Hello All,
I've been reading about Login Controls and I'm planning to practice using them, however I've come across a stumbling block. The article that I've read did not say anything about a database being involved and I'm pretty sure a database is going to be needed to store users' info before users can login. Also how does the Login Control know which database will be used to check the entered login info? Thanks in advance for your help.

I would always write my own login control. However, the control that's built in, fires events, you check with your data source to make sure the login is OK, and let the control know. The control also won't magically make it that a user can't view your pages without first logging in.

Here is what I'm trying to do: I have a MasterPage with a couple of HtmlAnchor controls, like this:
<a runat="server" href="~/About.aspx" onserverclick="HtmlAnchor_Click">About</a>
All I want that in the HtmlAnchor_Click method to modify the attribute of the control and remove the link from the anchor (modify the InnerHtml). But when I try to do that I get the error from the title.
Here is how I'm trying:
protected void HtmlAnchor_Click(object sender, EventArgs e)
{
HtmlGenericControl ctrl = sender as HtmlGenericControl;
string innerHtml = ctrl.InnerHtml;
}
Anyone hints?

Why do a postback ? I would do this in javascript.

You can only use the InnerHtml property if the actual type of the control is LiteralControl or DataBoundLiteralControl, but your control is an HtmlAnchor.
If you want to change the contents of the control, clear the Controls collection of the control, then add a LiteralControl with the text that you want. Alternatively, if you know that it contains a single LiteralControl, get the reference to that control from the Controls collection, and change it's text.
Despite everything, the person most likely to be fooling you next is yourself.

Try this,
<a runat="SERVER" href="~/About.aspx" onclick="this.innerHTML='';">About<;/a>
Why are you wanting to do this? If you just want to hide the control you can use .Visible = false;

No, I do not want to hide the control. I just want to remove the link when that page is active where the anchor links to.

Use this inside your page_load of the master page.
string s= Page.ResolveUrl(LinkControl.HRef);
string u = Request.Url.AbsolutePath;
if( s == u)
{
LinkControl.HRef = "";
}
You can apply this logic to all of your links.

I am trying to build a form using ASP.NET that will both send the form results to a database and email those results to a specific person. For example my form would include at least these items:
1. From Organization
2. Order Number
3. Responsible Organization Email address
4. Reason (Memo format)
I want the user to click a button and the data be sent to a database and also email to whatever address is ented into 3. Responsible Organization Email address.
Is this possible via ASP.NET edited using MS FrontPage?

Ok, I am still trying to learn ASP.NET so not sure that this article from really assists me at this stage.
Does anyone have some basic sample code showing an ASP.NET form posting results to a database and emailing them to someone as well?

fair enough. I suggest you don't look for an example of doing both. One of each and then you try to put it all together. There are a massive number of .NET Database articles here on code project and I would guess there are one or more about sending email as well.
You can find the articles under the "CHAPTERS" section in the menu bar of the site on the left side of the page.

The email part is pretty trivial. ASP.NET also has automagic DB insert stuff that no professional dev would use, but that is perfect for your situation ( it writes a lot of the code for you ). I'd second the other response, look for articles on the DB stuff first, then worry about the email.

hello all,
I'm getting this error when connecting to my sql server 2005 with asp.net 2.0
An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Shared Memory Provider, error: 40 - Could not open a connection to SQL Server) (.Net SqlClient Data Provider)

Enable the remote connections in SQL server surface area management. Make sure you don't have any firewalls running which blocks SQL server port.

Avoid using SQLDataSource. Write your own code which gives you more flexibility.

Hello all,
I posted a question recently on using a SDK from an ASP.NET application and got some answers that made me rethink how i should approach an application i need to build.
Basically I have an ASP.NET application that needs to interact with a piece of hardware when either a user wants to interact (they tell the hardware to do something e.g. turn on turn off) or periodically (we poll for information from the hardware). Unfortunately the SDK only allows one call at a time so I need to provide my own locking around the SDK to ensure firstly that two asp clients attempt to interact with the hardware at the same time and secondly that a user doesn’t try to interact whilst a periodic action is taking place.
After some research and some questions on various forums I have decided to create a windows service which will create static instance of the SDK and the call these methods from the ASP.NET application through IPC remoting channels. From what I have read I will need to create two DLL’s one to interact with the SDK and contain the business logic and a DLL which will be used for the remoting objects.
Am just wondering if this seems the most logical way to tackle this problem or if anyone can think of a different/more efficient way or can see any holes in my solution. Am completely lost by this now as i can't find any examples of doing this it all seems to be about using web services but because i want to keep the state of the SDK object i didnt think i could use these??!!
Thanks,
Adam

I have a page with nothing but buttons and the only thing they do is a response.redirect(" ") to which ever page. If I let it sit still for roughly 2 minutes and hit the return key I get a blank page. Can anyone pls help me trouble shoot this problem.

I assume you never redirect to an empty string. What is the code ?

one button may do a response.redirect("report1.aspx") and the return button does a response.redirec("reportsmenu.aspx")
