Access A WindowForm Element From A Class Function?

Sep 8, 2010

I work in MS Visual Studio 2008, I have a VB.NET Solution which has three Projects, BusinessObjectLibrary (object properties), DataAccessLibrary (object functions such as selectAll, exportToExcel) and WindowUserInterface (UserForms c/w Controls)In my WindowUserInterface (project) I have a form called "rolFormGrid.vb", on this form, I have a DataGrid that gets filled with a function called "selectAll" when the form is loaded, I also have a button that calls the function "exportToExcel" and I have a Progress Bar called "rolProgressBar" ***.

In my DataAccessLibray (project) I have a class called "ROL_Adapter.vb", and in this class resides the function called "exportToExcel" which has all the code to create an Excel Workbook. When this function is being called, it can takes close to a minute to export to excel. We all know how users can be impatient if they do not see anything happening in the foreground when an application is working, that is the reason I want the progress bar.

How To Access A Function In Another Class

Feb 7, 2012

So, I am reorganizing a winform application I wrote to make it more readable and maintainable. The previous structure I used had:

1- a login form with some connection objects

2- an import process start form with some import objects

3- a log writer class that receives data from the import process and writes a log file at the end of the import process

The code quickly got too messy, so my goal now is:

1- a login form with only form events

2- an import form with only form events

3- a class with all the functions

Basically, my class with all the functions (3) looks like this:

Public Class MyProgramMainClass
Public Function test()
Dim testing As String = "test"

Get Exception When Trying To Access FormValues() Element?

Oct 8, 2010

The exception:

"Input string was not in a correct format."

Appears when I try to access a field on my page like this:

.TransmissionId = IIf(FormValues("TransmissionId").Length > 0, Integer.Parse(FormValues("TransmissionId")), 0)

However it works for another field which is the same exact type of field, accessed like this:

.StateId = IIf(FormValues("StateId").Length > 0, Integer.Parse(FormValues("StateId")), 0)

Where could the mismatch and exception be coming from? What could be the fault? The field doesn't have a value when I'm pulling it. Do I have to test for a value different for this number field than I would have to for a text field?

Access To Object Passed ByRef In The Constructor Of A Class Through Another Part Of The Class?

Aug 18, 2009

I have some classes, BsfciFile and StudyFlashCard. Bsfci is the extension to which I save my set of flashcards in an INI format. I am currently working to transform my code from using Windows API calls to access the INI to using a IniFile class that I found on the internet. I would like the BsfciFile to have a Array of StudyFlashCard objects, but I would like the StudyFlashCard class to use the IniFile class object contained in the BsfciFile class. I can pass the IniFile from the BsfciFile class to the constructor for the StudyFlashCard class, but I want it to modify the same IniFile as the BsfciFile class has later on.

Asp.net - Element 'system.webServer' Has Invalid Child Element 'rewrite'?

Feb 14, 2012

I have a number of rewrite rules for a lot of things that I did in IIS7, like removing trailing slashes, canonnical URLs, lowercase lettering, and such. IIS altered my web.config, and everything works fine on the website, like it should. But in the Visual Studio web.config, the opening < rewrite > statement is underlined in blue, and at the bottom of VS, it says that the element 'system.webServer' has invalid child element 'rewrite'. But this is how IIS made it. I didn't do this manually. Should I be concerned with this VS error, or should I just leave as be, since it's working how it should work? Here's an example of my web.config:

Problem:
A parent class has a sub class with various properties. A property of the parent class is a List(of T) with T = the sub class The issue is how to store data in the sub class of the instantiated parent

Some example code (hopefully formatted correctly):

Intellisense does not seem to be seeing my class and I am not sure why. I am using VB.NET which I am admittedly not that familiar with as compared to C#. Perhaps I am missing something. I would bet it has something to do with something I am missing in VB.NET.Here is my simple class (for testing):
