Use A Variable's Contents As The AddressOf A AddHandler?
Aug 26, 2009
I have method that I execute many times.In this method I have the following AddHandler.
AddHandler mi.Click, AddressOf Context_SortDescending
I would like to replace "Context_SortDescending" with a variable that has the value "Context_SortDescending".I tried using:
Dim methodName as String = "Context_SortDescending"
AddHandler mi.Click, AddressOf methodName
This received an error (AddressOf operand must be the name of a method).

My current issue which I've been stumped on is incrementing variable names in a string.
Without reading my actual situation, I need to know if you there is a way to do the following:
Code
'Label1 is a label that exists in a userform and this code is entered into the UserForm_Initialize()
Dim X as String
[Code]....
The reason for my label1 example above is I believe that using my current methodology- if there is a way to convert a string contents to a variable name, it should do the trick.

I had a look through this forum and other forums but couldn't find what I was looking for. I am new to visual basic and have spent all day trying to find the solution to the following issue.I am creating objects from a class that store information about the user of the program. Each time a user signs up the program, I need the code to create a new instance of the class, creating an object and storing information about that user. The contents of this object will then be saved into a text file.

I have a structure named StudentData, it consists of a studentname, an array of testscoresand the student average. There is also an array of structure objects for a total of 6 students. I have the header, column heads, the student names and the averages printing when I click the print page event. I have tried multiple ways of setting this up to get the test scores to print, these are the structure array variables. When I put in the code to process the arrays testscores, I receive a run time error that I don't understand

While working with an excel file (.xlsx), the data I get from it is an IEnumerable(of Dictionary). When I bind this to my datagrid, I get the problem that I only see 2 columnsI've been tracing this problem and discovered that in the first row in the excel, there are only 2 values (cell C and D). I think the binding to datagrid looks at this first row to create its headers. This results in my datagrid only showing columns C and D.

I am trying to create a code where I placed sets of numbers in an array.I'll use a masktextbox to have the user enter the numbers to match what's in the array. If the user enters the number, ex: social, and the data is correct (matches the numbers in the array), something happens if the number entered in the masktextbox does not match any of the number sets in an array then another thing happens.The masktextbox so far only validates format and gets number only, however, I want the number entered to match whats in the array.

I 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?

I 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.

I'm loading a table within an UpdatePanel from a database where the first column contains a radio button.This is done within a DoWhile loop for each record read. Simple enough. I use AddressOf to set the handler for the radio button. The weird thing is that the FIRST radio button doesn't get the handler assigned (by checking View Page Source) but all the rest do. Here's some code:
