I am trying to create a Public Sub / Function that will allow me to pass certain variables into it and this will affect the output. e.g.
DIV ID = InfoDiv
CSS Class = "Warning"
LBInfoMsg.Text = "An Error has occured"
DIV Visibility = True or False
I would like to type something similar in the code behind page:
InfoMsg(InfoDiv, "warning", "An Error has Occurred", True)
Public Sub InfMsg(ByRef MyDIV As System.Web.UI.HtmlControls.HtmlGenericControl, ByRef CSS As System.Web.UI.WebControls.Style, ByVal strMessage As String)
strMessage = strMessage.Replace("'", "''")
MyDIV.Attributes.Add("Style", "warning")
MyDIV.Visible = "True"
End Sub
Class A gets, as part of it's constructor, a pointer to class B and saves that pointer in a private variable. Class B exposes a public function, F. I'd like for class A and all classes that inherit from class A to NOT be able to call B.F.The idea is that class A will implement its own version of F, one that calls B.F, but the rest of the code should not be calling B.F. If it matters, the two have different function signatures.Maybe another way, like a class C that inherits from class B and hides the public functions? (Cant that even be done?)
View 2 RepliesI have a public function declared in my code-beside on default.aspx.vb. I needed to add a second page to my project and copied and pasted that function into the second page, but when I test the page I get an error saying there's a conflict with the same public function on the default page.
If I remove the function from the second page, i don't get the error, but will it still be accessible if called on that page, even though it's on the default page? Or do I need to place it somewhere else so that it's accessible to both pages?
I have a Function for checking the input in a textbox and only allowing Numeric & Backspace; everything works fine so far. My form is for financials and it has about 20 textboxes; they all receive Numeric only data; there is NO alpha data on the entire form required. Note in the snippet below that I don't even need a decimal point as well.
Is there a way to handle ALL textboxes on this form without having to place the Function call in each textbox KeyPress event. took a long (5 year) hiatus from developing VB6

I have a situation where I have several VB.NET Modules in the same Logical-Module of a large application. I would like the update function of each module to be public, but I would like users to be forced to qualify the function call with the module name.

Update()
Is this possible?

I am trying to do a simple program where I have a public structure and public function in a code file, the problem is I want to return two integers. Here is the code from my code file.

I have a windows app that references a web service I created. In the web service, I created a function that needed to return more than one value. Because of this, I created a public structure in the web service:
Public Structure MyRecordSet
Public lstOfDataInRecord As List(Of String)
Public iNumberOfRecords As Integer
End Structure
Here's the function - the return value is MyNewRecordSet:
Dim MyNewRecordSet As MyRecordSet <WebMethod()> _
Public Function GetDataReturnList(ByVal sql As String, ByVal sTableName As String) As MyRecordSet
MyNewRecordSet.lstOfDataInRecord = New List(Of String)
[Code] .....
Anyway, I see it's a conversion issue, but not sure how to resolve it. This is my first attempt to use a public structure in a web service and receive a return on it from my app.
why I am getting a NULL reference error. Form: Public Sub CreateSession() ' This will be the execution function after the date, provider, session type, session number ' and consumers have been entered. Each Consumer will have it's own tabpage and seperate record.

I'm struggling with a thing or two...and i've read some stuff about the backgroundworker but im stuck Basically what i have is a : PUBLIC FUNCTION TEST (path as string) : which at the end of work , adds an item to the form1.listbox. That works quite nice but freezes the app. I've tried using the backgroundworker, the function in the background worker seems to work nicely, the bad thing is that i dont get any results in the form1.listbox.

I have tested the variables in the Functions and the are correct.
I have a math program that I am working on. One of the exercises has a random word and 6 radiobuttons. The user has to select the radiobutton that displays the exact number of letters in the random word. What I am having trouble with is creating a Public Function to check if the answer selected is the correct one. The radio buttons are within a groupbox. The Public Function returns a boolean True or False.

During a code review I looked at set of repository classes (in vb.net). I am used to seeing these repository classes full of functions that return collections (among other things) of your domain objects. However, this repository had 1 public property and 1 private variable that looked something like this:
Private _item as Collection (of Customer)
Public Item as Collection (of Customer)
Get...
Set...
In the "Get", there is code that gets a the Customers from the DAL and loads it in the private _item. What would the benefits be in using a property (customerRepository.Item) instead of plain old function (customerRepository.GetAllCustomers)? The "Property" way looks odd to me but odd doesn't always mean wrong.
I am having a toolstrip in the mdi form which contains save, update delete and clear buttons.
