I'm new to VB in Visual Studio 2008 and am just trying out some simple test.I just want to change the Font & Boldness of some text but get the following errorProperty 'Size' is Read onlyI have been browsing the forums and it seems that changing the font size etc isn't as simple as
TextBox.Font.Size = 12
TextBox.Font.Bold = True
Is this true, and if so what do I need to do
Conceptually it seems like a derived class should be able to override a readonly property with a read write property. Why isn't this possible?

Why does a Panel control have a Font property? What does it affect? Any controls added to the panel will have their own Font property that controls their appearance, so I don't see the point of the panel control having a Font property, especially since it has no text property.
View 2 RepliesI'm in the process of converting an old VB6 app to VB 2008. I just discovered the my.settings class. Great way to store user data instead of using the registry (Reminds me of the old days when every app had a config file).Why do I get the error "Property is read only" when trying to write to My.Settings. I copied an example right out of a book and its not working
This works fine:
label1.text = My.Settings.DBLocation
This generates an error:
My.Settings.DBLocation = text1.text
I created a richtextbox on a form, a button to invoke the font dialog and another one for the color dialog.
Now user can type in any text and change the font size and color. It looks very nice customized on the screen. I saved it as and txt file.
I open the file to read. It is no more as colorful as when I type in. I 'd like to save the file with those customizetion so when the read on the other end will able to see what is important in the message.
I don't understand why you can't set some of the font properties of a label at runtime?

View 5 RepliesThe code below does not alter the value of the TextOut Property in the sc object (an instance of SomeClass).But none-the-less the Set routine for TextOut is invoked.There's no other way that the TextChanged flag could become True.But that's what happens when I run the code under VB2010 Express (the only place I have tried it).
Does anyone think that this is not a bug in the compiler?
I know that the problem is related to, maybe caused by, the fact that the first argument to LookAtTextOut ("whatever") is passed ByRef.But I do not see how passing an argument ByRef should result in calling a Property's Set routine when there is no code in the subroutine which changes the argument.[code]....

I have a class which contains the object and a collection for that object. I want to make a property readonly to external calls, but allow access to that property from the collection class. I know I can use:[code]But, I want to the PreviousRow property to actually show as "ReadOnly" in the intelisense of the calling code of client app. The above does not. The only way that I see to make it show as "ReadOnly" in the called code is to mark the whole property as ReadOnly, but the problem with this is that my collection class code can no longer access this property:[code]I tried using the "Friend" declaration, but that seems to still allow Write access to the calling code.I only want write access from within the RowCollection class.

View 3 RepliesLet's say we have a class, let's call it CLS_Object for simplicity. Now, suppose CLS_Object has 2 public properties, "Name" as String and "Value" as String. These have both read/write methods into the properties.
Now let's go to a seperate class, let's say CLS_Example. Let's create this variable:
Public
_OBJ_Object as New CLS_Object
Now, let's create a property, called PROP_Object that is READ ONLY...
Public ReadOnly
Property
PROP_Object As
CLS_Object
If we allow that to return _OBJ_Object, the user can the also SET VALUES to that object. In the context of "well, the property is returning the object and you are writing to the object, not the property", I understand this behavior. But it means you can write to a read-only object of sorts.
Is it possible to read a label's text property of another app? I know how to get the handle of the main window, and how to get the handle for a child. But the problem is that there's like 20 other labels on the window and when I use winID to get it's class, it's just "Edit", and it's the same for all the labels. And the title is the value of the labels text property. [URL]

I'm struggling a bit with Entity Framework 4.x. Let's say I have a model called Product. It was generated from a database table. There is a field in this entity called CreatedDate. The MySQL database has a default value for the current timestamp. I don't want Entity Framework to set this field when inserting or update the table. Problem is, I can't seem to figure out how to tell EF to exclude this field from being sent back to the database, but still retain it as a field to be viewable in the application.
