Test A Control Visible Property?
Mar 1, 2012I'm using Access 2010 and would like to know if there is a way to test whether a command button's visible property is True or False? If there is, am I right to suppose it would be the same for any control?

Sep 16, 2011I have written a Visual Studio 2008 addin that adds controls to a Form. I want some of those controls' Visible property set to False so they're hidden during runtime, so I do this:[code..]
This doesn't work. Not only is the control invisible in the designer window itself, but the Visible = False code doesn't even make it into [FormName].designer.vb. I have tried forcing Serialization on the Visible property like so, to no avail:[code...]
Turn A Control's Visible Property To True Or False?
Aug 11, 2011I know how to turn a control's visible property to true or false, the only thing I don't know is: If I have, for instance, 40 group boxes in which only one is visible, when I click on a button, the first group box visible = false and the second group box visible = true, and when I click on it again, the second group box visible = false and the third group box visible = true, and so on I don't want to write the codes for every controls, since it will be quite time consuming, I want to use fewer codes to achieve this objective,
View 10 RepliesVB GridView Control Does Not Allow Code To Access Column When Column Has Visible Property Set To False
Apr 1, 2010VB GridView control will not allow code in the vb code file to access a data column that has its visible property set to false. When it is set to true, the data column can be accessed with no problem. Any suggestions as to how to correct this? I have looked through the documentation, text books, and I have not found anything that gave me any clue as to what the problem could be. I thought that the property was just applied to the column, not that it would remove the column from being accessible.

View 4 RepliesVS 2008 Property Only Visible During DEBUG
Aug 21, 2009I have a UserControl that retrieves a bunch of data from a database. It uses the current date as one parameter to determine which data to show.
The database however is a little old and has no data available after April 2009, so while debugging I cannot get any data and hence I can't test the control.
As a solution I simply used a date in the past instead of the current date, just so I could see some data. Obviously, this has to be changed in the release version of the application, but I'm worried it will be forgotten, leaving the control completely broken, and worst of all, it's very hard to tell that it is returning the wrong data, so the users won't see the problem at all.
Now, I'm looking for a way to change the date used during run-time. A property in the UserControl would be the best solution for me. I could have a property UseTestDate or something, and if that was True, the test date was used. It would be set to False by default, so that the regular date is used by default.
The application has a Property Grid which is used to change the properties of the UserControl, so that's how the (test!) user can change this property. He can choose to show the current date (but there probably won't be any data preset), or he can set the UseTestDate property to True and get some old data.
The problem, obviously, is that the end user in the final application will also see this property in the grid! I don't want that obviously, there is no need for them to use a test date.
So I am looking for a way to make this property visible only when the application is run in DEBUG mode (via the VS IDE). I can make a property invisible simply by setting the Browsable attribute to False. I simply don't know when to set this. The attributes only allow a constant, so I cannot use a variable that is True when the application is in debug mode or something.
I tried simply putting the whole property between a conditional compile statement:
#If DEBUG Then
Private _UseTestDate As Boolean
Public Property UseTestDate() As Boolean
[code]...
I am able to Run the application in debug mode, even though there is the error that UseTestDate cannot be found. It seems that the property can be found when I run it (which makes sense of course, as it's only compiled when in debug mode). However, using that code I am unable to Build the application so I can run the executable; the error does not 'vanish' then...
So, how can I build an application that uses a property that is only compiled when the application is run in debug mode?

View 1 RepliesCovering One Group Box With Another And Using Visible Property To Display One
May 2, 2012WinForms. VB.NET VS 2010 Professional. So I am building a form that has 3 radio buttons on one side of it.Then on the left side I have 2 group boxes named Group1 and Group2 for this question that I have placed in the designer so that the one covers the other one and have set both of the groupboxes visible property to false.. When a user click on the second radio box group1.visible changes to true and group2.Visible changes to false.. When a user clicks on the third radio group1.visible changes to false and group2.visible changes to true. If the user clicks the first radio button both group1 and group2 visible changes to false.Only one of the group boxes shows.If I open the designer and ONLY change which one is on the bottom then it will show and not the other.[code]

Make Program Property Visible Only Within Specific Namespace?
Apr 20, 2009I got some set of base classes within one namespace and few sets of derived classes in other namespaces. Everything in one project.[code]...
OK, it can be done declaring .SubElements as Protected in BaseElement class. But in this case I cannot access this property from other classes in Base namespace that are not derived from it.
I tried adding Friend keyword, but it made this property visible when I'm instantiating derived classes too.
So... any way to hide some properties when using derived classes while being able to use them using base class?
Panel's Visible Property Won't Change From 'False' To 'True'
Mar 25, 2012I am stumped on this one. I have a panel (pnlKeyPad) that won't change the visible property when I try to set it to True. But when I try to set the Dock Property to DockStyle.Fill it succeeds. I have tried them in different orders, setting the parent property to the splitpanel and nothing seems to fix it. The panel is on a splitpanel that is visible. The panel is set to visible = false by default.
Any ideas of why this panel won't switch to visible when I specifically set it to visible?[code]...

Apr 11, 2010I want to alter the .visible property of a label based on if a variable is positive or negative (Hiding it for negative values)
But I want to do this for lots of labels so If Statements are too bulky.
I tried this:
Label1.visible = CBool(IntVariable1)
But it turns out CBool returns True for ANY value and False for Zero.I'd assumed it would be True for positive values and False for negatives.How can I do it without if statements?I considered Modulo or SquareRoots to somehow convert a negative number into zero, but didn't want to complicate things with imaginary numbers.
