Dynamically Allocate Group Boxes & Buttons
Mar 10, 2012
I am currently trying to allocate a number of group boxes dynamically. Previously (in other languages) when I have carried out something like this I have used the '&' to substitute the contents of the variable direct into the code I.E
For I = 1 to 20
Groupboxname = "GroupBox"+I
Weatherstates.&groupbox.controlls.add(obutton)
next
This would then have the result of creating a button in all the group boxes, however this does not appear to work in VB .net 2010
I have looked at Directcast, but i am a even more confused. Is there a simple way to substitute the contents of a variable into the code ?

I am having trouble coming up with a way to add a selected radio button in a selected group box together.I have 3 group boxes each accessed by a checkbox within each group box there is 3 to 4 radio buttons. I would like to know how to add the selected radio buttons in each group box together and display them in a textbox by clicking a button "calculate". I believe I would have to make a global variable but I dont know where to start.
Private Sub Calculate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Calculatebtn.Click
Dim answer As String
[code]....
I know this code is wrong but I was just trying to remember the calculate function.Is there a command that uses the selected radio button from the group boxes then I would be able to input that into my calculate button sub?

I understand because it has to be ON/OFF it won't go through to any other radio buttons in the group box. Would the best way is to use a hidden radio button that would switch control between the two? There's only two radio buttons i need to tab through, what's the best way to tackle this?

A friend and I are working on a project where we're required to build a reliable UDPclient/server using VB.Net. We have things working well, but one thing that still eludes us is how to dynamically allocate a (byte) buffer for the incoming data. Right now we have to hard code a maximum value/MTU (or use a really large buffer size and resize it once we've finished receiving). Does anyone know of a way that this can be done without needing to specify the receive buffer size?
Basically, before calling the receive function on the socket with a buffer of size x, we want to know x so we can allocate an appropriately sized buffer. Perhaps this is a problem in all socket programing that you just have to deal with??

Is there a better way to make a form with multiple buttons opening different things than having a form that has lots group boxes for each tab. So in the begining each box will be invisible and when you click the button the corresponding group box will become visible. Is there any other way?It will be like a background image and it'll have buttons that will mask it with invisible buttons. when the button is clicked it will open the corresponding group box.

I have this code.
Code:
Public Class Form1
Dim NPB As Button
Dim x As Integer
[code]....
As you can see, when I open a program from my menu, a new button will be created with text similar to this, "C:Program ". The button it self will not do anything. How can I create the method at the same time the button it is for is created? Also how can I change the text do that it gives me, for example, CCleaner.exe instead of the whole target path?

I have some operations of Picture Boxes etc being performed. After the user finishes with the formatting, I want to give the user an option to print the work.But its the work is not done on the Rich Text Box but on picture boxes. I am not even sure, how many of the picture boxes would be there after the user finishes the job, since I have provided option for dynamically creating picture boxes as well.

I have a groupbox with 12 checkboxes(containing months of the year). I need to calculate and display the value in a text box.
For example if one check box is checked then on clicking the button calculate, it should be able to display the value 500 in the text box, if two checkboxes is checked then the total should be 1000, if three check boxes then total should be 1500 and so on[code]...

The other day I needed to know how to handle a group of form items in one function, specifically speaking I needed to uncheck all ListBoxes in a group of a MenuStrip when any other was checked. Now I need something similar, except this time it's just a group of check boxes on a panel. heres the code I used for the other purpose.

I have a form that has group boxes of various controls for data input. One of the group boxes contains a user control. This user control can be 1 of 7 I have depending on the type of data I wish my user to load. The 7 user controls are all of various size. My form is a fixed size, and i have allowed room for the user control to fit the largest. However, the smallest one has a lot of space obviously. The resizing of the form itself I am struggling with. It has to be the size it is at now as there is a tab control,

New user here using VB .Net 2008
I seem to be having trouble getting group boxes to appear when I click a radio button.
For example:
If radiobutton1.Checked Then
Groupbox1.Visible = True
Groupbox2.Visible = False
Groupbox3.Visible = False
Groupbox4.Visible = False
End If
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:
If radiobutton2.Checked Then
Groupbox2.Visible = True
Groupbox1.Visible = False
Groupbox3.Visible = False
Groupbox4.Visible = False
End If
The second groupbox does not appear and is directly behind the first groupbox.
The .Top code doesn't seem to be working either.

I put some group boxes on a user interface and now labels and pictures that are set to visible can't be seen even when the group box is set to visible = false. (I have the group box and the pictures and labels in the same place on the form and was planning on using buttons to make them visible and invisible but the pictures and labels stay invisible no matter what while being in the same place as the group box.)
Does anyone know why group boxes do a sound job of making things invisible and how to correct it?

Im attempting to loop through all the text boxes inside of a group box, and add the text into a list box to later be written to a text file. Here is the code I am using.
Dim cControl As Control
Dim FILE_NAME As String = "Tester.efw"
Dim Group As GroupBox
[code]....
Now instead of locating only the text boxes, apparently it is still trying to identify the labels as text boxes, because I am getting this error:Unable to cast object of type 'System.Windows.Forms.Label' to type 'System.Windows.Forms.GroupBox'.

How would I dynamically enable/disable group boxes based on a radio button selection? I am trying to do it with two group boxes. The group boxes are called grpSelectChars and grpPWAutomatic. The radio buttons are called rdoChooseChars and rdoRandomlyGen. if rdoChooseChars is selected then I want grpSelectChars Enabled and grpPWAutomatic Disabled. in the load sub I have rdoChooseChars Checked
Private Sub PWGenerator_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
rdoChooseChars.Checked = True
If rdoChooseChars.Checked Then

say I have a Button1 subroutine
[code]...
I have a lot of such buttons in my main form. They all do the same thing like this. get the text and pass to some other routine. If i have 20 buttons, then i will have 20 such subroutines. Is there a better (or standard way) to do this without creating that many subroutines?

So I have 2 panels and the same number of radio buttons added programatically in each panel. For ex.
RB1 -> Panel1
RB2 -> Panel1
RBo1 -> Panel2
RBo2 -> Panel2
I want to group RB1 and RBo1 and RB2 and RBo2, but when I add the radio buttons to the different panels they group each other. I tried adding RB1 and RBo2 to the same GroupBox but could not achieve the goal either. Is it possible to manually link the radio buttons?

It appears to me to be right but always returns true.

Dim textboxes = groupboxes.SelectMany(Function(groupbox)

I have written a code and tried linking up groupboxes from my input form called input.vb and the output form called results.vb.
[Code]...
I have used the above codes to access groupboxes from both forms. However, at run time I get errors saying "InvalidCastException was unhandled" and below that it says "Conversion from string to DOuble is not valid". This error points to a value in a group box that is actually hidden or disabled.

I would like to have a single subroutine to service a group of radio buttons. I am interested in .CheckedChanged event. Right now, if I bunch them all into one routine, it gets called twice. One for the button that is checked and one for the button that is unchecked.

How can I set a verification that something is checked in a set of radio buttons within a group box? So... groupbox1 has rad1, rad2, rad3. I want to verify that at least one of them is checked. I was going to do a select case, but I can't figure the syntax for the cases... Visual Studio 2008, btw

I am attempting to make the transition from VB6 to .net
I have a group box with 6 radio buttons. I want to perform a function when 1 of those buttons are clicked.
In VB6, I would have set up a control array and ran the routine when the array was clicked....but I am struggling with .net here, since there appears to not be control arrays at design time.
Is there 1 even I can use, or do I have to go into each radio button and code the individual event?

I'm fiddling around with trying to make a sort of map/world. I'm using 16 x 16 pictureboxes named PictureBox1, PictureBox2, etcThe issue is that when I put the images into all the pictureboxes, I have to have a line for each picturebox (so say I have 100 boxes, I have 100 lines).The only difference in each line is the picturebox number, the rest is identical. I'm basically telling it to set that picturebox's image based on the number that a variable I've created has stored.I've got a game idea, and I'm just trying to figure out how to do the map. I want it to work like the old school RPG games like Dragon Warrior, or the more recent Dwarf Fortress. I'm still not sure if I want to use graphics or letters. At this point, I'm just trying to figure out how I can create the main screen where the user moves around. This is what I've come up with, as it works with what I know. I'm pretty new to this, although I've messed around with VB6 a lot.
Dim tile(30) As Integer
Dim tilelocation(3) As String
Dim x As Integer

So basically what I'm trying to do is write data from an XML file (a "save file") back into the form. My controls are in all different group boxes (makes it much easier for showing and hiding groups of controls dynamically). I thought about and am putting each control's Parent name into the file, but can't figure out how to get that parent name back into the DirectCast within a For...Next loop so it will actually cast the data into the control.

I'm creating a windows form application, which contains radio buttons, that when checked and the button is clicked, display a certain image in an image box based on which radio button was checked. I'm having trouble with assigning the certain image to the radio button. Can I use If/ElseIf statements?
