VB.NET – Form design
Figure 10 shows the form in the VB.NET form designer. Each of the items has the name given by VB.NET when I placed it. (I added the pink labels to the screen shot manually)
- Label1 represents the heater. You can make it large and change its font to white and large, like I have, but that’s not essential
- Label2 shows the state number
- Label3 contains “°C”
- Label4 shows the timer
- NumericUpDown1 sets the tank temperature
- OvalShape1 is the alarm indicator
- Button1 is the alarm reset button
In addition to the above, you also need to generate a Timer control. Select Timer from the VB Toolbox, and click onto the form background. Timer1 should appear in a grey band at the bottom of the form designer.
