Covering One Group Box With Another And Using Visible Property To Display One
May 2, 2012
WinForms. 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]

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.

I have a table in MsAccess with the fields CustId,ItemId,Description,Price,Amount.On a form in vb express..there is a combobox for ItemId which is already populated with the ItemIds of all the Description of Items. the program is running fine and it is saving data into table through a saveButton Click event.Since ItemId is not necessary to be visible to the User so i set the Visible property of Combobox as False. 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
Public Class Test
Private privatesampleProperty As String
Public Property SampleProperty() As String
Get
[code]....
From what I can see this should not be visible outside the class...

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?

I 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?

Can 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 2 group box components and both are same size,font,location and visible is false. When i click button2, the groupbox1 won't appear(the group box2 is on bottom n group box1 is on top).
Example:
button1
groupbox1.visible=false
groupbox2.visible=true
button2
groupbox1.visible=true
groupbox2.visible=false
Because i want to show the different,so the location have a little different(actually both are same location). I think my code is no problem. The problem i guess is both component cannot locate at same location?

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,

Using Visual Studio 2008 and VB.NET ...
I've created a form (OpaqueForm), which is an intermediary form between other forms which I will open with ShowDialog. The idea is that when I want to show a form using .ShowDialog, this OpaqueForm, with an opacity other than 100%, sits in between the main form and the dialog form, effectively "greying out" the underlying main form.
The OpaqueForm has the FormBorderStyle property set to None, and accepts in the constructor a Form object on which it invokes .ShowDialog. The effect works fine, but there is one caveat. The task bar is also covered by the OpaqueForm; I am assuming because it has a FormBorderStyle of None and a WindowState of Maximized.
I don't want the OpaqueForm to cover the Task Bar, because it would be impolite to have my modal form lock out a user from switching between tasks. How could I go about preventing OpaqueForm from covering the Task Bar, too, while still using a FormBorderStyle of None?

I have a main form that stays in the background of my program. Other windows open and are owned by the main form. Think of it as your desktop.It's not a MDI form; I can't use a MDI form for this project because it's too limited for me.

I have a form with a series of basic objects,, a list box a few buttons, a few text boxes and a few labels..
Anchor property works just fine on all of them except one text box and one label. The property is clearly SET on both objects and I can't, for the love of me, figure out what is making these two act "disobediently".

I'm experimenting with xml literals in vb.net and there's something I don't get. Here's a small sample that illustrates the problem. I'm adding two PropertyGroup nodes to an empty Visual Studio project. The first one is added as xml literal, the second as new XElement:
Imports <xmlns="[URL]">
Module MyModule
Sub Main()
Dim vbproj = <?xml version="1.0" encoding="utf-8"?>
<Project ToolsVersion="4.0" DefaultTargets="Build" xmlns="[URL]">
[Code] .....
This code writes the following output:
<Project ToolsVersion="4.0" DefaultTargets="Build" xmlns="[URL]">
<PropertyGroup xmlns="[URL]"></PropertyGroup>
<PropertyGroup />
</Project>
As you can see, the first PropertyGroup node contains a redundant xmlns declaration. Why is that, and can it be avoided?

I 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)
Public Class MyBusinessObject

this questions has be answered partially, but I can't find any full tutorial for this problem.I created my own user control (an advanced list with columns). Each column has different attributes like width, colour and text.I want to able to add this user control onto a form and select/edit the different attributes of each column. Hence, for each column in my user control (these columns are created beforehand, no columns can be added or removed from it) there should be a property in the property-menu. Each of these column-properties should be expanded (like the normal size-property in most default vb-controls that can be expanded with the little plus to show the width and height individually.What i mean by this, is: In the property-menu there should be attributes like Column1, Column2, Column3. Each of these attributes should be expanded to show the attributes like width or colour.
Currently I have different properties for different values of the same column, like Column1Wodth, Column1Colour, etc, but I want to group this under one value Column1.I think this is quite an easy solution, but forgive me, I spent more than 4 hours on google, but couldn't find a proper solution.

I want to create a game using visual basic 2010. I'm a specialist in VBA and Excel but not VB 2010.I want to display and hide a whole group of objects. In Acces I used for such cases the TabControl. For example in Tab1 the Game, in Tab2 the highscore and in Tab3 the options. Then I made it transparent, so that the Tabs (Buttons) are not visible, only the objects in Tab1 Tab2 and Tab3. With VBA I select the Tabs controlled by my own buttons (jpg). I tried the same in VB 2010. Without success.What can I do to switch between game, highscore and options without using popups. I want to display them at the same positions. So game objects and option objects should hide and highscore objects should be shown. And the other way round. Like the handling is with different layers in photoshop!
