Microsoft JScript runtime error: 'null' is null or not an object

by filip 28. May 2008 12:44

Programming JavaScript can be fun, but sometimes when I get errors like this it can get a little frustrating...

 

It happened on the following line, where the variable 'o' was null:

o.onmousedown = Drag.start;

Flash standalone installer for internet explorer (IE MSI)

by filip 20. May 2008 13:14

I'm not sure why Adobe makes it so hard to install the flash player with a MSI.  By going to adobe.com and clicking on the "Get Flash Player" link, it will direct you to a page that automatically will attempt to install Flash in IE.  I needed a MSI because I needed to install Flash on a machine with restricted internet access.  Fortunately, even though they don't advertise it, you can get a standalone installer for IE as well...

'AjaxControlToolkit' is undefined (javascript)

by filip 8. May 2008 13:14

I got this annoying error recently in a website I've been working on.  It worked perfectly fine locally, it worked fine after uploading to the web server on my machine and other machines in the lab (various browsers).  Then, it turns out, it doesn't work on (one of) the client's machines.  Of course, I'm unable to replicate the error locally.

I looked around and it seems the first solution was to clear the cache.  A lot of people said that Ctrl+F5 works, others said they needed to manually clear the cache and then restart the browser.  Well, neither of those worked.

Fortunatelly, the solution turned out to be pretty easy:  Set the "CombineScripts" property of the ToolkitScriptManager to false.

 <ajaxToolkit:ToolkitScriptManager runat="server" ID="ajaxScriptManager" EnablePartialRendering="true" CombineScripts="false" />
