if u store those images in a folder it will very easy. but some complexity also there if somebody delete that folder.
or else u can store images in database that is difficult but more flexible and relable.
so my suggetion is to store in database directly.
use below code to store the images in database.
If fileImgUpload.PostedFile.ContentLength = 0 Then
lblmsg.Visible = True
lblmsg.Text = "Please Browse for the New Image/Photo......."
lblmsg.ForeColor = Drawing.Color.Red
Exit Sub
End If
openAccessConnection()
Dim imageSize As Int64
Dim imageType As String
Dim imageStream As Stream
' Gets the Size of the Image
imageSize = fileImgUpload.PostedFile.ContentLength
' Gets the Image Type
imageType = fileImgUpload.PostedFile.ContentType
' Reads the Image stream
imageStream = fileImgUpload.PostedFile.InputStream
Dim imageContent(imageSize) As Byte
Dim intStatus As Integer
intStatus = imageStream.Read(imageContent, 0, imageSize)
Dim cmd As New OleDbCommand("insert into tblImg(img_title,img_type,img_stream) values(@img_title,@img_type,@img_stream)", myAccessConnection)
cmd.CommandType = CommandType.Text
cmd.Parameters.Add("@img_title", OleDbType.VarChar).Value = txt_title.Text.Replace(",", """")
cmd.Parameters.Add("@img_type", OleDbType.VarChar).Value = imageType
cmd.Parameters.Add("img_stream", OleDbType.LongVarWChar).Value = Convert.ToBase64String(imageContent)
cmd.ExecuteNonQuery()
closeAccessConnection()
txt_title.Text = ""
lblmsg.Visible = True
lblmsg.ForeColor = Drawing.Color.Green
lblmsg.Text = "Photo Uploaded Successfully......"
displayImages()

I would suggest you to store images in folder and store the image path in database.

Hi,
I am looking for some menu samples that I can work through. I did try Google. If any one has some links please let me know.
What I am trying to achieve is if I have a navigation menu on the left, and a user clicks the link, then that link must be highlights and the background must be a different colour so that the user can see where he is, something similar to:
http://groups.google.com/group/rec.music.gdead/topics[^]
See Discussions top right.
Also, when a person hovers over the menu link there is a horrible javascript link in the bottom status of the browser, how do I get that away to display something more decent?
Can anybody help?
Brendan

you asked this question before...
so still...what is your question?
I assume that you better check
if (dg.EditItemIndex > -1)
dg.EditItemIndex = -1;
BindGridView();
Your problem is the edit state of the gridview, not the changing value of the dropdownlist.
In Word you can only store 2 bytes. That is why I use Writer.

i am not interested to edit the row so i check some other value in drop down and it shows the grid.So again i select the old value in dropdown.But the gridview shows the previously edited value..........
Please help

better debug you code and check the value for slectedValue of your DDL.
You might rephrase your question because it is not quit clear what you mean and what your problem is.

Sounds like you're saying when someone clicks on an item, you want to remove it from your datasource / What have you tried ? This code won't do that, obviously.

I have created a inputbox for user to login when my web page(.aspx) is loaded. This is whats happening when i run the application..
Internet explorer opens up and waits before loading the web form, only to realise that my inputbox is hidden behind, so i have to drag the dialog(internet exporer) away then i can see the input/dialog box.
How do i make it appear in front of the web page.
This is my code:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load
Dim strPasswd As String
If Not IsPostBack Then
strPasswd = InputBox("Enter the password please:")
End If
End Sub
thanks

Um... your basic problem is that you have no idea what you're doing. Buy a book on ASP.NET and try to understand what it is and what it does. It's plain that you have no clue.
Your input box shows on the server, not the client. You just can't tell that now, because they are the same thing. Using methods like InputBox sucks in general, but you sure as hell can't use it in ASP.NET.

Thank you very much. yes you rite, this my first ASP.NET project, so i'm still learning these things.

No buddy. InputBox is a feature of Windows, you cant call them on your web page.
rather make an Inputbox yourself using HTML.

Try to use asp.net server controls for this(TextBox)

is it the same method for uploading the flash file as in the case of images?
|
|
|
|

Not sure what you're talking about specifically, but any file upload is format agnostic. It always works the same for all file types. Why didn't you just try and see ?

You need to write a custom pager control to do this.

may i know what you mean custom page control
|
|
|
|

It means you need to write your own control to handle the paging of a data grid, so that it renders the way you want.
