Return An Array From A Function To The Original Sub?
Oct 14, 2009
I'm trying to call a function from a sub, and have it return an array to the original sub.
I currently have:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Call Registry_GetUsers()
End Sub
[code]....
Which works, but I want to loop through each of the items in users from within the original sub, not the function, as it currently does.So I need to return the array to the original sub, so I can then iterate through it from there.
Before adding rows to a table I am evaluating the SSN number. These will later be flagged for correction so I am setting a datatable column to true or false if it passed muster or not.
I wrote a function to check the number and make the determination plus pad it with zeros and hyphens where they should be. My problem is I want to return the results in an array. I am getting system.string[] as the return value.[code]...
I want to return an array from a function.dt is a DataTable that is global
HTML Dim dr As DataRow For x As Integer = 0 To adoc.GetUpperBound(0) dr = ds.Tables(0).NewRow()
[code].....
I'm definitely missing something here. I am trying to return an array forn the sql statement, chich I can reference as abom() in the original source.The ultuimate goal is to manually populate dt.
Public Function Foo() as String() Dim bar As String = {"bar1","bar2","bar3"}
Return bar End Function
My situation is similar to the code sample above where I'm returning a string array from a function.
What I would like to do is just return the string array without having to declare a variable first and then return the variable.Something like this, although this obviously doesn't work:
Return {"bar1","bar2","bar3"}
Is it possible to do this, I can't seem to find a method that works?
I have a class called Customer. It has some property like custID,custName..etc. Inside Customer class I have a function which returns an array of customer.
I wrote a function like this : Public Function InitLoadCustomerDetails() As Customer() sql = "SELECT* FROM tblCust" ds = classDC.queryHandler(sql, "InitCustomerDetails") Dim customerArray(classDC.maxrow - 1) As Customer Dim currentCustomer As New Customer [Code] .....
But it is not returning an array. Just a customer variable?? Public Function InitLoadCustomerDetails() As Customer() Return customerArray End Function Fix this to return an array of customer!!
Expected Results: A scalar result of the comparison between Array1 and Array2 such that when Array1>Array2 it is true. See expected array above. Actual Results: When Result(x) is true, all elements become Array1(x) and Array2(x) .What is wrong with the function?
I'm working on a program dealing with jagged arrays.Code is below.The FindPath() function works perfectly.It essentially randomly chooses an action from 3 possible choices.The goal of this function is to make it to position (3,3) from (0,0).Sometimes it makes it, sometimes it doesn't.It gives up after 2000 moves.
The PushButton() function is where I have the problem.I want to run the FindPath() function 2000 times, and return the resulting list of moves into intLists()(), my jagged array.I want to use
intRuns = 0 For intRuns = 0 To intLists.GetUpperBound(0) lstMoveList.Items.Add(intLists(intRuns).GetUpperBound(0)) 'here is where I get the problem.
this section of code to dump the number of attempts it took into a listbox on the main window.I do this at the bottom of the FindPath() function, but that is for testing purposes only.I eventually want to take the successful attempts and manipulate those, so eventually I get the minimum possible number of movements to get from the starting point of (0,0) to the ending point of (3,3).
Function PushButton() Dim intRuns As Integer Dim intLists(2000)() As Integer[code]...............
I have an array of people stored in a custom structure array... how can i copy this array to a temp array so that the temp array has all the same values as the original custom array?
I have a list of movie names in a list view. The user clicks a button and the posters and names are displayed instead. I want to be able to change it back to the list again. The problem I am facing is the size of the rows stay the same as the pictures when there not even there, the text alignment isnt fully to the left either. Is there a way to return the listview to its original state?
I've come unstuck on a certain point. I am trying to find a way to compare two lists and output only lines which are unique. In other words, remove both occurrences of duplicate lines.I'm relatively inexperienced with VB.NET, but this is how far I have managed to come;
Code: Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim LinksList1, LinksList2 As String LinksList1 = Replace(RichTextBox1.Text, "#vch", "") : LinksList2 = Replace(RichTextBox2.Text, "#vch", "")
[code]....
1) search the array to find duplicates and add them to a second array, then have a second pass to remove anything which matches the second array.
2) search the array for one duplicate and store it, then search the array again to remove the duplicates, and run that process until there are no more duplicates.
Then again, I could be going about this completely the wrong way. If that's the case, feel free to knock some sense into me.
Just so it's known, this question is mostly academic, even though I tried to use the concept in a real-world solution. I realize the example is contrived, but I believe the concept is valid.I want to write some fluent code like this:
[code]...
I realize that I can't force an anonymous type into a specific type (like implementing an interface or some other class), and I don't want the overhead of defining a specific class just to match my desired fluent name with the actual method name. So I was able to make the code work like this:
copy(my_first_file).to.Invoke(my_second_file)So there is no IntelliSense or type awareness there, and I have to include the Invoke in order to have the method run. How can I get more type safety and exclude the Invoke method, under these constraints: Anonymous Type returned from Method No additional classes or interfaces Preferably, I do not want to pass in another parameter to the copy() method that tells what type to return, unless copy becomes a generic method (but I think that means defining another class/interface, which I don't want to do)
Row3 ;W910 RF350022 ;Increase backlight by 100% ;(c) spring ;(p) spaceman +1000000 F5 000000 5555 44 555555 904938291 8676859 00
Row4 (Duplicate of Row3) ;W910 RF350022 ;Increase backlight by 100% ;(c) spring ;(p) spaceman +1000000 F5 000000 5555 44 555555 904938291 8676859 00
if label1 = RF350022 label2 = Increase label3 = spring label4 = 100%
only if it contains all of these words it should return the first instance (row3) then end or null the rest (row4).how can i get row 3 to show in message box now it has been found?
I want the Function to accept List(Of String), Array & String and similarly return List(Of String), Array & String respectively. The Function simply adds a string (month) to the input collection. I just want to use it for string, array and list with needing to think of conversions.
I have a vb6 program which shells and runs a Vb 2005 program, I would like to be able from that VB 2005 program run a function back in the original VB6 program which called it. Callback?

how return four value from a function. In general function will return single value but here i am going to return four different values. If possible please tell me how to store the function return values.
I've created my own version of HexToDec() to properly handle the negative flag. I saw other versions online that used "Not(value)" to do the Pos/Neg inversion, but that does not generate the proper value... No, it's not the most elegant my any means. But I couldn't find anything online that actually worked.
Long story short, I want to return NaN in the case that the function is passed a string that is not a valid hex string...
How do I do that? Everything I've tried generates a compiler error... (assign return value to double.nan, assign return value to non-numeric, etc)
Existing function is below:
Function HexToDec(ByVal hexStr As String, Optional ByVal signed As Boolean = False) As Long Dim lngFinal As Long
