Gets A String (mysub(string)), But AddressOf Doesn't Accept A Parameter Inside The Routine?
Aug 18, 2011
I have buttons generated through code (dynamically). I have to associate an event (the same) to them. I use AddHandler button.click, AddressOf mysub.The issue is that mysub gets a string (mysub(string)), but AddressOf doesn't accept a parameter inside the routine. How can I do this? Using also an alternative to AddressOf.
EDIT:
Public Class Form1
...
Private Sub mysub(ByVal sender As Object, ByVal e As System.EventArgs, ByVal str As String)[code]......

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 method which requires a parameter to be passed in. I would like to use the Addhandler to call the method through a dynamically created button control's click event.
When I include () in the AddressOf, VS complains: 'AddressOf' operand must be the name of a method (without parentheses).
When I exclude the brackets, VS complains: Method '...' does not have a signature compatible with delegate...

The string itself contains things like "random" & random.next(1,3) & "random2" etc. The string registers all of this as a string and doesn't actually calculate random numbers.Is there any way to fix this?

Using VB.NET, Is there a way to do this RegEx call in 1 step... instead of 2-3? I'm trying to find the word "bingo", or whatever is between the START and END words, but then also inside the inner FISH and CAKES words. My final results should be just "bingo".
Dim s1 As String = "START (random string) FISH bingo CAKES (random string) END"

I am not the one who developed this tool, it's the previous programmer and they gave the project to me to update it however, when I try to run the application in my local computer I am getting this error: Argument not specified for parameter 'XLSFile' of 'Public Sub New(XMLFile As String, XLSFile As String)'.
The error points to the code below in bold letter:
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click

This function doesn't work if I change the input argument 'pdu' from a string to an int.Would someone please help me figure out what to do here so that the checksum does not add the ascii value of the int argument but rather the actual integer value?I took out a few lines of the actual function but it adds the input argument to a packet sent out via TCP protocol.This function shows the integer value just fine in the string that gets encoded as a byte array. the checksum is wrong.!
''Public Function buildpacket(pdu As Integer) is what I want.

Outlook is causing some problems when being passed a mailto string with accented characters in it. Changing the codepage for my entire webpage that has this string on it solves this problem, but that causes other problems in the system, so I would not like to do that.
A string like such returns a lot of garbage characters:
"mailto:Helpdesk-someemail@email.com?subject=Mon bâtiment / Départementé / Bureau n'est pas répertorié"
Meanwhile, this cuts off the character after the "D"
"mailto:someemail@email.com?subject=Mon bâtiment / Départementé / Bureau n'est pas répertorié"

As the title says I have a form with many databound textboxes. some of these boxes have data in them and some are empty. I need to add them altogether, so far all of the conversion methods I have tried err out when they run into an empty string, except Val, but then Val won't handle the string with a $ in it. I've tried decimal.parse which handles the $ but not the empty string. So I seem to be in circle that I can't get out of.

I've got a little function that just changes empty and null strings to "null":
Public Function CatchString(ByVal stringValue As String) As String
If stringValue = "" Or stringValue Is Nothing Or stringValue Is DBNull.Value Then
Return "null"[code].....
I added the bit about DBNull because sometimes it gets null values from a database. This doesn't work, though, because it won't take DBNull as a parameter.I tried changing the stringValue parameter from a string to an object, but then the If statement gives this error:
Quote: Object reference not set to an instance of an object.How do I make the function accept DBNull as a parameter?

We have a legacy component that has been converted from VB6 to VB.Net.The VB component was called from an ASPX page using Request("param") to pass optional parameters to function calls. That means the value is null/nothing if the parameter is not present.The parameters were then added to an ADODB call of a store procedure using Parameters.Append.When used from VB6 missing, Request("param") values were coerced into empty strings when passed to the VB6 component. This meant that the ADODB call was satisfied (for required parameters).When the code was ported to VB.Net, the null Request("param") values are now passed as null values (VB nothing?) and Parameters.Append skips adding the value if it is nothing. This caused the stored procedure calls to break as a required param was missing.
If we change the component's function parameters to be optional and have paramname as string = "" defaults, will a null/nothing value be converted to an empty string, or is null/nothing treated differently to a parameter being simply missing?

I'm working with referenced VB6 DLL's. The problem is that the results of a method/function call are not the same. Below the code examples:
First VB.Net Dim Validations() As String myErr = myEntry.ValidateLine(Validations)
When validation fails, the string array Validations is filled with the error description string. I've tried to accomplish the same in C#:
private string[] valArray = null;
sdkError = sdkEntry.ValidateLine(valArray);
Does anyone have an idea why I can't get C# to fill the string array? Additionally, the function in VB is called with ref to a System.Array ValidateLine(ref System.Array ValErrors), perhaps it has something to do with this?
