Hiya all.
I hope this is the right part of the forum, because I couldn't see any other section where this might fit.
I'm trying to investigate why a specific website is crashing often.
The site is running on IIS 6.0 and .net 1.1.
My main suspect is that the site often throws "System.Threading.ThreadAbortException" (which are caught and logged) due to an apparently extensive use of Response.Redirects.
Now I've read on some MSDN article that IIS6.0 and .net 2 combined with this exception could cause the IIS thread pool to recycle and thus - well go down and cause the website to "reboot" loosing sessions etc.
But while this site is running on IIS 6.0 it is running using 1.1 framework. Does anybody have experience with the same bug while running on 1.1, or should I think outside the box.
Apparently the code has already been searched through for unclosed connections to the DB which shouldn't be the issue, and frankly, I can't see why DB connections should cause the IIS thread pool to be affected. If anything the system would just hang as far as I'd figure it.
Thanks in advance.

I have read that there can be a periodic problem when reading large varchar or text fields from SQL server (or memo fields from Access) using ASP--they can sometimes come up as empty strings. (See http://www.aspfaq.com/show.asp?id=2188.)
What I have been unable to find out is whether this problem is still around in recent versions of MDAC (>= 2.8). Does anyone know whether this problem still occurs--is it still necessary to follow the steps in that aspfaq article?

This is not a "periodic" problem that occurs sometimes. It's by design, and there is nothing unpredictable about it. Once you know how it works, you also know how to handle it. 
The data for blob fields are not fetched along with the regular result, instead they are sent in a separate stream. As they are sent in a stream, they have to be read in the exact order that they come in the stream. If you read them out of order, the stream will skip to the item that you requested and the skipped items are discarded.
The value is read from the stream when you request it, and the value is not retained in the current record data in the recordset. That means that you can only read the value once from the recordset. That is why you have to read the value into a variable if you want to use it more than once.
The blobs are sent in the same order as you specify them in the select statement, that's why you shouldn't use "select *".

b { font-weight: normal; }

That makes sense to me, but the reason why I'm wondering about it is because I have been using SELECT * with varchar(5000) fields without a problem. If I am understanding you correctly, this should not work if x is a large varchar (5000) field:
Set rs = conn.Execute("SELECT * FROM [tablename] WHERE [ID] = 30")
Response.Write rs("x")
Response.Write rs("x")
But for me it does print the contents of x twice. Do you know why this would happen?
|
|
|
|
|
Because varchar is not a blob field.
---
b { font-weight: normal; }
|
|
|
|
|
OK, so am I correct in thinking that none of these problems occur with varchar fields (only text fields)? The aspfaq article (link in original post) had mentioned that varchar columns with a length greater than 255 also had the problem; is this incorrect?
|
|
|
|
|
You only have these limitations for blob fields. Depending on the database or database driver, large varchar fields might actually be implemented or returned as blob fields, but I have never used one that does it that way.
---
b { font-weight: normal; }
|
|
|
|
|
Thanks for all of your help! How can I find out if my database/database driver is implementing large varchar fields as blobs? (I'm just connecting to SQL Server using SQLOLEDB.)

I am basically looking to see if anyone s familiar with configuring iis on a windows 2000 server to serve up PDF files, or if there is somehting that mayhave been turned on/off to prevent it.
it runs some aspx pages that output to pdf, but as far as the server is concerned, these are aspx files. it is up to the browser to determine the output format. however, if i try pointing to an actual pdf in a known web directory, i get "The page cannot be found"
any ideas?

If you're serving a PDF from an ASPX file, you must set the mime type before writing the file to the page, e.g.:
Page.Response.Clear();
Page.Response.AddHeader("Content-Disposition", "attachment; filename=[yourfilename]");
Page.Response.ContentType = "[your file type]";
Page.Response.OutputStream.Write(buffer, 0, length);

It serves pdfs from aspx files just fine. it seems to run normal web formats with no issue, even if they are outputting another format in the browser. the weird part is that any non-web standard file will not display at all. Basically, the standard web graphics and page formats work (htm, jpg, aspx, etc), and as long as that file extension is present, the file will load, but anything else (pdf, exe, doc) wont. i checked and no extra security has been added. its very confusing.
Luckily, these are only dev servers, but it makes me nervous to push anything to a production machien that i cant prove beyond a shadow of a doubt in dev.

Afternoon,
I just received this link from a friend who sits close to Microsoft.
http://www.microsoft.com/products/expression/en/web_designer/default.mspx
I'm sure most have you have heard of Expression but the lattest release of it has just gone live today.
What confuses me though is how does this fit into the grand scale of things. Do i drop Visual Studio or use it with this?? It seems to do most of the design work far better but I'm not even sure if you can add any programming to your projct using it.
Clue me up people...

How do the Microsoft Expression products interoperate with Microsoft Visual Studio®?
Each of the Microsoft Expression family of tools can be used together with Visual Studio for collaborative designer/developer workflow. Expression Graphic Designer provides output in a variety of industry-standard graphic formats (such as JPEG and PNG) for incorporation into Visual Studio projects, and designs can be saved as XAML, the markup language that describes user interface elements and media for the Windows Presentation Foundation.
Expression Interactive Designer shares the same project files as Visual Studio, and can pass both XAML and VB.NET/C# code back and forth between the applications so that designers can design the look, feel and behavior of the user interface. Developers can add functionality and build and deploy.
Expression Web draws on site functionality and Web services created in Visual Studio, and both products can be used collaboratively between designers laying out pages and developers building back-end functionality. ASP.NET 2.0 code and controls are fully compatible, and the design preview surface within both products is identical so that designers an

I need to capture the browser close event( when user clicks the 'X' button on top right) to confirm from the user if he wants to save the data on current page. I am able to capture the event by window.obeforeunload = ConfirmOnClose(this is name of function). Now when the user clicks on "Yes" to save the data, i use the method __doPostBack to call the server method to save my information. The problem i am faced with now is that a Default Message Box of window also prompts up to ask the user
"Are you sure you want to navigate away from the page.
Press Ok to continue or Cancel to stay on the current page."
This message box is not needed and i want to supress it.
I have tried to do window.opener='', but that also doesnot help.
I am using Asp.net 2.0 environment.
I need it very urgent. All suggestions will be highly appreciated.
i am pasting the code for reference:
function ConfirmOnClose()
{
if(window.event.clientY < 0 && window.event.clientY < -80)
{
if(Page_ClientValidate())
{
var result = confirm("Do you want to save the data in the form?")
if(result)
{
__doPostBack('ibtn');
}
}
}
}

If ddEurambieCCC.SelectedValue <> Nothing Then
msgMail.To= "webadmin@abc.com"
End If
If ddCastleGlenCCC.SelectedValue <> Nothing Then
msgMail.To = "ccceller@abc.com"
End If
If ddExcelsiorCCC.SelectedValue <> Nothing Then
msgMail.To = "cccepark@abc.com"
End If
If ddEllermanCCC.SelectedValue <> Nothing Then
msgMail.To = "cccexave@abc.com"

Hi
AS per my understanding your problem is that you have to send the email to all the mail address which are selected in 6 dropdown list. If 5 of them are selected then you have to send 5 mails.
If that is the case then you have to create one mail object for each selected droupdown and then in each if condition you have to send the mail for each mail address if the values are selected.
Please let me know
Regards

Cant we actually add to CC with single mail object for eg.
if ddSelectone.selected <> nothing then
mailobj.CC = 'abc@test.com'
end if
if ddSelecttwo.selected <> nothing then
mailobj.cc = 'abc1@test.com'
end if
and so forth
please advise. why my this logic isnt working
