They look different, the only issue you will have is that sln files will open in 2003 if you double click them.

I am sorry for stupid title, but I don't know how to name the thread.
Anyway, I am working on a web admin panel and I have a problem about object reference.
I know what this error mean, but what I don't know is why I reload some page 1000 times and I try to reload it 1001 time, and I get object reference?
Sometimes is on if (dataReader.Read()) and sometimes on if ((bool)Session["SomeText"]).
Can session be abandoned this way?
Before this if's, I have another if (in session_start in global.asax) that verifies whether session is null or not.
Does anyone have an idea what could be a problem?

I guess if your database connection fails, you get a dataReader back that is null, and you're not checking it. And, I guess your session must be timing out. I always check if a session variable is null before I try to convert it to anything. In fact, I'd tend to wrap it in a property that does exactly that, so it's written once and used every time.

I've added check if connection is opened, but unfortunately, I have to wait to see if error comes again  , but I definitely have to change some things in my code.
Your session property sounds great. I have to implement that.
Thank you Christian and best regards.

It will load, you just need to click a few times. Your problem ( as you'd notice if you set some breakpoints to try to debug your code ) is that page_load occurs BEFORE your events fire. You need to set the imageURl inside your event, or in the prerender event, which fires after click events.
And, please tell me you are not writing a project with a control called ListBox1.

Hi dear.
my question from host admin :
((((
I recieve this error in my site :
Exception Details: System.Web.HttpException: Validation of viewstate MAC failed. If this application
is hosted by a Web Farm or cluster, ensure that <machineKey> configuration specifies the same
validationKey and validation algorithm. AutoGenerate cannot be used in a cluster
I recieved this error in some different situation. this site worked in another host with out any
problem. I recieved this error in my onother site in your hostI think there is a
problem in web.config
}}}}
and host admin response:
(((
This is a bug of Microsoft, when you use some data controls of .net, in some case like post back
when data load not finished reading from database it will be happen.
And you can disable viewStateEncryptionMode on your web.config or your pages that issue happend,
but
it will be less safety for your data, but it is the fact, so it's up to you, or you can wait
MS
to fix it.
)))
I dont know what can I do now. how I can solve my problem.
please help

Do what you were told to do, add the attribute to the page that turns off view state encryption.

do you know correct syntax of this attribute?
|
|
|
|

Relying on intellisense, which shows you all the options if you just look, I'd guess it's one of these:
ViewStateEncryptionMode="Never" EnableEventValidation="false"

If this is a microsoft bug, there is an article about it. Did you get any link to such an article from the host admin?
Despite everything, the person most likely to be fooling you next is yourself.

Hy guys, I have a question about images in SQL databses.
When I am in database table viewer in Microsoft Visual Web Developer 2005 Express Edition and I am entering data into the table, how do I insert image into the image-type field? What are the pre-conditions for inserting a picture (which is on my hard drive) to image-type field in database?
Thank you for your time.
Cheers

I am not sure if that's what the image type is for, because your DB will have no idea if the byte array you pass it is a bitmap. Have you googled for info ? I would suggest the best bet is to store the image in the file system, and store paths in your DB, but there's no reason you can't store the image data in your DB.

And what about the Gridview control. I know I can use it to display data from database very easy. And if the table in the database contains images will the gridview control display it automaticly as it does for the other fields?
|
|
|
|
|
|
Convert image in to binary data and store into the database.
and whenever you want to access the image from the database, read binary data from the database and create .bmp file

Hi Friends,
Can any one help me with my website(http://www.sharetosave.co.uk/[^]) connection it gives following error when I upload it to the server i.e. hosting company server.

Everything runs fine on my local server.
Web hosting company says that MySql.Data.dll is in GAC and I need to put reference i web.config
I put that Reference as follow.
<add assembly="MySql.Data, Version=5.0.7.0, Culture=neutral, PublicKeyToken=994bc1102e243463">
Can any one help please? Its been more than 2 weeks between me and web hosting company we are unable to resolve the problem.

Do you know how you search on google or yahoo, msn etc.. and type in a certain phrase,lets say "blue cats in florida" how do I get that phrase on my landing page without having to type the phrase ? Does anyone know what I mean ?
Thanks !

Do a google search, then look at the URL, the way to build them is pretty straightforward

hi scm22ri,
Any search engine (Google, Yahoo, MSN) basically works on the Meta tag of the any webpage. For ex:- If you feed any query to Google, then Google first searches Meta Tag, Title, Contents of the all the web-pages. Then make a bunch of all the related web-pages, after that rank the web-pages based on thier relativeness to the query.
There is one article based on Search facility. Just check this link.

Hope this will help you.
Thanks & Regards

Hey all,
I have a TreeNode, and I'm trying to set the NavigateURL to call a JavaScript function of mine.
When I do:
node.NavigateURL = "javascript:alert('123');";
It works fine, but when I do:
node.NavigateURL = "javascript:myfunction('123');";
Nothing happens... here is the JavaScript function I'm using (if it helps):
<script type="text/javascript">
function myfunction(page)
{
alert(page);
}
</script>
Can anybody see what I am doing wrong here?
|
|
|
|
|
|
On the definition, it doesn't say anything. But on other parts of MSDN and the ASP.NET forums, it says to use "javascript:void(0);" inside the NavigateURL, so I took the presumption that I could call JavaScript functions this way.
If this is the wrong way, could you please tell me what is the correct method for calling JavaScript functions from clicking a TreeNode, please?
[EDIT]
I have also found this:
http://www.codeproject.com/KB/XML/sqlxmltreeview.aspx
Which makes use of JavaScript in the NavigateURL, so it would appear it's the commonly used method, how-ever I cannot determine why mine will not work. I'll need to get myself a JavaScript debugger if nobody is sure.
[EDIT]
I got a JavaScript debugger, and found the problem lied within my JS function, I had a small typo in there, which crashed the entire function. After fixing the typo, the method works perfectly.
