Make A Groupbox Invisible But Have It's Contents Visible?

Jan 13, 2012

In visual basic.net I have been playing around with groupboxes and things of that nature, is there any way to group items into a box, say, buttons, and use the groupbox as a container to move / hold all of its contents while not being visible in any way? (no decoration perhaps?)

I've tried making the groupbox invisible but that makes all the items within the groupbox invisible as well.

Make Multiple Controls Visible Or Invisible On A Form?

Jun 2, 2011

Still using VS 2005. My concept is to use the same form space to display different "pages", like a "wizard" where you click the [Next] button, and the current UI disappears and a new UI appears. I want to "turn off" multiple controls and "turn on" multiple other controls. Example code: -

Private Sub
Button4_Click(ByVal
sender

Objects Set To Nothing After Changing Forms?

Dec 19, 2010

In form frmAddPlayers I declare and create an array of pictureboxes in the Load event using the code:

Dim
pbxPlayerJoined(7) As
PictureBox

[code]....

In the watch window the value of the pictureboxes is System.Windows.Forms.PictureBox. Later in the load event I start a background worker in form sfrmUSBDevice using the code:

sfrmUSBDevice.sReadWriteThread.RunWorkerAsync()

The background worker waits for user input and then calls a subroutine from form frmAddPlayers. The subroutine changes the image in the picturebox to indicate that the user input has taken place. However when the debugger returns from sfrmUSBDevice to frmAddPlayers the watch window shows that all of the pictureboxes have a value of nothing. Then when I try to change the image of the picturebox I get an "Object reference not set to an instance of an object" exception. It seems like when the debugger goes to the sfrmUSBDevice form and comes back to frmAddPlayers the objects on frmAddPlayers have lost their information.

Linq To Objects - (C#) Creating A Dictionary From An Existing List Without Looping?

Aug 31, 2011

I don't know if this is doable, maybe with Linq, but I have a List(Of MyType):

Public Class MyType
Property key As Char
Property description As String
End Class

And I want to create a Dictionary(Of Char, MyType) using the key field as the dictionary keys and the values in the List as the dictionary values, with something like:

New Dictionary(Of Char, MyType)(??)

Even if this is doable, internally it will loop through all the List items, I guess?

Changing Visibility Of Objects Without Using MDI Forms?

Nov 26, 2009

Currently my program randomly removes words from a set of text and inserts textboxes below the text. The user can then enter his/her answers in the new textboxes. What I would like to do is set the program so the user can have two choices one being Easy and other being Advanced. Then when the user hits either button it brings up everything that is currently on the form. I'd prefer to do this without having to use MDI forms. I've had a hard time using the MDI forms and therefore would like to avoid using them. They way I was thinking this could work is all objects would remain invisible except for the 2 buttons and then when you hit one of them they disappear and everything else appears.

Child Objects Raising Events In Parent Objects?

May 1, 2009

long story short, I have created a ListView type control, using UserControls for the parent control and the ListViewItems. Most the of the control is written and works fine, right up to the point where I tried to replicate the 'Control.SelectedItems(0).Index' property and the 'SelectedIndexChanged' event.

Each child object knows its index value, and could pass this value via the SelectedIndexChanged event (assuming this is how it works in a normal ListView control -- user clicks on an item, and that item fires an event updating the selected index value in the parent object).

How does the child object raise an event in the parent object? I have a feeling this could be done with Delegates, but I'm still learning about their usage.

Make Reletion Between Objects?

May 12, 2012

I made a program to generate random numbers and the result will be in two boxes. The first box contains 16 numbers and the second one contains 32 numbers. I need to add a diagram show the relationship between these numbers. The diagram must contain ten fixed objects numbered from 0 to 9 and the code should start reading from the result box from left to right. for example: we have a result [1502219785642556], so object number one its color will be changed to be known that it is the first number then the second number is five so there will be an arrow goes from object number 1 to object number 5, then arrow from 5 to 0, arrow from 0 to 2, from 2 to 2 cycle arrow.It better to designee the objects in three rows and columns, and each arrow has a number in sequence.
