += fileName;
article.SaveAs(savePath);
return DateTime.Now.ToString() + " _ " + fileName;
}
i am trying to save an image to database as a byte[]
The array size before i save it = 2118.
but in SQL 2008 the maximum size for an image type is 16.
so i am trying to get the image using Response.BinaryWrite(byte[]) I get an empty image.
My website provides a facility to upload images, using the ASP.NET FileUpload control. We accept both jpeg and tiff formats but I have just decided that all tiffs should be converted to jpegs at the time of upload. If possible, I want to avoid saving the original tiff to disk. I would any sample coding for achieving this conversion prior to saving (ideally in VB.NET, though I could always run C# code through a converter).

i am using fileupload asp.net controll so how i create image preview before image uploaded
View 6 RepliesI'm trying to use an asp:FileUpload Control to allow users to upload files (.doc, .gif, .xls, .jpg) to a server that is outside of our DMZ and not the Web Server. We want to have the ability to look at these files for viruses, structure, etc prior to saving them into another directory that would allow access to outside users. From what I have read about this control is that it will allow for files to be uploaded to the web server. Can this control be used to upload files to a server other than the web server? If it can be done where should I look for this type of functionality or how do I force it to go to https:servernamefolder name (Where server name is not the web server)? Would I have to read the file then write it to the other server?
View 2 Repliesi did this code to upload file and displaying it in the image:
[Code]....
the code works good. the file is uploaded under my website here in the solution explorer: now after uploading the file,the newly uploaded file is shown in the image(since there were a few more images present in the same location but they were not shown by the image) i used this url to the imageurl:
ResolveUrl("~")
which returns me this:
WebSite1
now my question is why the newly uploaded image is shown in the image? there were several other images present at the same location and even i have not used something in my code that tells to show only the newly added image from my website into the image.
Display Images from SQL Server Database using ASP.Net only display previous images only. new images are not visible
View 1 RepliesDoes anyone know how to display the uploaded image onto the webpage after the image has been uploaded via the asyncfileupload control?
I tried setting the value of an imageurl property of an image control within the OnUploadComplete event however it seems the code 1st refreshes the page, runs through the Page_Load event, then finally the OnUploadComplete, so I'm assuming since it's run last, this is why it doesn't display the imageurl.

I've got to following function which is called to change the resolution of an image. I want to do this so uploaded image with for example 300dpi will be modified to 72dpi (for web). This question is related to another question here on SO where i'm working on.
I'm creation an extension method for this to be able to use this function on more places in my application, instead of only when uploading new files. (See above mentioned question)
public static byte[] SetDpiTo72(this byte[] imageToFit, string mimeType, Size newSize)
{
using (MemoryStream memoryStream = new MemoryStream(), newMemoryStream = new MemoryStream())
{
memoryStream.Write(imageToFit, 0, imageToFit.Length);
