View 6 RepliesI have a lot of radio buttons in a groupbox. Normally I will check each radio button individually using If radiobutton1.Checked = True Then.
But I think maybe there is smart way to check which radio button being checked in a groupbox.
I am trying to get a button or picture to be able to move in a groupbox with the click of a button while using a loop procedure. I need the object to be able to 'bounce' off of the edges instead of going off the screen, and I also need to be able to incorporate a timer with a limit based on what the user inputs. I am using Visual Basic 2005.

I'm creating a VB.NET application that includes two radio buttons inside of a groupbox. If the first radio button is selected, a certain tab on a tab form should be enabled. If the second radio button is selected, that tab should be disabled.
Is there a groupbox method that monitors both radio buttons and fires when the selection changes? Or do I need to set up individual methods for each radio button?
I've got a groupbox on my form. I changed its font and fore color. The problem is that when I add a button or any other controls like a label, checkbox etc to the groupbox, the controls are automatically changing their fore color and font to that of the groupbox. How to prevent this?

Is there any way, maybe with a specific reference to put a control that records what plays wmp activex and to save somewhere on your computer?
I'm using a CheckGroup in a project found here. There were several things in the code that needed fixing to really be useful to me:The fact that the panel in the regular groupbox overlapped the checkbox control so that the bottom of some letters were being cut off. When changing the back color of the groupbox, it didn't change the back color of the checkbox. Fixing these two problems was easy, but fixing the second one led to a new problem. When changing the backcolor of the groupbox to Transparent, it also changes the backcolor of the checkbox to Transparent, thus displaying the text for both the checkbox and the groupbox's header.
View 8 RepliesHere using VB .Net 2008. I seem to be having trouble getting group boxes to appear when I click a radio button.
For example:
CODE:
This indeed brings up the first radio button however I have other groupboxes underneath which with the same code will not appear when the radio button is checked.
Eg:
CODE:
The second groupbox does not appear and is directly behind the first groupbox. The Top code doesn't seem to be working either.
I'm from denmark and hope I can explain my question for you. This is just a example: I have a panel, let's say panel1 and another panel on that panel (panel2) and so on until for example panel5 - on panel5 I have a button (button1). Now I would like to change button1's backcolor property through code how do I then get access to button1, now it's a child-control on panel5 that is a child control on panel4 etc. ??

I have just completed an upgrade of a VB6 app to VB.net (2008). Everything works as it should except for one (essential) part. I cannot open more than one instance of the built app without getting a file access error. Now don't laugh but my program uses Random Access files to store the data (i know, i know the 1990's called and they want their programmer back). Anyway I've been using this method since the early 90's and it's never let me down. Until now that is. VB6 allowed any number of users to access the files but for some reason VB.net gives the following error: The process cannot access the file "C:lah blah" because it is being used by another process.

View 2 RepliesHere's an example of what I'm talking about...
Public Class Sample1
Public Shared Function MyValue() As Integer
Return 0
End Function
Public Sub Code()
[Code]...
Me.MyValue gives a warning in VB.NET and (the equivalent code gives) an error in C#. Is there a particular reason for this? I find it more intuitive/natural to access the shared function using 'Me.MyValue' - but I avoid it to keep my warnings at 0. Did someone else just decide 'Nah, it makes more sense to do it the other way' or is there some technical reason I don't understand?
EDIT: I was thinking of it wrong, more like a 'sub class' in OOP. Even if something is declared in the base class, you access it through the instance you have. But that relationship is not the same with shared or static.
The context of this question is that I am trying to debug performance issues (apart from the obvious ones I already know about and can find).I inherited a code base (VB.NET) for an ASP.NET app. This is an app that was developed way back in .NET 1.1 days, and was the first .NET app for a lot of the developers who worked on it.
In this code base is a class called DatabaseUtility that contains several Shared Public methods as well as non-Shared Public Functions and Subs for CRUD operations to the database (SQL Server).
It is common in my "BL" that a method creates an instance of the DatabaseUtility which essentially figures out what the connection string should be and opens a connection, as well as giving the developer a handle to the other methods contained within it.Dim utility as New DatabaseUtility()
Once I have that, I start to create parameters that I am going to pass to one of the methods in DatabaseUtility (like GetDataSet). There is a Shared method in my DatabaseUtility called CreateParameter which does essentially that. It creates a SqlParameter object so I can add it to a Parameters collection.
Now, the code base is littered with a lot of this:
utility.CreateParameter(...)However, because CreateParameter is a Shared method, I am not sure what is going on behind the scenes. I know because it is a Shared member that an instance of the DatabaseUtility is not created when I call it like this:DatabaseUtility.CreateParameter(...)
However, because I am calling it from an instance (utility), does that change the behavior at all?
I believe there wont be any diff if user clicks the button on the form and the click event is fired OR if we call the button click event / function in the code. Because in one my project, this does make diff. If I click the button on the form, the App works great but same button if I click it thru the form code, the whole process crashes. This happens in Vista / VB.net.
