VS 2008 : Re-index Variables To Non-negative Integer Values?

Oct 19, 2010

I have a program that calculates values of a function, say f, with respect to another variable, say L.I have an array of f(L), for L going from 0 to a given integer value, say t-1 in steps of a value i.I need to export the values of this function to an Excel spreadsheet in a given column, and to do this, I would like to re-index the function f, since i is much less than one, and so the following loop I use (see below) won't work:

For L = 0 To t - 1 Step i
Sheet.Cells(L, 1) = L
Sheet.Cells(L + 1, 2) = f(L)
Next L

The first code in the loop will essentially load the values of L itself, at which the function is defined and calculated, and the next line will load the values of the function at each value of L.Since the indexes of the row and columns in an excel spreadsheet only go in steps of 1, I need to convert the indexes of the function, or the indexes to which L is loaded, so that it would be scaled so that the first entry corresponds to L=0, but the next is L=i, but loaded into row number 2, etc.

Looking For .NET Math Method That Will Zero A Negative Integer?

Mar 24, 2010

Similar in concept to Math.Abs() - I'm looking for a function that when given a positive integer will return the same integer. If given a negative, will return zero.

So:
f(3) = 3
f(0) = 0
f(-3) = 0

Yes, this is simple enough to write on my own but I'm wondering if the .NET Math class already has this built in or if the same can be achieved by cleverly chaining a few Math.* calls?

Error : Index 0 Is Either Negative Or Above Rows Count

Jan 6, 2009

I have a button that is supposed to display a form:

Code:
Private Sub btnEditAssociate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnEditAssociate.Click
frmEditAssociate.ShowDialog()
End Sub

Code:An error occurred creating the form. The error is : index 0 is either negative or above rows count.There is a database call on the form load property of that form, so the problem could be with that, but the when I step into the showdialog() call it produces that error on the show dialog line, so I can never see what is going wrong.

VS 2008 Reset All Integer Values?

I am trying to reset all integer values to "0" with a reset button.I try not to use hardcoding by simply set them one by one. So my idea was checking all the variable's type and set them all to "0".

I tried to use this methode, from someone in this forum (sorry, I forgot the name but this is very helpful...) For Each ctrl As Control In Me.GroupBox4.Controls 'Check and see if this control is a TextBox
If Object.ReferenceEquals(ctrl.GetType(), GetType(Label)) Then 'Check and make sure this s the "TextBoxToExclude"
'CType(ctrl, CheckBox).Checked = False
CType(ctrl, Label).BackColor = InactiveColor

Next

But when I tried to find the code, I couldn't get it.So, if anyone knows how to do this,
