AddressOf With Parameter - Method Which Requires A Parameter To Be Passed In
Mar 1, 2009I 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...

Gets A String (mysub(string)), But AddressOf Doesn't Accept A Parameter Inside The Routine?
Aug 18, 2011I 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.

EventHandler AddressOf Invoke?
Apr 22, 2011I wish to check the hard drive space used in a folder on a hard drive. This will happen continuously as a service, so it will be calculating the space used for thousands of folders all the time. I know that this code can be done easily in dotnet, but it seems to take a really long time. Are there any APIs to do this more efficiently, or does the entire looping process have to occur to do this check?

Feb 19, 2009I am using the EnumWindows API Call, and I've looked at an API website. It can't convert a Delegate (from AddressOf) to a Long, so I made a delegate type for it. (Uh-oh, already.) I need to know something that will take the returned IntPtr and get the window title, so I can activate it with another API call and send some keys.

ToolTips, Parameter Options, And Parameter Groups For New Code?
Dec 10, 2008One of the things that I think is really cool about VB.NET is how built-in functions and subs have extra help text in their ToolTips like "Expression: String expression to search for replace string." as well as the usual "Replace(...parameters...) as string" text. So are the pop up boxes with things like "CompareMethod.Binary" or "CompareMethod.Text." And finally I like how some functions and subs have different sets of parameters for the same routine. For example, New FileStream() starts with either a path (string) parameter or handle parameter, but none of the 15 sets of parameters contain both path and handle parameters. Is there a way that I can set up the classes and functions I write to use these things or do they only work with built in classes and functions? If there is a way, what are the proper names for them so I can look them up in the VS/VB documentation? I would be happy enough if someone would give me an example of them, but it would be nicer if I could go through the documentation and find out if there are other cool things that are related or near by.
