SmtpServer is obsolete in .NET 2.0, you shoud use SmtpClient.

Check MSDN documetation.

I have a working sample on a diffrent computer But my internet "died" there.

this is an article on cp using 2.0.

Did you tried to get what is in InnerText, before assining a value, the problem coud be before assaining value. Note that i can't try, because i dont have accsess to my pc.

Did you checked you gave app.config write permision?

you've commented out the line that opens the recordset - does the error make more sense now?

i commented it because it came up with another error : ADODB.recordset arguements are of the wrong type, are out of acceptable range, or are in conflict with one another. Any ideas???

You haven't told the recordset to use the connection you've just opened...

Yep, you opened a connection and then tried to open a recordset but you didn't associate the connection with the recordset. I forget the asp syntax off the top of my head.

objRS.Open "tblusers",objConn, adLockOptimistic, adCmdTable

this shud be the way to open the Recordset.ie the second parameter shud be the conenction object rather tan Locktype etc.

by the way u shud use an open sqwl statement other than the tblUsers in open statement ok.

ContentPlaceHolder Masterpage Issue

Hi,
I have a ContentPlaceHolder that is in a masterpage. I have a drop down in my masterpage, and this I am using to try and change certain details in the page(contentplaceholder). My issue is that when the dropdown's selected index event causes the postback (event in master page), it goes into the placeholder code first, before moving out into the masterpage, which seems highly incorrect to me 0_o.
any help on this would be greatly appreciated.

Re: ContentPlaceHolder Masterpage Issue

ToddHileHoffer19-Oct-07 2:37

My sugesstion is to put the code in the content page (since you are trying to change the content page) and add a handler for the dropdownlist's event in the content page.

<br />
 <br />
        protected void Page_Init(object sender, EventArgs e)<br />
        {<br />
            DropDownList ddl = (DropDownList)this.Master.FindControl("DropDownList1");<br />
            ddl.SelectedIndexChanged += new EventHandler(DropDownList1_SelectedIndexChanged);<br />
        }<br />
<br />
<br />
        protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)<br />
        {<br />
           //Put code here<br />
 <br />
        }<br />
<br />

I didn't get any requirements for the signature

thank you very much it works hundreds ^^. I've also used an AJAX Update Panel that effectively Fires the event first, then carries on. I'm wondering which would perform better though =/. curse my curiousity.

Horrendous Bug in ASP.NET Session Handling

Vasudevan Deepak Kumar19-Oct-07 2:07

19-Oct-07 2:07

I am encountering a really horrendous bug in ASP.NET session. I would like to give a brief step-by-step on what I am doing.

1) An HttpHandler/Module is involved from an IFRAME to do some important and long-running activity.

2) To keep a COM ISAPI authentication software and ASP.NET also aware that there is a genuine request being processed and the user should not be kicked out, we have another IFRAME to ping a dummy .ASPX page periodically using a META Refresh tag.. We chose an ASPX page so that both the COM ISAPI and ASP.NET would get satisfied by validity of the requests.

3) The Web.config directs SessionState to be SQL Server and is configured with an expiration of 20 minutes. [It has been ensured that SQLServer Table keeps getting new values on every hit of the dummy ASPX page.]

Inspite of actions taken in (3), ASP.NET keeps forgetting the following values on the 21st minutes:

1) A few or all of the Session variables.
2) A few variables used in the HttpModule are NULLed. [They are in use. So I don't think how does GC get an indication to sneak in to gobble them]

Can somebody point out where is the mess up happening on why ASP.NET is forgetting session variables? I would like to add on that there are no recycling of worker process too.

Just taking a stab here, but make sure all the caching is turned off for the dummy.aspx page. I have a feeling you might be getting a cached version and not satisfying the needs of the session.

Read the image value to a byte array. Set the response content type to something like Response.ContentType = "image/gif"; Use Response.BinaryWrite(byte[]) to send this to response.

You can do it two ways:

1. return the both values separated by some special character like |-| and then split it in the parent page.

2. you can set the field of the parent window from within the modal dialog box like:
top.opener.document.getElementById('field1').value = field1;
top.opener.document.getElementById('field2').value = field2;

In the declarative catalog part i have a image control. When i add the image in webpartzone in the catalog displaymode at runtime, The image control is displayed without the image.
Similarly in dropdownlist, the list items are not displaying.
