The "who" who is using the image is probably you the first time you uploaded. Make sure that you are properly disposing of objects that you use when dealing with the image. One of them must still be holding on to the image file.
I've done had this problem before when using a System.Drawing.Image object in my code to deal with a file. After you are done with it you must dispose it to get it to release it's hold on the file. This is my example:
Dim x as System.Drawing.Image<br />
x= Drawing.Image.FromFile(strMyImageFilePath)<br />
x.Dispose()
Hope this helps.

hi
try this code
public void OnUpload(Object sender, EventArgs e)
{
// Create a byte[] from the input file
int len = Upload.PostedFile.ContentLength;
byte[] pic = new byte[len];
Upload.PostedFile.InputStream.Read (pic, 0, len);
// Insert the image and comment into the database
SqlConnection connection = new
SqlConnection (@"server=INDIA\INDIA;database=iSense;uid=sa;pwd=india");
try
{
connection.Open ();
SqlCommand cmd = new SqlCommand ("insert into Image "
+ "(Picture, Comment) values (@pic, @text)", connection);
cmd.Parameters.Add ("@pic", pic);
cmd.Parameters.Add ("@text", Comment.Text);
cmd.ExecuteNonQuery ();
}
finally
{
connection.Close ();
}
}
and try

Hello,
I am working on a project and the client wants to change the font color to white and the bar itself to navy. Everything works fine, but the caret that goes along with any menuitem that has a submenu is still black. So here is the basic questions. I am using VS 2005, so .NET 2.0 is what the site is running.
Can the caret color be changed? If it is an image file, can the image be changed? Or if all else fails, can it be removed totally?
Thanks,
Leo

Hi there,
This is the image stored in the web resource, however you can replace or remove it with a couple of properties of the Menu/MenuItem classes.
MenuItem.PopOutImageUrl Property [^]

Thanks, this helps a lot. I don't know how I managed to miss that attribute, but I did.

Hello,
I have been looking around for a way to pass a custom object I created to hold a user's information across different pages. I'm trying using Server.Transfer(), but even though it gives me access to the sender's controls (like textboxes and the such), it doesn't allowe me to access the custom object I created.
So far I'm thinking in serializing the object to an XML string, so some bogus encrypting to the string and pass it as either a hidden input field or as part of the querystring.
Yet, I know there must be a better, more optimum way to do it. Can someone point me in the "right" direction?
Thanks in advance!

You should be able to put it in
HttpContext.Current.Items
or at the very least share it through the session.

If the object contains simple types, add the serializable attribute to the class and use a session to pass it throughout the session.
|

Thanks for the quick replies!
Let's see if I understand this option correctly:
I added the serializable attribute and then used the LosFormatter to give me a long, Base64 encoded string. By using s session, you mean to save this long string on a sole session variable? Is this - performance wise - better than sending the same string through a hidden input?
|
|
|
|
|
If the class uses simple types, there is no reason for anything more than the serializable attribute.
If the object (in your case, User Info) is going to be used across many pages, session would be a better option.

Hi,
One of my clients started developing a new web app in ASP.NET 2.0. After a couple of months into development, they decided it was taking too long, that the same app would take them 3-4 months to complete in ASP, and then they would migrate to ASP.NET 2.0.
I am wondering if there is anything they can do now in the new ASP app that would make migration to ASP.NET easier. For instance, would it be easier if they, and can they, use VS2005 to develop the new ASP app? Can they develop the new app over ASP.NET 2.0 and have the old ASP Server classes such as Server, Request, Reponse, etc., available to them? Or rather what will they not be able to do in the classic ASP way, in VS2005 and .net 2.0, that they could do when it was just ASP? What are the big hurdles that typically come about when code is ported from ASP to ASP.NET, and could they do something now, in the new ASP code base to prevent that?
Any info is appreciated.
Thanks.

You can do classic ASP style coding in ASP.NET 2.0, not that I'd ever want to. You can just open an aspx page and hack at it just like you did with ASP, but you lose a lot of the ASP.NET features. I'd see what they are having trouble with and guide them in the right direction for the new platform before I helped them take a step backwards like that. Also, Server, Request and Response are all there in ASP.NET it would be difficult to write any real application without using them, so that question makes me think they aren't understanding something about ASP.NET and are making things harder on themselves.
They are just delaying the inevitable by going back to ASP and it is going to take longer for them to do the port then they would have lost learning ASP.NET.

we have an issue where we recently reset a service account's password. the password begins with a special character (one of these !@#$%^&*()~). I was wonderingif anyone has ever heard of ANY of these causing issues with authentication when using a specified account for impersonation in a web.config file.
we keep getting this error:
Could not create Windows user token from the credentials specified in the config file
and it is locking out the account.

Have you tried using a pw that does not have a special character at the beginning, and tested it? Most password rules mandate a special character not being in the 1st position. Maybe there's a reason for it.
|

|
|
You learn something new every day. I was able to test it with another account that does not have a special character at all in the password and it works, but the problem with that is obviously we cant tell if the password or the account is the problem....
You have given me something to think about though.

How can I resize the dropdown portion of a fixed dropdown list when the user clicks the dropdown arrow with ASP.NET and C#.
|
|

When this question was posted before, I spent some time researching it and couldn't find a way to do it. I might be wrong, but it seems to be controlled by the browser.

Hello fellow developers!
I'm currently working on a website in which users should be allowed to log in. We have an existing user database (SQL Server 2000), and I would like to use this database along with the ASP.NET login controls. Is this possible?
I've been researching and found out that a possible solution would be to implement my own version of the MembershipProvider abstract class. Before I wander down that dirty dark road, I would like to know, if there is an easier way. I thought perhaps it would be possible to configure the SqlMembershipProvider to fit my needs.
We are unable to change the design of the database since it is part of an existing system.
Best regards
Soeren

If you're looking to use the existing database for login validation then all you need to do is handle the OnLogin event of the Login Control and authenticate against it. No need to implement a Membership Provider.

Okay. Looks nice.
I assume this is what you want me to do:
<asp:Login runat="server" ID="loginBox" OnLoggingIn="LogMeIn">
</asp:Login>
And in the "LogMeIn" function I should implement my login validation.
Can I be sure, that this will override whatever build in authenticate methods the login contol may have? The reason I'm asking is because the standard setup seems to work against some database in my App_Data folder, without any code at all.

Oh well stupid me just found out what I think you meant! 
The solution must be to inherit the Login class, and implement your own version of
protected void OnAuthenticate(AuthenticateEventArgs e)
Inside this you do your user validation stuff and set the "e.Authenticated" property to true - if the user validates of course - otherwise false.
It seems to do the trick for me.
If (I'm totally wrong)
please correct me! :-);
Best regards

Not at all what I meant.
1) Drop the login control on you page
2) Implement OnLoggingIn handler
3) Authenticate user in any way you choose
4) Call FormsAuthentication.RedirectFromLoginPage
Simple as that, no need to create a derived class
