Second function call won't work

[flann]

I'm trying to use functions, I'm still pretty new to this. I have two function calls going to two different functions. No matter which one I call first, only the first one will work, not the second. I've switched them around and its always which ever one I put first that works. Any thoughts?

 

            lblQualify.Text = CalADPSPayOffDate(CreditorNameArray, BalanceArray, MinMoArray, PctArray, PriorityArray, numRecs, accMargin, totalIncome)
           lblQualify.Text = Format(lblQualify.Text, "fixed")

           lblPlusQualify.Text = CalADPSPlusPayOffDate(CreditorNameArray, BalanceArray, MinMoArray, PctArray, PriorityArray, numRecs, curADPSPlusAccMargin, totalIncome)
           lblPlusQualify.Text = Format(lblPlusQualify.Text, "fixed")

Do you get any errors generated? If you step through the code in the debugger what happens?

When I debug I don't get any errors, and the first call has a value, the second call is 0. That is what happens no matter which one comes first, its always the first one to get the value and the second doesn't. I'm stumped :(

Try putting Option Strict On at the top of the source file and fix any errors it throws up, also could you post the code for the 2 functions themseleves?

It still didn't work, I would love to be able to post the function, but its a company calculation, and I signed a contract stating that I can't do that. Has this ever happen to you before?

I added a watch to the two calls, and this is what they both say.

 

Argument not specified for parameter 'CreditorName' of 'Public Funtion CalADPSPayOffDate......

 

What does this mean?

[PlausiblyDamp]

could you post the declaration for the two functions then? Also when you say the second call is 0 do you mean it returns 0? If so are the parameters you passing in correct?

Yes the second one always returns 0, and yes I'm passing it the correct parameters.

 

 

Function CalADPSPlusPayOffDate(ByVal CreditorName() As String, ByVal Balances() As Double, ByVal MinPymt() As Double, ByVal Pct() As Double, ByVal Priority() As Double, ByVal NumRecs As Integer, ByVal StartAccMargin As Double, ByVal curCombIncome As Double) As String

 

This is the same for both of them.

Does either function change any of the values in the arrays passed in? If so that is possibly a cause of the problem

That's it, it changed the values. Thank you

Now i'm trying to put the values of the arrays into different arrays for the second call. All the arrays are getting zero'd out after the function.

 

            Dim BalanceArrayPlus() As Double = BalanceArray
           Dim MinMoArrayPlus() As Double = MinMoArray
           Dim PctArrayPlus() As Double = PctArray
           Dim PriorityArrayPlus() As Double = PriorityArray

           lblQualify.Text = CalADPSPayOffDate(CreditorNameArray, BalanceArray, MinMoArray, PctArray, PriorityArray, numRecs, accMargin, totalIncome)
           lblQualify.Text = Format(lblQualify.Text, "fixed")

           lblPlusQualify.Text = CalADPSPlusPayOffDate(CreditorNameArray, BalanceArrayPlus, MinMoArrayPlus, PctArrayPlus, PriorityArrayPlus, numRecs, curADPSPlusAccMargin, totalIncome)
           lblPlusQualify.Text = Format(lblPlusQualify.Text, "fixed")

Arrays are reference types, the code

Dim BalanceArrayPlus() As Double = BalanceArray

simply creates another variable that points to the same array in memory. IIRC you will need to look at Array.Copy(...) to perform a deep copy of the array.
