Pass Parameters To A Subroutine From A WPF Button?
Jul 26, 2010I have a VB.net WPF application that creates a list from a databind. For each row in the databind, it generates a textblock that displays the information from different fields in the databind. It also generates a button which I would like to run a subroutine when clicked.
When I click the button, I want it to be able to get the information from the databind on the column the button is clicked, and to pass it to the subroutine so the code-behind can use that information.

How To Pass Values From List Inside Of Class
May 5, 2011I am having a hard time trying to pass the values from a list inside of a class. I am trying to display multiple lines of values from a list inside of a class. My "client" class stores multiple lines of values into a list(of class transaction), with the number value (num) counting each transaction that it adds to the list.
Ex:
Public Class Client
Private m_tranlist As New List(Of transaction)
If CInt(tid) = m_ID Then 'create client tran, add to list
nextTran = New transaction(m_ID, tcode, tdate, ttype, tshares, tprice, value, num)
m_tranlist.Add(nextTran)
num += 1
End If
Now I am trying to display each line that is stored in the list in a label, and I am having major trouble. How do I call the list in my main form in order to display all of the values?

.net - ByRef Underlined With "Expression Expected" Error When Trying To Pass In A Object Of Type List(Of ClsFooDetail)?
Mar 3, 2010I work with C# 99% of the time. However, I'm having to update some legacy VB.Net code and encountering an issue with VB.Net code syntax. The error that I get is "ByRef" is underlined and "Expected Expression" tag shows up when you hover over "ByRef". The "FooDetail.Load" function is written in C# and expects a List object passed as reference. Don't have any trouble using the same function in other C# classes. Can someone indicate what is wrong with below VB.Net code.
Dim FooDetail As New clsFooDetail()
FooDetail.FooID = FooID
Dim lstFooDetail As New List(Of clsFooDetail)
FooDetail.Load(ConnectionString, "Stored Procedure", ByRef lstFooDetail as System.Collection.List(Of(clsFooDetail))

Table2 should be updates from table based on the results... If all results is PASS then the table2 should be updated as pass... if any result is FAIL then the entire case_no should be updates a s fail..

Pass Data To Dialog - Manipulate And Pass Back?
Jan 15, 2010Just started VB programming this week and have found a wealth of information about what I'm trying to do. Problem is, some of it is more complete than others.Here's what I'm trying to do:In Form1 (my main form), I want to instantiate a class that contains a couple of properties (speed setpoint and position setpoint). When I click a button, I want to pass this data to Form2 and populate two textboxes on Form2 with the properties of this object. I want to manipulate the property values on Form2 and click an OK button which closes the dialog and returns the manipulated data, updating the property values of the object. Here's the algorithm I'm following:1) On Form1, instantiate the class2) On Form1's "Pass Data" button click event handler, instantiate a Form2 object and invoke the ShowDialog method, passing the object as a parameter.
3) On Form2, overload the ShowDialog method to accept the object as a parameter and modify the method so that it returns the manipulated class data.4) On Form2, in the ShowDialog method, populate the textboxes with the class data that was passed in.Here's where I get stuck. If I press the OK button on Form2 (DialogResult.OK), it returns me to Form1, but what hook do I have in Form1 to receive the manipulated class data that the ShowDialog method is returning?Here's an example of what I'm thinking about:
Code:
Public Class Form1
Dim clsController1 As New MotionController
[code].....
I'm sure it's probably a very elementary question, but every explanation I've found seems to be incomplete.
Where Has The Subroutine Gone
May 9, 2010I am trying to get the hang of this stupid VB.net, but it won't even let me create a subroutine or function, it use to be in the tools menu in VB6. I have spent £50 on 2 books that rabbit on about objects, property's classes etc: but tell me nothing of what I want/need to know, what a waste of money.

May 1, 2010I have a form that is bound to a table of data. I have a typical binding navigator. When I go to a different record such as next, previous, first or last I need a subroutine named "LayoutAdjust()" to execute "after" the new next record data is loaded on form. I tried calling the subroutine in the "BindingNavigatorMoveNextItem_Click" action but it executed the procedure before the next record data was loaded
View 1 RepliesArray Passing To Subroutine In VB
Feb 7, 2010I have an old program written in VB6. I upgraded the program with VB 2008. The updated program works fine except when the program tries to transfer an array to another subroutine. The old VB6 program sends arr(0) as an argument to the subroutine, the address of arr(0) is passed to the subroutine. The array arr() address is the first of a block of consequent addresses one by one, arr(1), arr(2), etc.
Now when running VBnet, the address of arr(0) is not the first of all consequent arr(1), arr(2), etc. It is an isolated number, just like if arr(0) were a variable instead of an array. The addresses of arr(1), arr(2), etc do not exist in the subroutine. [Code]
The variable of y1 passes to the subroutine oK, whilst arr(0) passes also like y1 into an isolated address. So VBnet interprets arr(0) like a variable rather than the first value of a long list. I haven't been able to find out why the above sample does not work. I got stuck in my programming effort, as I cannot proceed to to further development. how the code should be modified to enable the whole array information passing through the subroutine.
