Cannot Clear ComboBoxes When Choosing Between RadioButton Options
May 21, 2010
I have 7 radioButton options that allows the user to select which "Group" of guitar tuning they want. For example "General" and Dropped" Tuning". When the user selects rbGeneral a comboboxTuning gets items.add ("Standard") and others added to it. The same goes for when the user selects "Dropped": the comboboxTuning gets filled withe different terms. The problem is....I cannot figure out how to clear out the combobox.items (text) when switching between "Group" radio buttons. So, the comboboxTuning just keeps filling up.

I have a program issue I am trying to work on. I have multiple comboboxes(12 total) on a form.I am attempting to update some settings from what ever the user selects from the combo boxes. I am trying to keep the code as small as possible, so I thought about having all the comboboxes have similar names only different by a number being changed at the end. (ex: cbo_1, cbo_2, cbo_3, etc...)And using a For next loop to advance through each combobox and update the settings as the for next loop advances.(This might be a stupid way of doing it, but its the first idea that came to mind.)

I'm using VB 2010 and I'm trying to use combo boxes on a current project but I'm not familiar with the code. I would like to set values to certain options in the combo box.
For example, if inside the combo box I listed the options:
Dog
Cat
Bird
I want dog to be set to = 1
cat = 5
bird = 12
To go further into depth, the code probably looks something like:
If cat.selected then
pet = 1

Maybe a windows form doesn't usually hold that many radio buttons. You only need so many;say four different sizes you would need a radio button for each one. In my case I have two GroupBox Containers each with 3 or 4 RadioButtons. If I have a reset button (giving the user a method of starting over) that clears any selections the user made, I have 7 lines to 'uncheck' each item individually.
Like this;
FirstRadioButton.Checked = False
SecondRadioButton.Checked = False

I have radio buttons set up with different prices behind them.
When I change the radio button, the label clears but continues to add on the last price from before, therefore giving the wrong "subtotal" as such.
I have tried Subtotal.Text = "" and Subtotal.Text = String.Empty but these only clear the label, not the number behind it.

I'm struggling to figure this out on my own. First of all I'm not sure if my calculations are right for the BusinessCustomer part. Its supposed to be:
Processing fee:$16.50
Basic service fee: $80 for first 10 connections; $4 for each additional connection
Premium channels: $50 per channel for any number of connections
anyways, what Im mainly concerned about is clearing the label when the radio buttons are changed. I have tried adding "Call Clear()" in certain event procedures with no luck. Does anyone have any advice or tips? Help is much appreciated. Thanks!

I am creating a program that make a person select different options and in other boxes it will populate the choice the person makes. Example is the program is fora car wash and if you choose standard or deluxe it will show in the other boxes what comes with that package.I got the program to work except when going to select a different option it still keeps the old info and displays the new info as well. I tried like at the bottom of the procedure Exteriorlist.Items.clear() and it would clear and never display the info. I am still working on the project I am trying to get the print option working properly I am just needing help in figuring out how to clear the info when I select a different package.
Public Class CarWash7
Const EXTERIOR1_String As String = "Hand Wash"
Const EXTERIOR2_String As String = "Hand Wax"

this is a subset of a previously posted problem, I have narrowed down my issue and am reposting a question from this thread: [URL] I have apparently confused the compiler by renaming some comboboxes in Visual Basic .net express? (See relevant code below) I think the confusion is in who should handle what, with two routines named with variations of ComboBox1 and one handling the other ( it confuses me just trying to interpret it mentally):

I have a form with 4 comboboxes and a button. The first combobox is enabled, but the rest of the controls are disabled. When the form is opened I fill the first combobox (cbxMethod) with a datatable. When the user selects something in cbxMethod the next combobox (cbxStudy) will be filled and so on. When the last combobox (cbxAnalyte) has a selected value I want to enable the button and give it focus so the user can move forward with the program. I basically want to force the user to move from one combobox to the other, until all are filled.I am currently using the SelectionValueChange event, but this event only fires when the user changes the value with their mouse or hits the Enter key, not when the user hits the Tab key.

I am in need of a form that shows various options, exactly like the Options in Visual Studio. Since there are so many options I too want them categorized, with a TreeView to the left taking care of showing the right category.The usual 'easy' approach here would be to just place a TreeView control on the form, add some nodes, and give those nodes a tag or key that corresponds to a panel or UserControl with the options for that category.Since there will be a lot of options however, this is not really feasible design-wise; the form would be cluttered with possibly 50 panels, all of which I would need to select and bring to front from time to time to add controls to them that represent the options.
So I decided to create a custom control that does exactly that. The control is very similar to my Wizard usercontrol, users can add OptionsPanels at design time, which inherit Panel and simply represent one panel of options. When they do, the panel is added to a container panel, and at the same time a TreeNode is added to a TreeView. The control uses a custom ControlDesigner to handle design-time clicks in the Treeview, selecting a different node would select and bring to front the corresponding panel, allowing the user to add the controls he wants.
Due to the design time support the problem of having 50 panels is no longer present, only one panel will be visible at a time and selecting the right panel is as simple as selecting the corresponding TreeNode, just as during run-time. Anyway, I got all this working, but only for a single 'level' of categories. As you can see in the Visual Studio options, there can be multiple levels of categories. For example, the Environment node has a bunch of children, where each child represents one 'options panel'. There can even be deeper nesting, see the Text Editor node for example.Let me begin by drawing out the basics of how my control works so far.
The main control is an OptionsView control, which contains a SplitContainer with a TreeView to the left and a OptionsPanelContainer to the right. The OptionsPanelContainer is merely a Panel to which only OptionsPanel controls can be added, and which raises events when this happens, as well as when OptionsPanels are removed from it. An OptionsPanel also inherits Panel, and these are the actual panels the users will see in the control, one for each option category.For now, each OptionsPanel has exactly one corresponding TreeNode (and vice versa). In the Visual Studio options, each 'parent' category usually has a 'General' node as the first child, and the parent and this General node show the same option panel, but I am ignoring that for the moment.
The OptionsView control has a property Panels that returns the ControlCollection (Controls property) of the OptionsPanelContainer (in other words: it returns a collection of OptionsPanels that are in this container panel).
vb.net
<Editor(GetType(Designers.OptionsPanelCollectionEditor), GetType(UITypeEditor))> _ <DesignerSerializationVisibility(DesignerSerializationVisibility.Content)> _ Public ReadOnly Property Panels As Control.ControlCollection Get Return Me.PanelContainer.Controls End Get End Property
A custom CollectionEditor for this property takes care of the designer: even though the property type is ControlCollection, the CollectionEditor knows it should create instances of the OptionsPanel control instead of just Controls.When it does this, a corresponding TreeNode is also created and its Tag property is set to the OptionsPanel. Vice versa, the Node property of the OptionsPanel is set to the node. Hence the node and panel both know their corresponding object.
vb.net
Public Class OptionsPanelCollectionEditor Inherits System.ComponentModel.Design.CollectionEditor Public Sub New(type As Type) MyBase.New(type) End Sub Protected Overrides Function CreateCollectionItemType() As System.Type
[code]....
So far so good, this all works fine. I can add Panels via the designer and when I do a new TreeNode appears in the TreeView. I can select this node and the panel becomes visible (comes to the front).Now, I am a little stuck. How do I implement child option panels? And more importantly: how do I let the user add child panels?The most logical choice I think is to let each OptionsPanel have a property (ChildPanels or something) that returns the child OptionsPanels for that panel. Once the user selects an OptionsPanel then, he can look in the property grid to find its ChildPanels property and add child panels to that.
There is a problem though: what would this property return? It must return a ControlCollection of some container (this is, I think, a requirement for the designer features to work, otherwise panels are not added to the Form.Designer.vb file). But there is no container. I cannot add them to the OptionsPanel itself, that would make no sense because the parent OptionsPanel has its own set of controls (the options itself...), there cannot be another (fully docked) Panel on top of those obviously.The container of the main OptionsView then? That is not an option either, its Controls collection holds ALL OptionsPanels, not just the children of the selected panel. I cannot 'select' only the right panels either, that would require me to return a new instance of ControlCollection, it would be impossible to return the actual ControlsCollection that holds merely a small selection of its controls.

As i'm learning more and more about developing ive just got my head around creating classes and modules, i started wondering about something to do with configuration of applications where deployment is in a more diverse environment say in a company where different branches dont need access to all parts of a program, so i thought id throw the question out there in a basic sense and get some feedback. so i can go off and do some more reading and learning.
So the scenario in my head is like this.
So we have for arguments sake FrmConfig which is the master configuration form, then we have FrmMain which is the root menu our application general user interfaces with. So here based on what options are checked as enabled in FrmConfig effects what controls (like buttons/menu options) are enabled in FrmMain.

how to get different backcolors and how to change them using ListView.ItemCheck.
I am using ListView in a self written control (basically to improve padding). In some deployments, CheckBoxes is set to true and I use a RaiseEvent to return the Index of the row selected using an ListView_SelectedIndexChanged event.
In other deployments, I am using the control with the CheckBoxes set to false. But clicking on a row does not fire the ListView_SelectedIndexChanged event to be able to use RaiseEvent to return the Index of the row chosen. I have tried using a MouseUp event to capture the mouse Y coordinate. But conversion of that coordinate to an Index position is both inconsistent and inaccurate with my primative code of
return = (point.Y - me.top) / some constant
I have used ItemHeight on a ListBox in a similar situation but ListView does not have an ItemHeight property.
how I can capture the Index of a row clicked in a ListView without checkboxes?

What I would like to do is to show a dialog when the program starts that let's the user choose which database to use. My idea is to create a new form as the starup form that sets this property and then launches the main form.Currently the connectionstring is specified in the application config file. Best would be if I can specify two different connection strings in that file to choose from, but for now it is also acceptable with other solutions like hardcoding the two connectionstrings into the startup form.EDIT: In the dataset.xsd file there seems to be the relevant part
