If I got your question right, you're trying to putBeeper put times, which is done by the following code:

For anyone trying to produce single exe on azure in the future, this is yaml that actually works (I am positive there is a cleaner, more straightforward solution, but I wasn't able to find it):

For situations like these, I find it's useful to use Ember.Evented and the pub/sub pattern.

The components use dependency injection to receive an instance of the service and in their constructor (or elsewhere if needed), they subscribe to some "topic" on the service. Consider an example where a publisher service generates ticks at a consistent interval. In our component, we want to subscribe to the updateTick topic and increment our current tick value each time the event is triggered.

The problem with that code is that facingWest() and facingEast() don't seem to be functions. Instead, they're properties, so use facingEast and facingWest (i.e. use them without brackets). That gets rid of the error but facingEast and facingWest are never true based on my testing, which means you can't make it turn based on that.

So, I think you'll have to write some code that doesn't rely on the facing commands. As long as you can assume that Karel starts at the bottom left of a grid, you can just turn when the front is blocked, starting left and then alternating to right. Something like this should work, you'll just have to edit this to make sure it doesn't tell you front is blocked at the end of traversing an even-numbered grid.

You can try this XPath-1.0 expression:

You can't get an int value out of a None. Instead, use the int value you got from your function. Change this:

I don't understand what you are trying to do, but the issue is that all the information in your image is in the alpha (i.e. transparency) channel. I can demonstrate that by splitting out the R, G, B and A channels using ImageMagick in the Terminal like this and laying them out beside each other:

Once Hollow said something about the code for any size, I finally got it. Thanks. Here is my code:

if people typ 3 in the textbox B3 + 3rows needs to be visibele and the rest needs to be hidden.

First hide all rows in the range and then show only the relevant rows. I am assuming that the name of the textbox is TextBox1. Change as applicable.

Is this what you are trying? (Untested). Also I have not done any error handling. I am sure you can take care of that?
