If you work with a lot of RegEx expressions in .Net, here are two excellent resources:

Got my attention with the helpful tips for customizing the VS.Net environment:

There was a question in the DNN forums today about how to display a wait indicator while an IFrame was loading its contents. My solution:

<script language="Javascript">


function toggleProgress(progressId, iframeId)
{
     objProgress = document.getElementById(progressId);
     objIframe = document.getElementById(iframeId);

     if ((objProgress) && (objIframe))
     {
           objProgress.style.display = (objProgress.style.display == "none" ? "block" : "none");
           objIframe.style.display = (objIframe.style.display == "none" ? "block" : "none");
     }
}

</script>

<div align="center"><img id="<%= ClientID %>_ProgressBar" src="<%= TemplateSourceDirectory %>/images/progress.gif" style="display:block" /></div>

<iframe id="<%= ClientID %>_ResultsFrame" onLoad="toggleProgress('<%= ClientID %>_ProgressBar','<%= ClientID %>_ResultsFrame')" src="http://www.dotnetnuke.com" style="display:none"></iframe>

If you have nested ASP.Net applications, any HttpModules defined in the web.config of parent apps propogate down to the children. This can be desirable in some situations, but totally unwanted in others.

The easy way to eliminate the impact of parent HttpModules is to add a element in the child app's web.config. Sounds simple enough, until you try it.

Turns out that because of the way ASP.Net processes the web.config, even if you are clearing out HttpModules in a child app's web.config, you still need to have the requisite assemblies for the HttpModules in the child app's bin folder. Otherwise the child app will not run.

I have done quite a bit of research into online photo albums and somehow seemed to have missed one (my excuse: it's in beta). Check out Flickr. I like the U.I. ... very clean. The feature I really liked is the ability to comment within a photo by highlighting an area. They call it "Notes and Tags" which is a dumb label for an excellent feature.
