View 5 RepliesOOP - Declare Two Datatables And Fill Them Both From A Datatable Returned By A Function In Class
Sep 27, 2010When I declare two datatables and fill them both from a datatable returned by a function in class, that when i filter the one it seems to filter the other aswell?
For example:
I declare the datatable and initiate my class:
Dim DatatableOne As New Datatable
Dim DatatableTwo As New Datatable
Dim MyClass As New MyClass
I then call the function that returns a datatable and apply it to datatable1 and 2 Then fill two DataGrids with the table:
DatatableOne = MyClass.GetTable()
DatatableTwo = MyClass.GetTable()
DatatableOne.DefaultView.RowFilter = "Name = 'Tom'"
[CODE]...
For some reason i don't understand but both grids end up with the filtered data?
VS 2008 Too Many Arguments To 'Public Overridable Overloads Function Fill(dataTable As TetrisDataSet.tblTransactionDataTable) As Integer
May 14, 2009I'm following this tutorial: [URL]..except I'm connecting to my own data source - a MS Access database.This is the query I have setup with the dataset:
SELECT Terminal_ID, SUM(Transaction_Quantity) AS Total
FROM tblTransaction
WHERE TransactionType_ID=3 and Transaction_DateTime>[@fromdate]
GROUP BY Terminal_ID
The debug fails immediately because it needs the extra parameter so I change the code from:
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'TODO: This line of code loads data into the 'tetrisDataSet.tblTransaction' table. You can move, or remove it, as needed.
Me.tblTransactionTableAdapter.Fill(Me.tetrisDataSet.tblTransaction)
[code].....
The error I get on build is:Too many arguments to 'Public Overridable Overloads Function Fill(dataTable As tetrisDataSet.tblTransactionDataTable) As Integer
...I gave it the extra parameter, so what gives? Something special I need to do as it's a datetime field?

Call A Function / String That It Uses Will Be Given To Function To Initiate A Download?
Aug 21, 2009Some programs implement command parameters, Like my favourite computer game - Crysis - has them and windows media player has them.But how could i implement them in VB.NET..I want to have a component of my program built as a seperate exe - so it can be an Optional component.But of course the seperate exe, on load, needs data passing to it.So i need something like Process.start("Componentname.exe", "/StartDL <Suchandsuchastring>)/StartDL will need to call a function, and the string that it uses will be given to the function to initiate a download?

Feb 4, 2010The following output produces a string with no closing xml tag. m_rFlight.Layout = m_rFlight.Layout + "<G3Grid:Spots>" + Me.gvwSpots.LayoutToString() + "</G3Grid:Spots>"
This following code works correctly

m_rFlight.Layout = m_rFlight.Layout + "</G3Grid:Spots>" 'add closing tag
What's going on here, what's the reason the first example isnt working and the second is?
The gvwSpots.LayoutToString() function returns a string.

View 7 RepliesCode An "auto-fill" Function For Combo Boxes?
Jul 22, 2010I have combo boxes for user choices on the form. One combo box for name, one for phone number and one for email. I first created that to allow user to make select in each combo box. As more "user friendly" interface, I I would like to associate the selection made on cmbBxReqstrName with corresponding phone number and email and cause the phone number and email combo box to "auto fill" in their respective combo boxes based on the selection in the cmbBxReqstrName. It was suggested to me that a two dimesional array might be an option. I read up on arrays but don't quite comprehend the coding part to access the data in the array and fill that to the combo box or I guess use the index from array to index the combo box list.

VS 2010 : Fill A "gap" After Removing A KVP In A Sequential String Key Based Dictionary?
Jan 2, 2012I need to remove an instance in a class for which I also created a dictionary with a string key type. Like this...:
vb
'Declare dictionary
Public PersonsList As New Dictionary(Of String, Person)
'At the bottom of frmMain.vb
[code]....
As you see, I end having 120 instances of the class Person, each assigned with a string key consisting in "student1" to "student120".
At other parts of the program I repeatedly refer to PersonsList("student" & n) to set values at those class entries, mainly with a For n ... Next block.
Now... I need a routine to remove one of those instances for good, including its entry at the dictionary, so my first bet is this...:
vb
Public Sub ExpellStudent(ByVal student_index As Integer)
PersonsList.Remove("student" & selected_student_index)
students_count -= 1
End Sub
I assume this is good enough to remove the KVP at the dictionary AND the class instance proper... right?Well, even if that is ok, I foresee one problem... Let's say I removed "student46". Next time I run a For n = 1 to students_count I would bet that I'll receive an exception due to having a gap at "student46" KVP... and that without saying that students_count will be 119, so it will never reach "student120".In short, I need a way to reassign the KVP of the now 119 Person entries, so they're consecutive again (I don't care about them changing their string key values), so I still could use my For n = 1 to students_count ... Next blocks without problems... but I cannot figure out how.

C# - Random String Function ?
Jul 31, 2011I've made a function in C# to create a random string, but I wanted to convert it to VB.NET, unfortunately my knowledge of Visual Basic is much less than my knowledge of C#.
Here is my VB.NET function:
CODE:
As you will see, its not much different from my C# version, except that since VB can take an optional parameter, I allow the user to select what characters to use in the string, or just use the default ones.
Here's the C# version of my function:
CODE:
Again, there's not much different, but the part I'm really struggling on is the conversion between what is the 12th line of VB code, and the 13th line of C# code. I didn't really know how to convert it to VB.NET (as I said, my knowledge of it is very limited), so I used an online converter. The result of the online converter runs with no errors, however when I try to call the function, no string appears.
In short, this C# code works fine:
CODE:
However, this VB.NET code doesn't work:
CODE:
How could I fix my VB.NET code?
