Hello, I'm using a multipart/form-data upload to put an image into SQL
Server, and it appears to be working (though the Image field in my
table still says "binary"). The upload code is:
Dim intImageSize As Int64
Dim strImageType As String
Dim ImageStream As Stream
intImageSize = Picture.PostedF ile.ContentLeng th
strImageType = Picture.PostedF ile.ContentType
ImageStream = Picture.PostedF ile.InputStream
Dim ImageContent(in tImageSize) As Byte
Dim intStatus As Integer
intStatus = ImageStream.Rea d(ImageContent, 0, intImageSize)
'make connection, write SPs, open connection, etc.
Try
dbComm.ExecuteN onQuery()
Connect.close
Catch SQLexc As SqlException
Response.Write( "Insert Failed. Error Details are: " &
SQLexc.ToString ())
End Try
--------------
I'm pretty sure that's working fine, but I can't see the image when I
use this code:
'make connection, then SELECT Image, Imagetype FROM Pets WHERE
[User]=@user AND Petn=@petn
'stored procedures
Dim Reader As SqlDataReader
Reader = dbComm.ExecuteR eader(CommandBe havior.CloseCon nection)
If Reader.read=Tru e Then
Response.Conten tType = Reader(1)
Response.Binary Write(Reader(0) )
Else
End If
Reader.close
Connect.close
----------------------------
All I'm getting is a blank page! Any ideas why this isn't working?
Thanks. 0 936 This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics |

Hi everyone,
I am successful in retrieving the image from the table (.TIF), however, the
retrieved file does not work. It looks like an image file - extension, size
and all, but the image is not visible. Any ideas? I'm including the first
few lines (image opened with Notepad) of the file below.
Please, help.

Hello All,
I have some pictureboxes on a VB.NET form that are linked to an AccessDB. If
the user wishes to open or edit an image, I need to save the image in the

the default for the users system. I tried to do
picturebox1.image.save(filename), which results in "A Generic error occured

Can some help me out retrieving word, pdf, etc. docs and streaming to the

I'm saving the docs as an image data type along with it's original filename
and retrieving them using a datareader but I'm not sure how to set the
headers properly (i.e Content-Length)
Articles on this using C# would be a big help. Thanks.

I am retrieving images that I stored in SQL Server on my web pages in C#. I
have no problem with the images displaying, however, I am trying to wrap the
image with an <A HREF ..." and each time I try, it acts like the link is not

What is the proper way to do this?
Thanks.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
