Mouse drag and drop fails

Fix problem with drag and drop not working in Windows. Have you encountered the problem in which you can no longer drag and drop files and folders in Windows Explorer (if you are using Windows 7) or File Explorer (if you are using Windows 10 or Windows 8.1)?

You can click and right click on files and folders, you can select files and folders, but you can’t drag and drop them anymore. We’ve encountered this issue ourselves and after searching for many possible solutions, we’ve found one which should work in most cases. Here’s how to restore the drag and drop feature in a couple of seconds:

Convert between Local Time and UTC or Zulu time

Here is some visual basic code for you!
You receive a ZULU time and want to store it in your local time?

Dim MyZulu As New Date(year,month,day,hr,min,sec,DateTimeKind.Utc)
Dim MyLocal As DateTime = MyZulu.ToLocalTime()

Or is someone or some API asking you for the next format in return, and all you have is a DateTime with your local time in it?

*UTC + offset as (YYYY-MM-DDThh:mm:ss+hh:mm)

System.NullReferenceException: ‘Object reference not set to an instance of an object.’

A happy error while coding in visual basic, vb.net
It is not the line where you get this error, but something that happened before, that made one of your variables invalid and unusable.

Read this. (@ NullReference Exception — Visual Basic)

Takeway API error

Try to get a new order for your restaurant from the Thuisbezorgd API with vb.net: simple 🙂
Create a WebRequest
Add some Authentication
Add the API key
run the GetRequest()
and…. BOOM!
The server committed a protocol violation. Section=ResponseHeader Detail=CR must be followed by LF

So what is it?

Descending Sort Order Thunderbird

I prefer my most recent emails at the top of the list. Unfortunately Thunderbird (and many other mail clients) do this different.
So how do I change the default sort order?
Change the advanced options!

If you want to sort all mail by Date, Descending (newest at top), change the preferences in the config editor to:

mailnews.default_sort_order:    default     integer      2
mailnews.default_sort_type:     default     integer     18

So, what does that 2 stand for? And why 18?

Teamviewer Connect greyed-out and disabled

What a week… sometimes things just keep going wrong for no reason. Today it was Teamviewer not giving me the option to connect to a remote PC to simply view their desktop and help the person with an issue they were facing. The option ‘Connect’ was just greyed out, not being able to enter an ID. Even the box on the top ‘insert partner ID’ did allow me to enter a number, but expecting that number to be added to the list, the ‘Connect’ option there did not do anything either.

The “Ready to connect (secure connection)” you see at the bottom of the window is also a little misleading there, because it does not want to connect at all!
So… what is the solution?
