VS 2008 Combining Private Subs Together?
Nov 5, 2010Probably an easy question to answer...I have 9 buttons on my form
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
etc. and all do the same thing so how can I merge them into the same sub so i don't have to copy and paste a bunch?

View 1 RepliesRemove "private Subs" From A Form?
Nov 20, 2010I was wondering if there is a way to remove "private subs" from a form. Many times I double-click the wrong button in the form, and that sub which pops up will stay in the code forever, which is making the code more messy.
Another thing is that if I change the name of a button in the buttons properties, the "Private sub button1_click..." in the code will always have the old name. Is there any way to update this name in the code?

Pass An Array Of String When A System.Array Is Expected?
Feb 24, 2009I am writing an OPC Client in VB.NET (2008) and I am using an OPC wrapper from Graybox. I am having some problems with the data types. I have an Array of String that contains all of the OPC Items that I wish to read from the OPC Server. When I attempt to use the Array of String, Option Strict causes the following compile error message:Error 5 Option Strict On disallows narrowing from type 'System.Array' to type '1-dimensional array of String' in copying the value of 'ByRef' parameter 'ItemIDs' back to the matching argument. How do I pass the Item ID's (all strings) in an array?
View 1 RepliesVS 2008 Overriding Subs
Jan 7, 2010I have an access database for steel members. Each table has a different type of member, and then in those tables, each size of that member type.
I am about to create a tool that draws these sections when they are selected, but as there are 12 different member types, I don't really want to have 12 different Subs for "Draw" that essentially do the same thing.
I considered polymorphism.. (I think I have it correct)

VS 2008 - BackgroundWorker Call Additional Subs?
Jul 7, 2009Can a BackgroundWorker call additional subs? In my program I am connectiong to an OPC Server. I am doing some AsynReads, which in themselves don't take anytime. But Once I get the AsyncReadComplete returned, I want to do the AsyncRead right away. Basically I need to Loop them. The problem now is that while it is doing this, Everything is unresponsive, because it is just going through the loop. So to perhaps rephrase the question, If the BackgroundWorker initiates a process (in this case AsyncRed) would the returned AsyncReadComplete be apart of the BackgroundWorker or seperate Thread?

VS 2008 Data In A Variable Not Transmitting Between Public Subs?
Nov 17, 2009Basicly I have a set of public subs, (not related to a form), inside a public class, and all of them share a variable. One of the subs, the one called for first gives the variable a value.
When the next sub is called, the variable is null. The data in the variable has been erased as the execution of the prior public sub ended I'm guessing.
VS 2008 Subs/Functions Intellisense Listing Values To Parameters Upon Using It
May 30, 2010I'm almost sure that I've seen this somewhere, but I can't find it anymore. Or maybe I'm imagining it, which would'nt be strange either.
When creating a sub or function and adding parameters used when calling it.
-Is it possible to list the parameters that I can enter when using it somewhere in my code?
E.g.
Public Sub MessageMain(ByVal Message As String, ByVal MessageType As String (List of possible values for MessageType)) Same for example as when you have boolean values in a sub/function. As soon as you use that somewhere in your code intellisense will present you with True/False to select.
I'd like the same for parameters in subs or functions I create and calling them from somewhere in my code. Saves me the trouble of remembering which options are available for those parameters.
