Gee, it sure would help if you told us what the error was.
Is IIS pointing to the right directory ? Does the target machine have the .net framework installed ? Was it installed after IIS ( so that IIS knows about ASP.NET ) ?

AND..
also when i open the Microsoft Visual Stdio.NET..n see the Debug--->Process.. i dont find the aspnet_wp.exe there.. is there any prob in the .NET Framework >??

I've had this in the past, and I found an article on MSDN that showed me how to fix it. I recommend googling your error message in quotes, you're bound to find the solution that way.

I'm trying to bind a picture box to my access 2003 Db in vb.net
Here is my code
Dim b As Binding = New Binding("Image", dsComics, "comiclist.ComicCover")<br />
AddHandler b.Format, AddressOf ConvertPicture<br />
Me.picCover.DataBindings.Add(b)<br />
<br />
<br />
<br />
Public Sub ConvertPicture(ByVal Sender As Object, ByVal e As ConvertEventArgs)<br />
Dim b() As Byte = e.Value<br />
Dim ms As MemoryStream = New MemoryStream<br />
ms.Write(b, 0, b.Length)<br />
Dim bmp As Bitmap = New Bitmap(ms)<br />
ms.Close()<br />
e.Value = bmp<br />
<br />
<br />
End Sub
The line in bold is where it bombs, any ideas

'use to save image file
Dim arr() As Byte
FileOpen(1,"FilePath" , OpenMode.Binary, OpenAccess.Read, OpenShare.Shared)
'Resize array so that it can accomodate the file
ReDim arr(FileLen("FilePath") - 1)
FileGet(1, arr)
FileClose(1)
'use to read image file
arr = ds.Tables("TableName").Rows(0).Item("ColumnName")
'comapny logo is the name of PictureBox control
CompanyLogo.Image = CompanyLogo.Image.FromStream(New IO.MemoryStream(arr))

I tried that and it bombed here:
picCover.Image = picCover.Image.FromStream(New IO.MemoryStream(arr))
might it be a problem with access?
|
|
|
|

use Dataset to retrieve and save image
I am using following lines .there is no error
arr = ds.Tables("CompanyInfo").Rows(0).Item("CompanyLogo")
CompanyLogo.Image = CompanyLogo.Image.FromStream(New IO.MemoryStream(arr))
there is also an article with demo project(using access) is available in this group. try to search with keyword "Image"

i m trying to stream media files on VB.NET interface using Windows Media Player component.. but its not being played..
well, i hav tried embedding the windows media player component on the WebApplication.....it is appearing on the client side but it is not able to play any files...... and we are not able to even select any controls provided in the player...
we are using Windows 2000 Advanced Server as OS.
actually we dont ve much idea about how streaming takes place on the internet and do we need to add any other codec or component to achieve Media Streaming ???
waiting for replies.
thanks..

If this is your "VB Client" app for you "media server", why are you using a web app? You never said anything about that before... All you need to do is include a link to the video file on the server, in URL form. The client side will take care of the rest when the user clicks on the link.
And yes, I gave you a 1 on this question. I don't live here at CP. I have a life and like to spend alot of time with her. So that means I can, and WILL, disappear from CP whenever I want, leaving your questions unanswered if you direct them at me.

I am new to vb.net and need some help, I am trying to write a program for multiplication. I need to use the next method from an object of type random to produce two positive one-digit integers, that should display a question like "How much is 6 times 7?" and type the answer in a textbox.
I want to check the answer and display a message in a label of either "correct" then ask another math question, or "Try again" in the same label and try the same math question again.
I would appreciate any help with this, I know this may not seem like a very tough task, but being new to this makes it difficult for me.
thanks, John

Despite the fact that someone has done your homework for you, you should really look over the code, work out how it works, and in future, try to do your own work and post specific questions when you get stuck.
