Hi, I'm stuck trying to figure out how to call an image from the database by certain ids. I want to get it like this: page.aspx?pictureid=#&userid=#
here's the show.aspx:Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim PictureID As Integer = Convert.ToInt32(Request.QueryString("ppID"))Dim MemberID As Integer = Convert.ToInt32(Request.QueryString("mID"))
'Connect to the database and bring back the image contents & MIME type for the specified pictureUsing myConnection As New SqlConnection(ConfigurationManager.ConnectionStrings("objConn").ConnectionString)
Const SQL As String = "SELECT [ppMIMEType], [ppImageData] FROM [tblPP] WHERE ([ppID] = @ppID) & ("[mID] = @mID)"Dim myCommand As New SqlCommand(SQL, myConnection)
myConnection.Open()Dim myReader As SqlDataReader = myCommand.ExecuteReader
If myReader.Read ThenResponse.ContentType = myReader("ppMIMEType").ToString()
Response.BinaryWrite(myReader("ppImageData"))
End If
myReader.Close()
myConnection.Close()
End Using
End Sub
here's the formview to display image with datasource:
<asp:FormView ID="PictureUI" runat="server" DataKeyNames="ppID,mID" DataSourceID="PicturesDataSource" AllowPaging="False" EmptyDataText="There are currently no pictures uploaded" HorizontalAlign="Center" CellPadding="0">
Ok, the problem is that , i have a field called "Attach" in sql of type image, when selecting it , the field is getting data of type BYTE(). which am being unable to display them on an Image on the panel.
using the following vb.net code:
'Dim sel2 As String
'Dim myCom As SqlCommand
'Dim conn As New SqlConnection
'Dim drr As SqlDataReader
'Dim image As System.Drawing.Image
'sel2 = "select * from attach where att_desc = '" & DropDownList1.SelectedItem().Text & "' and doc_code = " & w_doc_code & " and subcode = " & w_doc_subcode & " and doc_num= " & w_doc_num & " "

Hi, Can any one help me to retrieve an image data from a table. I wanted to show the images on my web page using ASP. I am trying with pub_info table of pubs database, in this table logo is a image data type colum. I opened a record set in ASP page and I am not able to retrieve the image from the record set.
I have not seen a response to this specific question so here goes. I had working code for loading an image into my smart device SQLCE db and for retrieving images. But after upgrading my application to SQLCE 2.0 I am unable to use my retrieve code. This is what was previously working,
Dim ImageBytes As Byte = rs.GetValue(rs.GetOrdinal("OLE"))
Dim ImageStream As New System.IO.MemoryStream(ImageBytes)
frmFlashcardActive.picboxBlobToPicBox.Image = New Bitmap(ImageStream)
Help!
This is what I successfully use to save the image to the database
Dim PictureInfo As New FileInfo("My DocumentsUSAFlag.bmp") 'OpenDialog.FileName
Dim PictureSize(PictureInfo.Length) As Byte
If PictureSize.GetValue(0) <= 69 Then
Dim fsPicture As New FileStream(PictureInfo.FullName, FileMode.Open)

i'm working with a project right now that needs pdf file retrieval from the database with the use of a search engine... any codes that could make that search engine to function properly? and make it work?
Hi, I have a website which is designed to search for employee information. I have the search system working which does exactly what I want to, but as an added feature I want there to be a button which, when someone clicks on it, it takes whatever the previous search was and generates a set of data in XML format which is based on the results. For example: User searches for all entries with Forename = John; Results are listed in a gridview as per expected. User then presses button with XML on it, and page pops up with just the XML output on it, i.e. whatever results are on the gridview but in a nested XML format <records> <record> <Forename>John</Forename> <Surname>Smith</Surname> <Email>j.smith@blah.com</Email> <Ext>1234</Ext> <DeptList>History</DeptList> </record></records> I have created a stored procedure which will take the parameters from the search boxes and return the above information, but I don't know if this is the best way. Here it is for those interested: CREATE PROCEDURE ps_record_SELECT_NameSurnameEmailExtDeptasXML @Forename varchar(50), @Surname varchar(50), @Email varchar(50), @Ext varchar(4), @DeptList varchar(50) AS SELECT Forename, Surname, Email, Ext, DeptList FROM dbo.record WHERE Forename LIKE COALESCE(@Forename,Forename) AND Surname LIKE COALESCE(@Surname,Surname) AND Email LIKE COALESCE(@Email,Email) AND Ext LIKE COALESCE(@Ext,Ext) AND DeptList LIKE COALESCE(@DeptList,DeptList) FOR XML AUTO, ELEMENTS If someone could be kind enough to help me out with this, I'd be really grateful. Many thanks, Tom

I need to retrieve the available tables in a database in SQL Server 2000. I found this command and although it works I can't figure out how to filter the results.
exec sp_tables
I don't want to return the whole list, just the tables starting with "OV" and "SV". Does SQL Server 2000 support a wildcard? Like can I have it search for "OV*" or do I have to use LIKE. Did google search with no helpful results. I remember in mySQL this was simply "SHOW Tables" but this command isn't supported in SQL Server 2000.

Running SQL 7, Standard version. I had a database marked 'suspect'. I copied the MDF and LDF files to another directory, then deleted the suspect database. I tried to create a new database and attach the MDF file to it. It did not work. Any other ideas? I have no other backups of the data. I am willing to pay for consulting over the phone if necessary.
I am using the 3-tiered architecture design (presentation, business laws, and data acess layers). I am stuck on how to send the image the user selects in the upload file control to the BLL and then to the DAL because the DAL does all the inserts into the database. I would like to be able to check the file type in the BLL to make sure the file being uploaded is indeed a picture. Is there a way I can send the location of the file to the BLL, check the filetype, then upload the file and have the DAL insert the image into the database? I have seen examples where people use streams to upload the file directly from their presentation layer, but I would like to keep everything seperated in the three classes if possible. I also wasn't sure what variable type the image would be in the function in the BLL that receive the image from the PL. If there are any examples or tips anyone can give me that would be appreciated.
Hi, I want to store an image hyperlink in a sql database but don't seem to be able to do it..is this do-able? I can store a hyperlink in text format, no problem, but how do I do the same with an image? I want to use images in my images folder. I can create an image field and set the required options to display images all that is pretty straight forward but trying to display the image as a hyperlink ( actually it's a mailto: link I want to use) seems not to be an option. The purpose of this is to allow users to upload an image together with their email address and when other users click on the image it fires up their email app. I do not want to have to use a text link. Thanks
I'm trying to upload an image to a database along with some other info. I have a form to get all the info from the user that I want to put in the database. Everything's getting into the database except for the actual image data. When I do a "select * from table" query on the database, the Image field reads "err", however I have an imagetype field in the db and it reads "image/jpeg". I have the following code to get the image into the database:
