ProcessStartInfo print verb does not exist for .tif images
We have a piece of software that attempts to print .tif images using a ProcessStartInfo object. It sets the Verb property to "print" and the FileName property to the path of the image.

Encrypting connection strings so other devs can't decrypt, but app still has access
I have a database that I want to access via a .NET web application. I can encrypt the connection string in web.config easily enough, but any developer with access to the box can decrypt it with a few lines of code - they have access to the box, so therefore have access to the encryption key stored in machine.config. While I can lock peo...

Clear cache in SqlDataSource
I need to manually clear the cache on a SqlDataSource with caching enabled. I've tried setting EnableChaching = false, and CacheDuration = 0 (as well as = 1) and none seem to expire the content already in the cache - although they do seem to prevent new SELECTs from being cached. How do I manually expire that cache? Thanks. ...

Correct useage of OnClick vs. MouseClick events in Winforms using C#
I have a custom control I'm currently developing and realized that my code was being ran twice. Not really a huge issue (it is only a Focus method call) however I would like to understand it.
