I'm having issues with the way I've been reading my image datatype blobs from my SQL database (code below). This code works fine when I access this page directly. The PDF will open and works just fine. However, when I try to use this page to download a file and save it to the file-system programmatically, it fails (500 server error) and I've verified that it's the same URL either way.So, my question is what is the best way to download a file from a database image datatype and save it to disk?PDF.aspx

I need to know how can I save image in SQL SERVER 2000 by VB.NET? I made a table in SQL SERVER with two fields. One is Id[nvarchar] & another pic[nvarchar]. I got two forms there in VB.NET project. In the first form I got Picture Box[PictureBox], Text Box[txt1] & two buttons[Button1 & Button2]. I got one module there in my project.
Module code :
Public con As New ADODB.Connection
Public rst As New ADODB.Recordset

I have a SQL Server database with a table that has a column that stores an image. I have another database and I would like to store the image from the SQL Server database into it. It's type is MS Access 2000 format .mdb.
The problem is I get back the content of the column and I put them in an array of bytes as follows:
Dim arrByte() As Byte = CType(dtAll.Rows(0)("DailyProgram_Image"), Byte())
It sends me back the data of the image as byte type. When I try to save this into the access DB it give me an error because of type mismatch.

View 5 RepliesI have a client/server application set up that the client sends a word file to the server and then the server converts that word file to a .TIF and sends the image back.The stuff I have now works.Say if I sent the size of the file and the actual file byte() to the server back to back, would the NetworkStream contain both back to back? This what I though would happen. So I implemented a kind of 'turn' based interaction during the duration of the conversion process.

I want to send a image to server side using HTTPService,I am using ASP.NET for server side coding.

View 9 RepliesThe images on my e-commerce website are watermarked with an aspx script, therefore when you are browsing products, if you want to save the image it saves it as aspx rather than jpg or png. The thing is I need to give urls of jpg for a website that advertises products. There are more than 10,000 products so I can't save all of them manually, so I made a page with jquery that get's the image part of the product display page. What this page returns is this:
<div id="result"><div id="loadpic" style="width: 160px;">
<img border="0" src="http://11.11.11.11/img/picsel.aspx?code=IPHONE-32GB-4">
</div></div>
And the output is only an image. How can I return this image not as an aspx page but as a jpg or png? Since there's a script for watermarking the image and making it aspx, shouldn't there be a reverse function?

View 4 RepliesIm trying to get an image from clipboard and save it to a file (.bmp)
Here is my
Private Declare Sub keybd_event Lib "user32" (ByVal bVk As Byte, ByVal bScan As Byte, ByVal dwFlags As Long, ByVal dwExtraInfo As Long)
Private Const VK_SNAPSHOT = &H2C
[Code].....
Btw (For the first code)If I press the Button the first time and i paste it manually(ctrl+v) to the paint the printscreen image is appeared.Also If i debug the code it works perfectly and it produces the .bmp file.
So im thinking its a timing issue , so I put a sleep(3000) after the keybd_event(VK_SNAPSHOT, 0, 0, 0) command and it still doesnt work.

View 2 RepliesI'm trying to save a binary file stored in a SQL database with a SaveDialog, the function RetrieveFile retrieves the specified file from the database as a Byte array, here's what I have so far:
Private Shared Function RetrieveFile(ByVal filename As String) As Byte()

Dim command As New SqlCommand("SELECT pcfFile FROM Items WHERE pcfFileName=@Filename", connection)
command.Parameters.AddWithValue("@Filename", filename)
connection.Open()

Files are saved as "SqlDbType.VarBinary" within the database.
I get: "Index was outside the bounds of the array." on:
Dim retrievedBytes As Long = reader.GetBytes(1, startIndex, buffer, 0, ChunkSize)
The MemoryStream appears to not be retrieving the data yet the SQL syntax is correct.

I know it's not the most secure way of doing things, but the end data has to be in the txt format, otherwise I'd have used MySQL.
