Asp.net - Child Properties Not Initialised Automatically With RIA?
Feb 2, 2011
Within my project I have created an Entity Data Model, complete with relationship links between the various tables. I notice when I do so, Visual Studio automatically creates a property named after this link.
I have then generated a Domain Service Class based on this data model, and once again within this a property is generated representing the link, ie within my ChemicalApplication class there is a Chemical property of type Chemical.
The trouble is, within the silverlight client, I can access the ChemicalApplication data object no bother, and can see the ChemicalApplication.Chemical property, but as soon as I try to access it, I recieve an error that the property is not initialised.
Do these auto-generated child properties not automatically initialise? If not, how do i manually assign a value to them within the RIA Domain Service?

(VS2005 Professional)
My database's layout is as follows:
Identification (Parent table)
ID# (Primary Key, auto increase)
First Name
[Code]....
I am placing this three tables in three tabs by a tabcontrol. If I put two child tables in dataGridView in their tab, the insert(new record)/update to the tables works very well. When I put the child tables in details View, I can't get a new record updated. The problem with details view is that there is no AddressID and VehiclesID generated. In dataGridView, these IDs are automatically generated whenever a mouse enters into a cell in a row.

Using Visual Studio .NET 2008 or 2005, is there a way to automatically generate properties for each column in an SQL Server database table? I am assuming other code-generation software exists that will do this. I know with Visio I can connect to my database and it will generate diagrams by table, this would be similar to that.

I've got a groupbox on my form. I changed its font and fore color. The problem is that when I add a button or any other controls like a label, checkbox etc to the groupbox, the controls are automatically changing their fore color and font to that of the groupbox. How to prevent this?

I have a custom class (Class1) with a bunch of properties. One of the properties of this class is another custom class (Class2) with its own properties.I have a property grid with the selected object set to Class 1. I can see Class 2 as a property, but i would like to expand Class 2 to show its properties in the same property grid.
Im basically trying to do the exact same thing as the Font Class on a form. If you look at the properties of a form in the designer, you can see the font property. You can then expand that to show the properties of the font class.

I am using XElement to manipulate my xml file: to find target node and then add child node to it. But now I have one problem. Let's say my xml file looks like this:
<Report xmlns="MY_NAMESPACE"
<Width>100</Width>
<Height>100</Height>
[Code].....
The second <ReportItem> is the newly-added one, but sadly this is not a valid file (my parser is complaining in the further processing of xml file). So how can I make this new item look exactly like the existing one, without any namespace? This has been driving me crazy. I spent a whole day to figure out that I need to add the curly brackets so that it will find the target node (it doesn't work like what the link above says that it adds and searches the default NS automatically), but now it adds something unnecessary?

The company has a Visual Studio 2010 Ultimate project that is written in Visual Basic. The project has several strings in the resources file (Resources.resx). One of those strings (VersionSuffix) contains "" when we are distributing a normal version of our product and "BETA" when we are distributing a beta version of our product. Most of the time we distribute a normal version of our product. Therefore, most of the time the resource string VersionSuffix contains "".
Recently, we attempted to distribute a beta version of our product. Therefore, we changed resource string VersionSuffix from "" to "BETA". However, it quickly became apparent that the resource string VersionSuffix was being used as the default value for several control properties in the form designer. For example, if I draw a rich textbox on a form then file FORMNAME.Designer.vb will contain the following.
Me.RichTextBox1.Location = New System.Drawing.Point(286, 306)
Me.RichTextBox1.Name = "RichTextBox1"
Me.RichTextBox1.Size = New System.Drawing.Size(134, 33)
Me.RichTextBox1.TabIndex = 32
Me.RichTextBox1.Text = Global.PROJECTNAME.My.Resources.Resources.VersionSuffix
We are unable to find anything anywhere that indicates that this resource string should be used as the default value for control properties. Therefore, we have no idea why this resource string is being used for this purpose. We would like to change the control property assignments in the designer from Me.RichTextBox1.Text = Global.PROJECTNAME.My.Resources.Resources.VersionSuffix
Me.RichTextBox1.Text = "" However, we don't know why these strange assignments are being made. Therefore, as soon as someone adds another control the problem will most likely return. Does anyone know why this is happening and how to prevent it from happening again?

This is another one of my "I think it's not possible but I need confirmation" questions.I have a base class for a bunch of child classes. Right now, this base class has a few common properties the children use, like Name. The base is an abstract class (MustInherit)Technically, this means that everytime a child class is instantiated, it lugs around, in memory, its own copy of Name. The thing is, Name is going to be a fixed value for all instances of a given child. I.e., Child1.Name will return "child_object1", and Child2.Name will return "child_object2".

I want to set a property of an object that is an array type. If I was declaring and initialising an array of objects, I'd do this: Dim x() as SomeObject = {obj1, obj2}
I don't seems to be able to do something similar with the property, can you do this, does anyone know the correct syntax? myObj.ArrayProperty = {obj1, obj2}
I get Expression Expected Error on the first {
Infer Off
Explicit On
Strict On
Answer : myObj.ArrayProperty = New objType() {obj1, obj2}

I have multilingual application that was done in VB2005.We recently had a request to translate the application to Arabic (Egypt), so I have been happily running through all of the forms and changing the layout for Right to Left format.I have 2 forms that are problematic though.On one form, whenever I select Arabic (Egypt), it will automatically switch the selection to Arabic (Saudi Arabia) and try to add an ar-SA resx file.On the other problematic form, if I choose Arabic (Egypt), the IDE will automatically select Chinese (People's Republic of China), then copy the contents of my ar-EG resx file into the zh-CN file, overwriting all of our Chinese translations and layout changes with the Arabic ones.

The following code does create a form within a form and does place NotePad inside the child form. You have to manually start NotePad prior to execution (I work on that later) but the code does workŠ My problem is now I want to manipulate the properties of notepad i.e. focus, size, location, etc. but I cannot figure out how to reference notepad and its properties.

My program handles XML files that have certain elements within a root-child node that are identical expect for their inner text value. So while populating my combo box with all of a root-child's child element's names I get like five identical items listed. Which brought about the problem of selecting say the third item and getting the value of the first displayed. So I came up with a loop function that determines if the selected combo box item is preceded by one of the same name, if it is, then it adds +1 to a counter variable and keeps checking farther and farther up the list. Once it loops to an item that doesn't have the same name it exits and it reads the Xth (X = counter mentioned earlier) element's inner text from the file. This works great for elements 1, 3, 4, and 5. But not for 2. A while back when I was focused on this problem I discovered the root of the problem but I was unable to circumvent it. I'll put the loop below so you can see the problem in action instead of trying to follow my verbose explanation:

I'm from denmark and hope I can explain my question for you. This is just a example: I have a panel, let's say panel1 and another panel on that panel (panel2) and so on until for example panel5 - on panel5 I have a button (button1). Now I would like to change button1's backcolor property through code how do I then get access to button1, now it's a child-control on panel5 that is a child control on panel4 etc. ??

I'm making a control and I am trying to finalize my design time properties grid. I have several List(of Class) items as public properties and when I click on the design time menu (while testing the control) there is the word "Collection" and a button with an ellipsis (...) that brings up a neat pop up with the buttons Add/remove and all of the public properties of the collection's class on the right hand side. Basically for a non-collection instance of a class (with public properties) I'd like a similar button to show up. I know I could put all of the properties in the main control class and group them, but I like the pop up box feature. Anyway to duplicate this? (think font grid item etc.)

In the form design I set up a TableLayoutPanel, 20x20 cells and in cell (1,1) a PictureBox (called Target) containing the image of a small target. The properties box for Target shows some very promising properties, Column and Row - and if you overwrite the values in the properties box, the PictureBox obligingly shifts to the corresponding cell position in th design. However in VB it is not possible to refer to Me.Target.Row or .Column - neither appears during coding in the menu of properties, and deliberately coding either of them produces an error like
Error 1 'row' is not a member of 'System.Windows.Forms.PictureBox'.
1. Why does the properties box show properties that cannot be altered programmatically?
2. How can my program move Target around in the TableLayoutPanel?

I'm working on a Hazardous Materials label printing program. One of the options is to do an "NFPA" label. Since there are 4 values required with 4 or 6 options, the ratings are entered via radio buttons in a group box. That's working okay. I display values in the NFPA diamond as they're entered: left quadrant blue, top quadrant red, left yellow, bottom red. I'm having trouble with the label in which the rating will be displayed on top of a jpg diamond for the white. In this quadrant the text can be up to 4 characters. I can accept the text going into an adjacent block a little, but the corners of the label overlap into another quadrant/color. I reduced the font size which solved the overlap problem but the font is then too small and looks terrible. I tried to make the background of the label transparent to let the color come through correctly but that's not a valid value for label.background. I'm figuring that the transparent background is the best solution. What can I use that will accept a transparent background so the color shows through?
I'm trying to set the transparent property via label properties properties, not via code. Here's the code if it makes any difference:
Public Class NFPA
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Close()
End Sub
