Hi Can you please tell me about the free / open source blogs available in ASP.Net 2.0
Any database will do.
Please provide links if possible.

I'm developing a fairly largish project in VS2005 sp1 (asp.net). A problem I'm having at the moment is that it intermittently displays the error
“Unable to copy file ‘obj\Debug\xxx.dll’ to ‘bin\Debug\xxx.dll’. The process cannot access the file 'bin\Debug\xxx.dll' because it is being used by another process.”
some pepole on internet tell me config in webconfig is:
<hostingenvironment shadowcopybinassemblies="false">
but it still error some body help me ????

Hi
Uncheck read-only of your main folder (right-click your bin folder -> click properties -> uncheck read-only if it is checked) and redo the steps again.

Hello,
I have an ASP.NET page and in its runtime code I am trying to get an
user profile, change it and save it.
It works if I use Profile, which is the profile for the current
authenticated user. But I want to change the profile of another user.
Anyway, I am using:
1 Dim pcProfile As ProfileCommon =
CType(ProfileCommon.Create(Username), ProfileCommon)
2
3 ' Update personal
4 With pcProfile.Personal
5 .Blog = tbBlog.Text
6 .Homepage = tbHomepage.Text
7 .Name = tbName.Text
8 End With
9
10 pcProfile.Save()
This is not working.
What am I doing wrong?
Thanks,
Miguel

I have a website written in vb.net. The SessionID keep changing everytime i refresh the page
Response.write Session.sessionID
Has anyone got that problem before?
Please help, I am so stress now.
Regards
Nick
P.S I create the another website on the server just to printout the SessionID and it works just fine ( no new value when the page was refresh)
|
|

|

Hello Nick,
The SessionID keeps changing when no data is assigned to the Session Object. When you assign a value to the Session, the SessionID will not change.

I have a business related intranet site written entirely in asp, note the conspicuous absence of the letter x. I, when I say I in this context I mean our security team, have decided it would be a good idea to handle security through active directory. The aspx code I, I meaning me, have written pulls back a domain and username quite nicely. I would like to do a little database authentication, not a problem, and based on the outcome set a few session variables defining access rights and redirect the user to the old asp pages I have in place.
I have tried both the response.redirect("somepage.asp") and the server.transfer("someotherpage.asp") and they both blow. Can I not get from aspx back into the asp world?
Any help would be appreciated.

I required a web method to be present inside a user control that I have built for my site. The user control contains the new Ajax AutoCompleteExtender which requires use the web method to get it's predictions for the user. I originally built the code straight into a page but it is now required in several other pages so a user control seemed like the way forward. It worked fine in the page but once in a control it seems to go wrong.
Im not sure if there is some sort of permission issues here or what but I would appreicate some help on this. Thanks

What exactling is messing up when you put it in the user control?

Hey. The issue I'm having is the same if
A: I try to put the web method code in a seperate web service file
B: I try to put the web method code in the code behind file of the user control
I get the following Javascript error once you begin to enter text in the textbox itself.
Message":"Authentication failed.","StackTrace":null,"ExceptionType":"System.InvalidOperationException"
I'm guessing that for some reason or another the Javascript from within the page cannot find the web method in whatever place it is residing. I am using ServicePath="WebService.asmx" to try and point it in the right direction to no avail.
Any ideas?

I'm trying to validate user input on the client side. The values needed for validating the user's input should come from the database where i have a RANGES table. I don't want to expose the user to the table but i want to use the table's values "behind the scene".
Does anybody if and how this can be accomplished?
Thakns a lot in advance.
Snir.
