Why do people insist on catching errors they don't know how to handle then throw away useful information!
I would suspect that you shouldn't be getting a data type mismatch error at all, so why are you catching it here... Oh... I see because it it the button click event handler...
Why do you have database code in the presentation layer?! You'll be glad you don't work for the company I work for. It is written into out coding standards documentation that the use of data access code in a windows or web form is a sackable offence.
First, comment out the catch block. Find out exacly what is causing the exception and fix it.

This was surely not production code ? The giveaway is that the button is called Button1....

It wont be "production" for another 6 months. Again, though I bulid data collection websites for the govt. I have trained users, and on a secure server, that only my users have access too. The actual website, will be used for about 2 months, and then, never used again, and I will start another project.

1 - all your code is ripe for SQL injection attacks
2 - As has been said, you should never have DB code in your presentation layer
3 - As has been said, why catch exceptions and do nothing ?
4 - use string.Empty over "", as it's more efficient
5 - Give your controls meaningful names. When someone else looks at the code, how do they know which button was button1 ?

Even better: assign null to the reference. That way if you try to use the value without assigning it a usable value, you will get a null reference exception instead of a cryptic error from the database.
Alternatively, add a default case in the switch, where you throw an appropriate exception. That way you don't have to assign anything to the variable before the switch statement, as the compiler knows that the variable always has a value when you exit the switch.

2. Why should you never have DB code in your presentation layer?
3. Actually, that is my most recent problem, the exception is catching an error, every value is updating the table, yet the exception err, is throwing "cannot find table 0"
4. I didn't even know you could do that, you would think the people that I work with that have degree's would code the write way, I guess not!
5. Eh, button1, I normaly do, this page actually only has one button it. I just hadn't gotten to renameing it.
Here is the most recent of my button1click,

Dear all,
I managed to return a full hyperlink with query string values from a database as a string and i bound it to a grid view HyperLinkField
My problem is that i want it to open as a pop up when clicked not to navigate withing the same page
I know i should use the window.open javascr5ipt function but i don't know where should i put it
I would appreciate any help or hint 
Best Regards

If you are returning an anchor tag then you just need to set the target to _blank
<A HREF="yoururl" target="_blank">
Hope that helps.

Looks like the error is to do with the object user. Get the value of the userid and role into a string, debug and check if its got to do with the object user.
string strUserID = user.UserID;
string strRole = user.Role;
strWho="Welcome "+strUserID+" you are logged in as "+strRole+" the date and time is now"+DateTime.Now.ToShortTimeString()+", "+DateTime.Now.ToShortDateString()+".";

Hi Developer
I have performed simple screen scrapping(reading contents of other website) many times. But now I need to go a bit advance...
Like if you visit: http://home.scci.com.pk/search.asp[^].
Now from that page I can grab 20 companies using "HTTP requests object" BUT I need to grab all the companies(20*784). Please note records changed while we change drop down list "Display Page".
Any Idea how to achieve this???
Lets work it Out.........!

You can do this by creating a windows based application by using AxSHDocVw.AxWebBrowser active x object. You need to follow following steps.
Step 1 - Grab the required page using the WebBrowser Control.
Step 2 - Using MSHTML we can locate various form fields, get the data of the current page using MSHTML.
Step 3 - Now locate the page dropdown list in the page get the selected value increment by 1 and fire the click event of the go button.
Step 4 – Repeat step 1 to 3 until you get all the data.

I'm using an ASP.Net menu control in a CSS controlled layout web application. The menu control and datasource are in a div in the Master page.
The problem I'm having is the menu items displaying underneath the controls in the Content Page and I don't seem to be getting anywhere by tring to set the z-index of items, (although I havn't gone completely gone down the tree of controls rendered by the .net framework yet). I'm also only looking at in IE 6 at the moment due to work constraints but will give it a go in Firefox tomorrow to see how it renders but in the meantime, has anyone else encountered this, have you found a way around it and if so how?
It's starting to drive me quite insane  now so any help or pointers are greatfully appreciated...
...cheers!

I was experiencing some wierdness with menu controls in IE 7. What was happening to me was that the sub-menus of the menu control were appearing about 200px right of where they should have been.
What worked for me was to set the DIV containing the menu control to position:relative.

We have an online library with thousands of 'content collections' using a out of box solution call NXT. There is a small help 'application' developed in house that handles foot notes and that sort of thing. There are links in the document, which calls this little asp application, which returns content from a separate database. I am in the process of rewriting these asp pages in .NET 2.0 and adding functionality (new methods of searching, etc). Now, updating every single link in every single content collection to link to Search.aspx rather than Search.asp is not feasible. So I thought I would write an httphandler to internally redirect requests to .asp pages to .asps pages. The problem is I only get blank pages now, I can debug and step through the handler and everything seems ok. Here is the ProcessRequest method from the handler:
public void ProcessRequest(HttpContext context)
{
string url = context.Request.Path + "x";
if (context.Request.QueryString.Count > 0)
url = string.Format("{0}?{1}", url, context.Request.QueryString.ToString());
context.RewritePath(url, false);
}
And the web.config section:
<httpHandlers>
<add verb="*" path="*.asp" type="Project.HttpHandlers.AspToAspx, Project.HttpHandlers" />
</httpHandlers>
I'm sure I'm missing something simple. Thanks in advance.

Hey all,
I would like to know what is the best way of doing this. I just need the user to enter in some information, including their email address, and let the user's email that they enter in the text box be the address that the smtp function uses to send the message. This form is on our intranet, so it accesses our internal smtp server, which does not require authentication. I have some code that I think might work, but not sure what I should have set in my web.config to allow for something like this.
Any help would be great.
Thanks!
