I don't understand why I cannot compare an array in VBA. I created an array that starts 0 1 2 3. I added a comparison due to subscript errors trying to compare 0 to 0 - 1 so it can only start comparisons at 1 and continue. Now I'm receiving a type Mismatch 13 and I can't figure out why the data type is different/not working. I'm guessing i in a for loop is not considered an int or something?
It fails at CoordinatesArray(i) = CoordinatesArray(i-1)
Code:
For i = 0 To NumLines - 1
coordx1 = (vLines(12 * i + 6))
coordy1 = (vLines(12 * i + 7))
coordz1 = (vLines(12 * i + 8))
CoordinatesArray(i) = Array(coordx1, coordy1, coordz1)
If i > 0 Then
If CoordinatesArray(i) = CoordinatesArray(i - 1) Then
coordx1 = (vLines(7))
You will need to compare each value in the jagged array separately:
For i = 0 To NumLines - 1
coordx1 = (vLines(12 * i + 6))
coordy1 = (vLines(12 * i + 7))
coordz1 = (vLines(12 * i + 8))
CoordinatesArray(i) = Array(coordx1, coordy1, coordz1)
If i > 0 Then
If CoordinatesArray(i)(1) = CoordinatesArray(i - 1)(1) And _
CoordinatesArray(i)(2) = CoordinatesArray(i - 1)(2) And _
CoordinatesArray(i)(3) = CoordinatesArray(i - 1)(3) Then
coordx1 = (vLines(7))

Can anyone please help me with this problem? Can't find solution, not even on Visual Basic help page! It shows me error on this 2 code lines:
Me.DataGridView(j + 1, 1) = Niz1(j)
Me.DataGridView(j + 1, 2) = Niz2(j)
It says : Value of type 'Single' cannot be converted to 'System.Windows.Forms.DataGridViewCell'
Instead of trying to assign a Single value to a DataGridViewCell object, you should assign it to the .Value property of the object ..
Me.DataGridView(j + 1, 1).Value = Niz1(j)
I have written the following code in VBA and I get a Type Mismatch error in the conditions of the ;SUMPRODUCT;.
For Day = 1 To DaysTill
For m = 0 To Rot
For n = 0 To StepsNumber
RArray((Day - 1) * (Rot + 1) + m, n) = Application.WorksheetFunction.SumProduct(--(Range("HT12:HT1048576") <= RotArray((Day - 1) * (Rot + 1) + m)), --(Range("HS12:HS1048576")) = Day, Range("HT12:HT1048576"), Range("HV12:HV1048576").Offset(, n)) * PriceStepArray(n)

Does anyone know how to fix this?
I have issue with an Excel worksheet that contains the formula:
=Spline($D$9:$D$34,$J$9:$J$34,$D43)
Sheet works fine until I open this sheet on network drive and save it on local drive. Then this formula throws #NAME? error. Strange is, that error is gone when I click on line with formula to edit it and press enter (nothing changes in formula).
Have someone met similar issue?
I just found another information. Formula spline is defined in VBA module, not internal in Excel. It looks like. But issue is still here.

Try to add:
Application.Volatile
to your VBA code. Add this just below the Function statement to force a renewed calculation as soon as anything changes.
I have a function that only call the spline function when something happens..in this case when a division is less than zero..the inputs for the function is the same that for the spline function(called CUBIC), the spline was tested and works well when I call it direct! someone can help me?...follows a party of the code

The function returns a zero value when I call the cubic function. The inputs are a cell with a value with a value equivalent a day and two arrays(DUONOFF and ONOFF) equivalent a days and rates, I call the function like:

In VBA, I can easily pull in an sheet\range into an array, manipulate, then pass back to the sheet\range. I'm having trouble doing this in VB.Net though.
Here's my code.
Rng = .Range("a4", .Cells(.UsedRange.Rows.Count, .UsedRange.Columns.Count))
Dim SheetArray(,) As Object = DirectCast(Rng.Value(Excel.XlRangeValueDataType.xlRangeValueDefault), Object(,))
For X As Integer = 0 To SheetArray.GetUpperBound(0)
If IsNothing(SheetArray(X, 0)) Then Exit For
SheetArray(X, 6) = SheetArray(X, 3)
SheetArray(X, 7) = CDbl(SheetArray(X, 3).ToString) - CDbl(SheetArray(X, 1).ToString) - _
CDbl(SheetArray(X, 7).ToString)
For Y As Integer = 0 To 3
SheetArray(X, Y * 2 + 1) = Math.Round(CDbl(SheetArray(X, Y * 2 + 1).ToString), 3)
Next
If Math.Abs(CDbl(SheetArray(X, 7).ToString)) > 0.1 Then _
.Range(.Cells(X + 1, 1), .Cells(X + 1, 8)).Font.Color = -16776961
Next
I'm getting an error on the first If IsNothing(SheetArray(X, 0)) Then Exit For
line. It is telling me index is out of bounds of the array. Any idea why? The SheetArray object contains the data, but I just am not sure how to get to it.
In the For you have to loop from 0 to Count - 1:
For X As Integer = 0 To SheetArray.GetUpperBound(0) - 1
'...
Next
That will fix your problem.
