I know that if you declare a function as a data type you can return a value, but my question is, is there a way to get back other values from a function without declaring it as an arraylist? For example, if you made a GetValues function, is there a way to get a value by using something like GetValues.A or GetValuesB?

In this case the GetPosition control is returning a robot axis position. It looks to me like the values coming back from the function is not getting converted to object type properly.
I have a search page with a couple of pulldowns. Dependig on the values of them I show a grid matching the searched criteria, basically a table with links the user can navigate to. My problem comes when the user wants to navigate back. At the moment I have a "Back" button which simply redirects the user to the initial search page. I think it would be a good improvement to have the values of the pulldowns filled in with the values the user selected, this way when he presses the "Back" button he would not have to restart the whole search process again.

Can anyone give me the best method of passing back a value from a Thread?I have some procedures that I have set up as threads that I'm starting at the same time.My main function then waits until the threads are done and I'm needing to get back some values that the threads have created.Is there a better way to get these values back rather than just having them set a global variable with the returned value? Also, what is the proper way to wait for a thread to to be completed?I've just got a loop waiting for the Thread. Thread State property to not be in the Running state.So if there is a more proper way to wait for the thread to end I would be interested in knowing it.
View 7 RepliesI have a "result" which is DataTable and I like to get the x distinct values(City) and convert it back to DataTable how do I do this the code below gives me an error
Dim query = (From x In results.AsEnumerable()
Select (x.Field(Of String)("City"))).Distinct().CopyToDataTable()
so what I want is records of distinct cities I can get that but the problem I am having is converting it back to Datable.
Edited:I am using "where" in this statement and it does convert to Table(works fine) but not on "select"
Dim results = (From myRow In ds.Tables(1).AsEnumerable()
Where (myRow.Field(Of String)("xxxx") = xxxx)
Select myRow).Distinct().CopyToDataTable()
I am trying to return a javascript function using response.write in an aspx page. The problem is that the function i am returning has lots of quotes and they are conflicting with the repsonse.write syntax. Here is a sample code:
Response.Write(" If hello.StartsWith("H", StringComparison.InvariantCultureIgnoreCase) OrElse hello.StartsWith("W", System.StringComparison.InvariantCultureIgnoreCase) Then")
This is giving me a problem as the quotes inside are cutting off the response early. Is there a better way to do this?

View 2 RepliesI have an infratistics grid that when I click on a row, the activerow gets set, then I click a button that will open a terminal form and ssh to an IP address in one of the activerow cells. It's not a problem until I connect to another row afterwards and it resets the activerow causing both forms to refer back to the latest activerow which would only be correct for the latest form opened. The problem then is that the terminal form refers back to the activerow cells for various updates. From my main form where the grid is, I open a new frmWodTelnet form to connect to the IP like this: [Code]
I haven't actually tried this yet, can't until next week just trying to get a grasp on how best to proceed. Does this look like it might work out for what I need, to lock the form values back to the original row until the form is closed? Or is there a better option I should be looking at.

I am using MS Visual Studio 2205 Version 8.0.50727.42 and MS.Net Framework Version 2.0.50727 SP2 I created a form that requires the user to enter a date into the textbox.I then use the IsDate function to check if the entry is a valid date. IF Not IsDate(fieldname) then send message back to user on form, otherwise continue.If something like this is enterred - 06/090/10 - It passes the IsDate question and of course fails at the database level when inserting to a datetime field. Although there is a three character day, it still passes.

I have 3 variables. Lets call it "a", "b" and "c". These 3 variables can "independently" have 3 different values. Lets say: "1", "6" and "10". when you think of them as combination; there are (3^3) 27 combinations. I am told that it can be done through the recursive functions. However i am not a good developer to handle with that. Would u please help me?
- 3 variables and 3 different values are simplified. In fact; the numbers of variables and different values can vary.
- i know only the language, visual basic in .net; please don't answer in other coding languages.
additional note: i am going to put the these combinations in the string format into a collection.. for example "1;1;1", "1;6;1", "1;6;10".. and so on..
Is it possible to make a function that returns both a datatable AND a list(of custom class) at the same?In my GUI layer, the main form (the application is MDI) calls this function and it has to fill the datagrid on one of its child forms and it also has to fill lot of other child forms with various information that is calculated from my custom class properties.Both the datatable and the class properties are created from the same external database and that's why I don't want to have two separate functions.

View 8 RepliesI am working on a project I would like to use a function in a class I created to return multiple values in order to populate a listbox. I wanted to use a do until loop to achieve this. I will just post a simplified example of what I am doing :
Public Function Listboxfiller
Dim astring As String = "This is a string"
Dim Counter as integer = 0
Do until Counter = 5
return astring
Counter += 1
Loop
Then on the form I would do something like :
lstListbox.Items.Add(Myclass.Listboxfiller)
What happens right now is that the listbox only gets the first value, when I ran through in debug mode I found the loop only runs once, even though it should go multiple times.
I have two files. My form and a module with helper functions and the definition for a structure. For some reason, when I call finish_up, which should calculate how much freespace a disk has, the values just revert to their original bytes value. However, if I put a msgbox inside the function, the correct information is displayed. Just not once it goes back to the form.
Public Class Form1
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim Disks As New List(Of DiskData)
Search_Disks(Disks)
Finish_Up(Disks)
For Each x As DiskData In Disks
[Code] .....
The finish_up sub should go through each diskdata structure, find if it isready, calculate freespace and size down to their proper amounts and then just send it back. I don't understand where the problem is.
