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.
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..

View 1 RepliesI am trying to save some resized images to the server. Why I get the following error on the vSmlImgFle.Save(vTmpDir.ToString & vFile.Name, ImageFormat.Jpeg) (in red below) line?
A generic error occurred in GDI+.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.Runtime.InteropServices.ExternalException: A generic error occurred in GDI+.
And while we are on the subject of dealing with image files, is there a way to get the file format from the original file, rather than looking at the file extension to determine the file type:
If Ext = "JPG" then
Type = ImageFormat.Jpeg
Else if Ext = "JPG" then
Etc.
I thought that vImgFormat = vOrgImgFle.RawFormat might do it but that seems to return something completely different than ImageFormat.Jpeg.
Code:
Protected Function CopyScaleImages(ByVal FileSet As FileInfo())
Dim vTmpDir As New DirectoryInfo(Server.MapPath("~/SanInspPhotosTemp/"))
Dim vDir As New DirectoryInfo(Server.MapPath("~/SanInspPhotos/"))
Dim imgHght As Integer
[Code] .....
I m facing one problem which is related to Bitmap Image Actually My image is saved properly without iis server but when i run application on iis server then its give Exception "A generic error occurred in GDI+."
I m using this code-
Byte[] bytes = (Byte[])ds.Tables[0].Rows[r][1];
MemoryStream memStream = new MemoryStream();
memStream.Write(bytes, 0, bytes.Length);
System.Drawing.Bitmap origBMP = new System.Drawing.Bitmap(memStream);
System.Drawing.Bitmap newBMP = new System.Drawing.Bitmap(origBMP, 100, 150);
System.Drawing.Graphics objGra = System.Drawing.Graphics.FromImage(newBMP);
objGra.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.AntiAlias;
objGra.InterpolationMode = System.Drawing.Drawing2D.InterpolationMode.HighQualityBicubic;
origBMP.Dispose();
newBMP.Save(Server.MapPath("ImageUpload\" + r + ".Jpeg"), System.Drawing.Imaging.ImageFormat.Jpeg); //exception throw "A generic error occurred in GDI+."
newBMP.Dispose();
objGra.Dispose();
i need to save multiple documents stored in SQL server as Image type to disk.
What i want to do is "backup" all files in a table (column) to disk, zip them and Response.TransmitFile(FilePath) to client.
I could use C# ot VB but that would require a lot of connections to database or a lot of server memory and i don't want that, becauze there are a lot of files to be saved Since SQL can write files to disk i was thinking about saving those files to disk directly from sql. Something like when u're doing a backup

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?
