Figuring out Timer Interval for Progress Bar
I'm having a really hard time wrapping my brain around this one.
I have a button, a timer, and a progress bar.
Dim L As Label
TotalTime = "0" 'set the variable that tracks the total required time to 0
For i = 1 To 5
Set L = Form1("Liq" & i & "_Amount")
TotalTime = Val(TotalTime) + Val(L) 'for each value, add it to the total time required
Next
pbtimer.Interval = Val(TotalTime) 'PROBLEM LINE - this is where I think the error lies
pbtimer.Enabled = True
Then the timer code is
Private Sub pbtimer_Timer()
If ProgressBar1.Value = 100 Then
Exit Sub
Else
ProgressBar1.Value = ProgressBar1.Value + Val(TotalTime) 'add one percent to the progress bar
End If
So, let's say I need .99 total seconds to complete the task at hand. How do I set the timer interval to fire off every one hundreth of the required time? Times 1000 for the timer's interval? How does the percent (1/100) of what I want to do and the 1/1000 = one second property of the timer both interact? See my confusion? (...maybe this is more a math question than a VB question?)
Thanks!

What is it you're trying to do?
I agree with JR2003. Please explain a little more about how your program should work.
Can't quite make sense of the code you posted...

TotalTime is the total amount of time needed to reach 100% on the progress bar.
I cannot figure out how to set the progressbar.max property or the pbtimer.interval properties to cause the progress bar to take 'totaltime' amount of time to reach 100%
I am confused over the interplay between having to specify the "amount" to add to the progress bar per timer cycle in a Percent (out of 100) and the interval of the timer (where 1 second = 1000).
I hope that clears some up, let me know if you need more info!

Couldn't you just set the ProgressBar's .Max property to 1000 to avoid confusion? :-)
I am curious, what does this line do?
Set L = Form1("Liq" & i & "_Amount")

That line enables me to loop through my fields, they are named Liq1, Liq2, Liq3, and so on. L holds the name of that field so that the value can be pulled and added to "TotalTime." The fields as a whole add up to the sum of the amount of time the progress bar needs to be going from 0% to 100%.
I tried setting the progressbar max to 1000, it still escapes me how these all work together. Could you post example code of how this might work, or a description?

What are the values in Liq1_Amount thru Liq2_Amount measured in? Milliseconds? Seconds?
What is their format? Whole numbers? Fractions?

You can set the .Max value to the expected maximum value, and then at each update, possible timer-dependent, set the Value to the current value of whatever is being measured.
