QUESTION
I really hope I haven't gone down a dead-end here. I have a Behaviour that gives the currently selected Color, and the current mouse coordinates, then carries out a task when the mouse is clicked. That task involves looking at a list and then updating the values in that list, for it to be retrieved later. The fact that I can "store" the selected color gives me hope that storing a list can be done in a similar manner. I'm just at a dead end and not sure how to solve this. Would really appreciate some help.
...ANSWER
Answered 2022-Jan-17 at 16:02Full credit to this response from duplode, I'll just go through how it was solved:
Let's say we have a function that modifies a list somehow, depending on some value. How/why updateMyList
modifies the list doesn't really matter for this explanation, we just need to know its type. For this example, we'll say the value that determines how the list changes is a mouse coordinate tuple (x, y), which we'll pass as its first parameter:
QUESTION
I'm building a Visual Studio extension, which should add my tool button on a ToolBar or ToolStrip.
There are 2 cases:
first case, add my red button to the toolbar/toolstrip which was added by another extension (Visual Micro), see image 1.
second case, add my red button to the Properties toolbar/toolstrip of the Visual Studio UI, see image 2.
Image 1:
Image 2:
I tried to implement the second case, but without any positive results.
Here is the code:
...ANSWER
Answered 2021-Dec-16 at 17:09There aren't any toolbar or toolstrip HWNDs in WPF windows. What you are trying to do is not possible. If you need to add any visuals to Visual Studio's GUI, use the public API. This isn't just better, it's the only way to do this.

I just wanted to use simple math in my script, but as soon as I start it, "Percent Red" gets infinity. Ive researched and I found out that it can be caused by a DivisionByZero, but I don't know what I did wrong, I have tried everything I could.
...ANSWER
Answered 2021-Dec-07 at 17:46I can just guess but from your results and ho you use them I'd assume that all of these RedClick
, BlueClick
, Percent
, AllClicks
are of type int
.
So, what you get is an Integer division! For int
values the /
is without decimals!
=> as long as AllClicks < 100
you get

QUESTION
I am building a VB.NET Win Forms app that is reading the serial output of an Arduino and I want the VB.Net app to do something based on what it reads from the Arduino. The problem I am encountering is that even though I can read from the Arduino I can't seem to write it into an if statement.
The Arduino is a simple 3 button schematic. A red, yellow, and green button attached to digital pins 2,3, and 4. When one button is pressed the Arduino outputs the text "Red Button On", "Yellow Button On", or "Green Button On" depending on which button is pressed.
In the VB.Net app I have a label named lblHintRequest. I can load the arduino serial output onto this label. However, once I load the arduino serial output onto this label I can't seem to do anything with it. What I need is an if statement that will read which button is pressed and then do something depending on the button pressed. I have also tried adding a timer that ticks ever 500 ms that would read the label and this still did not work. The vb.net app just keeps skipping over the if statement.
The last thing I can think of trying is to use a textbox instead of a label and maybe that would help? But I really want this to be a label.

Answered 2021-Jun-09 at 17:54Since you have the value returned by the Arduino in a variable, you can use it in your If
