I need a control, like a Label in WPF. But this Label should be always autosized(Width = Height = Auto) - user should not be able to modify it.Also the BorderThinkness should be always = 0. How can I do it in WPF? Is it possible to inherit such a label, in order that the children conserve that property (always AutoSized)?

I'm having a few problems converting some code into VB.NET from C#. Most of the translating is done, but I am getting errors when I try to run my code, and I can't figure out what is causing them. Here is the Sub I translated.

blue.Green = 0

The error I receive on this line ("vision.Widgets.CreateWidget(wg1)") reads "In order to evaluate an indexed property, the property must be qualified and the arguments must be explicitly supplied by the user."
I receive a System.Data.SqlClient.SqlException in the following code: Specifically Incorrect syntax near ' In order to evaluate an indexed property, the property must be qualified and the arguments must be explicitly supplied by the user.

I would like to be able to set Control visual properties such as color, boarder, flat style, etc. on the base class of the control so that as I add new instances of the control, each instance inherits the visual properties of the base. I have tried using Application Settings but it appears as though I need to reference an application setting manually each time I add the control to a form. This is a Windows Form question.
View 4 RepliesI have some related Properties in a class. Namely, One is a collection of objects and the other is an index to the one that the class instance is looking at. In the designer, I need for the collection to be set prior to the index. I tried to do this manually, but when the file is saved, the Designer goes back and writes over my change. So I need to know how to tell the designer in which order to set the properties.
View 2 RepliesI've created a custom control in VB.NET on .Net 3.5, in VS2008, which contains a load of custom properties, including RSS feed address, proxy address and proxy port.This control is an RSS ticker, which works really nicely, but doesn't initially run at all, and from stepping through my code, this is because none of my properties are being passed data from the containing form, until after the control has been initialised, and the code behind the control has run. The code (relevant bits) looks as follows:[code]

View 1 RepliesI have a class where it's problematic to relay on the properties being serialized in alphabetical order at design time.In other words, property Z must be serialized before property A.The problem arises because property property Z clears property A whenever it changes - which happens in InitializeComponent.I work around this problem by setting a FirstTime flag, but that seems messy.
View 2 RepliesI get the following string expression provided:"ChildObject.FullName" ...where ChildObject is an instance property on the MyObject1 type.ChildObject has a property named "FullName" and I want to sort a collection of type "MyObject1" based on this child properties "FullName" value.
I can do this all day long on properties directly on MyObject1 but I run into 2 challanges when doing it on a child instance and I can't get all the pieces working. The main 2 challanges are:
MyObject1 has a few different child property types so I can't hardcode the type for ChildObject. The string could be of any type.The sort expression is a String and not a known type.Above the value returned from the last line in the expression (if I run the code outsode the OrderBy method, does provide me the 'FullName' information I need. So the code must be close, but it still does not work.
Any ideas on how I can accomplish this? What I am trying to prevent is hardcoding a series of 'If' blocks on the child's type to then hardcode in its type to the sort or OrderBy method.

View 3 RepliesI am converting a 1.1 .NET web app to 3.5, and I've run into a bit of a jam.
One web control has a Property that sets the page title label on that web control.
End Property
When a page with the web control was loaded before, it would set the Property to a given string, like in ucHeader.PageTitle = "This is a string." Now, if I don't remove the lblPageTitle.Text = Value, I get a NullReference Exception.
I have an array of labels on my form which are all named "lblLabel1" thru "lblLabel9", but I want to be able to take a users numeric input (lets say 3), and display the 3 on lblLabel1, then I need it to increment by one all the way to lblLabel9. How can I do this? I was thinking a loop so this is what I came up with, but it didn't work:
For b As Integer = 0 To 8
lblLabel(b).Text = String.Concat(intSomething, "+", intAnother, "=")
Next
'Where b = the label number (I know it's zero based, I would change it later)

View 7 Repliesi frequently have troubles with the dock property. it seems that either the order of creation or adding to the parent control determines whether or not a control's dock property supersedes another's. e.g. a control with the dockstyle fill will overlap with another docked control on the same parent. does anyone know what the rules are to determine how docking will behave; particularly in dynamically created GUIs?
View 2 Repliesi would like to be able to double click on a label for a text box and write a value into the .tag property and then change the color surrounding the label.for example.. if the user double click the default label..(which looks like the stardard label) then I would write a "1" to the tag property for that label, and at the same time, change the line color surrounding the label to red(maybe even changing the thinkness of the line).
when the user would double click the label again.. I was see that it was already selected and change the setting back to the default.

View 2 RepliesThose who are looking for an example like this, might find it useful (or not). I know i was looking for one like this for over a week. Ok now, to make this codes work properly, you have to make a Database in Ms Access (I used MS Access 2007) . Create a table of two Columns, one name Debit and one name Credit. Both of the Columns Data Types must be Long Integers or you might get some conversion errors at run time. Now save the database in Access 2000-2003 Database format. And last of all, put the database in your projects DebugBin directory to avoid the database Connection Errors.

I want to alter the .visible property of a label based on if a variable is positive or negative (Hiding it for negative values)
But I want to do this for lots of labels so If Statements are too bulky.
I tried this:
Label1.visible = CBool(IntVariable1)
But it turns out CBool returns True for ANY value and False for Zero.I'd assumed it would be True for positive values and False for negatives.How can I do it without if statements?I considered Modulo or SquareRoots to somehow convert a negative number into zero, but didn't want to complicate things with imaginary numbers.
I have a combo box bound to a datasource. I need to change one combo box (of many) to order the items in descending order.I'm guessing I could order the collection in the dataset, but that will mean all my combo boxes will be reordered?
View 2 RepliesI have a databound Datagridview. The DGV is bound to a datatable of a strongly typed DataSet created using the wizard. Is there any way to re order the columns before displaying them eg: the Columns are displayed in the DGV in this other Col4, Col6, Col3, Col1,Col5, Col2
But I want to it to show as Col1, Col2, col3, Col4, Col5, Col6?
I realise that the display order followed the Column order in the database table and by extension, the datatable. I have re-arranged the columns in the Database but the Datatable still retains the old order.
