cant link a textbox value to a progressbar value, need loop code

I have an app that connects to a com port and displays the temperature through a label control and a textbox control,  I also have a  Mabry indicator control that is coded to show the value of this textbox ( very similar to a progressbar). Currently,  the only  way  to see the gauge work  is  a button I made called "poll" which executes the code that syncs the text1 value with the gauge...If it is pressed before data is in the text1 box, an error is generated.  What I want, is after the com port is connected, for the poll gauge code to run and loop to update the gauge every so often so that it is a visual represention of the number value in the textbox.  So what I need is the poll button to be "pressed automatically"  and for it to loop endlessly  about  every 15-30  seconds,  BUT ONLY  after  com1 is connected and there is a value in the textbox.   Could someone  show me the  code for this?  I think  it  is  basically  a loop  with a few conditions. But  I have tried  a few things  and am  getting  nowhere.

It seems like you could use the "Text_change" event from the text box control. When the text box gets updated from elsewhere the event will fire and you can execute the code that links the text box to your Mabry control.
If for some reason this doesn't work you can use the timer control to sync the textbox to the Mabry control. The timer control fires an event whenever it reaches a preset interval. Use the event to sync your controls and then reset the timer.

I briefly tried that with the text_change event  but had  no  luck.. I will try again though....would  the  code  be a goto  or call a function or sub....I tried text1.text = MabryCntrl.Value = ....under  the text_change event but that didnt  do it....can  you elaborate  on the timer  technique you meantioned?  As  I dont know much about  how to sync things.

If you want the Mabry control to display the value of the text box use "mabrycntrl.value = val(text1.text)".
You should try using the text_change event first. It's a lot cleaner than putting in a timer control. If you use the timer control you will have to worry about setting the interval to something that is fast enough to get the response you want without wasting a lot of cpu checking for changes that haven't occurred.
