Key board control

is their a way to press a push button or a basic button by using a key on the keyboard?

In the Text property of a button, insert an "&" before the keyboard letter you want to use. For example "Start &Motor". When you run the program, you can use Alt-M to click that button.

Does not seem to work.... Lets say in the text property I say ''&S'' then I should be able to type Alt S and should be working?

Yes. Try this:

- Add a BasicButton to the form
- Change the Text property to "&BasicButton1"
- Double click the button to get back to the code
- Enter this code:

 MsgBox("Button clicked!")

- Run the application and press Alt-B on the keyboard

I just thought about it and this will probably not work when controlling the PLC because the Alt-B action clicks the button, but the PLC writing is activated by Mouse Down and Mouse Up events.

Another option that may work is to Tab through the controls to get the button highlighted that you want to click , then press Enter.

Or you could write to the PLC via code in the Click event handler. In the example above, instead of using the MsgBox, you would use something like this:

EthernetIPforCLXCom1.Write("MyButtonTag","1")

I will try option 3 but in my case im using comdf1 will that still work?

Oh and please show me where in the code I must make these changes im am a noob at code

- Add a BasicButton to the form
- Change the Text property to "&BasicButton1"
- Double click the button to get back to the code
- Enter this code:

 EthernetIPforCLXCom1.Write("MyButtonTag","1")

- Run the application and press Alt-B on the keyboard

Keep in mind this will only set your PLC bit to true. You will need another mechanism to clear the bit, such as logic in the PLC

Show a screen shot of your MainForm so I can see the exact name of your driver.
