Many Different Options - How To Display

Nov 21, 2010

I've got a project where each "person's profile" will have many options associated with them, they are broken into groups such as

"Hobbies"
"TV Shows"
"Dinners"

What I was going to do it tick each "group" that applies to each profile and show only the fields that apply to the user.I was going to display them on a panel or a tabpage but How would I show the user what panels need data entered? (there could be 3 or even 4) but would the panels 2-3(or 4) be hidden how would I promt the user to enter data.I don't like the "look and feel" of tabpages.

Printer Preferences - Paper Options (Type Is)

May 7, 2011

My HP LaserJet 1018 Printer Preferences has "Paper options" with four options: Use different paper, Size is, source is, Type is. "Type is" has options such as: Plain, label, card stock, envelope etc. Apparently this information is relayed to the printer and affects its operations. In my case when I put in labels the heavier paper is not pulled correctly and the registration is often off. How can I choose one of these from VB 2008 .NET? I find "paper size" but not "type is" among the many options for Printer Settings.

VS 2010 Options View Control - Child Options?

Aug 20, 2011

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.

Hypothetical Controls - Options Checked As Enabled In FrmConfig Effects - Controls (like Buttons/menu Options) Are Enabled In FrmMain

Nov 26, 2010

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.

Display Queried Results In Textbox Where Criteria In Another Textbox 1 Form

Jun 21, 2010

I have a database I am creating with about 50 users over a network. There are about 6 groups of users and these users are spread across 10 branches. I want to block/allow users from particular forms and views. For example I want branch users forms to be filtered by their branch number but depending on the group they are in they can only see some forms. i.e. 50 users, 10 branches, each branch has about 5 ppl of where 1 is in group A and 4 are in group B. I want all users that belong to branch 1 to see the information they enter, but Group B enter data but cannot approved or delete, and group A can enter, approve and delete. So then. On my login form I have the user type his/her username but the i want LEAVE function to update 2 textbox where I have named GroupName and BranchNo. Basically to run a query and look for the username and return in one textbox that user's groupname and the other textbox the user's branch no. This information will be used to filter forms and block the user from certain controls. This is the code I have so far but still can't figure how to display the results.

Private Sub UsernameTextBox_Leave(ByVal sender As Object, ByVal e As System.EventArgs) Handles UsernameTextBox.Leave
'Make Connection to database

It keeps highlighting the BranchNumber and UserGroup and giving error "Value of type 'String' cannot be converted to System.Data.OledbCommand

Can't Type In A Textbox That Shows Cursor

Jan 15, 2010

I am having some bizarre issues with getting focus on the child objects of some user controls that I am developing.The base control, DatePanel, consist of three radio buttons, a textbox, a combobox, and a datetimepicker.Depending on which radio button is selected depends on which of the other controls are visible.The default state of the control has the textbox and combobox visible.When I test the control in the VS test container, I click in the textbox, the cursor appears but I cannot type, if I click in the textbox again then I can type.I have tested enough to figure out that if I click on any other control and then click on the textbox I can type.I have tried adding a gotfocus event for the user control to both Focus and Select the textbox and neither does anything.This user control is on several other user controls that are in development because I didn't catch the behave at the beginning.To make things a little stranger in one of the other controls, I found that if I set the tabindex of DatePanel A to 0 then I was able to type in the textbox after selecting it the first time, however if instead I click in the textbox of DatePanel B the cursor appears in that textbox but when I type the text appears in the textbox in DatePanel.

In terms of code on the DatePanel there are 6 properties and 3 events.The 6 properties return values of the fields on the DatePanel and the three events are for watching the state of the radio buttons.Other than that I did try adding the GotFocus event to no avail.I can provide any code that is needed but between myself and my colleagues we couldn't see anything that would have any influence over the control focus.
