I am trying to use vb to open windows 7 visual effects in control panel and only select certain options then saving it. Either buy making vb do all the work or making vb find the registry keys.

I know I can open the control panel item by using the following command
%windir%system32SystemPropertiesPerformance.exe.
However what I do not know is there a way to programmatically select the options on that control panel item? For example in a vb program I can launch that panel quietly have the program select "adjust for best performance" or select "let windows decide" Apply it and then close ?
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.
I have created a (kind of) 'Desktop' Form for the main basis of my program. Basically it is made up of 3 panel controls.
1. Holds all buttons which load the different forms (Like the windows start menu when expanded). name: StartMenuPanel
2. Holds Information on log in deatails. name: LogCheckPanel (very thin panel at top of screen)
3. Main panel which takes up the majority of the screen (where I want the forms to load). name: MainPanel
My aim is: When a button is clicked from the 'StartMenuPanel' the form will load with-in the 'MainPanel'.
I tried changing the start position to 'centre parent', but the panels are in the way so some of the childform is overlayed by the panels.
[Code]...
When I run this I get the following error: 'Top-level control cannot be added to a control'.
I hope I've explained this well enough.
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.
Does anyone know if Windows sells this control that is used in Visual Studios:
I'm not really sure of it's name, I just call it a Panel Docking Control. I'm looking for any 3rd party versions of it also.
I have two drop down. SelCurrentManuf and selCurrentModel. I want the option in selCurrentModel to change depending on the option selected in selCurrentManuf. How do i do it?
<asp:DropDownList runat="server" ID="selCurrentManuf"></asp:DropDownList>
<asp:DropDownList runat="server" ID="selCurrentModel"></asp:DropDownList>
This is how i am currently populating selCurrentModel
Public Sub PopulateCurrentModel()
Dim mySelectQuery As String = "SELECT * FROM Model where ManufID = "+ selCurrentManuf.Text+";"
Dim myConnection As New MySqlConnection(Session("localConn"))
[Code]...
but it only populates the first selected manuf, and doesnt change after
Private Sub selCurrentManuf_SelectedIndexChanged(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles selCurrentManuf.SelectedIndexChanged
PopulateCurrentModel()
End Sub
I am designing a simple user interface using winforms. In the designer I have a panel on the form and would like to add a datagridview control into the panel at runtime and set the dock property of the datagridview to 'Fill' so that it fills the panel.
I am struggling to do this and following code is not working out for me:
Dim MyDataGridview as New DataGridView()
MyDataGridView.Dock = DockStyle.Fill
Me.MyPanel.Controls.Add(MyDataGridview)
I don't get an error but the datagridview isn't visible. It gets added 'behind' the panel and so I tried using .SendToBack() and .BringToFront() methods thinking that the panel was hiding the datagridview but this doesn't seem to work either. At any rate, it seems like the datagridview is being added to the form but just not docked within the panel
how to code a form that has 2 text and a tick box. When the user selects the options he needs it keeps the options they selected when the form loads next time round once the user has closed it. My first thought was hold the options in a text file but glad to hear any further ideas on that.
View 1 RepliesI was trying to code a save option for my project, it's a spammer that I have created and I have made it to where people can have their own personal spam message and when they want to use it all they have to do is click a radio button and the text will appear in the text box. Now like I said I want it to save, like they make their own customizable spamming options and then save it so they want have to continue typing in the message because that would defeat the purpose of my project.
Here is the code:
TextBox2.Text = (TextBox2.Text)
RadioButton1.Text = (TextBox2.Text)
TextBox3.Text = (TextBox3.Text)
RadioButton2.Text = (TextBox3.Text)
TextBox4.Text = (TextBox4.Text)

Though it wouldn't work unless I imputed this code
Private Sub SaveSetting(ByVal p1 As String)
Throw New NotImplementedException
But when I start the program it quits and says the " NotImplementedException" is unhandled:/

I am currently in the process of improving my options dialog for a winforms application. At the moment I am using a tab control. I would like to create a form/dialog for settings that is similar to Visual Studio's. How is this done? I can see a treeview like control on the left hand side but what control are they using to display each of the options pages, it doesn't appear to be a tab control. I would like to be able to build the controls for each of the settings at design time.

Then I progressed to using the tabcontrol and multiple tabpages to group associated data for manipulation.I'm thinking the treeview control could be used to create a slick options page, however with the previous methods all the controls were drawn in design time, making it easy to edit events/properties etc.., I can only think using a treeview control on a single form that controls would need to be added programmatically/dynamically.

I've got a Panel on a main Form containing a PictureBox control on Top of a TableLayout control. Both the child controls have their docking properties set to Top. The Picture control has sizemode set to Zoom.
What I'm finding is that the picture doesn't size properly when I start the app. There is a border at the top and bottom in the PictureBox control. It's only when I resize the overall form that it's correct.
So at the moment I've got this ugly bit of startup code, just to fix the problem Me.WindowState = FormWindowState.Normal Me.WindowState = FormWindowState.Maximized
What am I missing?
