Hi all,
I am building a online dating site (users may be 200-300 or more). each user can only store upto 5 images. my table structure looks like below
------
if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[UserImage]') and OBJECTPROPERTY(id, N'IsUserTable') = 1)
drop table [dbo].[UserImage]
GO
CREATE TABLE [dbo].[UserImage] (
[Bits] [image] NULL ,
[Description] [nvarchar] (300) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,
[UserId] [int] NULL ,
[UserImageId] [int] NULL ,
[UploadTime] [datetime] NULL ,
[ImageSize] [int] NULL ,
[Mime] [nvarchar] (300) COLLATE SQL_Latin1_General_CP1_CI_AS NULL
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
GO
------
I just want to know will it have any performance issue when i store images in DB rather than in file and only have a reference to that filename in DB?
I dont want my user to type the URL parameter and do silly stuff such as.
i only want them to type
www.mysite.com
and if they type in URL anything other than that it should take them to
a page saying page not found or sumthing. the reason is.
when i delete image i am getting a parameter from query. like
www.mysite.com/managepictures.aspx?UserId=12&DeleteImgId=4
that means if user passes diff. parameter it will actually delete others image and they can even browse the pic by chaning UserID para.
i dont know how to achieve this
please help
many thanks in forward
Robin

In general, storing images in a database for this purpose is probably not a good idea. Your database will grow very large over time and become unmanageable (and possibly performance will degrade too).
The better way would be to store the images in the file system and store the path to those images in the database.

I am running a procedure in a thread which is created on the click of a button. However, the process does not complete correctly. Please refer to the code below:
Private Sub cmdProcess_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdProcess.Click
Try
Dim tquery As Thread
tquery = New Thread(AddressOf Me.GetData)
tquery.Start()
Catch ex As Exception
MessageBox.Show(ex.Message, "Error In cmdProcess_Click", MessageBoxButtons.OK, MessageBoxIcon.Error)
End Try
End Sub
Private Sub GetData()
Try
Dim field1, field2, op1, period1, value1 As String
Dim m1, y1, tablename As String
period1 = Trim(cmbPeriod.Text)
m1 = Mid(Trim(period1), 5, 2)
y1 = Mid(Trim(period1), 3, 2)
tablename = "SSA" & m1 & y1
field1 = Trim(cmbField1.Text)
value1 = Trim(cmbValue.Text)
op1 = Trim(cmbOP1.Text)
field2 = Trim(cmbField2.Text)
str = "select " & Trim(op1) & "(" & Trim(field2) & ") from " & Trim(tablename) & " group by " & Trim(field1) & " order by " & Trim(field1)
ipcon.Open()
DA = New OleDbDataAdapter(str, ipcon)
DS = New DataSet
DA.Fill(DS, "qrec")
ipcon.Close()
DataGrid1.SetDataBinding(DS, "qrec")
Catch ex As Exception
MessageBox.Show(ex.Message, "Error In GetData", MessageBoxButtons.OK, MessageBoxIcon.Error)
End Try
End Sub
-- This code exits with the following error message 'Controls created on one thread cannot be parented to a control on a different thread'
Please guide me how to resolve this issue.
With Best Regards,

Hello,
I have to create a custom control which consists of a label and an ASP.Net listbox. The control has to have a public property called 'Items' which allows users to add list items to the control's listbox during design time. (much like the Items property of the original vb listbox). I used ListItemsCollectionEditor to show the ListItems Editor window.
However, when the ListItems Editor window appeared and after adding some list items, the listbox did not display the newly added items at all.
A code snippet is given below:
<editorattribute(gettype(system.web.ui.design.webcontrols.listitemscollectioneditor), _
gettype(uitypeeditor))=""> _ //displays the ListItemEditor window
Public ReadOnly Property Items() As ListItemCollection
Get
Return listitems //listitems is a listItemCOllection variable
End Get
End Property
How do I enable the listbox to display the newly added list items?

Why not use Excel? It has built-in functions to do this and lots more.

Do it in Excel then reverse engineer it to code logic... that's what I'd try.

I have too user controls in my program, one of them has a list on it, and I want to reference the list from the user control panel. To be more specific, my list is printersList in user control goPanel, and I want user control goPanel to reference it. I get the the error: "Reference to a non-shared member requires an object reference." I've done a lot of research on this error, for about the past hour, but have not been able to make sense out of it, can anyone point me in the right direction? Thanks
