.NET Error: httpRuntime requestValidationMode=”2.0″

Posted on October 23, 2012December 3, 2013 by ellen

If you get .NET errors that reference

<system.web>
<httpRuntime requestValidationMode="2.0" />
<!-- everything else -->
</system.web>

It means that the application you are trying to run has set the property requestValidationMode to function the way it acted under .NET 2.0, but this directive only makes any sense under .NET 4.0 or greater, and your website is not set up to use .NET 4.

You need to run the application in a separate application pool and set it to run under .NET 4.0 (which, of course, needs to be installed before it can be used).

Thread: Changing maxAllowedContentLength

Posted on November 22, 2011 by ellen

In a .NET application used to deliver quizzes, attempting to import a large quiz from another server resulted in this error:

“The request filtering module is configured to deny a request that exceeds the request content length.” A second message stated:
“Request filtering is configured on the Web server to deny the request because the content length exceeds the configured value.”

Enhanced RSS Display script in classic ASP

Posted on October 20, 2010 by ellen

A very useful displays an RSS feed as a list of article excerpts within a webpage.

The screenshot below shows the way the original script displays the RSS feed. A list of article excerpts is displayed in the center column of a portal site..

VB error: Object required: ‘[string: “foo”]’

Posted on October 20, 2010 by ellen

When writing a script to display an RSS feed, I got the following error:

Error: Object required: '[string, 136]'

This is because I was using the SET command to create a string, as shown below:

Dim itm itm = lnk.link Response.Write(itm) Dim itmid Set itmid = Split(itm,"=")(1)
resulted in the error

Error: Object required: '[string, 136]'

Create an iCal file from your data using ASP

Posted on June 23, 2010 by ellen

Google Calendar and many other calendar apps will import or subscribe to iCal format files (.ics) If your event data is locked away in a database, you may find it useful to display and distribute it using Google’s extensive calendaring features.

Following is an example of an ASP file that will write an iCal file.

Generate the iCal file in a web-accessible directory, then have Google Calendar or other iCal compatible application subscribe to it.

Set up a Cron job in Windows to run an ASP script

Posted on June 23, 2010 by ellen

If you are used to Linux environments, and working on a web application which needs to execute a function at regular intervals, you’d use a cron job. On Windows, you’d use a scheduled task instead. There is one part of the process that isn’t obvious, so here are the steps involved:

Create the web page that executes the desired tasks – sending email, creating files, etc. For example, I have some ASP scripts that create RSS and iCal feeds from a proprietary database, that need to run daily. Record the URL for later.
You will also need a domain account that can run the task, or a server account that can be used in perpetuity to run these types of tasks. I usually have a “fake” account that will never expire created for this type of thing.

Umbraco installation error: The virtual path ‘/install/steps/welcome.ascx’ maps to another application

Posted on April 21, 2010 by ellen

After installing “Umbraco,” you may get the following error:

The virtual path ‘/install/steps/welcome.ascx’ maps to another application, which is not allowed.

This is because you have installed Umbraco in a virtual directory (not at the web root of the “Default Web Site” in IIS terminology). It is a path problem, easily corrected by fixing the paths in the web.config file.

Umbraco installation error: Unrecognized attribute ‘restartOnExternalChanges’

When using Microsoft’s Web Platform Installer to install Umbraco on a Windows 2003 server, everything seemed to be going right until I tried to view the site. I saw only this error message:

ASP contact form for use on GoDaddy sites

Posted on July 15, 2009 by ellen

UPDATE

The form described below works, but if the user’s email address is from hotmail, yahoo or gmail, GoDaddy will still block submission of the form. So here is the solution:

Make the following changes.

You will no longer need “formproc.asp”. GoDaddy will not release the code for their working form but you can use theirs.

In contact.htm, replace everything within the FORM tags with the following HTML code. This sends the user’s data to GoDaddy’s ASP form processor, _gdForm/webformmailer.asp

<form action="_gdForm/webformmailer.asp" method="post" id="form">
<input type="hidden" name="subject" value=&quot;Submission" />
<input type="hidden" name="redirect" value=&quot;thankyou.htm" />
<table cellpadding="0" cellspacing="0" summary="Contact form">
<tr>
<th><label for="name">*  Full Name: </label></th>
<td><input type="text" name="name" id="name" size="25" maxlength="255" /></td>
</tr>
<tr>
<th><label for="email">*  Email Address: </label></th>
<td><input type="text" name="email" id="email" size="25" maxlength="255" /></td>
</tr>
<tr>
<th><label for="subject">Subject: </label></th>
<td><input type="text" name="subject" id="subject" size="38" maxlength="75" /></td>
</tr>
<tr>
<th><label for="message">Message: </label></th>
<td><textarea cols="30" rows="6" name="message" id="message"></textarea></td>
</tr>
<tr>
<td colspan="2" id="button"><input type="submit" value="Send Email" /></td>
</tr>
</table>
</form>

Next, create a “thankyou.htm” page, which can contain any message you want. This is going to be the page they get redirected to after the form has been processed.

GoDaddy made some changes to their smtp email server settings such that old ASP mail forms no longer work.

Escape double quotes in strings in Visual Basic

Posted on February 25, 2009 by ellen

I use Javascript much more than visual basic, so I’ve always been puzzled by how to escape nested quotes in strings in VB. In Javascript, you either nest single quotes (apostrophe’s) and double quotes or
