I've got one function with a paramarray, and I want to pass the same paramarray to a second function. I do not control the second function, and so cannot modify it.
Public Sub Main()
Foo(1,2,3,4,5)
End Sub
Public Sub Foo(ParamArray Byval arg as Integer)

I have a Class Library that is exposed to COM like this:

[Code]....
Compile error:
Function or interface marked as restricted, or the function uses an Automation type not suppport in Visual Basic.
What do I need to do to properly expose this Method so I can use it like this?:
SomeClass.SomeMethod 1, 2, 3

A former co-worker wrote a class in C# that was to be used as an attribute. I'm having to convert his work to VB (yeah, it's pointless and way more work than necessary, but management thinks it's a good idea). Unfortunately I'm having an issue because one of the main properties of the class is an ArrayList which is set with a ParamArray in the constructor. The class looks like this (note I've tried to abstract out the problem, so this is a simplified version of the class only)
<AttributeUsage(AttributeTargets.Field Or AttributeTargets.[Property])> _
Public Class LabelAttribute
Inherits Attribute
Public Sub New()
[CODE]........
In the first one, there is just the single label being added. No Problem. In the second one there are 2 different labels being added. Again, no problem. The third one, however, is a problem because it's assuming that the "Description", which is supposed to be the description is instead being interpreted as another label.
This wasn't a problem in C# because it could be set as follows:
[CODE].................
Of course this doesn't work in VB because optional parameters aren't referred to by name as they are in C#. As a stopgap I've changed the constructor to allow only a single label like this
CODE]..................
But that undermines some of what this class is meant to do. Does anyone know how, or even if I can get the same basic functionality to work in VB?
Think there must be a way to make the existing design work. Imagine this class was built into a library that I could not modify. Would I be forever forbidden from setting Description because of this design?
I have an application that reads data values (numeric) from a data file. Due to a change in data requirements, I need to put these into a paramArray so I can calculate the MEDIAN of the series of numbers. I have seen some of the MSDN examples and they are all good except they load the paramArray with ArrayName(#, #, #, #, #). That's OK for a simple example, but how do I load a paramArray while reading numeric data from an ASCII input file? The number (Ubound) of samples is usually 153 but can vary considerably.
I think I can work out the rest of the MEDIAN calculation from the MSDN example code.
I'm building a class, and i let the user select several options to show or hide some features in another form.In my class i declared an enum with 5 values, and in one of my class constructors i declare an paramarray of the type of the enum.Now i want that when i declare a new object of this type, when the user put the "(" char, a popup/tooltip/intelisense (don't know what to call it), show all the options available. Like in the classes that allready exist in the framework...
View 7 RepliesSounds simple enough, but its not working. In this example, I want to set the values of 3 fields to equal a 4th. I could do something like this..[code]...
Values in the param array did not get updated in the return! I was expecting to have all of the final values now be "1", like they are in the Function.
Is there any way to get an update-able ParamArray collection like this? ParamArray must be declared ByVal, but with a reference type like String, shouldn't that only make a copy of the pointer and allow me to change the underlying value?
I have two tables:
table1
case_no flow result
tc_1 001 pass
tc_1 002 pass
tc_1 003 pass
tc_2 001 pass
tc_2 002 fail
tc_2 003 pass
table2"
case_no result
tc_1 pass
tc_2 fail
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..
This code was working consistently, but now...This code works on the first pass.Then second pass it just hangs on Code:Dim tcpClient As TcpClient = tcpListener.AcceptTcpClient() for about 2 minutesThen the code will fork for another pass, then fail.....

Just 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

I'm sure it's probably a very elementary question, but every explanation I've found seems to be incomplete.
I am looking for some input. I am helping with a web application that is fairly large. We have some logic factored out into classes, not a true business logic layer (yet ). The classes are setup to pull values directly from the QueryString or Session variables and I'm not sure that that mehtod is proper or even a
The reason I would like some input is, there may be a chance to rewrite or at least refactor the code.

Im a student doing an assignment, how do i pass the value from a sub procedure to a function procedure....i want to pass the value from decSubtotal to a function procedure named CalculateDiscount; check out my code--
[Code]...
But in my application i need to pass the ID of my Client (company) to fecth it's businessName. So first i've written a storedprocedure to return it's ClientID searched by BusinessName, then i pass the ClientID to fetch all the other details of the client such has his contatcs...etc....
Therefore currently i use two stored procedures to one i pass the businessName then i will return it;s ClientID then to the other i pass the ClientID then it will return everything about the client (beucase client was indexed on clientID)
Is it possible to write only one stored procedure to perform the two operations..

ok to start i know very little about VB6 but i am very good in true basic lol (stupid school teaching the wrong language -_-) anyway im just asking you to make the answer as clear as possible because i don't know very much. heres the problem . ok in the above example i have a button that (for my example) can be used to build a house (lol) i then have a variable in the button sub called money which will have 150 subtracted from it when the button is clicked my problem is it say variable not defined when using this button ... i have declared the variable in a module and in form load along with my other 50 or so variables. my question is how do i pass the variable into this sub and then send the new value back into form load so it can be sent into another sub for more calculations.

I have the following sub which works for the type "Button". I would like to make it general by having a parameter that is assigned a type rather than "Button" being hard wired. Can this be done? How do you pass a type? I tried the parameter "ByVal t as Type" but the compiler complained when I used t as a type and I also tried inserting (Of T)but the compiler complained about CType(control,T).
how add type as an input to this sub?
Public Shared Sub Example(ctrl As Control, items As ToolStripItemCollection)
For Each control As Control In ctrl.Controls
If TypeOf control Is Button Then
Dim butt As Button = CType(control, Button)
determine which component had been clicked?
I want to know what the best practice is for passing values (sometimes multiple values) between two asp.net pages
In the past I have used query strings to pass a value in asp like this:
href='<%# Eval("TestID","../Net/TestPage.aspx?TestID={0}") %>'><%#Eval("Title")%> </a>
I assume you can do this in the code behind but I do not know the best way.
I also assume it is possible to pass more than one value.
