Select Multiple Options And Unchecked It In Menustrip?
Sep 15, 2009
Im creating a menustrip which can choose to draw the shape you want, and the colour you want to fill in the shape.For the colour part, I manage to choose multiple colour options. Example : If i checked red and blue colour, the shape of the colour would be purple. But when I want to uncheck the red color or blue color, it does not work.
Public Class Form2
Private Sub ExitToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ExitToolStripMenuItem.Click
Me.Close()
End Sub

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

I am a vb6 enthusiast willing to try NET. I am confused by all the versions and the fact that limitations of the 'free' version are not spelt out. My requirement is to be able to convert vb6 applications (possibly, but don't mind a manual rewrite), to write applications (not for tablets or phones yet) that I can use myself and possibly publish to others. I would like to allow printed reports for my financial applications. I will have a small home network up soon but ability to operate on a network is not critical. I do NOT want to download a 'free' version and find that it is crippled one way or another, like allowing development but not publication.
Whether the 'free download' is OK, and which one (Express?), or point to a site where the versions are clearly laid out.

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.

I have a question regarding the dataset usage in Reporting Services. I have a stored procedure which returns multiple select statements (result tables), and I created a Dataset in Reporting Services 2005 with this stored procedure. The problem is that I can not reference the second or third result table, and I can only use the first select statement fields. Is this the limitation on Reporting Services Dataset or is there a way to use multiple table results in one dataset?

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 problem and I've been looking for a week now on how to solve it. Yesterday I thought I solved but apparently I didn't when I tried the query with new data added in my database.Here's my query
Public Function getTicketsByBeginstation(ByVal station As String) As Array
Dim r As Array
r = (From u In treinDataContext.Tickets Where u.ritId =[code].....
The problem I have is: when I have a station selected there are more than 1 trajecten (connections in English) but I had to use the .first else Visual Studio would give the error "the '=' operator is not defined for 'integers' and 'system.linq. IQueryable(of integer)".
So I give the name of a station -> I have to select all trajectens with the given station as beginstation -> I have to select all ritten which have the given trajecten -> I have to select all tickets which have the given ritten So: I have to show all tickets for a certain station.

I am writing an app that puts multiple controls on a form at run time and then I edit the controls in a property grid. All that is working fine. I'd like to 'mark' the contol when it is 'selected just like visual studio does with the dotted border (or soemthing similar, I don't care that it is just like vs). I'm already using MouseDown event to grab the control and send it to the PropertyGrid, but I have now wired it up to take multiple controls and need to 'identify' them on the screen.

I am creating a page in which I need to show a drop down List. From this drop down List a user can select multiple values. I know I could use a check box list like:
<asp:CheckBoxList ID="CheckBoxList1" runat="server" style="margin-right: 158px">
<asp:ListItem>Value 1</asp:ListItem>
<asp:ListItem>Value 2</asp:ListItem>
[code]....
but if there are more than 50 or so values then that will consume a lot of space on the page and will look odd. So kindly tell me how can I select multiple values from drop down list or if there any alternatives so that I can select multiple values and show many records on a minimum space but not a grid?
