Creating a Virtual Hard Drive from an Existing Macine

This shows how to create a VHD from an existing non-virtual PC.

For windows XP or greater it is very easy.

Disk2VHD is a free microsoft utility that runs under windows and created a VHD on the same computer, that is a model of the machine. This can be attached to a virtual machine in Virtual PC and started. All that is required is sufficient disk space on the machine to create this VHD. On the first machine I tried this on it took a few hours to build.


For Windows 2000 and older this approach will not work.
I am testing a shareware utility called WinImage (winima85.exe)
This did not work either.

Final course, I am going to pull the HD out of the laptop running windows 2000, plug it into a Windows 7 machine, and use Disk2VDH to clone it from there.

Unknown server tag telerik:grid

When trying to open aspx forms that contained Telerik controls I received the error message, "Unknown server tab telerik:grid". My colleague was able to open thse

We tried cleaning and rebuilding, opening and closing the project, which made no difference.

Then we noticed that in the solution explorer there were warning symbols against the telerik references.

My colleague had referenced the Telerik controls from the bin folder in the solution, but this folder had not been checked into source safe.

When my colleague added the bin folder to source safe, and I rechecked the code out, all worked fine.

So the answer we have found is to make sure that the Telerik dlls are in the project binary folder, and to reference them from there.

A similar problem occurred when the project refused to build. This was solved by adding a blank form, and dragging one of the telerik controls onto it.
