Azure Internet of Things (IoT)

Putting together an IoT concept app using Azure IoTHub, Service Bus, Event Hubs, Streaming Analytics, and Power BI using my MSDN credits. Good stuff. Next I will hook it up to a mobile app for an end to end demo.

Azure Event Hub

Putting a ; at the end of an Azure Event Hub connection string causes an Invalid Token Error. Wow, frustrating.

Normalize range of values

Normalize range of values

double scaleMin = 0; //the normalized minimum desired
double scaleMax = this.ActualHeight; //the normalized maximum desired

double valueMax = data.Max();
double valueMin = data.Min();
double valueRange = valueMax - valueMin;
double scaleRange = scaleMax - scaleMin;

var normalized =
    data.Select(i =>
        ((scaleRange * (i - valueMin))
            / valueRange)
        + scaleMin).ToArray();

TAB pressed on WinForm

To determine if the TAB key was pressed on a WinForm, over ride the ProcessCmdKey event.

I created a custom control of NumericUpDown and added a check when lost focus if IsTabPressed

public bool IsTabPressed { get; set; }

protected override bool ProcessCmdKey(ref System.Windows.Forms.Message msg, Keys keyData)
{
    IsTabPressed = (keyData == Keys.Tab);
    return base.ProcessCmdKey(ref msg, keyData);
}
