View 2 RepliesWhen you add a label from the the toolbox, the default font is always Microsoft Sans Serif, Regular, 8. I like to use Ariel as my font of choice. Is there a way to change the default font setting so I don't have to pick the font I want every time? I've looked under Tools->Options->Environment->Fonts and Colors and I can't find it there.

View 2 RepliesI am inheriting my own DataGridView (say MyDataGridView) from the standard DataGridView control. What I want is that certain properties of MyDataGridView should have a different default value than what its base have. For example, AllowUserToAddRows, AllowUserToDeleteRows, AllowUserToResizeRows properties should have the default values of False; so that when I drag MyDataGridView into a form in the IDE, the default values shown in the properties grid should be False. Later on, if I want to change them to True from the grid, they will be set accordingly.
View 1 RepliesI am creating a customised version of the ListView control and there are several of the properties that a ListView has that I would like to be set to a different value to the ListView default when a user goes to use my user control.
From what I've found there seems to be a number of people suggesting just set them in the constructor, but to the best of my knowledge that would just mean that the user would not be able to change the properties in the PropertyGrid in the VS IDE.I assume this is probably something extremely simple that I have overlooked.
I have been trying to create a custom control based on the ListBox called FileListBox. I followed Microsoft's walkthrough but am having some trouble.
What I want is to add another property to the ListBox called SafeItems which is an ObjectCollection of strings (like the Items property). I will use the Items property to store a collection of Filenames as strings and I would like to store the corresponding SafeFilenames in the SafeItems collection.
This is what I've tried:
FileListBox.Designer.vb
<Global.Microsoft.VisualBasic.CompilerServices.DesignerGenerated()> _
Partial Class FileListBox
Inherits System.Windows.Forms.ListBox

I created a Custom Class and Implemented a Type Converter for it. I used this Custom Class as a new property of a Custom Control.Everything is fine at design time. I can set the values of this property but at run-time the values i entered resets back to the initial declaration i made.
View 5 RepliesI'm trying to create a button that will hide the panel that I have docked at the centre of my user control. [code]This works to an extent.

View 1 RepliesI have created several simply custom controls and I used them in my app. Now, I changed the background color in a custom control class, because I wanted an other color for this type of control. But in my app, the background of this controls didn't change. Why? I assume, I don't need to place again this controls on each forms to get the new background color, or do I? If yes, this is very stupid in my opinion.
View 4 RepliesIf we say blue is the default colour of the Backcolor property I understand it as if you don't specify a colour for Backcolor blue will be its colour. But I could not make sense of default property of a class in the context of building a custom user control. After calling an instance of a class we have to either call one of its members or assign an other object for it. Therefore why should there be a default property?

View 10 RepliesI believe that the correct way to give a property a default value is to use the Default Attribute on the Property.[code]In the property window, the value that's displayed in a grid's property bag when it's newly dropped onto a form is False, not True. It does recognise that the default value should be True because it shows the value as bolded and then de-bolds it when we manualy set it to true - but it doesn't respect the default as the initial value. Is there any way of getting the property bag to respect the default value?

I have a 32x32 icon that is saves as .ico but it doesn't work.

My objective: Set the printer to use without changing the default in Word under the control of vb.net express 08. Word version is 2000
I have it working, but� Through a lot of trying, I discovered that the WordBasic line would work. Further exploration revealed the �with dialogs(13)� will work. In a Word macro it would be Dialogs(wdFilePrintSetup) or Dialogs(97)
This is where it gets interesting. While Word.WdWordDialog.wdDialogFilePrintSetup equals to 97 it doesn�t activate the correct dialog. After considerable trying, I found that index 13 does yield the correct dialog box.

For a given class, with a default property of list, you can access an instance object in the list by doing myClass.defProperty("key"). You can also achieve the same results by typing myClass.defProperty!Key.
I have been told that using the parenthesis and quotes is faster for the way the runtime accesses the Property, but I'd like to understand what is the difference and how do each work...
I understand C# has a similar behavior by replacing the parenthesis with square brackets.
Is there anyway to have a class that can return a default type without specifying the property.
If I had a class that had a few properties and one property returned a string value and others returned additional types, could I do the following?
Dim StudentGrade as new StudentGradeClass
'call and get default property
Dim CurrentGrade as string=StudentGrade
'instead of this
Dim CurrentGrade as string=StudentGrade.Current
The reason I am asking this is when I have classes that have other classes as properties and would like to just get a default return value,.
I'm attempting the following:Default Public Property Data(Of dataType)(ByVal key As String) As dataType
Get
Return DirectCast(values.Item(key), dataType)
End Get
Set(ByVal value As dataType)
values.Item(key) = value
End Set
End Property

It made more sense to make it a property, and it would be the default property of the class. The data type can not be specified on instantiation of the class, because it can contain multiple objects of different data types.

Default Public Property Data(Of dataType)(ByVal key As String) As dataType
Get
Return DirectCast(values.Item(key), dataType)

I am using a custom built driver to communicate via Modbus TCP with a Windows CE Controller.
There is a property declared in the driver as a SHORT. I need this property declared as a LONG. I have tried everything I know of to change this programmatically but I am having no luck.
' Declared in the class
Dim dev As vHMIModbusMaster.CDevice 'this is the Modbus Comm Library
Dim WithEvents MBSerial As vHMIModbusMaster.CModbusSerial
Dim WithEvents MBEthernet As vHMIModbusMaster.CModbusEthernet
[Code]....
Address is sent to the event from a timer event. It is the .Memory_StartAddress that I need to be a long.
I come from a VB6 background and have only recently started using .net. The developer of the driver has been very slow to respond and I am having a hard time convincing him that the problem is with his code. The thing is that it works fine as long as I send an address less than 32767.
