What happen with that control ? It merely hide or disposed from memory away ?
The visible property has gone missing from properties. It still appears when your clicked on a textbox or label etc, just not when u have the form selected. Also doing it by code is not working e.g. form1.visible = false. Does anyone know what may have happened and/or how to get it back.

Now what happened that it gave error while saving data because the programme took as ItemId field is missing for the information to save in table.When i set the Visible property of Combobox as True the programme works fine.How i can hide Combobox ItemId without interrupting the programme to save data.

I'm using VS2008 and have created a dll with the following

I'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?
View 5 RepliesI 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 RepliesWinForms. 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]
View 2 RepliesCan someone clarify if there is ever a need for the below?
When setting a textbox "Visible" property to False is there any reason why I should also set the "Enabled" property to false.
I have a listbox with several list items added. I want that as user click on an item, I should be able to show its property. This should change for different items. For example (hypothetical) : Listbox has numbers 1 - 10. Now when I select 1 I should be able to set property - Name, Lastname, Colour, Age.
When I select 2 I should be able to set - Age, Hair Colour (clr shows), Weight, Date. When I select 3 then - City (combo box drop down), Country, Age only. This way value changes for diff items. One way is to put them in property grid and show them. Though this looks nice but adding/removing items in that is not easy. You need to have a class that refer that to prop grid. Do I have to code for each classes for all values in listbox or is there an easier way to manage items in property grid. If you think prop grid is not the right tool for such an activity then can you suggest something else.
I 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...]
I 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?
I 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]...
I 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 1 RepliesI 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.
I was just wondering if it is possible to apply an attribute to a property within a business object (MyBusinessObject) such that after the DataSource of a grid is set to a List(Of MyBusinessObject), the visible property of the column will automatically be false. For example:
myGrid.DataSource = New List(Of MyBusinessObject)

Form 1:

Okay, so I'm doing a card game and I'm trying to set that when picturebox (PictureBox1) is clicked, a random card from 13 cards will come visible. Problem is, that when i start the program and click the picturebox, the same card will always come visible. As you can see i've put a button (Button1) which will hide every card. If I press Button2, then Button1 and then the PictureBox1 it will show differend card, but the cards which come visible are always the same.
e.g i press PictureBox1 (which will make card visible), then Button1 (which will make PictureBox1 non-enabled) and then Button2 (which will hide every card and make PictureBox1 pressable). Lets say i pressed the PictureBox1 four times and i got cards: 9, 6, 7, 3, then I close the program, start it again and press PictureBox1 again 4 times and it will show the same cards (9, 6, 7, 3). How can this be done that it will not show the same cards always?
Here's my code...
Public Class Form1
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
End

I understand the properties to change a button from visible to invisible, but I need to be able to have two buttons alternate visibility when the first button is clicked.It's for a game. The first button is to "Begin Game" and on open, the invisible button that sits over it is called "Begin Again" which I would like to only appear once the Begin Game button has already been clicked. This would then trigger the "Begin Game" to become invisible.
