Write Progress through Whole Script (instead of Timer or through per function)

Question

Hello Team,
Is it possible to use the write-progress to begin a the top of a script and run through each function of the script (instead of a timer or per function) and at the end of the script complete?
For example, here I use a timer:
for ($i =1;$i = le 100; $i++)
function sWriteLogInformation
out-file
-FilePath $strLog
-Input Object
-Append: $true
-Confirm:$false
-encoding "Unicode"
Write-Host -Object $strText
Get-Process $ProcessName -ErrorAction SilentlyContinue
If (-not $?)
strText = "Application is not running."
Write-Host $strText
Else
Stop-Process -processname $processName
write-Host "Application Closed"
Write Progress -Activity "Please wait..$strText" -status "$i% Complete" -percentComplete $i;
start-sleep milliseconds 50
But I would rather it go through each of the steps/function in the script and close when finished.
Any input appreciated.
Thanks!

Two suggestions:  
Move the function outside of the for loop, there's no reason to define the same function 100 times.  It may not be a problem with this script, but with a large data set it will affect performance.  And it's just plain bad practice.
Move the Write-Progress command to follow the initial for statement so it is displayed immediately instead of after processing the first item.
As jrv suggested, you can have multiple write-progress statements that provide more information for each step, perhaps like this:
function sWriteLogInformation ($strText) {
out-file
-FilePath $strLog
-Input $strText
-Append: $true
-Confirm:$false
-encoding "Unicode"
Write-Host -Object $strText
for ($i =1;$i = le 100; $i++) {
Write Progress -Activity "Please wait.." -status "Checking $ProcessName" -percentComplete $i
If (Get-Process $ProcessName -ErrorAction SilentlyContinue) {
Write Progress -Activity "Please wait.." -status "Stopping $ProcessName" -percentComplete $i
Stop-Process -processname $processName
sWriteLogInformation "$processName stopped at $(get-date)"
} Else {
sWriteLogInformation "$processName not running."
Write Progress -Activity "Please wait.." -status "Inserting artificial delay" -percentComplete $i
start-sleep milliseconds 50
Not sure where $ProcessName or $strLog are being defined.  I modified your script to clean it up a bit and remove some unnecessary code.
I hope this post has helped!
