Expected Results: A scalar result of the comparison between Array1 and Array2 such that when Array1>Array2 it is true. See expected array above.

Passing An Array Of Integer To An Array Of Object In A Function
Mar 4, 2012I am creating a dll with all the functions and subroutines that I use all the time and I decided to create a function that I can pass different types of array to so the function obviously (or not) would have an array of type object. Now I no you can pass any type into an object type but when I pass an integer array into an object array I get an error.
value of type '1-dimensional array of integer' cannot be converted to '1-dimensional array of object' because 'integer' is not a reference type.

Passing A Constant Array To A Function?
Jul 23, 2009pass an array to a function, like the code below shows
Private Sub SomeFunction(ByVal PassedArray() As String)
For i As Integer = 0 To PassedArray.Count - 1
Debug.WriteLine(PassedArray(i))

But is there a way to pass a constant array to a function in VB .Net, for instance in PHP you could write
function SomeFunction($array)
{
for($i=0;$i<count($array);$i++)

So to reiterate: Is there any way to pass a constant array directly to a function in VB .Net? Is there any benefit in doing so? I imagine a few bytes of memory could be spared.

View 2 RepliesPassing The Result Of An Array-Valued Function From A Fortran95?
May 25, 2011I am interested in developing a multi-language program that will have a main .NET GUI but will perform calculations by calling procedures from a Fortran95 dynamic link library file. Right now I am just playing around with a very simple project in order to get the interoperability between the .NET framework and a Fortran95 (*.dll) file working correctly. So far, I've been able to pass the Fortran95 (*.dll) file an array from VB, sum all the elements of the array using an intrinsic Fortran function, and pass the scalar result back to the .NET framework with no problem. However, if I try passing Fortran the exact same array, construct the transpose of that array using another intrinsic Fortran function, and try passing the transposed array back to the .NET framework I keep throwing an exception. I am not a programming wiz, but it appears that when Fortran stores an array in memory, the .NET framework doesn't know how to read that. I am looking for some guidance on how to pass an array from the Fortran95 (*.dll) file back to the .NET framework.
View 9 RepliesVS 2008 Copy One Dimensional Array Into Two Dimensional Array?
Feb 17, 2010I have a string containing many lines. Each line has many values separated by commas. Basically it's in CSV format. The number of lines is variable but the number of columns is always 7.
I can get each line into a one dimensional array using Split(Var, Chr(10)).
I'd like to make it a two dimensional array where the second dimension contains each comma separated value.
I've got
Dim VarArray1() As String = Split(VarText, Chr(10))
Dim VaryArray2(0 To VarArray1.Length - 1, 0 To 6) As String
Is there a quick way to get the contents of VarArray1 into VarArray2. I know I can do the following.
For Counter = 0 to VarArray1.Length - 1
Dim line as string = VarArray1(Counter)
Dim Values() as string = Split(line, ",")
For Counter2 = 0 to 6
VarArray2(Counter,Counter2) = Values(Counter2)
Next Counter2
Next Counter
But is there a quicker way to do it that doesn't require passing through each element of VarArray1 and then passing through each element of Values.
The eventual goal in all of this will be to find the highest value in the 3rd column (the arrays are strings at this point because not all columns are numeric). To do that once I get the values into VarArray2 I suspect I have to pass through each element VarArray2, i.e. VarArray2(Counter,2). Unless I can copy the whole third column into a SortedList?

One Dimensional Array Application
Mar 7, 2009i'm extremely confused. my professor gave us this as the FIRST problem to do in this intro to VB class...on page 380 of our text. it is due today and i have been up all night trying to figure out where to even start. i'm so frustrated. could someone please help me and steer me in the right direction? use a one dimensional array to solve the following problem: a company pays its salespeople on a commission basis. the sales people receive $200/week, plus 9% of their gross sales for that week. for example, a salesperson who grosses $5,000 in sales in a week receives $200 plus 9% of $5,000, a total of $650. write an application (using an array of counters) that determines how many of the salespeople earned salaries in each of the following ranges (assuming that each salesperson's salary is truncated to an integer amount): $200-299, $300-399, $400-499, $500-599, $600-699, $700-799, $800-899, $900-999 and over $999.
Allow the user to eanter the sales for each employee in a TextBox. The user clicks the Calculate Button to calculate the person's salary. when the user is done entering this information, clicking the Show Totals Button displays how many of the salespeople earned salaries in each of the above ranges.
